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

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

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

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).

Investigation of changes in the formation and types of non-metallic inclusions in the steel production process Çelik üretim sürecinde oluşan metal olmayan kalıntıların oluşumu ve değişimlerinin incelenmesi

Bakar, İbrahim

ABSTRACTIt is not possible to produce steel without inclusions as the process for steel production requires. Based on this fact, the researches on clean steel are concentrated on the reduction of inclusions and transformation of inclusions into harmless state by modification. The definition of steel cleanness is related to final product application. Non-metallic inclusion, in the liquid steel, causing many problems and production lost in steel production process and final application. Aluminum killed steels mostly contain Al2O3 and MnS inclusions. Al2O3 inclusions are formed during de-oxidatio ...Daha fazlası
