Nanofeatures of resorcinol-formaldehyde carbon microspheres
(
Elsevier
, 2012 , Article)
Resorcinol-formaldehyde activated carbon xerogels were synthesized at certain conditions, and their morphology was studied experimentally to examine their detailed nature on the nanoscale level, which has not been reported ...
Generalized Mean Phase Coherence for asynchrony abnormality detection in multichannel newborn EEG
(2012 , Conference Paper)
Inter-hemispheric asynchrony within the multichannel recordings of newborn EEG is associated with abnormal functionality of the newborn brain. Mean Phase Coherence (MPC) as a bivariate phase synchrony measure is widely ...
Performances analysis of SEC based transmit diversity systems with MRC receivers
(
IEEE
, 2012 , Conference Paper)
Switch and Examine combining (SEC) diversity scheme is one of the simplest yet efficient diversity schemes. Earlier in [1] and [2], we proposed sequential power loading algorithm to reduce the average power used at the ...
Modeling security importance and preferences of software services
(
IEEE
, 2012 , Conference Paper)
This paper proposes a modeling framework on how to specify security preferences and importance of software services, and compute a quantifiable value. Our approach advocates for an automatic calculation of the results of ...
Wireless body area sensor networks signal processing and communication framework: Survey on sensing, communication technologies, delivery and feedback
(
Science Publication
, 2012 , Article)
Problem statement: The Wireless Body Area Sensor Networks (WBASNs) is a wireless network used for communication among sensor nodes operating on or inside the human body in order to monitor vital body parameters and movements. ...
إيران والعرب في ظلال الدين والسياسة عبر التاريخ
(
المركز العربي للأبحاث و دراسة السياسات
, 2012 , Book chapter)
تؤدي الجغرافيا دوراً أساسياً في تكوين وعي الأمم بعضها ببعض. ويتعزز دور الجغرافيا عندما تشتبك التجربة التاريخية لأكثر من أمة في مشتركات تحكم الفضاء الثقافي والسياسي والديني لتلك المجتمعات من دون استثناء إيران والعرب من هذه ...
Control of doubly-fed induction machine storage system for constant charging/discharging grid power using artificial neural network
(
IET
, 2012 , Conference Paper)
A large-capacity low-speed flywheel energy storage system based on a doubly-fed induction machine (DFIM) basically consists of a wound-rotor induction machine, and a back-to-back converter for rotor excitation. It has been ...
Signal content estimation based on the short-term time-frequency Rényi entropy of the S-method time-frequency distribution
(2012 , Conference Paper)
A key characteristic of a nonstationary signal, when analyzed in the time-frequency domain, is the signal complexity, quantified as the number of components in the signal. This paper describes a method for the estimation ...
A wavelet-based passive islanding detection technique
(
IEEE
, 2012 , Conference Paper)
Distribution power systems are radial in nature. Power flows in one direction from the utility to the load. Most protection, monitoring, and control devices are designed based on this unidirectional flow of power. Distributed ...
A model to evaluate acquisition price and quantity of used products for remanufacturing
(
Elsevier
, 2012 , Article)
In this paper, an analytical model is proposed to evaluate optimal acquisition price and quantity policy based on the quality of returned used products that are subsequently used for remanufacturing. The model is developed ...
