Design of Low Power and High Speed CMOS Comparator for A/D Converter Application
(Scientific Research Publishing, 2012-04)
This paper presents an improved method for design of CMOS comparator based on a preamplifier-latch circuit driven by a clock. Design is intended to be implemented in Sigma-delta Analog-to-Digital Converter (ADC). The main ...
The effects of astragalus polysaccharide on zebrafish cell apoptosis and senescence
(Scientific Research Publishing, 2012-04)
Astragalus polysaccharide (AP) is the extraction of astragalus, which is a plant used in traditional Chinese herb medicine and may increase an orgainism’s resistance to stress. Several earlier studies in vitro have indicated ...
P2P Model Based on Isolated Broadcast Domains
(Scientific Research Publishing, 2012-04)
Resource location is the most important issue for Peer-to-Peer (P2P) system and flooding is the fundamental mechanism for unstructured P2P systems. Redundant messages will exponential growth with flooding scope increasing ...
Software Defined Radio Prototyping with Visual C++ Express and Code Composer Studio
(Scientific Research Publishing, 2012-04)
The primary goal of this project was educational: to demonstrate Software Defined Radio based prototyping using Visual C++ Express and Code Composer Studio. More specifically an IEEE802.11a Phy [1] compliant baseband ...
The Agricultural Ethics of Biofuels: The Food vs. Fuel Debate
(2012)
Plant-based transportation fuels were the focus of extended criticism in the
press, especially during 2008 when a portion of the blame for a spike in global food prices
was associated with growth of the United States’ ...
An Alternative Use of Horticultural Crops: Stressed Plants as Biofactories of Bioactive Phenolic Compounds
(2012)
Plants subjected to abiotic stresses synthesize secondary metabolites with
potential application in the functional foods, dietary supplements, pharmaceutical,
cosmetics and agrochemical markets. This approach can be ...
Effects of Orbital Motion on the Boundary Layer Flow on a Spinning Disk
(Scientific Research, 2012-12)
The objective of this study is to experimentally examine the effects of orbital motion on the boundary layer flow on a spinning disk. The boundary layer flow on the disk is visualized by the oil flow method, and velocity ...
Controlled Synthesis and Characterization of Nobel Metal Nanoparticles
(Scientific Research, 2012-07)
In this work, monodispersed, well-shaped platinum (3.2 - 6.4 nm), rhodium (2.4 - 5.1 nm), and palladium (3.2 - 5.3 nm)
nanoparticles capped with poly(vinylpyrrolidone) (PVP) were synthesized by a polyol reduction method ...
Molecular Simulation of Ion Transport at the Water/Vapor Interface
(Scientific Research, 2012-08)
Molecular dynamics was used to quantify the role of the size, charge and polarisability of F–
, Cl–
, Br–
, I–
and Na+
ions in
their distribution in the water/vapour interface system. Our results show that the ...
A Novel Technique for Determination of Flow Characteristics of Blast Furnace Slag
(Scientific Research, 2012-06)
A study of flow characteristics of blast furnace slag helps determine its softening and flow (liquid-mobility) temperatures.
The slag with a narrow difference between the two temperatures is termed a “Short Slag”. Its ...
