To accomplish control tasks, an emerging innovative method of automation is voice control. In conjunction with Lab VIEW [1] and Windows Speech recognition [2], the two most human interactive activities; drawing of curtains and switching on and off of lights are controlled. This will help in improving living standard by making living easier for elderly people, reducing frustration and increasing independence...
This paper is dedicated to the presentation of the Tempus project “rESeau maghrébIn de laboratoirEs à distance”, eSience, which aims to create an eLab for the realization of remote practical courses in Maghreb countries (Algeria, Morocco, Tunisia). In this paper, we present a prototype for a remote laboratory for electronics implemented in the National Electronics and Telecommunications school of...
Adaptive open learning technology provides adaptive methods of interacting with the technology used in open learning. Since most of online learning systems are computer-based, adapting the keyboard for people with special needs will be of great effectiveness. This article presents an adaptive keyboard technology based on Morse code that will enable users with physical disability or functional limitations...
An effective voltage regulation circuit for inductive power transfer systems was proposed in this paper. The circuit takes the advantage of the secondary coil and a switch component and a capacitor was added. The relationship between output voltage and duty cycle of switches was analyzed and verified by simulation.
Nowadays, the number of severe disabled (a totally dependent or assisted living) is dramatically increased due to the increasing rates of accident and brain disease. Therefore, this paper proposes a novel modality of brain-computer interface (RCI) system as an alternative assistive tool for the severe disabled. The use of EEG based emotional and arithmetic imagery from the pre-frontal area is employed...
This paper presents a developed experimental system using an eye-tracking device, by which we can control displayed visual stimuli flexibly like visual trick. Using this system, comparisons between two faces with different expressions are experimented in a specific condition as one face is always forced to display as in the subject's central field of view, while another face is always displayed in...
In model-based design of cyber-physical systems, such as switched mixed-signal circuits or software-controlled physical systems, it is common to develop a sequence of system models of different fidelity and complexity, each appropriate for a particular design or verification task. In such a sequence, one model is often derived from the other by a process of simplification or implementation. E.g. a...
Infants often synchronize rhythm pattern of their body movement with their caregivers. Developmental scientists assume that infant-caregiver body synchrony is a fundamental factor for maturing their close relationship and it facilitates social development of infants [1–2]. When multiple individuals are in synchrony, they tend to mimic each other's behavior [3]. One agent generates own behaviors on...
Local control center simulator to test an improved train control system using on-board control is discussed here. Improved train control system using on-board control developed to improve efficiency of train operation is a technology to control wayside objects directly from on-board controller. Introduction of this system will simplify wayside structures, leading to efficient and cost-effective train...
□ No power conversion without power semiconductors □ Power semiconductors is NOTHING without a gate driver! □ The gate driver will properly drive a power semiconductor and bring the maximum performance. For WBG devices, • Driving capability of gate driver IC (rise/fall time, pull-up/pull-down resistance) & CM transient immunity of gate driver isolation are special requirements. □ The gate driver...
The paper is devoted to investigation of the pulse modulated systems with constant impedance load based on the application of auto-transformers in the primary circuit of pulse converters allowing to provide operation of a system with restricted range of modulated load signals and such operation conditions allow to obtain better electro-magnetic compatibility of converter with AC network without application...
This paper presents a bidirectional double-boost dc-dc converter with higher efficiency for renewable energy applications. The proposed converter uses a non-dissipative RCD snubber, that not only reduces the voltage stress but also provides better efficiency to the converter. This bidirectional double-boost dc-dc converter operates under two modes namely charging and discharging. Under both charging...
The innovation ecosystem is often seen as a ‘pipeline’, or in other words, a linear commercialization model that goes from idea to the marketplace with stages in research, proof-of-concept development, prototype, product beta-testing and market launch. This often works for ‘technology push’ projects that commonly begin not with a discovery, but with the identification of a market need that triggers...
Combination of renewable energy sources with utility grid and/or energy storage systems can deliver continuous power to the loads. Since many energy sources and loads use dc, it is envisioned that future smart homes may have dc distribution systems in order to interconnect various energy sources, storage, and loads with fewer converter stages and higher energy efficiency. In such applications, the...
A comprehensive examination of the mathematics courses undergraduate engineering majors take in their first two years, and their success in those courses was conducted to determine the impact of course level and grade on student persistence in engineering. Six hundred fifty five, full-time freshmen enrolled as engineering majors at a major university in the Southwest United States participated in...
In this paper, a single-phase rectifier topology based on a five-level four-switch converter is proposed. Such topology will be called as 5L-4S Rectifier, which presents some advantages over the traditional ones, such as lower THD of the grid current due to high number of levels generated at the grid side and lower power switching losses. The complete analysis presented in this paper includes the...
Higher education institutions often describe goals for the student experience as a whole as well as define and guide the academic requirements to earn a degree. This paper seeks to ignite discussions on how lean engineering principles can improve the collegiate student's academic or educational experience. We explain how the principles that drive lean engineering can be operationalized in the context...
Safety requirements have commanded increasing attention as software is playing a more and more important role in today's safety critical systems. As many experts, scholars have found that the main reason for safety critical systems' accident is bad requirements which means inaccurate, incomplete or inconsistent requirements may lead to misunderstanding of the system and may cause a fault in software...
The study was to compare the characteristics of event-related potentials (ERPs) and brain topographic maps in normal group and cochlear implant (CI) group six months after device ‘switch on’. Results showed more negative N1 component by standard and target stimuli and lower P2 amplitudes were observed for the CI group. The amplitudes of MMN component were a little smaller than those of normal group...
Voltage is one of the most fundamental concepts in electrical engineering, but nevertheless has been shown to be a difficult concept for many students. To help address those difficulties, we designed a tutorial worksheet similar to those published by the Physics Education Group at the University of Washington. In this activity, students were introduced to electric potential and compared and contrasted...
