As the density of VLSI circuits increases, it becomes attractive to integrate dedicated test logic on a chip. This Built-in Self-Test (BIST) approach not only offers economic benefits but also interesting technical opportunities with respect to hierarchical testing and the reuse of test logic during the application of the circuit. Starting with an overview on test problems, test applications an...

This paper deals with the modelling of plasma discharges induced by electrohydrodynamic actuators. We propose a multi-model method based on fluid conservation equations that allows an increase of the maximum time step imposed by usual explicit schemes. The idea consists in replacing the numerical integration of the plasma equations at the vicinity of the electrodes – where the time step is part...

the impact of price changes (at a level of market) on the other market levels (transfer of prices) will affect welfare of producers, marketing agents as well as consumers. in this study, asymmetric tea market is investigated through an application of johansen co-integration analysis and error correction model (ecm model) to time series of 1976-2009. co integration method used in the import mark...

this paper examines the causal relationship between energy use and real gdp for the period 1967-2002 in iran. the results of phillips- perron test indicate that the real gdp and the four categories of energy, i.e. coal, oil, gas, and hydroelectric energy are integrated of order one. besides, the johansen — juselius maximum likelihood co- integration tests imply the existence of granger causalit...

Automation Systems Engineering Projects typically involve the cooperation of a set of different engineering disciplines and therefore heavily rely on systems integration approaches. However, the configuration of the underlying technical integration platform is a complex and error-prone task requiring high manual effort checking whether the integration of an engineering tool is compatible with a...

Software engineering often no longer involves building systems from scratch, but rather integrating functionality from existing software and components or implementing packaged software. Conventional software engineering comprises a set of influential approaches that are often considered good practice, including structured programming, and collecting a complete set of test cases. However, these...

Maddala and Wu (1999) proposed a simple panel unit test using a Fisher type test. We propose using Percival and Walden (2006) approximate maximum likelihood estimator of the fractional integration order with a Fisher type test to create a simple panel fractional integration order test. By combining the estimator and the test with a wavestrap method to obtain critical values, we allow for cross-...

This article was acceptedfor publication March 1, 1990. The Sensory Integration and Praxis Tests (SIPT) (Ayres, 1989) comprise 17 subtests revised from the Southern California Sensory Integration Tests (SCSIT) (Ayres, 1972) and supplemented with newly designed tests of practic ability. The credentialing process for clinical use of the SIPT is currently administered under the auspices of Sensory...

Manual testing is a time consuming process. In addition, regression testing, because of its repetitive nature, is error-prone, so automation is highly desirable. Robot Framework is simple, yet powerful and easily extensible tool which utilizes the keyword driven testing approach. Easy to use tabular syntax enables creating test cases in a uniform way. Ability to create reusable high-level keywo...
