Abstract:
It is trend that the mode of heat charging is changed from billing by building area to by thermal energy. In order to meet the needs of heat charging mode changing， a new system of heat charging based on IC card is proposed. The user?蒺s energy consumption is calculated by measuring the user inlet and outlet temperature and flow，using the IC card to record the prepaid amount and the current price of heat. The user?蒺s heating costs is calculated according to energy consumption and current price， according to actual heating costs and prepaid amount，the system controls the heating opening or stopping. It is more reasonable that calculated heating costs by user heat consumption

PNG開放源接口 The interface has
been designed to be as simple and intuitive as possible. It supports plotting and reading in the RGB (red, green,
blue), HSV (hue, saturation, value/brightness) and CMYK (cyan, magenta, yellow, black) colour spaces, basic
shapes, scaling, bilinear interpolation, full TrueType antialiased and rotated text support, bezier curves, opening
existing PNG images and more.
A dissipative particle swarm optimization is
developed according to the self-organization of dissipative
structure. The negative entropy is introduced to construct an
opening dissipative system that is far-from-equilibrium so as to
driving the irreversible evolution process with better fitness.
The testing of two multimodal functions indicates it improves
the performance effectively.

This collection of 28 research papers provides an insightful overview of past and current research findings in Project Management, and takes an eye-opening excursion along frontiers fertile for future investigation.
In the bank all the activities are being done manually .As the bank widens its services & it finds difficult to manage its operations manually and hence this leads to the automation of some of its operations.
Banking Information system is a windows based applications. This project mainly deals with managing there types of account such as Saving Account, Current Account and Recurring Deposits .
In this project bank is seeking to manage these account through computer based system.
Tasks involved in this project are opening the user accounts , recording the account holders transactions , modify, the user records and generating the reports .
This project is having three module:
] 1. Bank Master Module
2. Transaction Module
3. Reports module

SharpPcap c#抓包實(shí)現(xiàn)時時獲取網(wǎng)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
