This paper presents a powerful and flexible Digital Signal Processing (DSP) architecture based on the Texas Instruments TMS320VC33 DSP and high speed PCI bus. The DSP board provides a convenient, flexible means to test signal processing algorithms in real-time hardware. Algorithms implemented for several research projects include Normalized Least Mean Square (NLMS) Adaptive Filter, Recurrent Ne...

We analyze the relations between the stock market and a stock bulletin board system (BBS) in Japan. Previous studies in the USA found that the characteristics of messages posted on stock BBSs can predict market volatility and trading volume. We develop hypotheses based on the results of those analyses and apply statistical analysis to the data about companies mentioned in a large number of mess...

This paper presents an active vision system for realtime traffic sign recognition. The system is composed of two cameras, one is equipped with a wide-angle lens and the other with a telephoto lens, and a PC with an image processing board. The system first detects candidates for traffic signs in the wide-angle image using color, intensity, and shape information. For each candidate, the telephoto...

At Texas Instruments, integrated circuits in production are continually becoming more power efficient and faster. The time associated with testing these designs, say with a with Taradyne test platform, represents a large cost of the overall price of these integrated circuits. This paper discusses the design and layout of a compact mixed signal printed circuit board using a digital signal proces...

The proliferation and easy access to a new breed of ARMbased single-board computers has promoted an increased usage of these platforms in the creation of self-contained Digital Music Instruments. These directly incorporate all of the necessary processing power for tasks such as sensor signal acquisition, control data processing and audio synthesis. They can also run full Linux operating systems...

Absmacr-The Next-Generation Precipitation Radar (PR-2) prototyped by NASNJPL will depend heavily on high-performance digital processing to collect meaningful rain echo data. Using fieldprogrammable gate arrays (FPGAs), we have developed for the PR-2 a pulse-compression processor and adaptive timing controller that will enable full on-board processing capabilities in a 14 and 36 GHz spacebome ra...

conclusions the layout of whiteboard in classrooms can be effective in causing student’s neck pain. in this study, the suitable height of installation of whiteboard was determined and it is recommended to be used in classrooms. background the mismatch between equipments and anthropometric dimensions of users is one of the issues that can be effective on development of musculoskeletal disorders ...

particle size, board density and adhesive content are the most important factors, influencing on physical and mechanical properties of particleboard. in this study the effects of density, adhesive content and particle size on withdrawal strength of particleboard made from populus (populus alba) particles have been studied. three levels of density including 0.65, 0.7, and 0.75 g/cm3, three level...
