H-based flow control for ATM networks with multiple bottlenecks
(2005)in this paper, the implementation of an H? controller, designed in another work for the flow control in communication networks with a single bottleneck, is considered for asynchronous transfer mode (ATM) networks with ... -
Simultaneous computer control of pH in multiple environmental laboratory bioreactors
(Selper LTD, Publications Div, 2000)This paper describes the design, construction and operation of a computerized pH control system for environmental laboratory reactors. Since pH is often a key environmental parameter in environmental process reactors, it ... -
A path selection based algorithm for maximizing self-satisfiability of requests in real-time Grid applications
(Springer-Verlag Berlin, 2004)Efficient data scheduling in Grid environments is becoming a seemingly important issue for distributed real-time applications that produce and process huge datasets. Thus, in this paper, we consider the data scheduling ... -
Static mapping heuristics for tasks with hard deadlines in real-time heterogeneous systems
(Springer-Verlag Berlin, 2004)Hard real-time tasks are associated with strict deadlines. Classical scheduling heuristics ensure fairness among tasks and prevent deadlock, but are not concerned with deadline compliance. Hence, there is a need for ... -
A comparison of the Common Vector and the discriminative Common Vector methods for face recognition
(2005)The Common Vector (CV) method is a successful method which has been originally proposed for isolated word recognition problems in the case where the number of samples for each class is less than or equal to the dimensionality ... -
Scheduling of a meta-task with QoS requirements in heterogeneous computing systems
(Academic Press Inc Elsevier Science, 2006)Due to the development of new applications and the increasing number of users with diverse needs who are exposed to heterogeneous computing (HQ, providing users with quality of service (QoS) guarantees while executing ... -
A path selection-based algorithm for real-time data staging in Grid applications
(Academic Press Inc Elsevier Science, 2005)Efficient data scheduling is becoming an important issue in distributed real-time applications that produce huge data sets. The Grid environment on which these applications may run seeks to harness the geographically ... -
Frequency domain analysis of model order reduction techniques
(Elsevier Science BV, 2006)In this Study, some popular model order reduction and superelement techniques are studied in frequency and time domains. Frequency domain identification (FDI) methods are also applied to semidiscrete finite element equations ... -
Concurrent scheduling: Efficient heuristics for online large-scale data transfers in distributed real-time environments
(IEEE Computer Soc, 2006)The static staging heuristics proposed in the literature for staging the data items associated with real-time distributed applications adhere to a method by which only one data item is transferred in each communication ... -
2-D analysis and compression of power-quality event data
(IEEE-Inst Electrical Electronics Engineers Inc, 2004)This paper introduces a novel two-dimensional (2-D) representation of the power quality event data. 2-D discrete-time wavelet transform is applied to the 2-D representation of real-life event data. The proposed representation ... -
Case studies on the use of neural networks in eutrophication modeling
(Elsevier Science BV, 2000)Artificial neural networks are becoming more and more common to be used in development of prediction models for complex systems as the theory behind them develops and the processing power of computers increase. A three ... -
On feature extraction for spam e-mail detection
(Springer-Verlag Berlin, 2006)Electronic mail is an important communication method for most computer users. Spam e-mails however consume bandwidth resource, fill-up server storage and are also a waste of time to tackle. The general way to label an ... -
A new approach to mathematical water quality modeling in reservoirs: Neural networks
(Wiley-V C H Verlag GMBH, 1998)Neural Networks are becoming more and more valuable tools for system modeling and function approximation as computing power of microcomputers increase. Modeling of complex ecological systems such as reservoir limnology is ... -
Topological median filters
(IEEE-Inst Electrical Electronics Engineers Inc, 2002)This paper describes the definition and testing of a new type of median filter for images. The topological median filter implements some existing ideas and some new ideas on fuzzy connectedness to improve, over a conventional ... -
Gradient Estimation Using Wide Support Operators
(IEEE-Inst Electrical Electronics Engineers Inc, 2009)One of the fastest methods of localizing edges in images is based on small gradient kernels, such as Sobel, Prewitt, and Roberts. Although small gradient kernels provide a fast way of computing the gradients, they have ... -
An adaptive statistical method for power quality analysis
(IEEE-Inst Electrical Electronics Engineers Inc, 2005)Digital fault recorders installed for monitoring current and/or voltage waveforms acquire and store vast amount of waveform data for post processing. Because of this, effective offline automated event detection from acquired ... -
Segmentation based coding of human face images for retrieval
(Elsevier Science BV, 2004)A coding method for face images by segmenting face regions Such as eyes, mouth, etc. is introduced. Each region is removed from the face image, leaving a smoothly interpolated background which is suitable for efficient ... -
Detection of disturbances in energy system signals using Gaussian distribution fitness test
(IEEE, 2004)In this work., a method based on higher order statistics (HOS) is proposed to detect disturbances in energy system voltage and current waveforms due to faults and various system events. During the normal operation of the ... -
Topological gradient operators for edge detection
(IEEE, 2007)Edge detection in image processing is the task of locating pixel value variations in images. First methods were directional derivative based linear filters. One of the most important problems of these methods that are based ... -
Covariance analysis of voltage waveform signature for power-quality event classification
(IEEE-Inst Electrical Electronics Engineers Inc, 2006)In this paper, covariance behavior of several features (signature identifiers) that are determined from the voltage waveform within a time window for power-quality (PQ) event detection and classification is analyzed. A ...
