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.

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
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
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
Humankind have an interest to obtain marine meteorological data for decades, therefore, constant and mobile meteorological stations have been used for the correct measurements. These meteorological data include wind speed and direction, sea surface and air temperature and cloud cover. Ship-mounted anemometers have been used for meteorological observations, obtaining the wind speed data and climate change analysis. Wind data are especially gathered and reported by Voluntary Observing Ships (VOS). World Meteorological Organization (WMO) created the VOS program to ensure reporting of the wind dat ...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
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
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
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
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
