Urban regeneration projects in squatter settlements, the case of Izmir, Bayraklı urban regeneration project Gecekondu alanlarında kentsel dönüşüm projeleri, İzmir örneği, Bayraklı kentsel dönüşüm projesi

MERVE ÖZKAN

ABSTRACTUrban regeneration projects studied extensively in the world and Europe is a new subject in Turkey. When we look at the examples in the world, their main focus has always been human-oriented. These types of projects should take into account the city's authentic memory and texture, depending primarily on the physical, social, cultural and economic structure. The theme of the project should be determined considering local, social, cultural and physical principles. Ecological values should be decisive in the project's outset, course and outcome. Regeneration projects can actually be consi ...Daha fazlası

Biomechanics of acetabular fractures with low energy trauma via finite element modeling and analysis Düşük enerji travmalı acetabular kırıklarının sonlu elemanlar modeli ve analizi

SAMET ÇIKLAÇANDIR

The skeletal system undertakes many tasks such as the movement of the body, mineral storage, and protection of soft tissues. Damage to this structure affects human life negatively. Fractures that occur in the human body is damage to mainly to the bone structure and associated surrounding tissues. Therefore, it is necessary to understand how the fractures are formed and the fracture mechanism. Furthermore, the mechanism of fracture is complicated and worthy of investigation. However, the examination of the bone is difficult because it is a structure covered with tissues like veins and muscles. ...Daha fazlası

Tattoo dye removal using cold athmospheric plasma (CAP) Soğuk atmosferik plazma (SAP) kullanarak dövme boyası silme

ELİF ÇUKUR

ABSTRACTTattoo has been used as a method of self-expression of mankind since ancient times. The tattoo removal process with primitive methods is based on the process of peeling the skin layer on which the tattoo is placed. Besides being used today, laser is preferred by more people. The tattoo removal with laser is based on disintegration into smaller pieces by breaking the target tattoo pigment by absorbing the transmitted beam. It is then transferred to the nearest lymph node or disintegrated by the macrophages by means of blood or lymph circulation. The most common difficulty with laser tat ...Daha fazlası

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

Urban regeneration contexts in historical cıty centers: Izmir, Kemeraltı case Tarihi kent merkezlerinde kentsel dönüşüm boyutları: Kemeraltı örneği

Yakıcı, Nilay

ABSTRACTCities that have a history as a capital or an important trade center, has its own complex structure. If the historical city center was functionalized as a commercial district, it has been experienced social, cultural, environmental and economical subjects throughout centuries. This situation creates strong impacts as newly created contexts likewise political, public and architectural. These contexts generally not thought together, but they should be analyzed and investigated together for a sustainable future for the historical city centers. As a historical city center, Kemeralti-Izmir ...Daha fazlası

Investigation of the cooling system efficiency in aluminum low pressure die casting Alüminyum alçak basınçlı dökümde kullanılan soğutma sisteminin veriminin araştırılması

Yavuz, Hakan

ABSTRACTIn this thesis, the flow rate of air coolers used in low pressure casting method is examined. Low pressure die casting (LPDC) method is used for many types of products. Light alloy wheels, motor housings and pistons are examples of these products. Air-cooling is used to provide directional solidification to avoid casting defects on the casting part. In this study, the flow rate of air-cooling is calculated by using computational fluid dynamics (CFD) methods. After the numerical calculations were confirmed by experimental methods, the affect of the variables on the cooling system flow r ...Daha fazlası

Growth of zno-ch nanostructures on ito/glass substrates through electrochemical anodization for biosensor applications Biyosensör uygulamaları için elektrokimyasal anotlama yöntemiyle İto/Cam yüzey üzerinde Zno-Kitosan nanoyapıların büyütülmesi

Uzunbayır, Berkant

ABSTRACTIn recent years, the utilization of nanotechnology rapidly developed for the wide range of sciences. Nanomaterials shows unique properties and ZnO nanostructures are the most suitable structures for biosensor applications due to their high surface area and high electrochemical activity. In this project first, we have coated zinc film on to Glass/ITO surface by electrochemical deposition method. Then we have transformed the obtained zinc film to nanostructured ZnO by electrochemical anodization method. At the end, we have tried to modify the ZnO nanostructured surface with chitosan for ...Daha fazlası

Estimation of annual energy production of coupled vertical-axis wind turbines in a semi-complex terrain Eşli çalışan düşey eksenli rüzgar türbinlerinin yarı karmaşık bir sahadaki yıllık enerji üretiminin değerlendirilmesi

Başer, Ferhat Cem Ferhat Cem

ABSTRACTRecent research shows that the vertical-axis wind turbines (VAWTs) can provide up to 6 - 9 times more power generation in the same footprint area when they are sited in proper configurations in contrast to horizontal-axis wind turbines (HAWT). In order to site wind turbines in a field, it is necessary to do a wind resource assessment (WRA). This assessment provide important inputs for the placement, sizing and design detailing of the wind farm. In addition to the correct determination of the site, it is also critical to place the wind turbines in the most efficient way. When the necess ...Daha fazlası

Development of novel donor and acceptor sam molecules for photovoltaic applications Fotovoltaik uygulamalar için yeni nesil donör ve akseptör kendiliğinden organize tek katman moleküllerin geliştirilmesi

Arkan, Emre

ABSTRACTSurface modification of indium tin oxide (ITO) is a crucial factor to alter the energy level barrier between ITO and perovskite that has direct influence on the charge extraction and recombination at interface. This henomenon has further direct effect on device parameters such as open circuit voltage (VOC), fill factor (FF), and short circuit current density (JSC). This study was base on the synthesis of six novel SAM molecules to be used in fabrication of p-i-n type perovskite solar cells. Since proposed SAMs are of push-pull type molecular nature, contiguous thiophene rings were used ...Daha fazlası
