USER PERCEPTION FOR BIOMETRICS AND SECRET MANAGEMENT
This paper aims to present a view of some problems that users face with PINs and how they manage them. Furthermore, we aimed to explore effects of their PIN management techniques on judging PIN problems. The research questions were (1) Do users manage their PINs in a secure way? Are they aware of PIN problems? And (2) what are the perceptions of users surrounding the use of a biometrics authentication system? A survey instrument to test on Yemenis was carried out. Results show they do not suffer from the well-known problem which is forgetting PINs. Authors believe that due to the cultural behaviour men do not share credit cards or PINs with their partners. Moreover, in that culture they depend on cash payment and rarely use credit cards or websites for e-payment. Based on Rashed and Santos results, our study recommends using biometrics and PIN s in ATM. Index Terms - Technology Acceptance, TAM, Intension to use, Biometrics, Arab Culture.
COMMUNICATION NETWORK FOR DISTRIBUTION RESOURCES IN MODERN AUTOMATION
The principle goal of this project is to develop DER object models that are of suitable quality to be submitted to the IEC for eventual standardization. This quality can only be obtained by validating the object models using the expertise of vendors, utilities, DER owners, and other DER stakeholders. Utility companies have been battling with the coordination of datas as a two way communications and thus have to be faced with controlling increasing amounts of DER within their utility distribution systems, thus requiring application of more automation system to confront and administer/manage the challenges and opportunities faced by DER. Of particular interest is the advance distributed automation (ADA) that will incorporate DER to automated management of distribution network. Our algorithms respond to system contingencies in the electric grid, visualize the grid behavior for the benefit of reliability operators, and simulate in a hybrid setting integrated continuous system behavior.

Traceability was conceived as a possible solution for one of the main problems in the software development process: conformity assurance between software artifacts and their requisites. In the field of Model Driven Engineering (MDE) "traces", traceability links between the artifacts, register a link between a group of input model elements and a group of output model elements. Such link is related to the model transformation specification that associates those groups. Under this view, a number of researches have investigated a way to correctly explore traceability, so as to improve the MDE process quality. This article presents a review on traceability through model-driven approaches as well as an analysis on the support provided by the Atlas Transformation Language (ATL). Several limitations related to ATL’s traceability data recovery were identified and possible solutions were proposed. Index Terms - traceability, model transformation, model driven development, Atlas Transformation Language.
UMA ABORDAGEM PARA GERAÇÃO DE PROCEDIMENTOS DE TESTE BASEADA EM ESPECIFICAÇÃ•ES UMIL E OCL
In most software development endeavors, testing is an important quality control technique. The main purpose of software testing is to reveal software failures. Functional testing is a type of testing where test cases are derived from the functional specification of the software under test. There-fore, the effectiveness of the test is directly related to the quality of the specification. A common category of software systems is the CRUD systems. CRUD systems are systems based on features like create, retrieve, update, and delete. This paper presents an approach for CRUD systems specifi-cation-based testing. This approach uses a technique to specify CRUD systems using UML class models enriched with Object Constraint Language (OCL) constraints and another technique to generate platform independent test procedures from the specification. These test procedures can be transformed into platform specific test procedures that can be used to verify the implementation of CRUD systems. Index Terms - CRUD, OCL, software testing, UML.
