Software development organizations are trying to incorporate the concept of software product line to reduce development time and cost. The process of software product line initiation and institutionalization within an organization requires strong relationship of both technical and organizational requirements. In this paper we have identified various cognitive factors that are involved in various activities...
The paper presents a novel discrete search optimization and approach to solve the problem of the hybrid power filter compensator with design a C-type filter and fixed capacitor bank using discrete multi objective particle swarm optimization MOPSO method. This is to ensure both loss reduction and harmonic current mitigation on electrical utility grid. This novel optimization approach, a multi objective...
Last decades, the control and system theory has been beneficed more by the new technological trends. Thus, in numerous (computational) applications, for instant in electronics, in computers, in engineering, as well as, in financial issues, some elements of the control and system theory have been introduced. In this paper, we are interested to change instantly the state of linear matrix differential...
Transport systems play critical role in modern day economies and are prime example of highly dynamic complex systems. Current traffic monitoring systems do not provide timely and granular information which could sufficiently meet system analysis requirements. Simulation augmented with virtual reality (VR) has emerged as an important methodology to model and analyze transport systems. This paper-reports...
The human visual system exhibits reduced sensitivity to distortions in the regions of an image where the rate of change is significant. This entails that a watermark with significant value can be robust and if it resides near around edges and textured areas of an image, it would be imperceptible as well. The present work exploits this characteristic of the human visual system to embed a robust and...
In this paper, we propose a novel method for detection and clustering of defects in ultrasound images based on rosette pattern and image processing techniques. The method employs rosette pattern to extract main features of the image and then according to rosette pattern properties, the extracted samples are mapped to a linear plane. In this step, by the use of image processing techniques, all of the...
This paper explains algorithm of digital image watermarking using DWT for copyright protection.The detail coefficients of second level host image after taking DWT is used as a watermark key for the watermark logo insertion and extraction process. A watermark image recognition system has been developed that uses new class of local image features.These local features of image are invariant to rotation,scaling...
Model validation is essential in modeling and simulation. It ldquofinalizesrdquo the modeling process, and provides the base for reliable experiments with the model, and thus to gain trustworthy insights of the system under study. Diverse techniques have been developed addressing different needs and are used during different phases in the modeling and simulation life cycle. Experimental model validation...
This paper presents a methodology for stochastic deployment of WSN. The methodology uses simulation, statistical analysis, and the Analytical Hierarchy Process to provide an approach that helps decision-makers determine the best deployment strategies based on mission specific goals. The methodology can be used to simplify the decision-making process and provide decision-makers the ability to consider...
The purpose of the paper is to describe a set of variables able to show the level of propensity to innovate. In order to evaluate innovation, the authors built a model with different variables that can help management to measure the level of innovation in their company. The model is based both on theories about innovation and on the authorspsila expertise. A questionnaire was prepared with the aim...
This paper analyses the current technical limitations in the monitoring Web services which mainly focus on the lower layers rather than application layer in TCP/IP stacks. So, the paper puts forward an indicator and model system, proposes some technologies to monitor Web services. The indicators add userspsila behavior and features in comparing with the current technologies, and integrates some services...
Article shows, that separation of traffic and use of appropriate queue management method can be a solution to problem of coexistence of elastic and inelastic traffic. The paper familiarizes with problem of coexistence of different types of traffic, presents two queue management methods and shows simulation results of protocols performance when elastic and inelastic traffic is enqueued into separate...
Mobility is one of the major issues in the performance characterization of wireless communication systems. Wireless communication systems encounter failures. These failures can occur because of software, hardware, human error, or a combination of these factors. The probability of an ongoing call being dropped due to a handoff failure and the probability of a new call being blocked due to the temporary...
Multimedia applications have been the key driving force in converging fixed, mobile and IP networks. A major hurdle in the realisation of this convergence is obtaining Quality of Service from a heterogeneous, best-effort service network. Interactive voice requires strict bounds on delay, jitter and packet losses, video adds significant bandwidth requirements to the network, while Internet only makes...
In the present paper, we present the design and implementation of a 64-bit reduced instruction set (RISC) processor with built-in-self test (BIST) features. A built-in self-test (BIST) or built-in test (BIT) is a mechanism that permits a machine to test itself. Key features of the design including its architecture, datapath, and instruction set are presented. The design is implemented using VHDL and...
This paper presents an integrated modeling, simulation and analysis technique for high-speed serial link transceiver over band-limited channel. The Verilog-A behavioral modeling blocks, transistor-level circuits based on the BSIM models, and the backplane channel with .s4p format model were simulated simultaneously in Cadence Spectre environment. The output data were post-processed with Matlab for...
A keyboard is specially designed and constructed to provide easy typing technology for the visually impaired. There are totally 6 logical sensing switches that are used for acquiring the characters. The whole keyboard works based on Braille system. There are also five other specially used switches like shift (number alphabet toggle button), space, back sense, caps lock and speak. This keyboard is...
In ad hoc and sensor networks, spatial communication constraints have a tremendous influence on many aspects of network performance. The network behavior becomes easily unpredictable with an increasing number of nodes and connections. Therefore, simulation is the evaluation method of choice for ad hoc and sensor networks. Simulations of wireless networks, however, encounter two challenges: First,...
In order to realise the goals of e-health, future e-health systems will require the capability to support patientspsila information management and medical decision making in an open and dynamic ubiquitous medical environment. Such an environment will be knowledge-rich, and sensitive and responsive to the needs of patients, and will allow effective collaborative healthcare service delivery by virtual...
