To follow the class attendance of the students is a challenging and time consuming process in terms of lecturer. Followup of class attendance at universities is done by circulating the attendance sheet in class. The number and signature of each student is got.…

The health need is undoubtedly an indispensable necessity for human life. When the literature is examined, it is seen that various health monitoring systems are developed by helping to meet the health need with technological improvements. Some of these studies…

The mobile processors with the increasing computational capabilities and software supports for the devices equipped by them have attracted the researchers’ attention to check whether they can be used for solving complex problems or not. In this study, a mobile…

This study presents the modelling of the pathological elements based memelements. More than forty years ago, Chua predicted the existence of memristor (memory+resistor) which is the fourth fundamental passive circuit element. In 2008, Hewlett Packard (HP) rese…

Developing technology, and electronic devices, power consumption is increasing day by day. At the present time, there are many methods used to generate electricity. Most of these methods cause environmental pollution. The share of thermal power plants in elect…

This paper describes innovative and novel trends on engineering education. Among these trends internet-based engineering laboratory with virtual and physical experiments, smart classes, 3G/4G technologies, and e-learning and m-learning facilities can be expres…

One of the most consumed energy sources today is fossil-based fuels. While the reserve of these fuels is declining, it continues to be the main cause of environmental pollution. Due to the influence of environmental factors and increases in fuel costs has acce…

Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term …

In order to increase the performance/cost ratio of solar cells, new approaches reducing optical and electrical losses are necessary during the absorption of the light and collection of charge carriers. In this work we focused on various textures on Si surface …

When the traditional fuel reserves are limited and the environmental factors of these fuels are taken into consideration, the importance of renewable energy sources is increasing day by day. Especially, obtaining electricity from solar energy has become popula…

Today, the number of dialysis units that can meet the needs of kidney patients, in parallel with this, qualified staff in the sector his need is increasing day by day. In order to meet this need, dialysis programs have been opened within the University. The ai…

Nowadays, home automation systems are one of the areas where technological developments are applied. Thus, devices such as doors, windows, lighting, heating, cooling, security cameras, elevator, fire, water pressure, garage, solar energy systems and TVs, curta…

The monitoring of emissions caused by congested road traffic requires the deployment of a complex measurement system. The use of Wireless Sensor Networks (WSN) can be very useful. In this work we propose the architecture of sensors (devices) which are envisage…

Cementation steels; surface hardness is high and abrasion resistant materials.Also, cementation steels are materials with the alloyed or non-alloyed structure which materials used in the manufacture of parts which are resistant to shock and variable loads.Addi…

In this study, abrasive wear behaviors of Co-Cr-Mo alloy (ASTM F75) which is produced by casting method, were investigated. The prepared test samples were subjected to abrasive wear tests with different emery papers on the pin on disc wear device. In the abras…

In today’s developing world, capital needs, which are essential to fulfill an enterprise, still pose a problem despite the subsidies and special funds. The aim of this study is to analyze to what extent the subsidies of SMIDO in Tokat province, which is situa…

Yenilikçi soğutma teknolojileri arasında yer alan ısı boruları, sahip olduğu özgün karakteristikler sebebiyle son yıllarda önemli bir araştırma alanı olarak ortaya çıkmaktadır. Isı boruları, taşınımla ısı geçişi ve sıvı-buhar faz değişimi ilkelerinden faydalan…

Energy conversion systems are very diverse. One of the most important of these systems is undoubtedly the electric machines. Mechanical energy production from electricity has been ongoing for about 150 years. With rapid developing technology, it has shown a ra…

In this study, thermodynamic analysis of a geothermal power-based district energy conversion system which produces electricity, hot water, heating and cooling are investigated. The energy produced from geothermal resource can be utilized to drive a double stag…

Güç sisteminde akım ve gerilimin dalga formunun sinüsoidal formda olması gerekir. Fakat bu her zaman mümkün olmaz. Non-sinüsoidal gerilim veya elemanlar güç sisteminde harmoniklerin oluşmasına sebeb olur. Harmonikler güç sisteminde, ek ısıl kayıplara, rezona…
