Abstract:

Printed circuit boards used in most ordinary electrical devices are usually equipped through an assembly line. Pick and place machines as part of those lines require accurate detection of incorrectly picked components, and this is commonly performed via image analysis. The goal of this project is to investigate if we can achieve state-of-the-art performance in an industrial quality assurance task through the application of artificial neural networks. Experiments regarding different network architectures and data modifications are conducted to achieve precise image classification. Although the

Abstract:

In recent years the control of tool vibration has emerged as the critical area of scientific development. This is because tool vibration creates sound-noise and unwanted quality surface. Mathematically, the observed tool vibration is a ratio of the force acting on the tool to its dynamic stiffness. Because dynamic stiffness is strongly influence by tool damping, the tool vibration could be controlled by enhancing the damping ability of the tooling system. The Department of Production Engineering at KTH has designed new damped drilling tools which absorb the vibratory energy from machining. It

Abstract:

\(\beta\)-barrel membrane proteins perform important functions in the outer membranes of Gram-negative bacteria and in the mitochondria and chloroplasts of eukaryotes. Cellular machines that have been conserved from bacteria to humans assemble these proteins by an unknown mechanism. The components of the \(\beta\)-barrel assembly machine (Bam) in E. coli have been identified, but it has been difficult to study their function in vivo because they catalyze an essential process; mutations in proteins involved in the assembly pathway are often lethal or produce pleiotropic phenotypes that do not r

The traditional product development process has been sequential in nature, with the product going through design, process planning, manufacturing and assembly. This sequential decision making results in increased costs and higher product development times. With the trend towards better product quality, product customization, shorter product life cycle, and international competition, manufacturers are faced with the challenge of improving product quality while reducing product development time, manufacturing lead-time, and product cost. To cope with these challenges, the product development pro

Abstract:

Since the emergence of the object technology, organizations have accumulated a tremendous amount of object-oriented (OO) code. Instead of continuing to recreate components similar to existing artifacts, and considering the rising costs of development, many organizations would like to decrease software development costs and cycle time by reusing existing OO components. The difficulty of finding reusable components is that reuse is a complex and thus less quantifiable measure. In this research, we first proposed three reuse hypotheses about the impact of three internal characteristics (inheritan

The hard equation of railway safety versus the high commercial profits can only be achieved through the use of new inspection methods supported by modern technologies. The track and its components can have different types of troubles, such as rail surface defects, broken sleepers, missing fasteners, and irregular ballast levels. Each component of the track infrastructure plays a significant role, where the failure or the absence of any of them can pave the way to undesired situations. The rail is designed to carry and direct the train, the sleepers are meant to maintain the level of the rail,

The repair of worn or damaged components is becoming more attractive to manufacturers, since it enables them to save resources, like raw material and energy. With that costs can be reduced, and profit can be maximised. When enabling the re-use of components, the lifetime of a component can be extended, which leads to improved sustainability measures. However, repair is not applied widely, mainly because costs of repairing are overreaching the costs of purchasing a new component. One of the biggest expense factors of repairing a metal component is the labourintense part of identifying and quant

Abstract:

It is now a common sense that manufactures including machine suppliers and system integrators of the 21 st century will need to compete on global marketplaces, which are frequently shifting and fragmenting, with new technologies continuously emerging. Future production machines and manufacturing systems need to offer the "agility" required in providing responsiveness to product changes and the ability to reconfigure. The primary aim for this research is to advance studies in machine control system design, in the context of the European project VIR-ENG - "Integrated Design, Simulation and Distr

Abstract:

The aim of this master thesis is the construction of a single-purpose semi-automatic machine to assembly a component of a car. The component of assemble is a device to refueling, which consists of more thermoplastic parts. It is used a knowledge of 3D modeling software, solution of construction assemblies and necessary calculations to design the machine. The result of this thesis is detailed 3D model and drawing documentation of designed assembly machine.

Abstract:

O objetivo principal desta tese consiste no desenvolvimento de ferramentas matemáticas e computacionais dedicadas a um sistema de diagnóstico de barras quebradas no rotor de Motores de Indução Trifásicos. O sistema proposto é baseado em um método matemático de decomposição de sinais elétricos, denominado de Decomposição em Componentes Ortogonais, e ferramentas de aprendizagem de máquinas. Como uma das principais contribuições desta pesquisa, realizou-se um aprofundamento do entendimento da técnica de Decomposição em Componentes Ortogonais e de sua aplicabilidade como ferramenta de processament

Abstract:

This research develops an analytical scientific approach for investigating the high precision surface generation and the quantitative analysis of the effects of direct factors in precision machining. The research focuses on 3D surface characterization with particular reference to the turning process and associated surface generation. The most important issue for this research is surface functionality which is becoming important in the current engineering industry. The surface functionality should match with the characterization parameters of the machined surface, which can be expressed in form

Abstract:

La (Pcdh15) est localisée dans les touffes ciliaires des cellules ciliées internes et externes de la cochlée. Elle forme des liens interstéréociliaires entre les différents stéréocils, des protrusions riches en actine qui forment ensemble la touffe ciliaire. L’absence de Pcdh15 entraîne la désorganisation des touffes ciliaires et la perte de la mécanotransduction auditive. Pcdh15 forme en effet la partie basse du lien de bout de cil (en anglais tip-link), le lien contrôlant l’ouverture du canal de transduction, qui se situe au point d’insertion inferieur de ce lien.
