This note builds on an earlier Warta note (Doust, 2022) that summarised the geological development of the island of Trinidad and the margins of the Caribbean Sea. Parts of Southeast Asia can be readily compared to these areas and, I believe, the two provinces can provide valuable analogues for each other. I illustrate this by considering examples of tectonic style taken from transpressional fold belts in Trinidad and eastern Java, from the evolution of foreland and wrench basin stratigraphy and from striking similarities between the stratigraphy and structure of Borneo and Trinidad’s Tertiary continent margin deltas.

U ovom radu obrađujemo temu kalibracije kamere i kako koristiti OpenCV s Javom uz pomoć Apache Mavena. Naglašavamo značaj kalibracije kamere kao ključnog koraka u obradi slike te pružamo objašnjenje jednostavnih matematičkih principa na kojima se ona temelji. Dodatno istražujemo i koncepte intrinzične i ekstrinzične matrice kamere te prikazujemo jednadžbu koja ih kombinira kako bi se uspostavio odnos između 3D točaka i projekcije slike. Također predstavljamo i Java aplikaciju koja koristi OpenCV biblioteku te na pristupačan način demonstrira proces kalibracije kamere. Analiziramo rezultate kalibracije i komentiramo njihovu implikaciju i moguće primjene. Ovaj rad pruža sveobuhvatan pregled kalibracije kamere, njenu implementaciju pomoću Jave i biblioteke OpenCV te praktičnu primjenu rezultata kalibracije. In this thesis, we cover the topic of camera calibration and how to use OpenCV with Java, facilitated by Apache Maven. We emphasize the significance of camera calibration as a crucial step in image processing, as well as explaining the simple math behind its functioning. We delve into the concepts of intrinsic and extrinsic camera matrices and illustrate the equation for combining them to establish the relationship between 3D points and image projection. Additionally, we showcase an application developed using Java and OpenCV library, which demonstrate the calibration process in an accessible manner. We examine the calibration results and provide commentary on their implications and potential applications. Overall, this thesis offers a comprehensive overview of camera calibration, its implementation using the OpenCV library in Java, and the practical implications of the calibration results.

Software testing plays a critical role in the development and the assurance of the software quality. However, the quality of the code that is responsible for testing may, itself, be affected by poor design choices, known as test smells. In the literature, test smells may be interpreted differently by developers, which in turn can lead to different detection tools and results. In our work, we have selected the mostly commonly used detection tools and have investigated their overall agreement across different projects and different test smells. The found results were evaluated according to the average level of agreement, where we observed a definite disagreement between the tools. To overcome this gap of misinterpretation, we propose in this paper a multi-label classification approach to detect test smells based on a deep representation of the test code. We conducted our experiments using 4 problem-transformation techniques and 4 ensemble techniques. To evaluate our experimental results, we built a benchmark using a tool-based approach for labelling and made it publicly available. Binary Relevance and RAkEL are found to be the best multi-label techniques that achieve high performance results.

In this paper, we propose to use production executions to improve the quality of testing for certain methods of interest for developers. These methods can be methods that are not covered by the existing test suite, or methods that are poorly tested. We devise an approach called PANKTI which monitors applications as they execute in production, and then automatically generates differential unit tests, as well as derived oracles, from the collected data. PANKTI's monitoring and generation focuses on one single programming language, Java. We evaluate it on three real-world, open-source projects: a videoconferencing system, a PDF manipulation library, and an e-commerce application. We show that PANKTI is able to generate differential unit tests by monitoring target methods in production, and that the generated tests improve the quality of the test suite of the application under consideration.

Application Programming Interfaces (APIs) allow their users to reuse existing software functionality without implementing it by themselves. However, using external functionality can come at a cost. Because developers are decoupled from the API's inner workings, they face the possibility of misunderstanding, and therefore misusing APIs. Prior research has proposed state-of-the-art example-based API misuse detectors that rely on existing API usage examples mined from existing code bases. Intuitively, without a varied dataset of API usage examples, it is challenging for the example-based API misuse detectors to differentiate between infrequent but correct API usages and API misuses. Such mistakes lead to false positives in the API misuse detection results, which was reported in a recent study as a major limitation of the state-of-the-art. To tackle this challenge, in this paper, we first undertake a qualitative study of 384 falsely detected API misuses. We find that around one third of the false-positives are due to missing alternative correct API usage examples. Based on the knowledge gained from the qualitative study, we uncover five patterns which can be followed to generate artificial examples for complementing existing API usage examples in the API misuse detection. To evaluate the usefulness of the generated artificial examples, we apply a state-of-the-art example-based API misuse detector on 50 open source Java projects. We find that our artificial examples can complement the existing API usage examples by preventing the detection of 55 false API misuses. Furthermore, we conduct a pre-designed experiment in an automated API misuse detection benchmark (MUBench), in order to evaluate the impact of generated artificial examples on recall. We find that the API misuse detector covers the same true positive results with and without the artificial example, i.e., obtains the same recall of 94.7%. Our findings highlight the potential of improving API misuse detection by pattern-guided source code transformation techniques.

Assessing applicants for faculty positions in universities involves many issues. Each issue may involve a judgment based on uncertain or imprecise data. The uncertainty in data may exist in the interpretation made by the evaluator. This issue might lead to improper decision making. Modeling such a system using fuzzy logic will provide a more efficient model for handling imprecision. This article presents a fuzzy system for modeling the assessment of applicants for employment at academic universities. This system will utilize a multi-stage fuzzy model for measuring and evaluating the applicants. Utilizing fuzzy logic for applicants' evaluation will help administrators in choosing the best candidates for faculty positions. The fuzzy system was developed using jFuzzyLogic Java library. The reliability of the proposed system was proved by evaluating real-world case studies to prove its effectiveness to mimic human judgment. Moreover, the developed system has been evaluated by comparing it with a traditional mathematical method to prove the credibility and fairness of the proposed fuzzy system.

Technique in carrying out data compression is an important point in technological developments. With compression in data in the form of text can include many uses, including for data transfer, copying and for backing up data. From its uses, this aspect is important for data security. There are many compression techniques on the data, including using huffman algorithms and unary code. One of its applications will be implemented on a text data that is widely used by digital actors in storing important data. The data must not be known by unauthorized parties in accessing the data. Therefore, huffman algorithms and unary code can solve this problem. By compressing the selected data also encrypts it as an extra security. The Huffman algorithm is a lossless compression algorithm or a technique that does not change the original data, by converting the unit of data content into bits. So this algorithm is widely used in the compression process. The Unary Codes algorithm is also a lossless compression technique that is generally used by combining several modification techniques. In this unary codes algorithm, each symbol in the string will be searched for its frequency. Then sorted from the last order (descending). The use of these two text data compression techniques results in a file size that is smaller than the original but can be returned to the original data, Teknik dalam melakukan kompresi data merupakan suatu poin penting dalam perkembangan teknologi. Dengan kompresi dalam data berupa teks dapat mencakup banyak kegunaan, diantaranya untuk transfer data, melakukan penyalinan maupun untuk mencadangkan data. Dari kegunaan-kegunaannya tersebut aspek ini penting untuk keamanan data. Sangat banyak teknik kompresi pada data, diantaranya adalah dengan menggunakan algoritma huffman dan unary code. Salah satu penerapannya akan diimplementasikan pada suatu data teks yang banyak digunakan oleh pelaku digital dalam menyimpan data penting. Data tersebut tidak boleh diketahui oleh pihak yang tidak berwenang dalam mengakses data tersebut. Maka dari itu algoritma huffman dan unary code dapat memecahkan permasalahan tersebut. Dengan melakukan kompresi pada data yang dipilih juga mengenkripsinya sebagai pengamanan ekstra. Algoritma Huffman merupakan algoritma kompresi lossless atau teknik yang tidak mengubah data aslinya, dengan cara mengubah satuan isi data menjadi bentuk bit. Sehingga algoritma ini banyak dipakai dalam proses kompresi. Algotitma Unary Codes juga merupakan teknik kompresi lossless yang umumnya digunakan dengan menggabungkan beberapa teknik modifikasi. Dalam algoritma unary codes ini setiap simbol pada string akan akan dicari frekuensinya. Kemudian diurutkan dari urutan paling akhir (descending). Penggunaan dua teknik kompresi data teks ini menghasilkan ukuran file yang lebih kecil dari aslinya namun dapat dikembalikan lagi menjadi data asli tersebut.

An energy efficient information and communication system is a need of the day. Information technology related industries are making efforts to reduce power consumption by improvising both the hardware infrastructure and software systems. The hardware is driven by software; hence, design and development of software may have a significant impact energy need of the overall system. Many times it is observed that complex software performs useless tasks leading to power consumption, referred to as energy leak. The solution of energy leaks for mobile applications has attracted the interest of researchers, but still handling energy leaks issues for applications developed using Java-based technology need to be explored. While designing software during maintenance phase, code smells are introduced which not only reduce performance of the software also may lead to execution of useless code thus enhancing the energy leak. The common practice of the software industry to remove the code smells is use of refactoring strategy. The basic idea of this study is to understand the impact of refactoring on total energy consumption. To explore this hypothesis a set of Java based applications are selected, code smell present in these applications are discovered and a suitable refactoring strategy is applied to reduce the code smell. Power consumption is estimated using an open source tool Microsoft Joulemeter, it monitors energy usage by machine resources and estimates power consumption. The energy consumption before and after refactoring is recorded and statistical t-test is performed to validate the proposed concept.

API misuses are well-known causes of software crashes and security vulnerabilities. However, their detection and repair is challenging given that the correct usages of (third-party) APIs might be obscure to the developers of client programs. This paper presents the first empirical study to assess the ability of existing automated bug repair tools to repair API misuses, which is a class of bugs previously unexplored. Our study examines and compares 14 Java test-suite-based repair tools (11 proposed before 2018, and three afterwards) on a manually curated benchmark (APIREPBENCH) consisting of 101 API misuses. We develop an extensible execution framework (APIARTY) to automatically execute multiple repair tools. Our results show that the repair tools are able to generate patches for 28% of the API misuses considered. While the 11 less recent tools are generally fast (the median execution time of the repair attempts is 3.87 minutes and the mean execution time is 30.79 minutes), the three most recent are less efficient (i.e., 98% slower) than their predecessors. The tools generate patches for API misuses that mostly belong to the categories of missing null check, missing value, missing exception, and missing call. Most of the patches generated by all tools are plausible (65%), but only few of these patches are semantically correct to human patches (25%). Our findings suggest that the design of future repair tools should support the localisation of complex bugs, including different categories of API misuses, handling of timeout issues, and ability to configure large software projects. Both APIREPBENCH and APIARTY have been made publicly available for other researchers to evaluate the capabilities of repair tools on detecting and fixing API misuses.

International audience; Virtual threads are a highly anticipated feature in the Java world, aiming at improving resource efficiency in the JVM for I/O intensive operations while simplifying developer experience. This feature keeps the traditional thread abstraction and makes it compatible with most of the existing Java applications, allowing developers preferring synchronous imperative abstractions to benefit from better performance without switching to asynchronous and reactive programming models. However, limitations currently hinder the usability of virtual threads. These limitations must be considered when building a piece of software around virtual threads for they might have non-trivial effects. This paper (i) discusses the different strategies envisioned to leverage virtual threads in the Quarkus framework, (ii) gives an overview of the final implementation, (iii) presents the benchmark used to characterize the benefits of using virtual threads in a typical container environment where resources are scarce compared to using Quarkus with traditional thread pools and Quarkus with reactive libraries ; (iv) results are interpreted and discussed. Our study reveals that the integration of virtual threads in Quarkus doesn't perform as well as Quarkus-reactive. This seems to be due to a mismatch between the core hypothesis of Netty and virtual threads regarding the amount of threads available.

Programski jezik Java je eden najbolj uporabljenih jezikov na svetu, tako v profesionalnem, kot tudi v akademskem okolju. Priljubljen je predvsem zaradi preprostosti uporabe, sintakse, prevzete po programskem jeziku C, in moˇznosti izvajanja na veˇc platformah. V akademskem okolju pa pogreˇsamo moˇznost vstavljanja zloˇzne kode v prevedeno javansko kodo, kot nam to omogoˇcajo stavki asm v programskem jeziku C. V ta namen bomo izdelali program Jasm. Uporabnik bo preko uporabniˇskega vmesnika vnesel javansko kodo, v kateri bodo zapisani ukazi zloˇzne kode. Jasm bo program prevedel, vstavil zloˇzno kodo na pravilno mesto, program izvedel, rezultate pa vrnil na uporabniˇski vmesnik. The Java programming language is one of the most used programming lan- guages worldwide. It is popular in professional environments, as well as in the academic space. Java’s popularity is mostly based on its ease of use, C-like syntax and being cross-platform. However, in the academic space, the option to insert Java bytecode into compiled Java code, in the same way the asm statements work in C, would be useful. For that purpose we are going to implement a program called Jasm. Users will be able to write a Java program with bytecode, which is then going to be compiled, and executed with the bytecode inserted. Execution results will be returned to the user.

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, and SP, in which we have run a series of files containing flows of different rates. In conclusion, this research will exhibit that, on average, the RL algorithm consistently beats the other two algorithms by 16%, when it comes to reducing the data loss, which will improve the efficiency of the network.

During website development, the selection of suitable computer language and reasonable use of relevant open-source projects is imperative. Although the two languages, PHP and Java, have been extensively investigated in this context, there are not many security test reports based on their open-source projects. In this article, we conducted separate security analyses on web-related open-source projects based on PHP and Java. To this end, different open-source frameworks and services are used to design websites used to test experimental attacks on 12 popular open-source filters available on GitHub, as well as investigate the use of Lightweight Directory Access Protocol (LDAP) in the Firefox browser environment. Using malicious payloads published by Open Web Application Security Project (OWASP) and others, Cross-site Scripting (XSS), Local File Inclusion (LFI), SQL injection, and LDAP injection are performed on the test targets. The experimental results reveal that although PHP-based open-source projects are more vulnerable to attacks than Java-based ones, there is significant room for improvement. Finally, a whitelist-based filtering scheme is proposed. This scheme filters the inline attributes of label elements so that the filter has an excellent detection rate of malicious payloads while having an excellent pass rate of benign payloads. Effective references and suggestions for web developers are also included to aid the selection of open-source web projects, and feasible solutions to improve filter performance are proposed.

Perkembangan arus informasi merupakan perubahan yang harus dapat diadaptasi, salah satunya adalah penggunaan website dalam bidang usaha. Dalam kasus ini website digunakan sebagai platform informasi dan juga untuk memberi kepercayaan masyarakat dalam brand ini yaitu Eey.Id yang sedang dalam proses pertumbuhan guna mencari wadah dalam masyarakat agar nilai dari brand ini dapat tersampaikan dengan baik kepada khalayak luas. Permasalahan yang ingin ditanggulangi dari penelitian ini sendiri adalah peningkatan kinerja baik dari segi pemasaran, promosi dan kesadaran masyarakat tentang merk ini sendiri, sehingga dapat menghadirkan keloyalitasan dan kepuasan pelanggan. Website ini menggunakan framework Spring Boot dengan bahasa pemrograman Java dan database MySql, pilihan dalam menggunakan teknologi ini disebabkan penggunaan yang cukup baik dalam pembuatan dan juga untuk proses perawatan. Untuk tahap selanjutnya website ini akan dikembangkan sebagai sistem informasi mengenai brand Eey.Id sendiri, dimana terdapat pihak pihak yang akan memiliki hak akses dan penggunaannya masing-masing. Untuk pengumpulan data dan kebutuhan sendiri dilakukan menggunakan teknik kualitatif yaitu wawancara langsung terhadap pemilik Eey.Id sendiri, dari hasil wawancara tersebut dapat disimpulkan teknologi yang dianggap sesuai dengan kebutuhan yaitu menggunakan Spring Framework dan design pattern dari web server yang dibuat dengan bentuk MVC. Dari kerangka yang sudah dirancang menghasilkan output berupa sebuah website berbasis web server, dimana pemilik memiliki kemampuan untuk mengendalikan isi dari website ini. Isi dari website ini sendiri meliputi produk dan kemampuan pelanggan untuk menyampaikan keluhan dan saran. Manfaat dari web server ini sendiri adalah kemudahan untuk melakukan pemasaran yang repetitive dan meningkatkan feedback dari pelanggan, baik dari segi produk maupun pelayanan. Sehingga dapat membangun sisi kepercayaan dan keloyalitasan dari pelanggan, dampak ini dapat dirasakan ketika pelanggan dapat melihat secara langsung produk-produk yang ada dengan detail lebih mendalam dibandingkan sekedar menjual di platform-platform tertentu. The development of information flow is a change that must be adapted, one of which is the use of websites in the business field. In this case, the website is used as an information platform and also to give people trust in this brand, which is Eey.Id that is in the process of growth to find a place in the community so that the value of this brand can be conveyed well to a wide audience. The problem to be overcome from this research itself is the improvement of performance both in terms of marketing, promotion and public awareness about this brand itself, so that it can bring loyalty and customer satisfaction. This website uses the Spring Boot framework with Java programming language and MySql database, the choice in using this technology is due to its good use in manufacturing and also for the maintenance process. For the next stage, this website will be developed as an information system about Eey.Id own brand, where there are parties who will have their own access and use rights. For data collection and own needs carried out using qualitative techniques, namely direct interviews with Eey.Id owners themselves, from the results of the interview can be concluded technology that is considered in accordance with needs, namely using Spring Framework and design patterns from web servers made in the form of MVC. From the framework that has been designed produces output in the form of a web server-based website, where the owner has the ability to control the content of this website. The content of this website itself includes products and the ability of customers to submit complaints and suggestions. The benefit of this web server itself is the ease of doing repetitive marketing and increasing feedback from customers, both in terms of products and services. So that it can build trust and loyalty from customers, this impact can be felt when customers can see directly the existing products in more depth than just selling on certain platforms.

[Resumen]: El sector eCommerce ha supuesto una revolución mundial en lo que a transacciones comerciales respecta y, en consecuencia al aumento disparado de su crecimiento en 2020 durante la pandemia, las ventas de este sector han crecido alrededor de un 50% desde entonces. En España, alrededor de 3.5 millones de españoles de entre 16 y 24 años adquirieron en 2022 algún tipo de producto o servicio en internet, una cifra que supera los 8 millones si se tienen en cuenta a los individuos de entre 25 a 34 años [1]. Tanto si hablamos específicamente de aplicaciones de compra-venta de primera o segunda mano (Wallapop, Vinted, etc.), como marketplaces (Amazon, Mediamarkt, etc.) o webs de negocios locales dedicados a la venta online, los vendedores o tiendas comparten en numerosas ocasiones la problemática de no saber con detalle qué rendimiento están teniendo sus anuncios sobre uno o varios artículos puestos a la venta y, en general, la ausencia de herramientas que le permitan estudiar con claridad estrategias creativas de venta que le permitan, en muchas ocasiones, dar salida al género. A partir de este problema, surge la necesidad del desarrollo de una solución software a través de una aplicación multiplataforma web y móvil, que permita gestionar y monitorizar los artículos de un eCommerce de una forma clara y eficiente. En este proyecto se aborda la creación de esta solución. [Abstract]: The eCommerce sector has brought about a global revolution in terms of commercial transactions and, as a result of the skyrocketing growth in 2020 during the pandemic, sales in this sector have grown by around 50% since then. In Spain, around 3.5 million Spaniards between the ages of 16 and 24 purchased some type of product or service on the Internet in 2022, a figure that exceeds 8 million if individuals between the ages of 25 and 34 are taken into account [1]. Whether we are talking specifically about first or second-hand buying-selling applications (Wallapop, Vinted, etc.), such as Marketplaces (Amazon, Mediamarkt, etc.) or local business websites dedicated to online sales, sellers or stores share on numerous occasions, the problem of not knowing in detail how your ads are performing on one or several items for sale and, in general, the absence of tools that allow you to clearly study creative sales strategies that allow you, in many occasions, give outlet to the genre. From this problem, the need arises for the development of a software solution through a multiplatform web and mobile application, which allows the management and monitoring of eCommerce items in a clear and efficient way. In this project, we will cover creating this solution. Traballo fin de grao (UDC.FIC). Enxeñaría Informática. Curso 2022/2023

[Resumo]: Para levar a cabo o aluguer dunha vivenda (tarefa realizada por gran parte da poboación) é preciso, entre outras, a procura da vivenda, a xestión dos gastos, a interacción cun arrendador e a procura de compañeiros. O obxectivo deste traballo é o deseño e desenvolvemento dunha aplicación web con tecnoloxías Java/Spring Boot e JavaScript/React para simplificar as tarefas de xestión relacionadas co aluguer de vivendas. A aplicación contemplará dous tipos de perfís de usuarios diferentes: arrendadores e clientes. Calquera usuario poderá realizar procuras, visualizalos detalles dunha vivenda e ver as valoracións dos arrendadores. Os usuarios con perfil de arrendador poderán poñer en aluguer os seus inmobles, así como modificalos ou dalos de baixa. Os clientes poderán acceder aos inmobles publicados na web para alugalos. A aplicación proporcionará tamén un sistema de mensaxería de texto entre os diferentes usuarios, así como para interaccionar cos anuncios de procura de compañeiros e incidencias sobre os inmobles. Incluirá unha funcionalidade para publicar os gastos e realizar os pagos, e os inquilinos poderán valorar aos arrendadores para que outros posibles arrendatarios poidan ver as súas valoracións e comentarios antes de alugar. [Abstract]: Renting a house (a task carried out by a large part of the population) requires, among other things, house searching, bills management, the interaction with a host and the search for roommates. The objective of this work is the design and development of a web application with Java/Spring Boot and JavaScript/React technologies to simplify the management tasks related to the houses rents. The application will consider two different types of user profiles: hosts and customers. Any user will be able to search, view the details of a house and see the ratings of hosts. Users with a host profile will be able to rent their properties, as well as modify or cancel them. Customers will be able to access the properties published on the web to rent them. The application will also provide a text messaging system between the different users, as well as to interact with the announcements of the search for roommates and incidences on the house. It will include functionality to post bills and make payments, and customers will be able to rate hosts so other potential customers can see their ratings and comments before rent.

[Resumen]: La lucha contra incendios forestales en Galicia es un desafío constante debido a la alta incidencia de incendios y su impacto devastador en el ecosistema y las comunidades locales. Aunque existen tecnologías de detección temprana, como satélites y líneas telefónicas gratuitas, la falta de interconexión y compartición de datos limita su eficacia. El objetivo de este trabajo de fin de grado es el diseño e implementación de una aplicación web con tecnologías Java/SpringBoot y JavaScript/React que permita centralizar la gestión de alertas de incendios, así como los propios incendios, personal y equipos involucrados en su extinción. La aplicación contará con una representación gráfica sobre un mapa de las áreas afectadas por los incendios, y además almacenará información sobre los incendios extinguidos y su evolución. Incluirá también información meteorológica en tiempo real para ayudar en la toma de decisiones que permitan determinar la mejor línea de actuación en cada caso. [Abstract]: The fight against forest fires in Galicia is a constant challenge due to the high incidence of fires and their devastating impact on the ecosystem and local communities. Although early detection technologies such as satellites and toll-free phone lines exist, the lack of interconnection and data sharing limits their effectiveness. The objective of this undergraduate thesis is the design and implementation of a web application using Java/SpringBoot and JavaScript/React technologies that centralizes the management of fire alerts, as well as the fires themselves, personnel, and equipment involved in their extinguishment. The application will feature a graphical representation on a map of the areas affected by the fires and will also store information about extinguished fires and their progression. It will also include real-time weather information to assist in decision-making that determines the best course of action in each case. Traballo fin de grao (UDC.FIC). Enxeñaría Informática.

Teaching Java programming language in educational systems poses several challenges for both educators and students. Java is a complex programming language with a steep learning curve that requires extensive practice and hands-on experience to master. Furthermore, teaching advanced concepts and techniques, such as multithreading and memory management, can be difficult, and the limited availability of qualified and experienced Java instructors can hinder the quality of education. The lack of interactivity, visual aids, and multimedia features can also limit student engagement and motivation, {"references":["Azizjon Mo'minjon o'g X. et al.

In today's world, the personal information of any person can be conventionally divided into two large categories: general and special. As you can understand from the name, the first category is responsible for the type of data that can be found in public access, namely: surname, first name, patronymic, signature, place and date of birth, citizenship, marital status, education, bank details, etc. Such a variety of personal data requires different methods and automated means of storage. Today, private and state institutions increasingly refuse to store information in paper form. This is explained by the low level of security of such storage facilities, which can be affected by fire, water, pests, etc. Information that exists in paper form is very easy to lose, for example, misplaced or lost during movement. It is shown that digital storage of information makes it possible to get rid of such problems. Personal data that is stored electronically can often be recovered even if the device from which it was accessed is lost. One of the main types of personal information in modern society is login data: login and password. That is why the algorithmic and software of the automated system for saving the user's personal data was developed. This system should enable the user to generate passwords resistant to standard hacking methods and store them in the database. The development of the automated system took place using the MVC architectural template, which is one of the options for implementing a multi-level architectural model. For detailed design and coding, an object-oriented Java programming language with static strict typing was chosen. It was also decided to develop an automated system in the form of a web application using the Spring framework. During the development process, a local database was designed, which will store personal data in the form of logins and passwords entered by the user or generated by the system itself. An algorithm for generating hack-resistant passwords has been developed. Hash algorithms are also used as an additional protection of the main password of the web application. A graphical interface has been created that allows the user to access the main functions of the automated system., У сучасному світі персональну інформацію будь-якої людини можна умовно розділити на дві великі категорії: загальна та особлива. Як можна зрозуміти з назви, перша категорія відповідає за той тип даних, які можна знайти у загальному доступі, а саме: прізвище, ім’я, по-батькові, підпис, місце та дата народження, громадянство, сімейний стан, освіта, банківські реквізити, тощо. Подібне різноманіття персональних даних потребує різних методів та автоматизованих засобів зберігання. Сьогодні все частіше приватні та державні установи відмовляються від зберігання інформації у паперовому вигляді. Це пояснюється низьким рівнем безпеки таких сховищ, які можуть постраждати від вогню, води, шкідників, тощо. Показано, що цифрове зберігання інформації дозволяє позбутися подібних проблем. Персональні дані, які зберігаються в електронному вигляді, найчастіше можна відновити навіть при втраті пристрою, з якого здійснювався доступ до них. Одним із основних видів персональної інформації в сучасному суспільстві є дані для входу: логін та пароль. Саме тому було розроблено алгоритмічне та програмне забезпечення автоматизованої системи збереження персональних даних користувача. Дана система має надати можливість користувачу генерувати стійкі до стандартних методів зламу паролі та зберігати їх у базі даних. Розроблення автоматизованої системи проходило з використанням архітектурного шаблону MVC, який є одним з варіантів реалізації багаторівневої архітектурної моделі. Для детального проектування та кодування обрано об’єктно-орієнтовну мову програмування зі статичною строгою типізацією Java. Також прийнято рішення розробити автоматизовану систему у вигляді веб-додатку за допомогою використання фреймворка Spring. У ході процесу розроблення спроектовано локальну базу даних, в якій зберігатимуться персональні дані у вигляді логінів та паролів, які ввів користувач або згенерувала сама система. Розроблено алгоритм генерації стійких до зламу стандартними методами паролів. Також використано алгоритми хешування, як додатковий захист головного пароля від веб-додатку. Створено графічний інтерфейс, який дозволяє користувачу отримати доступ до основних функцій автоматизованої системи.

Traditional distribution of programming problems seems to create dissatisfaction among students. To overcome this problem, complexity measurement of programming problems is necessary. Although software is the outcome of human ingenious activity, cognitive informatics plays a significant role in understanding its ultimate characteristics. In this article, we have proposed a software complexity measurement algorithm based on cognitive weight of basic control structure that shrink the limitations of existing measures. Cognitive weight concept of any basic control structure are morally based on the rational capacity of Human Brain. According to cognitive data, we have developed a new software tool using Java Standard Edition and MySQL to measure the cognitive complexity by following our developed algorithm. This software is structured and developed based on the outcome of our research data which is capable of determining the complexity value of several programming languages. This will assist the instructors allocating the problems among the learners by preserving the equivalent level of difficulty. Therefore, the developed complexity measurement tool will ensure the students to get problems with identical difficulty level for assessment.

In this paper we introduce FAME-Core, a Java library supporting development and execution of agent-based simulation models (ABM). It is a main component of the open Framework for distributed Agent-based Models of Energy systems. FAME-Core offers rapid development and fast simulation execution capabilities while reducing required programming skills and efforts for creating and running complex ABM.

V diplomski nalogi smo predstavili mobilno aplikacijo razvito za Android operacijski sistem. Ta prototip aplikacije je namenjen izpolnjevanju delovnih nalogov za delavce na terenu v določenem podjetju. Z aplikacijo se bodo izognili papirnemu sistemu izpolnjevanja delovnih nalogov ter njihovega ročnega vnosa v podatkovno bazo podjetja. S tem bo čas vnosa podatkov krajši, saj bo potekal avtomatsko iz mobilne naprave prek strežnika v njihovo podatkovno bazo. Aplikacijo smo razvijali s pomočjo platforme Android studio, programirali smo s programskim jezikom Java. In my graduation thesis we presented a mobile application developed for the Android operating system. This prototype application is intended to create work orders for field workers in a specific company. With the application, they will avoid the paper system of writing work orders and entering them in the company’s database. This will shorten the data entry time, as it will run automatically from the server to the database. The application was developed using the Android studio platform, programmed using the Java programming language.

This note builds on an earlier Warta note (Doust, 2022) that summarised the geological development of the island of Trinidad and the margins of the Caribbean Sea. Parts of Southeast Asia can be readily compared to these areas and, I believe, the two provinces can provide valuable analogues for each other. I illustrate this by considering examples of tectonic style taken from transpressional fold belts in Trinidad and eastern Java, from the evolution of foreland and wrench basin stratigraphy and from striking similarities between the stratigraphy and structure of Borneo and Trinidad’s Tertiary continent margin deltas.

The current study is intended to explore the typology of other-initiated self-repair in term of its frequency of occurrence and to investigate the mechanism of self-repair in an academic setting. To obtain the required data, a classroom conversational analysis was conducted in which the researchers observed a group of graduate students (19 active EFL speakers) in a state university in East Java, Indonesia. Based on the qualitative data analysis, the results of the study revealed that all typologies of other-initiated selfrepair were used depending on the aims the interlocutors try to gain since all typologies have diverse aims and ways. Of all typologies, confirming checks were dominantly used by the participants. Regarding the mechanisms, three types of mechanisms were found; full two-cycle repair, background check, and short-cut repair sequence.

This study aims to examine EFL learners’ perception toward the application of Orai App in CLL method in teaching speaking. The study employed likert-scale questionnaires to enable researchers to collect massive data. The total of 24 first year students of a private university in East Java – Indonesia, comprising of 5 male and 19 female students participated in this study. Data were analyzed using descriptive statistic by finding out the total score per item. The results of this study illustrated that Orai application helps students alleviate the fear of speaking. It can also help students in increasing their speaking ability on the aspects of pronunciation, intonation as well as the speaking speed. Based on the data analysis, CLL method assisted by Orai application is strongly recommended to be used to assist the students to be better speaker.

Vulnerable dependencies are a known problem in today's free open-source software ecosystems because FOSS libraries are highly interconnected, and developers do not always update their dependencies. Our paper proposes Vuln4Real, the methodology for counting actually vulnerable dependencies, that addresses the over-inflation problem of academic and industrial approaches for reporting vulnerable dependencies in FOSS software, and therefore, caters to the needs of industrial practice for correct allocation of development and audit resources. To understand the industrial impact of a more precise methodology, we considered the 500 most popular FOSS Java libraries used by SAP in its own software. Our analysis included 25767 distinct library instances in Maven. We found that the proposed methodology has visible impacts on both ecosystem view and the individual library developer view of the situation of software dependencies: Vuln4Real significantly reduces the number of false alerts for deployed code (dependencies wrongly flagged as vulnerable), provides meaningful insights on the exposure to third-parties (and hence vulnerabilities) of a library, and automatically predicts when dependency maintenance starts lagging, so it may not receive updates for arising issues.

Running applications on a rooting device makes the application vulnerable to data leakage. Therefore, many applications that require a high level of security are not allowed to run on rooted device. Common technique of detecting rooted device is by using Android API to discover rooting trace. However, the detection can be bypassed using Java function hooking script by the people who want to run the app on rooted device. This research will give illustration that the bypassing process becomes more easy with automation tool and hybrid analysis. In order to create the script, we use combination of static and dynamic analysis with three phases with specific function. Phase 1 aims to detect the estimated Java method that detect rooting, phase 2 will analyze that method on an unrooted device, then phase 3 will create the bypassing script based on the previous result. We also use automation tool to speed up the static analysis. We create two types of script: one that can be used on general application, and the other one that only can be used on specific app. Those types implement different scope: one with the certain Java method, and the other one with specific parameter or return value. In the end, we find that bypassing rooting detection is not complicated if the app use Java function to detect the rooted device. To complicate bypassing process, we encourage the developers to implement more advanced detection rooting technique.

International audience; The advent of mobile computing has changed the shape of distributed computing. Mobile devices now have enough computational capabilities to take part of distributed computations. Thanks to their wireless networking interfaces, they can have direct interactions with their peers, self-organize in dynamic multi-hop networks, like the Internet of Things (IoT), the Edge, Mobile Ad hoc Networks (MANETs), etc. Such networks exhibit a number of inherent characteristics (mobility, unpredictability, scarce connections, etc) which make it difficult the use of their resources by (distributed) applications. Because existing middleware for distributed computing was most often designed to operate on clouds/grids/clusters, it can hardly be used in these networks. IDAWI belongs to a new class of middleware solutions which rely on decentralization to federate the resources of dynamic multi-hop networks, to the purpose of facilitating the design and implementation of distributed applications in networks of mobile devices. IDAWI goes further by proposing a collective stream-oriented computing model that matches the very nature of such networks. This permitted us to design, implement and describe in this article the architecture of a specific decentralized Web backend exposing as a whole the resources of a dynamic multi-hop network as a set of Web services. In order to profit from the stream-oriented and collective natures of IDAWI 's computation model, these Web services make a clever use of several standard Web technologies they rely on. All the concepts presented in this paper can be found in an Open Source reference implementation.

Mobilna aplikacija Domus i istoimena web aplikacija dvije su aplikacije za fiktivni salon namještaja koje ostvaruju povezanost s MySQL bazom podataka preko koje vrše komunikaciju i razmjenu potrebnih podataka. Mobilna aplikacija razvijena je u programu Android Studio, korištenjem programskog jezika Java i označnog jezika XML, dok je web aplikacija razvijena na HostGator serveru korištenjem programskog jezika PHP i označnog jezika HTML, uz dodatno korištenje stilskog jezika CSS i programskog jezika JavaScript. Baza podataka razvijena je na HostGator serveru korištenjem alata phpMyAdmin. Mobilna aplikacija stvorena je za korištenje samo krajnjim korisnicima koji u njoj mogu pregledavati ponudu koja je pohranjena u bazi podataka te se prikazuje mobilnoj aplikaciji korištenjem programskog jezika PHP, čije skripte potrebne podatke iz baze šalju u JSON formatu prema mobilnoj aplikaciji koja koristi HTTP biblioteku Volley za iščitavanje tih podataka i prikaz istih u korisničkom sučelju mobilne aplikacije. Korisnik ima mogućnosti stvarati narudžbe koje se također preko Volley-a u JSON formatu šalju prema serveru gdje ih onda PHP dekodira i dobivene podatke pohranjuje u bazu podataka. Web aplikacija stvorena je da bude pogodna za rad administratoru, ali i krajnjim korisnicima. Podijeljena je u dva dijela, s tim da administratorskom dijelu aplikacije mogu pristupiti samo korisnici koji imaju administratorske privilegije. Kao i u slučaju mobilne aplikacije, standardni korisnik može pregledavati ponudu, ali za razliku od mobilne aplikacije, narudžbe može stvarati samo uz prijavu. Korisnik u web aplikaciji također ima mogućnost pregledavati i svoje prethodno stvorene narudžbe. Administrator koristi administratorsku ploču za pregled svih narudžbi, te također može vršiti CRUD operacije nad ponudom. The Domus mobile application and the homonymous web application are two applications for a fictitious furniture salon that connect to a MySQL database through which they communicate and exchange data. The mobile application was developed in the Android Studio program, using the Java programming language and the XML markup language, while the web application was developed on the HostGator server using the PHP programming language and the HTML markup language, with the additional use of the CSS style sheet language and the JavaScript programming language. The database was developed on the HostGator server using the phpMyAdmin administration tool. The mobile application was created to be used only by end users who can view the offer stored in the database and displayed to the mobile application using the PHP programming language, whose scripts send the necessary data from the database in JSON format to the mobile application using the Volley HTTP library for reading this data and displaying it in the mobile application's user interface. The user has the ability to create orders that are also sent via Volley in JSON format to the server, where PHP then decodes them and stores the resulting data in the database. The web application was created to be convenient for the administrator, but also for end users. It is divided into two parts, with the fact that the administrative part of the application can only be accessed by users who have administrator privileges. As in the case of the mobile application, the standard user can view the offer, but unlike the mobile application, they can only create orders by logging in. In the web application, the user also has the possibility to view his previously created orders. The administrator uses the admin panel to view all orders, and can also perform CRUD operations on the offer.

Struktura ovo rada dijeli se na teorijski i praktični dio razvoja mobilne aplikacije za dopisivanje s prijevodom. U prvom dijelu rada opisane su tehnologije i alati koji su korišteni pri izradi same aplikacije. Zatim imamo nekoliko dijagrama koji objašnjavaju način rada aplikacije. Teorijski dio zaključen je swot analizom koja nam je omogućila da ispravno sagledamo unutrašnje snage i slabosti aplikacije te vanjske prilike i prijetnje s kojima se aplikacija susreće. U nastavku prikazana je implementacija mobilne aplikacije, koja ujedno predstavlja i praktični dio rada. Na kraju su korisničke upute koje su napisane u svrhu lakšeg snalaženja korisnika pri korištenju same aplikacije. The structure of this paper is divided into a theoretical and a practical part of the development of a mobile application for correspondence with translation. The first part of the paper describes the technologies and tools that were used in the creation of the application itself. Then we have a few diagrams that explain how the app works. The theoretical part was concluded with a swot analysis that allowed us to correctly see the internal strengths and weaknesses of the application and the external opportunities and threats that the application faces. Below is the implementation of the mobile application, which also represents the practical part of the work. At the end, there are user instructions that were written for the purpose of making it easier for users to find their way around when using the application itself

Generics are a powerful tool in object-oriented programming languages, especially in the Java programming language. They play an important role in software development, since they enable the programmer to write typeindependent code in a type-safe way. In a nutshell, a generic Java class (or method) is a class (or method) parameterized with an arbitrary number of types. When using a generic class or method, we specify concrete values for the type parameters, effectively tailoring the code of the class or method for concrete types. Another benefit of Java generics is that type safety is enforced during compilation rather than execution. The C++ programming language has a concept parallel to Java generics these are templates. C++ templates and Java generics are similar to one another in terms of code syntax, the provided support for parameterizing types, and the most frequent use cases. However, they are actually implemented in a significantly different way, and there are important differences in their use and background semantics. In this thesis, we will show examples for both Java generics and C++ templates. We will discuss their similarities and differences, as well as advantages and disadvantages. Generiki so močno orodje v objektno usmerjenih programskih jezikih, še zlasti v jeziku java. Pri razvoju programske opreme igrajo pomembno vlogo, saj omogočajo programerju, da piše kodo, ki je neodvisna od konkretnih tipov, a kljub temu jamči pravilno rabo tipov. Generični javanski razred (oz. metoda) je v osnovi razred (oz. metoda), ki je parametriziran(a) s poljubnim številom tipov. Pri uporabi generičnega razreda oz. metode podamo konkretne vrednosti za tipne parametre in tako prilagodimo kodo razreda oz. metode za konkretne tipe. Druga prednost javanskih generikov je, da se skladnost tipov preverja že v času prevajanja, ne šele v času izvajanja. Koncept, podoben generikom v javi, obstaja tudi v jeziku C++: to so t.i. predloge. Predloge v C++ in generiki v javi so si med seboj podobni po sintaksi, po podpori parametrizaciji tipov in po najpogostejših primerih uporabe, močno pa se razlikujejo po implementaciji. Bistvene razlike lahko najdemo tudi pri uporabi in semantiki generikov in predlog. V tej diplomski nalogi se bomo ukvarjali tako z generiki v javi kot s predlogami v C++. Govorili bomo o njihovih medsebojnih podobnostih in razlikah, pa tudi o prednostih in slabostih.

[Resumen]: Gracias a los recientes avances en el campo de la medicina, los especialistas clínicos pueden realizar diagnósticos más precisos y personalizados de una serie de relevantes enfermedades. En particular, en el campo de la oftalmología, existen varios procedimientos de diagnóstico que utilizan diferentes tipos de tecnologías de captura de imagen del fondo de ojo. Algunas de las más utilizadas para evaluar el grado de deterioro de las células fotorreceptoras de la retina son la tomografía de coherencia óptica (OCT) y la microperimetría. En particular, la OCT es una técnica de imagen tomográfica que posibilita el estudio de las estructuras internas de un tejido como en este caso el de la retina. Por otro lado, la microperimetría, una técnica de diagnóstico que mide la sensibilidad de la mácula, también puede mostrar cualquier lesión incipiente en la zona central de la retina. El proceso de diagnóstico se realiza mediante la inspección visual de una gran cantidad de imágenes del paciente. A esto se suma que para realizar un análisis multimodal, es necesario comparar informaciones de distintos dispositivos, lo que resulta costoso y requiere mucho tiempo. La plataforma web para la gestión clínica y mejora del análisis multimodal que se ha desarrollado incluye varios módulos para facilitar el análisis automático de la región de los fotorreceptores en imágenes de la retina. Esta herramienta asiste al experto clínico al proporcionar información multimodal de las imágenes de ambas modalidades (OCT y microperimetría) para establecer un diagnóstico preciso de diferentes patologías oculares y sistémicas. Los módulos de la plataforma incluyen: (I) Módulo de segmentación de las capas retinianas en imágenes OCT, (II) Módulo de extracción de características de la capa de fotorreceptores, (III) Módulo de creación de mapas de las características extraídas, (IV) Módulo de comparación de características con la información del microperímetro, y (V) Módulo de visualización de la información obtenida. Además, la plataforma cuenta con un módulo de gestión de usuarios, pacientes, pruebas, informes e imágenes para facilitar el trabajo de los oftalmólogos, y un módulo de visualización intuitiva de la información. Esta plataforma está diseñada de manera tal que es posible integrar nuevos módulos para el diagnóstico de forma sencilla y flexible. Esto permite a los médicos realizar diagnósticos más precisos y personalizados de diferentes enfermedades oculares y sistémicas, lo que puede tener un impacto positivo en la calidad de vida de los pacientes. [Abstract]: Thanks to recent advances in the field of medicine, clinical specialists are able to make more accurate and personalized diagnoses of a range of relevant diseases. In particular, in the field of ophthalmology, there are several diagnostic procedures that use different types of eye fundus imaging technologies. Some of the most widely used for evaluating the degree of deterioration of the retina’s photoreceptor cells are optical coherence tomography (OCT) and microperimetry. In particular, OCT is a tomographic imaging technique that enables the study of the internal structures of a tissue such as the retina. On the other hand, microperimetry, a diagnostic technique that measures the sensitivity of the macula, can also show any early damage in the central area of the retina. The diagnostic process is carried out through the visual inspection of a large number of patient images. To this is added that to perform a multimodal analysis, it is necessary to compare information from different devices, which is costly and takes a lot of time. The web platform for clinical management and improvement of multimodal analysis that has been developed includes several modules to facilitate the automatic analysis of the photoreceptor region in retina images. This tool assists the clinical expert by providing multimodal information from images of both modalities (OCT and microperimetry) to establish a precise diagnosis of different ocular and systemic pathologies. The modules of the platform include: (I) Module for segmenting retinal layers in OCT images, (II) Module for extracting features of the photoreceptor layer, (III) Module for creating maps of the extracted features, (IV) Module for comparing features with microperimeter information, and (V) Module for visualizing the obtained information. In addition, the platform has a user, patient, test, report, and image management module to facilitate the work of ophthalmologists, and an intuitive visualization module for the information. This platform is designed in such a way that it is possible to easily and flexibly integrate new modules for diagnosis. This allows doctors to make more accurate and personalized diagnoses of different ocular and systemic diseases, which can have a positive impact on the quality of life of patients.

[Resumen]: El proyecto tiene como objetivo el diseño e implementación de una plataforma software para una empresa de administración de Comunidades de Propietarios (CC.PP) que permita administrar las llaves que posean de las mismas. Para conseguirlo, se desarrollará una aplicación móvil que permita a los empleados gestionar los préstamos de llaves a clientes y proveedores y crear incidencias para las llaves en caso de ser necesario. El objetivo principal de esta aplicación es agilizar el proceso de entrega de llaves y facilitar al cliente o proveedor información actualizada sobre el estado de la llave y el lugar concreto donde se encuentra la puerta. Por otra parte, se desarrollará una aplicación web Single Page Application (SPA) destinada a la posterior administración de las incidencias, usuarios y generación de listados. La aplicación web está pensada para poder realizar gestiones telefónicas a la vez que se cubre la información de una incidencia o verificar el estado de una llave en caso de que un cliente o proveedor esté interesado en retirarla. Ambas aplicaciones soportarán funcionalidades como la creación de CC.PP, bloques, llaves o generación de diferentes informes en Portable Document Format (PDF). Además, compartirán el mismo backend, que se compone de una Application Programming Interface (API) Representational State Transfer (REST) desarrollada en Java apoyándose en Spring Boot (con Hibernate, Java Persistence API (JPA) y PostgreSQL). Para el frontend, se hará uso de Flutter y como lenguaje se usará Dart. [Abstract]: The project aims to design and implement a software platform for a Community of Property Owners management company that allows the management of the keys they possess. To achieve this, a mobile application will be developed that allows employees to manage key loans to customers and suppliers and create incidents for the keys if necessary. The main goal of this application is to streamline the key delivery process and provide the customer or supplier with updated information on the status of the key and the specific location of the door. On the other hand, a SPA web application will be developed for the subsequent management of incidents, users and generation of lists. The web application is designed to be able to make telephone management while covering the information of an incident or checking the status of a key in case a customer or supplier is interested in retrieving it. Both applications will support functionalities such as the creation of Community of Property Owners, blocks, keys or the generation of different reports in PDF. Additionally, they will share the same backend, consisting of a REST API developed in Java using Spring Boot (with Hibernate, JPA and PostgreSQL). The frontend will be implemented using Flutter, with Dart as language. Traballo fin de grao (UDC.FIC). Enxeñaría Informática. Curso 2022/2023
