Abstract
This conceptual paper is developed in the realm of strategic change communication. The purpose of this paper is to present our Business Narrative Modelling Language (BNML) (Oliveira and Ferreira, 2010a) as a tool for facilitating change. We illustrate how BNML has been used in real life cases to discuss strategy. Following data collection using a qualitative methodology and an analysis of the "As-Is" situation we proceed to construct a representation of the future desired ("To-Be") situation, in both situations using BNML. We start by defining the organizational actors relevant to value creation, we then map out their interactions in the organizational context, and study how relevant deliverables are exchanged, both tangible and intangible, along various storylines, one per actor. The social interaction leading to value creation happens according to a pattern sequence (using patterns taken from Bjork and Holopainen, 2005, which are intuitively comprehensible) and is instantiated according to an Enterprise Ontology (Uschold et al., 1998) (Oliveira and Ferreira, 2010a, b). By combining various sensemaking strategies such as the narrative, visual mapping and quantification our BNML scores high on accuracy, simplicity and generality (Langley, 1999) thus providing an attractive alternative to other techniques available to researchers and consultants and used to "connect and organize dispersed organizational knowledge" (Huff and Jenkins, 2002, p. 14).

Abstract
In this paper, the development of bidding strategies is investigated for a wind farm owner. The optimization model is characterized by making the analysis of scenarios. The proposed approach allows evaluating alternative production strategies in order to submit bids to the electricity market with the goal of maximizing profits. The problem is formulated as a linear programming problem. An application to a case study is presented Copyright

Abstract
In this paper, a mixed-integer nonlinear approach is proposed to support decision-making for a hydro power producer, considering a head-dependent hydro chain. The aim is to maximize the profit of the hydro power producer from selling energy into the electric market. As a new contribution to earlier studies, a risk aversion criterion is taken into account, as well as head-dependency. The volatility of the expected profit is limited through the conditional value-at-risk (CVaR). The proposed approach has been applied successfully to solve a case study based on one of the main Portuguese cascaded hydro systems. Copyright

Abstract
In the context of telecommunications networks, the concept of self-organisation implies the introduction of functionalities that lead to the automation of network operational tasks and reduce the need for manual intervention. By introducing Self-Organising Networks (SON) and their self-x functionalities several technical and business gains are expected: increase of spectral efficiency, provision of DSA mechanisms and enhancement of radio resource management, improvement of QoS and QoE, lower cost of ownership, reduction of OPEX and increase of service value. In order to assess the trade-off between costs and benefits of future investments in SON, this paper intends to qualify the impact of each self-x functionality in the business of operators, as well as identify the requirements and the value delivered to the various actors of the value network.

Abstract
Many musical works produced in the past are still currently available only as original manuscripts or as photocopies. The preservation of these works requires their digitalization and transformation into a machine-readable format. However, and despite the many research activities on optical music recognition (OMR), the results for handwritten musical scores are far from ideal. Each of the proposed methods lays the emphasis on different properties and therefore makes it difficult to evaluate the efficiency of a proposed method. We present in this article a comparative study of several recognition algorithms of music symbols. After a review of the most common procedures used in this context, their respective performances are compared using both real and synthetic scores. The database of scores was augmented with replicas of the existing patterns, transformed according to an elastic deformation technique. Such transformations aim to introduce invariances in the prediction with respect to the known variability in the symbols, particularly relevant on handwritten works. The following study and the adopted databases can constitute a reference scheme for any researcher who wants to confront a new OMR algorithm face to well-known ones.

Abstract
In this work, two all-fibre interferometric configurations based on suspended core fibres (SCF) are investigated. A Fabry-Perot cavity made of SCF spliced in-between segments of single-mode and hollow-core fiber is proposed. An alternative sensing head configuration formed by the insertion of a length of SCF as a birefringence element in a Sagnac interferometer is also demonstrated. The sensitivity to pressure and temperature was determined for both configurations.
