Interior lighting profoundly affects health, perception, and comfort. This study investigates key lighting parameters—intensity, spectrum, exposure timing, and spatial layout—and their physiological and psychological effects. Based on scenario simulations, thi…
Bir şehrin gece manzarası, o şehrin gece boyunca yeniden tanıtılması olarak değerlendirilebilmektedir. Hatta kimi zaman gece manzarası insanların şehir hakkındaki düşünceleri üzerinde daha fazla etki bırakabilmektedir. Karanlık bir manzara deneyimi fikri, yum…
LEDs that emit blue light are needed to create white light using LEDs. In 1991, Japanese scientists Isamu Akasaki, Hirochi Amano and Shuji Nakamura invented LEDs that emit blue light. From this date it became possible to use the LEDs as lighting elements. Rapi…
Çalışmamızda Samsung PLCC4 LED ve elektronik bileşenlerinin jonksiyon sıcaklığı üzerinde via etkisi hesaplamalı akışkanlar mekaniği analizleri ile araştırılmıştır. Analizlerde FloEFD 17.4 hesaplamalı akışkanlar dinamiği ticari programı kullanılmıştır. Elektron…
For a successful thermal performance, the right choice and design of the thermal management materials used in LED die-moulding, cooler and soldered parts is a critical engineering problem. Because they are affected by heat emitted from the pn junction in the L…
Building automation and control systems (BACs) allow plants in buildings to be controlled and managed, thus increasing the users' comfort and reducing the operation and maintenance costs. As far as the lighting services are concerned, control systems offer an …
Scientific and technical field of multiple disciplines working on lighting, is of great importance in our daily lives. Especially when energy saving is aimed at illumination of houses, other elements are mostly ignored. This situation, which affects our physic…
Enerji verimliliği alanındaki çalışmalar hız kesmeden artarken insanların konfor beklentileri de her geçen gün daha fazla yükselmektedir. Bununla birlikte, akıllı binaların sayısı da teknolojik gelişmelere paralel olarak artmaktadır. Günümüzde akıllı binalar h…
Energy demand in the 21st century is increasing continually. This increase in energy demand is one of the factors affecting the increase in universal problems. Energy is produced using both renewable and non-renewable resources. Therefore, energy consumption…
The collective system, which includes the automation system, data exchanges and production technologies is referred to as Industry 4.0. This system has two main components. The first is the new generation of software and hardware, and the second is the cyber p…
Few ancient structures inspire spiritual reverence and architectural awe like the Roman Pantheon. Designed as a temple and a cosmological instrument, the Pantheon depicts how Roman architects transformed daylight into a divine symbol. This paper examines the s…
The popularity of wireless communication is increasing day by day. This has led to the fact that data transfers via GSM have reached very high levels. Data transfers via GSM, which are continuously growing, increase the density of data traffic, thus necessitat…
Energy is at the forefront of the needs to maintain the continuity of life and make it easier, and the energy demand is increasingly dependent on population growth. Today, fossil energy resources are widely used to meet energy demand and renewable energy resou…
Here we discussed the electrical performance of Photovoltaic (PV) panels of natural dust accumulation by wind, bird droppings etc., over time which is of great importance especially for the areas where the rain density are high [1, 2]. In this study, the eff…
Solar photovoltaic (PV) systems are widely adopted for sustainable energy production; however, physical defects such as glass breakage significantly reduce panel efficiency and system output. In this study, a real-world case analysis was conducted on a 1003 kW…
Developing technology, and electronic devices, power consumption is increasing day by day. At the present time, there are many methods used to generate electricity. Most of these methods cause environmental pollution. The share of thermal power plants in elect…
Data Envelopment Analysis (DEA) is a non-parametric mathematical programming that uses multi inputs to produce multi outputs. It is investigated whether the decision making unit is effective or not. However, it has been debated for years that the results obtai…
Günümüzde, enerji ihtiyacının karşılanmasında fosil yakıtların kullanımı sınırlı kaynakları ve çevresel etkileri nedeniyle sürdürülemez hale gelmiştir. Bu durum, temiz, çevreci ve sürdürülebilir alternatiflerin, özellikle güneş, rüzgâr ve biyokütle gibi yenile…
Many situations in human life are described with uncertain narratives. The fuzzy set theory has revealed as a powerful tool to deal with the uncertainty of human thoughts and expressions, by Azerbaijani Prof. Dr. Lotfi A. Zadeh in 1965. In the classical cluste…
