Technology for modifying the local temperature of a material is tested for hot forming. A system for selective controlled cooling was designed for this purpose and a workplace enabling heating, local cooling and material forming was built. This paper describes the principles and po...

The development of machine tool is toward high-speed, high-precision and smarter with high-end compensation techniques. The sensor and the data acquiring system are required in compensation system. However, the aliasing phenomenon can be observed in the existing data acquiring system in mach...

A new indirect frequency converter is introduced in this paper. The main goal of the new proposal is to simplify installation and running as supply unit for industrial applications. It fulfills minimum dimensions requirement and also enables parallel connection and full energy recuperat...

We have investigated the influence of emotions on the level of correlation of the vowel formants in the Romanian language during dynamic pronunciation. We have used in the analysis the sentence /vine mama/ (mother is coming), which is a commonly used phrase in the da...

QR Codes are used as information channel on several cryptographic architectures due to their technical properties, such as data capacity and retrieval reliability. This paper presents a novel string data validation system using QR Codes and meaningless reversible degradation. The proposed sc...

Biphasic constant current (CC) stimulators are used in functional electrical stimulation applications. These stimulators require positive and negative high voltage (HV) sources in order to deliver the programmed CC pulses to load. For example, applying symmetrical biphasic CC pulses with 50 ...

The paper presents the basic layout for instrument current transformer calibration using comparative method with a standard. The error difference is evaluated using electronic transformer test sets. Calibrating procedure of these systems using error simulation is also described. In conclusion, re...

Converter losses play a crucial role in the process of power converter design. Especially semiconductor components and heat sink selection are strongly dependent on the total power converter losses and thus affect the power converter size and its price. The most popular techniques ...
