OPTIMUM DESIGN OF ANTI-BUCKLING BEHAVIOUR OF THE LAMINATED COMPOSITES BY DIFFERENTIAL EVOLUTION AND SIMULATED ANNEALING ALGORITHMS

Akçair, Mehmet

Laminate composites can be used quite naturally in automotive, marine, aviation and other engineering branches. Determination of buckling load capacity under in-plane composite loads of composite plates is very important for the design of composite structures. In this thesis, Differential Evolution (DE) and Simulated Annealing (SA) are utilized for optimal stacking sequence of a laminated composite plate, which is simply supported on four edges and is subjected to biaxial in-plane compressive loads. The optimization problem parameters are defined as (i) Objective function: critical buck ...Daha fazlası

Design of wireless controlled robotic hand

Kızıltaş, Faruk Sanberk

Thanks to the rapid technological development, robot usage in human life increases day by day. Various kinds of robots that are designed for different tasks aim to increase the quality of human life by replacing or reducing required human power in related areas. Being able to interact robots from a distance by using wireless communication not only provide mobility and ease of use to the user but also promote the usage of robots into various areas. Considering these, this study aims to design a lower degrees of freedom robotic hand with respect to the natural anatomy of the hand and control i ...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

Enhancement of the electrical properties of graphene for electronic devices

Ersu, Gülsüm

Graphene, a one-atom-thick two-dimensional material, has drawn great interest for many electronic and optoelectronic applications due to its extraordinary properties. The properties of the graphene can be modified with different chemical methods and introduced new properties, which widens its potential for applications. The non-covalent modification of graphene is one of the basic techniques for modifying the electrical properties of graphene without disrupting the structure. In this thesis, the high-quality graphene has been synthesized and electrical properties of graphene have been tuned b ...Daha fazlası

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

Effects of beta -tricalcium phosphate concentration on osteogenic differentiation of human mesenchymal stem cells in chitosan based composite scaffolds

Demirci, Emine Afra

Today, tissue transplant applications are widely used for repair of damaged hard tissue. Despite the gold standard of autografts, interest in synthetic bone grafts produced by tissue engineering techniques is increasing day by day, due to limiting factors such as damage to the tissue site and limited graft availability in allografts, and the risk of developing an immune system response in allografts.Many bioceramic materials, including β-tricalcium phosphate (β-TCP), hydroxyapatite (HA) and calcium sulfate, are widely used in bone tissue engineering. β-TCP has been the most preferred biocerami ...Daha fazlası

Design and development of a collimator mechanism that will be utilized in radiation therapy

Yazıcı, Mustafa Volkan

This thesis focuses on a Multileaf Collimator design that can shape the beam contour to fit the shape of target geometry and its design improvements. Main purpose of this design is lowering the number of leaves on the multileaf collimator and making the system easier to be controlled. As the Collimator devices undertake the most important point of the beam shaping procedure, ease of control and precision of collimator devices are the major points of operation. As the radiation therapy is one of the most complex and vital medical operations, this thesis started with the deep literature survey ...Daha fazlası

Smart business accounting software as an android mobile application using artificial imtelligence

Okyay, Muhammet Serhat

In this study, the necessary data obtained from the databases (such as MSSQL, Mysql, Postgre SQL, etc.) of the softwares like ETA and NETSİS that are used for preaccountancy of the local and global companies were read, some of the data were written to the databases, and this data was used by the end user by using mobile phones or tablets carrying Android operating systems and working with Internet and cloud technology. In addition, new data sets that are collected on a cloud system from the accounting data while the company is on was studied by genetic algorithms which are one of the artificia ...Daha fazlası

Custom designed optical tweezer for trapping yeast cells

Çobanoğlu, Nur

The goal of this study is developing custom designed optical tweezer which uses two He-Ne lasers (λ=632.8 nm) parallel to each other to trap yeast cells. The characteristic specs of this optical tweezer determined by Brownian Motion of polystyrene beads in water. Stiffness and trapping forces of optical tweezer calculated for laser 1, laser 2 and when both lasers used simultaneously. Laser 2 can trap and move particle to laser 1 and multiple particles can be trapped by the laser 1. After determination of specs of optical tweezer, yeast cells in yogurt culture medium were trapped by lase ...Daha fazlası

Effects of ınternal marketıng on servıce qualıty ın accommodatıon busıness : a research for the fıve stars hotels ın Izmir

Sönmez, Gülser

The concept of internal marketing is discussed in the literature more than ten years. Despite the rapid increase in publications related to the subject, many companies are benefiting from this concept in practice. Many businesses still do not know exactly what the concept is and how to apply it. The most basic reason for this is that the research on the concept is rather limited and inadequate. This makes practical research more essensial among with descriptive research for the concept. This study examines the effect of internal marketing practices on the quality of service hotels.
