Manoeuvre Based Mission Control System for an Autonomous Surface Vehicle

In this work the mission control and supervision system developed for the ROAZ Autonomous Surface Vehicle is presented. Complexity in mission requirements coupled with flexibility lead to the design of a modular hierarchical mission control system based on hybrid systems control. Monitoring and supervision control for a vehicle such as ROAZ mission is not an easy task using tools with low complexity and yet powerful enough. A set of tools were developed to perform both on board mission control and remote planning and supervision. “ROAZ- Mission Control” was developed to be used in support to bathymetric and security missions performed in river and at seas.

Clinical Learning Environment and Supervision. Development and Validation of the CLES Evaluation Scale

The purpose of the study is: (1) to describe how nursing students' experienced their clinical learning environment and the supervision given by staff nurses working in hospital settings; and (2) to develop and test an evaluation scale of Clinical Learning Environment and Supervision (CLES). The study has been carried out in different phases. The pilot study (n=163) explored the association between the characteristics of a ward and its evaluation as a learning environment by students. The second version of research instrument (which was developed by the results of this pilot study) were tested by an expert panel (n=9 nurse teachers) and test-retest group formed by student nurses (n=38). After this evaluative phase, the CLES was formed as the basic research instrument for this study and it was tested with the Finnish main sample (n=416). In this phase, a concurrent validity instrument (Dunn & Burnett 1995) was used to confirm the validation process of CLES. The international comparative study was made by comparing the Finnish main sample with a British sample (n=142). The international comparative study was necessary for two reasons. In the instrument developing process, there is a need to test the new instrument in some other nursing culture. Other reason for comparative international study is the reflecting the impact of open employment markets in the European Union (EU) on the need to evaluate and to integrate EU health care educational systems. The results showed that the individualised supervision system is the most used supervision model and the supervisory relationship with personal mentor is the most meaningful single element of supervision evaluated by nursing students. The ward atmosphere and the management style of ward manager are the most important environmental factors of the clinical ward. The study integrates two theoretical elements - learning environment and supervision - in developing a preliminary theoretical model. The comparative international study showed that, Finnish students were more satisfied and evaluated their clinical placements and supervision with higher scores than students in the United Kingdom (UK). The difference between groups was statistical highly significant (p= 0.000). In the UK, clinical placements were longer but students met their nurse teachers less frequently than students in Finland. Arrangements for supervision were similar. This research process has produced the evaluation scale (CLES), which can be used in research and quality assessments of clinical learning environment and supervision in Finland and in the UK. CLES consists of 27 items and it is sub-divided into five sub-dimensions. Cronbach's alpha coefficient varied from high 0.94 to marginal 0.73. CLES is a compact evaluation scale and user-friendliness makes it suitable for continuing evaluation.

Monitoring system for small sized photovoltaic power plants

This paper presents a monitoring system devoted to small sized photovoltaic (PV) power plants. The system is characterized by: a high level of integration; a low cost, when compared to the cost of the PV system to be monitored; and an easy installation in the majority of the PV plants with installed power of some kW. The system is able to collect, store, process and display electrical and meteorological parameters that are crucial when monitoring PV facilities. The identification of failures in the PV system and the elaboration of performance analysis of such facilities are other important characteristics of the developed system. The access to the information about the monitored facilities is achieved by using a web application, which was developed with a focus on the mobile devices. In addition, there is the possibility of an integration between the developed monitoring system and the central supervision system of Martifer Solar (a company focused on the development, operation and maintenance of PV systems).

Reconfiguração e desenvolvimento do sistema de controlo de um AGV

O veículo guiado automaticamente (AGV) adquirido pelo Departamento de Engenharia Mecânica (DEM) tem vindo a ficar obsoleto devido ao hardware, que nos dias de hoje começa a dar sinais de falhas bem como falta de peças de substituição, e ao software, sendo o PLC (Programmable Logic Controller) usado muito limitado quanto às suas funções de controlo, ficando as principais tarefas de controlo do AGV a cargo de placas eletrónicas de controlo. Para promover o controlo autónomo do AGV, foi decidido retirar toda a parte de hardware que detinha o controlo do mesmo e passou a ser um novo PLC, com maior capacidade de processamento, a executar todo o tipo de controlo necessário ao funcionamento do mesmo. O hardware considerado apenas incluí, de forma resumida, os motores responsáveis pelo movimento e direção, placa de controlo de potência dos motores, placa de interface entre as saídas digitais do PLC e as entradas da placa de controlo de potência dos motores e os demais sensores necessários à deteção de obstáculos, fins de curso da direção, sensores dos postos de trabalho e avisadores de emergência. Todo o controlo de movimento e direção bem como a seleção das ações a executar passou a ficar a cargo do software programado no PLC assim como a interação entre o sistema de supervisão instalado num posto de controlo e o PLC através de comunicação via rádio. O uso do PLC permitiu a flexibilidade de mudar facilmente a forma como as saídas digitais são usadas, ao contrário de um circuito eletrónico que necessita de uma completa remodelação, tempo de testes e implementação para efetuar a mesma função. O uso de um microcontrolador seria igualmente viável para a aplicação em causa, no entanto o uso do PLC tem a vantagem de ser robusto, mais rápido na velocidade de processamento, existência de software de interface de programação bastante intuitivo e de livre acesso, facilidade de alterar a programação localmente ou remotamente, via rádio, acesso a vários protocolos de comunicação robustos como Modbus, Canbus, Profinet, Modnet, etc., e acesso integrado de uma consola gráfica totalmente programável. iv É ainda possível a sua expansão com adição de módulos de entradas e saídas digitais e/ou analógicas permitindo expandir largamente o uso do AGV para outros fins. A solução está a ser amplamente testada e validada no Laboratório de Automação (LabA) do Departamento de Engenharia Mecânica do ISEP (Instituto Superior de Engenharia do Porto), permitindo a otimização dos sistemas de controlo de direção bem como a interatividade entre o PLC e o programa de interface/supervisão do posto de trabalho.

Reaktorisydämen valvontajärjestelmän modernisointi Olkiluodon kiehutusvesilaitoksella

Reaktorisydämen valvonnalla varmistetaan, että polttoaineelta vaaditut termiset marginaalit toteutuvat ja polttoaineen suojakuori säilyy ehjänä. Olkiluodon kiehutusvesilaitoksen nykyinen sydämen valvontajärjestelmä koostuu SIMULATE-3-sydänsimulaattoriohjelmasta, reaktorisydämen instrumentoinnista, termisen tehon laskentaohjelmasta, tiedonkeruuohjelmista ja käynnistysautomatiikasta. Uusi järjestelmä koostuu näiden lisäksi GARDEL-ohjelmasta, joka on kehitetty kevytvesireaktoreiden sydämen käytön suunnitteluun ja valvontaan. GARDEL käyttää laskentaan samoja ohjelmia, jotka ovat jo Olkiluodon kiehutusvesilaitoksella käytössä. Tämän työn tarkoituksena oli verrata nykyistä ja uutta sydämen valvontajärjestelmää Olkiluodon kiehutusvesilaitoksella. Työssä tutkittiin LPRM-detektorien kalibroinnin jälkeisen datan käsittelyä, palamapäivitystä, stabiilisuuslaskentaa ja adaptiivisia menetelmiä. Järjestelmien vertailuun käytettiin Olkiluoto 2 -laitosyksiköltä käyttöjaksolta 31 (2011–2012) saatuja laskentuloksia. Tulosten perusteella havaittiin uuden järjestelmän laskennassa yksittäisiä virheitä, jotka tulee korjata. Lisäksi uuden järjestelmän toiminnasta tarvitaan lisäselvitystä.

Bank restructuring and financial institution reform in Indonesia

The banking sector underwent drastic reform in post-crisis Indonesia. Bank restructuring, driven by IMF conditionalities, resulted in the exit of insolvent banks and ownership changes of major private banks. Through recapitalization and sales of government-held shares, foreign-owned banks emerged as leading actors in the place of business-group-affiliated banks. As part of the restructuring process, an exit rule was created. The central bank, which up to that time had been given only partial authority under the jurisdiction of the Minister of Finance, now gained a full range of authority over banks. The central bank's supervision system on banks, risk management systems at individual banks, and their efforts to build risk management capacities, began to function. This is totally different from the old financial institution under the Soeharto regime, where banks had no incentive to control risks, as the regime tacitly ensured their survival.

Formação e supervisão das práticas clínicas : uma abordagem ecológica

Nos últimos anos, um conjunto de mudanças de natureza tecnológica institucional, legal e cultural alteraram as funções, a responsabilidade social e a estrutura das organizações de saúde. Estas transformações estão na base do debate actual sobre supervisão clínica em enfermagem enquanto estratégia de promoção da satisfação profissional, segurança e qualidade dos cuidados. A emergência da supervisão clínica em enfermagem permitiu interrogar e dar visibilidade a novas modalidades de formação no contexto de trabalho. A supervisão clínica é um processo multidimensional que inclui encontros regulares entre supervisores e supervisados, com o objectivo de analisar experiências de trabalho e de formação. Dedica-se especial atenção às dimensões emocionais, qualidade de cuidados, relação terapêutica e desenvolvimento pessoal e profissional. A presente pesquisa assume a forma de um estudo de caso realizado num hospital psiquiátrico (Hospital Magalhães Lemos). O objectivo principal do estudo consistiu em compreender o processo amplo e complexo de aprendizagens desenvolvidas em contexto clínico e a forma como estas condicionam as estratégias supervisivas. Recorrendo ao modelo bioecológico de Bronfenbrenner, o estudo interroga de forma sistemática a origem e as relações entre formação e supervisão. Os participantes do estudo foram 18 enfermeiros do referido hospital. Contamos, igualmente, com a colaboração de três peritos com profundo conhecimento da cultura e realidade hospitalar. A informação foi colhida com base em questionários e entrevistas semiestruturadas. O questionário (Clinical Supervision Nursing Inventory – CSNI - V1) inclui três partes. A parte I e II foram relevantes para caracterizar os participantes e o contexto clínico. A parte III do instrumento inclui um inventário com 24 itens. O Alfa de Cronbach calculado pelo autor foi de 0,93 para os 24 itens da escala, indicando excelentes resultados psicométricos. A entrevista semi-estruturada foi usada para a recolha de dados junto dos três peritos. Os enfermeiros possuem uma atitude positiva perante a supervisão clínica. O desenvolvimento pessoal e profissional dos enfermeiros estava relacionado com as oportunidades de formação emergentes no contexto das práticas. Embora a expressão “supervisão clínica” seja por vezes utilizada de forma incorrecta nas organizações, concluímos que existiam no hospital boas práticas a nível da supervisão dos cuidados, relacionando desenvolvimento pessoal, qualidade de cuidados e competências profissionais. Tentámos problematizar as experiências supervisivas partindo de teorias sócio-culturais e bio-ecológicas. Os participantes do estudo referiram que há necessidade de formalizar o sistema de supervisão clínica em enfermagem, evitando relacionálo com o sistema de supervisão de gestão. São apresentados e discutidos diversos subsídios para o desenvolvimento do sistema de supervisão clínica em enfermagem, no hospital.

Supervision as control system : the design of supervision as a regulatory instrument in the social services sector in Sweden

In this article, the prevailing official view of supervision as a regulatory instrument is examined as it applies to the social services sector in Sweden. The study is based on a comparison of the views expressed on the design of supervision as a regulatory instrument by two government commissions, the Supervision Commission and the Commission on Supervision within the Social Services (UTIS), and on the positions taken by the Government regarding the definitions of the concept of supervision proposed by these commissions. The view of supervision as a regulatory instrument expressed in these policy documents is analysed with the help of a theoretical framework describing the components, their functions and the governance characteristics of control systems. In the framework separate interrelated characteristics of the components are identified and summarized into two models of control systems. The analysis shows that supervision in the Swedish social services sector can be described in terms of both a disciplinary and non-disciplinary system. By its system theoretical basis and the identification of interrelated characteristics the study contributes to a broadened understanding of the construction and functions of supervision as a regulatory instrument and of how supervision within the Swedish social sector is meant to be designed.

Business under supervision – pathologies serving the system of power in Russia. OSW COMMENTARY NUMBER 212 | 31.05.2016

The relations between Russia’s authorities and business circles are subordinated not so much to rational economic calculations as to the interests of political elites. The key interest in this case is maintaining the current model of government. The formal and informal supervision of business by law enforcement agencies is an important element of Russia’s economic reality. Despite the rhetoric of high-ranking officials, intended to suggest that the state is taking care of businesspeople’s interests, it is evident that there is no will to devise a systemic solution to the most urgent problems, including the state institutions’ disrespect for the rights of ownership.
