Database Service Provider (DSP) is a provider in the Internet that provides service in maintaining data so users can access their data anytime and anywhere from the Internet. DSP model introduces several challenges. An important issue is data confidentiality. In this paper we propose a Usage Control (UCON) model and architecture that can be enforced to support data confidentiality in DSP model....

DSP software development has been tied down by extreme computational requirements. Furthermore, the DSP development tools available today are less advanced than in other embedded software design. This has lead to DSP software architectures that have not taken into account future expansion needs. Therefore, DSP software architectures have been inherently closed. Now, as system complexity increas...

Arizona State University (ASU) has developed an on-line DSP laboratory that is based on an object-oriented Java tool called Java Digital Signal Processing (J-DSP). J-DSP is currently being used in a senior-level DSP course at ASU. J-DSP has a rich suite of signal processing functions that facilitate interactive on-line simulations of modern statistical signal and spectral analysis algorithms, f...

In this paper we have proposed the design of a DSP microcontroller where the processor load is significantly reduced by relegating the math-intensive DSP algorithm to dedicated transform computing modules. It is shown that the use of such transform modules will facilitate scalability, reusability and flexibility for implementation of wide varieties of DSP functionalities. Moreover, it would be ...

San Antonio building blocks of DSP change? Questions such as these will remain topical into the foreseeable future as progress in DSP techniques and architectures continues to transform the state of the art. DSP applications, in fact, drive integrated circuit technology in several important areas: architectures for special-purpose digital signal processors, high-speed data conversion devices, a...

Dentin sialoprotein (DSP), a 53 kDa glycoprotein, is believed to be present exclusively in dentin. Using rat and mouse digoxigenin labeled (DIG)-DSP and 35S-DSP riboprobes, and in situ hybridization techniques, we have studied the presence of DSP mRNA at specific developmental stages of dentinogenesis. In mouse and rat molars and incisors, DSP transcripts were localized in young odontoblasts as...

Diarrhetic shellfish poisoning (DSP) is a severe gastrointestinal illness caused by consumption of shellfish contaminated with DSP toxins that are originally produced by toxic dinoflagellates. Based on their structures, DSP toxins were initially classified into three groups, okadaic acid (OA)/dinophysistoxin (DTX) analogues, pectenotoxins (PTXs), and yessotoxins (YTXs). Because PTXs and YTXs ha...

Recently there are greater advances in bioinformatics and genomic signal processing. Digital Signal Processing (DSP) applications in genomic sequence analysis have received great attention in recent years. New methods are being developed to analyze Deoxyribonucleic acid (DNA) sequences. In order to use DSP principles to analyze DNA sequences, the DNA sequences should be converted into numeric s...

1. INTRODUCTION Rice University has a decades-long tradition of both digital signal processing (DSP) research and education, beginning in 1968. Since that time, Rice University has become a world leader and continued to be a pioneer in the DSP field. This paper will focus on the following three areas of activity at Rice. First, a brief history of DSP education and research at Rice will be prese...

(-)15-Deoxyspergualin (DSP), a bacterial metabolite obtained from Bacillus laterosporus, was shown to effectively suppress autoantibody production in mice and alloimmune reaction in mice and rats. Its potential toxicity and safety margin in BALB/c mice were studied by administering the drug, 0.5-5.0 mg/kg body weight, s.c., 6 days/week for 3 months. The animals were weighted every two weeks, an...
