Decisive Factors for IT Ecosystem Development in Moravica District, Serbia

2024-01-19T10:20:31+00:00

The research presents the role of the Information Technology study program, offered at the Faculty of Technical Sciences Čačak, in the development of the IT ecosystem in the Moravica District in Serbia. The data were collected on the companies and their employees, as well as on the percentage of the students and graduates of the mentioned study program in these companies. The correlation between the growth of the number of companies and the development of the study program was measured and the Pearson's coefficient (0.755) was calculated, which points to the existence of a strong relationship between the number of students enrolled in the IT study program and the number of IT companies in the Moravica District. Future work relates to further monitoring of the IT ecosystem and improvement of the study program following the market needs.

Multi-criteria Analysis of Need Factors for Developing a Machine Learning-based System to Track Employees' Digital Activity

2024-01-19T10:19:58+00:00

The necessity of developing a system for Machine Learning (ML)-based employee digital activity monitoring is examined in this study. The need for developing and using ML-based remote employee monitoring systems in companies is assessed using the benefits associated with them. The development of such a system would require the application of suitable prediction models in addition to Machine learning methodologies and techniques. A Multi-criteria analysis is carried out on a sample of 102 superiors from IT (53 respondents) and non-IT (49 respondents) companies that allow their employees to work remotely, in order to determine the necessity of developing such a system. Applying the Multi-criteria Analytic Hierarchy Process (AHP), it is seen that among the respondents from IT companies, the enhancement of remote employees' job quality is the most significant factor for the development and deployment of this type of system. Conversely, non-IT respondents highlighted increased employee productivity as the primary advantage of the system implementation.

2024-01-19T10:19:21+00:00

This paper is focused to the emerging technological development in the area of the advanced vehicular communication systems. It considers the most up to date Vehicular to Everything technologies and discusses the typical scenarios related to the communication between vehicles, between vehicles and infrastructure, vehicles and pedestrians and communication between vehicles and network environment. Paper also considers the arising issues and countermeasures related to the security, privacy and quality of service (QoS) as well as predictive QoS aspects.

HTTP Embedded Web Server and its Application for Air Parameters Monitoring

2024-01-19T09:54:47+00:00

Embedded systems find extensive applications in various aspects of daily life and their presence in the highly connected world of today is growing. With a large number of remote devices and sensors, there is a growing need for remote data processing. Microcontrollers, often integral components of such devices, can enable remote data manipulation through the implementation of a web server called embedded web servers. The implementation of a server on such a system poses challenges, such as limited resources, so it is crucial for the web server implementation to be compatible with the available resources. This paper focuses on the requirements for the implementation of a web server. Also, an embedded web server has been designed for specific application of monitoring air parameters. The implementation utilizes the LwIP stack and allows for remote access to measurement results within a local network. The paper will delve into the operational principles of both the web server and the entire system.

Thermal and Mechanical Piston Influence on Photoacoustic Signal

2024-01-19T10:16:21+00:00

In this work, the influence of the thermal and mechanical piston effects over the frequency at which the amplitudes of the components of the photoacoustic signal resulting from these two effects are equalized. The analysis was done in the measuring range 10 to 20kHz. An aluminum sample illuminated with modulated light, whose thickness varies from 10 to 1000 microns, was considered.
