Web Systems

The great advance of the communications and the importance gained by the mobile systems have increased the development of WAP (Wireless Application Protocol) applications, nevertheless at the present time do not exist methodologies specifically designed for the WAP applications development process. However, in the last years, several methodologies for the web applications development process have been proposed. One of them is UWE (UML-based Web Engineering) [1]. Although this methodology has specifically been developed for web applications, the similarity between web and WAP systems allows us to propose the use of it, to generate a design stage approach for WAP applications and then to create a specific extension of UWE to build WAP applications. In order to obtain this, we present a new UWE based model called WAP navigational model for the navigational design and presentational design steps, which we can use to design WAP systems improving the WAP applications development process.

Agile methodologies are being touted as the next major paradigm shift in development of information systems. However, there is little empirical evidence to determine how well suited agile methodologies such as Extreme Programming (XP) are for fast paced web development. This paper presents the findings of an empirical study that investigates the suitability of XP for web development. Evidence from the findings would suggest that there are many benefits to be gained from using XP. However, there are also many problems in using such an approach because web development is embedded in HTML. However, as the Web becomes more object-oriented with emergence of Web services, agile methodologies such as XP will become increasingly important and more suited to web development.

During 1996 the world's attention was captured by the litigation posed by the United States' government against Microsoft, blaming the latter of abusive use of its monopoly power in order to win what was known as the "browser's war". This paper presents the previous scenario to the web browser's battle carried out by Microsoft and Netscape, analyzing both firm's strategies in a short and also in a long term horizon game. The study provided is based on game theory tools and attempts to give a model that explains the firms' behavior. Although the presented model is quite simple, it accurately explains the strategic interaction between the firms and its predictions fits with the actual results.

The application of multi-tag protocols in fluorescence microscopy allows the visualization of a large number (> 10) of molecules (i. e. proteins) in a sample (like a tissue section). However, the analysis of such high dimensional bioimages is a difficult task for most of the labs, since software solutions for particular data mining steps are difficult to use or just not available. In this paper we present two new free online tools: MICOLT (Multivariate Image COlocation Tool) and MIFIST (Multivariate Image Frequent Item Set Tool). Both tools can be used via our recently proposed online bioimage analysis platform BioIMAX, so users can upload their bioimage data, apply the tools and share the results with other invited users based on BioIMAX' concept of shared virtual projects. Data mining with these tools includes the computation and visualization colocation factors well established in the microscopy community (like Mander's score) and association rule mining following the frequent item set principle, thereby supporting large and small scale analysis.

This paper presents the project iReport SportsInjuries, which is a system with a focus on a Web application directed to sport health professionals, supporting the acquisition, analysis and dissemination of sports injuries information. This software will allow health professionals register and analyze sports injuries among sports populations. The application provides a reporting module that includes tables and charts to individually analyze injuries of a specific sports organization, a specific sport across organizations or a specific athlete, independently of where s/he practices. The system also offers a module for a global analysis, which allows the iReport SportsInjuries to obtain the incidence and prevalence values, besides the socioeconomics costs, regarding sports injuries at a national level. In order to offer these features, it is based on a global sports injuries model with the goal of standardizing data related to the sports injuries subject.

La referencia como tal ha sufrido cambios en los últimos años, en los que ha agregado a sus recursos herramientas tecnológicas que han dinamizado los servicios que la componen. Los autores que han estudiado esta disciplina presentan varias clasificaciones de sus servicios y, en ocasiones, difieren en opinión unos de otros, por lo que resulta difícil obtener una visión clara de la diferencia entre los tipos de referencia que se estudian. Hasta el momento, el estudio de la referencia se limitaba a esta visión basada en clasificaciones; no obstante, tras el análisis del comportamiento evolutivo de los servicios y herramientas que conforman esta disciplina, se propone, a través del siguiente artículo, visualizar la referencia como una única figura que se encuentra en constante evolución.

In the currents processes of manufacture, data proceeding from field equipments needs to be controlled. This data provide information that can help in the business decision of a company. This work focuses the necessity to have an efficient system of capture and data storage, proceeding from production cells of industrial processes.

This paper addresses the modeling and development of a system of data management systems based on PIMS. In this case a software must collect data from sensors, apply a compression algorithm on these data, store this information in a database and display them through a web application. For testing purposes, the system developed is used to automate a station dedicated to the remote monitoring of solarimetric variables. The system goal is to provide high rates of data compression, resulting in a performance gain of the system, maintaining the philosophy of freeware.

Las Unidades de Información han enfrentado cambios con el pasar de los años, lograron adaptarse, crecer y en la mayoría de los casos evolucionar. Algunas mejoran sus servicios, productos y llegan a una mayor cantidad y calidad de usuarios. Sin embargo, esta evolución no ha sido igual para todas, muchas se han quedado en el camino. La evolución ha sido provocada principalmente por los avances en la tecnología; los sistemas rígidos de administración y descripción bibliográfica deberían ser historia. En la actualidad, los sistemas son en ambiente web y permiten utilizar las herramientas, el almacenaje y acceso en la nube. Es necesario que las bibliotecas exploten las oportunidades que las tecnologías, herramientas y plataformas móviles proporcionan; accesos ilimitados, mayor captura de usuarios según sus intereses individuales o grupales. Las aplicaciones móviles son un mercado que las bibliotecas deben aprovechar, su desarrollo debe dejar de ser un obstáculo para los profesionales de la información. En el momento que las unidades de información desarrollen y personalicen sus propias herramientas y aplicaciones web, la brecha informacional de sus usuarios gradualmente desaparecerá, un desafío que vale la pena el esfuerzo.

The Information Units have faced changes along with society; they manage to adapt and in most cases evolve to improve with services and products to reach and satisfy a greater quantity of users.  Nevertheless, this evolution caused mainly by the advances in technology, has not been equal for all and many libraries have remained on the road with dated administration systems and stiff bibliographical description that should be history.  Currently, the system in the web environment provides the tools, the storage and access in the cloud.  Librarians today must take advantage of the opportunities of such technological innovations in order to develop its own tools and customize useful mobile “apps” to deliver unlimited access and attract users according to their individual or group interests so to diminish the user´s information gap, a challenge worthwhile the effort.
