Control and simulation of swarm mobile robots

Şen, Hayrettin

This thesis presents both control of mobile robots that can move by using collective motion algorithm and simulation of the robots during the motion. The orientation of the robots was controlled remotely by one user during the collective motion. The transmission of orientation data from the remote controller to the robots was done by using XBee modules. The control algorithm of collective motion was developed by using individual-based model. Two modes are considered during the control. These modes are search and swarm mode. The collective motion was performed by robots that are moving with re ...Daha fazlası

Group effect in axially loaded chemical anchors embedded in low strength concrete

Arslan, Tolga

The use of chemical anchors for the connection of existing structural elements with the new elements during strengthening of existing structures is quite a preferred method. Since in our country, chemical anchors are being widely used for repair and strengthening works, there should be a standard of design and application on this topic. Up to now, research done on the topic of chemical anchors, are mostly carried out on concrete blocks of compressive strength 20 MPa and higher. Since parameters such as distance from the edges, embedment depth and group effect were mostly ignored, the re ...Daha fazlası

Investigation of concrete barriers with recycled rubber, steel slag and roof tile

Kurar, Ali

The purpose of aggregating rubber is to increase concrete’s flexibility, elasticity, and capacity to absorb energy. In some application of concrete, it is desired that concrete should have low unit weight, high toughness and impact resistance. Although concrete is the most commonly used construction material, it does not always fulfill these requirements. In order to improve elastic properties of concrete and recycle the waste materials, new applications have been realized recently. One of these applications is the utilization of discarded tires in order to use together with aggregate. ...Daha fazlası

Expert system design by using artificial intelligence techniques for the diagnosis of liver disorders

Mülayim, Naciye

Nowadays, Expert System (ES)s are used widely in many areas to solve real world problems. Artificial Intelligence (AI) techniques are used to obtain timely and accurately decision about solution of daily problems in ESs designing because AI can mimic behaviours and thought system of people. Especially in medical area, there are many researches and applications using ESs based on various AI techniques to obtain diagnosis for any diseases. The liver is a vital internal organ for a human body and it has many functions, which are associated with the other organs. Although the liver can renew itse ...Daha fazlası

Fuzzy logic modelling of sediment transport in annulus

Müftüoğlu, Tevfik Denizhan

The understanding of sediment transport with fluid in pipes is one of the important issues in hydraulics engineering. If the fluid velocity is lower than a critical value, a stationary cuttings bed develops, which may cause excessive head loss. In this study, a Fuzzy Logic (FL) model is developed to estimate stationary cuttings bed thickness inside the annulus. Experimental data is collected from literature in order to train proposed models. Results showed that the cuttings bed thickness could be estimated using the developed model with a reasonable accuracy when compared with the experimental ...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

Olive leaf powder and boron reinforced polypropylene composites Zeytin yaprağı tozu ve bor katkılı polipropilen kompozitleri

Kara, Hilal

SUMMARYPlastics have a wide application area in our daily life because of the properties such as being inexpensive, lightweight and easy to take shape. Plastics can lead to some problems such as endangering human health and reducing the life of the material, because the plastic surfaces are so available for microorganisms to form a biofim by holding onto the surface easily. Researches for antibacterial materials containing various natural and inorganic substances has been increased and become more important because of that people are often infected by microorganisms such as bacteria, molds, ye ...Daha fazlası
