The introduction of IPv6 has opened up several questions with reference to its adaption and transition from IPv4 to IPv6 and is one of the crucial issues being frequently discussed in networking community today. IPv6 provides many seamless features that makes it far better protocol as compared to its predecessor IPv4. It is a well-known fact that IPv4 is a defacto standard at present and is currently...
UML modelling tools provide poor support for composite state machine code generation. Generated code is typically complex and large, especially for composite state machines. Existing approaches either do not handle this case at all or handle it by flattening the composite state machine into a simple one with a combinatorial explosion of states, and excessive generated code. This paper presents a new...
Based on the classic embryonics electronic cell array structure, a novel structure of embryonic electronic cell array is proposed. The connections between cells are subdivided into local connection mode and remote connection mode. Cell is directly connected to its eight surrounding neighbor electronic cells in local connection mode. In remote connection mode, the signal between nonadjacent electronic...
From last several years, complex networks has been widely studied. Structural properties of network have impact on network function and many techniques are evolved to optimize network. Study of network property includes network efficiency, radius, diameter, average distance, and average clustering. All of these parameters have a direct impact on the function of the network. Finding the graph that...
Energy consumption for Cloud providers and data centers is a major problem. Dynamic Power Management is a common solution to this problem, switching off and on idle servers as needed. However, failing to predict the impact of switching costs may adversely affect energy and/or SLA violations. This paper contributes a policy that adaptively decides when to switch servers on and off under a workload...
The damped pseudo-transient analysis (DPTA) method, of step 1 up to 3 are described as they are applied to a nonlinear circuit. The DPTA method with an effective implementation based on SPICE3 is compared to the pure pseudo-transient analysis and compound element pseudo-transient analysis (CEPTA) methods, and is shown to be more efficient. The first order multi-step linear integration algorithms,...
Cortical microtubules form highly ordered structures through apparent self organisation. Two of the driving factors for this are believed to be the dynamic instability of the microtubules and the interactions that they have amongst themselves. In this paper we use a 3 state model to simulate the effect of the spontaneous growth to shrinkage rate and its relationship with the spontaneous shrinkage...
The commercial sector is responsible in a large degree for the overall energy consumption around the world and Information and Communication Technologies (ICT) constitute an important category of electricity loads which is becoming dominant in offices. Recognizing the importance of using ICT equipment more rationally for saving energy in commercial buildings, we have performed an energy audit of ICT...
The efficiency of Dual active bridge (DAB) converter is poor when it works with light load or the input voltage and output voltage are not matching with the transformer ratio. A novel one side single half bridge pulse-width-modulation plus phase-shift (HPPS) switching strategy is proposed in this paper to improve DAB work efficiency. The operation principle is demonstrated, and its power mathematic...
A novel two winding coupled-inductor step-up gain boost-flyback converter is proposed in this paper. The proposed converter consists of a boost cell and a flyback cell, with a two winding coupled-inductor to achieve high step-up voltage gain at reasonable duty ratio. The voltage gain of the proposed converter is improved with input-parallel output-series of two windings of coupled-inductor. The operating...
A novel high step-up three-port converter is proposed in this paper. By utilizing coupled-inductor technique, voltage lift technique and multi-winding technique of coupled-inductor. However, main switch suffer from high voltage spike during the turned-off period. Hence, for suppressing and recycling the energy, the clamp circuit technique is applied. Finally, the prototype of the proposed converter...
Multilevel inverters are one of the most popular and useful type among all and have lots of usage like less disturbance and the possibility to function at higher switching frequencies than ordinary two-Level inverters. They can be used at different applications like electronic derivers, wind turbines and solar plants. In order to feed the DC current produced by PV panels to the inverters, power electronic...
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...
