Dijitalleşen dünyada teknolojinin insanlığa sunduğu sınırsız iletişim olanakları beraberinde büyük değişimleri de getirmektedir. Dünyaya ilişkin her türlü bilgi ve gelişme kısa sürede paylaşılmakta ve ilgi görmektedir. Bunun yanında seyahat maliyetlerindeki dü…

A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…

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…

In this study, the impregnation of Lareks wood with borax and nanotechnological varnish at various vacuum / diffusion times according to ASTM 1413-76 standards and the changes on technological properties were investigated. Pressure resistance properties were d…

Universities play a key role in the cultural and economic development of countries. It also provides necessary and useful information to the community. Industry university collaborations are essential for the emergence and diffusion of innovations. For these r…

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…

Geriye dönük adım akışı, ısı depolama kaplarının iç ve dış akışında veya güç dönüştürme sistemlerinin toplayıcıları gibi birçok cihazda önemli olup akışın karmaşık yapısı nedeniyle önemli geometrik modellerden biri olarak göze çarpmaktadır. Bu çalışmada, dikey…

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…

The paper is deals with Glass Structures, used as a component of nonlinear shaping architectural forms in historical urban environment. These forms are treated as a city-event per analogies to Bernard Tschumi's theory of „event cities”. In this theory, the ess…

This study includes the design of quadratic cascade DC/DC boost converter with PI controller. Two or more cascade boost converters have been used to increase system efficiency. Advantages of the proposed converter compared to the conventional boost converter a…

Dünyadaki enerji tüketiminin %40’ının binalar tarafından gerçekleştiriliyor olması ve bu oranın büyük bir bölümünün ise kullanıcılara termal konfor sağlamak amacıyla ısıtma soğutma ve havalandırma amacıyla kullanıyor olması nedeniyle yapıların enerji etkinliği…

Since the human being has existed, it has benefited from nature in the direction of itsneeds.Needs later turned into art, and as a result, we had handicrafts. Handicrafts are the mostvivid and meaningful documents of a cultural personality of a nation. After t…

Uyku bozuklukları toplumda yaygın olarak görülen bir halk sağlığı sorunudur. Uyku; zaman, ışık, beslenme gibi birçok çevresel faktörden etkilenen 24 saatte bir tekrar eden sirkadiyen ritmin önemli bir parçasıdır. Uyku bozuklukları; İnsomnia [kronik uykusuzluk]…
