Abstract: CNFET has emerged as an alternative material to
silicon for high performance, high stability and low power SRAM
design in recent years. SRAM functions as cache memory in
computers and many portable devices. In this paper, a new SRAM
cell design based on CNFET technology is proposed. The proposed
SRAM cell design for CNFET is compared with SRAM cell designs
implemented with the conventional CMOS and FinFET in terms of
speed, power consumption, stability, and leakage current. The
HSPICE simulation and analysis show that the dynamic power
consumption of the proposed 8T CNFET SRAM cell’s is reduced
about 48% and the SNM is widened up to 56% compared to the
conventional CMOS SRAM structure at the expense of 2% leakage
power and 3% write delay increase.
Abstract: The semiconductor industry is placing an increased
emphasis on emerging materials and devices that may provide
improved performance, or provide novel functionality for devices.
Recently, graphene, as a true two-dimensional carbon material, has
shown fascinating applications in electronics. In this paper detailed
discussions are introduced for possible applications of grapheme
Transistor in RF and digital devices.
Abstract: Land shortage for burials is one of many issues that emerge out of accelerated urban growth in most developing Asian cities, including Kuala Lumpur. Despite actions taken by the federal government and local authorities in addressing this issue, there is no strategic solution being formulated. Apart from making provisions for land to be developed as new cemeteries, the future plan is merely to allocate reserve land to accommodate the increasing demands of burial grounds around the city. This paper examines problems that arise from the traditional practices of Malay funerary as well as an insight to current urban practices in managing Muslim burial spaces around Kuala Lumpur metropolitan region. This paper will also provide some solutions through design approach that can be applied to counter the existing issues.
Abstract: This research proposes an algorithm for the simulation
of time-periodic unsteady problems via the solution unsteady Euler
and Navier-Stokes equations. This algorithm which is called Time
Spectral method uses a Fourier representation in time and hence
solve for the periodic state directly without resolving transients
(which consume most of the resources in a time-accurate scheme).
Mathematical tools used here are discrete Fourier transformations. It
has shown tremendous potential for reducing the computational cost
compared to conventional time-accurate methods, by enforcing
periodicity and using Fourier representation in time, leading to
spectral accuracy. The accuracy and efficiency of this technique is
verified by Euler and Navier-Stokes calculations for pitching airfoils.
Because of flow turbulence nature, Baldwin-Lomax turbulence
model has been used at viscous flow analysis. The results presented
by the Time Spectral method are compared with experimental data. It
has shown tremendous potential for reducing the computational cost
compared to the conventional time-accurate methods, by enforcing
periodicity and using Fourier representation in time, leading to
spectral accuracy, because results verify the small number of time
intervals per pitching cycle required to capture the flow physics.
Abstract: In this research relationship between to be smooth the
interest and output of accepted companies stock at negotiable paper
exchange of Tehran is studied. Static community capacity included
363 companies member of negotiable paper exchange of Tehran that
54 companies were, by considering research limitation, selected from
2004 to 2009. Needed data for model test in librarian method was
chosen from RAH AVARDE NOVIN informative banks, TADBIR
and collecting needed data was selected from Tehran negotiable
paper exchange archive. Given results show that in spite of belief
among people based on companies have more smooth interest have
more output, but resulted outcomes of test-done reveals that there is
no relation between smooth interest and stock output.
