Simulation and design of a glider swarm robotics platform

Gül, Kasım

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.

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

The effect of pulsed electromagnetic fields for in vitro wound healing exposure systems

Gümüşay, Mehmet

THE EFFECT OF PULSED ELECTROMAGNETIC FIELDS FOR IN VITRO WOUND HEALING EXPOSURE SYSTEMS SUMMARY Electromagnetic fields have achieved important role as stimulator and therapeutic facility in biology and medicine (Blank & Findl, 2013). The effects of low magnitude, low frequency pulsed electromagnetic fields have been a period of study since past few decades, which was mainly on the treating soft tissue injuries, skin ulcers, nonuniform bone fractures and degenerative nerve healing (Hug & Röösli, 2012b). Chronic wounds are a major healthcare problem for patient morbidity and contribute signi ...Daha fazlası

Aerodynamic design of a novel low pressure compression system for variable-speed micro turbofan Değişken hızlı micro turbofan için yenilikçi düşük basınçlı kompresör sisteminin aerodinamik tasarımı

İlhan, Menal

Özet:İnsansız Hava Araçları (İHA) genellikle pervane tahrikli ve düşük hızlı uygulamalara yöneliktir. Mikro turbojet motorları ise çok daha yüksek yakıt tüketimine bağlı olarak daha kısa menzillere sahiptir. Fiyat ve karmaşıklık sorunları nedeniyle, turbofanlar yerine turbojetlerin kullanımı kısıtlanmaktadır. Bununla başa çıkabilmek için, temel bir mikro turbojet, ek (booster) kompresörü ve düşük basınçlı türbin bileşenleri olmadan tek milli turbofana dönüştürülebilir. Bu normalde eşleştirme sorunlarına neden olur çünkü fan hızını bağımsız olarak ayarlamak için iki mil gerekir. Daha basit bir ...Daha fazlası

Surgical Treatment Of Symptomatic Coiling Or Kinking Internal Carotid Artery

GALİP AKHAN | ALİ GÜRBÜZ | LEVENT YILIK

Coiling of the artery is a rare morphologic entity most frequently described in the internal carotid artery. Herein we present two cases with symptomatic kinked internal carotid artery: one suffering from paresthesia of the right arm and speech disturbances and the other suffering from weakness of the left half of the body and speech disturbances. Both patients were treated surgically. None of the patients experienced any peri- or postoperative complications.

Manufacturing and Characterization of Peptide Coated Polylactic Acid Based Composites for Various Medical Applications

Metehan ATAGÜR

Within the scope of this thesis, PLA-based composites have been developed and coated with peptide to increase biocompatibility for temporary implant applications and PLA biocomposite materials have been produced. HA and β-TCP were used as additive materials, and PLLA and PDLA polymers were used as polymer matrix. The main purpose is to obtain the composite with the best mechanical properties and to improve the biocompatibility properties as a result of coating this final material with peptide. In the first stage, 10% HA (PLA-10 HA), 10% β-TCP (PLA-10TCP) and 5% HA + 5% β-TCP (PLA-5TCP-5HA) are ...Daha fazlası

Investigation of the Effect of Electrode Material on Antibacterial Activity in Plasma Treatment with Dielectric Barrier Discharge

Merve Gül

Plasma is an ionized gas generated under an electric field that contains photons, free electrons, ions, free radicals, and reactive oxygen/nitrogen species (RONS). Cold atmospheric plasma (CAP) is generated in the cold form under a high electric field at atmospheric pressure. CAP is generated using two methods, Dielectric Barrier Discharge (DBD) and plasma jet. In the DBD method, the electrode configuration, shape, material, and substance from which the dielectric barrier is made are important. Beyond the electrode design and geometry, the barrier and electrode materials can also impact the re ...Daha fazlası

Geometrical Optimization of Dimpled Double-Pipe Heat Exchangers for Nanofluid-based Natural Circulation Loops Operating at Lower Temperatures

Nur Çobanoğlu

Excessive use of global energy sources causes negative environmental impacts and a reduction in the available energy resources. Therefore, energy efficiency is the main scope of engineering studies. Since household refrigeration accounts for a large portion of the energy consumption rate in buildings, several innovative techniques have been developed to improve the energy efficiency of vapor compression refrigeration systems. Suction line heat exchangers are considered one of these techniques and they are used to avoid the presence of liquid at the compressor and to prevent sweating on the suc ...Daha fazlası

Investigation of the Relationship between COVID-19 Illness Perceptions and Vaccine Attitudes of Midwives and Nurses Working in the Field of Women's Health

Objective: It is known that negative attitudes toward COVID-19 vaccines and unwillingness to vaccinate are higher in women than in men. Therefore, it is seen that the attitude of midwives and nurses working in the field of women's health toward vaccination is important in influencing women's attitudes toward vaccination. This study aims to investigate the relationship between COVID-19 disease perceptions and attitudes toward vaccination of midwives and nurses working in the field of women's health. Material and Method: The study was conducted in March 2021 in hospitals and primary healthcare i ...Daha fazlası
