Information system for administrating and distributing
color images through internet
Abstract: The information system for administrating and distributing color images through the Internet ensures the consistent replication of color images, their storage - in an on-line data base – and predictable distribution, by means of a digitally distributed flow, based on Windows platform and POD (Print On Demand) technology. The consistent replication of color images inde-pendently from the parameters of the processing equipment and from the features of the pro-grams composing the technological flow, is ensured by the standard color management sys-tem defined by ICC (International Color Consortium), which is integrated by the Windows operation system and by the POD technology. The latter minimize the noticeable differences between the colors captured, displayed or printed by various replication equipments and/or edited by various graphical applications. The system integrated web application ensures the uploading of the color images in an on-line database and their administration and distribution among the users via the Internet. For the preservation of the data expressed by the color im-ages during their transfer along a digitally distributed flow, the software application includes an original tool ensuring the accurate replication of colors on computer displays or when printing them by means of various color printers or presses. For development and use, this application employs a hardware platform based on PC support and a competitive software platform, based on: the Windows operation system, the .NET. development medium and the C# programming language. This information system is beneficial for creators and users of color images, the success of the printed or on-line (Internet) publications depending on the sizeable, predictable and accurate replication of colors employed for the visual expression of information in every activity fields of the modern society. The herein introduced information system enables all interested persons to access the information from the on-line database, whenever they want, wherever they are, by means of the digital infrastructure, computer net-works and modern communication technologies.

Abstract: There are defined level of orthogonality for text entities. There are built orthogonal entities. There are identified operations on orthogonal entities and for each operation there are speci-fied the proprieties and the signification from applicability point of view. There is described software use to implement operations with structured entities.
Informational trends for organizations in information society
Abstract: Companies have always been very carefully managed money, raw materials, machines and human resources. Today, they recognize the growing importance of the fifth big resource: in-formation. They have finally understood that the within the global market with increased competition, using modern methods for planning, coordination and control, a company can-not function without acknowledging information and communications technology progress.
Using Electronic Systems for Document Management in Economic Entities
Abstract: Document workflow and management, be them scanned documents, computer-generated e-documents or complex file formats, are critical elements for the success of an organization. Delivering the correct information to the right person, at the right moment is a fundamental element of daily activity. In the Internet era, documents have a new format; and what is more important: completely new functions. Paper is replaced by electronic formats such as .html, .xms, .pdf or .doc. The price for this progress is the increasing technological complexity, and with this complexity comes the need for more efficient techniques of management and organi-zation such as a document management electronic system. This paper aims to present docu-ment management not as a separate software category on the IT market, but as an element in-tegrated with any software solution, maximizing its capacity of making business more effi-cient.
Integrated Administration of the Organizations Informational Resources
Abstract: Organizations grow and develop continuosly and information volume grows in the same rythm, which makes from improvement or changing the old counting systems an imperative. More and more companies, instead of continuing to invest in small applications choose integrated informa-tional solutions, which are adapted to the user’s daily needsfrom, all decisional levels. Although apparently profitable from the costs point of view, small applications assure only the simple eco-nomical solutions between clients, partners, furnisors, and employees. For high business volume companies, this kind of applications become useless in a short time, fact that involves extra sus-tained investitions.
The Viral Concept: the Winning Ticket of the Romanian
Online Advertising Industry
Abstract: The connection between the steady development of the Internet in Romania in the last five years, as channel of transmitting the marketing message, and the viral concept, as method of transmitting the message, may become the winning ticket for the Romanian online advertising market. Thus, in the current socio-economic context, any company who wishes to be success-ful in the virtual space cannot ignore the viral marketing techniques for several reasons. Firstly, we are talking about the profile of Internet users who tend to constitute a new social group. Secondly, we are talking about the thirst for information. And, last but not least, we are talking about the appetite for online chatting, statistics showing that 62% of the Roma-nian Internet users consider it a very “savory” information channel.
Application of the Scaling Functions to Nonparametric Regression
Abstract: For estimating regression function we can use many proceedings. In this paper, we have cho-sen to apply scaling functions to the estimation of regression functions.
About Hierarchical Xml Structures, Replacement of Relational Data
Structures in Construction and Implementation of Erp Systems
Abstract: The projects essential objective is to develop a new ERP system, of homogeneous nature, based on XML structures, as a possible replacement for classic ERP systems. The criteria that guide the objective definition are modularity, portability and Web connectivity. This objective is connected to a series of secondary objectives, considering that the technological approach will be filtered through the economic, social and legislative environment for a validation-by-context study. Statistics and cybernetics are to be used for simulation purposes. The homogeneous approach is meant to provide strong modularity and portability, in relation with the n-tier principles, but the main advantage of the model is its opening to the semantic Web, based on a Small enterprise ontology defined with XML-driven languages. Shockwave solutions will be used for implementing client-oriented hypermedia elements and an XML Gate will be de-fined between black box modules, for a clear separation with obvious advantages. Security and the XMLTP project will be an important issue for XML transfers due to the conflict be-tween the open architecture of the Web, the readability of XML data and the privacy elements which have to be preserved within a business environment. The projects finality is oriented on small business but the semantic Web perspective and the surprising new conflict between hi-erarchical/network data structures and relational ones will certainly widen its scope. The proposed model is meant to fulfil the IT compatibility requirements of the European environ-ment, defined as a knowledge society. The paper is a brief of the contributions of the team re-search at the project type A applied to CNCSIS ”Research on the Role of Xml in Building Extensible and Homogeneous ERP Systems“.

Advanced eGovernment Information Service Bus (eGov-Bus)
Abstract: The eGov-Bus project provides citizens and businesses with improved access to virtual public services, which are based on existing national eGovernment Web services and which support cross-border life events. Requirements and specific rules of these life events are considered, and personalization of user preferences is supported. eGov-Bus is based on adaptable proc-ess management technologies, allowing for virtual services which are dynamically combined from existing national eGovernment services. In this way, a comprehensive workflow process is set up, allowing for service-level agreements, an audit trail and explanation of the process to the end user. The eGov-Bus process engine operates on top of a virtual repository, provid-ing a high-level semantic view of information retrieved from heterogeneous information sources, such as eGovernment Web services. Further, eGov-Bus relies on a security frame-work to ensure all high-level security requirements are met. The eGov-Bus architecture is business oriented, it focuses on Service Oriented Architecture (SOA) concepts, asynchro-nously combining Web services and providing a Service Bus.
The Use of Features Extracted from Noisy Samples for Image Restoration Purposes
Abstract: An important feature of neural networks is the ability they have to learn from their environ-ment, and, through learning to improve performance in some sense. In the following we re-strict the development to the problem of feature extracting unsupervised neural networks de-rived on the base of the biologically motivated Hebbian self-organizing principle which is conjectured to govern the natural neural assemblies and the classical principal component analysis (PCA) method used by statisticians for almost a century for multivariate data analy-sis and feature extraction. The research work reported in the paper aims to propose a new image reconstruction method based on the features extracted from the noise given by the principal components of the noise covariance matrix.
Information Security Audit in e-business applications
Abstract: Electronic business (e-business) are different than other business because it involves any commercial or business activity that takes place by means of electronic facilities (buy and selling online), including on the Internet, proprietary networks and home banking, instead of through direct physical exchange or contact. This system creates an environment that operates
at a much greater speed than traditional methods and involves much less
paper–based evidence of activities. These e-business related risks
should not be considered in isolation but rather as part of the overall
internal control framework of an entity. It is essential to identify and
assess the risks associated with an e-business environment and
management should develop an e-business strategy that identifies and addresses risks. The e-business Information Systems (IS) audit is a critical component of the e-business plan. This paper tries to present a risk analysis for e-business applications in order to establish the IS audit particularities in this field.
Abstract: E-learning standards refer to a system of common rules for content, authoring software and Learning Management Systems (LMSs) - rules that specify how courses can be created and delivered over multiple platforms so that they all operate seamlessly together. Accredited standards ensure that the investment in time and intellectual capital could move from one sys-tem to the next. Currently, e-learning standards are being developed by four main organiza-tions: AICC, IEEE, IMS, and ADL. The article presents some aspects of theese standards.
The Dynamic Modelling as a Financial Audit Procedure
Abstract: This new procedure of financial audit is based on the requirement that the model should be conceived in such a way that it can reflect in a simplified and accurate manner the ap-proached economic reality.
Unified Approach in the DSS Development Process
Abstract: The structure of today’s decision support environment become very complex due to new gen-eration of Business Intelligence applications and technologies like Data Warehouse, OLAP (On Line Analytical Processing) and Data Mining. In this respect DSS development process are not simple and needs an adequate methodology or framework able to manage different tools and platforms to achieve manager’s requirements. The DSS development process must be view like a unified and iterative set of activities and operations. The new techniques based on Unified Process (UP) methodology and UML (Unified Modeling Language) it seems to be appropriate for DSS development using prototyping and RAD (Rapid Application Develop-ment) techniques. In this paper we present a conceptual framework for development and inte-grate Decision Support Systems using Unified Process Methodology and UML.
The Modeling of the Decisional Process A Case of Study for the Portfolio Management
In the architecture of the management functionality and performance, its decisional compo-nent
has a privileged position. No other element has a more stressed
managerial specificity and a greater impact in all the plans of its
activities and results. There are the main reasons which determined the
authors to do a detailed analyze of the elements which intervene in decisional process. To have as a result a well founded and opportune decision any decisional model had to acquire, process, interpret a larger volume of information, in a shorter period. This demands have directed the whole structure of this paper.
Why should SME adopt IT enabled CRM strategy?
Abstract: Recent trends of fast adoption of CRM, whether as a philosophy, a strategy, an aid to the gen-eral marketing effort and mix, or merely as a fashion; as every body else is doing it; is driven by a clear acknowledgement and recognition that long-term relationships with customers are one of the most important assets of an organisation and that information-enabled systems must be developed that will give the organisation some form of ownership, that is: 'customer ownership'.
The communication process in virtual teams
Abstract: The purpose of this paper is to present the paradigms of virtual teams in the communication process in the context of the existing literature in this field. We argue the above issues and we explore the communication process within virtual teams like an interactive, complex and lim-iting process in connexion with the advantages and disadvantages offered by information technology.

The ProCard mobile banking system
Abstract: The mobile banking involves the use of some mobile telecommunication devices (such phones or PDAs – Personal Digital Assistants) in order to complete, in a secure manner, banking transac-tions (like payments, transfers, account information and so on). It doesn’t matter where the user is physically located. Also, the hour when the services are requested is not important anymore, because, thanks to the internet banking, the offices are virtually opened 24 hours per day.
