Pink noise, which has a power spectral density that is inversely proportional to the frequency, is widely used for acoustic applications such as for testing audio equipment. Its generation from white noise requires such a system transfer function that it is no…
Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…
The quality control process for determining fabric faults causes high cost and time loss when performed with human eyes. Adding a real-time system to the fabric production mechanisms is very difficult to detect mistakes. In this study, 5 MP Raspberry Pi camera…
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…
In this study, the accelerations caused by the diaphragm movements during respiration were monitored with a 3-axis accelerometer and the measured accelerations were recorded on an SD card. A measurement system for this purpose was developed. The moments in whi…
Bu çalışmada, robotik uygulamalarda yaygın bir şekilde kullanılan kapasitif rotary enkoder anlatılacaktır. Kapasitif rotary enkoderler hem açısal pozisyon hem de açısal hız ölçmede kullanılmaktadır. Enkoder temel olarak 3 ana parçadan oluşmaktadır: 1. komple i…
In the last decade, deep learning in general and Convolutional Neural Networks (CNN) have achieved a human level and outstanding performance in almost all computer-based systems such as classification(text, images, and videos). Building an efficient CNN archit…

Bu çalışmada, non-lineer ve dengesiz yükün bulunduğu güç sisteminde aktif filtre kullanılarak harmonik distorsiyonun değeri düşürülmüştür. Pasif harmonik filtrelerin aksine, modern aktif harmonik filtreler, güç faktörü düzeltme, gerilim regülasyonunu saglama…
We have designed a portable low-cost stethoscope with software tools. It is aimed to pre-diagnose heart diseases in a short time without exposing the patient to detailed examinations and additional procedures such as electro-cardiography (ECG) or angiography. …
Oscillators are one of the most important basic circuit blocks frequently used in electrical-electronics engineering applications. Among several types of the sinusoidal oscillators, quadrature oscillators are frequently used in communication circuits, control …
The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …
In this study, mathematical modeling of an ohmic heating system has been done, firstly. Then, two different control approaches, PID and fuzzy logic control, have been considered to control of mathematically modeled ohmic heating system. An optimal PID controll…
İnsan ve bilgisayar etkileşimi, interaktif teknolojilerin tasarımı, değerlendirilmesi ve uygulanması ile ilgilenen disiplinler arası bir çalışma alanıdır. Bankalar, hastaneler, okullar, internet siteleri gibi hayatın her alanında insan ve bilgisayar etkileşimi…
With the rapid development of technology and the importance of electronic devices in our lives, electromagnetic waves produced by various sources and the related electromagnetic pollution concepts have become an important issue that directly affects the nature…
The updated structural discontinuities of Turkey are determined utilizing Bouguer gravity data in this study. Total horizontal gradient technique was used to reveal the lineaments. This technique is applied to first vertical derivative values of regional gra…
In this paper, a boundary version of the Schwarz lemma has been considered for driving point impedance functions at s = 0 point of the imaginary axis. Accordingly, under Z(0) 0 = condition, the modulus of the derivative of the Z s ( ) function has been consi…
Elektrik sistemlerinin arızasız ve güvenli bir şekilde çalışabilmesi, akım ve gerilim gibi devre büyüklüklerin 50 Hz frekansta ve sinüsoidal formda olmasına bağlıdır. Bununla birlikte bir çok nedenlerden dolayı bu temel büyüklükler sinüsoidal özelliklerini k…
It was aimed to find the structural discontinuities of the Eastern Anatolia Region by using horizontal gradient magnitude technique. When determining the structural discontinuities of the region, the maximum amplitudes of the horizontal gradient magnitude we…
