This is due to the fact that constructing such architecture is a difficult assignment that needs skilled knowledge in distinct domains: application software development tools, processor hardware implementation, and system integration and verification. To specify the design and implementation of such systems and incorporate the functionality implemented in both hardware and software forms, we are compelled to move on from traditional Hardware Description Languages (HDLs). Since C and C++ are dominant languages used by chip architects, system engineers and software engineers today, we believe that a C++ based approach to hardware modeling is necessary. This will enable codesign, providing a more natural solution to partitioning fuctionality between hardware and software. In this paper, we discuss a design approach of SystemC (a C++ class library) for ASIP at the system-level which provides necessary features for modeling design hierarchy, concurrency and reactivity in hardware. To exemplify and validate the method we employed it to the design of a 32-bit ASIP for Hindi Text-to-Speech Synthesis developed by CEERI, Pilani (INDIA). 2012-01-01T00:00:00Z http://dspace.daffodilvarsity.edu.bd:8080/handle/20.500.11948/705 STUDY OF THE EFFECT OF SODIUM DODECYL SULFATE (SDS) AND ACRIDINE ORANGE ON THE ISOLATION OF PLASMID AND ANTIMICROBIAL RESISTANCE PATTERN OF CLINICAL ISOLATES OF KLEBSIELLA SP Shahriar, Mohammad; Mawla, Shumaila; Bhuiyan, Mohiuddin Ahmed; Hossain, Mahboob For a six months period a total of 25 Klebisiella sp. samples collected from different diagnostic centers were tested for their antimicrobial susceptibility pattern against 16 antimicrobials. All isolates under study showed resistance against cephalexin, cephradine, ciporfloxacin, cloxacillin, erythromycin, oxacillin, rifampicin and tetracycline. Most of the isolates were resistant to amoxicillin (92%), vancomycin (96%), neomycin (84%) and chloramphenicol (76%). Least number of isolates showed resistance to tetracycline (36%), ceftriaxone (40%) and gentamycin (56%), respectively. Out of the 25 isolates, 7 multidrug resistant isolates were selected and they were grown in varying concentrations of Sodium Dodecyl Sulfate (SDS) in Luria broth and their plasmid profile was analysed. Distinct bands of plasmid were observed when the multidrug resistant strains of Klebsiella sp. were grown in 5% SDS and acridine orange (10μg/ml) in Luria broth. On being treated with 5% SDS and 5% SDS along with acridine orange, one isolate (isolate no. 3) developed sensitivity against ceftriaxone, ciprofloxacin, co-trimoxazole, gentamycin and neomycin. 2012-01-01T00:00:00Z http://dspace.daffodilvarsity.edu.bd:8080/handle/20.500.11948/704 STRUCTURAL AND ELECTRICAL PROPERTIES OF SILICON NITRIDE CERAMIC Hasnat, Hosneara A.; Bhuyan, A. H. The effects of structural properties on the d.c. and a.c. electrical properties of different weight gain reaction bonded silicon nitride (RBSN) have been studied in this work. The degree of nitridation is assessed by the ‘weight gain’ of the ceramic, the percentage by which the weight is increased in the nitriding reaction. From X-ray diffraction (XRD) patterns, it is observed that a higher degree of nitradation sample has strong α-silicon nitride peaks. Intensity of α-silicon nitride peaks decreases with decreases weight gain. The higher degrees of nitridation, the samples have less significant Si peak. XRD patterns were recorded to calculate the lattice parameters of RBSN. The lattice parameters for three weight gain RBSN samples are found to be a =b = 7.7727 Å, c= 5.6565 Å (26% weight gain), a=b= 7.6272 Å, c= 5.6374 Å (42% weight gain) and a=b=7.6158 Å, c= 5.7732 Å (58.27% weight gain) and are in good agreement with the reported values from XRD patterns. Porosity (%) and surface morphology was observed by SEM. 2012-01-01T00:00:00Z http://dspace.daffodilvarsity.edu.bd:8080/handle/20.500.11948/703 MESSAGE BASED ANALYSIS ON SIGNALING SYSTEM NUMBER 7 AND ITS COMPARISON WITH MULTIFREQUENCY CODED SIGNALING Md. Shah, Alam; Khan, Mohammad Rezaul Huque A message based comparative study between signaling system #7(SS7) and MFC Signaling is done. Here the limitations of SS7 and MFC signaling are also studied. The reasons for the transition from Multi-frequency Coded (MFC) Signaling to SS7 has been discussed 2012-01-01T00:00:00Z
