3D Surface Analysis for the Automated Detection of Deformations on Automotive Panels

Yogeswaran, Arjun 16 May 2011 (has links)
This thesis examines an automated method to detect surface deformations on automotive panels for the purpose of quality control along a manufacturing assembly line. Automation in the automotive manufacturing industry is becoming more prominent, but quality control is still largely performed by human workers. Quality control is important in the context of automotive body panels as deformations can occur along the assembly line such as inadequate handling of parts or tools around a vehicle during assembly, rack storage, and shipping from subcontractors. These defects are currently identified and marked, before panels are either rectified or discarded. This work attempts to develop an automated system to detect deformations to alleviate the dependence on human workers in quality control and improve performance by increasing speed and accuracy. Some techniques make use of an ideal CAD model behaving as a master work, and panels scanned on the assembly line are compared to this model to determine the location of deformations. This thesis presents a solution for detecting deformations of various scales without a master work. It also focuses on automated analysis requiring minimal intuitive operator-set parameters and provides the ability to classify the deformations as dings, which are deformations that protrude from the surface, or dents, which are depressions into the surface. A complete automated deformation detection system is proposed, comprised of a feature extraction module, segmentation module, and classification module, which outputs the locations of deformations when provided with the 3D mesh of an automotive panel. Two feature extraction techniques are proposed. The first is a general feature extraction technique for 3D meshes using octrees for multi-resolution analysis and evaluates the amount of surface variation to locate deformations. The second is specifically designed for the purpose of deformation detection, and analyzes multi-resolution cross-sections of a 3D mesh to locate deformations based on their estimated size. The performance of the proposed automated deformation detection system, and all of its sub-modules, is tested on a set of meshes which represent differing characteristics of deformations in surface panels, including deformations of different scales. Noisy, low resolution meshes are captured from a 3D acquisition, while artificial meshes are generated to simulate ideal acquisition conditions. The proposed system shows accurate results in both ideal situations as well as non-ideal situations under the condition of noise and complex surface curvature by extracting only the deformations of interest and accurately classifying them as dings or dents.

Får- och byggnadskroppsdelar : Handlingar och spatiala relationer kring byggnadsdeponeringar på Öland / Sheep and building body parts : Actions and spatial relations regarding building deposits of sheep on Öland

Jonsson, Alexander January 2021 (has links)
Får- och byggnadskroppsdelar - Handlingar och spatiala relationer kring byggnadsdeponeringar av får på Öland. Sheep and building body parts - Actions and spatial relations regarding buildingdeposits of sheep on Öland. Abstract This essay studies ten Ölandic examples of sheep bodies or sheep body parts deposited in Iron Agebuildings. In addition to literary works, the source material examined in the essay also consists ofunpublished sources and two osteological examinations, which were carried out as a part of thework on the essay (appendix 1 & 2).The purpose of the essay is to study both the actions that become visible through the skeletalmaterial, and the possible presence of spatial patterns regarding the bone deposits. The work iscarried out using an action-theoretical approach. Furthermore, a comparative method is used toexamine the ten sites in relation to each other. The results from this are ambiguous. The thesis' mainconclusion is; 1) that the bodies of sheep was sometimes disintegrated on Öland during the IronAge, to be; 2) placed in a certain spatial proximity of the foundation of roof-supporting posts. Keywords: Öland, Iron Age, Ritual Deposits, Sheep, bodies, body parts, foundation, sacrifice, action-theory

Chápání významu somatismů v idiomech u japonských a českých mluvčích / Speakers' understanding of the meaning of names of body parts in Czech and Japanese idioms

Velká, Tereza January 2020 (has links)
The aim of this thesis is comparison of speakers' understanding of meaning of names of body parts head, eye, ear, nose, mouth and heart in Czech and Japanese language. To achieve this goal a list of idioms consisting of mentioned body parts in both languages is created. Speakers sort the idioms into arbitrary categories based on their understaing of meaning of name of body part. Resulting data is processed by multidimensional scaling and evaluated afterwards. The first bigger chapter is dedicated to introduction of idiomatics and phraseology in Europe and Japan in order to compare understanding of idioms and their classification. The second bigger chapter introduces a base for approaches to idioms, following by focus on somatic idioms. Two different approaches are introduced. The method of introspection is represented by a theory of coneptual profiles by I. Vaňková and by an idealized cognitive model of act by Arizono T. The corpus approach is represented by F. Čermák, Hashimoto Ch. et al. and by Lin W. The introduction of practical part follows. The first part is dedicated to the method of multidimensional scaling. After that the survey realization and its evaluation is described. The overall evaluation of results in terms of the aim of this thesis is placed in conclusion. Keywords: Japanese...

Lexikalischer und semantischer Wandel im Ägyptischen

Bock, Sara 29 May 2015 (has links)
Jede lebendige Sprache ist durch ihren Gebrauch ständigem Wandel unterworfen, der jede Ebene der Sprache betreffen kann – von der Phonologie über die Semantik bis hin zur Grammatik. Die vorliegende Arbeit hat es sich zur Aufgabe gemacht, den semantischen und lexikalischen Wandel des Ägyptischen zu beleuchten. Das Ägyptische ist in seinen verschiedenen Sprachstufen über mehr als vier Jahrtausende hinweg zu verfolgen, und gehört damit zu den am längsten bezeugten Einzelsprachen der Menschheitsgeschichte. Dies und die gute Quellenlage des Ägyptischen machen es zu einem prädestinierten Gegenstand für diachrone Untersuchungen. Nach einer quantitativen Erhebung der Lexeme eines ausgewählten Textkorpus’, der die Grundlage der Arbeit liefert, wurden im zweiten Teil der Dissertation vier Wortfelder exemplarisch auf ihr Wandelverhalten hin untersucht. Diese Wortfelder, Verwandtschafts- und Körperteilbezeichnungen sowie Wahrnehmungsverben und kognitive Verben, gehören zum Grundvokabular einer jeden Sprache, was die Vergleichbarkeit der Ergebnisse garantieren soll. Neben der Beschreibung konkreter Wandelphänomene wurde dabei Fragen nach dem Ablauf, dem Umfang und den Typen von semantischem und lexikalischem Wandel im Ägyptischen nachgegangen. Ziel war es unter anderem, generalisierbare Aussagen zu treffen, die für die allgemeinen Fragestellungen der Sprachwandelforschung, der Diachronen Semantik und der Historischen Linguistik von Relevanz sind, indem sie mit Ergebnissen früherer Untersuchungen zu den verschiedensten Sprachen verglichen bzw. zu ihrer Überprüfung herangezogen werden können. Als Ergebnis der Untersuchung konnten neben der Beschreibung interessanter Einzelbeobachtungen schließlich einige Regularitäten des semantischen und lexikalischen Wandels des Ägyptischen aufgestellt werden. Diese wurden zum Teil bereits durch andere Sprachen bestätigt und können nach weiterer Überprüfung möglicherweise als universale Tendenzen des semantischen Wandels formuliert werden. / Every spoken language is subject to constant change due to its use. This change can affect every level of the language, from phonology to semantics to grammar. The present dissertation is set out to illuminate the semantic and lexical change of the Egyptian language, which can be followed over four thousand years and is therefore one of the longest attested languages of mankind. This and its excellent state of sources make it the ideal subject of a diachronic study. After a quantitative analysis of the lexemes of a carefully chosen set of texts, which provides the foundation of the study, the main part of the dissertation examines four semantic fields with regard to its mode of change. These semantic fields, kinship terms and terms for body parts as well as verbs for cognition and perception, are part of the basic vocabulary of every language, which guarantees the comparability of the results. In addition to the description of individual processes of change, the paper pursues questions of the course, the range, and the types of semantic and lexical change of the Egyptian language. The intention was to form general statements which are of relevance to questions of the study of language change, the Diachronic Semantics as well as the Historical Linguistics, by serving as comparison as well as verification to studies of other languages. As a result of the present paper, some general regularities of the semantic and lexical change of the Egyptian language were established, in addition to the observation of some interesting individual processes of language change. These regularities were already partially confirmed by observations made in other languages and could, after further examination, turn out to be universal tendencies of semantic change.

L'influence du droit de la santé sur le droit extra-patrimonial de la famille : repenser le droit français à la lumière du droit suisse / The influence of health law on extrapatrimonial family law

Cappellari, Anaëlle 09 December 2014 (has links)
Le droit de la santé réglemente les actions de santé lato sensu. En encadrant juridiquement une pluralité d'actes médicaux, comme l'AMP, l'interruption de grossesse, l'examen des empreintes génétiques ou encore les dons d'éléments et produits du corps humain, il influence le droit extra-patrimonial de la famille. Cette influence est protéiforme et se manifeste à la fois sur la détermination des liens familiaux et sur les droits et devoirs en découlant. Le droit comparé franco-suisse, dans sa fonction de connaissance du droit, permet de révéler les manifestations de cette influence. Le droit de la santé français exerce fréquemment un rôle moteur, subversif des concepts civilistes traditionnels. Le droit de la santé et le droit de la famille sont le plus souvent pensés séparément, le premier tendant parfois à s'autonomiser. À l'inverse, le droit de la santé suisse s'inspire régulièrement des constructions civilistes préexistantes, même si la finalité sanitaire justifie parfois un renouvellement des concepts. Ainsi, les deux champs du droit sont le plus souvent pensés globalement, approche dont le droit français gagnerait à s'inspirer. L'influence du droit de la santé sur le droit extra-patrimonial de la famille doit être repensée en tenant compte des objectifs poursuivis par les différentes règles de droit. La spécificité des actes médicaux à finalité familiale justifie que le droit de la santé soit cantonné à un rôle technique, suiveur de l'évolution du droit de la famille. En revanche, lorsqu'il réglemente les actes médicaux susceptibles d'influencer les droits et devoirs familiaux, le droit de la santé peut exercer un rôle complémentaire à celui du droit de la famille. / Health law regulates medical activity. By giving a legal framework to several medical acts, such as ART, abortion, DNA identification or donations of components and products of the human body, it influences extrapatrimonial family law. This influence is undeniably protean as it is exerted on both the definition and the legal regime of family ties. In its quest for improving knowledge of legal systems, French-Swiss comparative law can reveal and explain the manner in which this influence is expressed. In France, health law often plays a leading role, thus subverting traditional family law concepts and sometimes leading to inconsistencies. Health law and family law are usually viewed separately, with health law often taking an autonomous stance. In Switzerland, on the other hand, health law frequently draws on preexisting civil and family law concepts. Most of the time, these two fields of law are thought of together. This analysis incites us to rebuild French law in the light of Swiss law. The influence of health law on extrapatrimonial family law must be rethought, by taking into account the goal of each legal rule. The specificity of medical acts pursuing family interests justifies confining health law to a technical role, following the evolution of family law. Health law must be a tool for family law. However, health law can complement family law when it comes to the determination of family rights and duties. This complementarity is expressed either through the articulation of both branches of law when common goals are visible, or through the search for criteria capable of reconciling the conflicting goals pursued by these two subjects.

Acculturation in African American College Women and Correlates of Eating Disorders

Lester, Regan 08 1900 (has links)
Although eating disorders have been the focus of much research, the inclusion of minority populations has been minimal. A recent review of the literature by Dolan (1991) has found that eating disorders were most likely to be present in non-White women who were exposed to Western societies and cultures. Thus, the purpose of this study was to examine personality, physical, and cultural correlates of bulimic symptomatology in a sample of African American college women. The Bulimia Test Revised (BULIT-R) was used to assess bulimia symptoms. The African American Acculturation Scale (AAAS), the Beliefs about Attractiveness Scale Revised (BAAR factors 1 and 2), the Rosenberg Self-Esteem Scale (SES), the Centers for Epidemiological Depression Scale (CES-D), Body Parts Satisfaction Scale (BPSS), and body mass were the independent variables hypothesized to predict bulimic symptoms. Hierarchical regression analysis revealed that body mass, depression, and low self-esteem were the best predictors of bulimic symptomatology, together accounting for 38% of the variance. Beliefs about attractiveness and body satisfaction were related to bulimic symptoms but not when considered simultaneously with the other variables. Acculturation was not predictive of bulimic symptoms. 0-ordered correlations revealed that beliefs about attractiveness and body satisfaction were correlated with bulimic symptoms. Acculturation was not related to any variables except depression. Implications for counseling interventions as well as directions for future research are discussed.
