The Kalman filter is a set of mathematical equations that provides an efficient computational
[recursive] means to estimate the state of a process, in a way that minimizes
the mean of the squared error. The filter is very powerful in several aspects:
it supports estimations of past, present, and even future states, and it can do so even
when the precise nature of the modeled system is unknown.
This paper shows the development of a 1024-point
radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA technologies. The developed core is targeted into a Xilinx廬 Spartan鈩?3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit data acquisition system for performance evaluation purposes. several tests were performed in order to verify FFT core functionality, besides the time performance analysis highlights the core advantages over commercially available DSPs and Pentium-based PCs. The core is compared with similar third party IP cores targeting resourceful FPGA technologies. The novelty of this work is to provide a lowcost, resource efficient core for spectrum analysis
applications.
Fortran has always been the principal language used in the fields of scientific,
numerical, and engineering programming, and a series of revisions to the standard
defining successive versions of the language has progressively enhanced its power
and kept it competitive with several generations of rivals.
Beginning in 1978, the technical committee responsible for the development
of Fortran standards, X3J3 (now called J3), laboured to produce a new, much-
needed modern version of the language, Fortran 90. Its purpose is to "promote
portability, reliability, maintainability, and efficient execution... on a variety of
computing systems". The standard was published in 1991, and work began in
1993 on a minor revision, known informally as Fortran 95. Now this revised

several CD commands can report addresses either in logical block address or in MSF format (see Table 1).
The READ HEADER, READ SUB-CHANNEL, and READ TOC/PMA/ATIP commands have this Feature
The advantages of automation can be exploited in order to solve or to
minimize the needs of manual approach. In order to support the development of
survey accurate cadastral system, an automatic programming approach will be
adopted. Database selection system will conduct several outliers integrity
checking, rebuild cadastral spatial topology (cadastral lot) and make selfcorrection
procedures based on cadastral survey concepts and mathematical
model respective to the cadastral lots selected. This is to ensure that all cadastral
lots are kept in a closed polygon and provide accurate and "clean" cadastral
information.. This system was developed in windows environment.
C++ by Dissection presents a thorough introduction to the programming process by
carefully developing working programs to illuminate key features of the C++ programming
language. Program code is explained in an easy-to-follow, careful manner throughout.
The code has been tested on several platforms and is found on the bundled CDrom
accompanying this text. The code in C++ By Dissection can be used with most C++
systems, including those found in operating systems such as MacOS, MS-DOS, OS/2,
UNIX, and Windows.
Software-defined radios (SDRs) have been around for more than a decade. The
first complete Global Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions.We therefore find it timely to publish an up-to-date text on the subject
and at the same time include Galileo, the forthcoming European satellitebased
navigation system. Both GPS and Galileo belong to the category of Global
Navigation Satellite Systems (GNSS).
C++ is widely used in the software industry. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. several groups provide both free and proprietary C++ compiler software, including the GNU Project, Microsoft, Intel, Borland and others.
During the past four years, most of our research activities have been focused on image but also video
and 3-D objects processing for security applications (watermarking and biometrics) and communications
(talking heads, interfaces), with a special emphasis on facial images. More about our work can be found
at http://www.eurecom.fr/~image.
Our research activities are conducted with the backing of several industrials, in particular France
Telecom Research and STMicroelectronics.
For the past few years, we have had a regular scientific collaboration on Fractal Image Coding,
Watermarking and Biometrics with the University of California, Santa Barbara (UCSB), in particular with
