Framework for the semantic alignment of enterprise’s domain knowledge

Nowadays, the consumption of goods and services on the Internet are increasing in a constant motion. Small and Medium Enterprises (SMEs) mostly from the traditional industry sectors are usually make business in weak and fragile market sectors, where customized products and services prevail. To survive and compete in the actual markets they have to readjust their business strategies by creating new manufacturing processes and establishing new business networks through new technological approaches. In order to compete with big enterprises, these partnerships aim the sharing of resources, knowledge and strategies to boost the sector’s business consolidation through the creation of dynamic manufacturing networks. To facilitate such demand, it is proposed the development of a centralized information system, which allows enterprises to select and create dynamic manufacturing networks that would have the capability to monitor all the manufacturing process, including the assembly, packaging and distribution phases. Even the networking partners that come from the same area have multi and heterogeneous representations of the same knowledge, denoting their own view of the domain. Thus, different conceptual, semantic, and consequently, diverse lexically knowledge representations may occur in the network, causing non-transparent sharing of information and interoperability inconsistencies. The creation of a framework supported by a tool that in a flexible way would enable the identification, classification and resolution of such semantic heterogeneities is required. This tool will support the network in the semantic mapping establishments, to facilitate the various enterprises information systems integration.

Methodological framework for detection of harmonisation breaking in service environments

As the complexity of markets and the dynamicity of systems evolve, the need for interoperable systems capable of strengthening enterprise communication effectiveness increases. This is particularly significant when it comes to collaborative enterprise networks, like manufacturing supply chains, where several companies work, communicate, and depend on each other, in order to achieve a specific goal. Once interoperability is achieved, that is once all network parties are able to communicate with and understand each other, organisations are able to exchange information along a stable environment that follows agreed laws. However, as markets adapt to new requirements and demands, an evolutionary behaviour is triggered giving space to interoperability problems, thus disrupting the sustainability of interoperability and raising the need to develop monitoring activities capable of detecting and preventing unexpected behaviour. This work seeks to contribute to the development of monitoring techniques for interoperable SOA-based enterprise networks. It focuses on the automatic detection of harmonisation breaking events during real-time communications, and strives to develop and propose a methodological approach to handle these disruptions with minimal or no human intervention, hence providing existing service-based networks with the ability to detect and promptly react to interoperability issues.

A model to screen and improve business potential of micro and small enterprises in developing countries: Evidence from the Island of Mozambique

Programmes supporting micro and small enterprises in developing countries have been showing that capital is not enough to allow business success: survival and growth. Literature does not provide comprehensive and practical tool to support business development in this context, but allowed the collection of forty-nine success variables that were studied in a sample of successful and unsuccessful businesses in the Island of Mozambique to discover what were the key factors affecting those businesses’ performance. Empirical data gave the insights for the development of a model to screen and improve business potential of micro and small enterprises in this context.

DYNAMOD – A dynamic agent based modelling framework for digital businesses

Digital Businesses have become a major driver for economic growth and have seen an explosion of new startups. At the same time, it also includes mature enterprises that have become global giants in a relatively short period of time. Digital Businesses have unique characteristics that make the running and management of a Digital Business much different from traditional offline businesses. Digital businesses respond to online users who are highly interconnected and networked. This enables a rapid flow of word of mouth, at a pace far greater than ever envisioned when dealing with traditional products and services. The relatively low cost of incremental user addition has led to a variety of innovation in pricing of digital products, including various forms of free and freemium pricing models. This thesis explores the unique characteristics and complexities of Digital Businesses and its implications on the design of Digital Business Models and Revenue Models. The thesis proposes an Agent Based Modeling Framework that can be used to develop Simulation Models that simulate the complex dynamics of Digital Businesses and the user interactions between users of a digital product. Such Simulation models can be used for a variety of purposes such as simple forecasting, analysing the impact of market disturbances, analysing the impact of changes in pricing models and optimising the pricing for maximum revenue generation or a balance between growth in usage and revenue generation. These models can be developed for a mature enterprise with a large historical record of user growth rate as well as for early stage enterprises without much historical data. Through three case studies, the thesis demonstrates the applicability of the Framework and its potential applications.

Cumprimento de ordens, obediência hierárquica e disciplina militar versus perpetração (in)voluntária de crimes

Following orders, hierarchical obedience and military discipline are essential values for the survival of the armed forces. Without them, it is not possible to conceive the armed forces as an essential pillar of a democratic state of law and a guarantor of national independence. As issuing orders as well as receiving and following them are inextricably linked to military discipline, and as such injunctions entail the workings of a particular obedience regime within the specific kind of organized power framework which is the Armed Forces, only by analysing the importance of such orders within this microcosm – with its strict hierarchical structure – will it be possible to understand which criminal judicial qualification to ascribe to the individual at the rear by reference to the role of the front line individual (i.e. the one who issues an order vs the one who executes it). That is, of course, when we are faced with the practice of unlawful acts, keeping in mind the organizational framework and its influence over the will of the executor. One thing we take as read, if the orders can be described as unlawful, the boundary line of the duty of obedience, which cannot be overstepped, both because of a legal as well as a constitutional imperative, will have been crossed. And the military have sworn an oath of obedience to the fundamental law. The topic of hierarchical obedience cannot be separated from the analysis of current legislation which pertains to the topic within military institutions. With that in mind, it appeared relevant to address the major norms which regulate the matter within the Portuguese military legal system, and, whenever necessary and required by the reality under analysis, to relate that to civilian law or legal doctrine.

Knowledge management framework based on brain models and human physiology

The life of humans and most living beings depend on sensation and perception for the best assessment of the surrounding world. Sensorial organs acquire a variety of stimuli that are interpreted and integrated in our brain for immediate use or stored in memory for later recall. Among the reasoning aspects, a person has to decide what to do with available information. Emotions are classifiers of collected information, assigning a personal meaning to objects, events and individuals, making part of our own identity. Emotions play a decisive role in cognitive processes as reasoning, decision and memory by assigning relevance to collected information. The access to pervasive computing devices, empowered by the ability to sense and perceive the world, provides new forms of acquiring and integrating information. But prior to data assessment on its usefulness, systems must capture and ensure that data is properly managed for diverse possible goals. Portable and wearable devices are now able to gather and store information, from the environment and from our body, using cloud based services and Internet connections. Systems limitations in handling sensorial data, compared with our sensorial capabilities constitute an identified problem. Another problem is the lack of interoperability between humans and devices, as they do not properly understand human’s emotional states and human needs. Addressing those problems is a motivation for the present research work. The mission hereby assumed is to include sensorial and physiological data into a Framework that will be able to manage collected data towards human cognitive functions, supported by a new data model. By learning from selected human functional and behavioural models and reasoning over collected data, the Framework aims at providing evaluation on a person’s emotional state, for empowering human centric applications, along with the capability of storing episodic information on a person’s life with physiologic indicators on emotional states to be used by new generation applications.

Otimização da técnica de micro Fluorescência de Raios- X para o estudo de ossos

Nos países desenvolvidos, as doenças reumáticas são o grupo de doenças mais fre-quentes da espécie humana, sendo por isso o primeiro motivo de consulta nos cuidados de saúde primários e a principal causa de incapacidade temporária para o trabalho e de reformas antecipadas por doença/invalidez (Canhão & Branco, 2013). O estudo destas doenças torna-se cada vez mais urgente visto que estas têm tendência crescente, tendo em conta os atuais esti-los de vida e o aumento da longevidade da população. Nesta dissertação foi estudada e otimi-zada a técnica de Micro Fluorescência de Raios-X (μ-XRF) de forma a permitir um estudo de elementos maioritários e elementos traço em ossos com doenças reumáticas, tendo em espe-cial atenção a razão Ca/P, já que, por estudos até agora efetuados, esta razão é considerada um biomarcador adequado para a avaliação da saúde dos ossos. Foram então verificados os erros aleatórios e sistemáticos existentes nesta técnica e concluiu-se quais os tipos de parâme-tros que devem ser tidos em conta para este estudo, tais como corrente, tensão do tubo, filtros, entre outros. As amostras foram ainda analisadas com a técnica de PIGE (Particle Induced Gamma-ray Emission) e comparados os resultados com os de μ-XRF de forma a avaliar a in-fluência da topologia da amostra. Pretende-se que este estudo seja o início do desenvolvimen-to de um método alternativo de diagnóstico precoce de doenças reumáticas, conduzindo a um tratamento mais eficaz e melhorando assim a qualidade de vida da população.

Caraterização metrológica de contadores de micro caudal

Nas últimas décadas, as empresas têm sido sujeitas a uma maior concorrência, ao desenvolvimento tecnológico mais acelerado e a novos desafios no que respeita à qualidade. A Metrologia deverá assim acompanhar estas tendências do mercado. O Departamento de Metrologia (DMET) do Instituto Português da Qualidade, I.P. (IPQ) tem vindo a desenvolver esforços significativos que visam a melhoria contínua das técnicas e dos processos de medição e de calibração realizados nos laboratórios. A presente dissertação de mestrado foi realizada no Laboratório de Volume e Caudal (LVC) do DMET. Os objetivos iniciais do trabalho centraram-se na caraterização metrológica de contadores de fluidos, tendo como base a medição do caudal, utilizando como método de referência o método gravimétrico. De forma a validar o sistema de medição foram realizados ensaios entre 1 mL/h a 100 mL/h, em condições de reprodutibilidade, com dois sistemas padrão distintos de acordo com o caudal a ensaiar. Em todos os ensaios efetuados foi necessário monitorizar as condições ambientais, i.e. temperatura, pressão atmosférica, humidade relativa e a temperatura do líquido padrão, para a aplicação das correções necessárias. Outro feito importante foi a caraterização das fontes de incerteza, que permitiram caraterizar o resultado das medições. A metodologia utilizada para a avaliação e para a estimativa da incerteza de medição encontra-se descrita no Guide to the Expression of Uncertainty in Measurement (GUM). Neste projeto foram contempladas fontes de incerteza como as associadas à evaporação, à impulsão do tubo, à resolução da balança, entre outras. Com os resultados obtidos foi possível elaborar um procedimento técnico para a Calibração de Caudalímetros de Líquidos. Os resultados obtidos permitiram garantir a rastreabilidade das medições de caudal de líquidos ao SI, essencial para a calibração de equipamentos no Laboratório Nacional de Metrologia (LNM) do IPQ, nomeadamente para micro caudalímetros no intervalo de medição entre 0,12 mL/h e 600 mL/h.

Análise comparativa da designação, definição e classificação de resíduos hospitalares em legislações da União Europeia

RESUMO - O quadro legislativo de um país, no que concerne aos resíduos hospitalares (RH), contém a sua designação, definição e classificação. É essa a matriz de referência para a separação efectuada na origem e todo o circuito que, a partir desse momento, um determinado resíduo toma até ao seu tratamento. Assim, faz-se o estudo comparativo das definições e tipos de classificação de RH em quatro países da União Europeia: Alemanha, Reino Unido, Espanha (Região Autónoma da Catalunha) e Portugal. Reconhecem-se as diferentes designações deste tipo de resíduos e discute-se o seu significado e as suas implicações na percepção de risco por parte dos profissionais e do público. Identificam-se duas estratégias subjacentes à elaboração das definições: a contaminação de materiais com microrganismos patogénicos bem definidos, as suas fontes e as actividades que os produzem. Apresentam-se as classificações de RH propostas pelos organismos internacionais de referência e analisa-se comparativamente a evolução do enquadramento legal português e da Região Autónoma da Catalunha, evidenciando-se a variabilidade temporal e justificando-se a necessidade de se efectuar o estudo da variabilidade geográfica. Utilizam-se três critérios para a análise das classificações consideradas: a concordância definição-classificação, o número e tipo de grupos das classificações e os tipos de resíduos por grupos. Identificam-se os denominadores comuns às classificações analisadas, assim como as suas principais diferenças. Conclui-se que a definição de RH adoptada por cada país condiciona o tipo de classificação de RH nesse mesmo país. Verifica-se ainda que a inexistência de critérios claros de avaliação da contaminação pode dificultar a tarefa da triagem dos RH por parte dos profissionais de saúde.

The Beglocal framework applied to B2C E-commerce

This case-study examined the use of the BeGloCal Framework applied to B2C E-commerce, for a fast moving consumer goods European manufacturing firm. It explains how the framework supported the team within the company to identify the right local market as to where to start the project, the problem for the company was to find the most appealing area to invest resources. By going through all the steps of the framework the findings led the company to London (Kensington and Chelsea). It shows how managers should act when they have to find a trade-off between standardization and adaptation.

A new credit monitoring framework for agents' networks

The purpose of this work is to develop a practicable approach for Telecom firms to manage the credit risk exposition to their commercial agents’ network. Particularly it will try to approach the problem of credit concession to clients’ from a corporation perspective and explore the particular scenario of agents that are part of the commercial chain of the corporation and therefore are not end-users. The agents’ network that served as a model for the presented study is composed by companies that, at the same time, are both clients and suppliers of the Telecommunication Company. In that sense the credit exposition analysis must took into consideration all financial fluxes, both inbound and outbound. The current strain on the Financial Sector in Portugal, and other peripheral European economies, combined with the high leverage situation of most companies, generates an environment prone to credit default risk. Due to these circumstances managing credit risk exposure is becoming increasingly a critical function for every company Financial Department. The approach designed in the current study combined two traditional risk monitoring tools: credit risk scoring and credit limitation policies. The objective was to design a new credit monitoring framework that is more flexible, uses both external and internal relationship history to assess risk and takes into consideration commercial objectives inside the agents’ network. Although not explored at length, the blueprint of a Credit Governance model was created for implementing the new credit monitoring framework inside the telecom firm. The Telecom Company that served as a model for the present work decided to implement the new Credit Monitoring framework after this was presented to its Executive Commission.

Technological evolution

The evolution of a technology and the understanding of the moment in its life cycle is of the utmost importance to the entry strategy devised by any company. Having the entry of EDP Brazil on the micro-generation market as background, the present workproject attempts to summarize the most important topics in management literature concerning the theory of technology life-cycles and the updated literature on developments of photovoltaic technology to infer the current positioning of this technology in the theoretical models. The need for this type of work stems from the very common lack of bridging between the academic research of economic aspects relevant to the evolution of technologies and the agents of research on specific technological issues. When this occurs, namely due to the external nature of research to companies, thereby escaping the harsh economic controls of a profit seeking enterprise, the evolution many times lacks the appropriate framework to be studied on a more forward looking manner and to allow for management decisions to be based on.

Distributed solar micro generation

Taking into account the fact that the sun’s radiation is estimated to be enough to cover 10.000 times the world’s total energy needs (BRAKMANN & ARINGHOFF, 2003), it is difficult to understand how solar photovoltaic systems (PV) are still such a small part of the energy source matrix across the globe. Though there is an ongoing debate as to whether energy consumption leads to economic growth or whether it is the other way around, the two variables appear correlated and it is clear that ensuring the availability of energy to match a country’s growth targets is one of the prime concerns for any government. The topic of centralized vs distributed electricity generation is also approached, especially in what regards the latter fit to developing countries needs, namely the lack of investment capabilities and infrastructure, scattered population, and other factors. Finally, Brazil’s case is reviewed, showing that the current cost of electricity from the grid versus the cost from PV solutions still places an investment of this nature with 9 to 16 years to reach breakeven (from a 25 year panel lifespan), which is too high compared to the required 4 years for most Brazilians. Still, recently passed legislation opened the door, even if unknowingly, to the development of co-owned solar farms, which could reduce the implementation costs by as much as 20% and hence reduce the number of years to breakeven by 3 years.

Understanding impact readiness in Portugal’s social sector and designing a framework for capacity-building for social impact

This project is based on the theme of capacity-building in social organisations to improve their impact readiness, which is the predictability of delivering intended outcomes. All organisations which have a social mission, non-profit or for-profit, will be considered to fall within the social sector for the purpose of this work. The thesis will look at (i) what is impact readiness and what are the considerations for building impact readiness in social organisations, (ii) what is the international benchmark in measuring and building impact readiness, (iii) understand the impact readiness of Portuguese social organisations and the supply of capacity building for social impact in Portugal currently, and (iv) provide recommendations on the design of a framework for capacity building for impact readiness adapted to the Portuguese context. This work is of particular relevance to the Social Investment Laboratory, which is a sponsor of this project, in its policy work as part of the Portuguese Social Investment Taskforce (the “Taskforce”). This in turn will inform its contribution to the set-up of Portugal Inovação Social, a wholesaler catalyst entity of social innovation and social investment in the country, launched in early 2015. Whilst the output of this work will be set a recommendations for wider application for capacity-building programmes in Portugal, Portugal Inovação Social will also clearly have a role in coordinating the efforts of market players – foundations, corporations, public sector and social organisations – in implementing these recommendations. In addition, the findings of this report could have relevance to other countries seeking to design capacity building frameworks in their local markets and to any impact-driven organisations with an interest in enhancing the delivery of impact within their work.
