Robots are used to make human life easier. In our daily life, the work done with classical machines is done with autonomous robots by reducing human intervention. Thanks to the network infrastructure, remote command operation and communication with each other can be provided. It is also possible to do the work done with only one robot in a shorter...

The demand for renewable energy sources is increasing day by day due to the gradual decrease of fossil-based energy sources, increasing costs and environmental problems. Recently, electricity generation from solar and wind energy has become more preferred in many countries. Photovoltaic panels are used in the conversion of solar energy directly int...

Course timetabling problems are one of the optimization problems and these are also known as NP-Hard problems. A Course timetabling problem consists of many parametric optimizations to be considered. Due to the complexity of optimization, many timetabling problems are done manually by one of an experienced person. In this paper, solving the timetab...

Exam timetabling problems are one of the optimization problems and these are also known as NP-Hard problems. An exam timetabling consist of different constraints and satisfactions from course timetabling. In university exams, one of the significant difference from courses are exams can be done used multiple classrooms while courses use only one. In...

In this study, we aimed to detect and count similar objects in an image. Object images are obtained from conditioned environment that camera position and lighting are fully controlled. Variously shaped objects can be in any position and direction on black plane. Model object is selected by user from image on screen. User simply draws a selection bo...

Aim: The aim of this study is to design and implement a system that detect driver sleepiness and warn driver in real-time using image processing and machine learning techniques. Material and Method: Viola-Jones detector was used for segmenting face and eye images from the camera-acquired driver video. Left and right eye images were combined into a...

Bu çalışmada, Trakya Üniversitesi laboratuvarlarında bulunan Yüksek Performanslı Hesaplama Sistemi (TRAKYAHPC) altyapısı kullanılarak, Windows HPC işletim sistemine sahip sunucular üzerinde çalışan bir dağıtık görüntü işleme uygulaması geliştirilmiştir. Bu uygulama kullanılarak iki farklı görüntü veri tabanındaki toplam 4640 görüntünün her biri içi...

Aim of this study is obtain calculable maze path data from a maze image or taken maze photo. Image of maze can be a viewable natural maze or previously produced or pressed maze. After digitalization of maze image, image processing techniques are using to analyzing maze walls or lines. Bird's eye view correction can be applied if photo is not taken...

Kumdere is a village located in İpsala, Edirne Turkey. This village's drinking water needs is provided with drawn water from the well. Water in the well is sent to the tank by a pump. The water, located in tank, meet the drinking water needs of the village. Pump system used, takes energy from the grid. In this study, a feasibility study was conduct...

Doğrusal motorlar mekanik tahrik amacıyla kendine farklı uygulama alanları bulmuştur. Bununla birlikte, fırçasız DC motorlarda olduğu gibi, doğrusal fırçasız motorlar da elektronik anahtarlama yoluyla kontrol edilmeye ihtiyaç duyarlar. Bu çalışmada, doğrusal bir DC motorun kontrolünü sağlayan gömülü sistem tasarlanmıştır. Tasarım aşamaları, elektro...

In this study, we aimed to classifying basic hand signs with image processing techniques. Hand images were obtained from a camera and each signs were classified manually for creating learning samples. Gabor wavelets were used to extract features of each hand sign image. Meaningful features were selected for teaching machine learning algorithms whil...

In this study, a design, flexible and can work on many platforms, has been made for process control education. Design is an electronic board, communicated with equipment of proses control training set made by the Bytronic. Electronic card is capable of such these features; sensor reading (PT100), temperature control and fluid flow control etc. Soft...

Productive agriculture needs technologies. Technologies are using in agriculture in several stages. In this study, classification of rice grains were tested using image processing and machine learning techniques. There are three grain types used for classification. But broken grains were considered as a type too. Thus total of 4 grain types were us...

Applied computer laboratory lessons could be unproductive because of many students in there. Correcting students’ mistakes one by one is wasting lesson time. Especially for beginners, most of these mistakes caused by complex integrated development environments. In this study, we develop a client server application for computer laboratories. Develop...
