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

Fuzzy delphi method to direct urban renegeration project assessment: Bornova-Kızılay neighborhood

Çupı, Romjana

Resident satisfaction is an important issue in urban regeneration projects (URP). In the western countries, the resident satisfaction from residential environments continues to be an important topic for researchers and the data found well preserved and integrated into real projects. In Turkey, yet, there is little research on residential satisfaction in many urban regeneration projects implemented. In Turkey, up to the present, research carried out about urban analysis and residential satisfaction needed in any urban regeneration project, is little evident in implemented UR projects. Izmir is ...Daha fazlası

Modelling, Analysis and Experimental Verification of Pneumatic Brake System

Güleryüz, İbrahim Can

As the technology develops, the development in vehicle safety becomes an area, which takes the attraction of the researchers who are working in automotive industry. Although systems like air bag system, lane departure warning system (LDWS) and tire pressure monitoring system (TPMS) improve the safety of the vehicle, main studies, in which advanced technology is used mostly focus on the brake system including anti-lock braking system (ABS), traction control system (TCS), electronic stability control (ESC), advanced emergency braking system (AEBS), adaptive cruise control (ACC). Thus, det ...Daha fazlası

Assessment of real estate ownershıp ıssues In urban regeneratıon projects ın turkey

Konbul, Yunus

ASSESSMENT OF REAL ESTATE OWNERSHIP ISSUES IN URBAN REGENERATION PROJECTS IN TURKEY SUMMARY Illegal settlements, urban sprawl and old urban areas can be transformed into livable spaces with urban regeneration projects. Especially because of the earthquake risk and its low quality building stock, Turkey is one of the countries where implementation of those projects is vital. However, real estate ownership problems experienced at the beginning of the urban regeneration projects hinder implementations of the projects. Therefore, identifying and eliminating those problems can help carry out the pr ...Daha fazlası

Computer based X-Ray imaging device design alternative using consumer electronic components

Manalp, Alpman

Medical imaging provides images of structures of the body that is not visible to human eye. It is a basic need that determines the irregularities, abnormalities, parts with different densities, spaces and foreign objects that is not supposed to be in the body. It has major importance for fast and correct diagnose. Imaging is frequently used for periodic scans for early diagnostic and follow up scans of treated patients. No matter how important it is, accessibility of the imaging devices especially digital imaging systems that provides real time images is extremely limited. There are very ...Daha fazlası

Using alcohol as a carrier producing polyanionic cellulose (PAC) polymer from solid textile waste

Karakuş, Hüseyin

Cellulose is the most abundant organic polymer on earth. It is naturally regenerated by forests and cotton plantations with a speed of 10 billion metric tons per year regularly. Not only its natural reproduction makes it ecologically beneficial but also its biological degradability makes cellulose an ‘eco-friendly material’. Applications of cellulose is limited due to its insolubility in water. Contrarily, its water-soluble derivatives, especially cellulose ethers, are found in nearly all the products we are using in our daily life. Although cellulose is the main raw material for producing ce ...Daha fazlası

Investigation of Manufacturing and Characterization of Radar Absorbing Hybrid Structures

Mohamed Yousef Ali Issa

Significant development of radar systems after World War II has led to studying the interaction between electromagnetic waves at radar frequencies and different materials. One perspective of these studies is to ascertain ways of decreasing reflected waves. However, the applications have not been limited only to defense applications but also to different fields where human beings are exposed to electromagnetic waves to avoid potential health effects due to exposure to electromagnetic waves. Since the discovery of radar systems, many studies have focused on electromagnetic radiation and absorbin ...Daha fazlası

Characterization of Clay brick materials produced with red mud and nut shell wastes for building applications

Çam, Ata Sadık

In this study, clay based brick with micro pores was developed for thermal insulation in the building materials. Turkey produces about 70% of the world hazelnut production. The aim of this thesis is to reduce the thermal conductivity coefficient by adding organic waste (hazelnut shell) into clay mixture to form porosity during firing of clay bricks. Moreover, it is to maintain the similar mechanical properties by adding inorganic waste (red mud) into clay mixture. The development of a highly porous bricks with applicable mechanical strength will contribute to save energy in the building ...Daha fazlası

Automatic Detection of Alzheimer’s Disease with Transfer Learning and Image Processing Techniques

Atılay Yeşilada

Alzheimer's disease continues to be a serious public health issue. Alzheimer's disease affects generally old people, and it is a neurological disorder. The most significant sign of Alzheimer's disease is memory loss, which becomes worse over time. Therefore, early identification of Alzheimer's illness can aid in diseased getting the proper care. One of the aims of this thesis is to automate the early detection of Alzheimer's disease and create a self-improving system by utilising previous experiences each time it is detected automatically. In this way, the bad effects of the disease due to the ...Daha fazlası
