Programa de P?s-Gradua??o em Instrumenta??o, Controle e Automa??o de Processos de Minera??o. Departamento de Engenharia de Controle e Automa??o, Escola de Minas, Universidade Federal de Ouro Preto.Os rolos de transportadores de correias s?o um dos ativos mais cr?ticos da ind?stria da minera??o, cujas falhas trazem grandes impactos para as opera??es. Para evit?-las, s?o realizadas inspe??es regulares de forma sensitiva (sem uso de instrumentos de medi??o), o que diminui a qualidade da inspe??o e ainda exp?e os inspetores a um ambiente com riscos, calor e poeira. As t?cnicas automatizadas para monitoramento de condi??es dos rolos possuem limita??es que dificultam sua ado??o a curto prazo, o que justifica a utiliza??o de uma estrutura de sensoriamento m?vel, aqui chamada Plataforma de Inspe??o, de implementa??o mais r?pida. Assim, o presente trabalho apresenta uma revis?o das principais t?cnicas de monitoramento de condi??es de rolos, prop?e uma arquitetura para suportar a constru??o e evolu??o incremental de Plataformas de Inspe??o e apresenta prot?tipos que validam os conceitos-chave discutidos na arquitetura, particularmente a integra??o da plataforma com sistemas corporativos. O trabalho empregou Ve?culos A?reos N?o Tripulados (VANTs) como base para os prot?tipos e testes em campo, al?m de construir um ambiente virtual de um porto para aplica??es baseadas em VANTs em um simulador.Conveyor belt rollers are one of the most critical assets in the mining industry and their failures bring major impacts to operations. To avoid them, inspectors regularly perform sensitive inspections (without measurement instruments), but they lack quality and expose labor to a hazardous environment, with heat and dust. Automated techniques for rollers? condition monitoring have limitations that hinder their adoption in the short-term. This supports the use of a mobile sensor structure, here called Inspection Platform, which is fast to implement. Therefore, this work presents a revision of the most important condition monitoring techniques for rollers, proposes an architecture to support the construction and incremental evolution of Inspection Platforms and presents prototypes that validate key concepts discussed in the architecture, mainly its integration with enterprise systems. This work employed Unmanned Aerial Vehicles (UAVs) to support the prototypes and field tests. A virtual environment of a port was built to evaluate UAV-based applications in a simulator

Mass Production Processes

It is always hard to set manufacturing systems to produce large quantities of standardized parts. Controlling these mass production lines needs deep knowledge, hard experience, and the required related tools as well. The use of modern methods and techniques to produce a large quantity of products within productive manufacturing processes provides improvements in manufacturing costs and product quality. In order to serve these purposes, this book aims to reflect on the advanced manufacturing systems of different alloys in production with related components and automation technologies. Additionally, it focuses on mass production processes designed according to Industry 4.0 considering different kinds of quality and improvement works in mass production systems for high productive and sustainable manufacturing. This book may be interesting to researchers, industrial employees, or any other partners who work for better quality manufacturing at any stage of the mass production processes

(In)Forming and Pressing Matters: Laying the Foundations for the Preservation and Interpretation of the Western Clay Manufacturing Company

In the United States, brick and tile manufactories were once ubiquitous. Currently, the number of extant late nineteenth- to early-twentieth century complexes devoted to the production of brick and tile products is negligible. Of the few remaining historic manufactories, none evidences what can be found at Helena, Montana’s shuttered Western Clay Manufacturing Company (Western Clay): three generations of kiln technology and numerous intact principal buildings, machinery, and infrastructural elements related to the production of structural and hollow clay tile. Since its closure, Western Clay’s place in historical memory has suffered attrition. Concomitantly, the greater public’s understanding of this manufactory has diminished. Still, this site is poised to tell the little-known but important social, technological, and industrial histories of late nineteenth- and early-twentieth century brickyards. Through in-depth historical research, this thesis will illuminate the significance of Western Clay and begin to reinvest the site with historical memories. In an effort to revitalize, not elide important histories through the removal of buildings, machinery and infrastructural elements that might otherwise fulfill important mnemonic functions and provide both identity constructing and educational functions for both present and future generations, this work also furnishes the manufactory’s stewards and supporters with a site-specific, historically informed rationale for future preservation decision-making. This rationale is grounded in author and preservation professional Ned Kaufman’s concept of “storyscapes.” It is also informed by both the aforementioned body of historical research and a general conditions assessment that was created during the summer of 2011

XVIII International Coal Preparation Congress

Changes in economic and market conditions of mineral raw materials in recent years have greatly increased demands on the ef fi ciency of mining production. This is certainly true of the coal industry. World coal consumption is growing faster than other types of fuel and in the past year it exceeded 7.6 billion tons. Coal extraction and processing technology are continuously evolving, becoming more economical and environmentally friendly. “ Clean coal ” technology is becoming increasingly popular. Coal chemistry, production of new materials and pharmacology are now added to the traditional use areas — power industry and metallurgy. The leading role in the development of new areas of coal use belongs to preparation technology and advanced coal processing. Hi-tech modern technology and the increasing interna- tional demand for its effectiveness and ef fi ciency put completely new goals for the University. Our main task is to develop a new generation of workforce capacity and research in line with global trends in the development of science and technology to address critical industry issues. Today Russia, like the rest of the world faces rapid and profound changes affecting all spheres of life. The de fi ning feature of modern era has been a rapid development of high technology, intellectual capital being its main asset and resource. The dynamics of scienti fi c and technological development requires acti- vation of University research activities. The University must be a generator of ideas to meet the needs of the economy and national development. Due to the high intellectual potential, University expert mission becomes more and more called for and is capable of providing professional assessment and building science-based predictions in various fi elds. Coal industry, as well as the whole fuel and energy sector of the global economy is growing fast. Global multinational energy companies are less likely to be under state in fl uence and will soon become the main mechanism for the rapid spread of technologies based on new knowledge. Mineral resources will have an even greater impact on the stability of the economies of many countries. Current progress in the technology of coal-based gas synthesis is not just a change in the traditional energy markets, but the emergence of new products of direct consumption, obtained from coal, such as synthetic fuels, chemicals and agrochemical products. All this requires a revision of the value of coal in the modern world economy

Neural Extended Kalman Filter for State Estimation of Automated Guided Vehicle in Manufacturing Environment

To navigate autonomously in a manufacturing environment Automated Guided Vehicle (AGV) needs the ability to infer its pose. This paper presents the implementation of the Extended Kalman Filter (EKF) coupled with a feedforward neural network for the Visual Simultaneous Localization and Mapping (VSLAM). The neural extended Kalman filter (NEKF) is applied on-line to model error between real and estimated robot motion. Implementation of the NEKF is achieved by using mobile robot, an experimental environment and a simple camera. By introducing neural network into the EKF estimation procedure, the quality of performance can be improved
