Abstract
This paper seeks to give a general idea of the universe of project portfolio management, from its multidisciplinary nature, to the many challenges it raises, passing through the different techniques, models and tools used to solve the multiple problems known. It is intended to contribute to the clarification, with great depth, of the impacts and relationships involved in managing the projects' portfolio. It aims at proposing a technique for the project alignment with the organisational strategy, in order to select projects that later on will be considered in the analysis and selection of the portfolio. We consider the development of a methodology for assessing the project alignment index very relevant in the global market scenario. It can help organisations to gain a greater awareness of market dynamics, speed up the decision process and increase its consistency, thus enabling the strategic alignment and the improvement of the organisational performance.

Abstract
This paper presents the participation of distributed generation and interruptible loads for Demand Side Management (DSM) in market environment. This contribution has two aspects, first, the technical requirements that should be implemented on these applications. Then the way DGs and ILs are offered in market and what should be included in their contracts. In this paper the above mentioned issues will be discussed and a database system will be presented by which a Disco can deal with interruptible loads and distributed generations simultaneously in its contracts.

Abstract
Digital medical imaging poses challenging requirements to computer science, calling for methods able to efficiently address large data sets and complex processing. Production Grid infrastructures are available, ready to provide on-demand scalable processing power and robust storage. These infrastructures, however, still expose many technical complexities to end-users and domain application developers. In this context, the ability to access Grid services in a seamless, user-friendly way is paramount to bring the Grid potential to clinical users and biomedical researchers. In this paper, we present a Grid-interfacing portal, aiming at raising the level of usability of the Grid to medical research users. In the MAGI portal, the researcher works with domain semantics, including concepts like subject, study and dataset, while the Grid operations, specially storage, are transparently supported by a services framework we have developed. The framework provides high-level, application-developer friendly services to interface the gLite middleware. The portal was also designed to support intuitive, visual interactions, like drag-and-drop, to execute the main use cases.

Abstract
In this paper, we report the impact of the parasitic capacitances in the modeling and analysis of advanced floating gate (FG) non-volatile memory (NVM) devices, especially on the coupling ratio. Due to the poor accuracy of the existing capacitance model when compared to practice, an approach to include the parasitic capacitances has been established. Measurement results from two transistor (2T) Fowler-Nordheim (FN) tunneling operated flash memory show a good improvement in the model accuracy. The parasitic capacitances depend very much on the floating gate dimension, and the spacing to the neighboring elements in the flash cell array. The growing influence of the parasitic capacitances and the subsequent degradation of the existing model accuracy can be expected for the cells dimensions in future process technologies. With the accurate calculation method for the parasitic capacitances proposed in this paper, the cell characteristics can be more accurately modeled, andthe degradation of the cell can be accurately studied. ©2009 IEEE.

Abstract
Necessary Conditions of Optimality (NCO) play an important role in the characterization of and search for solutions of Optimization Problems. They enable us to identify a small set of candidates to local minimizers among the overall set of admissible solutions. However, in constrained optimization problems it may happen that necessary conditions of optimality are merely state a relation between the constraints and do not use the objective function to select candidates to minimizers. To avoid this phenomenon, it is necessary to strengthened the NCO. Here, we overview and describe strengthened forms NCO for calculus of variations with inequality constraints.
