Herman Warner Muntinghe (1773-1827), the protagonist of this study, was the main architect of the new colonial state that emerged in the Indonesian archipelago in the early nineteenth century. This book focuses on the question of how ideas from the Enlightenment took shape in the Dutch colonial state formation in the Indonesian archipelago and how Muntinghe, between 1806 and 1827, collaborated with his superiors, to develop and implement these ideas. The key to this development of ideas about colonial governance was not primarily in The Hague or in Batavia, but in the interaction between contemporary political theory and practice in the Indies themselves and the rest of the European colonial world. Many concrete plans did not originate from the drawing boards in The Hague, but from the colonial experience in the archipelago. Therefore this study pays special attention to the opposing forces in the Indies. The response of the population to colonial policy largely determined the leeway of the government in Batavia. The early nineteenth-century debate on the future of the former VOC possessions in the Indonesian archipelago was pre-eminently transnational in character. Ever since the 1770s, Batavia has been closely monitoring the rapid changes taking place in British India and the new forms of exploitation being tested in that colony. The British example was frequently quoted in the publications of Dirk and Gijsbert Karel van Hogendorp and later in Muntinghe's writings. The major issues concerning the British East India Company were the subject of debate in the British Parliament, and they were well covered in the newspapers. The colonial discourse thus had a much more public character in England than in the Batavian Republic. My research confirms how the ideas in the British and Dutch colonial worlds around the Indian Ocean influenced each other. In this study I use Muntinghe's biography as a lens to better understand the origins of the colonial state. By connecting h

Education often involves categorizing students into broad groups based on perceived attributes like academic abilities, learning pace, and unique challenges. However, the validity and applicability of these stereotypes require closer examination. This research investigates student grouping factors, exploring both conventional variables like gender and education level, as well as innovative methodologies that utilize students’ problem-solving behaviors. The study critically evaluates the effectiveness of these grouping techniques in capturing and distinguishing students’ diverse learning patterns. Through a comprehensive analysis of ten methodologies used to cluster students in traditional programming courses and programming MOOCs, we aim to reveal how students from different cohorts exhibit varying learning behaviors and outcomes. By examining diverse models of student learning, we assess whether students in distinct groups indeed demonstrate discernible disparities in their educational journeys. Our meticulous data analysis uncovers compelling insights that challenge the notion of predefined student stereotypes and their practical utility within group-based adaptation settings. This research contributes to the discourse on student grouping by highlighting the limitations of traditional categorizations and introducing innovative approaches to understanding student diversity and tailoring educational interventions accordingly. By transcending simplistic generalizations, we strive to foster a nuanced understanding of students’ individual strengths, challenges, and potentials, promoting inclusive and effective educational practices.

Management and restoration of mangrove forests to protect coasts are promoted in many countries, including Indonesia. Indonesian mangrove forests are actively restored and managed by local communities for their ecosystem services, including coastal protection. Whether community-based mangrove management (CBMM) is effective is still debated. Our study analysed the effectiveness of different CBMM practices in four Central Javan communities by analysing the capacity of their mangrove forests to protect against coastal hazards. We used complementary interviews, field assessments and literature reviews to collect the necessary information. The overall CBMM performance and success significantly differed for each community's mangrove rehabilitation effort and the resulting coastal protection service. Of the four communities, Bedono performed best in terms of mangrove coverage, forest structure and restored coastal protection service. This is explained by multiple factors, such as application of long-term and integrated CBMM approaches, involving appropriate maintenance and additional measures to reduce wave energy. Our results can help governments, practitioners and communities to better understand the factors that contribute to CBMM's success and failure when restoring and managing mangrove forests and protecting coasts.

Security vulnerability fixes could be a promising research avenue for Automated Program Repair (APR) techniques. In recent years, APR tools have been thoroughly developed for fixing generic bugs. However, the area is still relatively unexplored when it comes to fixing security bugs or vulnerabilities. In this paper, we evaluate nine state-of-the-art APR tools and one vulnerability-specific repair tool. In particular, we investigate their ability to generate patches for 79 real-world Java vulnerabilities in the Vul4J dataset, as well as the level of trustworthiness of these patches. We evaluate the tools with respect to their ability to generate security patches that are (i) testable, (ii) having the positive effect of closing the vulnerability, and (iii) not having side effects from a functional point of view. Our results show that the evaluated APR tools were able to generate testable patches for around 20% of the considered vulnerabilities. On average, nearly 73% of the testable patches indeed eliminate the vulnerabilities, but only 44% of them could actually fix security bugs while maintaining the functionalities. To understand the root cause of this phenomenon, we conduct a detailed comparative study of the general bug fix patterns in Defect4J and the vulnerability fix patterns in ExtraVul (which we extend from Vul4J). Our investigation shows that, although security patches are short in terms of lines of code, they contain unique characteristics in their fix patterns compared to general bugs. For example, many security fixes require adding method calls. These method calls contain specific input validation-related keywords, such as encode, normalize, and trim. In this regard, our study suggests that additional repair patterns should be implemented for existing APR tools to fix more types of security vulnerabilities.

En los últimos años, la monitorización de la ubicación de personas se ha vuelto cada vez más importante en nuestra sociedad. Desde que comenzó esta práctica en los centros penitenciarios, se ha ido ampliando a otros campos, en muchos de ellos debido a la reciente pandemia. Son muchos los dispositivos que se han fabricado con el fin de controlar estas situaciones, todos ellos con una gran robustez para evitar su manipulación surgiendo así un gran problema. El estigma que produce a las personas portar este tipo de dispositivos. Este proyecto, debido al auge que están teniendo en la actualidad los relojes inteligentes y la normalidad de su uso en esta sociedad, propone el desarrollo de una aplicación para este tipo de dispositivos que solucione este problema. Esta aplicación permite monitorizar la ubicación de la persona que porta el reloj, así como detectar su retirada del cuerpo y poder realizar un aviso al centro de control en el caso de que se produzca una situación de emergencia., In recent years, monitoring the location of people has become more important in our society. Since this practice began in prisions, it has been included in other fields, in many of them due to the recent pandemic. There are many devices that have been manufactured in order to control these situations, all of them with great robustness to avoid their manipulation, thus arising a great problem. The stigma that people carry this type of devices produces. This project, due to the boom that smartwatches are currently having and the normality of their use in this society, proposes the development of an application for this type of device that solves this problem.

[Resumen]: Las páginas web actuales necesitan procesar una gran cantidad de datos y métricas cuando realizan reportes personalizados, o cuando tienen que generar tablas muy amplias. Estas cuestiones son las que intenta abordar este trabajo de fin de grado, con el desarrollo de un microservicio que intervenga como intermediario entre las consultas a la base de datos y la visualización del usuario. Para ello se diseñará una aplicación con Java/Spring Boot, capaz de preprocesar los datos y de generar reportes personalizados, que se almacenaran en archivos JSON o CSV. Además de que los informes se tendrán que generar de forma asíncrona, también será necesario que los reportes ya generados se actualicen periódicamente si existieran nuevos datos o métricas en la base de datos. Las operaciones de procesado con las que contará el sistema serán: distintos orígenes de datos, filtrado según los valores de las propiedades, filtrado por fechas, selección de las propiedades de los objetos, ordenación de los objetos por una propiedad, incorporación de títulos a los objetos y ordenación de las propiedades dentro de los objetos., [Abstract]: Today’s websites need to process a large amount of data and metrics when building customised reports, or when they need to generate very large tables. These are the issues that this final degree thesis aims to address, with the development of a microservice that acts as an intermediary between database queries and the user’s visualisation. To this end, a Java/Spring Boot application will be designed, capable of pre-processing the data and generating customised reports, which will be stored in JSON or CSV files. In addition to the fact that the reports will have to be generated asynchronously, it will also be necessary for the reports already generated to be updated periodically if there are new data or metrics in the database. The processing operations available to the system will be: different data sources, filtering by property values, filtering by date, selection of object properties, sorting objects by a property, adding titles to objects, and sorting properties within objects.

[Resumo]: Os datos ráster son unha matriz de puntos ordenados en filas e columnas onde cada punto representa información dun lugar en concreto. Este tipo de datos son moi útiles en fotografías aéreas para determinar a elevación de zonas, calcular a temperatura, humidade etc… Con todo, o seu tamaño é moi elevado e polo tanto traballar con eles complícase. Para solucionalo existen métodos como o k2-raster, que é unha estrutura de datos compacta que comprime o ráster e realiza as consultas sobre os datos de forma eficiente. O obxectivo principal deste traballo de fin de grao é desenvolver unha aplicación web que permita a subida de datos rasters, comprimíndoos nun k2-raster e permitindo a consulta para poder traballar con eles de forma eficiente, ademais de poder visualizar ditas consultas no mapa e xerar informes sobre os resultados. Para logralo, comezouse cunha análise inicial que indicou os requisitos funcionais do sistema e o seu alcance. Acto seguido iniciou o proceso de elaborar os prototipos das pantallas e para rematar a implementación dos requisitos e as probas. Utilizáronse diferentes tecnoloxías como MySQL para o almacenamento de datos, Java e Spring para o servizo REST, React para a elaboración do frontend e a librería de Leaflet para amosar os datos no mapa. Por outro lado foi preciso usar o JNI de Java, xa que a librería do k2-raster está programada en C++ e polo tanto era necesario comunicar ambas linguaxes. Finalmente, seguiuse unha metodoloxía iterativa e incremental baseada en SCRUM para a realización do traballo., [Abstract]: Raster data consists of a matrix of points arranged in columns and rows where each point represents information about a specific location. This type of data is useful in aerial photography to determine elevations, calculate temperatures, humidity, etc… Nevertheless, its size it’s too big, what makes it complicated to work with them. To solve this there are methods like k2-raster, which is a compact data structure that compress data and makes efficient queries about them. The main objective of this work is to develop a web application that allows the upload of raster data, compressing it in a k2-raster and allowing to make queries to be able to work with them in an efficient way, also being able to visualize those queries on the map and generate reports about the results. To achieve this, it began with an initial analysis that indicated the functional requirement specifications of the system and its scope. Following that, the process of making mock-ups started, and to finish, the implementation of the requirements testing. Several technologies were used, like MySQL for data storaging, Java and Spring for REST service, React for the elaboration of frontend and the Leaflet library to display the data on the map. On the other hand, it was necessary to use Java’s JNI, as the k2-raster library is programed in C++ and therefore it communicates both languages. Finally, an iterative and incremental methodology based on SCRUM was followed for the completion of the work.

The final degree project was managed using an iterative and incremental methodology for software development.

[Resumen]: El objetivo de este trabajo de fin de grado es el desarrollo de una aplicación web que permita recopilar, organizar y, finalmente, mostrar al usuario final todo tipo de datos e información sobre videojuegos. El sistema permitirá a cualquier usuario la consulta de información de los distintos videojuegos, ya sea mediante búsquedas individuales o mediante apartados específicos que el usuario conseguirá utilizando diferentes filtros dentro de la propia aplicación. Cada título posee diferente información adicional a la consultada, como pueden ser la fecha de lanzamiento, el desarrollador o el publicador de la obra. A los usuarios registrados se les permitirá poder crear y gestionar su propia colección de videojuegos, pudiendo establecer su relación actual con la obra (si ya la ha terminado, está pendiente de ello, todavía no lo ha jugado etc) así como dejar su propia valoración personal en cada uno de los títulos. La lógica de negocio estará almacenada dentro del backend de la aplicación y consistirá en una API REST implementada utilizando tecnologías Java, junto con el framework Spring Boot y MySQL para la persistencia de datos. Por otro lado, el frontend de la aplicación utilizará JavaScript junto a la ayuda de librerías como React o Redux para así llegar al desarrollo de una aplicación web Single Page Application., [Abstract]: The goal of this degree project is the development of a web application that allows the collection, organization, and ultimately, the display of all kinds of data and information about video games to the end user. The system will enable any user to access information about different video games, either through individual searches or through specific sections that the user can access using different filters within the application itself. Each title has additional information beyond what is displayed, such as the release date, developer, or publisher of the game. Registered users will be able to create and manage their own collection of video games, establishing their current relationship with each game (whether they have finished it, are in progress, or have not played it yet), as well as leaving their own personal rating for each title. The business logic will be stored in the backend of the application and will consist of a REST API implemented using Java technologies, along with the Spring Boot framework and MySQL for data persistence. On the other hand, the frontend of the application will use JavaScript along with libraries such as React and Redux, in order to develop a Single Page Application.

[Resumen]: Actualmente, existen múltiples aplicaciones que permiten encontrar en ellas bienes y/o servicios ofrecidos por distintas compañías. Este tipo de aplicaciones suelen ser bastante populares, ya que agrupan en un único sitio una amplia variedad de ofertas, lo cual las hace muy atractivas y convenientes al usuario final. Estas también resultan ventajosas para las empresas que ofrecen sus bienes y/o servicios a través de ellas, pues no tienen que asumir los costes que implica desarrollar una plataforma propia y el posterior mantenimiento de la misma. El objetivo del presente Trabajo de Fin de Grado es desarrollar una plataforma que posibilite a los locales de ocio nocturno vender sus entradas de forma ágil y sencilla, y permita a los consumidores adquirir dichas entradas de manera cómoda. La plataforma consiste en tres aplicaciones. La primera de ellas es una aplicación web administrativa implementada en JavaScript y React. El objetivo de esta, es permitir, entre otras cosas, la publicación de entradas por parte de los locales de ocio nocturno. La segunda, también destinada a los locales, es una aplicación nativa para iOS, desarrollada usando Swift y SwiftUI, cuyo propósito es permitir el escaneo de las entradas compradas por los clientes. La última aplicación (también para iOS) está destinada a los usuarios consumidores, en ella los clientes podrán adquirir las entradas puestas a la venta y tenerlas siempre disponibles. Estas tres aplicaciones se comunicarán con un backend desarrollado empleando Java, Spring Boot e Hibernate., [Abstract]: Currently, there are multiple applications that allow people to find goods and/or services offered by different companies. These types of applications are usually quite popular, since they bring together a wide variety of offers in a single place, which makes them very attractive and convenient for the end user. These are also advantageous for companies that offer their goods and/or services through them, since they do not have to assume the costs of developing their own platform and its subsequent maintenance. The objective of this End of Degree Project is to develop a platform that would enable nightlife venues to sell their tickets in an agile and simple way, and that would allow consumers to buy those tickets easily. The platform consists of three applications. The first of these is an administrative web application implemented in JavaScript and React. The purpose of this application is to allow, among other things, the publication of tickets by nightlife venues. The second, also intended for the venues, is a native iOS app, developed using Swift and SwiftUI, whose purpose is to allow the scanning of tickets purchased by the customers. The last app (also for iOS) is intended for the end users, in it, customers will be able to buy the tickets put up for sale and have them always available. These three applications will communicate with a backend developed using Java, Spring Boot and Hibernate.

[Resumen]: A lo largo del territorio español existen diversas agrupaciones de personas, que se organizan con el fin de adoptar unos hábitos de consumo, conscientes y responsables con el medio ambiente. Un ejemplo de estos grupos es Zocamiñoca en A Coruña, una cooperativa de consumo responsable, sin ánimo de lucro y con unos valores sociales y medioambientales bien definidos. Siendo este el carácter de la de organización, los recursos económicos destinados tanto a infraestructura, como a herramientas informáticas son muy limitados. Por esto, en las comunicaciones entre las distintas partes, así como en los procedimientos seguidos en el desempeño de su actividad, tienden a adaptar herramientas destinadas a otros fines o a recurrir a mecanismos más tradicionales, haciendo estos procesos poco eficientes y propensos a errores. En este trabajo se presentará un análisis en profundidad del funcionamiento de Zocamiñoca y sus oportunidades de mejora, para luego diseñar e implementar una solución de comunicación adaptada a la cooperativa, en un intento de mejorar su funcionamiento cotidiano., [Abstract]: Throughout the Spanish territory, there are various groups of people, who organize themselves in order to adopt conscientious and responsible consumption habits towards the environment. An example of these groups is Zocamiñoca in A Coruña, a responsible consumption cooperative, nonprofit, and with well-defined social and environmental values. Given the nature of this organization, the financial resources allocated to both infrastructure and computer tools, are very limited. Because of this, in communications between parties, as well as in the procedures followed in their activities, they tend to adapt tolls meant for other purposes or resort to more traditional methods, making these processes inefficient and prone to errors. This work will present an in-depth analysis of Zocamiñoca’s functioning and its opportunities for improvement, and subsequently, design and implement a solution tailored to the cooperative in an attempt to enhance its daily work.

Una vez definidos los puntos anteriores se procedió a elaborar un diseño más detallado de la aplicación y una planificación del proyecto, seguidos de la implementación y pruebas del producto final. En el desarrollo se empleó el lenguaje Java junto con el framework de Spring para la implementación del backend web y la API REST que utilizará para acceder a sus funcionalidades. Para la persistencia de datos se utiliza el SGBD PostgreSQL, utilizado para la gestión de una base de datos relacional, y sobre el cual se utiliza el framework ORM Hibernate. Y para el desarrollo del frontend se utilizó el framework de JavaScript, Vue.js. El trabajo de fin de grado se gestionó siguiendo una metodología ágil, iterativa e incremental para el desarrollo de software como es Scrum., [Abstract]: The objective of this end-of-degree project is to develop a web application that allows the management of end-of-degree or master’s projects and helps directors to carry out and direct such projects. For this, it was necessary to perform a previous analysis to determine the scope, the possible technologies to be used in this project and the methodology that the projects that will be managed in the application will follow. Once the previous points were defined, a more detailed design of the application and a planning of the project were elaborated, followed by the implementation and tests of the final product. During development, the Java language was used together with the Spring framework for the implementation of the web backend and the REST API that will be used to access its functionalities. For data persistence, the PostgreSQL DBMS is used, used for the management of a relational database, and on which the Hibernate ORM framework is used. And for the development of the frontend, the JavaScript framework, Vue.js, was used.

[Resumen]: En la actualidad, para tener una salud financiera adecuada, es importante tener cierto control sobre dónde y en qué se gasta el dinero. Además algunas compras se repiten de forma periódica, y es interesante tener conocimiento sobre sus precios anteriores para decidir compras futuras. Para intentar dar solución a estas problemáticas, en este trabajo de fin de grado se diseña e implementa una aplicación móvil mediante tecnologías Java / Javascript que facilite la gestión de gastos personales. En particular, permite al usuario anotar todos sus gastos e ingresos dividiéndolos en categorías y mediante su procesado, recuperar una serie de estadísticas que el usuario pueda analizar. A mayores se da la opción de configurar movimientos recurrentes que se formalicen con la periodicidad elegida por el usuario, y la exportación de los mismos a Google Calendar. También da la opción de agrupar gastos e ingresos en el momento de su creación en eventos, de los cuales también se pueden recuperar estadísticas. Por otro lado, permite el seguimiento de precios a lo largo del tiempo de productos personalizados de manera manual, y consultar información sobre la evolución de los mismos y sus máximos y mínimos. Los precios de estos productos pueden asociarse a tiendas y filtrar la información recuperada de un producto por dichas tiendas., [Abstract]: Actually, in order to have adequate financial health, it is important to have some control over where and how much money is spent on. Some purchases are repeated periodically, and it is interesting to know about their previous prices to decide future purchases. To try to solve these problems, this final degree project will design and implement a mobile application using Java / Javascript technologies. The application will allow access through the Google login or by registering as a local user of the system that facilitates the management of personal expenses. In particular, it allows the user to write down all their expenses and income, dividing them into categories and, through their processing, recover a series of statistics that the user can analyze. In addition, there is the option of configuring recurring movements that are formalized with the periodicity chosen by the user and exporting them to Google Calendar. There is also the option of grouping expenses and income at the time of its creation into events from which statistics can also be retrieved. On the other hand, it allows the manually monitoring of prices over time of personalized products and consult information on their evolution and their maximus and minimous.The prices of these products can be associated with stores and filter the information retrieved for a product by those stores.

The authors want to thank the Ministry of Economy and Competitiveness of Spain for the support received from grants DPI2009-14552-C02 and DPI2007-61068., This paper describes the design and implementation of a virtual and remote laboratory based on Easy Java Simulations (EJS) and LabVIEW. The main application of this laboratory is to improve the study of sensors in Mobile Robotics, dealing with the problems that arise on the real world experiments. This laboratory allows the user to work from their homes, tele-operating a real robot that takes measurements from its sensors in order to obtain a map of its environment. In addition, the application allows interacting with a robot simulation (virtual laboratory) or with a real robot (remote laboratory), with the same simple and intuitive graphical user interface in EJS. Thus, students can develop signal processing and control algorithms for the robot in simulation and then deploy them on the real robot for testing purposes.

Los dispositivos wearables están cada vez más presentes en el día a día. Relojes, pulseras, auriculares o gafas son ya parte de nuestras vidas y nos ofrecen una mayor comodidad en distintos aspectos de nuestras vidas. Uno de ellos, y quizá el más importante, es la salud. Con ellos se pueden medir diferentes parámetros biométricos y llevar un registro de ellos. Además, determinadas patologías pueden incluso ser detectadas de manera precoz con bastante fiabilidad. En este TFG se pretende crear una aplicación para smartwatches Wear OS, que sea capaz de monitorizar la frecuencia cardiaca en estado de reposo. Además, se podrá transmitir dicha medición al teléfono para llevar un registro de ello y algunas funcionalidades más, presentes todas ellas en una aplicación Android para smartphones. Con ello se pretende explorar estas nuevas tecnologías e integrar en el proyecto los componentes básicos de toda aplicación Wear OS., Grado en Ingeniería Informática de Servicios y Aplicaciones

The Maven Central Repository hosts over 11 million packages. As Maven itself is a build tool for Java, the majority of these packages are Java archives. This research aims to analyze these packages and look into various build aspects of these projects (the research questions): are Java modules used, what Java versions are used and how is the compiler configured? This is done by downloading a subset of these packages and looking at both the final artifact and the attached Project Object Model (Maven configuration). Specifically, one version is randomly selected from each distinct package hosted on Maven Central and then analyzed. This research helps inform Java language developers and library maintainers. It captures parts of the build system evolution over a span of more than a decade. Precisely, version adoption, reproducibility and desirable build features are all important metrics for project maintainers in any software ecosystem. In the end, 473352 packages were analyzed. Firstly, it was found that Java modules are rare: only 6919 (1.69% of the artifacts with an archive) of the packages use Java modules. Secondly, the most common Java version used is Java SE 8 (182476 packages) representing almost half of all analyzed packages. All long-term support versions (Java SE 8, 11, 17 and 21) make up roughly half of the available packages. Thirdly, only 54.98% of artifacts configure the Maven compiler plugin with the most used parameters being the source and target Java versions. The most common additional compiler flags are verbosity settings, providing more feedback and code analysis from both the linter and compiler., CSE3000 Research Project, Computer Science and Engineering

Ever since the concept of the Internet was born, it has experienced a massive increase in the number of users. Similarly, there has been an exponential increase in the amount of information that they transmit, partly because of new technologies and services that have emerged, such as cloud and real-time communication. Customers do now demand a fast and reliable interaction, without any data loss or undesired delays. In order to meet these needs and keep up with the constantly-evolving technologies different non-profit organizations needed to devise a new technology, and this is when Software-Defined Networking (SDN) was born. Unlike traditional networks to date, it decouples the control layer from the data layer, leaving the act of forwarding traffic to the network device and delegating all network decisions to a controller, thus centralizing all the decisions, which improves network operability and agility. Despite all the improvements made with this technology, we still encounter the same problems of traditional networks regarding traffic routing. Conventional algorithms such as Dijkstra and Least Loaded (LL) based on the occupancy of the links, allocate traffic without considering the impact the chosen path could have if future traffic were to be introduced in the network. The objective of this project is to create an algorithm capable of routing traffic taking into account the future impact. To evaluate the proposed mechanism of Dijkstra, we will first obtain some experimental results using the default link weights and then base these weights on the occupancy of the links, using the Open Network Operating System (ONOS) as the SDN controller and the Multi-Generator (MGEN) tool to generate traffic. After these results, this research will use Reinforcement Learning (RL), a subcategory of Artificial Intelligence (AI), to train a RL model in Python using a network of eight interconnected switches. After the agent is trained, we have made a comparison between RL, LL

Over the past few years there has been vast development in Android Application technology. This development made people's lifestyle much easier and interesting through various innovations by finding solutions to day-to-day problems. Even though many things became easier, still shopping is tough. For customers finding the required product in the supermarket is the most challenging task and moreover it is exhausting to stand in long queues at the billing counters. Shopping is a day-to-day activity. Many people visit supermarket for shopping on regular basis and during weekends, holidays and festive season supermarkets witness huge crowds. The development of online shopping websites has attracted people to purchase products online without visiting any supermarket. Mostly all the products are available on websites like Amazon, Flipkart, etc. But people cannot verify the quality of the product physically and can only verify after the product’s delivery. If the product is not up to the customer’s expectations, then it becomes a hefty task of returning and reordering the product.

In recent years, artificial intelligence (AI) has become increasingly popular. An area where AI technology is used and has received much attention during the past year is chatbots. They can simulate an understanding of human language and form text responses to questions asked. Apart from generating text responses, they can also generate programming code, making them useful for tasks such as testing. Although testing is considered a crucial part of software development, many find it tedious and time-consuming. There are currently limited AI-powered tools for generating unit tests in general and even fewer for the programming language Java. The thesis tackles the problem of the lack of tools for generating unit tests in Java that explore the capabilities of AI, and a research question is introduced thereafter. The purpose of this thesis is to address the issue by creating a prototype for generating unit tests in Java based on the AI model, GPT-3.5-Turbo. The goal is to provide a basis for other professionals to create tools for generating unit tests, which was done by experimenting with different prompts and values of a randomness parameter and then suggesting the prototype JUTAI. A quantitative research method with an experimental and comparative approach was used to evaluate the results. A comparison model with three criteria was brought forward to evaluate the results. The findings reveal that JUTAI outperformed the general-purpose AI tool, ChatGPT, across all three criteria and indicate that the goal of this thesis is achieved and the research question answered., Intresset för artificiell intelligens (AI) har ökat de senaste åren. Ett område där AI- teknologi används och som har fått mycket uppmärksamhet under det senaste året är chattbottar. De kan simulera en förståelse för mänskligt språk och svara på frågor i textformat. Utöver det kan de även generera programkod. Tack vare förmågan att generera kod kan de användas för testning. Även om testning anses vara en viktig del av mjukvaruutveckling, tycker många att det är tråkigt och tidskrävande. För närvarande finns det ett begränsat antal verktyg som kan generera enhetstester, och det finns ännu färre verktyg som kan göra detta i Java. Detta examensarbete tog sig an problemet med bristen på AI-verktyg för enhetstestning i Java genom att besvara på forskningsfrågan som ställdes. Syftet med examensarbetet är att föreslå en lösning på problemet genom att utveckla en prototyp som använder sig av AI- modellen GPT-3.5-Turbo för att generera enhetstester i Java. Målet är att ge en grund för andra yrkesverksamma att skapa verktyg för att generera enhetstester, vilket gjordes genom att experimentera med olika instruktionstrukturer och värden för en slumpmässighetsparameter, och sedan föreslå protypen JUTAI. En kvantitativ forskningsmetod tillsammans med en experimentell och jämförande ansats användes för att utvärdera resultaten. En jämförelsemodell med tre kriterier togs fram för att utvärdera resultaten. Resultaten visar att JUTAI presterade bättre än AI-verktyget ChatGPT i de tre kriterierna och indikerar att målet med detta examensarbete uppnåddes och forskningsfrågan besvarades.

Syftet med denna studie var att utveckla en generell applikation som kan generera DDL-skript från tre olika databaser: Oracle, SQL Server och DB2, genom att enbart använda en JDBC-uppkoppling. Behovet av denna studie kommer från att databasadministratörer och utvecklare effektivt ska kunna hantera databaser med olika system med varierande syntax och struktur. Processen genomfördes i IDEAn IntelliJ med java.sql-APIt för databasoperationer. Resultatet visade att trots skillnaderna mellan dessa databaser var det möjligt att utveckla en generell process för att extrahera DDL-kod med endast en JDBCuppkoppling. Dock krävdes vissa specifika anpassningar för varje databassystem. En observation var hanteringen av primärnycklar och index mellan systemen. Denna applikation har potential att vidareutvecklas till ett kraftfullt verktyg för databashantering, vilket sparar tid och resurser. Områden för framtida undersökning inkluderar hantering av komplexa datatyper och strukturer, samt prestanda med stora databaser., This study was aimed at developing a generic application capable of generating DDL-code from three different databases: Oracle, SQL Server and DB2 by using JDBC. This research necessity origins from database administrators and developers need to effectively manage databases across different systems with different syntax and structure. The process was conducted in the IDEA IntelliJ using the java.sql-API for database operations. The result showed that despite the differences between these databases it was possible to develop a generic process for extracting DDL-code only using a JDBC connection. However, some specific adaptions were required for each database system. An observation was the managing of primary keys and indexes across the systems. This application has the potential to be developed further into a powerful tool for database management that saves time and resources. Areas for further investigation is handling of complex data types and structures and performance with large databases.

This bachelor thesis presents a comparison of three Java testing frameworks - JUnit 5,TestNG and Spock - with the purpose of evaluating their suitability in testing RESTAPIs built with Spring Boot. As the demand for reliable and high-quality softwaresystems continues to grow, automated testing techniques are crucial in ensuring thecorrect functionality of applications. Our study aims to fill the knowledge gap in thecurrent literature by focusing on unit tests for Java REST APIs running on the Springframework.We developed a single Spring Boot application and applied tests written using thethree selected testing frameworks. We then compared the performance of the frame-works based on execution time, memory usage and code conciseness. Additionally,we conducted a questionnaire to gather developer preferences for the frameworks.Our findings reveal that TestNG outperforms JUnit 5 in terms of performance, whileSpock requires fewer characters, making it more concise. However, JUnit 5 remainsthe most well-known and widely used testing framework among developers. Theresults of our study provide valuable insights into the performance and developerpreferences of the selected testing frameworks.

I dagsläget står mobila enheter för strax under 55 procent av den globala marknaden jämfört med datorer och surfplattor. Android och iOS är de två stora operativsystemen för mobila enheter, där Android har cirka 70 procent av marknaden. Applikationer till dessa två operativsystem kan utvecklas var för sig. För att utveckla applikationer som kan köras på både Android och iOS kan ett crossplatform-ramverk användas. Detta kan leda till kostnadsbesparingar och tidseffektivisering, men också till sämre prestanda. Denna komparativa studie genomfördes i samarbete med AFRY och syftar till att jämföra crossplatform-ramverken .NET MAUI och React Native mot varandra, men också mot en nativ applikation utvecklad i Java till Android. Jämförelsen gjordes ur ett prestandaperspektiv. De prestandakriterier som har jämförts är applikationernas storlek, uppstarts- och exekveringstid samt CPU- och RAM-användning. Tre applikationer utvecklades, med likvärdig funktionalitet, för att möjliggöra jämförelse. Funktionaliteten bestod av en tung beräkning i form av Fibonaccisekvensen, användande av GPS-sensorn, anrop till ett REST-API samt filhantering. För att samla in data till denna studie användes verktygen Android Profiler, Logcat samt egen implementerad kod. Resultaten visar att React Native exekverar snabbare, har en lägre resursanvändning och blir mindre i storlek i de flesta fall jämfört med .NET MAUI. .NET MAUI hanterar dock större beräkningar snabbare och mer resurssnålt. Resultatet visar även att en nativ applikation för Android presterar bättre i de flesta fall och är att rekommendera om prestanda är viktigare än utvecklingskostnad och tidsåtgång.

På substratenheten på Karolinska Universitetssjukhuset inventerades och produktionsplanerades allt för hand på papper 3 gånger i veckan. Syftet med projektet har varit att hitta en digital lösning för att effektivisera arbetet kopplat till inventeringen och produktionsplaneringen. Målet har därför varit att utveckla en skrivbordsapplikation för att uppnå detta syfte genom avläsning av QR-koder. Projektet genomfördes genom programmering i språket Java och utnyttjade JavaFX för alla grafiska komponenter. Databaskopplingen som krävdes använde mySQL för att sammankoppla program med databas. För utvecklandet av applikationen så har designmönstret Model-View-Controller använts. Vi som författare anser att applikationen bör bearbetas vidare, detta då en del funktionalitet skulle behöva optimeras och även utvecklas vidare för att uppnå önskad användarvänlighet. Dock är vår slutsats att alla de uppsatta målen uppfylldes., At the substrate unit at Karolinska University Hospital they previously did their inventory and production planning by hand three times a week. The purpose of the project has been to find a digital solution to streamline this unit’s workload connected to inventory and production planning. Therefore, the aim of the project was to develop a desktop application to fulfill the purpose of the project by scanning QR-codes. The project has been performed through programming in the language Java and used the JavaFX library for all graphical components. The database connection used mySQL to connect the program to the database. For the development of the application the design-pattern Model-View-Controller were used. As authors of the report, we consider that the application should be further optimized, and additional functions should be introduced in order to achieve greater usability. However, our conclusion is that the application fulfills the aims set at the beginning of the project.

Böjsenor är senor i fingrarna som är kopplade till underarmens muskler. De läker långsamt efter en skada och kan därför gå av efter en reparation om patienten tränar för mycket eller för tungt. Vid för lite träning fastnar senan i omgivande vävnad och fingret blir stelt. Rehabiliteringen efter en böjsenskada pågår under minst tre månader efter operationen. Det kan därför bli svårt för patienter att upprätthålla motivationen och följa alla instruktioner korrekt under hela denna tid. Syftet med projektet var att skapa en mobilapplikation som stödjer patienter i deras rehabilitering av en böjsenskada samt att implementera ett digitalt vinkelmätningsverktyg i applikationen. Applikationen utvecklades för både iOS- och Android-enheter med hjälp av deras officiella utvecklingsmiljöer, Android Studio och Xcode. Några funktioner som applikationen består av är en kalender med översikt av träningsplanen, möjligheten att utvärdera pass, möjligheten att skapa träningsprogram och exportera träningsdata. Applikationen innehåller även information om träningsinnehållet, kontaktinformation och allmänna råd till patienten. Innan applikationen kan publiceras måste den testas på patienter för att få återkoppling om användarvänlighet och funktionalitet. De önskade funktionerna från uppdragsgivaren och målen uppnåddes med undantag av funktionen att lägga till möten som prioriterades bort. Det digitala vinkelmätningsverktyget implementerades för Android men inte för iOS., Flexor tendons are tendons in the fingers that are connected to the muscles in the forearm. They heal slowly after an injury and can rupture again after the repair if the patient exercises too much or lifts too heavy. Insufficient exercise can cause the tendon to adhere to surrounding tissue, resulting in finger stiffness. Rehabilitation following a flexor tendon injury typically lasts for at least three months after surgery. Therefore, patients may find it challenging to maintain motivation and follow all instructions correctly throughout this period. The purpose of this project was to develop a mobile application that supports patients in their rehabilitation of a flexor tendon injury along with the implementation of a digital angle measuring tool. The application was developed for both iOS and Android devices using their official integrated development environments, Android Studio and Xcode. Some features that the application consists of are a calendar providing an overview of the training plan, the ability to evaluate sessions, the ability to create custom training programs and export training data. Additionally, the application contains information about the training content, contact details, and general advice for the patient. Before the application can be published, it needs to be tested on patients to gather feedback on user-friendliness and functionality. The desired features from the client and the goals for the project were achieved, apart from the meeting scheduling feature, which was deprioritized. The digital angle measuring tool was implemented for Android but not for iOS.

Denna studie fokuserar på att jämföra responstiden för API:er skapade med Laravel och Spring Boot inom flygresebranschen för att förbättra användarupplevelsen och minska risken för kundförlust. REST-standarden, som använder HTTP-metoderna GET, PUT, DELETE och POST för att hantera resurser, är en viktig del av webbutveckling. Trots detfinns det en brist på studier som jämför dessa två ramverk när det gäller responstid. Genom att utveckla fyra REST-API:er, en databas och ett testverktyg analyseras responstid och testas hypotesen i examensarbetet. Resultaten visar att Spring-Boot erbjuder en stabil och kortare responstid jämfört med Laravel för både GET- och POST-request. Framtida forskning kan utvidga studien till att inkludera andra populära API-ramverk för att ge en mer omfattande förståelse av API-ramverkslandskapet och underlätta val av ramverk baserat på specifika projektbehov.

Mikrotjänstarkitektur är den senaste trenden inom mjukvaruutveckling som gör det möjligt att bygga komplexa system från mindre tjänster utformade för att vara självförsörjande och fokuserade på en specifik affärsfunktionalitet. Dessa kan utvecklas, testas, driftsättas och skalas oberoende av varandra, vilket gör att team kan vara mer autonoma och leverera värde till kunder snabbare. Bolagsverket är i processen att övergå till en arkitektur baserad på mikrotjänster men dess långa historia av omfattande end-to-end-tester som är komplexa att sätta upp, långsamma att köra och kräver mycket resurser gör det svårt att testa att integrationerna fortsätter att fungera efter att ändringar har införts. Contract testing underlättar denna verifiering. Studien implementerar Consumer-Driven förhållningssättet till tekniken med ramverken Pact och Spring Cloud Contract med syftet att undersöka hur integrationen mellan två tjänster som kommunicerar via ett REST API kan testas isolerat, samtidigt som man säkerställer att de kommer att fortsätta att interagera som förväntas när den faktiska integrationen testas. De kvantitativa och kvalitativa resultaten från fem semistrukturerade intervjuer visar att Bolagsverket i genomsnitt skulle kunna minska tiden det tar att leverera en funktion med 24 %, öka frekvensen av distribution med 42 % och minska infrastrukturkostnader med 52 %. Det här skulle göra det möjligt att ersätta end-to-end tester tidigt i utvecklingscykeln med kontraktstester och att ha en enda testmiljö med fullständiga integrationer innan driftsättning till produktion. Tekniken har emellertid vissa inneboende kostnader och garanterar i sig inte alla fördelar med en mikrotjänstarkitektur, Microservices architecture are the latest trend in software development enabling to build complex systems from smaller services designed to be self-sufficient and focused on a specific business functionality. These can be developed, tested, deployed, and scaled independently, allowing teams to be more autonomous and deliver value to customers faster. The Swedish Companies Registration Office, Bolagsverket, is in the process of transitioning toward a microservices architecture but its long history of extensive reliance on end-to-end tests that are complex to set up, slow to run, and require plenty of resources makes it difficult to test that the integrations continue to work after changes are introduced. Contract testing facilitates such verification. The study implements the Consumer-Driven approach to this technique with the frameworks Pact and Spring Cloud Contract with the objective of investigating how the integration between two services communicating via a REST API can be tested in isolation, while ensuring that they will continue to interact as expected when the actual integration is tested. The quantitative and qualitative results from five semi-structured interviews show that, on average, the agency could decrease the time it takes to deliver a feature by 24%, increase the deployment frequency by 42%, and reduce infrastructural expenses by 52%. This would allow to replace end-toend tests early in the development cycle with contract tests, and to have a sole test environment with complete integrations before deploying to production. However, the technique has some inherent costs and on its own does not guarantee all the benefits of a microservices architecture

Datorspel behöver utnyttja hårdvara effektivt för att kunna vara tillgänglig på så många system som möjligt med varierande kapacitet. En viktig del i detta är att optimera användandet av processorns cacheminnen. Programmerare kan följa en dataorienterad design för att implementera cacheeffektiv kod. Detta förutsätter att programmeraren har kontroll över hur data lagras i minnet, vilket är svårt att uppnå i Java. Project Valhalla kan erbjuda funktioner för att åtgärda detta problem. I detta arbete jämfördes objektorienterad design med dataorienterad design i språken C++, Java och den pågående utvecklingen av Project Valhalla. En prototyp utvecklades och implementerades med olika kombinationer av dessa språk och designer. För varje implementation mättes prestanda och cacheeffektivitet. Resultatet visade att Java med Project Valhalla kan uppnå liknande prestanda som C++ vid dataorienterade implementationer. På grund av vissa begränsningar i Valhallas funktioner kommer det troligtvis inte bli ett praktiskt alternativ till lågnivåspråk inom en snar framtid., Computer games need to utilize hardware efficiently in order to be available on as many systems as possible with varying capabilities. An important part of this is to optimize the use of the CPU’s cache. A programmer can follow a data-oriented design to implement cache-efficient code. This requires the programmer to have control over how data is stored in memory, which is difficult to achieve in Java. Project Valhalla may offer features to address this issue. In this thesis, object-oriented design was compared with data-oriented design in the languages C++, Java, and the ongoing development of Project Valhalla. A prototype was developed and implemented using different combinations of these languages and designs. For each implementation, performance and cache efficiency were measured. The result showed that Java with Project Valhalla can achieve similar performance to C++ in data-oriented implementations. Due to some limitations in Valhalla's features, it is unlikely that it will become a suitable alternative to low-level languages anytime soon.

To develop a high performant web service in Java, Reactive WebFlux has previously been utilized as the only alternative. With the introduction of virtual threads in Java 19, it has been considered that it would be an alternative to the current provided option. This paper presents the performance difference between Spring applications powered by normal threads, virtual threads, and its reactive counterpart Reactive WebFlux. The tests were done by creating three prototypes, which were used to call an endpoint with a set delay time and increasing the number of requests per second until system failure. The results show that the virtual threaded prototypes performed slightly better than the reactive prototype. The question remains whether the Reac- tive WebFlux application using the most optimal web server produces a different re- sult, as well as future research on how virtual threads perform with database usage., För att utveckla högpresterande webbtjänster i Java har Reactive WebFlux varit det främsta alternativet. Med introduktionen av virtuella trådar i Java 19 har spekulerats kunna ersätta reaktiva webbtjänster. Detta arbete presenterar prestandaskillnaden mellan Spring-applikationer som drivs av normala trådar, virtuella trådar och dess reaktiva motsvarighet Reactive WebFlux. Testerna utfördes genom att skapa tre pro- totyper, som användes för att anropa en slutpunkt med en satt fördröjningstid och öka antalet förfrågningar per sekund fram till systemfel. Resultaten visade att proto- typen med virtuella trådar presterade något bättre än den reaktiva prototypen. Där- emot är det ännu oklart om Reactive WebFlux-applikationen med en optimal webb- server skulle producera ett annat resultat. Dessutom skulle det vara intressant för framtida forskning om hur virtuella trådar fungerar med databasanvändning.

This bachelor thesis presents a comparison of three Java testing frameworks - JUnit 5,TestNG and Spock - with the purpose of evaluating their suitability in testing RESTAPIs built with Spring Boot. As the demand for reliable and high-quality softwaresystems continues to grow, automated testing techniques are crucial in ensuring thecorrect functionality of applications. Our study aims to fill the knowledge gap in thecurrent literature by focusing on unit tests for Java REST APIs running on the Springframework.We developed a single Spring Boot application and applied tests written using thethree selected testing frameworks. We then compared the performance of the frame-works based on execution time, memory usage and code conciseness. Additionally,we conducted a questionnaire to gather developer preferences for the frameworks.Our findings reveal that TestNG outperforms JUnit 5 in terms of performance, whileSpock requires fewer characters, making it more concise. However, JUnit 5 remainsthe most well-known and widely used testing framework among developers. Theresults of our study provide valuable insights into the performance and developerpreferences of the selected testing frameworks.

Syftet med denna studie var att utveckla en generell applikation som kan generera DDL-skript från tre olika databaser: Oracle, SQL Server och DB2, genom att enbart använda en JDBC-uppkoppling. Behovet av denna studie kommer från att databasadministratörer och utvecklare effektivt ska kunna hantera databaser med olika system med varierande syntax och struktur. Processen genomfördes i IDEAn IntelliJ med java.sql-APIt för databasoperationer. Resultatet visade att trots skillnaderna mellan dessa databaser var det möjligt att utveckla en generell process för att extrahera DDL-kod med endast en JDBCuppkoppling. Dock krävdes vissa specifika anpassningar för varje databassystem. En observation var hanteringen av primärnycklar och index mellan systemen. Denna applikation har potential att vidareutvecklas till ett kraftfullt verktyg för databashantering, vilket sparar tid och resurser. Områden för framtida undersökning inkluderar hantering av komplexa datatyper och strukturer, samt prestanda med stora databaser., This study was aimed at developing a generic application capable of generating DDL-code from three different databases: Oracle, SQL Server and DB2 by using JDBC. This research necessity origins from database administrators and developers need to effectively manage databases across different systems with different syntax and structure. The process was conducted in the IDEA IntelliJ using the java.sql-API for database operations. The result showed that despite the differences between these databases it was possible to develop a generic process for extracting DDL-code only using a JDBC connection. However, some specific adaptions were required for each database system. An observation was the managing of primary keys and indexes across the systems. This application has the potential to be developed further into a powerful tool for database management that saves time and resources. Areas for further investigation is handling of complex data types and structures and performance with large databases.

I dagsläget står mobila enheter för strax under 55 procent av den globala marknaden jämfört med datorer och surfplattor. Android och iOS är de två stora operativsystemen för mobila enheter, där Android har cirka 70 procent av marknaden. Applikationer till dessa två operativsystem kan utvecklas var för sig. För att utveckla applikationer som kan köras på både Android och iOS kan ett crossplatform-ramverk användas. Detta kan leda till kostnadsbesparingar och tidseffektivisering, men också till sämre prestanda. Denna komparativa studie genomfördes i samarbete med AFRY och syftar till att jämföra crossplatform-ramverken .NET MAUI och React Native mot varandra, men också mot en nativ applikation utvecklad i Java till Android. Jämförelsen gjordes ur ett prestandaperspektiv. De prestandakriterier som har jämförts är applikationernas storlek, uppstarts- och exekveringstid samt CPU- och RAM-användning. Tre applikationer utvecklades, med likvärdig funktionalitet, för att möjliggöra jämförelse. Funktionaliteten bestod av en tung beräkning i form av Fibonaccisekvensen, användande av GPS-sensorn, anrop till ett REST-API samt filhantering. För att samla in data till denna studie användes verktygen Android Profiler, Logcat samt egen implementerad kod. Resultaten visar att React Native exekverar snabbare, har en lägre resursanvändning och blir mindre i storlek i de flesta fall jämfört med .NET MAUI. .NET MAUI hanterar dock större beräkningar snabbare och mer resurssnålt. Resultatet visar även att en nativ applikation för Android presterar bättre i de flesta fall och är att rekommendera om prestanda är viktigare än utvecklingskostnad och tidsåtgång.

Management and restoration of mangrove forests to protect coasts are promoted in many countries, including Indonesia. Indonesian mangrove forests are actively restored and managed by local communities for their ecosystem services, including coastal protection. Whether community-based mangrove management (CBMM) is effective is still debated. Our study analysed the effectiveness of different CBMM practices in four Central Javan communities by analysing the capacity of their mangrove forests to protect against coastal hazards. We used complementary interviews, field assessments and literature reviews to collect the necessary information. The overall CBMM performance and success significantly differed for each community's mangrove rehabilitation effort and the resulting coastal protection service. Of the four communities, Bedono performed best in terms of mangrove coverage, forest structure and restored coastal protection service. This is explained by multiple factors, such as application of long-term and integrated CBMM approaches, involving appropriate maintenance and additional measures to reduce wave energy. Our results can help governments, practitioners and communities to better understand the factors that contribute to CBMM's success and failure when restoring and managing mangrove forests and protecting coasts., Coastal Engineering

Over the past few years there has been vast development in Android Application technology. This development made people's lifestyle much easier and interesting through various innovations by finding solutions to day-to-day problems. Even though many things became easier, still shopping is tough. For customers finding the required product in the supermarket is the most challenging task and moreover it is exhausting to stand in long queues at the billing counters. Shopping is a day-to-day activity. Many people visit supermarket for shopping on regular basis and during weekends, holidays and festive season supermarkets witness huge crowds. The development of online shopping websites has attracted people to purchase products online without visiting any supermarket. Mostly all the products are available on websites like Amazon, Flipkart, etc. But people cannot verify the quality of the product physically and can only verify after the product’s delivery. If the product is not up to the customer’s expectations, then it becomes a hefty task of returning and reordering the product.

Plagiarism is a hot topic in modern education andscience. It requires special attention since committing plagiarismis very easy with the use of the internet. This problem can befought against utilizing prevention or detection methods, whichhave been both used in this work.
