One of the fastest 3D data acquisition methods is LiDAR scanning technology. By using LiDAR scanners, 3D point clouds of the scanned seen is obtained easily. Although the scanning phase is fast, the meaningful and effective 3D visualization of the scene requir…

It is important to determine the initial level of failures of induction motors used in many industrial applications. The sudden stops of the system can be prevented with the pre-detection of the fault. The experiment mechanism was established to detect mechani…

Hydrological drought is one of the most essential natural hazards attributing water scarcity and its global impact increases due to the climate change. In particular, the usage of climate models and rainfall-runoff models for projecting the severity of future …

Differential evolution algorithm (DEA) is one featured kind of population based evolutionary algorithms. Although it is stated in previous studies that the algorithm is more sensitive to the crossover rate, it is tried out in this study whether DEA depends on …

Günümüzde gelişen teknolojiyle birlikte artan sera gazı emisyonları ve küresel ısınma problemleri yenilenebilir enerji kaynaklarının kullanımını önemli ölçüde artırmıştır. Yenilenebilir enerji kaynakları güneş enerjisi, rüzgar enerjisi, jeotermal enerji, hidro…

Bu çalışmada kokil kalıba döküm yöntemiyle üretilen Zn-15Al-3Cu-1Si alaşımına T5 ve T7 ısıl işlemleri uygulandı. Alaşımın dökülmüş ve ısıl işlem görmüş durumlardaki numunelerinin içyapıları taramalı elektron mikroskobu (SEM) ve enerji dispersif spektrometresi …

Günümüzde ahşap malzeme hayatımızın her alanında kullanılmakta olup, sürekli kullanımdaki tercih edilebilirliği devam eden bir malzeme olarak karşımıza çıkmakta ve ahşap malzemenin önemini daha da arttırmaktadır. Yangın her zaman yaşadığımız ortamda meydana ge…

The developments in internal combustion spark ignition (gasoline) engine technologies are in line with emission standards. The conversion systems which enable the use of LPG fuel in spark ignition (gasoline) engines renew themselves according to the developmen…

Bu çalışmada, non-lineer ve dengesiz yükün bulunduğu güç sisteminde aktif filtre kullanılarak harmonik distorsiyonun değeri düşürülmüştür. Pasif harmonik filtrelerin aksine, modern aktif harmonik filtreler, güç faktörü düzeltme, gerilim regülasyonunu saglama…

Tencel lifi sürdürülebilir hasat edilmiş okaliptüs ağaçlarından organik çözücü kullanılarak elde edilmekte ve sahip olduğu yüksek mukavemet ve konfor özellikleri sebebiyle günümüzde tekstil ürünlerinde kullanımı gittikçe artmaktadır. Tencel ile ilgili çalışm…

Tek Fazlı Şebeke Kalkışlı Sabit Mıknatıslı Senkron motorlar (TF-ŞKSM) günümüz endüstrisinde kullanılan standart indüksiyon motorlarına göre özellikle küçük boyutlarda daha yüksek verimlilik sunabilmektedirler. Verimliliğin artması çevre üzerindeki olumsuz et…

Multi-seeded YBCO superconductors (cylindrical size) 32 mm in diameter were fabricated by top-seeded melt growth (TSMG). Melt-processing was performed using a precursor containing 75 wt % of Y123 and 25 wt % of Y211 with 0.5 wt % of CeO2. Trapped magnetic fi…

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…

Today, rapid population growth and the development of technology have brought about the problem of waste. In order to solve this problem, it is first necessary to reduce the waste generation at the source. This can be achieved by raising awareness of the consu…

Nowadays the progress of technology; computers, the internet and smartphones have taken over our lives and made an important place in our lives. Turkstat to be made according to the Household Survey on Information Technology Usage in Turkey, 96.9% of household…

Molecular interactions have been a hot topic in chemistry because of their importance in different processes from biological activities [1]. Quantum dots with strong and easily tunable luminescence and high emission quantum yields have become well-established …

Due to increase in heating rate of initial powders used for production of aluminium matrix composites in sintering furnace, both formation of undesired phases in content of the composite materials were prevented and production costs and duration were tried to …
