Bu çalışmada, haberleşme cihazlarının (telefon, tablet, bilgisayar) kullanımı için ihtiyaç duyulan elektrik enerjisinin temini güneş enerjisi kullanılarak sağlanmaya çalışılmıştır. Elektrik enerjisinin olmadığı ortamlarda bu elektronik cihazlar tasarlanmış ola…
Bilgi ve iletişim teknolojisindeki büyük gelişmelerin bilgisayar kullanımını ve uygulamalı eğitimi zorunlu kıldığı bir zamanda yaşamaktayız. Bu çalışmada, bilgisayar laboratuvarı sınıflarında rutin yoklama işleminin görüntü işleme tekniklerinden yüz tanıma ile…
The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …
Fins are basic structures which can be easily added to many engineering designs to improve heat transfer from hot surfaces. The addition of a fin to a particular heated surface can significantly increase the cooling at no extra cost. In some cases, standard fi…
Refrigeration and air-conditioning systems consume about 15% of global electricity, and 46% of energy used in household and commercial buildings belongs to heating, ventilation and air-conditioning (HVAC) systems. Vapor-compression technologies dominate the HV…
In the present study, the effects of cutting parameters on surface roughness were investigated in order to determine the optimum machining conditions for the hot work tool steel (155 HB), which is an important part of the mold industry. For this purpose, the m…
The effective control and treatment of chronic diseases requires access to diagnostic tests that are rapid, reliable and very sensitive. Nucleic acid based methods of pathogen detection technologies offer very rapid and accurate results with high sensitivity a…
In this study, the elimination of zero diffraction order and twin image from three dimensional reconstructed images in digital holography and the image enhancement are desired to achieve in a short time by using hybrid methods. In addition, the brightness of t…
Depending on the growing industry and population, energy needs are increasing day by day. In parallel, our external dependency on energy also increases. This issue made it necessary to use of renewable energy sources as much as possible. As an extension of eff…
Several test suites have been developed to test the statistical properties of random numbers generated from pseudotrue random number generators. Some of these are Crypt-X, Diehard, FIPS 140, NIST 800-22 AIS31 test suites. In this study, web based application o…
In the present study, energy and exergy analyses of a solar powered absorption refrigeration system are corried out by terms of the first and second laws of thermodynamics. NH3-H2O fluid couple is used in the system. The analyses are performed with the help of…
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 …
Kablosuz ağlar, veri sinyallerinin havadan iletildiği, kablo kullanmadan uzak mesafeler arasında iletişimi sağlayabilen teknolojilerdir. Kablosuz ağlarda veri, radyo frekansları veya kızılötesi ışınlar vasıtasıyla iletilir. Bu ağlardaki kullanıcılar arasında h…
Görme engellilerin yaşamlarını kolaylaştıran teknolojik gelişmeler her geçen gün artmaktadır. Cisimlerin renklerini algılama onların sesle bildirimde bulunulması ile olabilmektedir. Bu çalışmada optik tabanlı renk sensörü tasarlanarak bu renkleri, renk kelimel…
Günümüzde birçok alanda kullanılan Kablosuz Algılayıcı Ağlar genellikle açık alan uygulamalarında kullanıldıkları için dışarıdan gelen farklı saldırılara karşı korumasız durumda olabilirler. Ağı saldırılara karşı korumak ve verilerin güvenliğini sağlamak, Kabl…
Wireless Sensor Networks have many application fields including both industrial and military usages. They are used for monitoring temperature, distance, light, and motion in laboratories and/or application specific environments. This paper focuses on developin…
