DtWinVer is a C++ class which provides a comprehensive method to determine which OS the program that calls it is running on. All methods it uses are fully documented on various articles on the MSDN CD
Description
The art galleries of the new and very futuristic building of the Center for Balkan Cooperation have the form of polygons (not necessarily convex). When a big exhibition is organized, watching over all of the pictures is a big security concern. Your task is that for a given gallery to write a program which finds the surface of the area of the floor, from which each point on the walls of the gallery is visible. On the figure 1. a map of a gallery is given in some co-ordinate system. The area wanted is shaded on the figure 2.
The BNL toolbox is a set of Matlab functions for defining and estimating the
parameters of a Bayesian network for discrete variables in which the conditional
probability tables are specified by logistic regression models. Logistic regression can be
used to incorporate restrictions on the conditional probabilities and to account for the
effect of covariates. Nominal variables are modeled with multinomial logistic regression,
whereas the category probabilities of ordered variables are modeled through a cumulative
or adjacent-categories response function. Variables can be observed, partially observed,
or hidden.
Many CAD users dismiss schematic capture as a necessary evil in the process of creating
PCB layout but we have always disputed this point of view. With PCB layout now offering
automation of both component placement and track routing, getting the design into the
computer can often be the most time consuming element of the exercise. And if you use
circuit simulation to develop your ideas, you are going to spend even more time working on
the schematic.
observable distribution grid are investigated. A distribution
grid is observable if the state of the grid can be fully determined.
For the simulations, the modified 34-bus IEEE test feeder is used.
The measurements needed for the state estimation are generated
by the ladder iterative technique. Two methods for the state
estimation are analyzed: Weighted Least Squares and Extended
Kalman Filter. Both estimators try to find the most probable
state based on the available measurements. The result is that
the Kalman filter mostly needs less iterations and calculation
time. The disadvantage of the Kalman filter is that it needs some
foreknowlegde about the state.
This project demonstrates the use of secure hash functions technique
to implement a file encryption / decryption system.
This implemented application can encrypt / decrypt multiple files
on the fly using a password. The password supplied by the user
is used as the source message from which the hash code (key) is
generated using the SHA algorithm. Then this key is used to
enctypted the data in the file(s). This key is stored in the
encrypted file along with the encrypted data.

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.
simple ATM [Automatic Teller Machine] system the basic functions Login including write-offs, inquiries, deposits, withdrawals and alter the code. Simulation of ATM terminal users logged in, their account numbers and passwords through the ATM network to transmit to the server, ATM database server based on the information to confirm the account number and password is correct, the results back to the ATM terminal. If the correct account number and password, the ATM into the next terminal interface Otherwise prompt mistakes. Cancellation notice for the operation of the server ATM transactions concluded inquiries, deposits, withdrawals and alter the code operations are first sent an order to ATM servers, ATM by the database server implementation of the corresponding operation and operating res
The Bit Array structure provides a compacted arrays of Booleans, with one bit for each Boolean value. A 0 [1] bit corresponds to the Boolean value false [true], respectively. We can look at a stream of bytes as a stream of bits each byte contains 8 bits, so any n bytes hold n*8 bits. And the operation to manipulate this stream or bits array is so easy, jut read or change the bits state or make any Boolean operation on the whole bits array, like 鈥楢ND鈥? 鈥極R鈥? or 鈥榅OR鈥?
