A standard of describing the process of displaying interactive windows on a computer monitor, through which an output of questions and input of answers are implemented during computer testing, is presented in the article [11]. According to the proposed standard, the description of the process mentioned above is performed with a format line, containing element names, their parameters as well as grouping and auxiliary symbols. Program objects are described using elements of standard. The majority of objects create input and output windows on a computer monitor. The aim of our research was to develop a minimum possible set of elements of standard to perform mathematical and computer science testing.The choice of elements of the standard was conducted in parallel with the development and testing of the program that uses them. This approach made it possible to choose a sufficiently complete set of elements for testing in fields of study mentioned above. For the proposed elements, names were selected in such a way: firstly, they indicate their function and secondly, they coincide with the names of elements in other programming languages that are similar by function. Parameters, their names, their assignments and accepted values are proposed for the elements. The principle of name selection for the parameters was the same as for elements of the standard: the names should correspond to their assignments or coincide with names of similar parameters in other programming languages. The parameters define properties of objects. Particularly, while the elements of standard create windows, the parameters define object properties (location, size, appearance) and the sequence in which windows are created. All elements of standard, proposed in this article are composed in a table, the columns of which have names and functions of these elements. Inside the table, the elements of standard are grouped row by row into four sets: input elements, output elements, input-output elements, grouping elements. All parameters are collected into another table, columns of which have names, assignments and values of parameters. Elements, for which the parameters are intended, are indicated in whole lines inside of this table. After each table, the necessary explanations are given to some of its items.An eхаmple of use of the standard for creating an input window of polynomial coefficients is demonstrated at the end of this article. The example shows significant compactness and ease of recording. Moreover, the testing program, based on the elements of standard, proposed in this article was written on HTML, JavaScript, PHP program languages and allows to perform mathematical and computer science testing. The program is available on the website [20]. Students of Moscow State (National Research) University of Civil Engineering were tested frequently using this program.The composition of elements and their parameters proposed above is convenient and does not require the creators of test problems to have a high level knowledge of programming languages.

Abstract An end-to-end platform for chemical science research has been developed that integrates data from computational and experimental approaches through a modern web-based interface. The platform offers an interactive visualization and analytics environment that functions well on mobile, laptop and desktop devices. It offers pragmatic solutions to ensure that large and complex data sets are more accessible. Existing desktop applications/frameworks were extended to integrate with high-performance computing resources, and offer command-line tools to automate interaction—connecting distributed teams to this software platform on their own terms. The platform was developed openly, and all source code hosted on the GitHub platform with automated deployment possible using Ansible coupled with standard Ubuntu-based machine images deployed to cloud machines. The platform is designed to enable teams to reap the benefits of the connected web—going beyond what conventional search and analytics platforms offer in this area. It also has the goal of offering federated instances, that can be customized to the sites/research performed. Data gets stored using JSON, extending upon previous approaches using XML, building structures that support computational chemistry calculations. These structures were developed to make it easy to process data across different languages, and send data to a JavaScript-based web client.

In companies environments, it is normal to exist several systems to ease daily activities. In academic environments, it also happens. However, academic environments may be even more heterogeneous as there are many specialized activities, such as: restaurant, library, academic processes, administrative processes and computer network services, such as email and network authentication. To maintain the data consistency throughout the systems, all the systems must be integrated. This integration was carried out in the Federal University of Lavras by using Simples Object Access Protocol (SOAP) as communication protocol. The development of a new system (mobile application), it was noticed that SOAP is very CPU-intensive and slow, as mobile devices have constraints such as internet and processing. Thus, a REST-JSON layer to integrate mobile application and the integration architecture was developed, benefiting from all the resources the integration architecture had. By using this new layer, the offer of functions from the integration architecture was also expanded to REST, attending to other applications without having to make big changes in the code. It was measured that the REST-JSON layer consumes around 73% less data than SOAP. The REST-JSON layer was released, attending to about 5600 installations of the application that requests the integration around 54000 times a day.

Teknologi terus menerus berkembang, berbagai jenis teknologi terus bermunculan seperti sistem informasi manajemen arsip, masalahnya para pekerja kadang melakukan pekerjaan lain di komputer sehingga arsip tidak terkontrol. Penerapan Web Push Notification dapat menampilkan pemberitahuan berbasis website meskipun tidak membuka web browser secara langsung atau dalam kondisi minimize. Web Push Notification merupakan mekanisme pemberitahuan menggunakan Javascript pada web browser. Fitur ini tersedia dalam Push API HTML5 dengan menggunakan Push Service atau Messaging server yang mengirim pemberitahuan ke web browser yang telah berlangganan tanpa membuka website sehingga dapat melakukan broadcast message dan Notification API HTML5 tidak memerlukan Push Service atau Messaging server tetapi harus membuka website, tetapi belum didukung semua web browser sehingga pada makalah ini dibahas Implementasi Web Push Notification pada sistem informasi manajemen arsip menggunakan PushJS, metode pengembangan yang digunakan adalah Rational Unified Proccess (RUP). Teknologi pemberitahuan yang cocok untuk sistem informasi manajemen arsip berbasis web yaitu Notification API HTML5 karena tidak akan mengirim pemberitahuan yang sama ke semua pengguna. Namun tidak ada proses di belakang layar sehingga tidak akan dijalankan secara otomatis, masalah tersebut diatasi dengan menggunakan AJAX dengan mengambil JSON kemudian dijalankan berulang-ulang pada web browser dan meminimalisir bentrokan antara script web push notification di multi tab window atau window web browser diatasi menggunakan localStorage dari WebStorage API HTML5. Hasil uji menunjukan bahwa penerapan teknologi Web Push Notification pada Sistem Informasi Manajemen Arsip dapat membantu para pengguna dalam mengelola arsip yang banyak serta penggunaan AJAX berpengaruh terhadap kecepatan akses web. Abstract Technology continues to evolve, various types of technology continue to emerge such as records management information systems, the problem is that workers sometimes do other work on the computer so that the archive is not controlled. Web Push Notification application can display website-based notifications even if you don't open the web browser directly or in a minimized condition. Web Push Notification is a notification mechanism using Javascript in a web browser. This feature is available in the HTML5 Push API by using a Push Service or Messaging server that sends notifications to subscribed web browsers without opening the website so that it can broadcast and the HTML5 Notification API does not require a Push Service or Messaging server but must open a website, but not supported all web browsers so that this paper discusses Push Notification Web Implementation in archive management information systems using PushJS, the development method used is the Rational Unified Process (RUP). Notification technology that is suitable for web-based archive management information systems namely HTML5 Notification API because it will not send the same notification to all users. But there is no process behind the scenes so that it will not be run automatically, the problem is overcome by using AJAX by retrieving JSON and then running repeatedly on the web browser and minimizing clashes between web push notification scripts on multi tab windows or web browser windows resolved using localStorage from the HTML5 WebStorage API. The test results show that the application of Web Push Notification technology in the Archive Management Information System can help users manage many archives and use AJAX influences the speed of web access.

Visualization mechanisms for constructing terminological clouds are considered. An example of JSON, HTML, CSV, XLSX, XML, TXT is a list of file types and resources. Possibilities of extraction and storage of input data are analyzed. Studies of similar systems were performed, on the basis of which two optimal file types were selected, namely CSV and TXT. The approach of forming a list of keywords for scholarly publications or distinguishing the leading topics of different texts was discovered. If the need is to handle large collaborative texts, such as literary works, scientific articles, judgments, etc., it will be sufficient to use small web applications to build tag clouds. K-mean tag clouds are able to effectively identify key concepts, most commonly used words, and leading concepts. When comparing CSV and TXT formats, it was confirmed that the processing speed depends more on the amount of input than on the file structure. Hence, it can be argued that the use of one or the other format is conditioned by the user's choice. An analysis has been conducted that noted that the CSV format needs an upper line that specifies attributes. For the sake of correctness of the further analysis, the attributes should be specified and formed each successive row of data in strict order. Such a slight feature of the structure helps the researcher to navigate among the set of textual information, and in further processing the first line can be ignored. Unlike the previous format, the TXT format does not require the formation of the first line of attributes. This complicates the visual perception of the information available. It is not recommended to enter the attributes yourself, in the future, when processing it will affect the correctness of the clustering results in the negative. [ABSTRACT FROM AUTHOR]

The problem of incorrect and outdated interpretation of the library activity, as well as its positioning in the modern world, is considered. Compiled information model of the future of software, that is the goal and the means by which the system can operate for achieving this goal and that is demanding these features, so they can be used. According to the results of the research, in order to systematize the modern view of the library, it was decided to implement the Library 3.0 standard, which, in turn, is responsible for modernizing the form of library services using such technologies as semantic network, cloud services, mobile devices, in the scientific- technical library. Library 3.0 is the standard that is responsible for the electronic systematization of services that ensure the life of the academic library through communication between departments and the user. At the moment, this is the most exciting achievement in the research and development of higher education libraries, as the standard presented emphasizes context, not just the means of providing information services. A thorough analysis was carried out on the basis of existing methodologies and approaches to create the conceptual model of the project, basic principles and principles of software development, auxiliary parameters and tools for achieving the desired result, analytical data. A web resource was developed to present the Library of Science and Technology ONAHT on Library 3.0 principles, taking into account the latest Web 2.0 capabilities. [ABSTRACT FROM AUTHOR]

In a microservice architecture aggregation of data collected from different sources is a common task. Today's technology trends require us to exchange data that is no longer tabular. JSON data format has gained popularity among web developers, and has become the main format for exchanging information over the web. When we need to aggregate data collected from the web, storing it into relational database just to perform this task and pass it to the next unit to process or display it often is an exaggerated action. In this paper, we discuss a scenario and an implementation of in-memory preprocessing and aggregating data using lazy evaluation, value tuples and LINQ. [ABSTRACT FROM AUTHOR]

The US Department of Veterans Affairs has been acquiring store and forward digital diabetic retinopathy surveillance retinal fundus images for remote reading since 2007. There are 900+ retinal cameras at 756 acquisition sites. These images are manually read remotely at 134 sites. A total of 2.1 million studies have been performed in the teleretinal imaging program. The human workload for reading images is rapidly growing. It would be ideal to develop an automated computer algorithm that detects multiple eye diseases as this would help standardize interpretations and improve efficiency of the image readers. Deep learning algorithms for detection of diabetic retinopathy in retinal fundus photographs have been developed and there are needs for additional image data to validate this work. To further this research, the Atlanta VA Health Care System (VAHCS) has extracted 112,000 DICOM diabetic retinopathy surveillance images (13,000 studies) that can be subsequently used for the validation of automated algorithms. An extensive amount of associated clinical information was added to the DICOM header of each exported image to facilitate correlation of the image with the patient's medical condition. The clinical information was saved as a JSON object and stored in a single Unlimited Text (VR = UT) DICOM data element. This paper describes the methodology used for this project and the results of applying this methodology. [ABSTRACT FROM AUTHOR]

There are several frameworks that can be used to make create applications easier in the Java programming environment, whether in web applications or desktop applications. If we focus more on Java web framework, there is Spring Framework that has been popular since 2004, especially with the ability of Spring Framework which can be combined with various other frameworks such as Hibernate Framework, Ibatis or namely MyBatis Framework today and several other frameworks. This research was conducted in comparing ability of data loading from a web service application built using the Java programming language with the Spring Framework, especially if combined with Database Bridging Layer such as Java Database Connection (JDBC), Hibernate Framework, MyBatis Framework, plus additional framework capabilities contained at Hibernate and MyBatis that have as cache data layer. Performance test scenario create a web service in Spring Framework then accessed by custom test script built with third party code and call it repeatedly with a certain time period.

In recent years, JSON established itself as a very popular data format for representing massive data collections. JSON data collections are usually schemaless. While this ensures several advantages, the absence of schema information has important negative consequences as well: Data analysts and programmers cannot exploit a schema for a reliable description of the structure of the dataset, the correctness of complex queries and programs cannot be statically checked, and many schema-based optimizations are not possible. In this paper, we deal with the problem of inferring a schema from massive JSON datasets. We first identify a JSON type language which is simple and, at the same time, expressive enough to capture irregularities and to give complete structural information about input data. We then present our contributions, which are the design of a parametric and parallelizable schema inference algorithm, its theoretical study, and its implementation based on Spark, enabling reasonable schema inference time for massive collections. Our algorithm is parametric as the analyst can specify a parameter determining the level of precision and conciseness of the inferred schema. Finally, we report about an experimental analysis showing the effectiveness of our approach in terms of execution time, conciseness of inferred schemas, and scalability. [ABSTRACT FROM AUTHOR]

At a time when large amounts of data are being poured out, there are many changes in software architecture or data storage patterns because of the nature of the data being written, rather more read-intensive than writing. Accordingly, in this paper, the query model of Command Query Responsibility Segmentation (CQRS) pattern separating the responsibilities of commands and queries is used to implement an efficient high-capacity data lookup system in users' requirements. This paper uses the 2018 temperature, humidity and precipitation data of the Korea Meteorological Administration Open API to store about 2.3 billion data suitable for RDBMS (PostgreSQL) and NoSQL (MongoDB). It also compares and analyzes the performance of systems with CQRS pattern applied from the perspective of the web server (Web Server) implemented and systems without CQRS pattern, the storage structure performance of each database, and the performance corresponding to the data processing characteristics.

Summary: Cloud computing and its service models, such as Platform as a Service (PaaS), have changed the way that computing resources are allocated to Information and Communications Technology enterprises and users. Although multiple cloud providers support dynamic service provisioning, it is necessary to facilitate the management of the cloud infrastructure and applications in order to allow the continuous refinement of cloud models. Therefore, issues are raised regarding the cloud orchestration, including the flexible portability and interoperability of cloud applications among multiple cloud providers. Having said that, there is a need for a standardized design and management of the cloud use cases (during the creation of scenarios, application's deployment, and patching) to ensure efficient applications' migration between different providers. This paper proposes an artifact, GITS, a generic input template for CloudSim and other cloud simulators. GITS can be provided by PaaS offering to manage the creation, monitoring, administration, and patching of infrastructure and applications in the cloud. GITS defines the cloud schema that can be used with conforming cloud models and independent cloud providers; thus, portability and interoperability can be enabled in PaaS cloud models. GITS focuses on the architecture‐based modeling for cloud infrastructure and application not only in terms of computational resources but also in terms of high availability properties associated with infrastructure and applications. The main objective of the GITS template is to provide the cloud user with a modular, simple, readable, and reusable model that still supports the essential components and provide them with the ability to control the applications' execution, deployment, and other management needs in addition to the allocation environment. This paper describes GITS usage, specifically as an input template for CloudSim. [ABSTRACT FROM AUTHOR]

This article investigates the possibility of logical structure (abstract syntax tree) automatic construction for text documents, the format of which is not fully defined by standards or other rules common to all the documents. In contrast to the syntax described by formal grammars, in such cases there is no way to build the parser automatically. Text files in LATEX format are the typical examples of such formatted documents with not completely formalized syntax markup. They are used as the resources for the implementation of the algorithms developed in this work. The relevance of LATEX document analysis is due to the fact that many scientific publishings and conferences use LATEX typesetting system, and this gives rise to important applied task of automation for categorization, correction, comparison, statistics collection, rendering for WEB, etc. The parsing of documents in format requires additional information about styles: symbols, commands and environments. A method to describe them in JSON format is proposed in this work. It allows to specify not only the information necessary to pars, but also meta information that facilitates further data mining. And it is really necessary, for example, for correct comparison of documents, which arises in the solution of the automatic correction problem. This approach is used for the first time. The developed algorithms for constructing a syntax tree of a document in LATEX format, that use such information as an external parameter are described. The results are successfully applied in the tasks of comparison, auto-correction and categorization of scientific papers. The implementation of the developed algorithms is available as a set of libraries released under the LGPLv3. The key features of the proposed approach are: flexibility (within the framework of the problem) and simplicity of parameter descriptions. The proposed approach allows to solve the problem of parsing documents in LATEX format. But it is required to form th- base of style element descriptions for widespread practical use of the developed algorithms.

Interoperability among heterogeneous devices is one of the main topics investigated nowadays to realize the Ubiquitous Computing vision. Smart-M3 is a software architecture born to provide interoperability through the Semantic Web technologies and reactivity thanks to the publish-subscribe paradigm. In this paper we present a new implementation in Python of the central component of the Smart-M3 architecture: the Semantic Information Broker (SIB). The new component, named pySIB, has been specifically designed for embedded or resource constrained devices. pySIB represents a new open source lightweight and portable SIB implementation, but also introduces new features and interesting performances. JSON has been introduced as the default information encoding notation as it offers the flexibility of XML with minor bandwidth requirements. Memory allocation on disk and at runtime is in the order of Kilobytes i.e. minimal, if compared with the other reference implementations. Performance tests on existing (SP2B) and ad-hoc benchmarks point out possible improvements but also encouraging data such as the best insertion time among the existing SIB implementations.
