The development of communications systems demands testing. This paper presents a framework for testing on-the-fly, which relies on the identification of 3 types of tests and on their sequential execution. The ioco conformance relation was adopted in order to assign verdicts. A prototype tool is also presented that supports the proposed framework. This tool, named PROFYT, was developed based on ...

Automated testing of software products has greatly expanded over the past few years. Ever increasing test suites have been developed, along with the computing infrastructure to support them. While the capacity for testing has grown, the environment is not infinitely scalable eventually capital spending is capped. Methodologies need to be explored that improve the overall effectiveness of the te...

The need to better understand whisker growth has dramatically increased as component suppliers convert from tin-lead (SnPb) finishes to Pb-free finishes of Sn and low-alloy-content Sn-based finishes. Whiskers are spontaneous growth of metal filaments emanating from the finish surface. The issues with whiskers are they may grow long enough to cause short circuiting or break off and interfere wit...

Dissolution testing is a core performance test in pharmaceutical development and quality control. Generally, the HPLC method uses the analysis of dissolution testing. In this study, we attempted to improve the dissolution test by using microdialysis methods. We also investigated the comparison of the conventional HPLC dissolution method (batch-sampling method) and the improved dissolution test ...

A test method of methanol content in detergent using a headspace-GC method was established. A 1 g aliquot of test sample was mixed with 0.4 mg of 2-propanol and made up to 20 mL with water. Then, 5 mL of test solution was placed in a headspace vial. The vial was sealed and incubated for 30 min at 60°C, then the headspace gas was analyzed by GC-FID. The recovery from spiked 1 mg/g of methanol wa...

This paper discusses a project carried out at the Digital Laboratories of the Twente University of Technology. The purpose of the project was twofold: Firstly, to develop a digital hardware design and test method. Secondly, to build a hardware interpreter for an intermediate code of Pascal, the so'called P4 code. The implemented P4 machine is based on AM2901 bit slices. During the project a P4 ...

-A Monte Carlo technique was developed suitable for investigating rarefied gas dynamics problems. The procedure is based on the 'test particle' method. The discontinuous function frequently employed for describing the target molecules' velocity distribution is replaced here by a continuous analytic function, the form of which is prescribed prior to the calculations. This modification simplifies...

The overall throughput of automatic test equipment (ATE) is sensitive to the download time of test data. An effective approach to the reduction of the download time is to compress test data before the download. A compression algorithm for test data should meet two requirements: lossless and simple decompression. In this paper, we propose a new test data compression method that aims to fully uti...

Polylactides (PLAs) have been known for several decades but only recently have these polymers gained commercial significance as a leading environmentally benign plastic available from renewable resources. Therefore, it is highly desirable to understand the optical properties of these materials so that they can be manipulated to develop materials of desirable characteristics for a specific objec...
