An approximation method using approximate approximations

The aim of this paper is to extend the method of approximate approximations to boundary value problems. This method was introduced by V. Maz'ya in 1991 and has been used until now for the approximation of smooth functions defined on the whole space and for the approximation of volume potentials. In the present paper we develop an approximation procedure for the solution of the interior Dirichlet problem for the Laplace equation in two dimensions using approximate approximations. The procedure is based on potential theoretical considerations in connection with a boundary integral equations method and consists of three approximation steps as follows. In a first step the unknown source density in the potential representation of the solution is replaced by approximate approximations. In a second step the decay behavior of the generating functions is used to gain a suitable approximation for the potential kernel, and in a third step Nyström's method leads to a linear algebraic system for the approximate source density. For every step a convergence analysis is established and corresponding error estimates are given.

Enzymkinetik in der Schule

Urease ist ein Enzym, das Harnstoff spaltet und dessen Reaktionsgeschwindigkeit leicht mittels Leitfähigkeitsmessungen bestimmt werden kann. Dieses Experiment kann, als Schüler- oder Demonstrationsversuch, im Biologie- und Chemieunterricht der Oberstufe von qualitativen Betrachtungen bis hin zur Ermittlung komplexer kinetischer Beschreibungen (Michaelis-Menten-Kinetik) ausgewertet werden.

Safe Distributed Coordination of Heterogeneous Robots through Dynamic Simple Temporal Networks

Research on autonomous intelligent systems has focused on how robots can robustly carry out missions in uncertain and harsh environments with very little or no human intervention. Robotic execution languages such as RAPs, ESL, and TDL improve robustness by managing functionally redundant procedures for achieving goals. The model-based programming approach extends this by guaranteeing correctness of execution through pre-planning of non-deterministic timed threads of activities. Executing model-based programs effectively on distributed autonomous platforms requires distributing this pre-planning process. This thesis presents a distributed planner for modelbased programs whose planning and execution is distributed among agents with widely varying levels of processor power and memory resources. We make two key contributions. First, we reformulate a model-based program, which describes cooperative activities, into a hierarchical dynamic simple temporal network. This enables efficient distributed coordination of robots and supports deployment on heterogeneous robots. Second, we introduce a distributed temporal planner, called DTP, which solves hierarchical dynamic simple temporal networks with the assistance of the distributed Bellman-Ford shortest path algorithm. The implementation of DTP has been demonstrated successfully on a wide range of randomly generated examples and on a pursuer-evader challenge problem in simulation.

Bacteriemia asociada a catéter epicutáneo en la unidad de cuidado intensivo neonatal de la Fundación Cardioinfantil

La bacteriemia asociada a catéter afecta a pacientes en las unidades de cuidado intensivo con una alta morbilidad, mortalidad y aumento de los costos al sistema de salud. Los recién nacidos son la población de más alto riesgo por el mayor uso de catéteres centrales. Objetivo: Caracterizar factores de riesgo para bacteriemia asociada a catéter en la Unidad de Cuidado Intensivo Neonatal de la Fundación Cardioinfantil entre 2005 - 2010 Materiales y método: Estudio descriptivo de corte transversal, incluyó todos los recién nacidos con diagnostico de bacteriemia asociada a catéter. Se analizó la información utilizando frecuencias y medidas de tendencia central. Resultados: Se encontraron 50 pacientes con diagnostico de bacteriemia asociada a catéter. 50% de género masculino, 52% con edad gestacional al nacimiento menor a 36 semanas y 24% con peso menor a 1500 gramos al momento de la inserción del catéter. La edad fue de 24.2 días al momento de la inserción del catéter. En el 66% de los pacientes el sitio de inserción fue el miembro superior, siendo el Sthaphylococcus Epidermidis el germen con el 50% de las bacteriemias. Conclusión: La bacteriemia asociada a catéter afecta paciente prematuros, de bajo peso sin diferencias en genero. La manipulación de dichos dispositivos, el sitio de inserción, el uso previo de antibióticos, la duración del catéter y el uso de nutrición parenteral son factores que están asociados al mayor riesgo de infección. Siendo el Staphylococcus Epidermidis el germen mas frecuente.

A motivação empreendedora e a satisfação com o desempenho organizacional em empresas de pequeno e médio porte de Blumenau: uma análise da indústria local

The current study arose from previous studies made by McClelland (1972), Namam; Slevin (1993), Kuratko; Hornsby; Naffziger (1997), Hoeltgebaum; Kato (2002); Hoeltgebaum;Debastini (2003), Hoeltgebaum; Santos; Loesch (2003) and Hoeltgebaum; Santos (2003). Its objective is to understand the reasons that that lead an entrepreneur to open his ownbusiness, his degree of satisfaction and to perceive if there is a relation between entrepreneurial motivation and the performance of companies. In order to concretize the objective, a descriptive qualitative/quantitative research was realized, amounting to 88 questions of a closed type, statistically ordered. Data collection was achieved by means of a questionnaire divided into 4 parts. Once responses to the questionnaires were obtained, analysis was performed on them, using LHSTAT software. Among the principal results, it was evident in the analysis of the questionnaires that there were a variety of motivations for opening a new business present among the interviewed, with a small, distinct difference in the frequency of the responses. When the satisfaction of the respondents regarding the performance of the company was analyzed, it was perceived that the greatest satisfaction derived from gross and net profit margin and return on investment. Several interdependencies between motivation and satisfactionand performance were evident in the research, with three in particular being the strongest. It was decided to include a category regarding behavioral characteristics of entrepreneurs tothe objectives of the project in which, according to the interviewees, these have a strong entrepreneurial profile; results showed that all the characteristics are well developed. It wasconcluded that the intrinsic motivations are more evident in the entrepreneurs interviewed and that the greatest satisfaction among them lies in the area of gross and net profit margin andin return over investment. It was perceived that there are clear relationships between the motivation of entrepreneurs and satisfaction with the performance of companies.

Asymmetries in Business Cycles

Esta disertación busca estudiar los mecanismos de transmisión que vinculan el comportamiento de agentes y firmas con las asimetrías presentes en los ciclos económicos. Para lograr esto, se construyeron tres modelos DSGE. El en primer capítulo, el supuesto de función cuadrática simétrica de ajuste de la inversión fue removido, y el modelo canónico RBC fue reformulado suponiendo que des-invertir es más costoso que invertir una unidad de capital físico. En el segundo capítulo, la contribución más importante de esta disertación es presentada: la construcción de una función de utilidad general que anida aversión a la pérdida, aversión al riesgo y formación de hábitos, por medio de una función de transición suave. La razón para hacerlo así es el hecho de que los individuos son aversos a la pérdidad en recesiones, y son aversos al riesgo en auges. En el tercer capítulo, las asimetrías en los ciclos económicos son analizadas junto con ajuste asimétrico en precios y salarios en un contexto neokeynesiano, con el fin de encontrar una explicación teórica de la bien documentada asimetría presente en la Curva de Phillips.
