A visiual isarithmic mapping tool for online maps

Atalay, Hatice

Within the scope of the thesis study, interpolation methods used for evaluating spatially varying data and for presenting the information obtained from the data via maps were investigated. A method for generating an open source web based interpolation map for the most commonly used interpolation methods is presented. Today, many commercial Geographic Information Systems (GIS) software are used in the production of interpolation maps. However, this situation causes the users to pay a large amount of money or use cracked programs. Although there are open source softwares, which can create interp ...Daha fazlası

The effect of pulsed electromagnetic fields for in vitro wound healing exposure systems

Gümüşay, Mehmet

THE EFFECT OF PULSED ELECTROMAGNETIC FIELDS FOR IN VITRO WOUND HEALING EXPOSURE SYSTEMS SUMMARY Electromagnetic fields have achieved important role as stimulator and therapeutic facility in biology and medicine (Blank & Findl, 2013). The effects of low magnitude, low frequency pulsed electromagnetic fields have been a period of study since past few decades, which was mainly on the treating soft tissue injuries, skin ulcers, nonuniform bone fractures and degenerative nerve healing (Hug & Röösli, 2012b). Chronic wounds are a major healthcare problem for patient morbidity and contribute signi ...Daha fazlası

Aerodynamic design of a novel low pressure compression system for variable-speed micro turbofan Değişken hızlı micro turbofan için yenilikçi düşük basınçlı kompresör sisteminin aerodinamik tasarımı

İlhan, Menal

Özet:İnsansız Hava Araçları (İHA) genellikle pervane tahrikli ve düşük hızlı uygulamalara yöneliktir. Mikro turbojet motorları ise çok daha yüksek yakıt tüketimine bağlı olarak daha kısa menzillere sahiptir. Fiyat ve karmaşıklık sorunları nedeniyle, turbofanlar yerine turbojetlerin kullanımı kısıtlanmaktadır. Bununla başa çıkabilmek için, temel bir mikro turbojet, ek (booster) kompresörü ve düşük basınçlı türbin bileşenleri olmadan tek milli turbofana dönüştürülebilir. Bu normalde eşleştirme sorunlarına neden olur çünkü fan hızını bağımsız olarak ayarlamak için iki mil gerekir. Daha basit bir ...Daha fazlası

Manufacturing and Characterization of Peptide Coated Polylactic Acid Based Composites for Various Medical Applications

Metehan ATAGÜR

Within the scope of this thesis, PLA-based composites have been developed and coated with peptide to increase biocompatibility for temporary implant applications and PLA biocomposite materials have been produced. HA and β-TCP were used as additive materials, and PLLA and PDLA polymers were used as polymer matrix. The main purpose is to obtain the composite with the best mechanical properties and to improve the biocompatibility properties as a result of coating this final material with peptide. In the first stage, 10% HA (PLA-10 HA), 10% β-TCP (PLA-10TCP) and 5% HA + 5% β-TCP (PLA-5TCP-5HA) are ...Daha fazlası

Geometrical Optimization of Dimpled Double-Pipe Heat Exchangers for Nanofluid-based Natural Circulation Loops Operating at Lower Temperatures

Nur Çobanoğlu

Excessive use of global energy sources causes negative environmental impacts and a reduction in the available energy resources. Therefore, energy efficiency is the main scope of engineering studies. Since household refrigeration accounts for a large portion of the energy consumption rate in buildings, several innovative techniques have been developed to improve the energy efficiency of vapor compression refrigeration systems. Suction line heat exchangers are considered one of these techniques and they are used to avoid the presence of liquid at the compressor and to prevent sweating on the suc ...Daha fazlası

Artificial Intelligence Based Resource Allocation in Cell-Free Networks

Mert Demirel

With the rapid development of technology, cellular networks can no longer meet the demands of wireless networks. Communication systems need to be updated to ensure that every user equipment (UE) receives accurate and efficient service. Cell-free (CF) networks offer advantages over cellular networks, such as more flexible resource allocation, higher capacity, better coverage and lower interference. The deployment of multiple access points (APs) and flexible allocation of resources leads to higher network performance and efficiency. In addition, in CF networks, users can communicate with ...Daha fazlası

Detection of dyes in water using smartphone technology for environmental sustaınability

Kocakuşak Özdemir, Gizem

The goal of this thesis is to develop the applicability of an ultra-low cost, field-deployable, plastic fiber based smartphone spectrometer system to study dye adsorption from water. A custom cradle using smartphone’s built-in flash and camera was designed for visible absorbance spectroscopy without any need for external electrical components. We firstly investigated the performance of smartphone spectrometer for methylene blue (MB) absorbance in water with a detection limit of 0.5 ppm, and compared it to that of a commercial spectrometer. We elaborated on the contribution of image formats to ...Daha fazlası

Evaluation of organic waste materials as bio-polymeric admixtures in cement based composite mortars Organik atık malzemelerin biyo-polimerik katkı olarak çimento bağlayıcılı kompozit harçlarda değerlendirilmesi

Kalkan, Şevket Onur

ABSTRACTIn this study, the effect of a new generation bio-polymeric admixture on the physical and mechanical properties of cement mortars is examined in detail. The bio-polymeric admixture is prepared by grinding egg shells, apricot kernel shells, hazelnut kernel shells, walnut kernel shells, and olive seeds in micronized sizes. The evaluation of the bio-polymeric admixtures, which are produced as wastes, among high production materials such as concrete and mortar derivative products, provides an opportunity for better disposal and management of these wastes.ÖZETBu çalışmada, yeni nesil biyopo ...Daha fazlası

Fabrication of hysteresis-free perovskite solar cells by SAM modified electrode SAM modifiyeli ITO elektrot ile histeresis östermeyen perovskit güneş hücresi üretimi

Yalçın, Eyyup

ABSTRACTEnergy has become one of the main problems of humanity after the industrial revolution and the rapid rise in world population. Most energy resources depend on fossil fuels, which causes environmental problems. Solar energy is a clean and sustainable alternative to the increasing world energy demand. In this context, perovskite solar cells (PSCs) are particularly attractive due to ability to achieve very high efficiencies. The power conversion efficiency (PCE) of PSCs has rapidly grown from 3.8 in 2009 to over 25.5 in 2022, which making it fastest advancing solar cell technology to date ...Daha fazlası

Millions of people worldwide suffer from diabetes and diseases caused by diabetes. As a result of the statistical studies carried out by the World Health Organization (WHO), the number of people suffering from diabetes was 108 million in 1980, then it was increased to 422 million in 2014. Diabetes is increasing rapidly, particularly in underdeveloped and developing countries and it was predicted that 1.5 million people died because of it only in 2019 (WHO, 2021).
