The paper is dedicated to the potential application of the grid technology for the modeling of spatial- temporal wave and wind field characteristics (wave climate modeling). With reference to shipbuilding wave climate knowledge is necessary while ship and engineering offshore construction development and operation. Software complex for wave climate calculations represents a set of physical- mathematical...
A serial-parallel multiplier computes a product by multiplying a parallel input and a serial (or online) input. Serial-parallel multipliers are frequently used in digital communication systems, digital signal processing, on-line computing applications, and embedded computing and communication systems. In this paper, a VLSI-oriented, size-efficient two's complement serial-parallel multiplication architecture...
This paper proposes an adaptive technique in the prediction of dichotomous response variable by combining fuzzy concept with statistical logistic regression. The model was tested on an oral cancer dataset in predicting oral cancer susceptibility. In this paper we will present the development, evaluation and validation of the proposed model based on the experiment carried out. Explanatory power of...
We solve the (2+1)-dimensional Schamel-Kadomtsev- Petviashvili equations with negative and positive dispersion numerically with one or two perturbed plane solitons as initial conditions. In the negative dispersion case, the plane soliton is stable and retains its identity. For the equation with positive dispersion, the plane solitons decay into two- dimensional lump solitons. We show that in contrast...
In pervasive computing environment a number of distributed applications asynchronously exchange data using the event-based mechanism. The OMG defined CORBA Event Service for asynchronous messaging, which provides a flexible channel for asynchronous communication among the distributed and collocated objects. In the existing Event Service channels are created manually by the developers or users to process...
In this paper, the performance scalability in cluster-based video-on-demand (VOD) servers is studied with several grouping configurations of cluster nodes. To find performance bottlenecks of VOD servers, the monitoring functions are employed and the maximum quality of service (QoS) streams are measured under the various requests including VCR functions. From detailed experimental results, a new admission...
The recent advance in wireless network technologies has enabled the streaming media service on the mobile devices such as PDAs and cellular phones. Since the wireless network has low bandwidth channels and mobile devices are actually composed of limited hardware specifications, the transcoding technology is needed to adapt streaming media to the given mobile devices. When large scale mobile clients...
In this paper, we designed a new multicast tree construction mechanism in order to support overlay multicast with scalability and QoS. The architecture we introduce efficiently transmits streaming data to the users from multicast source in an environment in which non-multicast network and multicast network. We have introduced loosely-coupled TCP connection in order to support efficient and reliable...
Internationally organised large-scaled events often cause an overload of the host city's public transportation network as the number of people who use the network increases immensely within a relative small timespan and their flow is concentrated to one direction in the network. To efficiently and individually route participants to the events' location using public transport we would like to provide...
Gene network is a representation for gene interactions. A gene collaborates with other genes in order to function. Past researches have successfully inferred gene network from gene expression microarray data. Gene expression microarray data represent different levels of gene expressions for organisms during biological activity such as cell cycle. A framework for gene network inference is to normalize...
State-of-the-art in digital coding/decoding includes discrete image transformation, quantization, and entropy coding. The key to efficient data compression is associated with image transformation/reconstruction processes. In this paper, we present a different filters wavelet-based intra-frame video coding technique. The wavelet transformation is developed and optimized in order to enhance the visual...
In this paper, we propose data hiding, extraction and handwritten signature authentication algorithms for binary images. Handwritten signature Image can be transmitted from source to target securely over network after processing the source image by using this proposed data hiding algorithm. According to the algorithm, size of the carrier image must be double (or more) the size of source image. If...
Research on testing approaches for different programming paradigms has been done for several years. However, aspect-oriented programming (AOP), a relatively new programming paradigm, has properties that other programming paradigms do not have. These characteristics bring new challenges and issues not present when testing other types of programs such as object oriented programs (OOPs). So this new...
This paper presents a comparison of fuzzy inference methods in intelligent water dispersal controller primarily focuses on grass watering. In irrigation system, measuring and monitoring soil moisture from the soil information and climatologic factors would determine the amount of water for sufficient soil moisture. Mamdani-style and Sugeno-style inference methods have been tested and evaluated using...
