  • An active radio frequency identification (RFID) system has the advantages of a long identification distance and a good identification rate, overcoming passive RFID drawbacks. Therefore, interest in the development of active RFID systems has been gradually increasing in areas of harbor logistics and national defense. However, some identification failures between active RFID systems developed under the same standards have been reported, presumably due to a lack of development of accurate evaluation methods and test equipment. We present a realization of the hardware and software of an emulator to evaluate the standard conformance of an active RFID system in a fully anechoic chamber. The performance levels of the designed emulator are analyzed using Matlab/Simulink simulations, and the applicability of the emulator is verified by evaluating the standard conformance of a real active RFID tag. Finally, we propose a new evaluation method by incorporating a self-running test mode environment into the RFID tags to reduce testing time and increase testing accuracy. The application of the suggested method to actual tags improves measurement uncertainty by 0.56 dB over that obtained using existing methods.

  • This paper describes a method of AAL(SSCOP) protocol conformance testing and its result analysis in ATM network. Terminal equipment(TE) that implements protocols for connecting ATM network shall be verified if appropriately implement by conformance testing. The protocol specifications and the testing methodology are recommended or standardized by international standardization organization(ITU-T, ISO, etc.). The ATM AAL (SSCOP) protocol which selected for describing conformance test procedure is standardized in ITU-T Q.2110 and ATM Forum UNI 3.1 which are same in contents. Also Testing standard like ATS for SSCOP is specified in ATM Forum 95-1459R2. Construction of conformance testing environment is necessary to coordinate in relations with standards, then testing must beexecuted at that environment and the results from the test system analyzed. For this, it is necessary to select any test case from standard for testing and to make ETS. The ETS is proted on the test system and conformance testing will execute on that system. Finally the result from the test system is to analyze. This conformance testing procedure is applicable to the same other test cases in SSCOP and protocols in any communcation networks.

  • Biometrics is one of promising future technologies within personal identification area, and its application stretches to other variety industry site. Therefore it is necessary to test whether these products are implemented in conformance withe the BioAPI international standard specification. This paper presents the specific construction and application examples of BioAPI v2.0 conformance test suite according to the method described in ISO/IEC 24709. The problems and experience that have been discovered in the construction are described. Three BSP products claiming conformance to BioAPI was tested by proposed the test methodology and tools.

  • Ship STEP is the international standard for the exchange of ship modeling data between heterogeneous systems. It is expected that STEP AP218 can be used for seamless data exchange between various CAD/CAM/CAE systems used in the shipbuilding design process. Although the conformance assessment for standards would maximize the performance and confidence about data exchanges, most research has been directed toward interoperability testing. ISO SC4/TC184 only provides the method for conformance testing, and it can be used with test cases on application protocols. Even though standards have been defined for conformance assessment and testing, there is no organization or association. CAD vendors have focused on interoperability testing for evaluation of the performance of their systems. In this paper, the conformance testing criteria for AP218 have been developed with abstract test cases of ship structures. The requested STEP translator was also reviewed with a developed item pool of testing criteria. The criteria methodology would be a guideline for the development of translators and interfaces. The item pool method of testing criteria for conformance assessment would increase performance and efficiency of data translators for Ship STEP and other standards.

  • The conformance test is a methodology which verifies whether the Implementation Under Test (IUT) conforms to its standard specification or not. In this paper, first, the Conformance Test System(CTS) is implemented in prototype including verification test type, black-box test strategy, conformance test class, remote test structure, and IUT which is described by the ISO Estelle among Formal Description Techniques. Second, through this prototype the proposed system is experimented. The prototype is composed of two modules. The first module is the Estelle-to-Pascal preprocessor which converts the Estelle program to the corresponding Pascal program because the experimental IUT was described using the unexecutable code form of Estelle before being tested by the TD(Test Driver). The TD, the second module, is based on the master-slave concept and plays important role is CTS. The TD acts as the master with the IUTd being the slave. The prototype system is implemented using Turbo-C, Turbo-Pascal and Turbo-Assembly.

  • Conformance testing is to test whether an implementation faithfully meets the requirements of a standard or specification. Above all, it is important to test conformance for XML processors because system errors caused by XML processor without conformance affect badly all related XML based systems. Thus, it is essential to implement XML processors with conformity for the sake of interoperability between XML based systems. In this paper, we survey related works. and describe our method and tool for XML conformance testing. And we show our testing result for Xerces 1.4.4. which is developed as Apache's XML project. as an example.

  • As demands of intelligent urban geospatial information services are increasing in u-Cities, development and use of service standards for the cities are required to make the services interoperable. Conformance tests can be conducted for the standards to implement the services more interoperably and consistently. To improve the interoperability between services, it is necessary to build an evaluation model for services in a perspective of conformance tests. In the context, this study reviews the related references and establishes a conceptual model of the conformance tests for the services and provides an application of the model to a monitoring service for flowing water quantity to prove its usefulness.

  • MPEG-4 visual conformance standard specifies methods to verify whether bitstreams and decoders meet the requirements at the specified profile and level. The test of decoders can be divided into two parts: the static test and the dynamic test. The static test can be performed by examining the decoder output with that of a reference decoder. This paper proposes design methods of test bitstreams for static test of texture decoding, and shows the test results.
