Rana, Mukherji; Manishita, Das
In recent years, the development of
application specific instruction set processors (ASIP)
is the exclusive domain of the semiconductor houses
and core vendors. 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).

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.

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.

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
