A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.
SOME BACKGROUND ON DESIGN PATTERNS
The term “design patterns” sounds a bit formal to the uninitiated and
can be somewhat off-putting when you first encounter it. But, in fact, design
patterns are just convenient ways of reusing object-oriented code between
projects and between programmers. The idea behind design patterns is
simple-- write down and catalog common interactions between objects that
programmers have frequently found useful.
Electronics Design Checklist
C) 2003 Hank Wallace
This is a checklist for electronics designers. The idea is for engineers and technicians to
share experiences and create a detailed checklist, which the individual designer can pare down to meet his or her specific needs. There are many details that go into the making
of a first-run design success, and this checklist helps prevent Murphy s gremlins from
marring an otherwise healthy design.
Argh! Where s my mouse? Ah look at the eyes .... there it is! )) Mouse Eyes is another mouse cursor follower. Mouse eyes idea is indicating which direction to look in to find your mouse cursor.
In this work an implementation of a geometric nonlinear controller for chaos synchronization in a Field Programmable Gate Array (FPGA) is presented. The Lorenz chaotic system is used to show the implementation of chaos synchronization via nonlinear controller implemented in a Xilinx FPGA Virtex-II 2v2000ft896-4. The main idea is to design a nonlinear geometric controller which synchronizes a slave Lorenz system to a master system and then implement them into the FPGA.
Description
Combination of book reader and Web browsers.
This program can be used for Web browsing, reading news sites, downloading and reading books and atricles from the Web. It is not implement all HTML browser functionality - it doesn t show images and is not able to proceed forms. The main idea was to make it possible to view normal sites (not WAP sites) on very small screen of mobile phone. This application share a lot of code with MobiReader and first of all is inteded to be used to browse text data.
SharpPcap c#抓包實現時時獲取網卡信息
SharpPcap tutorial: a step by step guide to using SharpPcap
The text of this tutorial is taken directly from WinPcap's official tutorial but is modified to show the C# use of the SharpPcap library. All examples can be downloaded together with SharpPcap source code from SharpPcap 's homepage. The WinPcap library must be installed before attempting to run any of these examples, so please download and install the latest version from WinPcap's download page.
SharpPcap was written and tested using .NET v1.1 and Windows 2000/XP. I have no idea about other .NET and Windows versions. If you do try it, please report your results.
The following topics are covered in this tutorial:
Obtaining the device list
Obtaining advanced information about installed devices
Opening an adapter and capturing packets
Capturing packets without the event handler
Filtering the traffic
Interpreting the packets
Handling offline dump files
Sending Packets
Gathering Statistics on the network traffic
1. Obtaining the device list
We introduce a sub-cell WENO reconstruction method to evaluate spatial derivatives in the high-order ADER scheme. The basic idea in our reconstruction is to use only r stencils to reconstruct the point-wise values of solutions and spatial derivatives for the 2r-1 th order
ADER scheme in one dimension, while in two dimensions, the dimension-by-dimension sub-cell reconstruction approach for spatial derivatives is employed. Compared with the original ADER scheme of Toro and Titarev (2002) [2] that uses the direct derivatives of reconstructed polynomials for solutions to evaluate spatial derivatives, our method not only reduces greatly the computational costs of the ADER scheme on a given mesh,
but also avoids possible numerical oscillations near discontinuities, as demonstrated by a number of one- and two-dimensional numerical tests. All these tests show that the 5th-order ADER scheme based on our sub-cell reconstruction method achieves the desired accuracy, and is essentially non-oscillatory and computationally cheaper for problems with discontinuities.
