Metrics on Entities Spaces (p 3)
Adina Florenta GIUCLEA, Ciprian Costin POPESCU Marius GIUCLEA

In this work, we deal with concept of “metric”. At first, we briefly discuss some issues regarding this very shaded notion in human knowledge. Second, we emphasize its usefulness in Mathematics, particularly in the relatively recent field of fuzzy models.

Hypertext Entities’ Semantic Web-Oriented Reengineering (p 9)
Cosmin TOMOZEI

This paper’s aim is to define the concept of Hypertext Semantic Web-Oriented Reengineering (HSR) as a process of distributed applications development which takes into consideration the semantic aspect in information retrieval and communication. It is virtually possible to apply the reengineering on web applications concerned being about the efficiency of the ideas of data structures and implementation than to mainly being troubled with the language or syntactic point of view. This research also brings some examples of distributed applications types, some small segments of them being mainly explained as well, in order to make our theory strongly connected with the practical work from software companies. It is very important that semantic approaches to be implemented while developing software applications, mostly when reengineering is integrated in the development process, as a step for the evolution to the next generation of web.

C# Entities Quality Analysis (p 20)
Ion IVAN Daniel MILODIN Sorin-Nicolae DUMITRU Dragos PALAGHITA

In this paper we will presents the requirements for C# batch program development. Also there is constituted a quality analysis system of indicators for C# programs. The software structure used to analyze the C# program batch and computation of regarded indicators is presented. C# program classes are constructed and the appurtenance criterion of a C# program to a particular class is established through an aggregation process.

Some Notes on the Logistic Distribution (p 32)
Alexandru ISAIC-MANIU, Viorel Gh. VODA

In this paper we study some properties of the density function which may be obtained from the distribution of the last order statistic from a reduced logistic population. Its truncated variant is also discussed. The point and interval estimations for θ are provided also. The so-called (P, γ) - type statistical tolerances are constructed and a comment on the hazard rate is done also. The last paragraph is devoted to testing procedures on the parameter involved.

Implementation and Applications of a Three-Round User Strategy for Improved Principal Axis Minimization (p 44)
Ali ÜNLÜ, Michael D. KICKMEIER-RUST

This paper presents a three-round user strategy (EPM), extending the C implementation of Brent’s PRAXIS algorithm by Gegenfurtner. In a first round, EPM applies a multistart procedure for global optimization, randomly generating and evaluating multiple sets of start values drawn from weighted primary and secondary intervals. Using the parameter estimates of the smallest first round minimum, in a second and third round, EPM performs iterative minimization runs and applies an additional break-off criterion to improve and stabilize the approximated minimum and parameter estimates. Moreover, EPM increases the precision of the original PRAXIS implementation by a conversion from the double to the long double data type. This conversion is not trivial and even seen to be essential for minimizing a complex empirical function from psychometrics. Important special cases of EPM are discussed and promising strategies for the handling of EPM are proposed. EPM’s advantages over PRAXIS are illustrated using two different functions: a ‘well-behaved’ Rosenbrock function and an ‘illbehaved’ psychometric likelihood function.

Correlations Between Capital Market Development and Economic Growth: the Case of Romania (p 64)
Laura OBREJA BRASOVEANU, Victor DRAGOTA, Delia CATARAMA, Andreea SEMENESCU

In the literature on endogenous growth, the link between capital markets development and economic growth has received much attention. Although there are many studies regarding this aspect, approaches on emergent ex-communist countries’ economies, especially for Romania, are very few comparatively to the general cases. Our paper examines the correlation between capital market development and economic growth in Romania using a regression function and VAR models. The results show that the capital market development is positively correlated with economic growth, with feed-back effect, but the strongest link is from economic growth to capital market, suggesting that financial development follows economic growth, economic growth determining financial institutions to change and develop.

Issues and Procedures in Adopting Structural Equation Modeling Technique (p 76)
Siu Loon HOE

When applying structural equation modeling (SEM) technique for analytical procedures, various issues are involved. These issues may concern sample size, overall fit indices and approach. Initiates of SEM may find it somewhat daunting in resolving these technical issues. The purpose of this paper is to highlight key issues in adopting SEM technique and various approaches available. This paper provides a discussion on the sample size, fit indices, standardized paths, unidimensionality test and various approaches in relation to SEM. It is hoped that having reviewed the paper, new researchers can devote more time to data analysis instead of procedural issues involved.



Comments on Software


Adaptable Software Shells Versus Microsoft Software Shells (p 84)
Dumitru TODOROI

Development and evolution of Microsoft Office and Microsoft Windows shells is based in general on the special methodology of Software creation and implementation such as macros, subroutine, custom commands and specialized features; this methodology of Microsoft Software shells is analyzed. The universal methodology of Adaptable Software creation is proposed. Present result evaluates from [Tod-08.1]2 which is a evolution of the Fulbright research project nr. 22131 “Societal Information Systems’ Adaptable Tools “ performed in the University of Omaha at Nebraska, USA in the 1997/1998 academic year [Tod-98].

Academic Research Integration System (p 97)
Iulia SURUGIU, Manole VELICANU

This paper comprises results concluding the research activity done so far regarding enhanced web services and system integration. The objective of the paper is to define the software architecture for a coherent framework and methodology for enhancing existing web services into an integrated system. This document presents the research work that has been done so far in this aspect by applying the proposed architecture for system integration in the academic field. The basics concepts used are Enterprise Application Integration (EAI) and Service Oriented Architecture (SOA), as the most commonly used approaches to information systems integration lately. SOA is an Information Technology (IT) architectural style that supports the transformation of businesses into a set of linked services, or repeatable business tasks that can be accessed when needed over a network. This may be a local network, it may be the Internet, or it may be geographically and technologically diverse, combining services in New York, Paris, and Beijing as though they were all installed on a local desktop. These services can coalesce to accomplish a specific business task, enabling businesses to adapt quickly to changing conditions and requirements.
