Combination of theoretical analysis and FTIR to study the photocurrent oscillation of Silicon in fluoride media

To deepening our knowledge of the behaviour of the silicon/electrolyte interface, a study of photocurrent oscillations on silicon in fluoride concentration c F =0.033 M is realized, and as a confirmation of the result the investigation is extrapolated to a variety of electrolyte compositions. The etch rates of anodic oxides in diluted fluoride solutions have been determined by using a new approach of the analysis of anodic current oscillations. The time dependent thickness of the anodic oxide has been measured by in-situ FTIR and can be simulated considering only the time dependent current and the etch rate.To deepening our knowledge of the behaviour of the silicon/electrolyte interface, a study of photocurrent oscillations on silicon in fluoride concentration c F =0.033 M is realized, and as a confirmation of the result the investigation is extrapolated to a variety of electrolyte compositions.

A New Photovoltaic Energy Sharing System between Homes in Standalone Areas

Today, global energy consumption is dominated by fossil fuels such as oil, coal and gas. The intensive consumption of these energy sources gives rise to greenhouse gas emissions and therefore an increase in CO2 emissions. Photovoltaic energy has persistently been considered as a green and pollution-free renewable energy source to overcome greenhouse effect and energy crisis. This paper describes a new method of photovoltaic energy sharing in standalone micro-grids using photovoltaic panels. This approach is based on automatic electrical energy sharing depending on the state of charge (SOC) of the electrical storage unit using by each home and on the electrical power consumption of each home.The monitoring system is connected to each home in micro-grid, it manage each home’s energy use, and assigns more energy to a large energy-consuming home. This architecture contributes to reducing total energy lost

Implementation of an Optimized Steganography Technique over TCP/IP and Tests Against Well-Known Security Equipment

Nowadays we are witnessing a total convergence towards a digital world where information is digitized, conveyed and processed using highly developed techniques and tools. The development of broadband networks, including the internet, has made easy the manipulation, transmission and sharing of information. However, new security issues arise and they are particularly related to integrity, confidentiality and traceability of data. Facing this situation, network security has become very important and challenges related to the protection of exchanged data over the internet against unauthorized access and use have increased. In the current work, we propose to implement an optimized steganography technique over TCP/IP protocol [1]. We have also tested it against well-known security equipment using latest versions. We will see that they are inefficient to stop this kind of cover channels. Our work is like an alarm to every IT administrator to change their thinking about data lost prevention (DLP) and exfiltration of sensitive information

Design and Implementation Intelligent Adaptive Front-lighting System of Automobile using Digital Technology on Arduino Board

The automatic light AFS (Adaptive Front - Lighting System) is added to the capabilities of modern vehicles that will improve the safety of vehicle drivers and passengers traveling at night. A new architecture of the AFS has proposed in this paper. This architecture is powerful and intelligent using the PWM technique on ARDUINO Board replaces the old mechanical system based on stepper motors

Design and Implementation of Pulse Width Modulation Using Hardware/Software MicroBlaze Soft-Core

This paper presents an embedded control application of clock frequency to control the pulse width of the output signals, implemented on field programmable get array. This control allows the creation of lines of Pulse-width modulation depending on the numbers of card outputs, without using   the specific "Timers /Counters" blocks; this method is effective to adjust the amount of power supplied to an electrical charge. The purpose of this work is to achieve a real time hardware implementation with higher performance in both size and speed. Performance of these design implemented in field programmable get array virtex5 card, and Signals displayed on an oscilloscope
