Caracterização geomorfológica das áreas associadas a zonas de falhas na bacia de Taubaté SP

Landscape is the result of interaction between tectonic, weathering and pedogenetic processes, so it is necessary to understand the morphogenesis and relate it to the landforms and landscape. Therefore, this project comprises a geomorphological characterization of some areas associated with the fault zones of Taubaté Basin, at the surroundings of the cities from São José dos Campos to Taubaté SP, emphasizing the Quaternary landscape evolution, where the normal faults played an important role in controling and they were originated, mostly, from the reactivation of Precambrian fault zones by tectonic action. The rift valley scenario is highlighted in the region, identifying the sharp relief from the basin boundary, featuring both Serra do Mar and Serra da Mantiqueira, and a central depressed area where the Taubaté Basin is located. Deforming or modifying basin features are identified, promoting the rearrangement and conditioning of the drainage network and relief, which indicates the presence of morphostructures, conducting to the deduction of a late tectonic process

Metodologia de determinação de funções de pertinência de controla-dores fuzzy para a avaliação energética de empresas de avicultura de postura

The objective of this work is to determine the membership functions for the construction of a fuzzy controller to evaluate the energy situation of the company with respect to load and power factors. The energy assessment of a company is performed by technicians and experts based on the indices of load and power factors, and analysis of the machines used in production processes. This assessment is conducted periodically to detect whether the procedures performed by employees in relation to how of use electricity energy are correct. With a fuzzy controller, this performed can be done by machines. The construction of a fuzzy controller is initially characterized by the definition of input and output variables, and their associated membership functions. We also need to define a method of inference and a processor output. Finally, you need the help of technicians and experts to build a rule base, consisting of answers that provide these professionals in function of characteristics of the input variables. The controller proposed in this paper has as input variables load and power factors, and output the company situation. Their membership functions representing fuzzy sets called by linguistic qualities, as “VERY BAD” and “GOOD”. With the method of inference Mandani and the processor to exit from the Center of Area chosen, the structure of a fuzzy controller is established, simply by the choice by technicians and experts of the field energy to determine a set of rules appropriate for the chosen company. Thus, the interpretation of load and power factors by software comes to meeting the need of creating a single index that indicates an overall basis (rational and efficient) as the energy is being used.

Gestión de pacientes de un Servicio de Urgencias Hospitalarias

[ES] Un servicio de urgencias de una zona ofrece asistencia sanitaria y tiene como principal objetivo atender la patología urgente que acude al hospital y el nivel de compromiso que se asume consiste en diagnosticar, tratar y estabilizar, en la medida posible, dicha patología urgente. Otro objetivo es gestionar la demanda de atención urgente por parte del ciudadano a través de un sistema de selección prioritaria inicial (Triaje) que selecciona, prioriza, organiza y gestiona la demanda de atención. Para poder controlar y realizar el trabajo de la forma más eficaz se utilizan herramientas de gestión necesarias para el control de los pacientes, desde que se realiza su ingreso en el servicio de urgencias hasta el alta del mismo. Las aplicaciones desarrolladas son las siguientes: Gestión de Pacientes en Urgencias: Esta aplicación asignará un estado inicial al paciente y permitirá ir cambiando el estado del mismo usando el método del Triaje (valoración), el más difundido en la medicina de urgencias. Además, se podrán solicitar pruebas diagnósticas y la visualización de marcadores de analíticas para comprobar su evolución. Finalmente, se podrá desarrollar un informe de alta para el paciente. Informadores de Urgencias: La aplicación gestiona la localización física del paciente dentro del servicio de urgencias, permitiendo asimismo el cambio entre las distintas localizaciones y el control para la información a los familiares de los mismos, pudiendo almacenar los familiares y teléfonos de contactos para que estos puedan ser informados. El desarrollo se ha realizado utilizando el MVC (modelo - vista - controlador) que es patrón de arquitectura que separa los datos de una aplicación, la interfaz gráfica de usuario y la lógica de control de componentes. El software utilizado para el desarrollo de las aplicaciones es CACHÉ de Intersystems que permite la creación de una base de datos multidimensional. El modelo de objetos de Caché se basa en el estándar ODMG (Object Database Management Group, Grupo de gestión de bases de datos de objetos) y soporta muchas características avanzadas. CACHÉ dispone de Zen, una biblioteca completa de componentes de objetos preconstruidos y herramientas de desarrollo basadas en la tecnología CSP (Caché Server Pages) y de objetos de InterSystems.

Adaptive control of sinusoidal brushless DC motor actuators

Electrical Power Assisted Steering system (EPAS) will likely be used on future automotive power steering systems. The sinusoidal brushless DC (BLDC) motor has been identified as one of the most suitable actuators for the EPAS application. Motor characteristic variations, which can be indicated by variations of the motor parameters such as the coil resistance and the torque constant, directly impart inaccuracies in the control scheme based on the nominal values of parameters and thus the whole system performance suffers. The motor controller must address the time-varying motor characteristics problem and maintain the performance in its long service life. In this dissertation, four adaptive control algorithms for brushless DC (BLDC) motors are explored. The first algorithm engages a simplified inverse dq-coordinate dynamics controller and solves for the parameter errors with the q-axis current (iq) feedback from several past sampling steps. The controller parameter values are updated by slow integration of the parameter errors. Improvement such as dynamic approximation, speed approximation and Gram-Schmidt orthonormalization are discussed for better estimation performance. The second algorithm is proposed to use both the d-axis current (id) and the q-axis current (iq) feedback for parameter estimation since id always accompanies iq. Stochastic conditions for unbiased estimation are shown through Monte Carlo simulations. Study of the first two adaptive algorithms indicates that the parameter estimation performance can be achieved by using more history data. The Extended Kalman Filter (EKF), a representative recursive estimation algorithm, is then investigated for the BLDC motor application. Simulation results validated the superior estimation performance with the EKF. However, the computation complexity and stability may be barriers for practical implementation of the EKF. The fourth algorithm is a model reference adaptive control (MRAC) that utilizes the desired motor characteristics as a reference model. Its stability is guaranteed by Lyapunov’s direct method. Simulation shows superior performance in terms of the convergence speed and current tracking. These algorithms are compared in closed loop simulation with an EPAS model and a motor speed control application. The MRAC is identified as the most promising candidate controller because of its combination of superior performance and low computational complexity. A BLDC motor controller developed with the dq-coordinate model cannot be implemented without several supplemental functions such as the coordinate transformation and a DC-to-AC current encoding scheme. A quasi-physical BLDC motor model is developed to study the practical implementation issues of the dq-coordinate control strategy, such as the initialization and rotor angle transducer resolution. This model can also be beneficial during first stage development in automotive BLDC motor applications.
