Managed Acceleration for In-Memory Database Analytic Workloads

In-Memory Databases (IMDBs), such as SAP HANA, enable new levels of database performance by removing the disk bottleneck and by compressing data in memory. The consequence of this improved performance means that reports and analytic queries can now be processed on demand. Therefore, the goal is now to provide near real-time responses to compute and data intensive analytic queries. To facilitate this, much work has investigated the use of acceleration technologies within the database context. While current research into the application of these technologies has yielded positive results, they have tended to focus on single database tasks or on isolated single user requests. This paper uses SHEPARD, a framework for managing accelerated tasks across shared heterogeneous resources, to introduce acceleration into an IMDB. Results show how, using SHEPARD, multiple simultaneous user queries all receive speed-up by using a shared pool of accelerators. Results also show that offloading analytic tasks onto accelerators can have indirect benefits for other database workloads by reducing contention for CPU resources.

Comunicação organizacional e identidade colectiva num agrupamento de escolas

O reforço e a diversificação do investimento na comunicação por parte das instituições educativas são discutidos neste estudo como uma das consequências da nova gestão pública. Tendo em vista a ‘qualidade’ e a ‘eficácia’ das suas prestações, as escolas têm procurado tornar-se mais dialogantes, assumindo a aposta na comunicação organizacional como parte integrante de uma estratégia empreendedora, que lhes tem vindo a conferir uma nova identidade colectiva unificada em torno dos valores neoliberais. Não obstante, os sistemas de comunicação criados são mais complexos do que se poderia supor. Revelando a influência de pressões híbridas, estes sistemas transformaram-se num contexto mediador da mudança embutido em novas concepções de escola e dos novos mandatos para a educação (assim legitimados interna e externamente), surgindo, ao mesmo tempo, como o locus de produção de novas identidades. Tal acontece porque a comunicação constitui o ponto de convergência entre as diferentes políticas educativas e as práticas localmente adoptadas na sequência de um processo de interpretação criativa das diferentes pressões. É este o sentido com que afirmamos que a comunicação se constitui numa meta-ideia ao serviço da ‘qualidade’, ainda que esta possa ser perspectivada a partir do ideal burocrático da organização (como sinónimo de eficiência administrativa), do ideal profissional (centrada no processo de ensino-aprendizagem) ou do ideal empreendedor (valorizando a capacidade de resposta às solicitações do mercado). Os dados empíricos, que sustentaram o nosso estudo, resultaram da observação do quotidiano de um agrupamento de escolas do ensinobásico e dos testemunhos recolhidos, ao longo de três anos, nesta comunidade educativa. Recorrendo ao estudo de caso como estratégia de investigação enveredámos inicialmente, num contexto de descoberta, pela realização de observações ‘desarmadas e naturais’. Usámos, posteriormente, a análise documental, a entrevista e o questionário na recolha de informação complementar, o que, mediante o cruzamento de métodos de análise qualitativa e quantitativa, nos permitiu tirar partido da triangulação dos dados. Os resultados obtidos apontam para a centralidade dos processos de comunicação na transformação induzida pela nova gestão pública e para o desenvolvimento de uma matriz discursiva bilinguista, que procura harmonizar os imperativos de ‘mercado’ com o discurso pedagógico e com modelos burocrático-profissionais de organização.

Desenvolvimento local: estratégias e competitividade

O tema desta tese relaciona-se com a qualificação das estratégias de desenvolvimento municipais. A emergência do planeamento territorial estratégico, como alternativa ou suplemento ao planeamento físico tradicional, reintroduziu o debate sobre a capacidade de o planeamento territorial influenciar trajectórias de desenvolvimento descentralizadas. A investigação segue, em termos teóricos e empíricos, duas linhas de inquirição: uma, relativa aos desafios colocados pelas premissas metodológicas e operativas da abordagem estratégica em planeamento territorial; a outra, diz respeito às implicações da actualização da agenda que acompanharam a emergência da abordagem estratégica, incidindo designadamente sobre a questão da competitividade territorial. A primeira lida com a validade intrínseca da abordagem estratégica e a forma como esta confronta as práticas tradicionais dominantes no planeamento territorial, em particular em Portugal. É feita uma análise do debate e dos resultados de experiências recentes em planeamento territorial estratégico e uma reflexão sobre a forma como estas podem influenciar o estabelecimento de novos referenciais para a intervenção dos sistemas de planeamento. A segunda pretende aprofundar o conhecimento sobre as competências necessárias ao planeamento, para a gestão de processos descentralizados de promoção da competitividade, e avaliar o alcance dos resultados obtidos até agora e as limitações associadas à concretização daquele objectivo. Argumenta-se que algumas das mais significativas exigências conceptuais da perspectiva estratégica de intervenção sobre o território são tratadas com ligeireza, ao mesmo tempo que, no contexto da definição de um quadro de avaliação do planeamento territorial estratégico, se espera contribuir para uma reavaliação do papel que cabe ao plano, enquanto instrumento de referência e de motivação para a acção em planeamento. Na outra parte da investigação, relativa à actualização da agenda de planeamento, é feita uma análise crítica da noção de competitividade Territorial. Usando contributos disciplinares da economia regional, da geografia económica, da sociologia económica e dos sistemas territoriais de inovação desenvolve-se um quadro conceptual que procura pôr em evidência a convergência entre as capacidades de uma prática qualificada de planeamento territorial estratégico e as necessidades e requisitos dos processos de desenvolvimento local. A análise de um conjunto de experiências municipais de concepção e implementação de planos estratégicos, representando realidades locais bastante heterogéneas em termos de dinâmica económica e de capacidades institucionais, é usada para avaliar alguns dos principais aspectos levantados em cada uma das linhas sob investigação.

Enhanced ethernet switching technology for adaptive hard real-time applications: Tecnologia de comutação ethernet melhorada para aplicações adaptativas e críticas de tempo-real

Os Sistemas Embarcados Distribuídos (SEDs) estão, hoje em dia, muito difundidos em vastas áreas, desde a automação industrial, a automóveis, aviões, até à distribuição de energia e protecção do meio ambiente. Estes sistemas são, essencialmente, caracterizados pela integração distribuída de aplicações embarcadas, autónomas mas cooperantes, explorando potenciais vantagens em termos de modularidade, facilidade de manutenção, custos de instalação, tolerância a falhas, entre outros. Contudo, o ambiente operacional onde se inserem estes tipos de sistemas pode impor restrições temporais rigorosas, exigindo que o sistema de comunicação subjacente consiga transmitir mensagens com garantias temporais. Contudo, os SEDs apresentam uma crescente complexidade, uma vez que integram subsistemas cada vez mais heterogéneos, quer ao nível do tráfego gerado, quer dos seus requisitos temporais. Em particular, estes subsistemas operam de forma esporádica, isto é, suportam mudanças operacionais de acordo com estímulos exteriores. Estes subsistemas também se reconfiguram dinamicamente de acordo com a actualização dos seus requisitos e, ainda, têm lidar com um número variável de solicitações de outros subsistemas. Assim sendo, o nível de utilização de recursos pode variar e, desta forma, as políticas de alocação estática tornam-se muito ineficientes. Consequentemente, é necessário um sistema de comunicação capaz de suportar com eficácia reconfigurações e adaptações dinâmicas. A tecnologia Ethernet comutada tem vindo a emergir como uma solução sólida para fornecer comunicações de tempo-real no âmbito dos SEDs, como comprovado pelo número de protocolos de tempo-real que foram desenvolvidos na última década. No entanto, nenhum dos protocolos existentes reúne as características necessárias para fornecer uma eficiente utilização da largura de banda e, simultaneamente, para respeitar os requisitos impostos pelos SEDs. Nomeadamente, a capacidade para controlar e policiar tráfego de forma robusta, conjugada com suporte à reconfiguração e adaptação dinâmica, não comprometendo as garantias de tempo-real. Esta dissertação defende a tese de que, pelo melhoramento dos comutadores Ethernet para disponibilizarem mecanismos de reconfiguração e isolamento de tráfego, é possível suportar aplicações de tempo-real críticas, que são adaptáveis ao ambiente onde estão inseridas.Em particular, é mostrado que as técnicas de projecto, baseadas em componentes e apoiadas no escalonamento hierárquico de servidores de tráfego, podem ser integradas nos comutadores Ethernet para alcançar as propriedades desejadas. Como suporte, é fornecida, também, uma solução para instanciar uma hierarquia reconfigurável de servidores de tráfego dentro do comutador, bem como a análise adequada ao modelo de escalonamento. Esta última fornece um limite superior para o tempo de resposta que os pacotes podem sofrer dentro dos servidores de tráfego, com base unicamente no conhecimento de um dado servidor e na hierarquia actual, isto é, sem o conhecimento das especifidades do tráfego dentro dos outros servidores. Finalmente, no âmbito do projecto HaRTES foi construído um protótipo do comutador Ethernet, o qual é baseado no paradigma “Flexible Time-Triggered”, que permite uma junção flexível de uma fase síncrona para o tráfego controlado pelo comutador e uma fase assíncrona que implementa a estrutura hierárquica de servidores referidos anteriormente. Além disso, as várias experiências práticas realizadas permitiram validar as propriedades desejadas e, consequentemente, a tese que fundamenta esta dissertação.

Control design for multicast-aware class-based networks

The expectations of citizens from the Information Technologies (ITs) are increasing as the ITs have become integral part of our society, serving all kinds of activities whether professional, leisure, safety-critical applications or business. Hence, the limitations of the traditional network designs to provide innovative and enhanced services and applications motivated a consensus to integrate all services over packet switching infrastructures, using the Internet Protocol, so as to leverage flexible control and economical benefits in the Next Generation Networks (NGNs). However, the Internet is not capable of treating services differently while each service has its own requirements (e.g., Quality of Service - QoS). Therefore, the need for more evolved forms of communications has driven to radical changes of architectural and layering designs which demand appropriate solutions for service admission and network resources control. This Thesis addresses QoS and network control issues, aiming to improve overall control performance in current and future networks which classify services into classes. The Thesis is divided into three parts. In the first part, we propose two resource over-reservation algorithms, a Class-based bandwidth Over-Reservation (COR) and an Enhanced COR (ECOR). The over-reservation means reserving more bandwidth than a Class of Service (CoS) needs, so the QoS reservation signalling rate is reduced. COR and ECOR allow for dynamically defining over-reservation parameters for CoSs based on network interfaces resource conditions; they aim to reduce QoS signalling and related overhead without incurring CoS starvation or waste of bandwidth. ECOR differs from COR by allowing for optimizing control overhead minimization. Further, we propose a centralized control mechanism called Advanced Centralization Architecture (ACA), that uses a single state-full Control Decision Point (CDP) which maintains a good view of its underlying network topology and the related links resource statistics on real-time basis to control the overall network. It is very important to mention that, in this Thesis, we use multicast trees as the basis for session transport, not only for group communication purposes, but mainly to pin packets of a session mapped to a tree to follow the desired tree. Our simulation results prove a drastic reduction of QoS control signalling and the related overhead without QoS violation or waste of resources. Besides, we provide a generic-purpose analytical model to assess the impact of various parameters (e.g., link capacity, session dynamics, etc.) that generally challenge resource overprovisioning control. In the second part of this Thesis, we propose a decentralization control mechanism called Advanced Class-based resource OverpRovisioning (ACOR), that aims to achieve better scalability than the ACA approach. ACOR enables multiple CDPs, distributed at network edge, to cooperate and exchange appropriate control data (e.g., trees and bandwidth usage information) such that each CDP is able to maintain a good knowledge of the network topology and the related links resource statistics on real-time basis. From scalability perspective, ACOR cooperation is selective, meaning that control information is exchanged dynamically among only the CDPs which are concerned (correlated). Moreover, the synchronization is carried out through our proposed concept of Virtual Over-Provisioned Resource (VOPR), which is a share of over-reservations of each interface to each tree that uses the interface. Thus, each CDP can process several session requests over a tree without requiring synchronization between the correlated CDPs as long as the VOPR of the tree is not exhausted. Analytical and simulation results demonstrate that aggregate over-reservation control in decentralized scenarios keep low signalling without QoS violations or waste of resources. We also introduced a control signalling protocol called ACOR Protocol (ACOR-P) to support the centralization and decentralization designs in this Thesis. Further, we propose an Extended ACOR (E-ACOR) which aggregates the VOPR of all trees that originate at the same CDP, and more session requests can be processed without synchronization when compared with ACOR. In addition, E-ACOR introduces a mechanism to efficiently track network congestion information to prevent unnecessary synchronization during congestion time when VOPRs would exhaust upon every session request. The performance evaluation through analytical and simulation results proves the superiority of E-ACOR in minimizing overall control signalling overhead while keeping all advantages of ACOR, that is, without incurring QoS violations or waste of resources. The last part of this Thesis includes the Survivable ACOR (SACOR) proposal to support stable operations of the QoS and network control mechanisms in case of failures and recoveries (e.g., of links and nodes). The performance results show flexible survivability characterized by fast convergence time and differentiation of traffic re-routing under efficient resource utilization i.e. without wasting bandwidth. In summary, the QoS and architectural control mechanisms proposed in this Thesis provide efficient and scalable support for network control key sub-systems (e.g., QoS and resource control, traffic engineering, multicasting, etc.), and thus allow for optimizing network overall control performance.

La parole en action : dissensus sur les accommodements raisonnables lors des auditions en commission parlementaire au Québec (2010-2011)

La question du pluralisme religieux est au Québec, l’objet de désaccords et de variations dans son mode de régulation et ses instruments d’action publique. La consultation publique sur le projet loi n° 94, Loi établissant les balises encadrant les demandes d’accommodement dans l’Administration gouvernementale et dans certains établissements, est au cœur de ceux-ci. En se basant sur l’analyse des séances d’auditions publiques en commission parlementaire qui ont eu lieu au Québec entre mai 2010 et janvier 2011 sur le projet de loi n° 94, cette thèse vise à interroger les enjeux liés à la publicisation des prises de positions et de l’échange d’arguments entre différents acteurs. À partir d’une méthodologie par théorisation enracinée et d’un cadre conceptuel qui se rattache à la communication publique, cette thèse cherche à mettre en évidence quelques-unes des propriétés des interactions verbales et non verbales qui composent et incarnent cette activité délibérative. Elle approche ces interactions du point de vue de leur publicisation en s’appuyant sur deux principes : la participation publique en tant qu’un instant de la construction du problème public et l’audition publique en commission parlementaire comme maillon d’un réseau dialogique qui participe à la publicisation du désaccord sur les accommodements raisonnables. Mettant l’accent sur l’usage du langage (verbal, non verbal et para verbal), l’objectif de cette thèse est de mieux comprendre comment des groupes minoritaires et majoritaires, engagés dans une arène publique où les points de vue par rapport aux accommodements raisonnables sont confrontés et mis en visibilité, gèrent leur situation de parole publique. La démarche de recherche a combiné deux stratégies d’analyse : la première stratégie d’inspiration conversationnelle, qui observe chaque séquence comme objet indépendant, a permis de saisir le déroulement des séances d’audition en respectant le caractère séquentiel des tours de parole La deuxième stratégie reviens sur les principaux résultats de l’analyse des séances d’auditions pour valider les résultats et parvenir à la saturation théorique pour élaborer une modélisation. L’exploitation des données selon cette approche qualitative a abouti au repérage de trois dynamiques. La première fait état des contraintes discursives. La seconde met en évidence le rôle des dimensions motivationnelles et socioculturelles dans la construction des positionnements et dans l’adoption d’un registre polémique. La troisième souligne la portée de la parole publique en termes d’actualisation des rapports de pouvoir et de confirmation de son caractère polémique. La modélisation proposée par cette thèse représente le registre polémique comme un élément constitutif de l’engagement argumentatif des acteurs sociaux mais qui est considérablement enchâssé dans d’autres éléments contextuels et motivationnels qui vont orienter sa portée. En tant qu’elle est exprimée dans un site dialogique, la parole publique en situation d’audition publique en commission parlementaire est en mesure de créer de nouvelles intrigues et d’une possibilité de coexister dans le dissensus. Le principal apport de cette thèse est qu’elle propose une articulation, concrète et originale entre une approche de la parole publique en tant que révélatrice d’autre chose que d’elle-même (nécessaire à tout éclaircissement des points de vue dans cette controverse) et une approche de la parole publique en tant que performance conduisant à la transformation du monde social. D’où, le titre de la thèse : la parole en action. Mots clefs : parole publique, discours, arène publique, pluralisme religieux, accommodements raisonnables, controverses, dissensus, théorisation enracinée

Enhancing Student Learning Experiences in Sport Psychology Modules Using Practical Activities

The University of Worcester states in its most recent strategic plan (2013 – 2018) a set of enduring values that guide and direct the activities of the institution. The first listed, and perhaps the most important value is the striving to be “an outstanding university at which to be a student”. This is further supplemented by values such as “to inspire our students to reach their full potential through excellent, innovative teaching, scholarship and research” (University of Worcester 2013: p.4). One of the many ways in which the institution strives to provide this outstanding educational experience is through regular engagement, both formal and informal, with students at a number of points in each semester. Regular experiences of collating formal and informal feedback has led to the identification of a common theme amongst Higher National Diploma (HND) students in the Institute of Sport and Exercise Sciences (ISES), where they consistently request ‘more practicals’. The ISES modules however are designed to incorporate a high degree of interaction, practical activities and tasks. This is especially important for those studying at HND level as research suggests differences in learning preferences exist when compared to undergraduate students, the former preferring a more tactile style of learning (Peters et al. 2008). Using an introductory Sport Psychology HND module as an example, practical activities and tasks are fully embedded in the taught sessions to enable contextual links to be made between the learning outcomes and their subsequent use. Examples of these include: a. interviewing athletes to produce a performance profile (Butler & Hardy 1992); b. completing psychometric instruments such as the Competitive State Anxiety Inventory-2 (CSAI-2) to measure competitive anxiety in sport (Martens et al. 1990) and demonstrate data collection and construct measurement; c. performing relaxation interventions on the students to demonstrate how specific techniques (in this instance, decreasing somatic anxiety) might work in practice; d. demonstrating how observational learning facilitates skill acquisition by creating experimental conditions that the students participate in, in teaching a new skill. Nevertheless owing to the students' previously stated on-going requests for more practical activities, it became evident that assumptions about what students consider an effective means of experiential or active learning in the context of sport-related disciplines of study needed to be investigated. This is where the opportunity to undertake an action research project arose, this being a practical method commonly employed in pedagogical enquiry to aid reflection on teaching and assessment practice for the purposes of working towards continuous improvement.

The Development of Environmental Assessment Tools to Support the Creation of Dementia Friendly Care Environments: Innovative Practice

The need for more dementia friendly design in hospitals and other care settings is now widely acknowledged. Working with 26 NHS Trusts in England as part of a Department of Health commissioned programme, The King’s Fund developed a set of overarching design principles and an environmental assessment tool for hospital wards in 2012. Following requests from other sectors, additional tools were developed for hospitals, care homes, health centres and housing with care. The tools have proven to be effective in both disseminating the principles of dementia friendly design and in enabling the case to be made for improvements that have a positive effect on patient outcomes and staff morale. This paper reports on the development,use and review of the environmental assessment tools, including further work that is now being taken forward by The Association for Dementia Studies, University of Worcester.

A multi-agent based approach for intelligent smart grid management

The spread and globalization of distributed generation (DG) in recent years has should highly influence the changes that occur in Electricity Markets (EMs). DG has brought a large number of new players to take action in the EMs, therefore increasing the complexity of these markets. Simulation based on multi-agent systems appears as a good way of analyzing players’ behavior and interactions, especially in a coalition perspective, and the effects these players have on the markets. MASCEM – Multi-Agent System for Competitive Electricity Markets was created to permit the study of the market operation with several different players and market mechanisms. MASGriP – Multi-Agent Smart Grid Platform is being developed to facilitate the simulation of micro grid (MG) and smart grid (SG) concepts with multiple different scenarios. This paper presents an intelligent management method for MG and SG. The simulation of different methods of control provides an advantage in comparing different possible approaches to respond to market events. Players utilize electric vehicles’ batteries and participate in Demand Response (DR) contracts, taking advantage on the best opportunities brought by the use of all resources, to improve their actions in response to MG and/or SG requests.

A study on dynamic state information (DSI) around users for safe urban life

To select each node by devices and by contexts in urban computing, users have to put their plan information and their requests into a computing environment (ex. PDA, Smart Devices, Laptops, etc.) in advance and they will try to keep the optimized states between users and the computing environment. However, because of bad contexts, users may get the wrong decision, so, one of the users’ demands may be requesting the good server which has higher security. To take this issue, we define the structure of Dynamic State Information (DSI) which takes a process about security including the relevant factors in sending/receiving contexts, which select the best during user movement with server quality and security states from DSI. Finally, whenever some information changes, users and devices get the notices including security factors, then an automatic reaction can be possible; therefore all users can safely use all devices in urban computing.

Cyclotech - contribution to solve the Technetium shortage by using low energy medical cyclotrons

This paper presents work in progress, to develop an efficient and economic way to directly produce Technetium 99metastable (99mTc) using low-energy cyclotrons. Its importance is well established and relates with the increased global trouble in delivering 99mTc to Nuclear Medicine Departments relying on this radioisotope. Since the present delivery strategy has clearly demonstrated its intrinsic limits, our group decided to follow a distinct approach that uses the broad distribution of the low energy cyclotrons and the accessibility of Molybdenum 100 (100Mo) as the Target material. This is indeed an important issue to consider, since the system here presented, named CYCLOTECH, it is not based on the use of Highly Enriched (or even Low Enriched) Uranium 235 (235U), so entirely complying with the actual international trends and directives concerning the use of this potential highly critical material. The production technique is based on the nuclear reaction 100Mo (p,2n) 99mTc whose production yields have already been documented. Until this moment two Patent requests have already been submitted (the first at the INPI, in Portugal, and the second at the USPTO, in the USA); others are being prepared for submission on a near future. The object of the CYCLOTECH system is to present 99mTc to Nuclear Medicine radiopharmacists in a routine, reliable and efficient manner that, remaining always flexible, entirely blends with established protocols. To facilitate workflow and Radiation Protection measures, it has been developed a Target Station that can be installed on most of the existing PET cyclotrons and that will tolerate up to 400 μA of beam by allowing the beam to strike the Target material at an adequately oblique angle. The Target Station permits the remote and automatic loading and discharge of the Targets from a carriage of 10 Target bodies. On other hand, several methods of Target material deposition and Target substrates are presented. The object was to create a cost effective means of depositing and intermediate the target material thickness (25 - 100μm) with a minimum of loss on a substrate that is able to easily transport the heat associated with high beam currents. Finally, the separation techniques presented are a combination of both physical and column chemistry. The object was to extract and deliver 99mTc in the identical form now in use in radiopharmacies worldwide. In addition, the Target material is recovered and can be recycled.
