Introduction
Hayriye Korkmaz currently works at the Department of Electric-Electronic Engineering (Tech), Marmara University. Interest fields are as follows: Electronic Engineering, Instrumentation Engineering and Vocational Education.
Their current project is development of a Remote Lab for Electronic Circuit Design and Analysis Course with Increased Accessibility by using Speech Recognition Technology a part of a PhD Thesis. In this project, we have almost completed the Voice and Remote Control of Programmable Instruments available in the lab. For example, handicapted students can adjust the Volt/div knob position of the oscilloscope just by speaking without using his hands.
Second project is about biomedical engineering. Tasks are as follows: 1) to set up a HIFU driver instrumentation 2) to perfo

Background
Ankylosing spondylitis (AS) is a chronic inflammatory disease affecting the sacroiliac joints and spine, often leading to disability if not diagnosed and treated early.
Objective
In this study, we present the development and validation of machine learning (ML) algorithms for AS detection only using Short Tau Inversion Recovery (STIR) se...
Engineering can enhance students' theoretical knowledge and practical application skills when integrated into K‐12 education. This approach encourages students to contemplate technology and engineering in more depth.

When the curricula of engineering undergraduate programs are examined, it can be seen that experimentation plays a very important role and the learning outcomes of the courses are mostly dependent on practical abilities. However, there may be a few who cannot use their hands permanently or temporarily among the students who are attending these cour...
BLDC (Brushless Direct Current) motors are widely used today due to its high reliability and high efficiency. These motors are synchronous motors that have a linear relationship between voltage-speed and current-torque. To control these kinds of motors, inverters are needed. Inverters create a rotational movement in the motor by switching at the ap...

Background:
In the classical process, it was proven that ABPM data were the most significant attributes both by physician and ranking algorithms for dipper/non-dipper pattern classification as mentioned in our previous papers. To explore if any algorithm exists that would let the physician skip this diagnosis step is the main motivation of the stu...
In 2005, global cardiovascular diseases caused 30% of deaths in Europe, which is 46% of total deaths for all death groups. Today, according to the International Adult Diabetes Federation, 20% to 25% of the adult population in the world has Metabolic Syndrome. Turkish Statistical Institute claims that in Turkey 408782 people died of circulatory syst...
The purpose of this work is to add a new feature to bench-type conventional instruments used in Electrical and Electronics Engineering Laboratory which do not have any voice recognition and wireless communication technology.

Özetçe— Son yıllarda Yüksek Şiddetli Odaklanmış Ultrason (HIFU) bazı kanser türlerinin tedavisi için klinik uygulamalarda aktif bir şekilde kullanılmaya başlanmıştır. Bununla birlikte, diğer kanser tedavi yöntemlerinde olduğu gibi tedavinin etkin bir şekilde gerçekleştirilebilmesi için dozimetrik çalışmaların yapılması gerekmektedir. HIFU uygulamal...
Background
It is possible to see a number of spectrophotometers produced by commercial purposes developed in line with the technical advices identified by the International Commission on Illumination (CIE) in universities’ chemistry labs. These devices are employed in measuring and testing materials with unidentified characteristics as well as repo...
For HIFU treatment devices, it is essential to perform temperature characterization in tissue-mimicking phantom systems (Tissue-mimicking material, TMM) in pre-clinical studies. In this study, temperature distribution inside a TMM induced by a HIFU (High Intensity Focused Ultrasound) transducer was investigated with two different T-type thermocoupl...
Abstract— Realization of temperature characterization on focused ultrasound treatment devices by using tissuemimicking phantom systems (Tissue-Mimicking Material, TMM) is indispensible in pre-clinical studies. In this survey, in order to examine the viscous heating effect of thermocouples, temperature rise due to excitation of a HIFU transducer has...
This paper presents a web-based interface for disabled students. When the curriculum of engineering faculties are examined, it can be seen that practice takes important place and learning outcomes of the courses is mostly depend on hand ability. In particular, the implementing and testing the electronic circuits in both real and simulated environme...

This study proposes a system using RFID and XBee technology to address and eliminate the problems resulting from human errors in put-away operations. The human errors in such operations are a serious problem that leads to a number of difficulties in production lines and supply-chain. The use of automated verification system in put-away operations i...
Diabetes Mellitus (DM) is a high prevalence disease that causes cardiovascular morbidity and mortality. On the other hand, the absence of physiologic night-time blood pressure decrease can further lead to morbidity problems such as target organ damage both in diabetics and non-diabetics patients. However, the Non-dipping pattern can only be measure...
