Two digital filtering algorithms for fast estimation of symmetrical components in a power system: A static estimation approach
(
Elsevier
, 2003 , Article)
This paper presents the application of two digital filters working together for fast estimation of power systems symmetrical components. The three-phase unbalanced system is transformed to two phases using α–β-transformation. ...
Modeling and optimization of biogas production from a waste digester using artificial neural network and genetic algorithm
(
Elsevier B.V.
, 2009 , Article)
Artificial neural networks (ANNs) and genetic algorithms (GA) are considered among the latest tools that are used to solve complicated problems that cannot be solved by conventional solutions. The present study utilizes ...
A Property Based Approach for Simultaneous Process and Molecular Design
(
Elsevier B.V.
, 2009 , Article)
In this work, property clustering techniques and group contribution methods are combined to enable simultaneous consideration of process performance requirements and molecular property constraints. Using this methodology, ...
Digitally-tuned resolver converter
(
Elsevier B.V.
, 2009 , Article)
Sinusoidal encoders provide electrical signals related to the sine and cosine of the mechanical shaft angle θ. An analog converter is described for the linearization of these signals and hence for linear computation of θ. ...
Handling data uncertainties in event tree analysis
(
Elsevier B.V.
, 2009 , Article)
Event tree analysis (ETA) is an established risk analysis technique to assess likelihood (in a probabilistic context) of an accident. The objective data available to estimate the likelihood is often missing (or sparse), ...
Factors influencing determination of shale classification indices and their correlation to mechanical properties
(
Springer Verlag
, 2006 , Article)
The influence of sample preparation procedure on the measured classification indices such as clay-size fraction, liquid limit, and plastic limit of shales was investigated. Shale samples covering a wide range of composition ...
Comparative study on the behavior of square foundations resting on confined sand
(
Canadian Science Publishing
, 2009 , Article)
The behavior of shallow foundations resting on laterally and (or) vertically confined sand has been investigated using physical and numerical modeling. The models were designed to simulate the frequently constructed raft ...
Stability analysis and charts for slopes susceptible to translational failure
(
Canadian Science Publishing
, 2006 , Article)
The aim of this paper is to develop two- and three-dimensional stability charts for slopes susceptible to translational failure. An extensive parametric study was conducted using a slope model that is designed to simulate ...
A technique for estimating permeability of a randomly fractured rock mass
(
Springer Verlag
, 2007 , Article)
Extensive field and laboratory testing programs were performed to develop a relationship between the permeability of a fractured limestone and the core recovery values. The studied limestone does not encompass any jointing ...
