Návrh podvozku malého dvoumístného letounu / Landing gear design of two-seat airplane

Čavojský, Tomáš January 2021 (has links)
This diploma thesis deals with the landing gear design of the small two-seat aircraft. The introduction focuses on the conceptual gear design and shock absorber computational dynamic characteristic model. The practical part is focused on the landing gear construction according to the selected parameters based on the conceptual and computational model. The diploma thesis ends with strength calculations and production documentation.

Jeřábová kočka 130/50 t / Crane crab 130/50 t

Basista, Filip January 2008 (has links)
The main goal of this dissertation is to design and to calculate chosen parts of a crab of a foundry travelling crane according to assigned parameters. The foundry crane provides transport of a casting ladle, which is hanged with a girder on a double hook of the main stroke. Except the main travel, the crane crab includes more an auxiliary stroke. The whole work is divided to two parts. The first part (calculating) is aimed mainly to calculation of both strokes and a travel. The second one (drawing) contains a drawing of the crane crab and drawings of a rope drum of the main stroke.

Předběžný návrh malého dvoumístného vrtulníku / Preliminary Design of a Small Two Seat Helicopter

Junas, Milan January 2016 (has links)
The thesis deals the preliminary draft of the small two-seat helicopter with a piston engine. The aim of the thesis is not to propose a helicopter across the extent of the problems. Therefore we have chosen only selected issues which can be managed in the range of work. The introduction is focused on defining the general requirements imposed on proposed helicopter, formulating the basic conceptual and structural design according to the building regulation the relevant category. These ranges create a based assumption for right evaluation of the statistical analysis of the helicopters of the same or very near parameters category. Subsequently, there were defined the basic parameters of the proposed helicopter which make possible to solve the performance characteristics in the vertical and backward flight. The work is also focused on design of the rotor head of main rotor for the proposed helicopter, the definition of load acting on the rotor head, waving analysis and calculation of centrifugal forces acting on the main rotor blades. The design of the rotor head and also the helicopter as a whole will be graphically processed in the program Dassault Systemes Catia.

Characterizing Subsurface Structure of Two Contrasting Sites in the Main Ethiopian Rift

Hansson, Ebba January 2019 (has links)
The Main Ethiopian Rift is a part of the East African Rift, from where the African plate is being teared apart and separated from the Indian and the Arabian plate. Even though earthquakes in this area are relatively less frequent, the subsurface structure is a subject of big research interest, since information about the subsurface layers has considerable relevance when it comes to site amplication related to earthquakes. The aim of this project is to map and compare the subsurface structures of two sites located in the Ethiopian Rift, using seismic refraction technique. By looking at the first arrivals of artificial seismic waves on a designated site, the velocities as well as the thicknessof the subsurface layers can be obtained. The result showed that the both sites contained a low velocity structure which contained weathered material.

La perception de la performance et de ses déterminants dans les Réseaux Territorialisés d’Organisations : une étude de cas des places portuaires de commerce françaises / The perception of performance and its determinants in clusters : a case study of French seaports

Desplebin, Olivier 19 November 2015 (has links)
La recherche vise à appréhender la perception de la notion de performance par les acteurs composants les Réseaux Territorialisés d’Organisations (RTO), non pilotés par une firme leader, mais comportant des instances de gouvernance stratégique. Malgré une littérature abondante portant sur les RTO, les recherches portant sur la perception de leur performance sont encore émergentes. Soutenue par un cadre interprétatif visant à clarifier ce que peut recouvrir le concept de performance dans un RTO, la recherche, mobilisant la théorie des représentations sociales, explore au moyen de la méthodologie des cartes cognitives les perceptions d’acteurs hétérogènes composant les RTO portuaires français. 36 entretiens ont été menés auprès des acteurs des Grands Ports Maritimes français. Les résultats montrent principalement qu’il existe des représentations partagées assez limitées du point de vue des métas-critères et déterminants de performance, avec toutefois l’existence de logiques communes, déclinées en paradigmes et classes de représentations. Les résultats montrent également la focalisation fréquente des perceptions sur un très faible nombre d’acteurs clés de la chaîne servicielle. L’étude conclut sur les perspectives pour le contrôle de gestion dans ces RTO. / The research aims to understand the perception of the performance concept by cluster actors. We focus on clusters which are not controlled by a leading firm, but include strategic governance institutions. Despite a vast literature on clusters, researches on the perception of their performance are still emerging. Supported by an interpretative framework to clarify what can cover the concept of performance in a cluster, this research, mobilizing social representation theory, explores the perception of heterogeneous actors composing French seaports, using the methodology of cognitive maps. 36 interviews were conducted with participants of the main French Seaports. The results show that the shared representations are fairly limited in terms of meta-criterias and performance determinants, but identifies common logics, paradigms and representations classes. The results also show that there is a frequent focalisation of the perceptions on very few keys actors involved in the service chain. The study concludes on the management control perspectives in these clusters.

Learning in Architecture

Tyupkina, Maryana 02 November 1999 (has links)
Two entities, town and university, each playing different functional roles, different in scale and structure, come together at one point. The architecture of that point is a transitional condition. Each element has integrity on its own, and at the same time is a part of the system. The primary requirement for the architecture of this place is to be elegant and thoughtful. This idea is addressed in five scales within the project: the axis, the street, the paths, the wall, and the room. / Master of Architecture
