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.

Konuşma Tanıma (KT) alanındaki bilimsel ve teknolojik gelişmeler, yaşamın her alanında kullanıcılara büyük kolaylıklar sağladığı gibi eğitim alanında da kendine önemli bir yer bulmaktadır. Temel olarak bir KT sistemi, öncelikle konuşma verisini almak ve söyleneni tahmin etme işlevlerini yerine getirir. Ardından konuşulan kelime ve ifadeler sayısal...

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...
