Adaptive learning in agents behaviour: A framework for electricity markets simulation

Electricity markets are complex environments, involving a large number of different entities, playing in a dynamic scene to obtain the best advantages and profits. MASCEM (Multi-Agent System for Competitive Electricity Markets) is a multi-agent electricity market simulator that models market players and simulates their operation in the market. Market players are entities with specific characteristics and objectives, making their decisions and interacting with other players. This paper presents a methodology to provide decision support to electricity market negotiating players. This model allows integrating different strategic approaches for electricity market negotiations, and choosing the most appropriate one at each time, for each different negotiation context. This methodology is integrated in ALBidS (Adaptive Learning strategic Bidding System) – a multiagent system that provides decision support to MASCEM's negotiating agents so that they can properly achieve their goals. ALBidS uses artificial intelligence methodologies and data analysis algorithms to provide effective adaptive learning capabilities to such negotiating entities. The main contribution is provided by a methodology that combines several distinct strategies to build actions proposals, so that the best can be chosen at each time, depending on the context and simulation circumstances. The choosing process includes reinforcement learning algorithms, a mechanism for negotiating contexts analysis, a mechanism for the management of the efficiency/effectiveness balance of the system, and a mechanism for competitor players' profiles definition.

Multilayer Perceptron Neural Networks Training Through Charged System Search and its Application for Non-Technical Losses Detection

The non-technical loss is not a problem with trivial solution or regional character and its minimization represents the guarantee of investments in product quality and maintenance of power systems, introduced by a competitive environment after the period of privatization in the national scene. In this paper, we show how to improve the training phase of a neural network-based classifier using a recently proposed meta-heuristic technique called Charged System Search, which is based on the interactions between electrically charged particles. The experiments were carried out in the context of non-technical loss in power distribution systems in a dataset obtained from a Brazilian electrical power company, and have demonstrated the robustness of the proposed technique against with several others natureinspired optimization techniques for training neural networks. Thus, it is possible to improve some applications on Smart Grids.

Strategic Bidding in Electricity Markets: An agent-based simulator with game theory for scenario analysis

Electricity markets are complex environments, involving a large number of different entities, with specific characteristics and objectives, making their decisions and interacting in a dynamic scene. Game-theory has been widely used to support decisions in competitive environments; therefore its application in electricity markets can prove to be a high potential tool. This paper proposes a new scenario analysis algorithm, which includes the application of game-theory, to evaluate and preview different scenarios and provide players with the ability to strategically react in order to exhibit the behavior that better fits their objectives. This model includes forecasts of competitor players’ actions, to build models of their behavior, in order to define the most probable expected scenarios. Once the scenarios are defined, game theory is applied to support the choice of the action to be performed. Our use of game theory is intended for supporting one specific agent and not for achieving the equilibrium in the market. MASCEM (Multi-Agent System for Competitive Electricity Markets) is a multi-agent electricity market simulator that models market players and simulates their operation in the market. The scenario analysis algorithm has been tested within MASCEM and our experimental findings with a case study based on real data from the Iberian Electricity Market are presented and discussed.

Metalearner based on Dynamic Neural Network for Strategic Bidding in electricity Markets

The restructuring of electricity markets, conducted to increase the competition in this sector, and decrease the electricity prices, brought with it an enormous increase in the complexity of the considered mechanisms. The electricity market became a complex and unpredictable environment, involving a large number of different entities, playing in a dynamic scene to obtain the best advantages and profits. Software tools became, therefore, essential to provide simulation and decision support capabilities, in order to potentiate the involved players’ actions. This paper presents the development of a metalearner, applied to the decision support of electricity markets’ negotiation entities. The proposed metalearner executes a dynamic artificial neural network to create its own output, taking advantage on several learning algorithms implemented in ALBidS, an adaptive learning system that provides decision support to electricity markets’ players. The proposed metalearner considers different weights for each strategy, depending on its individual quality of performance. The results of the proposed method are studied and analyzed in scenarios based on real electricity markets’ data, using MASCEM - a multi-agent electricity market simulator that simulates market players’ operation in the market.

A "Portrait" of Book XII of the Æneid: the Mosaic of the «House of the Medusa» (Alter do Chão, Portugal)

This paper addresses the study of a mosaic discovered in 2007 at the archaeological site of Alter do Chão, Portugal, whose central panel represents the penultimate scene narrated in the last Book of the Æneid – a Roman epic composed by the poet Publius Vergilius Maro (70 BC – AD 19), at the request of Gaius Julius Cæsar Octavianus Augustus (63 BC – AD 14): it shows the very moment when Turnus, the Latin king of the Rutuli, kneels before Æneas, considered the precursor to the foundation of Rome (Virgil, Æneid, XII, 926-950).

Podem as nossas leis tornar-nos mais atrativos?

The concept of soft power offers the opportunity for the States, under the current power shifts, to thrive, in a competitive and globalised scene, shaping o t hers' preference in accordance with their goals. Portugal, though it i s a small country, has soft power skills, according with specialized rankings, due to i t s geography and climate, main economic activities, historical role, legal framework, culture and language. Therefore, we can and we should develop public policies to optimize our resources, converting them in planned outcomes. On the other hand, public entities engaged with foreign trade, investment and tour ism, aid f or development, promotion of culture and language should be structured in or-der to strengthen the performance of Portugal in this area. Being a member of the European Union or of the Community of Portuguese Speaking Countries is, at last, essential to expand our global presence. In this Master's work project, I decided to make a critical analysis of legislation related with public diplomacy i n Portugal, together wi th research about the approach of two other countries (United Kingdom and Finland) to the same topic, for the sake of improvement.

Breaking the Pattern and Creating New Paths – Feminist Mizrahi Women Artists in Israel

This article addresses the work of Mizrahi women artists, i.e., Israeli-Jewish women of Asian or African ethnic origin, using the artist Vered Nissim as a case study. Nissim seeks to affirm the politics of identity and recognition, as well as feminism in order to create a paradigm shift with regards to the local regime of cultural representations in the Israeli art scene. Endeavouring to find ways of undermining the rigid imbalances between different social groups, she calls for a comprehensive reform of the status quo through artistic activism. Nissim employs a style, content, and medium that disrupts the accepted social order, using humour and irony as unique weapons with which she takes liberties with conventional moral, social, and economic values. Placing issues of race, class and gender at the centre of her work, she seeks to undermine and problematize essentialist attitudes, highlighting the political intersections of different identity categories as the critical analysis of intersectionality unfolds.

Sentido evolutivo do controle de constitucionalidade no Brasil

Consabido que para uma sociedade organizada se desenvolver política e juridicamente, indispensável se faz a existência de um documento formal, dotado de observância obrigatória, capaz de definir as competências públicas e delimitar os poderes do Estado, resguardando os direitos fundamentais de eventuais abusos dos entes políticos. Este documento é a Constituição, que, em todos os momentos da história, sempre se fez presente nos Estados, mas, inicialmente, não de forma escrita, o que fez com que surgisse, então, o constitucionalismo, movimento que defendia a necessidade de elaboração de constituições escritas, munidas de normatividade e supremacia em relação às demais espécies normativas, que visassem organizar a separação dos poderes estatais e declarar os direitos e as liberdades individuais. Porém, de nada adiantaria a edição de uma Lei Maior sem que houvesse mecanismos de defesa, no intuito de afastar qualquer ameaça à segurança jurídica e à estabilidade social, por conta de alguma lei ou ato normativo contrário aos preceitos estabelecidos na Constituição. O controle de constitucionalidade, pilar do Estado de Direito, consiste em verificar a compatibilidade entre uma lei ou qualquer ato normativo infraconstitucional e a Lei Excelsa e, em havendo contraste, a lei ou o ato viciado deverá ser expurgado do ordenamento jurídico, para que a unidade constitucional seja restabelecida. No Brasil, o controle de constitucionalidade foi instituído sob forte influência do modelo norte-americano e obteve diversos tratamentos ao longo das constituições brasileiras, porém, o sistema de fiscalização de constitucionalidade teve seu ápice com o advento da atual Constituição Federal, promulgada em 05.10.88, com a criação de instrumentos processuais inovadores destinados à verificação da constitucionalidade das leis e atos normativos. Além disso, a Carta da República de 1988, ao contrário das anteriores, fortaleceu a figura do Poder Judiciário no contexto político, conferindo, assim, maior autonomia aos magistrados na solução de casos de grande repercussão nacional, redundando em um protagonismo judicial atual. Nesse contexto, o Supremo Tribunal Federal, órgão de cúpula do Judiciário nacional e guardião da Constituição, tem se destacado no cenário nacional, em especial na defesa dos direitos e garantias fundamentais insculpidos na Lei Fundamental, fazendo-se necessária, desta forma, uma análise na jurisprudência da Corte, no sentido de verificar se, de fato, tem havido evolução no controle de constitucionalidade no Brasil ao longo dos últimos anos e, em caso afirmativo, em que circunstâncias isso tem se dado.

Early processing in the human lateral occipital complex is highly responsive to illusory contours but not to salient regions.

Human electrophysiological studies support a model whereby sensitivity to so-called illusory contour stimuli is first seen within the lateral occipital complex. A challenge to this model posits that the lateral occipital complex is a general site for crude region-based segmentation, based on findings of equivalent hemodynamic activations in the lateral occipital complex to illusory contour and so-called salient region stimuli, a stimulus class that lacks the classic bounding contours of illusory contours. Using high-density electrical mapping of visual evoked potentials, we show that early lateral occipital cortex activity is substantially stronger to illusory contour than to salient region stimuli, whereas later lateral occipital complex activity is stronger to salient region than to illusory contour stimuli. Our results suggest that equivalent hemodynamic activity to illusory contour and salient region stimuli probably reflects temporally integrated responses, a result of the poor temporal resolution of hemodynamic imaging. The temporal precision of visual evoked potentials is critical for establishing viable models of completion processes and visual scene analysis. We propose that crude spatial segmentation analyses, which are insensitive to illusory contours, occur first within dorsal visual regions, not the lateral occipital complex, and that initial illusory contour sensitivity is a function of the lateral occipital complex.

In Search of Corporate Renewal: How to Benefit from Corporate Venturing?

Despite the rapid change in today's business environment there are relatively few studies about corporate renewal. This study aims for its part at filling that research gap by studying the concepts of strategy, corporate renewal, innovation and corporate venturing. Its purpose is to enhance our understanding of how established companies operating in dynamic and global environment can benefit from their corporate venturing activities. The theoretical part approaches the research problem in corporate and venture levels. Firstly, it focuses on mapping the determinants of strategy and suggests using industry, location, resources, knowledge, structure and culture, market, technology and business model to assess the environment and using these determinants to optimize speed and magnitude of change.Secondly, it concludes that the choice of innovation strategy is dependent on the type and dimensions of innovation and suggests assessing market, technology, business model as well as novelty and complexity related to each of them for choosing an optimal context for developing innovations further. Thirdly, it directsattention on processes through which corporate renewal takes place. On corporate level these processes are identified as strategy formulation, strategy formation and strategy implementation. On the venture level the renewal processes are identified as learning, leveraging and nesting. The theoretical contribution of this study, the framework of strategic corporate venturing, joins corporate and venture level management issues together and concludes that strategy processes and linking processes are the mechanism through which continuous corporate renewaltakes place. The framework of strategic corporate venturing proposed by this study is a new way to illustrate the role of corporate venturing as a purposefullybuilt, different view of a company's business environment. The empirical part extended the framework by enhancing our understanding of the link between corporate renewal and corporate venturing in its real life environment in three Finnish companies: Metso, Nokia and TeliaSonera. Characterizing companies' environmentwith the determinants of strategy identified in this study provided a structured way to analyze their competitive position and renewal challenges that they arefacing. More importantly the case studies confirmed that a link between corporate renewal and corporate venturing exists and found out that the link is not as straight forward as indicated by the theory. Furthermore, the case studies enhanced the framework by indicating a sequence according to which the processes work. Firstly, the induced strategy processes strategy formulation and strategy implementation set the scene for corporate venturing context and management processes and leave strategy formation for the venture. Only after that can strategies formed by ventures come back to the corporate level - and if found viable in the corporate level be formalized through formulation and implementation. With the help of the framework of strategic corporate venturing the link between corporaterenewal and corporate venturing can be found and managed. The suggested response to the continuous need for change is continuous renewal i.e. institutionalizing corporate renewal in the strategy processes of the company. As far as benefiting from venturing is concerned the answer lies in deliberately managing venturing in a context different to the mainstream businesses and establishing efficientlinking processes to exploit the renewal potential of individual ventures.
