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
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
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
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
Today, thermoplastic polyurethane materials are widely used in many different
applications. There are many types of thermoplastic polyurethanes which offers
different mechanical and chemical properties according to application area. In
addition to the existing properties, thermoplastic polyurethane materials mixed with
various additives to obtain specific, targeted thermoplastic polyurethane materials in
order to impart different properties to the material for application.
In this study, materials of the sealing elements are approached which is one of the
most important parts of the hyd ...Daha fazlası
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
The progress of electronic information technology brings along some problems caused by electromagnetic (EM) waves. For this reason, electromagnetic absorber materials have drawn attention recently for application areas such as electronic, defense stealth technology, and satellite communication systems.

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).
The recent increase in life expectancy and changing living conditions have led to a
rise in developments regarding implants, particularly in orthopedic implants. It is
important to note that this statement is based on objective evidence and not
subjective evaluations. Despite these advances, issues with metallic implants such as
Ti, Ti alloy, Co-Cr alloy, and stainless steel (AISI 316L), which are currently
preferred, persist. There are several limitations to implant materials, including
corrosion due to the physiological environment, bacterial infection, and biofilm
formation. Although ...Daha fazlası

Radar, uçakların tespiti ve takibi için en yaygın tekniktir. Radar, havacılık trafik yönetiminde vazgeçilmez bir araç olmasına rağmen, uçağın hedefini saldırıp fark edilmeden kaçmasını gerektiren saldırgan askeri operasyonlarda sorun oluşturur. Radar, elektromanyetik dalgaların atmosfere yayılmasını içerir; daha sonra uçaktan yansıyarak bir alıcı antene geri döner. Radar Emici Malzemeler (RAM), uçağın elektromanyetik dalga enerjisini emerek yansıyan sinyalin yoğunluğunu en aza indirmesi prensibiyle çalışır. Gizlilik ve görünmezlik gibi son derece önemli olan gizlilik teknolojisini sağlayan rad ...Daha fazlası
