1. Characterization of Otto Chips by Particle Swarm Optimization
Abstract Recently a surface plasmon resonance (SPR) optical sensor, based on the Otto configuration — the Otto chip — has been developed. One essential step in the quality control of the fabrication process is characterization of the active region of several devices in a batch. Characterization is done by measuring the angular spectrum of the optical re

2. Adaptive Filtration of Parameters of the UAV Movement Based on the TDOA-Measurement Sensor Networks
ABSTRACT: In modern conditions unmanned aerial vehicles (UAVs) generate new classes of threats, including their use for terrorist purposes. A feature of modern UAVs is the ability to perform sudden maneuvers and to keep the same position in the point in space. For the description of the UAV movement with various types of maneuver it is used a rectangular coo

3. Classification of Flying Insects with high performance using improved DTW algorithm based on hidden Markov model
ABSTRACT Insects play significant role in the human life. And insects pollinate major food crops consumed in the world. Insect pests consume and destroy major crops in the world. Hence to have control over the disease and pests, researches are going on in the area of entomology using chemical, biological and mechanical approaches. The data relevant to the fl

4. Instrumentação e identificação de um ambiente predial visando controle preditivo do conforto térmico / Instrumentation and building identification aiming predictive control of thermal comfort
The technological basis of Ambient Intelligence is a network of processing units that collect sensor information, process them and act on the environment through actuators, providing the occupants a diversity of services. In this scenario, this manuscript presents a first-principles structured identification approach for a thermal environment consisting of a

5. Monitoração e localização de defeitos na soldagem TIG utilizando técnicas de espectrometria
There is an effort made by industries to improve product quality and production methods, and to decrease the production costs. Welding is one of these processes. There are several studies about controlling or monitoring the welding process. This work presents a on-line non-intrusive monitoring system capable of detecting TIG weld defects. In this way, inspec

6. Airborne geophysical and geological data applied to the selection of groudwater potential areas in crystalline rocks of Ceara, Brazil / Dados aerogeofisicos e geologicos aplicados a seleção de areas favoraveis para agua subterranea no dominio cristalino do Ceara, Brasil
The location of water well in Northeast Brazil is usually based on the interpretation of structural lineaments in aerial-photographs and electromagnetic and electrical resistivity ground geophysics surveys. However, the success of these techniques is variable, and the small coverage area is another limitation. This Thesis favors a different approach, the use

8. IDENTIFICACIÓN DE SISTEMAS DE EXTRUCTURAS MECÁNICAS Y APLICACIONES / IDENTIFICATION OF MECHANICAL SYSTEMS WITH APPLICATIONS / IDENTIFICAÇÃO DE SISTEMAS DE ESTRUTURAS MECÂNICAS E APLICAÇÕES
The aims of this work are three: First, to make a brief review of linear system and estimation theory used in mechanical structure problems. Second, to study an algorithm called ERA (Eigensystem Realization Algorithm) that provides a minimal realization using the input (forces, moments, impulses) and output signals (accelerations). Third, to develop some num

9. LOCALIZAÇÃO ÓTIMA DE SENSORES PARA FILTRAGEM E IDENTIFICAÇÃO EM SISTEMAS DISTRIBUÍDOS / OPTIMAL SENSORS LOCATION FOR FILTERING AND IDENTIFICATION OF DISTRIBUTED SYSTEMS
This thesis deals with the nonlinear problem of simultaneous parameter and state estimation for distributed systems, including the associated optimal sensor location. The class of models under consideration is caracterrized by linear unbounded operators which are densely defined and dissipative. Our approach applies linear filtering techniquess to a sequence

10. Probabilistic secretion of quanta and the synaptosecretosome hypothesis: evoked release at active zones of varicosities, boutons, and endplates.
A quantum of transmitter may be released upon the arrival of a nerve impulse if the influx of calcium ions through a nearby voltage-dependent calcium channel is sufficient to activate the vesicle-associated calcium sensor protein that triggers exocytosis. A synaptic vesicle, together with its calcium sensor protein, is often found complexed with the calcium
