Thermal insulation term is the most important measure that provides the thermal
comfort which human being has been looking for as a natural habit from the first
residential lifestyle begins.
The inventions in this topic, especially has been arisen in last centuries and
specifically in the last century it has been carried forward and both aesthetic and
performance based products have been researched to be discovered.
In the light of researches each in academic and practical fields, the hope of this
demand to be provided is increased via innovative insulation materials.
Accordingly, to c ...Daha fazlası
In recent years, laminated composites are fairly utilized in marine, automotive, aerospace, military and other engineering applications because of their high specific modulus (ratio between the young modulus and the density) and high specific strength (ratio between strength and density). In addition to these features, fiber reinforced composites have inherent tailorability such as fiber orientation and stacking sequence and provide great possibilities to designers against isotropic materials. Determination of the fundamental frequency performance of laminated composite plate is crucial for th ...Daha fazlası
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
The use of nonlinear analysis methods is widely preferred to determine the realistic
behavior of the structures through the computer technologies developed in recent
years. However, the stability problems that significantly affect the structure behavior
are often neglected in nonlinear analysis and in computer programs that are frequently
used to the realization of these analyses. Lateral torsional buckling behavior, which is
one of the stability problems, is considered to be neglected in many studies using
nonlinear analysis methods in the literature. As a result, the realistic behavior ...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
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
Garment and textile production industry is one of the main sectors of our country.
This sector is a major driving force in our developing economy. According to 2014
data, Turkey is the third country on textile export among the European countries.
Besides, Turkey is the world's sixth largest garment exporter. With such a huge
production power, in Turkey’s textile sector, waste and/or residual textile materials
are composed depends on the large scale production, as in most of the other
production sectors. Such waste materials in textile industry are the left materials from
production stag ...Daha fazlası
The compounds bonded with functional groups in textile materials carry the economical support material property. The complex and/or organic compounds with the desired properties can be immobilized into the textile materials by using the reactivity of hydroxyl groups of cellulose and the NH2 groups in wool. Most of commercially purchased silver salts show a rapid release of silver in water because of their ionic structure. For this reason, they exhibit high antibacterial activity but the short-term. N-heterocyclic carbene (NHC) complexes have the long-term antibacterial effects by releasing the ...Daha fazlası
In this thesis the development of Afghanistan’s banking system and the role of domestic
banks in the economy of Afghanistan has been researched. Moreover, the effects of
banks and the banking system to business sector, financial sector and to private sector in
the country have been handled. Most of banking system was dead over 25 years of war
due to abnormal condition in the country. After the new regime, the development of
banking systems takes a new look in 10 years across the global transaction. Thus, get the
positive feedback in these years. This change also played a big role in Afgh ...Daha fazlası
The main purpose of my thesis is to develop a Swarm Robotics Platform which will
use Cellular Automata Glider model and generate itself with “Game of Life” rules.
The method was experimentally tested with autonomous mobile robots and real-time
PC based simulation software, in all cases very good paths were obtained with
negligible processing effort, and low cost production. Presented results indicate that
the Cellular Automata approach is a very promising method for real time path planning
and Glider like robotic swarms can be used for self-replicating and moving swarm
robots.

In environment of globalization and intense competition, businesses make
their long-term plans in order to sustain their existence. This planning ensures
employees to understand the points of organization’s mission, its goal, the place
where it wants to reach and how it will get there, and it is thought that organizational
communication plays an important role in this respect.
In this context, the main purpose of the study is to a research about discussion
of organizational communication and strategic planning process. In the research
where interview was preferred as data gathering tech ...Daha fazlası
3D (Dimensional) microtissues are commonly used in regenerative medicine, medicine design, toxicology studies and advance cancer research. Microtissues which are constructed by this technique mimic natural in vivo condition and it stands for shifting form between in vitro studies and in vivo research. Scaffold-free microtissues produce own extracellular matrix and cells proliferate faster. However microtissue is used in vitro experiments, they mimic in vivo condition by producing own matrix.
Recently, RGD peptides which are commonly used biomaterials consist of GRGDS sequences and it has acti ...Daha fazlası
