Service-oriented computing advocates the development of new software or services on the basis of existing services. This paradigm shows a great potential of achieving high productivity and low cost, but it faces a challenge in efficiently and correctly using existing services in producing a new application and ensuring its reliability. Building a formal model using a formal specification language...
What is a cloud application precisely? In this paper, we formulate a computing cloud as a kind of graph, a computing resource such as services or intellectual property access rights as an attribute of a graph node, and the use of a resource as a predicate on an edge of the graph. We also propose to model cloud computation semantically as a set of paths in a subgraph of the cloud such that every edge...
In this paper we propose an approach for test data generation using genetic algorithm. Our objective is to design a multi-population genetic algorithm using uniform crossover. In this paper we analyze the performance of proposed uniform crossover multi population genetic algorithm method with different combinations of factors that influence the test data generation strategy. For implementing multi-population...
We propose a model for deterministic distributed function computation by a network of identical and anonymous nodes, with bounded computation and storage capabilities that do not scale with the network size. Our goal is to characterize the class of functions that can be computed within this model. In our main result, we exhibit a class of non-computable functions, and prove that every function outside...
In recent past a number of researchers have proposed strategies for finding test order during Integration testing of object oriented applications while minimizing the cost of stub creation. Some researchers have used graph-based approach while others have suggested solutions using genetic algorithms. This paper presents a survey of various graph-based strategies and genetic algorithm based strategies...
The major weakness of associative classification is examined. A novel approach for classifying imbalanced dataset is proposed. It is an associative classification. Rules which are un-frequent are used to build the classifier rule set. Besides the confidence of pattern ldquoXrarrYrdquo, the confidence of pattern ldquoYrarrXrdquo is used in the approach. Further more, only features of rare classes are...
The probabilistic diagnosis model is useful in many fields such as distributed network, digital system level testing, wafer fault testing. Some topologies and continuous defect units distributions are studied in the previous work. In this paper, we extend the model to arbitrary topology structure with share nodes and to the discrete defect distributions, such as Poission distribution and binomial...
Study on Ion Sensitive Field Effect Transistor (ISFET) based on multi-finger gate design is presented. Mf-ISFET was fabricated by using commercial submicron 1.0 mum CMOS technology and deposited with PECVD Si3N4 as a sensing membrane. The electrical data such as IdVd and IdVg of ISFET are measured to identify the behaviours of ISFET. Furthermore, the evaluation test on ISFET performance such as transient...
Testing and diagnosis techniques play a key role in the advance of semiconductor memory technologies. The challenge of failure detection has attracted investigation on efficient testing and diagnosis algorithm for better fault coverage and diagnostic resolution. March algorithms are widely used in SRAM testing to detect and diagnose SRAM fault model since they are relatively simple and yet providing...
An electrical fault-waveform regenerator (EFWG) is proposed in this paper originally, including its hardware structure and software flow chart. And the EFWG is mainly relying on a power amplifier (PA) to regenerate the electrical fault waveforms recorded by fault recorders (FR), so a digital closed-loop modification technique (DCLMT), which is distinct from the predistortion technique (PDT) widely...
A field test has been made in order to better understand the digital mobile radio channel. At the mobile receiver (450 MHz, 1200 bits/s) recordings were made of the digital signal and the field strength. These recordings were later analyzed by a computer. Some existing models for digital channels have been tested. Theoretically motivated probability density functions for the fading envelope have also...
