Beginning from the 20th. Century, Architectural designs and plans are became more complex because of the increasing of functional needs. This appeared an orientation problem for users of the big complex buildings like hospitals, airport, shopping mall, etc. …
Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turb…
High rise buildings are a type of structure that depends on many things such as rapid urbanization, population growth, high land prices, transportation problems, prestige concerns, development in construction and material technology. In these structures that…
Current study is related with numerical simulation of a centrifugal pump impeller with the specific speed of nq=13. By the help of computational fluid dynamics (CFD) at different operating points, pump performance rsults (Head-Discharge graph) are obtained. Si…
Today, human beings encounter countless visual narratives every day and sometimes they can construct reality through these narratives. Creation of perfect visual images for perfect visual appeal also brings along with the sense of “ideal beauty". Transmisions …
From the time that humans first started to live in a settled way, the effect of public places (as the common space for the people from every section of the community) on communications with their surroundings, and the need to meet the main requirements, have…
Çağımızda hızla gelişen teknoloji ve bilgi sistemlerinin birbiri ile entegrasyonu, işletmelere rekabet ortamında varlıklarını sürdürebilme ve gelişme imkanı sağlamaktadır. Bilgi teknoloji sistemlerinden yararlanma yöntemlerinden biri olan Kurumsal Kaynak Pla…
Complex permittivity of soil is connection with volumetric water content robustly. Especially, Dielectric constant rapidly varies with volumetric water content because of the robust connection between volumetric water content and dielectric constant, if volu…
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…
Güç sisteminde akım ve gerilimin dalga formunun sinüsoidal formda olması gerekir. Fakat bu her zaman mümkün olmaz. Non-sinüsoidal gerilim veya elemanlar güç sisteminde harmoniklerin oluşmasına sebeb olur. Harmonikler güç sisteminde, ek ısıl kayıplara, rezona…
Bu çalışmanın amacı, geleneksel Türk sporlarından biri olan güreş sporuna yönelik bireylerin tutumlarını ölçmek amacıyla Guttman tipinde bir tutum ölçeği geliştirilmesidir. Guttman ölçeğinde, Thurstone ve Likert ölçekleri gibi diğer tutum ölçeklerinde temel …
Bu çalışmada, robotik uygulamalarda yaygın bir şekilde kullanılan kapasitif rotary enkoder anlatılacaktır. Kapasitif rotary enkoderler hem açısal pozisyon hem de açısal hız ölçmede kullanılmaktadır. Enkoder temel olarak 3 ana parçadan oluşmaktadır: 1. komple i…
In this paper, signal recognition system is proposed for classification of soil types and buried object by using feature extraction and artificial neural networks. Using GprMax simulation program, 300 GPR A scan signals were obtained for different ground plane…
Point Cloud is widely used in reverse engineering services and in many architectural works. Because the Point Clouds contain elements that reach the extreme numbers; they have increased the need to develop new methods in their management, presentation and proc…
Günümüzde, endüstri ve ticaret alanında, ağır yüklerin çeşitli yöntemlerle kaldırılıp bir yerden başka bir yere taşınması gerekir. Bu işlerin üstesinden gelme amacıyla mobil vinçler yaygın kullanıma sahiptir. Mobil vinçlerin güvenli ve uzun ömürlü çalışmasını …
[Cp2V{S2CN(CH2)4O}]+ and [(η5-C5H4Me)2V{S2CN(CH2)4O}]+ complexes are optimized B3LYP/GEN level (GEN keyword is mean that LANL2DZ basis set for metal atom and 6-31G(d) basis set for S, O, N, C and H atoms) in gas phase. The aim in this study, the molecular st…
Introduction. Environmental pollution is a global ecological problem for today. Georgia is no exception. Among the many other contaminants, the environment here poses a serious threat to military wastes left by the former soviet Army, including toxic substan…
Bu çalışmada, ağırlıkça %0.1, %0.3 ve %0.5 oranında grafen nanotabaka (GNT) takviyeli alüminyum (Al) matrisli kompozitler toz metalurjisi metoduyla üretilmiştir. Üretilen kompozitlerin deneysel yoğunluğu, çekme dayanımı, aşınma oranısırasıyla; Arşimet yoğunl…
ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…
