Pruebas de Software. Fundamentos y Técnicas

Este proyecto estudia los fundamentos y las técnicas de las pruebas de software. Veremos lo importante que pueden llegar a ser las pruebas, mostrando diferentes desastres causados por fallos en el software. También estudiaremos las diferentes herramientas que se utilizan para llevar a cabo la gestión, administración y ejecución de estas pruebas. Finalmente aplicaremos los conceptos estudiados mediante un caso práctico. Crearemos los casos de prueba funcionales basándonos en las especificaciones del protocolo MDB/ICP e instalaremos y aprenderemos cómo crear estos casos con una de las herramientas estudiadas en la parte teórica. ABSTRACT: This project studies the fundamentals and techniques of software testing. We will see how important the evidence showing different disasters caused by bugs in the software can become. We will also study the different tools used to carry out the management, administration and execution of these tests. Finally, we apply the concepts studied by a case study. We create test cases based on functional specifications MDB/ICP protocol We will install and learn how to create such cases by one of the tools studied in the theoretical part.

Modelling sediment delivery ratio over the Murray Darling Basin

This paper presents a scientific and technical description of the modelling framework and the main results of modelling the long-term average sediment delivery at hillslope to medium-scale catchments over the entire Murray Darling Basin (MDB). A theoretical development that relates long-term averaged sediment delivery to the statistics of rainfall and catchment parameters is presented. The derived flood frequency approach was adapted to investigate the problem of regionalization of the sediment delivery ratio (SDR) across the Basin. SDR, a measure of catchment response to the upland erosion rate, was modeled by two lumped linear stores arranged in series: hillslope transport to the nearest streams and flow routing in the channel network. The theory shows that the ratio of catchment sediment residence time (SRT) to average effective rainfall duration is the most important control in the sediment delivery processes. In this study, catchment SRTs were estimated using travel time for overland flow multiplied by an enlargement factor which is a function of particle size. Rainfall intensity and effective duration statistics were regionalized by using long-term measurements from 195 pluviograph sites within and around the Basin. Finally, the model was implemented across the MDB by using spatially distributed soil, vegetation, topographical and land use properties under Geographic Information System (GIs) environment. The results predict strong variations in SDR from close to 0 in floodplains to 70% in the eastern uplands of the Basin. (c) 2005 Elsevier Ltd. All rights reserved.

Process orientation and information technology:customer engagement at Xerox (UK) Ltd

Xerox Customer Engagement activity is informed by the "Go To Market" strategy, and "Intelligent Coverage" sales philosophy. The realisation of this philosophy necessitates a sophisticated level of Market Understanding, and the effective integration of the direct channels of Customer Engagement. Sophisticated Market Understanding requires the mapping and coding of the entire UK market at the DMU (Decision Making Unit) level, which in turn enables the creation of tailored coverage prescriptions. Effective Channel Integration is made possible by the organisation of Customer Engagement work according to a single, process defined structure: the Selling Process. Organising by process facilitates the discipline of Task Substitution, which leads logically to creation of Hybrid Selling models. Productive Customer Engagement requires Selling Process specialisation by industry sector, customer segment and product group. The research shows that Xerox's Market Database (MDB) plays a central role in delivering the Go To Market strategic aims. It is a tool for knowledge based selling, enables productive SFA (Sales Force Automation) and, in sum, is critical to the efficient and effective deployment of Customer Engagement resources. Intelligent Coverage is not possible without the MDB. Analysis of the case evidence has resulted in the definition of 60 idiographic statements. These statements are about how Xerox organise and manage three direct channels of Customer Engagement: Face to Face, Telebusiness and Ebusiness. Xerox is shown to employ a process-oriented, IT-enabled, holistic approach to Customer Engagement productivity. The significance of the research is that it represents a detailed (perhaps unequalled) level of rich description of the interplay between IT and a holistic, process-oriented management philosophy.

Evaluación del estado poblaciónal del Cangrejo violáceo Platyxanthus orbignyi (Milne Edwards y Lucas, 1843) del área de Lambayeque por medio de un modelo dinámico de Biomasa

Se hace un análisis del estado poblacional del cangrejo violáceo Platyxanthus orbignyi (Milne Edwards y Lucas, 1843) del litoral de Lambayeque – Perú para el periodo 2001-2010 por medio de: 1) El modelo dinámico de biomasa de Schaefer en su versión de error de observación; a este modelo se le introdujo la variable ambiental anomalía de la temperatura superficial del mar (ATSM) del área de San José (Lambayeque) y se obtuvo 2) el modelo dinámico con variable ambiental, ambos basados en datos de captura, esfuerzo y CPUE. Se utilizó el método de máxima verosimilitud en el proceso de ajuste y el bootstrap para determinar los intervalos de confianza de los parámetros. Los parámetros poblacionales y pesqueros estimados por el modelo dinámico de biomasa de Schaefer (MDB) fueron: K: 750 000 kg, r : 0,21 y q: 8,36 x 10-6 y por el modelo dinámico con variable ambiental (MDVA) los parámetros fueron K: 765 000 kg, r: 0,23 y q: 8,02 x 10-6. Con los valores de los parámetros estimados mediante el MDB y el MDVA se calcularon los principales puntos biológicos de referencia (PBR) los cuales fueron: MRS: 39 822 kg, BMRS: 375 000 kg, fMRS: 12 561 nasas, FMRS: 0,11, F0.1: 0,10 para el MDB; y MRS: 44 069 kg, BMRS: 382 500 kg, fMRS: 13 782 nasas, FMRS: 0,12, F0.1: 0,10 para el MDVA. Los resultados indican que el estado actual de la pesquería del cangrejo violáceo del Litoral de Lambayeque se encuentra muy cerca al nivel óptimo. En vista de que no se dispone de información de evaluaciones directas de este recurso que confirme o no los resultados del MDB y MDVA y en virtud de la calidad de datos, se sugiere que el manejo de la pesquería sea del tipo adaptativo alrededor del punto de referencia F0.1 y teniendo en cuenta las condiciones ambientales.

The evolution and performance of river basin management in the Murray-Darling Basin

We explore bioregional management in the Murray-Darling Basin (MDB) in Australia through the institutional design characteristics of the MDB River Basin Organization (RBO), the actors and organizations who supported and resisted the establishment of the RBO, and the effectiveness of the RBO. During the last 25 years, there has been a major structural reform in the MDB RBO, which has changed from an interstate coordinating body to an Australian government agency. Responsibility for basin management has been centralized under the leadership of the Australian government, and a comprehensive integrated Basin plan has been adopted. The driving forces for this centralization include national policy to restore river basins to sustainable levels of extraction, state government difficulties in reversing overallocation of water entitlements, the millennium drought and its effects, political expediency on the part of the Australian government and state governments, and a major injection of Australian government funding. The increasing hierarchy and centralization of the MDB RBO does not follow a general trend toward multilevel participative governance of RBOs, but decentralization should not be overstated because of the special circumstances at the time of the centralization and the continuing existence of some decentralized elements, such as catchment water plans, land use planning, and water quality. Further swings in the centralization–decentralization pendulum could occur. The MDB reform has succeeded in rebalancing Basin water allocations, including an allocation for the environment and reduced diversion limits. There are some longer term risks to the implementation of reform, including lack of cooperation by state governments, vertical coordination difficulties, and perceived reductions in the accountability and legitimacy of reform at the local level. If implementation of the Basin plan is diverted or delayed, a new institution, the Commonwealth Environmental Water Holder, can play a major role in securing and coordinating environmental water supplies.
