Organisering av arméns insatsorganisation : Är det operativa och taktiska skäl till att förbanden ser ut som de gör?

Peters, Jörgen January 2010 (has links)
Uppsatsens syfte är att analysera och diskutera vad som legat till grund för organisering av arméns insatsförband insatsorganisations år 2009 (IO 09). Hur ser organisationsstrukturen ut och vilka faktorer har påverkat organiseringen av IO 09? Uppgiftens komplexitet innebar att jag närmade mig problemformuleringen från olika perspektiv. Studien omfattar därmed en mångsidig kvalitativ analys av data från både styrdokument och intervjuer. Studien visar att det framförallt är de klassiska ”byråkratiska teoretiska” perspektiven som dominerar organisationsdesignen inom arméns insatsorganisation 2009. Vidare förefaller det finnas en arketyp för hur ett förband i armén skall vara organiserat. Denna arketyp omfattas sannolikt av en organisationsstruktur om fyra ledningsnivåer och ett kontrollspann om fyra eller fem enheter i alla nivåer. Signifikant för maskinbyråkratimodellen, vilken identifierats i nio av tio organisationsstrukturer i IO 09, är att denna organisationsdesign underlättar tydliga och klara ledningsförhållanden. Däremot har maskinbyråkratimodellen en del nackdelar såsom att modellen anses vara rigid och svår att förändra. Studien konstaterar därmed en intressant paradox d.v.s. kravet på att organisationerna i IO 09 skall vara modulära och flexibla samtidigt som organisationsstrukturerna i IO 09 antyder något annat. Ett annat resultat som studien visar är att det framförallt synes varit mänskliga faktorer tillsammans med omgivningskaraktäristiska faktorer som dominerat ”processerna” i organiseringen av IO 09, därmed också i allra högsta grad resultatet av hur arméns insatsorganisation 2009 är organiserad. / The purpose of this essay is to analyse and discuss what has been the basis of the organization of the mission-based armed forces in the year of the mission-based organization 2009 (IO 09). What does the organizational structure look like and what factors have affected the organization of IO 09? The complexity of the task demanded an approach to problem formulation from various perspectives. Thus, the study includes a diversified qualitative analysis of data collected from governing documents as well as interviews. The study shows that, above all, it is the classic “bureaucratic theoretical” perspectives that dominate the organizational design within the mission-based organization 2009. Furthermore, there seems to exist an archetype with respect to how an army force battalion unit should be organized. This archetype does most likely represent an organizational structure comprised of four levels of leadership and a span of control of four or five units operating at all levels. Significant to the machine bureaucracy model, which has been identified in nine out of ten organizational structures in IO 09, is that this organizational design facilitates distinct and clear leadership conditions. However, the machine bureaucracy model demonstrates some disadvantages such as the fact that it is considered to be rigid and difficult to change. Hence, the study reveals an interesting paradox, that is, the requirements stipulated for the organizations in IO 09 are supposed to be modular and flexible while the organizational structures in IO 09 suggest something else. An additional result showed by the study is that, primarily, it appears that human factors combined with environmental characteristic factors have dominated the “processes” with regard to the organization of IO 09. Consequently, these factors have also seem to generated the outcome with regard to how the army’s mission-based organization 2009 has been organized.

Frequency Domain Analysis of Composite Long-Span Cable-Stayed Bridges by Finite Strip Method

Li, Haoran January 2017 (has links)
The finite strip method (FSM) is a very efficient numerical method employed for performing the structural analysis of slender structures, such as cable-stayed bridges; the strip discretization of the model allows for the usage of a lower number of degrees of freedom, in comparison with the finite element method (FEM), while, as it will be discussed in the current research, the results obtained from both methods are in relatively good agreement. Moreover, to address the latest developments in the area of smart construction materials used for long-span bridges, the fiber reinforced polymer (FRP) composites were implemented for the bridge deck modeling, as part of a hybrid composite FRP cable-stayed bridge, and an extend laminate integrated finite strip method (LFSM) was applied for estimating the static structural performance of the hybrid composite FRP long-span cable-stayed bridge under several concentrated and uniformly distributed loadings. The free vibrations analysis was conducted for the Kap Shui Mun Cable-stayed Bridge model, and the natural frequencies were compared with the ones obtained from an FE model of the same bridge. One of the advantages of using the integrated finite strip method is that number of vibration modes, which can be included in the dynamic analysis when the effect of a sweeping sinus and a seismic loading are investigated when a conventional FE analysis would fail to converge. The outcomes of this research will set the stage for the hybrid long-span cable-stayed bridges modeling by the laminate integrated finite strip method (LFSM) which is more efficient and straightforward than the finite element analysis, for performing the static, free vibration, time domain, and frequency domain analyses.

Galerie letecké techniky a tradic letectví na letišti Medlánky v Brně / Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno

Rebrova, Tatiana January 2016 (has links)
Area of the airport Medlánky is situated on the border of city districts Brno-Medlánky and Brno-Komín near the nature reserve "Medlánecké kopce". The designed gallery of aviation is a two-storey building, which consists of three parts. The main part is the exhibition space for airplanes, which is formed of a single-storey long-span hall, with the two-storey entrance part of the complex of buildings connected to it, in which are situated the area of the entrance, the training center (detached workplace of the institute of aviation FS BUT in Brno) and the administration. In the building of the original hangar, which is located along the street Turistická are located restaurants and aeroclub. Exhibition hall of the building of the gallery is formed by the structural system of the arched wooden glulam beams. The load-bearing wooden structures are visible and form the elements of the interior of the exhibition space. Two-storey extention of the entrance part of the building is structurally designed as a skeleton wooden structure. The material exception is the area of the entrance, which is made of monolithic concrete.

Mostový jeřáb jednonosníkový / Bridge crane one-girder

Chroust, Martin January 2018 (has links)
The focus of this thesis is the construction of a single girder overhead crane. The goal is to render a crane construction according to preset parameters. The parameters include a lifting power of 8,000 kg, a 10,000 mm reach, a 2,400 mm wheelbase and a stroke of 8,000 mm. The thesis includes brief theoretical research focused on overhead cranes, their various types and description of their main components. Brief description of chosen parameters for the construction itself follows. The description of chosen parameters includes calculations of strain acting during operation, technical and stability parameters, essential for the construction. All calculations were made with regard to valid Czech technical standards and specialized literature which focuses on the construction of cranes and their parts. Finally, the thesis is extended by the required technical drawings.

Saini, Ratni, Boland, Sebastian, Kataeva, Olga, Schmidt, Arndt W., Kurzchalia, Teymuras V., Knölker, Hans-Joachim January 2012 (has links)
A stereoselective synthesis of (25S)-Δ1-, (25S)-Δ1,4-, (25S)-Δ1,7-, (25S)-Δ8(14)-, (25S)-Δ4,6,8(14)-dafachronic acid, methyl (25S)-Δ1,4-dafachronate and (25S)-5α-hydroxy-3,6-dioxocholest-7-en-26-oic acid is described. (25S)-Δ1,4-Dafachronic acid and its methyl ester are natural products isolated from corals and have been obtained by synthesis for the first time. (25S)-5α-Hydroxy-3,6-dioxocholest-7-en-26-oic acid represents a promising synthetic precursor for cytotoxic marine steroids. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.
