INTERNATIONAL JOURNAL OF PURE AND APPLIED RESEARCH IN ENGINEERING AND TECHNOLOGY A PATH FOR HORIZING YOUR INNOVATIVE WORK BACK EMF DETECTION METHODS FOR SENSORLESS BRUSHLESS DC MOTOR DRIVES USING MATLAB/SIMULINK
, 2013
"... Abstract Brushless dc (BLDC) motors and their drives are penetrating the market of home appliances, HVAC industry, and automotive applications in recent years because of their high efficiency, silent operation, compact form, reliability, and low maintenance. Traditionally, BLDC motors are commutate ..."

of any external sensors or position detection techniques. In this paper BLDC motor with ideal back-EMF is modelled and simulated in MATLAB / SIMULINK. Simulation model of the controller and BLDC drive are also presented. In order to validate the model various simulation models are studied.
Tagging the Bard: Evaluating the Accuracy of a Modern POS Tagger on Early Modern English Corpora Abstract
"... In this paper we focus on automatic part-of-speech (POS) annotation, in the context of historical English texts. Techniques that were originally developed for modern English have been applied to numerous other languages over recent years. Despite this diversification, it is still almost invariably t ..."

First, using a manually post-edited test set, we evaluate the accuracy of CLAWS when no modifications are made either to its grammatical model or to its lexicon. We then compare this output
Thermodynamic analysis of Spark Ignition engines using the Entropy Generation Minimisation method
"... Abstract: The recent improvement on Spark Ignition Engines has been the result of improved engine thermodynamic cycles, made possible by advances in technologies such as Variable Valve Timing (VVT) and Variable Compression Ratio (VCR). To evaluate the potential of these techniques a thermodynamic an ..."

Integrated Modelling of Vehicle and Driveline Dynamics
"... ABSTRACT In the last years automotive industry has shown a growing interest in exploring the field of vehicle dynamic control, improving handling performances and safety of the vehicle, actuating devices able to optimize the driving torque distribution to the wheels. These techniques are defined as ..."

the integration of a previously developed 14 DOF vehicle model [10] with a powertrain model both developed in Matlab/Simulink environment, in order to obtain a tool ready to be used for the development of control systems. Each vehicle subsystem has been separately modeled and properly interfaced with the others
1Reduced-Dimension Multiuser Detection
"... We present a reduced-dimension multiuser detector (RD-MUD) structure that significantly decreases the number of required correlation branches at the receiver front-end, while still achieving performance similar to that of the conventional matched-filter (MF) bank. RD-MUD exploits the fact that the n ..."

We identify conditions such that error is dominated by active
Seizure Prediction: The Long and the Winding Road,
- Brain,
, 2007
"... The sudden and apparently unpredictable nature of seizures is one of the most disabling aspects of the disease epilepsy. A method capable of predicting the occurrence of seizures from the electroencephalogram (EEG) of epilepsy patients would open new therapeutic possibilities. Since the 1970s inves ..."

PVP2008-61691 ON LEAK DETECTION OF PIPELINES USING COMPUTATIONAL PIPELINE MONITORING
"... ABSTRACT The unintentional release of fluid from pipelines is considered as a leak. Leaks contribute to the environmental pollution, promote corrosion and equipment failures and produce instabilities in the pipeline operation and control. There is a need, therefore, to develop an effective leak dia ..."

The paper also involves computer simulation of pipeline conditions using the developed mathematical model. A leak detection scheme is developed that is based on a computational pipeline monitoring method
Evaluation of Optical Coherence Tomography and Heidelberg Retinal Tomography Parameters in Detecting Early and Moderate Glaucoma
