Item type:Publication, Influence of the Corner Joints of the Window Frame and Sash on the Final Quality of the Window(2025-12-04); Mihajlovski, NikolaThe quality of a product is a characteristic that demonstrates how well it meets the needs for which it is intended. Given that, a window purpose is to provide light and desired ventilation to a room, while at the same time protecting the building from external influences such as air permeability, water permeability and wind resistance, we prove that it is of high quality the more it provides us with these conditions. A window as a product is a complex composition of different materials and parts. The different parts of a window include the basic structural elements, filling elements, fitting, and additional accessories. The basic structural elements of a window are the supporting frame and the window sash. The corner joints of these elements will be the target of research, in terms of how the strength of the joint of the corner segments of windows made of wooden frame, PVC frame or aluminium frame can affect the window's resistance to air permeability, water permeability and wind resistance. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, STRENGTH OF THE CORNER JOINTS OF THE WINDOW FRAME(2025-09-17); Mihajlovski, NikolaThe window as a product used in construction aims to provide natural light and the possibility for ventilation in the building where it is placed but at the same time to protect the room from external influences such as wind and rain and to prevent uncontrolled cooling or heating of the building in which it is built-in. Given the purpose, a quality window is one that protects against air permeability, water permeability and provide wind resistance. The window is a complex product that is composed of different parts that can be made of different materials. This research is focused on the area of frame joining and joint strength. This research will cover windows made from the same PVC profile but manufactured in different production facilities. The windows will be measured for air permeability, water permeability and wind resistance, and corner samples will be taken after wards. The samples are prepared according to the standard EN 514:2018 Plastics - Poly(vinyl chloride) (PVC) based profiles - Determination of the strength of welded corners and T-joints. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Al-based optimization of surface roughness in wood band sawing using polynomial regression and differential evolution(AAB College, Pristina, Kosovo, 2025-05); Jevtoska, ElenaThis study presents an artificial intelligence–assisted optimization framework for minimizing surface roughness (Rₘₐₓ) in wood band sawing. A third-order Polynomial Regression Model (PRM-3) was developed and trained on experimentally collected data obtained under varied cutting conditions, including angle, height, and feed rate. To ensure robust generalization, configurations with a 60° cutting angle were deliberately excluded from training and used solely for out-of-sample validation. PRM-3 was integrated with the Differential Evolution (DE) algorithm to identify optimal process configurations. For comparative purposes, a Gaussian Process Regression (GPR) model was also implemented to evaluate the relative generalization capability. Results confirmed the superior performance of PRM-3 in terms of accuracy, stability, and generalization, compared to GPR, demonstrating high potential for deployment in intelligent wood machining applications. The proposed framework represents a valuable integration of interpretable modeling and automated optimization for surface quality control in industrial settings - Some of the metrics are blocked by yourconsent settings

Item type:Publication, ВЛИЈАНИЕ НА СОСТАВНИТЕ ДЕЛОВИ НА ПРОЗОРЕЦОТ ВРЗ КРАЈНИОТ КВАЛИТЕТ НА ПРОЗОРЕЦОТ И ЕНЕРГЕТСКАТА ЕФИКАСНОСТ(2024-05-22)Jevtoska, ElenaПрозорецот како градежен производ има за цел на објектот да му пружи природна светлина и можност за проветрување на ентериерот, но истовремено и да ја заштити просторијата од надворешни влијанија како што се ветар и дожд како и да спречи неконтролирано ладење или греење на просторијата односно објектот во која е вграден. Со оглед на намената квалитетен прозорецот е оној кој штити од продор на воздух, продор на вода, отпорност на ветер како и неконтролирано губење на енергијата. Прозорецот е комплексен производ кој е составен од различни делови кои може да бидат направени од различни материјали. Во рамките на ова истражување ќе бидат тестирани различни видови на прозорците кои ќе дадат можност за споредба на добиените резултати со што ќе се добие податок кои составни елементи имаат влијание врз крајниот квалитет на прозорецот и врз неговата енергетска ефикасност. Основната цел е да се докаже колку изработката на прозорците, користениот профил, користениот оков, користеното стакло влијаат врз одредени делови од квалитетот на прозорецот како и врз енергетската ефикасност на прозорецот. За да се направи истражувањето ќе бидат тестирани различни прозорци согласно европските норми EN 1026:2016 (тест метода за пропустливост на воздух), EN 1027:2016 (тест метода за пропустливост на вода), EN 12211:2016 (тест метода за отпорност на ветар). Прозорците ќе бидат селектирани во различни групи кои ќе овозможат споредба на резултатите. На различни видови на прозорци со користење на различни стакло пакети ќе биде направена и математичка пресметка за коефициентот на топлоспроводливост согласно ЕN ISO 10077-1 (калкулативна метода за пресметка на топлинска пропустливост за прозорци и врати).
