Metrics on Entities Spaces (p 3)
Adina Florenta GIUCLEA,
Ciprian Costin POPESCU
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
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
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
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
Implementation and Applications of a Three-Round User Strategy for Improved Principal Axis Minimization
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
Laura OBREJA BRASOVEANU,
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
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
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].
Research Integration System (p 97)
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
