Two-step single slope/SAR ADC with error correction for CMOS image sensor
(
Hindawi Publishing Corp
, 2014 , Article)
Conventional two-step ADC for CMOS image sensor requires full resolution noise performance in the first stage single slope ADC, leading to high power consumption and large chip area. This paper presents an 11-bit two-step ...
Hybrid underlay/overlay cognitive radio system with hierarchical modulation in the presence of channel estimation error
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the performance of hybrid cognitive radio (CR) system in the presence of channel estimation error (CER) in terms of bit-error-probability (BEP) and outage probability. We assume simultaneous switching ...
Open and closed-loop motor control system with incipient broken rotor bar fault detection using current signature
(
IEEE
, 2014 , Conference Paper)
Motor drive system is considered the most important asset in industrial applications. Detection of broken rotor bars has long been important but difficult job in detection area of incipient motor faults. The need for highly ...
Trading wireless information and power transfer: Relay selection to minimize the outage probability
(
IEEE
, 2014 , Conference Paper)
This paper studies the outage probability minimization problem for a multiple relay network with energy harvesting constraints. The relays are hybrid nodes used for simultaneous wireless information and power transfer from ...
Pharmacy students' attitudes toward pharmaceutical care in Qatar
(
Dove Medical Press
, 2014 , Article)
Objectives: The study objectives were to investigate Qatar pharmacy students' attitudes toward pharmaceutical care (PC), to identify the factors that influence their attitudes, and to recognize their perceived barriers for ...
The impact of metal inert gas welding on the corrosion and mechanical behavior of AA 6061 T6
(
Electrochemical Science Group
, 2014 , Article)
An attempt has been made to investigate the effects of MIG welding on the corrosion and mechanical properties of AA 6061 T6. A series of experimental techniques has been conducted to evaluate the corrosion and mechanical ...
Hypolithic cyanobacteria colonization of quartz at South Desert
(
Science Publications
, 2014 , Article)
Hypolithic microbial communities (found underneath rocks) were encountered in the southern desert of Qatar where quartz rocks are ubiquitous and are a substrate for hypoliths. These hypoliths thrive where extreme temperature, ...
Studying competitive sorption behavior of methylene blue and malachite green using multivariate calibration
(
Elsevier B.V.
, 2014 , Article)
Sorption of methylene blue MB and malachite green MG (with 96.4% spectral overlap) from bi-solute solution by natural kaolinitic-clay and philipsite-rich-zeolite tuff was addressed where solutes simply quantified using ...
The effects of second language on ethical judgement in accounting
(
Inderscience
, 2014 , Article)
The number of participants in accounting practices and academia who use English as their second language is significant and growing. Many of them are involved in making ethical judgements based on information provided in ...
Release-time aware VM placement
(
IEEE
, 2014 , Conference Paper)
Consolidating virtual machines (VMs) on as few physical machines (PMs) as possible so as to turn into sleep as many PMs as possible can make significant energy savings in cloud centers. Although traditional online bin ...
