This
paper presents a new adaptive mobility-aware MAC protocol
for sensor networks (MS-MAC). The protocol uses any change
in received signal level as an indication of mobility and, when
necessary, triggers the mobility handling mechanism. By doing
this way, the new mobility-aware MAC protocol can work very
energy-efficiently when the network is stationary, whereas it can
maintain some level of network performance when there are
mobile sensors.

The GNU Scientific Library (GSL) is a collection of routines for numerical computing. The routines have been written from scratch in C, and present a modern Applications Programming Interface (API) for C programmers, allowing wrappers to be written for very high level
The 6.0 release of Visual C++ shows Microsoft s continued focus on Internet technologies and COM, which are key components of the new Windows Distributed interNet Application Architecture (DNA). In addition to supporting these platform initiatives, Visual C++ 6.0 also adds an amazing number of productivity-boosting features such as Edit And Continue, IntelliSense, AutoComplete, and code tips. These features take Visual C++ to a new level. We have tried to make sure that this book keeps you up to speed on the latest technologies being introduced into Visual C++.
The running time of quicksort can be improved in practice by taking advantage of the fast
running time of insertion sort when its input is “nearly” sorted. When quicksort is called on a
subarray with fewer than k elements, let it simply return without sorting the subarray. After the
top-level call to quicksort returns, run insertion sort on the entire array to finish the sorting process.

Features a unique program to estimate the power spectral density. The spectrum containing all significant details is calculated from a time series model. Model type as well as model order are determined automatically from the data, using statistical criteria. Robust estimation algorithms and order selection criteria are used to obtain reliable results. Unlike in FFT analysis, where the experimenter has to set the amount of smoothing of the raw FFT, the right level of detail is assessed using the data only.
These codes require an ASCII input file interp.dat of the following form:
N: Number of Polynomial Interpolation Points (Small)
First Sample (x1,y1)
Second Sample (x2,y2)
...
Nth Sample (xN,yN)
N1: Number of Error Evaluation Points (Large)
First Sample (x1,y1)
Second Sample (x2,y2)
...
N1th Sample (xN1,yN1)
PixelFusion.dsp
This file (the project file) contains information at the project level and
is used to build a single project or subproject. Other users can share the
project (.dsp) file, but they should export the makefiles locally.
PixelFusion.h
This is the main header file for the application. It includes other
project specific headers (including Resource.h) and declares the
CPixelFusionApp application class.
PixelFusion.cpp
This is the main application source file that contains the application
class CPixelFusionApp.
PixelFusion.rc
This is a listing of all of the Microsoft Windows resources that the
program uses. It includes the icons, bitmaps, and cursors that are stored
in the RES subdirectory. This file can be directly edited in Microsoft
Visual C++.
PixelFusion.clw
This file contains information used by ClassWizard to edit existing
classes or add new classes. ClassWizard also uses this file to store
information needed to create and edit message maps and dialog data
maps and to create prototype member functions.
