Hızla gelişen teknoloji ve beraberinde getirdiği yeni ihtiyaçların artışı toplumsal bir tüketim kültürünün doğmasına sebep olmuştur. Bu tüketim kültürü, doğal kaynakların büyük bir hızla azalmasında etkin rol oynamaktadır. Doğal kaynakların korunması ve çevr…

Bu çalışmada, DIN 1.2738 çeliği CVD kaplı karbür kesici takımlarla kuru kesme şartlarında tornalama deneylerine tabi tutulmuştur. Kesme parametreleri; üç farklı kesme hızı (150, 200, 250 m/dak), üç farklı ilerleme hızı (0,1, 0,15, 0,20 mm/dev) ve sabit kesme…

Hardox çelikler mükemmel aşınma direncine sahip, ultra yüksek mukavemetli, kayma ve darbe aşınmasına karşı dayanıklı martensitik çeliklerdir. Madencilik ve inşaat mühendisliği endüstrisinde ağır makineler ana uygulama alanıdır. Bu çalışmada, Hardox 400 çeliğ…

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…

Infill walls in reinforced concrete buildings produce a strong effect on the strength and deformation capacity of the buildings. In practice, a partial or full absence of infill walls at the first stories may become one of the reasons for vertical irregularity…

AFAD Logistics warehouses, stocked by the Red Crescent in Turkey in diameter will be needed after a possible earthquake in Istanbul on the amount of temporary sheltering units were established considering the amount of material inside the tent and the tent. It…

Urban areas have less vegetation than natural environment that surround it. Differences between these types of areas affect climate, energy use, and habitat in cities. In urban areas, dark surfaces and reduced vegetation warm affect the air over urban areas, l…

Today, the universal development tool of the globalization in the world is ICT. Therefore, the capacity of using advanced tools of ICT in developed countries is increasing rapidly. Intelligent technological tools have become a part of our lives. Intelligent sy…

In this study, 0-12wt.% of Si3N4 or 0-30wt.% of SiC was added to the aluminum matrix by powder metallurgy method. Hence, the effect of reinforcement elements’s (SiC or Si3N4) amount on the mechanical properties was examined. Micro structures and crystal struct…

TiO2 films have been deposited by sol gel spin coating technique onto glass and p-Si substrates. TiO2 films were prepared using two different sols. The physical properties of the TiO2 films were examined based on two different parameters. In the first study,…

Recently, works on the development of equipment in the field of power electronics has been increasing day by day. Inverter design is one of the outstanding issues in the field of power electronics. One of the most important of these studies has been the multi-…

Open-finance interfaces make market data and trading services programmable, but an API response is not an executable signal. Economic information depends on data receipt, inference completion, and feasible order arrival. We propose an execution certificate: a …

Adaptive research systems can generate, discard, revise, and monitor trading rules faster than their selection history can be audited. We ask when such a system may promote a frozen rule to governed forward evaluation. The proposed protocol assigns each candid…

In the United States, banking desert status is classified annually from that same year’s branch data, producing a contemporaneous snapshot of current access rather than a forecast of which communities are likely to change status next. This study tests whether …

Afet risklerinin azaltılmasında, fiziksel zarar görebilirlik düzeylerinin mekânsal olarak belirlenmesi ve görselleştirilmesi, kentsel dayanıklılığın artırılması açısından kritik bir öneme sahiptir. Bu çalışma, Amasya kent merkezinde afet kaynaklı fiziksel kırı…

In the present study, a model drug, with its low permeable and low aqueous soluble properties, was selected to produce microparticles using an anti-solvent precipitation technique with two different drugs: polymer (0.5, 1.0, w/v %) ratios. The characterization…

Son yıllarda insan yaşamını tehdit eden doğal afetlerden biri de heyelanlardır. Ülkemizde özellikle karadeniz bölgesinin gerek eğim gerekse yıllık toplam yağış miktarları, heyelanların nedenleri arasında gösterilmektedir. Bu çalışma kapsamında doğu karadeniz b…

In this paper, the Ku-band rectangular microstrip patch antenna (RMPA) is intended to operate in the dual-band for satellite communication (SATCOM). The antenna which is obtained for dual-band by utilizing a U-slot and vertical slits on RMPA is fed with a micr…

In this study, multi-walled carbon nanotubes (MWCNT) in different weight ratios effect on the mechanical properties of modified epoxy based adhesive under an axial load was investigated. 0.25, 0.50, 0.75 and 1 % by weight ratio the MWCNT added epoxy adhesive…

Fotovoltaik (FV) sistemler birkaç W’dan, MW’a kadar ölçeklendirilebilmesi gibi özelliklerinden dolayı en çok yaygınlaşan yenilenebilir enerji kaynağı türüdür. Bu enerji kaynağından en yüksek oranda yararlanılabilmesi maksimum güç noktasını izleyen (MPPT) dönüş…
