The aim of the article is to compare two, most commonly used tools for the Single Page Application development. The analysis was carried out for the ReactJS library and for the Angular framework. Two applications were implemented for research purposes. The React and Angular test application has the same functionality. The comparison included the structure and performance of applications, selected code
metrics, quality of documentation and social support.
The main problem during research with a motion capture system and mobile device is lack of possibility to simultaneously begin recording on the motion capture system and a mobile device. Two methods were developed to solve this problem. In the first method the recording is started on the mobile phone and the motion capture system is notified, in the second method the motion capture system starts recording and notifies the mobile device. Both of them were compared for lags and correlation of data form the mobile device and the motion capture system.
This article discusses angle measurement accuracy assessment using inertial sensors in three-dimensional coordinate system. Vicon's acquisition system was used as a reference system. The article describes conduct of the study and application that was used for collecting data from the smartphone. The article also contains methods, formulas and algorithms that were used to compare obtained data.
This paper describes modifications of path-finding algorithms. The modifications add time and distance constraints to generated paths. A* and BFS algorithms are modified. Additionally, A* algorithm modification which combines the advantages (generating the shortest routes with the smallest number of vertices) of A* and BFS is presented.. This allows for creating a route planning app that enables users of bike sharing services to travel more easily and economically.
The presented article describes the results of a comparative analysis of methods for building applications on the Salesforce platform. The following methods were confronted with each other: object-oriented programming language Apex, Visualforce framework and Point-andclick method, which does not require writing any code. The analysis consisted in examining the performance of pages created using each method. The analyzed parameters include page load time, the amount of data that have been downloaded and the impact of the number of records displayed on the page performance.
Automated tests are designed to verify the functionality of the system at the level of the end-user interface. The article compared popular tools Selenium WebDriver and Protractor. To conduct a comparative analysis tools have been established five benchmarks under which
it was carried out the analytical hierarchy proces. Based on the obtained calculations, conclusions have been drawn regarding which platform is a better choice in terms of testing the application of the Single Page Application.
The article presents selected solutions using CPU processors and GPUs for calculations in the Matlab environment. Various methods of performing calculations on the CPU as well as on the GPU were compared. Differences, disadvantages, advantages and effects of using selected calculation methods have been indicated.
Article deals with comparison of two goggle types for virtual reality – with built-in screen and a variety of constructions with removable screen, which generally was a smartphone. For this reason research and test scenarios has been made. Its purpose was to compare those technologies in terms of quality of displaying image, ergonomics and comfort of usage.
The article presents two methods of computing calories burned during exercise. They use data obtained using sensors available on mobile devices running Android OS. These methods were compared with each other and with the results obtained from two applications available on the Google Play store. These applications are Endomondo and Sports Tracker.
The article presents multithreaded programming in selected programming languages such as: C structural and C ++ object oriented approach using Posix Threads libraries for C language and Boost library for C ++ language. The characteristics of selected libraries are also
described. Examples of typical programming problems using threads are presented. An effort was made to answer the question of what to do when choosing a language for learning multithread programming and programming in the general meaning of this word.
Today’s 3D graphics are hard to imagine without the effects known to us from film productions or high-budget video games. However, the use of such embellishments is associated with an increased demand for computing power. In order to meet the expectations of developers and consumers on the 3D applications market, tools for their creation in the form of comprehensive engines were created. One of these solutions is the Unreal Engine. The following article examines the impact on the efficiency of these effects - postprocesses. For this purpose, a test stage and two test scenarios were prepared.
The article presents an example of the use of eye-tracking technology in examining the quality of the web application interface. The subject of the research was the web part of the FastCat system, supporting the service of urban cycling races. The research methodology based on the implementation of an active experiment with users, using typical scenarios of system developed. User activities were recorded using eyetracking technology and were subjected to detailed analysis. The six-person research group had a profile analogous to potential users of the application. The final part of the article presents the results of quantitative research, a list of detected errors in the interface, as well as conclusions aimed at improving its quality.
The goal of the article is to determine the effectiveness of popular face recognition algorithms for poor quality photos. Basic facial recognition algorithms such as LBPH, Eigenfaces and Fisherfaces were described during the work. A research platform equipped with software allowing to test data and collect results was created. The results of the research showed that the only algorithm suitable for such solutions is LBPH. The others, however, did not achieve a sufficiently high effectiveness factor.
This article presents a comparision of different ways of creating PHP web applications using Laravel and CodeIgniter frameworks. The text shows differences of two implementations including ways of creation, architecture aspects and performance.
The article presents the evaluation of tools to support IT project management. The research was carried out using the diagnostic survey method on the assessment of the implementation of tools to support IT project management.
