Forest functions traditionally included wood production, protection and forest recreation. The twofold role of forests as both sources and sinks of greenhouse gases makes their influence on the climate extremely significant. This fact has led to climate chan…

Because of the wide, scattered and large part of the forest areas being located far away from the settlement areas, transportation can only be realized through forest roads and the importance of transportation of forest roads has been emphasized. The grading…

Forest workers generally work under severe conditions. Wood work; far from social spaces, weather conditions and rugged terrain. There is also no room for errors that are connected to a plan. Accident risk is high in forest workers. Accident risk must be hig…

Teknoloji günümüzde her alanda kullanılmaktadır. İnsansız Hava Araçlarının da çeşitli sektörlerde (İHA) kullanımı gün geçtikçe artmaktadır. İlk zamanlarda askeri amaçlar için kullanılan İHA teknolojisi, günümüzde jeodezi, tarım, meteroloji, iletişim, acil du…

Hyperspectral images offer a good separability among land cover classes, owing to their advantages to provide spectral bands with narrow wavelength intervals. It is also possible to further increase classification accuracy of hyperspectral images by integrat…

Günümüzde dünya nüfusunun hızla artması ve orman kaynaklarının azalması sonucu doğal ahşap malzeme kullanımı oldukça azalmıştır. Ayrıca masif malzeme kullanımını ekonomik nedenlerde sınırlandırmaktadır. Doğal ahşap malzemelerin yerine çeşitli odun kökenli le…

Bu çalışmanın amacı, dünyada ilk 10’a giren ve hisse değerlerine ulaşılabilen düzenli hat taşımacılığı yapan 8 şirketin hisse değerlerinde etkin piyasa hipotezinin geçerli olup olmadığının tespit edilmesidir. Bu doğrultuda, zayıf formda etkin piyasa hipotezi…

Araştırmada; bazı ahşap türlerin boyut stabilite değerlerini belirlemek ve iç/dış mekan koşullarında kullanım düzeyinin tespiti hedeflenmiştir. Boyut stabil testleri 6, 24, 48, 72, 96 (saat) periyotlarında gerçekleştirilmiştir. Çeşitli emprenye maddeleri AST…

Yaşamış olduğumuz yüzyılda çeşitli organik malzemelerin kullanımıyla insan/çevre sağlığı büyük önem kazanmıştır. Bu nedenlerle çok çeşitli materyallerden (bitkisel, hayvansal, atıksal vb) elde edilen organik koruyucular üretilmesi devam edegelmektedir. Araştır…

In the analysis of the flood routing problem, it is necessary to determine the change of the flood wave moving through the channel according to time and location, and in this context, nonlinear 3-parameter Muskingum model (NL-MUSK) is widely used. The parame…

In this talk, we investigate a model of the oxygen-phytoplankton-zooplankton dynamics to understand the underlying properties of the effect of environmental stochasticity both on oxygen production rate and phytoplankton growth rate. We address this issue the…

In the last century, there has been an ever-increasing demand for novel materials namely known as composites. Biological fibers are reinforcement materials of composite structures owing to their economic and ecological advantages. Among these fibers, plant f…

Interest, which is known as the rent of money, is one of the most important processes of business life. Throughout history, interest has maintained its importance. People have made money transactions with interest since the known date. It has even been instr…

Climate change and environmental concerns led the investors to search for environmentally sustainable and friendly investments. Green bonds market has emerged as a result of this need. This study aims to analyze this market focusing on market efficiency. Marke…

This study was carried out to determine pre-operative anxiety levels of day surgery patients. This descriptive study was conducted between june 2016 and october 2017 in the general surgery clinic of Yalova State hospital. The study population consisted of adul…

Micro electro mechanical systems (MEMS) technology enables us to create any pattern with any dimension. There are many surface patterning techniques which help us transfer the desired pattern from mask to the wafer surface. Predefined patterns on the wafer sur…

In order to increase the performance/cost ratio of solar cells, new approaches reducing optical and electrical losses are necessary during the absorption of the light and collection of charge carriers. In this work we focused on various textures on Si surface …

In this study, dependency structure of order statistics which are widely used in statistical hypothesis, prediction problems, statistical process controls, reliability, risk management and many applied areas have been investigated with copulas. Dependency rela…

The high consumption of surfactants throughout the world (more than 15 million tons/year), together with their toxicity and negative effect on the self-purification capability of surface waters, make these synthetic organic compounds one of the main environmen…

Masif odun ve odun esaslı kompozit malzemeler, elde edildikleri ağaç türüne göre farklı sertlik değerine sahiptir. Bu özellik ahşabın kullanım alanında önemli bir faktördür. Bu çalışmada, doğu çınarı (Platanus orientalis L.), dut (Morus Sp.), kızılçam (Pinus…
