the growing importance of the environmental and social policies in the spanish savings banksand the large differences between them, take us to delve into those factors that influence on the amounts spent on environment and welfare fund.in this line, we have analyzed all the spanish savings banks, over the period 2004-2008 and using the methodology of panel data, the effect that the composition ...

Presented here is a computational system which uses free−space optical interconnect (FSOI) communication between processing elements to perform distributed calculations. Technologies utilized in the development of this system are integrated two−dimensional Vertical Cavity Surface Emitting Lasers (VCSELs) and MSM−photodetector arrays, custom CMOS ASICs, custom optics, wire−bonded chip−on−board a...

The iPACE-V1 (Image Processing Adaptive Computing Engine) is a portable, reconfigurable hardware platform, designed for real time, in-field image processing applications. IPACE-V1 has ample memory and the capability of full or partial reconfiguration without the need of a host computer. This paper describes the architecture of the hardware board along with the software design environment. We sh...

This paper describes a real time system for human computer interaction through gesture recognition and three-dimensional hand tracking. We use one camera that is focused at the user's hand, with an attached small rigid dark square. The system can recognize in real time the gesture and track the hand in three dimensions. The system uses a SIMD real time image processing board for low and interme...

A description of the signal processing stage of an on-board integrated VLSI multi-carrier demodulator at the demultiplexing level is presented in this paper, along with a description of the optimization procedure that has been developed for the signal processing functions. The varying adjacent carrier interference and channel noise distribution are modeled to provide the best performing demulti...

A high-performance Karhunen-Loève transform for multi-spectral imagery suitable for remote-sensing applications has been prototyped on a platform FPGA, by means of a PC-based development board. Performance estimates suggest that the design will already outperform implementation on a high-end microprocessor, given due attention to I/O (Input/Output). General conclusions are reached for the utili...

Computer grading of hardwood lumber promises to avoid regrading of the same lumber because of disagreements between the buyer and the seller. However, the first generation of computer programs for hardwood lumber grading simplify the process by modeling defects on the board as rectangles. This speeds up the grading process but can inadvertently put a board into a lower grade because rectangular...

Why Image Compression in Space ? Images acquired on board spacecrafts (earth observation satellites, scientific probes...) represent in most cases very large volumes of data. It is then necessary to store these data on board (during non visilibility period) and to transmit them to ground. Due to the stringent limitations (in terms of mass, power and cost) which apply to on board equipements, it...

We introduce a speech processing system that uses a low-cost PC board to be plugged into an 8 bit ISA bus expansion slot. The board is based on the AT&T's DSP32C signal processor. The advantage of this configuration is that we can execute many different applications by downloading them from the PC, all running on the same hardware. The software applications for this system include: Rehabilitati...
