This paper discusses steady state optimal control of the motor from the maximum torque point of view. The motor behavior is researched with a vector control supply in the full speed range. The optimal considerations are compared with a behavior of the classical control structu...

This article describes experimental measurements of a skin temperature in vicinity of a surgical wound. Measurements were carried out in collaboration with the orthopedic department of the University Hospital Olomouc, Czech Republic. A system used for sensing, transmission and visualization of&#x...

The purposes of the paper are to contribute to the understanding of the notion of anisotropy of images and to expose details on a method for deriving global and local statistical features on materials, based on anisotropy. We introduce a definition of anisotropy related to...

The aim of this paper is to present a system powered by a Raspberry PI and an industrial robotic arm, which can execute numerous task in a factory. The used robotic arm and imaging devices are industrial type, but the control system it's a simple development micr...

Human movement analysis is a research field with clinical and biometrics application. It has been shown useful in the objective measurement of gait, balance, falls risk assessment and mobility monitoring. Running and/or walking are also integral activities to most athletic disciplines. ...

This paper deals with dissipativity, stability, chaotic behavior and related structural properties of a relatively broad class of finite dimensional strictly causal systems. The class of nonlinear systems under consideration is described in the state-space representation form. System properties are&#x...

This work presents a simple study of stochastic arithmetic complex number operators for addition and multiplication. Their usage is demonstrated by design of a sum of product circuit As the stochastic complex number operators need more control random streams than stochastic rational num...

This paper presents a new topology for waveform-generation using two current conveyors, and a grounded capacitor or a resistor for tuning. It uses current-conveyors in place of voltage op-amps to offer better linearity, bandwidth, slew rate and thermal stability. Measured results obtained&#x...

The efficiency is the most important factor which is to maximazed during the wireless energy transfer system development but also at the other electronics devices. Therefore this artice deals with the most suitable working point analysis of such a system. The center of the art...

This paper presents two new applications of modified version of the voltage differencing current conveyor (VDCC) active device in electronically linearly controllable quadrature oscillators. In this particular case, VDCC element is modified in such a way that it uses electronically adjustable...

In this study a new frequency hopping scheme which relies on digital up-conversion of baseband data is proposed. Since the frequency of the local oscillator is kept constant and hopping is achieved in the baseband, the time required for the frequency jump is independent of...

In this paper, a low-cost localization system designed for mobile robots is introduced. The system has been developed for a teaching aid where a mobile robot operates in a maze. The mobile robot is navigated by a high level control system where path-planning is executed; ...

In the present paper a preliminary design and implementation of a readout interface for strip detectors, using Applied Specific Integrated Circuits (ASICs) is discussed. Key issues are the parameters and features of the main constituent parts of the system: strip detectors, ASICs and&#x...

In this paper a structure for direct 4-BIT XOR/XNOR logic cell is proposed. This structure is proposed using pass transistor logic with FinFETs. This structure has less delay for the reason that its critical path consists of a minimum number of transistors. The basic adva...

Traditionally, fieldbus networks are operated in closed environments, where all communication nodes are assumed to be trustworthy. Therefore, the corresponding standards do not consider any security requirements. New technology trends, such as the upcoming Internet of Things (IoT), demand an inte...

In this paper, we present and compare the design and the performances of ten different implementations for a 16-bit adder in a 180nm CMOS standard-cell technology. Ripple carry adder, increment adder, triangle adder, uniform and progressive carry select adder, uniform and progressive ca...

This paper briefly describes possibility to use band-pass and notch filters with low quality factors for straightforward synthesis of the so-called constant phase elements. These filters connected in cascade can form desired alternation of transfer function zeroes and poles. Using proposed a...

This article deals with Internet of Things as an integration platform for embedded systems. The problem of traditional hierarchical communication is challenged by direct peer-to-peer communication model among various embedded devices. CoAP protocol is selected as a potential candidate to meet...

In presented paper we describe a design and implementation of an information system based on base of embedded client and Linux application server architecture. Presented information system serves for remote collection, storing and processing information on the number of carried out mechanica...

The paper addresses the design of a bulk-driven variable gain amplifier (VGA) in 130 nm general purpose CMOS technology. The VGA is intended to be employed within a low-power automatic gain control (AGC) block, which requires an examination of possible gain setting approaches. The&...
