A investigação foi desenvolvida com objetivo de analisar como tem se dado o dimensionamento de pessoal de enfermagem nos hospitais do município de Ribeirão Preto-SP, tendo como sujeitos da pesquisa as coordenadoras de enfermagem de cinco desses hospitais. Para tal, realizamos este estudo exploratório-descritivo, utilizando o método da entrevista, com roteiro de questões fechadas e abertas, sendo realizada análise de conteúdo segundo Bardin (1977). Verificamos que os responsáveis pelo dimensionamento são do sexo feminino, tiveram experiências diversificadas de trabalho na profissão e atualmente ocupam o cargo mais elevado na hierarquia do serviço de enfermagem. A definição acerca do dimensionamento apreendida pelos sujeitos vem ao encontro daquelas encontradas na literatura. Quanto à finalidade do dimensionamento, há a previsão dos profissionais, garantia da operacionalização do trabalho da enfermagem, atendimento à expectativa do cliente com relação às suas necessidades, provimento dos setores de pessoal, garantia da distribuição desses na escala. A utilização do dimensionamento ocorre como justificativa para aumentar o quadro por meio de contratação. Quanto aos parâmetros do dimensionamento, ficaram evidenciados média de permanência, característica da unidade, taxa de ocupação de leitos, modelo de assistência de enfermagem, tipo de clientela, tipo de convênio, composição da equipe de enfermagem e do setor, horas de trabalho por dia e por mês, taxa de absenteísmo, Sistema de Classificação de Pacientes. Em relação às facilidades do dimensionamento, cabe destacar a importância dada ao relacionamento com a diretoria da instituição devido à política de recursos humanos, que ao nosso ver, é fator motivador para essas coordenadoras de enfermagem realizarem a estimativa de pessoal, bem como maior envolvimento das demais enfermeiras, devido à perspectiva relacionada à melhoria da qualidade de assistência atribuída, parcialmente, ao número de pessoal de enfermagem que compõe o quadro de funcionários da instituição. Como desafios foram citados a própria política de recursos humanos, que interfere significativamente em algumas diretrizes do serviço de enfermagem, o baixo poder de decisão da enfermeira com relação a contratação de pessoal tornando a assistência prestada fragilizada e, ainda, há aqueles ligados ao cálculo propriamente dito como compreensão do processo de trabalho de enfermagem, por parte de quem contrata, e a rotatividade. O aspecto legal inerente à profissão também foi abordado. As coordenadoras de enfermagem compreendem que cabe a elas a responsabilidade legal pela estimativa de pessoal. / This research aimed to analyze how nursing staff has been dimensioned at hospitals in Ribeirão Preto-SP, Brazil. Research subjects were nursing coordinators in five of these hospitals. Hence, a qualitative descriptive study was carried out, realizing interviews by means of a script with closed and open questions and content analysis according to Bardin (1977). We observed that the persons responsible for this task are female, with diversified work experience, and currently occupy the highest level in the nursing service hierarchy. The definition of dimensioning as obtained from the subjects corresponds to those found in literature. As to the aim, the following factors stood out: previewing professionals, operational guarantee for nursing work, attending to clients’ expectations in relation to their needs, fill out personnel vacancies, guarantee personnel allocation in the work scale. The usage of the nursing personnel serves as a justification to increase staff through new contracts. As to dimensioning parameters, the following factors stood out: average stay, unit characteristic, bed occupation rate, nursing care model, kind of clientele, kind of agreement, nursing team and sector composition, work hours per day and per month, absenteeism rate, Patient Classification System. With respect to dimensioning facilities, special attention must be granted to the importance the participating nursing coordinators give to the relation with the board of the institution, due to the human resource policy. In our opinion, this factor motivates these nursing coordinators to carry out the personnel estimation, and leads towards greater commitment from other nurses, due to the perspective of improved care quality, which is partially attributed to the number of nursing staff in the institution’s employee cadre. The following challenges were mentioned: the human resource policy itself, which significantly interferes in some nursing service guidelines and nurses’ low level of decision-making power to decide on whether to hire staff or not, which fragilizes the delivered care and, also, the challenges posed by staff dimensioning itself, such as the contracting party’s understanding of the nursing work process and rotation. The legal aspect inherent in the profession was also dealt with. Nursing managers see this estimation as their legal responsibility.

To measure losses in a transformer with today’s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%. But in the end it was discovered that the circuit was only able to deliver 70A when the thought was 200 A. More over was with the frequency of 200 kHz the signal was so distorted that all results over 100 kHz should be questioned. The goal was a efficiency of 99%. That was one of the basis in our calculation and dimensioning. When we order the components we foundbetter than we needed och the efficiency was improved. In the reality the efficiency is 95% and we think it's because the measurements-instruments accuracy and the distortion. In some measurements the efficiency went over 100% and that greatly improve that idea. Every part of the circuit was simulated piece bye piece and then together. That to increase the understanding of the system and to see that themodel works. The simulated efficiency was very low compared to calculated and in reality. The fact was gathered from literature, technical reports from Alstom and meetings with Per Ranstad et. al. / Om man vill mäta förluster på en transformator skerdetta antingen väldigt osäkert eller väldigt långsamt. Det finns en ny metod som Alstomtagit fram, som inte realiserats i ett bestående testsystem förrän nu, vilket har varit detta projekt. Det hela bygger på ett switchat system och en CLR krets i resonansfrekvens. Det resulterade testsystemet hade en beräknad verkningsgrad på 99,8 % och i verkligheten över 95%. Dock i slutskedet upptäcktes att kretsen endast orkade mata ut 70 A jämfört med det tänkta 200 A. Dessutom vid frekvensen 200 kHz blev signalen väldigt förvrängd av störningar och de resultat för frekvenser från 100 kHz och uppåt kan därför ifrågasättas. Vi satte ett mål på en verkningsgrad på 99% som vi grundade våra räkningar och dimensioneringar på. När materialet skulle beställas hittades bättre komponenter än vad vi satt upp och verkningsgraden förbättrades. Varför verklighetens verkningsgrad hamnar på 95% tror vi har med noggrannheten på mätinstrumenten att göra och störningssignalen. Vissa mätningar uppgick till över 100% verkningsgrad som gör att misstankarna för mätinstrumenten stiger. Alla kretsdelar simulerades bit för bit och ihop för att öka förståelsen för systemet samt se att lösningen funkar. Den simulerade verkningsgraden blev väldigt lågt jämfört med beräknat och verkligheten. Fakta vi använt kommer från flera litteraturer, tekniska rapporter från Alstom och möten med Per Ranstad m.fl.

La conception aérodynamique des pales du rotor principal d’un hélicoptère doitsimultanément prendre en compte plusieurs objectifs relatifs aux critères du vol stationnaire etvol d’avancement. Cette thèse vise à développer une boucle d’optimisation automatiséecombinant des algorithmes d’optimisation avancés et des outils de simulation. Deux outils desimulation sont employés pour la prédiction des performances rotor : le code de mécanique devol HOST, ainsi que le code de Mécanique des Fluides Numérique (MFN) elsA. Une analyse deces outils est effectuée pour des cas test bien documentés afin d’estimer leur capacité à prédiredes tendances de performances rotor en fonction de la géométrie de pale. L’influence desparamètres numériques est également caractérisée. Aussi, une stratégie d’optimisation estdéveloppée, permettant la prise en compte de plusieurs objectifs et de contraintes complexes,ainsi que la détermination d’optima globaux pour ce problème multimodale. Suivant cescritères, un algorithme génétique (AG) est sélectionné. Afin de réduire le nombre d’évaluationsnécessaires, une stratégie d’optimisation multi-fidélité est proposée : une optimisationpréliminaire utilisant l’AG et HOST est utilisée pour la réduction de l’espace des paramètres ensélectionnant la zone de haute performance. Ensuite, une surface de réponse est construiteavec des calculs haute-fidélité des pales de haute performance comme vu par l’étapepréliminaire. L’optimisation est finalement effectuée sur cette surface de réponse haute-fidélité.L’approche proposée résulte en une augmentation significative des performances rotor, tout enrespectant le critère industriel relatif au nombre de calculs coûteux comme MFN. L’approcheproposée se révèle être un outil efficace pour la conception de pales du rotor principald’hélicoptère. / The aerodynamic design of helicopter rotor blades requires taking into accountedmultiple objectives simultaneously, to provide a compromise solution for the conflictingrequirements associated to hover and forward flight conditions. The present work aims atdeveloping an automated optimization based on the combination of advanced optimizationalgorithms and simulation tools. As a preliminary step, candidate simulation methods andoptimization algorithms are assessed in detail. Two simulation methods are employed for thecomputation of rotor performance: the in-house Helicopter Overall Simulation Tool (HOST),based on the blade element method, and ONERA’s Computation Fluid Dynamics (CFD) codeelsA. An in-detail analysis of both simulation tools for well documented test cases is carried out,with focus on their capability of predicting trends of the global rotor performance as a function ofblade geometry. The impact of computation settings is also characterized. Then, an optimizationstrategy is developed, allowing the incorporation of multiple objectives and complex constraints,and the detection of global optima for multi-modal problems. Based on these criteria, a geneticalgorithm (GA) is selected. To reduce the number of simulations required to find optimalsolutions, a Multi-Fidelity Optimization (MFO) strategy is proposed: a preliminary low-fidelity GAoptimization stage based on HOST simulations is used to reduce the design space by selectinga high-performance subspace. Then, a CFD-based surrogate model is constructed on thereduced design space by using a sample of high-performance blade from the low-fidelity step.The final optimization step is run on the high-fidelity surrogate. The proposed MFO approachresults in significant rotor performance improvements while using a far lower number of costlyCFD evaluations of the objective functions with respect to a full GA optimization. The proposedapproach is shown to represent an efficient design tool for industrial helicopter rotor blade

Cassandra is a NoSQL(Not only Structured Query Language) database which serves large amount of data with high availability .Cassandra data storage dimensioning also known as Cassandra capacity planning refers to predicting the amount of disk storage required when a particular product is deployed using Cassandra. This is an important phase in any product development lifecycle involving Cassandra data storage system. The capacity planning is based on many factors which are classified as Cassandra specific and Product specific.This study is to identify the different Cassandra specific and product specific factors affecting the disk space in Cassandra data storage system. Based on these factors a model is to be built which would predict the disk storage for Ericsson’s voucher system.A case-study is conducted on Ericsson’s voucher system and its Cassandra cluster. Interviews were conducted on different Cassandra users within Ericsson R&D to know their opinion on capacity planning approaches and factors affecting disk space for Cassandra. Responses from the interviews were transcribed and analyzed using grounded theory.A total of 9 Cassandra specific factors and 3 product specific factors are identified and documented. Using these 12 factors a model was built. This model was used in predicting the disk space required for voucher system’s Cassandra.The factors affecting disk space for deploying Cassandra are now exhaustively identified. This makes the capacity planning process more efficient. Using these factors the Voucher system’s disk space for deployment is predicted successfully.

Als Großdemonstrator des Sonderforschungsbereichs 532 soll auf dem Gelände der Fakultät für Bauingenieurwesen der RWTH Aachen ein Ausstellungspavillon mit einer Dachkonstruktion aus Textilbeton errichtet werden. Der Beitrag zeigt die automatisierte Bemessung dieser komplexen Tragstruktur mit Hilfe eines hierfür entwickelten numerischen Bemessungsstools. Die Auswertung erfolgt für alle Lastfallkombinationen nach DIN 1055-100 und unter Berücksichtigung der Reduktion der Tragfähigkeit der textilen Bewehrung infolge einer Umlenkung im Riss sowie einer Erhöhung der aufnehmbaren Textilspannungen infolge Biegebeanspruchung. Zur Ermittlung der Tragfähigkeit der Textilbetonschale wurden am Institut für Massivbau Dehnkörper- und Biegeversuche durchgeführt, die in Bewehrungsgrad und Dicke dem realen Bauwerk am Schalenrand entsprachen. / Within the collaborate research center 532 at RWTH Aachen University the construction of an exposition hall with a double-curved roof structure consisting of textile reinforced concrete is currently planned. A numerical tool has been developed to calculate the necessary number of reinforcement layers. Further, the tool evaluates the characteristic stresses of the load case combinations in the ultimate limit state taking into account a reduction of the load-bearing capacity of the textile reinforcement due to alignment of the rovings in the crack bridge and a better activation of the inner filaments for bending induced tension. The resistance of the material has been determined in experimental investigations of tensile and bending specimens of the same thickness and reinforcement ratio as the planned shell structure.
