CA and PKI are crucial parts of many secure network applications. In this paper, we present our effort in the design and implementation of CA/PKI on the PC Windows environment. The Borland C++Builder 5 is used as a software tool to develop client and server software while the Microsoft SQL is used to manage X.509v3 certificates stored at CA. Our CA server is also equipped with a proprietary har...

In this tutorial, you will learn how to fit structural equation models (SEM) using Stata software. SEMs can be in the sem command for standard linear SEMs, gsem generalized or by drawing their path diagrams SEM Builder. After a brief introduction Stata, demonstrated through confirmatory factor analysis model, mediation group analysis, and growth curve random-slope model logistic ordinal regress...

Online Questionnaire Builder (OQB) is web-based survey software that provides complete set of tools for users to conduct the overall survey process from questionnaire design and distribution to the presentation of the survey results. This paper delivers the implementation a comprehensive set of guidelines for the design of online questionnaires via our survey software. The guidelines are drawn ...

This paper proposes an approach and a process to recover traceability links between source code and free text documents in software system developed with extensive use of COTS, middleware, and automatically generated code. The approach relies on a process to filter information gathered from low level artifacts. Information filtering was performed according to a taxonomy of factors affecting tra...

Everyday a huge number of new information resources are linked to the web. This way the web is growing very fast, making search tasks more and more difficult with worse results. To solve the problem several initiatives were undertaken and a new area of research and development emerged: the one called Semantic Web. When we refer to the semantic web we are thinking about a network of concepts. Ea...

An integrated Monte Carlo-Library Least-Squares (MCLLS) System has been developed and implemented to model the complete spectral response of energy-dispersive X-ray fluorescence (EDXRF) spectrometers and perform an inverse elemental analysis by an iterated Library LeastSquares method when an initial guess is provided. This software is a visualization system developed on the Borland C++ Builder ...
