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).

Power efficiency is one of the most important constraints in the design of embedded systems since such systems are generally driven by batteries with limited energy budget or restricted power supply. In every embedded system, there are one or more processor cores to run the software and interact with the other hardware components of the system. The power consumption of the processor core(s) has an important impact on the total power dissipated in the system. Hence, the processor power optimization is crucial in satisfying the power consumption constraints, and developing low-power embedded systems. A key aspect of research in processor power optimization and management is “power estimation”. Having a fast and accurate method for processor power estimation at design time helps the designer to explore a large space of design possibilities, to make the optimal choices for developing a power efficient processor. Likewise, understanding the processor power dissipation behaviour of a specific software/application is the key for choosing appropriate algorithms in order to write power efficient software. Simulation-based methods for measuring the processor power achieve very high accuracy, but are available only late in the design process, and are often quite slow. Therefore, the need has arisen for faster, higher-level power prediction methods that allow the system designer to explore many alternatives for developing powerefficient hardware and software. The aim of this thesis is to present fast and high-level power models for the prediction of processor power consumption. Power predictability in this work is achieved in two ways: first, using a design method to develop power predictable circuits; second, analysing the power of the functions in the code which repeat during execution, then building the power model based on average number of repetitions. In the first case, a design method called Asynchronous Charge Sharing Logic (ACSL) is used to implement the Arithmetic Logic Unit (ALU) for the 8051 microcontroller. The ACSL circuits are power predictable due to the independency of their power consumption to the input data. Based on this property, a fast prediction method is presented to estimate the power of ALU by analysing the software program, and extracting the number of ALU-related instructions. This method achieves less than 1% error in power estimation and more than 100 times speedup in comparison to conventional simulation-based methods. In the second case, an average-case processor energy model is developed for the Insertion sort algorithm based on the number of comparisons that take place in the execution of the algorithm. The average number of comparisons is calculated using a high level methodology called MOdular Quantitative Analysis (MOQA). The parameters of the energy model are measured for the LEON3 processor core, but the model is general and can be used for any processor. The model has been validated through the power measurement experiments, and offers high accuracy and orders of magnitude speedup over the simulation-based method.

Objetivo: Estimar la relación entre indicadores de desempeño muscular y estado nutricional con la velocidad/agilidad, en una muestra de escolares de instituciones educativas del Distrito de Bogotá, Colombia, perteneciente al estudio FUPRECOL. Materiales y Métodos: estudio transversal, en 2803 niños y 3952 niñas (58.5 %), entre 9 y 17 años de edad, pertenecientes a 24 instituciones educativas del sector oficial, en Bogotá, Colombia. La velocidad/agilidad se evaluó con la prueba de carrera de ida y vuelta 4x10 m y los indicadores de fuerza muscular fueron medidos por medio de fuerza prensil, salto longitudinal. Las asociaciones se estimaron por medio de regresión logística binaria. Resultados: el 74.6 % de las mujeres y el 68.6 % de los varones mostraron bajos niveles de velocidad/agilidad; en mujeres, el modelo de regresión logística binario se observa que aquellas que tener bajos niveles de velocidad/agilidad se asociaba con obesidad (OR 2.25 IC 95 % 1.53-3.11), sobrepeso (OR 1.43 IC 95 % 1.19-1.72), bajos niveles de salto longitudinal (OR 2.06 IC 95 % 1.73-2.44) y tener valores de fuerza prensi no saludable (OR 1.45 IC 95 % 1.25-1.88). En hombres, tener entre 9-12 años, (OR 1.89 IC 95% 1.53-2.53), padecer de sobrepeso (OR 2.11 IC 95% 1.63-2.74) u obesidad (OR 3.00 IC 95% 2.03-4.43), se asoció con bajos niveles de velocidad/agilidad. Conclusión: se encontró que un alto porcentaje de la muestra estudiada tiene bajos niveles de velocidad/agilidad; adicionalmente, se observó una fuerte relación entre los indicadores de adiposidad y desempeño muscular, con los niveles de velocidad/agilidad. Se sugiere la implementación de programas escolares, que contrarresten la aparición de manifestaciones de riesgo cardiometabólico.

O sucesso de uma gestão baseada na estratégia reside, no aproveitamento racional e eficiente dos seus recursos humanos, financeiros e organizacionais, bem como na sua capacidade para concretizar objectivos e alcançar resultados. Esta dissertação foi elaborada baseando-se no pressuposto que, a selecção e a aplicação de um Instrumento de Apoio à Gestão em unidades privadas de fisioterapia (UPF’s) permitirão induzir níveis acrescidos de melhoria do desempenho individual e/ou organizacional. Constituiu objectivo geral da mesma contribuir para a sensibilização e a difusão alargada das ferramentas de apoio à gestão que, aplicadas naquelas unidades, poderiam induzir níveis acrescidos de melhoria do desempenho. Definiram-se ainda três objectivos específicos consubstanciando preocupações relacionadas com a reprodução do conhecimento especializado em gestão, com a sua aplicação específica no terreno e com a subjacente criação de valor individual e organizacional. A metodologia utilizada foi a abordagem de Estudo de Caso, inspirada na técnica focus-group, aplicada a três UPF’s, e os resultados obtidos através das análises efectuadas permitiram identificar a ausência da aplicação de instrumentos de apoio à gestão e de avaliação de desempenho, bem como níveis elevados de desempenho, satisfação e autonomia nos profissionais de fisioterapia, constituindo estes a base para justificar a necessidade urgente da elaboração de um plano de implementação de um sistema de avaliação de desempenho nas unidades estudadas. /ABSTRACT: The success of a management based on strategy relies in the rational and efficient use of its human, financial and organizational resources, as well as its ability to achieve objectives and results. This thesis was developed, based on the assumption that the selection and application of a management support instrument in private physiotherapy units would induce higher levels of individual performance and / or organization. It was general objective the contribution to the sensibilization and diffusion of tools to support management, which applied in those units, could induce higher levels of performance. There were defined three specific objectives which concerned whereabouts with the reproduction of specialized knowledge in management, with its specified applicability in the work field and with the underneath creation of individual and organizational value. The applied methodology was a case study, inspired by the focus-group technique applied in three private physiotherapy units, and the results obtained through the analysis allowed the identification of lack of use of any support management tools and performance evaluation, as well as high standard levels of performance, satisfaction and professional autonomy in physical therapists, being this the base for justifying the urgent need for developing an implementation plan of a performance evaluation system applied to these units.

Optimal allocation of water resources for various stakeholders often involves considerable complexity with several conflicting goals, which often leads to multi-objective optimization. In aid of effective decision-making to the water managers, apart from developing effective multi-objective mathematical models, there is a greater necessity of providing efficient Pareto optimal solutions to the real world problems. This study proposes a swarm-intelligence-based multi-objective technique, namely the elitist-mutated multi-objective particle swarm optimization technique (EM-MOPSO), for arriving at efficient Pareto optimal solutions to the multi-objective water resource management problems. The EM-MOPSO technique is applied to a case study of the multi-objective reservoir operation problem. The model performance is evaluated by comparing with results of a non-dominated sorting genetic algorithm (NSGA-II) model, and it is found that the EM-MOPSO method results in better performance. The developed method can be used as an effective aid for multi-objective decision-making in integrated water resource management.

Reduced economic circumstances havemoved management goals towards higher profit, rather than maximum sustainable yields in several Australian fisheries. The eastern king prawn is one such fishery, for which we have developed new methodology for stock dynamics, calculation of model-based and data-based reference points and management strategy evaluation. The fishery is notable for the northward movement of prawns in eastern Australian waters, from the State jurisdiction of New South Wales to that of Queensland, as they grow to spawning size, so that vessels fishing in the northern deeper waters harvest more large prawns. Bioeconomic fishing data were standardized for calibrating a length-structured spatial operating model. Model simulations identified that reduced boat numbers and fishing effort could improve profitability while retaining viable fishing in each jurisdiction. Simulations also identified catch rate levels that were effective for monitoring in simple within-year effort-control rules. However, favourable performance of catch rate indicators was achieved only when a meaningful upper limit was placed on total allowed fishing effort. Themethods and findings will allow improved measures for monitoring fisheries and inform decision makers on the uncertainty and assumptions affecting economic indicators.

Objective Describe the methodology and selection of quality indicators (QI) to be implemented in the EFFECT (EFFectiveness of Endometrial Cancer Treatment) project. EFFECT aims to monitor the variability in Quality of Care (QoC) of uterine cancer in Belgium, to compare the effectiveness of different treatment strategies to improve the QoC and to check the internal validity of the QI to validate the impact of process indicators on outcome. Methods A QI list was retrieved from literature, recent guidelines and QI databases. The Belgian Healthcare Knowledge Center methodology was used for the selection process and involved an expert's panel rating the QI on 4 criteria. The resulting scores and further discussion resulted in a final QI list. An online EFFECT module was developed by the Belgian Cancer Registry including the list of variables required for measuring the QI. Three test phases were performed to evaluate the relevance, feasibility and understanding of the variables and to test the compatibility of the dataset. Results 138 QI were considered for further discussion and 82 QI were eligible for rating. Based on the rating scores and consensus among the expert's panel, 41 QI were considered measurable and relevant. Testing of the data collection enabled optimization of the content and the user-friendliness of the dataset and online module. Conclusions This first Belgian initiative for monitoring the QoC of uterine cancer indicates that the previously used QI selection methodology is reproducible for uterine cancer. The QI list could be applied by other research groups for comparison. © 2013 Elsevier Inc.
