Advances in upper limb stroke rehabilitation: a technology push

Strokes affect thousands of people worldwide leaving sufferers with severe disabilities affecting their daily activities. In recent years, new rehabilitation techniques have emerged such as constraint-induced therapy, biofeedback therapy and robot-aided therapy. In particular, robotic techniques allow precise recording of movements and application of forces to the affected limb, making it a valuable tool for motor rehabilitation. In addition, robot-aided therapy can utilise visual cues conveyed on a computer screen to convert repetitive movement practice into an engaging task such as a game. Visual cues can also be used to control the information sent to the patient about exercise performance and to potentially address psychosomatic variables influencing therapy. This paper overviews the current state-of-the-art on upper limb robot-mediated therapy with a focal point on the technical requirements of robotic therapy devices leading to the development of upper limb rehabilitation techniques that facilitate reach-to-touch, fine motor control, whole-arm movements and promote rehabilitation beyond hospital stay. The reviewed literature suggest that while there is evidence supporting the use of this technology to reduce functional impairment, besides the technological push, the challenge ahead lies on provision of effective assessment of outcome and modalities that have a stronger impact transferring functional gains into functional independence.

Case studies for contract-based systems

Of the ways in which agent behaviour can be regulated in a multiagent system, electronic contracting – based on explicit representation of different parties' responsibilities, and the agreement of all parties to them – has significant potential for modern industrial applications. Based on this assumption, the CONTRACT project aims to develop and apply electronic contracting and contract-based monitoring and verification techniques in real world applications. This paper presents results from the initial phase of the project, which focused on requirements solicitation and analysis. Specifically, we survey four use cases from diverse industrial applications, examine how they can benefit from an agent-based electronic contracting infrastructure and outline the technical requirements that would be placed on such an infrastructure. We present the designed CONTRACT architecture and describe how it may fulfil these requirements. In addition to motivating our work on the contract-based infrastructure, the paper aims to provide a much needed community resource in terms of use case themselves and to provide a clear commercial context for the development of work on contract-based system.

Parcelamento do solo, a necessidade de uniformizar alguns padrões de projetos das vias urbanas

Este trabalho faz uma análise da legislação sobre o parcelamento do solo nas diferentes instâncias de Governo. São analisadas as diversidades e contradições das leis municipais de parcelamento do solo de onze prefeituras estrategicamente distribuídas no Estado. A análise foca em particular o tratamento da hierarquia viária; as dimensões dos gabaritos viários; as rampas empregadas; o comprimento máximo dos quarteirões nos loteamentos residenciais em função da testada mínima dos lotes e a concordância vertical nas interseções. São analisados também os requisitos técnicos de projeto geométrico de vias urbanas estabelecidas por Órgãos federais e estaduais. A revisão bibliográfica aborda questões fundamentais na urbanização tais como os pedestres, as interseções e a capacidade das vias urbanas, com o propósito de sustentar a proposição de alterações nos requisitos técnicos preconizados pelas legislações sobre o parcelamento do solo urbano. Suprindo lacuna constatada na legislação municipal sobre o parcelamento do solo e, fundamentado em simulação gráfica com veículo de transporte coletivo urbano, o trabalho apresenta tabela com sugestões para o tratamento de curvas verticais nas interseções das vias urbanas nos loteamentos. Com as informações obtidas da análise da legislação, na pesquisa bibliográfica e dos requisitos técnicos constantes nas normas conhecidas, propõe-se dimensões para vias urbanas, comprimento ideal para quarteirões residenciais, valores de taxas de declividade urbana e formas de executar-se a concordância destas rampas nas interseções. Com os valores planimétricos sugeridos fez-se um parcelamento em gleba fictícia e comparou-se os resultados com outros loteamentos projetados na mesma gleba utilizando-se as prescrições das leis municipais estudadas.

Informatização da operação e da gestão de uma unidade de saúde de alta complexidade do sistema único de saúde (SUS): estudo de caso do instituto de medicina integral Prof. Fernando Figueira (Imip) sob o enfoque do isomorfismo institucional

O trabalho buscou identificar e avaliar a escolha do Imip à luz da teoria neoinstitucional, mediante os mecanismos isomórficos que caracterizam o campo das organizações de saúde. Trata-se de um estudo de caso, tendo o Imip como objeto de análise, voltado especificamente para dois modelos de informatização da operação e da gestão, a fim de verificar qual o mais adequado para as especificidades da instituição, incluindo o aspecto financeiro, custo/benefício. O primeiro modelo se refere a um sistema próprio de informatização; o segundo a um modelo de sistema de gestão já existente, comercializado por empresa especializada nesta tecnologia. A metodologia abrangeu pesquisas bibliográficas, documentais e de campo. O referencial teórico foi a teoria neoinstitucional e o trabalho de campo constou de uma pesquisa incluindo observação simples, visando compor variáveis dos dois modelos avaliados, e coleta de dados realizada por meio da aplicação de dois questionários: um questionário aberto, com os dirigentes do Imip, e um questionário misto, com cem colaboradores, utilizadores do sistema, escolhidos aleatoriamente, por sorteio. Entre os achados se identificou claras referências ao isomorfismo, principalmente o mimético, nas percepções dos indivíduos respondentes. Ao final da pesquisa, foi possível concluir que a contratação de um sistema de gestão hospitalar, já existente no mercado, concebido e comercializado por empresa de tecnologia especializada no segmento da saúde, justificou-se como a melhor escolha para a organização, pois, as semelhanças existentes entre os processos do Instituto e aqueles contidos no sistema eram muito mais relevantes que suas particularidades. Outro fator relevante levou em consideração os elevados custos para uma única instituição desenvolver e manter sozinha um sistema atualizado segundo as exigências normativas e técnicas necessárias às organizações de saúde e os padrões de qualidade da informação estabelecidos pelo SUS.

Efeito da adição de argila expandida e adições minerais na formulação de concretos estruturais leves autoadensáveis

The search for alternative materials with lower density, reduction in heat transfer and propagation of noise associated with the ease of handling and application in concrete structures, represents an enormous challenge in the formulation and knowledge of the performance of self-compacting lightweight concrete, which has technology little known nationally, and appears on the international scene as an innovative material and alternative to conventional concrete. Based on these, this study set out to study self-compacting lightweight concrete made with two distinct grades of expanded clay associated with the addition of plasticizing/superplasticizers additives and mineral additions of metakaolin and bagasse ash of sugar cane. There is also an object of study, evaluation of pozzolanic activity of mineral admixtures and their influence on the durability characteristics of concrete. The rheological, physical, mechanical and microstructural analysis in this study served as basis in the classification of concretes autoadensáveis, targeting the national technical requirements for their classification in the category autoadensável and lightweight structural. The inclusion of mineral admixtures (metakaolin and bagasse ash of sugar cane), partial replacement of cement, pozzolanic activity and demonstrated maintenance of mechanical properties through the filler effect, a reduction of up to 76% of the nitrogen gas permeability in blend with 20% bagasse ash. All concretes had rheology (cohesion and consistency) suitable for self-adensability as well as strength and density inherent structural lightweight concrete without presenting phenomena of segregation and exudation

The Evidence of the Rugoscopy Effectiveness as a Human Identification Method in Patients Submitted to Rapid Palatal Expansion

The objective of this study was to demonstrate the effectiveness of rugoscopy as a human identification method, even when the patient is submitted to rapid palatal expansion, which in theory would introduce doubt. With this intent, the Rugoscopic Identity was obtained for each subject using the classification formula proposed by Santos based on the intra-oral casts made before and after treatment from patients who were subjected to palatal expansion. The casts were labeled with the patients' initials and randomly arranged for studying. The palatine rugae kept the same patterns in every case studied. The technical error of the intra-evaluator measurement provided a confidence interval of 95%, making rugoscopy a reliable identification method for patients who were submitted to rapid palatal expansion, because even in the presence of intra-oral changes owing to the use of palatal expanders, the palatine rugae retained the biological and technical requirements for the human identification process. © 2012 American Academy of Forensic Sciences.

Relações inter-firmas em Barcarena/PA: um estudo das práticas de inovação e cooperação na rede de fornecedores e subcontratados da IRCC

Este trabalho tem como objetivo apresentar um estudo das relações inter-firmas estabelecidas entre empresas mínero-metalúrgicas localizadas no distrito industrial do município de Barcarena, no estado do Pará, a partir da análise das interações entre uma empresa central e sua rede de fornecedores e subcontratados, que operacionalizam o beneficiamento e a exportação do mineral conhecido como caulim. Segundo as abordagens teóricas que defendem a ocorrência e a disseminação de inovações tecnológicas como base para o desenvolvimento econômico, realizou-se um estudo sobre a forma como os arranjos produtivos são capazes de gerar e manter vantagens competitivas a partir de sistemas de inovação baseados em redes cooperativas integradas por um grupo específico de agentes públicos e privados. Os resultados da pesquisa mostram que, em que pese a existência de inovações nos processos produtivos, em função das exigências técnicas apresentadas por seus contratantes, as empresas subcontratadas, via de regra, não conseguem estabelecer relações de cooperação capazes de promover a disseminação destas inovações, assim como também geralmente não dispõem de recursos gerenciais e tecnológicos capazes de gerar inovações de produtos ou de transformar as inovações de processos em significativos ganhos de produtividade. A ausência de cooperação entre as empresas estende-se aos relacionamentos com os outros agentes, tais como instituições de ensino e pesquisa, de treinamento e capacitação técnica, órgãos de fomento e crédito, associações, cooperativas e sindicatos. Conseqüentemente, a rede de subcontratação desperdiça o potencial de ganhos sinérgicos capazes de elevar os patamares de competitividade local. Abordam-se também as implicações do estudo para a pesquisa, para o desenvolvimento local e para o planejamento e as políticas públicas.

Levantamento para a implantação de um sistema de gestão da qualidade segundo a norma NBR ISO/IEC 17025:2005 no Laboratório de celulose e papel da UNESP-Itapeva

The aim of this study is to perform a situational analysis of the Laboratory of pulp and paper-UNESP ITAPEVA for conducting proposal the accreditation according to ISO / IEC 17025:2005. The ISO / IEC 17025 establishes the criteria for those laboratories wishing to demonstrate their technical competence, which have an effective quality system and are able to generate technically valid results, establishing a single international standard for certifying the competence of laboratories to carry tests and / or calibrations, including sampling. The case study was conducted on laboratory Pulp and Paper Universidade Estadual Paulista (UNESP), campus Itapeva, where we compared the views of the technician responsible for the laboratory and a regular user. The generated conclusion is that the laboratory is unable to initiate an accreditation process, because it fails the requirements such as quality manual, register of subcontractors, research of customer satisfaction, schedule of internal audits, schedule for completion of critical analysis, profile of the functions required, functions current description, documentation of technical requirements for accommodation and environmental conditions, calibration programs, equipment calibration program, programs calibration standards and reports and / or certificate of test and / or calibration, that are in accordance with ISO / IEC 17025:2005, beyond that there is not the possibility to develop and implement a quality system without the commitment of everyone involved, regardless of the functional hierarchy

CRITICAL APPLICATIONS OF SW 846 US EPA METHODS TO EVALUATION OF MARINE SAMPLES QUALITY

Technical evaluation of analytical data is of extreme relevance considering it can be used for comparisons with environmental quality standards and decision-making as related to the management of disposal of dredged sediments and the evaluation of salt and brackish water quality in accordance with CONAMA 357/05 Resolution. It is, therefore, essential that the project manager discusses the environmental agency`s technical requirements with the laboratory contracted for the follow-up of the analysis underway and even with a view to possible re-analysis when anomalous data are identified. The main technical requirements are: (1) method quantitation limits (QLs) should fall below environmental standards; (2) analyses should be carried out in laboratories whose analytical scope is accredited by the National Institute of Metrology (INMETRO) or qualified or accepted by a licensing agency; (3) chain of custody should be provided in order to ensure sample traceability; (4) control charts should be provided to prove method performance; (5) certified reference material analysis or, if that is not available, matrix spike analysis, should be undertaken and (6) chromatograms should be included in the analytical report. Within this context and with a view to helping environmental managers in analytical report evaluation, this work has as objectives the discussion of the limitations of the application of SW 846 US EPA methods to marine samples, the consequences of having data based on method detection limits (MDL) and not sample quantitation limits (SQL), and present possible modifications of the principal method applied by laboratories in order to comply with environmental quality standards.

Feasibility study of performing high precision gamma spectroscopy of lambda lambda hypernuclei in the PANDA experiment

Hypernuclear physics is currently attracting renewed interest, due tornthe important role of hypernuclei spectroscopy rn(hyperon-hyperon and hyperon-nucleon interactions) rnas a unique toolrnto describe the baryon-baryon interactions in a unified way and to rnunderstand the origin of their short-range.rnrnHypernuclear research will be one of the main topics addressed by the {sc PANDA} experimentrnat the planned Facility for Antiproton and Ion Research {sc FAIR}.rnThanks to the use of stored $overline{p}$ beams, copiousrnproduction of double $Lambda$ hypernuclei is expected at thern{sc PANDA} experiment, which will enable high precision $gamma$rnspectroscopy of such nuclei for the first time.rnAt {sc PANDA} excited states of $Xi^-$ hypernuclei will be usedrnas a basis for the formation of double $Lambda$ hypernuclei.rnFor their detection, a devoted hypernuclear detector setup is planned. This setup consists ofrna primary nuclear target for the production of $Xi^{-}+overline{Xi}$ pairs, a secondary active targetrnfor the hypernuclei formation and the identification of associated decay products and a germanium array detector to perform $gamma$ spectroscopy.rnrnIn the present work, the feasibility of performing high precision $gamma$rnspectroscopy of double $Lambda$ hypernuclei at the {sc PANDA} experiment has been studiedrnby means of a Monte Carlo simulation. For this issue, the designing and simulation of the devoted detector setup as well as of the mechanism to produce double $Lambda$ hypernuclei have been optimizedrntogether with the performance of the whole system. rnIn addition, the production yields of double hypernuclei in excitedrnparticle stable states have been evaluated within a statistical decay model.rnrnA strategy for the unique assignment of various newly observed $gamma$-transitions rnto specific double hypernuclei has been successfully implemented by combining the predicted energy spectra rnof each target with the measurement of two pion momenta from the subsequent weak decays of a double hypernucleus.rn% Indeed, based on these Monte Carlo simulation, the analysis of the statistical decay of $^{13}_{Lambda{}Lambda}$B has been performed. rn% As result, three $gamma$-transitions associated to the double hypernuclei $^{11}_{Lambda{}Lambda}$Bern% and to the single hyperfragments $^{4}_{Lambda}$H and $^{9}_{Lambda}$Be, have been well identified.rnrnFor the background handling a method based on time measurement has also been implemented.rnHowever, the percentage of tagged events related to the production of $Xi^{-}+overline{Xi}$ pairs, variesrnbetween 20% and 30% of the total number of produced events of this type. As a consequence, further considerations have to be made to increase the tagging efficiency by a factor of 2.rnrnThe contribution of the background reactions to the radiation damage on the germanium detectorsrnhas also been studied within the simulation. Additionally, a test to check the degradation of the energyrnresolution of the germanium detectors in the presence of a magnetic field has also been performed.rnNo significant degradation of the energy resolution or in the electronics was observed. A correlationrnbetween rise time and the pulse shape has been used to correct the measured energy. rnrnBased on the present results, one can say that the performance of $gamma$ spectroscopy of double $Lambda$ hypernuclei at the {sc PANDA} experiment seems feasible.rnA further improvement of the statistics is needed for the background rejection studies. Moreover, a more realistic layout of the hypernuclear detectors has been suggested using the results of these studies to accomplish a better balance between the physical and the technical requirements.rn

Mathematical Optimization Applied to Thermal and Electrical Energy Systems

This Thesis aims at building and discussing mathematical models applications focused on Energy problems, both on the thermal and electrical side. The objective is to show how mathematical programming techniques developed within Operational Research can give useful answers in the Energy Sector, how they can provide tools to support decision making processes of Companies operating in the Energy production and distribution and how they can be successfully used to make simulations and sensitivity analyses to better understand the state of the art and convenience of a particular technology by comparing it with the available alternatives. The first part discusses the fundamental mathematical background followed by a comprehensive literature review about mathematical modelling in the Energy Sector. The second part presents mathematical models for the District Heating strategic network design and incremental network design. The objective is the selection of an optimal set of new users to be connected to an existing thermal network, maximizing revenues, minimizing infrastructure and operational costs and taking into account the main technical requirements of the real world application. Results on real and randomly generated benchmark networks are discussed with particular attention to instances characterized by big networks dimensions. The third part is devoted to the development of linear programming models for optimal battery operation in off-grid solar power schemes, with consideration of battery degradation. The key contribution of this work is the inclusion of battery degradation costs in the optimisation models. As available data on relating degradation costs to the nature of charge/discharge cycles are limited, we concentrate on investigating the sensitivity of operational patterns to the degradation cost structure. The objective is to investigate the combination of battery costs and performance at which such systems become economic. We also investigate how the system design should change when battery degradation is taken into account.

How to Improve the Production Process for interactive TV with semi-formal Methods

The central question for this paper is how to improve the production process by closing the gap between industrial designers and software engineers of television(TV)-based User Interfaces (UI) in an industrial environment. Software engineers are highly interested whether one UI design can be converted into several fully functional UIs for TV products with different screen properties. The aim of the software engineers is to apply automatic layout and scaling in order to speed up and improve the production process. However, the question is whether a UI design lends itself for such automatic layout and scaling. This is investigated by analysing a prototype UI design done by industrial designers. In a first requirements study, industrial designers had created meta-annotations on top of their UI design in order to disclose their design rationale for discussions with software engineers. In a second study, five (out of ten) industrial designers assessed the potential of four different meta-annotation approaches. The question was which annotation method industrial designers would prefer and whether it could satisfy the technical requirements of the software engineering process. One main result is that the industrial designers preferred the method they were already familiar with, which therefore seems to be the most effective one although the main objective of automatic layout and scaling could still not be achieved.

Produktentwicklung von Druckgussteilen

Die Produktentwicklung von Druckgussteilen kann flexibel, wirtschaftlich und schnell durch die Herstellung von RP-Unikaten und Metallabgüssen aus Keramikschalen realisiert werden. Dieser Weg eignet sich vor allem für komplexe Bauteile und macht eine Produkterprobung mit qualitativ deutlich verbesserter Aussagekraft trotz reduzierter Entwicklungskosten möglich. In Abgrenzung zum Sandguss, muss die Konstruktion der Bauteile nicht verändert werden. 
Durch eine gezielte Wärmebehandlung wird die Vergleichbarkeit der mechanischen Eigenschaften von Prototypen zu späteren Serienteilen möglich. Technisch sinnvolle Änderungen sind leicht und flexibel realisierbar, da werkzeuglos gefertigt wird. Für unerreichbare Hohlräume und Hinterschnitte kann in diesem Verfahren mit Keramikkernen als Einleger gearbeitet werden. Auch diese Kerne können werkzeuglos hergestellt werden. Ein Verzicht auf technisch Sinnvolles aus Kostengründen ist damit hinfällig.
In der Konstruktion ergeben sich neue Freiheitsgrade, so dass Ziele im Leichtbau, die Einsparung von Verbindungstechnik oder die erhöhte Materialeffizienz realisierbar werden. Die so entwickelten Bauteile sind insgesamt qualitativ hochwertiger und bilden die technischen Anforderungen bestmöglich ab. Damit kann die für die Erprobung benötigte Zahl der Prototypen verringert werden. 
Je komplexer die Geometrie der Bauteile, je stärker kommen die beschriebenen Effekte zum Tragen. Diese Aussage gilt für die Produktentwicklung und für Kleinserien, die herkömmlich zu teuer und zu schwer im Druckguss oder Schmiedeverfahren produziert werden
