Contribution to the Research on New Belgrade: The Unbuilt Projects and the Concepts of Nikola Dobrović

<p class="Abstract" style="text-align: justify;"><span lang="sr-Cyrl-BA" style="mso-fareast-language: BS-LATN-BA;">Architect Nikola Dobrović is best known in Serbia for his only constructed building in Belgrade, the complex of the State Secretariat of National Defense (DSNO), better known as the General Staff, today an endangered cultural heritage and a crumbling building with an uncertain future. However, his short-term engagement as the head of the Urban Planning Institute of the Republic of Serbia from 1946-1947, and his later professorship at the Faculty of Architecture University of Belgrade, are equally significant for Belgrade and Serbia. Documents testifying to the post-war period of his work are scattered in several places: in the Urban Planning Institute of Belgrade, the Museum of Science and Technology, the Historical Archive of Belgrade, and the rare publications can only be found in a few libraries in Serbia. In the course of his short-term work on New Belgrade, Dobrović provided several conceptual projects and sketches for New Belgrade within the Urban Planning Institute: the perfomance square, road schemes and the urban planning solution of the zone between the Palace of the Federation and the Railway Station - today's Central Zone of New Belgrade. Finally, at different stages of his career, Dobrović also designed individual objects, such as the project for the Faculty of Electrical Engineering and the building of the Central Committee of the Communist Party of Yugoslavia, which remained in the domain of 'paper architecture', unbuilt, and which provides an insight into the way he thought about the process of urban and spatial planning, through the positioning of builidngs which would've generated the character of their immediate and distant surroundings.</span></p>

TEHNOLOŠKI NAPREDAK I KLIMATSKE PROMJENE – TEMA U OBRAZOVANJU INŽENJERA / TECHNOLOGICAL PROGRESS AND CLIMATE CHANGE – TOPIC IN ENGINEERING EDUCATION

At the beginning of the 21st century, environmental issues became leaders in all areas of human activity without competition. All other essential topics: health, food, energy, water, and air, are predominantly determined by environmental problems. Climate change is a result of excessive CO2 emissions due to the greenhouse effect, air pollution as a result of emissions of harmful substances by thermal power plants, chemical plants, heating boilers, individual furnaces, means of transport; pollution of drinking water, pollution and devastation of arable land, destruction of forests, pollution of rivers due to inadequate wastewater treatment, etc. are problems that require a radical change in man's attitude towards the environment, which leads to the need to reconsider and change the current way of doing business. The paper analyzes the impact of scientific achievements in electrical engineering on the accelerated industrial growth that has led to today's environmental problems. Industrial development is explored in phases (Industry 1.0, Industry 2.0, Industry 3.0, Industry 4.0) regarding the impact of radical changes in doing business. Since we are now in phase 4, the dominant topics are energy transition, energy efficiency, renewable energy sources, recycling, innovation, electric vehicles, networking, Internet of Things (IoT), artificial intelligence, and 5G. Although all the above topics are multidisciplinary, a significant share of electrical engineering is clear. Existing plans and programs in electrical engineering, whether based on the traditional model of education or in the process of innovation, are adapted to new technological trends. As a rule, little or no importance is attached to environmental issues. As one of the answers to the mentioned problem at the Faculty of Electrical Engineering, University of Sarajevo, a new course, “Sustainable Development” was included. The paper briefly describes the content of this course.

Development and laboratory testing of a lightning current measurement system for wind turbines

Dimensioning, testing and maintenance of the lightning protection system of wind turbines can be improved using the local distributions of lightning current parameters instead of those on which lightning protection standards rely. This paper presents a prototype system for measuring lightning currents’ waveforms on wind turbines. The prototype is being developed at the Faculty of Electrical Engineering and Computing, University of Zagreb, Croatia. The system's fundamental components are two Rogowski coils and their corresponding integrators. One coil is optimized for lower frequencies and amplitudes, while the other is for higher ones. The cRIO real-time controller is used as an acquisition system, with acquisition logic developed using LabVIEW. The controller has one digitizer for each coil and a GPS synchronization module. The system was tested in the High Voltage Laboratory at University. It was recently installed on an actual wind turbine in Croatia, located in an area characterized by high winter lightning activity. Simultaneously with the prototype measurement system, the lightning activity in the wind turbine micro-location will be monitored by three other systems: the lightning location system, additional lightning monitoring sensors installed in the blades of the same wind turbine and a high-speed camera installed at the wind turbine location.

Prevalence of Hookah Smoking and its Associated Factors among Undergraduate Engineering Students of Khwopa College of Engineering, Nepal

Background: Hookah smoking, also known as water pipe smoking, is an emerging trend that is gaining popularity globally, especially among youth and college students. It has been referred to as a global tobacco epidemic by public health officials and identified as an emerging threat to public health. Methodology: A descriptive cross-sectional study with systematic sampling was conducted. A self-administered questionnaire was used to collect the data. Collected data were entered, and analysis was done using SPSS IBM version 26. Results: The overall prevalence of hookah smoking was found to be 38.7%, with a mean age of 17.92 years. The analysis indicated that sex and faculty of respondents were significantly associated with hookah smoking. In this study, male participants were 2.44 times more likely to be involved in hookah smoking compared to female participants (OR=2.449, 95% CI=1.026–0.848). Participants in the electrical engineering faculty were 4.84 times more likely to smoke hookah than participants in the computer engineering faculty (OR=4.844, 95% CI), and participants in the civil engineering faculty were 2.58 times more likely to smoke hookah than participants in the computer engineering (OR=2.583, 95% CI). Conclusion: The cross-sectional study with systematic sampling conducted among undergraduate engineering students at Khowpa College of Engineering revealed that hookah smoking was more prevalent among male participants than female participants. Hence, an awareness program is needed to be planned and implemented among engineering students, with a special focus on male students.

The PLC and HMI communicate via PROFINET. The battery storage units are installed in Smart Grid Laboratory (SGLab) at the University of Zagreb Faculty of Electrical Engineering and Computing.

Influence of Environmental Factors on the Intelligent Management of Photovoltaic and Wind Sections in a Hybrid Power Plant

The high-efficiency operation of photovoltaic and wind systems is affected by many factors and parameters that should be continuously monitored. Since most of the variable factors are related to weather conditions, they are difficult to predict. Therefore, in order to optimize the operating point of a photovoltaic or wind power plant, it is necessary to observe changes in the subject area. The operation of photovoltaic and wind power plants can complement each other. The results recorded at the hybrid power plant of the Faculty of Electrical Engineering of Bialystok University of Technology are useful for a comprehensive analysis of the power plant operation and the ways to optimize it. This paper presents the influence of environmental factors on the operation of a hybrid photo-voltaic–wind power plant located in the city of Bialystok, Poland. The aim of the study was to present the variable factors on the optimal adjustment of the location of the power plant elements at the stage of its design and selection of the energy management system. The presented measurement data from 2015–2021 allow conclusions to be drawn on the significant impact on the power plant’s operation, taking into account both the average conditions corresponding to the analysed location and the full range of changes in the listed factors.

"ADAPTATION PROBLEMS OF ROMANIAN STUDENTS TO TECHNICAL HIGHER EDUCATION"

The current study underlines the main problems students deal with in the first academic year at University POLITEHNICA of Timişoara (UPT) while adjusting to the higher education environment.
