Published Article / This paper investigates the challenges of employing Van der Waals forces in micro-material handling since these forces are dominant in micro-material handling systems. The problems include the creation of a dust-free environment, accurate measurement of the micro-force, and the efficient picking and placing of micro-work pieces. The use of vacuum suction, micro-gripper's surface roughness, geometrical configuration and material type are presented as alternatives to overcome the challenges. An atomic force microscope is proposed for the accurate measurement of the Van der Waals force between the gripper and the micro-work piece.

This study begins with a discussion of step theory. Included in this discussion is the basis of chord succession, the idea of fundamental representation, and the uses of reinterpretation technique. These concepts are then used to demonstrate the continuity and logic of the harmonic language found in Strauss's Macbeth.

This diploma thesis deals with ownership rights to land. Due to change in legislation caused by Act No. 89/2012 Sb., Civil Code, there were many substantial changes in the area of land ownership, which have extensive impact on some of the institutes of this ownership. This thesis deals exactly with these changes and with newly or more precisely repeatedly implemented institutes of land ownership. Whole thesis aims to give some analysis of this institute with main focus on its specifics and differences. This object is fulfilled by general interpretation, which deals with characteristics of land ownership and its specifics and then it analyses some particular institutes of land ownership mainly those which were considerably changed or newly established by the ratification of the present Civil Code. Next to comparison of present and previous Czech legislation the last chapter of this thesis is devoted to comparison of Czech and German legislation.

Law of evidence is a legal-based procedure for collecting and presenting proof. The aim of the process is to follow the basic principle of legal administrative proceedings, the principle of material truth. My thesis is based on the Administrative Code regulations, although I was also pointing to the fact that there are specific regulations that restrict or exclude the use of the Administrative Code. Despite the above-mentioned, the general and theoretical ideas of the law of evidence are applicable for all administrative proceedings. Except the principle of material truth there are other basic principles of vital importance to administrative proceedings, particularly the principle of legality and the principle of working out the case without undue delay. The core of law of evidence, however, is contained in provisions of the Administrative Code dealing with the bases for a decision in the administrative proceedings at first instance. For the law of evidence in administrative proceedings it is also often applicable doctrinal and judicial knowledge of civil and criminal law, as a connecting element between these different areas of law is the principle of material truth. The decision-making practice of the administrative courts respects the similarities between criminal and administrative punishment,...

Our everyday life is becoming more active and the activities we perform influence the way we dress. Due to an increase in activities undertaken in an urban environment, demands are changing and the need for active wear that meets the new demands follow suit. The four characters represented in the research can be seen as a reflection of the functional features needed, including base layer, mid layer/insulation and shell.Despite the increase in activities, most of our clothes are still constructed on static dummies or drafted on a table in 2D and the main developments within the active sportswear field is driven by material innovation. By creating garments on a body in movement, my aim is to develop new functions and expression in active sportswear through construction.Construction methods in active sportswear are examined and understood through observations and reconstructions and constitute the foundation of a study of movement for a design recovery.The movement and features required for leading an active urban life sets the direction of the development of new func- tional garments. A series of trial and error sessions and draping fabric on a live model in movement created the prototypes used in functionality tests to establish their feasibility. The functionality of the fabric and the form needed in urban lifestyle is explored in terms of relationship to a reduced, intuitive construction to challenge the norm of aesthetics in active sportswear. Meeting the demands of the conscious urban inhabitants regarding sustainability and style challenges this further. / Program: Modedesignutbildningen

This work develops a methodology for the FEM simulation of a multi-piece crankshaft. Various simulation models that include press-fit joint contact conditions and complex meshing schemes are examined in order to accurately capture details of the stress fields present at the stress concentration area (labeled as the SCA) on the edge of the press-fit. The maximum stress components are demonstrated to be of limited values (non-singular) and Hertzian in nature. To obtain the stress convergence sufficiently small elements, which can be determined using a 2-D axisymmetric model, are required at the vicinity of the SCA. The same level of mesh refinement is then used for large 3-D FEM models of the crankshaft geometry, to study the resulting behavior of the press-fit joint for the dynamic operating loads. However, it may not always be possible or practical, as some limits on the mesh refinement have to be imposed to obtain a reasonable computational time to run such models. Less complex 'equivalent' symmetrical FEM models are investigated to determine if these models can provide a sufficient level of accuracy at an acceptable computational effort. Such models may be useful as practical design tools, producing data to speed up the decision making process. The simulation results are compared to some test data for the stress state monitored in real crankshafts under operating conditions. 'Intuitive' design sensitivities to various crankshaft parameters are examined as well. The numerical tools and engineering rules developed in the thesis may be applied to systematically improve the design by extending the joint's life and/or load carrying capability.

Le travail de thèse présenté est dédié à la mise en forme des pièces rechargées. L'idée initiale est d'inverser la gamme de fabrication " conventionnelle " consistant à recharger une pièce pré-ébauchée en faisant la mise en forme d'un " lopin " préalablement rechargé. Les avantages escomptés de cette gamme vient dans un premier temps de ce qu'on recharge une forme simple. Ceci devrait faciliter l'automatisation du rechargement et également le amélioration les structures métallurgiques de solidification issues du soudage. Les travaux concernent dans un premier temps la mise en place d'une méthodologie pour la maîtrise de l'opération de rechargement sur des formes simples pour mettre en place le lien entre le taux de dilution, l'énergie nominale de soudage et la qualité métallurgique des revêtements obtenus. Dans un deuxième temps, le travail s'est concentré sur l'étude du comportement en mise en forme des pièces rechargées. La difficulté provient du fait que le comportement du revêtement n'est pas connu. Deux essais de caractérisation ont été étudiés, le pliage à chaud et l'essai d'écrasement. Cette étude a consisté à estimer leur aptitude à évaluer la forgeabilité d'un multi matériaux concernant les trois échelles de forgeabilité: l'échelle du revêtement correspondant au comportement rhéologique du matériau du revêtement incluant sa limite de ductilité à chaud, l'échelle du revêtement incluant le revêtement et la partie proche du substrat et l'échelle de la pièce. Les simulations à partir de modèle analytique ou numérique par éléments finis ainsi que les essais expérimentaux ont permis d'évaluer la forgeabilité du bi-matériau. Les essais expérimentaux de forgeabilité devront également caractériser les transformations métallurgiques se produisant dans le revêtement et le substrat pour qualifier et quantifier le gain potentiel.

In the 19th century, ¡§Character Piece¡¨ became a new trend in piano composition. Without using large-scale formal structure, it illustrates successfully the individualities of emotional expression in music among different composers. ¡§Barcarolle¡¨¡Xfeaturing special rhythmic patterns¡Xrepresents unique elegancy and lyricism in this category. The historical development of ¡§Character Piece¡¨ in the 19th century leads as an introduction in this thesis, followed by the compositional characteristics of ¡§Barcarolle¡¨ in the second chapter. The major part of this topic focuses on ¡§Barcarolles¡¨ written by four dominant composers in the 19th Cencury: F. Mendelssohn, F. Chopin, G. Faure and S. Rachmaninoff. The stylistic comparisons include the features of form, tonality, rhythmic pattern, melodic structure, and musical texture. The detailed analytical charts are provided to show the similarities and differences among these four remarkable ¡§Barcarolles.¡¨

La thèse porte sur la synthèse d'observateurs pour les systèmes dynamiques hybrides.<br />Nous considérons particulièrement considéré les systèmes décrits par un ensemble fini de sous-systèmes linéaires à temps discret et<br />une loi de commutation. Le sous-système actif et les commutations d'un sous-système à un autre peuvent être définis par une commande externe contrôlable (systèmes à commutation), ou par des transitions autonomes (systèmes affines par morceaux). Sous<br />l'hypothèse du mode actif à chaque instant, nous montrons que l'association de l'observateur commuté avec une contrainte de<br />placement de pôles permet de proposer un schéma d'observation à entrée inconnue pour résoudre le problème de la synchronisation<br />des systèmes à commutation chaotiques avec un message incorporé. Dans le cas de des systèmes affines par morceaux, nous proposons une méthode pour détecter le mode actif. L'association de cette méthode avec l'observateur commuté permet l'estimation conjointe de l'état continu et état discret. Enfin, nous considérons le cas de commutations régies par un RdP. Nous proposons un schéma d'observation utilisant un observateur de RdP et un observateur commuté.
