Shared visiting in Equator city

In this paper we describe an infrastructure and prototype system for sharing of visiting experiences across multiple media. The prototype supports synchronous co-visiting by physical and digital visitors, with digital access via either the World Wide Web or 3-dimensional graphics

COMPANIES ECONOMY IN CONTEXT OF THE ECONOMIC CRISIS

In this article I try to express components of the market economy which may affect an organization of the companies into a period whith decline and resignation reign in human activities. The economic crisis that is the a current world is the climax of financial turmoil which make integral part a normal legislative and the economic calculation which configures a demand and supply of goods.organizational arrangements; company; contracts; legislation; demand; supply; Microeconomics; economic calculation

Comparative Study on Agile software development methodologies

Today-s business environment is very much dynamic, and organisations are constantly changing their software requirements to adjust with new environment. They also demand for fast delivery of software products as well as for accepting changing requirements. In this aspect, traditional plan-driven developments fail to meet up these requirements. Though traditional software development methodologies, such as life cycle-based structured and object oriented approaches, continue to dominate the systems development few decades and much research has done in traditional methodologies, Agile software development brings its own set of novel challenges that must be addressed to satisfy the customer through early and continuous delivery of the valuable software. It is a set of software development methods based on iterative and incremental development process, where requirements and development evolve through collaboration between self-organizing, cross-functional teams that allows rapid delivery of high quality software to meet customer needs and also accommodate changes in the requirements. In this paper, we significantly identify and describe the major factors, that Agile development approach improves software development process to meet the rapid changing business environments. We also provide a brief comparison of agile development methodologies with traditional systems development methodologies, and discuss current state of adopting agile methodologies. We speculate that from the need to satisfy the customer through early and continuous delivery of the valuable software, Agile software development is emerged as an alternative to traditional plan-based software development methods. The purpose of this paper, is to provide an in-depth understanding, the major benefits of agile development approach to software development industry, as well as provide a comparison study report of ASDM over TSDM.Comment: 25 pages, 25 images, 86 references used, with authors biographie

Using mobile RE tools to give end-users their own voice

Researchers highlight end-user involvement in system design as an important concept for developing useful and usable solutions. However, end-user involvement in software engineering is still an open-ended topic. Novel paradigms such as service-oriented computing strengthen the need for more active end-user involvement in order to provide systems that are tailored to individual end-user needs. Our work is based on the fact that the majority of end-users are familiar with mobile devices and use an increasing number of mobile applications. A mobile tool enabling end-user led requirements elicitation could be just one of many applications installed on end-users' mobile devices. In this paper, we present a framework of end-user involvement in requirements elicitation which motivates our research. The main contribution of our research is a tool-supported requirements elicitation approach allowing end-users to document needs in situ. Furthermore, we present first evaluation results to highlight the feasibility of on-site end-user led requirements elicitation

A proposal to delegate GUI implementation using a source code based model

In this paper we propose an architecture whose main goal is to improve productivity in user interface development for data-intensive applications. This objective is to be achieved by defining a high level model that describes the user interface structure. That model will be integrated in the source code through non-functional language extensions. Our final goal is allowing developers to define user interface model by adding language extensions to the source code and then acquiring an external software package to which they delegate the implementation of the concrete user interface

Identification of suitable web application development methods for small software firms

Many development methods have been proposed for developing web application in small software firms.However, these methods have some limitations.This paper aims to identify the suitable development methods for building high quality web application.In order to achieve this objective, a comparative study was conducted on several current development methods.Comparisons were made according to five criteria that include fitted to 10-50 size, simplicity, flexible to change, customer collaboration and quality assurance used measurement program(QAMP).The findings of this paper will be used as a baseline for building a new development methodology for small software firms that emphasize on monitoring
