The purpose of the research was to propound an insulin activity model in a human body after a subcutaneous injection. A deterministic model in the form of a mathematical function was formulated. The research was based on pharmaceutic publicly available drug information published by the manufactures. The paper presents in detail the model. The obtained results can be used in computer simulations of diabetes mellitus therapy. They suggest that activity models may be assigned to types of insulin instead of separate products.

The primary purpose of this paper is to present and provide main advantages and disadvantages of most popular big data platforms as well as their comparison in terms of ease of installation, work, performance and price, in order to find the most suitable solution to work with big sets of data. Nowadays, the data is largely analyzed by scientists not related to IT, so the ease of use and presentation of data is extremely important. The purpose of the assessment was to indicate the best IT tool for analyzing data from the point of view of a young analyst or scientist graduating and entering the labor market.

The subject reached in the article is to check the performance of the Symfony framework for creating web applications. An overview of the literature about Symfony and the most popular modules. Based on the created three identical test applications written in the Symfony 2.8, 3.4 and 4.2 frameworks, they were compared with each other in terms of performance. The test application was written in the blog format. The software architecture style known as the API has been used. Related to this, it is possible to conduct scheduled tests. Symfony's performance testing for individual versions was based on, the time of loading data from the database and their search in the data collection, additional tests were to download data from a csv file and save them to a csv file.

The following paper presents the results of research on the impact of machine learning in the construction of a voice-controlled interface. Two different models were used for the analysys: a feedforward neural network containing one hidden layer and a more complicated convolutional neural network. What is more, a comparison of the applied models was presented. This comparison was performed in terms of quality and the course of training.

The aim of this paper is a comparative analysis of frameworks for designing corporate applications. For analytic reasons the application for document circulation within a law firm was designed. The presented comparative analysis includes TOGAF framework as well as Zachman framework. The analysis was conducted on group of experts based on evaluation criteria divided on several groups. Five groups of criteria were defined: implementation, testing, time-consuming, documentation and schedule planning. As the research shows, Zachman framework presents a versatile approach towards designing corporate architecture, because it presents not only the client’s vision but also the visions of a designer and a programmer, whereas TOGAF framework focuses mainly on business approach regarding aims and strategy of an enterprise. The aforementioned research was carried out on a group on a two domain experts.

The article describes the impact of using WebAssembly on the performance of web applications. A Blazor framework based on WebAssembly was used. The paper shows that it is possible to create fully functioning Single Page Application using C# programming language. The second application was made using Angular framework. Both applications implement the same functionalities. For prepared applications loading time and size of transferred data was measured. The impact of using browser cache memory and gzip compression was examined. The performance of handling http requests using GET and POST methods were measured. The performance of WebAssembly against JavaScript code in task of sorting a list of N objects was compared. The performance of modifying html DOM was examined. Selected code metrics of written applications were compared. JavaScript presents better performance with tasks related with browser API. WebAssembly was better for computing.

This article presents the results of the performance studies of applications created with use of CryEngine and Unity game engines. Presented research was mainly focused on comparison of two applications created on selected engines. Several parameters were selected for the research: frame rate, CPU usage, RAM usage and generation time of 3D objects. Created applications were built with the use of the same graphic resources and similar source code. The hypotheses set in the article – Unity game engine is more efficient than CryEngine – have been verified and partially confirmed: engines are more efficient in different environments.

This publication presents the results of a comparative analysis of Java and Kotlin programming languages used to create mobile applications for system Android. The analysis covers performance aspects such as CPU load, RAM load, as well as the compilation and execution times. Aspects such as code structure, availability of libraries, supported databases, popularity and community support were taken under consolidation.
