A apicultura, definida atualmente como a cria??o racional de abelhas, ? uma importante atividade econ?mica mundial que movimenta anualmente um mercado milion?rio. O desenvolvimento eficiente da atividade ap?cola envolve in?meros desafios de diversas ?reas de atua??o e conhecimento, que vai desde opera??es cotidianas de manuten??o do api?rio at? o monitoramento comportamental das abelhas e do ambiente no qual o api?rio esta inserido. A UEPA-EAJ (Unidade de Extra??o de Produtos Ap?colas, da Escola Agr?cola de Jundia?) ? um centro de atividades, estudos e pesquisas ap?colas do RN. Esse trabalho prop?s ent?o o desenvolvimento de uma ferramenta com recursos computacionais de automa??o e controle com os objetivos de auxiliar e dar um maior embasamento aos estudos e pesquisas realizadas pela UEPA-EAJ, bem como o de facilitar atividades cotidianas presentes no manejo do api?rio dessa unidade. A ferramenta concebida, denominada Beehiveior, foi dividida em dois m?dulos independentes: uma central de automa??o e controle, respons?vel pela coleta e envio de dados das colmeias, e um aplicativo Web, com a fun??o de processar, armazenar e exibir os dados coletados. Foi utilizado hardware de baixo custo, reciclado e/ou de f?cil obten??o para constru??o da central. O projeto possui como resultados o aplicativo Web, os c?digos-fontes e esquemas de automa??o, o relato dos experimentos realizados e um comparativo do Beehiveior com os trabalhos relacionados. Atualmente a ferramenta ? capaz de monitorar vari?veis da colmeia (ex.: temperatura e umidade), enviar os dados coletados via rede cabeada Ethernet ou atrav?s da transfer?ncia dos dados armazenados localmente em cart?o de mem?ria e exibir esses valores, na forma de gr?ficos e tabela, no aplicativo Web. / Bees are very important animals to the global ecosystem, mainly for their active role in pollination process of many plants on the planet. Beekeeping, currently defined as the rational creation of bees, is a global economic activity that annually moves a millionaire market. The efficient development of beekeeping involves numerous challenges in many aspects, ranging from daily activities to keep the apiary until monitor the behavior of bees and the apiary environment. The UEPA-EAJ (an unit for explore bee products at Jundia??s agricultural school) is a center for activities, studies and research on beekeeping in Brazil-RN. This work proposes the development of tool with computational resources and composed by automation and control devices, with the goal to give a better basis for the studies and researches carried out by UEPA-EAJ, as well to improve the daily activities to maintain the apiary of this unit. The developed tool, called beehiveior, was split in two modules that works independents: one piece for automation and control, which collects and sends hive's data, and a web application that processes, stores and displays the collected data. Low cost hardware, recyclable and/or easily found was used in build process of automation piece. The project leaves as result the web application, automation codes, the report of the experiments and a comparative analysis of the Beehiveior against the related works. Currently the project is able to monitor some data from hive such temperature and humidity, send collected data by an Ethernet wired network or by transfer the data stored locally on a memory card and display these values in the Web application showing them with charts and tables.

Le but de cette thèse est de développer des méthodes pratiques plus performantes pour la détection d'instances de classes d'objets de la vie quotidienne dans les images. Nous présentons une famille de détecteurs qui incorporent trois types d'indices visuelles performantes – histogrammes de gradients orientés (Histograms of Oriented Gradients, HOG), motifs locaux binaires (Local Binary Patterns, LBP) et motifs locaux ternaires (Local Ternary Patterns, LTP) – dans des méthodes de discrimination efficaces de type machine à vecteur de support latent (Latent SVM), sous deux régimes de réduction de dimension – moindres carrées partielles (Partial Least Squares, PLS) et sélection de variables par élagage de poids SVM (SVM Weight Truncation). Sur plusieurs jeux de données importantes, notamment ceux du PASCAL VOC2006 et VOC2007, INRIA Person et ETH Zurich, nous démontrons que nos méthodes améliorent l'état de l'art du domaine. Nos contributions principales sont : – Nous étudions l'indice visuelle LTP pour la détection d'objets. Nous démontrons que sa performance est globalement mieux que celle des indices bien établies HOG et LBP parce qu'elle permet d'encoder à la fois la texture locale de l'objet et sa forme globale, tout en étant résistante aux variations d'éclairage. Grâce à ces atouts, LTP fonctionne aussi bien pour les classes qui sont caractérisées principalement par leurs structures que pour celles qui sont caractérisées par leurs textures. En plus, nous démontrons que les indices HOG, LBP et LTP sont bien complémentaires, de sorte qu'un jeux d'indices étendu qui intègre tous les trois améliore encore la performance. – Les jeux d'indices visuelles performantes étant de dimension assez élevée, nous proposons deux méthodes de réduction de dimension afin d'améliorer leur vitesse et réduire leur utilisation de mémoire. La première, basée sur la projection moindres carrés partielles, diminue significativement le temps de formation des détecteurs linéaires, sans réduction de précision ni perte de vitesse d'exécution. La seconde, fondée sur la sélection de variables par l'élagage des poids du SVM, nous permet de réduire le nombre d'indices actives par un ordre de grandeur avec une réduction minime, voire même une petite augmentation, de la précision du détecteur. Malgré sa simplicité, cette méthode de sélection de variables surpasse toutes les autres approches que nous avons mis à l'essai. – Enfin, nous décrivons notre travail en cours sur une nouvelle variété d'indice visuelle – les « motifs locaux quantifiées » (Local Quantized Patterns, LQP). LQP généralise les indices existantes LBP / LTP en introduisant une étape de quantification vectorielle – ce qui permet une souplesse et une puissance analogue aux celles des approches de reconnaissance visuelle « sac de mots », qui sont basées sur la quantification des régions locales d'image considérablement plus grandes – sans perdre la simplicité et la rapidité qui caractérisent les approches motifs locales actuelles parce que les résultats de la quantification puissent être pré-compilés et stockés dans un tableau. LQP permet une augmentation considérable de la taille du support local de l'indice, et donc de sa puissance discriminatoire. Nos expériences indiquent qu'elle a la meilleure performance de toutes les indices visuelles testés, y compris HOG, LBP et LTP. / The goal of this thesis is to develop better practical methods for detecting common object classes in real world images. We present a family of object detectors that combine Histogram of Oriented Gradient (HOG), Local Binary Pattern (LBP) and Local Ternary Pattern (LTP) features with efficient Latent SVM classifiers and effective dimensionality reduction and sparsification schemes to give state-of-the-art performance on several important datasets including PASCAL VOC2006 and VOC2007, INRIA Person and ETHZ. The three main contributions are as follows. Firstly, we pioneer the use of Local Ternary Pattern features for object detection, showing that LTP gives better overall performance than HOG and LBP, because it captures both rich local texture and object shape information while being resistant to variations in lighting conditions. It thus works well both for classes that are recognized mainly by their structure and ones that are recognized mainly by their textures. We also show that HOG, LBP and LTP complement one another, so that an extended feature set that incorporates all three of them gives further improvements in performance. Secondly, in order to tackle the speed and memory usage problems associated with high-dimensional modern feature sets, we propose two effective dimensionality reduction techniques. The first, feature projection using Partial Least Squares, allows detectors to be trained more rapidly with negligible loss of accuracy and no loss of run time speed for linear detectors. The second, feature selection using SVM weight truncation, allows active feature sets to be reduced in size by almost an order of magnitude with little or no loss, and often a small gain, in detector accuracy. Despite its simplicity, this feature selection scheme outperforms all of the other sparsity enforcing methods that we have tested. Lastly, we describe work in progress on Local Quantized Patterns (LQP), a generalized form of local pattern features that uses lookup table based vector quantization to provide local pattern style pixel neighbourhood codings that have the speed of LBP/LTP and some of the flexibility and power of traditional visual word representations. Our experiments show that LQP outperforms all of the other feature sets tested including HOG, LBP and LTP.

It consists of a micro-indenter which is driven by a gear system driven by three-rectified. The sample to be tested is placed on a table that contains a load cell that measures the deformation in the sample during the penetration of micro-indenter. With this prototype it is possible to measure the elastic deformation of the material obtained by calculating the depth of penetration in the sample from the difference of turns between the start of load application to the application of the load test and return the indenter until the complete termination of load application. To determine the hardness was used to measure the depth of plastic deformation. We used 7 types of steel trade to test the apparatus. There was a dispersion of less than 10% for five measurements made on each sample and a good agreement with the values of firmness provided by the manufacturers. / Nesse trabalho ? desenvolvido um prot?tipo para an?lise din?mica e quantitativa da dureza de superf?cies met?licas atrav?s de ensaios de penetra??o.

However, alarms and events are often confused and improperly configured similarly by developers of automation systems. This practice results in a high amount of pseudo-alarms during the operation of industrial processes. The high number of alarms is a major obstacle to improving operational efficiency, making it difficult to identify problems and increasing the time to respond to abnormalities. The main consequences of this scenario are the increased risk to personal safety, facilities, environment deterioration and loss of production. The aim of this paper is to present a philosophy for setting up a system of supervision and control, developed with the aim of reducing the amount of pseudo-alarms and increase reliability of the information that the system provides. A real case study was conducted in the automation system of the offshore production of hydrocarbons from Petrobras in Rio Grande do Norte, in order to validate the application of this new methodology. The work followed the premises of the tool presented in ISA SP18.2. 2009, called "life cycle alarm . After the implementation of methodology there was a significant reduction in the number of alarms / No contexto de opera??o de processos industriais, alarme, por defini??o, ? um aviso ao T?cnico de Opera??o que uma a??o com tempo restrito para ser executada ? necess?ria, enquanto que evento ? uma informa??o de mudan?a de estado e n?o demanda a??o por parte do T?cnico de Opera??o, consequentemente n?o deve ser anunciada, sendo apenas armazenada para fins de an?lise de manuten??o, incidentes e utilizadas para sinaliza??o/monitora??o (EEMUA, 2007). Por?m, alarmes e eventos s?o frequentemente confundidos e configurados inadequadamente de forma semelhante por programadores de sistemas de automa??o. Esta pr?tica resulta em uma elevada quantidade de pseudo-alarmes durante a opera??o de processos industriais. O elevado n?mero de alarmes configurados ? um dos principais entraves para a melhoria da efici?ncia operacional, dificultando a identifica??o de problemas e aumentando o tempo de resposta ?s anormalidades. As principais conseq??ncias desse quadro s?o o aumento do risco ? seguran?a das pessoas, instala??es, meio ambiente e o agravamento das perdas de produ??o. O objetivo principal deste trabalho ? apresentar uma filosofia de configura??o de um sistema de supervis?o e controle, desenvolvida com o intuito de diminuir a quantidade de pseudo-alarmes configurados e aumentar a confiabilidade das informa??es que o sistema fornece. Um estudo de caso foi realizado no sistema de automa??o das plataformas mar?timas de produ??o de Hidrocarbonetos da Petrobras no Rio Grande do Norte, de forma a validar a aplica??o dessa nova metodologia. O trabalho seguiu as premissas da ferramenta apresentada na norma ISA SP18.2. 2009, denominado ciclo de vida de alarme .

With this advance, the amount of information that automation systems are subjected to increased significantly. The alarms generated by the monitoring equipment are a major contributor to this increase, and the equipments are usually deployed in industrial plants without a formal methodology, which entails an increase in the number of alarms generated, thus overloading the alarm system and therefore the operators of such plants. In this context, the works of alarm management comes up with the objective of defining a formal methodology for installation of new equipment and detect problems in existing settings. This thesis aims to propose a set of metrics for the evaluation of alarm systems already deployed, so that you can identify the health of this system by analyzing the proposed indices and comparing them with parameters defined in the technical norms of alarm management. In addition, the metrics will track the work of alarm management, verifying if it is improving the quality of the alarm system. To validate the proposed metrics, data from actual process plants of the petrochemical industry were used / A evolu??o da automa??o nos ?ltimos anos tornou poss?vel o monitoramento cont?nuo dos processos de plantas industriais.
