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 …

The aim of this study is to forecast installed wind power which is a one of the renewable energy resources in Turkey for the year of 2017 based on artificial neural network method using the normalized last ten-year data. An artificial neural network has been c…

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…

Aim of the study: It is important to be able to plan the production transmission and distribution necessary for uninterrupted electricity and to use the electricity more efficiently and to make demand forecasts. For this reason, it is aimed to estimate the ele…

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…

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…

Increasing in wireless communications systems is caused to increase in the need of the frequency spectrum. CR (Cognitive Radio) measure or sense frequency spectrum activities on spectrum bands whether they are idle or used by licensed users. According to sensi…

Evrimsel algoritma ve parçacık sürü algoritması çok uzun zamandır ayrı ayrı çeşitli karmaşık problemlerin çözümünde yaygın olarak kullanılan sezgisel algoritmalardır. Evrimsel algoritma canlıların çoğalmasını ve hayatta kalmak için en iyilerin seçilmesi tekniğ…

Görüntü bölütleme, görüntü işlemenin önemli aşamalarından biridir ve SRG (Seeded Region Growing – Tohumlu Bölge Genişletme) en bilinen bölge tabanlı bölütleme tekniklerindendir. Bu çalışmada tohum seçimlerinin, tohumlu alan genişletmedeki başarıya etkisi incel…

In this paper, a structural-output is obtained to estimate 3D human pose using 3D human point cloud and monocular images. The Neural Network takes a human image and 3D pose as inputs and gives outputs a score value. Conditional Random Field (CRF) approach is u…

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…

This study presents the investigation of thorium utilization in an ADS with Lead-Bismuth Eutectic (LBE) target. To effectively burn thorium, the ThO2 fuel rods cylindrically prepared, and cladded with SiC, are mixed with 233UO2 at volumetric ratio of 1%. These…

In this article, the influence of the use of three different bricks on the building heat performance is compared for use on wall surfaces as a building construction element. At the beginning of the analysis, the thermal analysis of the building was carried out…

In this paper, a thermal insulation analysis was carried out for a building using paper waste reinforced clay brick as building material. Firstly, the analysis was made using two different normal wall bricks as building material for the sample building. Later,…

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 …
