Abstract
The demand for community involvement during the planning process is growing. Kosovo, to be in step with global development trends in the field of planning, has developed various projects in the name of public participation. The pilot project for the Brekoci informal settlement in Gjakova is an example of community-based planning. The purpose of this paper is to show the way of community involvement through unique methods explicitly designed for this community, as the tool “Express”, “Mark” and “Vote” and how the data obtained from these tools through spatial systems as Geographical Information System and DepthMapX, have generated the community's vision, which has resulted in the drafting of the urban regulatory plan. This plan represents a reflection of the local cultural context.
Abstract
Public space is the most important place for social life, but it is also part of the identity of the local community. This is particularly true in Komló, where the mining past is still a perceptible and integral part of local identity. Petőfi Square is the central square of Komló's Kökönyös district, an urban district center that preserves the memories of its past, but has not evolved with changing needs in the city for some time. The renewal of Petőfi Square and its surroundings was an environmental architecture task that built on local values, responded to the needs of local people and helped the development of community life, and had to cope with a number of parallel demands.
Abstract

The aim of this work is to establish universal graphical dependencies and empirical formulas for describing velocity and temperature fields over the entire range of development of round convective exhaust ventilation jet; development of an algorithm for solving the transcendent problem of determining the surface temperature of a heat source; introduction of velocity and temperature attenuation coefficients for round convective jet; visualization of its characteristics in the form of a 3D image; achieving reduction of metal consumption of the local exhaust ventilation system due to the overall optimization of the velocity and temperature fields of the round convective air jet.
Abstract
Development of control of a five degrees of freedom robot is discussed in this paper. Only two robots were made, and one of these is in the University of Miskolc. The robot was made in the 80s for educational purposes, the electronic components were obsolete and control software was missing, therefore it became necessary to perform hardware improvements, and develop a new control program. Inverse kinematics problem of the robot is solved by geometric approach to formulate the joint angles, which will form the basis of the control. A braking system containing electromagnets for the robot is constructed to balance it. A printed circuit board is designed to establish the control of the system, the central element is a Cypress PSoC 5LP platform. The development of the control program is performed in software PSoC Creator 4.4. The developed control system of the robot can receive instructions from a computer via a designed special purpose user program, which is written in Python programming language. Thanks to the improvements, the robot has become operational. Thus, the robot can serve educational purposes performing different manipulation tasks. By completing the developments, students can get to know the structure and programming of the robot, its inverse kinematics problem. This will require the development of practice-oriented tasks in the future.
Abstract
The article is devoted to solving of urgent problem: creation of staff work safety in the boiler room due to ensure of required conditions by natural ventilation. The aim of the work is to eliminate the main damage of the natural ventilation system of the boiler premise by using of compact air jet due to correction coefficients and updated results. Static and dynamic air pressure, difference of static pressure due to wind, aerodynamic coefficients and air balance for necessary nature ventilation of the boiler premise as well temperature correction coefficient are established. The update calculation dependencies for determining of the air static pressure and its volume flow rate in the boiler room have been obtained. Updated graph, monogram, and analytical equations for natural ventilation calculation of boiler room are presented.
Abstract
All the available information and uncertainties should be taken into account in a model to give correct answer to a stated problem and evaluate the performance of a structure. This study deals with the impact of parameter estimation uncertainty in extreme wind speeds on the assessed reliability index using frequentist approach. The peak-over-threshold approach with an automated threshold selection method is applied and bootstrapping is used to determine the 95% confidence interval of the estimated reliability index. Based on the results practical recommendations, i.e., a framework of this procedure are derived on how to handle peak-over-threshold in extreme wind speed models for the application of the proposed performance-based wind engineering design.
Abstract
In mechatronic-related applications, estimating orientation from a magnetic, angular rate, and gravity (MARG) sensor array is a significant topic. Representing attitude orientation is a well-known topic in the aerospace industry, where it plays a critical role in airplanes and unmanned aerial vehicles (UAVs), but it has also gained relevance in other sectors. However, most of the sensors utilized are quite expensive, heavy, and large, making them unsuitable for modest applications. This paper examines the performance of several sensors in low-cost hardware and high-acceleration environments. A theorical method was adopted to estimate Euler angles by using accelerometer, gyroscope and magnetometer, and a robust and easy to implement method calibration was proposed to calibrate the MARG sensor without any external equipment. An experimental verification of the proposed calibration method was completed. The experimental results are then interpreted to provide an insight to advantages and disadvantages for using each sensor separately.
Abstract
This study evaluated the possibility of producing innovative glass-ceramic foams from zeolite-poor rock (Tokaj, Hungary) using alkali-activation and reactive sintering techniques. The composition and morphology of the samples were studied using X-ray diffraction, X-ray fluorescence, scanning electron microscope, and computed tomography techniques. The influence of various sintering temperatures on glass-ceramic foams was examined. It has been observed that zeolite-poor rock has a self-foaming capability. The heat treatment temperature affects the pore size and distribution as well as the technical characteristics of the obtained samples. The resulting glass-ceramic foams possess moderate thermal conductivity ranging from 0.11 to 0.17 W mK−1 and good compressive strength (1.5–4.4 MPa). The produced samples might be utilized for thermal insulation, which would have both economic and environmental advantages.
Abstract
In this paper, advanced DC-Link (DCL) based reversing voltage type Multilevel Inverter (MLI) topologies by compensating the difficulties in the conventional MLIs are reviewed. These topologies consist of less switching components and driver circuits when compared with conventional MLIs predominantly in higher levels. Consequently, installation area, total cost and hardware difficulties are reduced by increasing the voltage levels. The unipolar based Pulse Width Modulation Schemes (PWMS) will improve DCL inverters performance. This paper presents unipolar Multi-Reference (MR) based sine and space vector PWMS with single triangular carrier wave for generating required levels in output voltage. Comparison between UMR sine and space vector PWMS for DCL inverter topologies is presented in terms of Fundamental Output Voltage (FOV) and Total Harmonic Distortion (THD). The research tries to establish the survey analysis for single-phase 7-level DCL based reversing voltage type MLI topologies with UMR based sine and space vector PWMs. Finally, to confirm the feasibility of proposed DCL-MLIs in terms of FOV and THD the simulation results are incorporated. Further, the prototype model is developed for single-phase 7-level DCL inverter with Field Programmable Gate Array (FPGA) based UMR sine and space vector PWMS to authenticate simulation results. The efficiency of the proposed cascaded MLI achieves the value of 99.003%.
Abstract
Public green spaces are very important in the urban structure, both on environmental and social level. Renovation may be necessary, but the process must involve complexity.
The objective of this research is to define the main criteria of a successful renovation process, using two case studies - the Lucius-Burckhardt-Platz in Kassel, Germany, and the ‘Parku i lodrave’ in the city of Peja, Kosovo, where the recent intervention had rather negative effects. The paper considered aspects as community activity, key functions, visual elements, accessibility, safety, well-being and maintenance.
The transformation of these spontaneously developed, liveable spaces into renewed but abandoned parks was explained by the lack of correlation between the analysis of function, public needs, and the dominance of aesthetics.
