To comply with the proposal of the dissertation, will be need to understand a little about the period in which Julian ruled Rome, known as Dominato. From a periodization suggested in this paper, we seek to identify the characteristics of the political system and the importance of such research for the analysis of Julian's empire. Then we will make a brief biographical research on the sovereign comprising all his philosophical, political and religious formation, so we can understand densely their political and religious goals to become emperor. We used as the main source a hymn in devotion to the sun god, Helios, designed by Julian in Greek and translated into English by Wilmer Wright. Within the dynamics of research, the work seeks to avoid its hypothesis that the emperor followed the god Mithras, solar deity Indo-Iranian. The dissertation presents an analysis of the two deities separately, so you can identify which Julian followed suit. Made these studies, will we can reach the main hypothesis of this study was to identify the political transformation that Julian sought to achieve from a religious perspective based on the solar-worship / O presente trabalho tem por objetivo analisar as a??es pol?tico-religiosas do imperador romano Fl?vio Cl?udio Juliano (361 ? 363 d.

A partir de uma periodiza??o sugerida neste texto, buscamos identificar quais as caracter?sticas desse sistema pol?tico e qual a import?ncia dessa investiga??o para a an?lise do imp?rio de Juliano. Faremos, ent?o, uma breve pesquisa biogr?fica sobre o soberano, compreendendo toda sua forma??o filos?fica, pol?tica e religiosa, para que, assim, possamos compreender densamente seus objetivos pol?tico-religiosos ao se tornar imperador. Utilizamos como fonte principal um hino em devo??o ao deus do Sol, H?lios, elaborado em grego por Juliano e traduzido para o ingl?s por Wilmer Wright. Dentro da din?mica da pesquisa, o trabalho busca se desvincular da hip?tese de que o imperador seguia o deus Mitra, divindade solar indo-iraniana. A disserta??o prop?e uma an?lise das duas divindades separadamente, para que seja poss?vel identificar qual delas Juliano seguia de fato. Feito estes estudos, poderemos chegar a principal hip?tese deste trabalho: identificar a transforma??o pol?tica que Juliano procurava realizar a partir de uma perspectiva religiosa com base no culto solar

The viability of small Unmanned Aerial Vehicles (UAVs) as a stable platform for specific application use has been significantly advanced in recent years. Initial focus of lightweight UAV development was to create a craft capable of stable and controllable flight. This is largely a solved problem. Currently, the field has progressed to the point that unmanned aircraft can be carried in a backpack, launched by hand, weigh only a few pounds and be capable of navigating through unrestricted airspace. The most basic use of a UAV is to visually observe the environment and use that information to influence decision making. Previous attempts at using visual information to control a small UAV used an off-board approach where the video stream from an onboard camera was transmitted down to a ground station for processing and decision making. These attempts achieved limited results as the two-way transmission time introduced unacceptable amounts of latency into time-sensitive control algorithms. Onboard image processing offers a low-latency solution that will avoid the negative effects of two-way communication to a ground station. The first part of this thesis will show that onboard visual processing is capable of meeting the real-time control demands of an autonomous vehicle, which will also include the evaluation of potential onboard computing platforms. FPGA-based image processing will be shown to be the ideal technology for lightweight unmanned aircraft. The second part of this thesis will focus on the exact onboard vision system implementation for two proof-of-concept applications. The first application describes the use of machine vision algorithms to locate and track a target landing site for a UAV. GPS guidance was insufficient for this task. A vision system was utilized to localize the target site during approach and provide course correction updates to the UAV. The second application describes a feature detection and tracking sub-system that can be used in higher level application algorithms.

Le dieu Sol, personnification de l’astre du jour, est documenté à Rome et en Italie bien avant l’avènement de l’empire. Dieu longtemps secondaire, ce n’est que durant l’Antiquité tardive qu’il gagne en importance, mais jamais au point de supplanter Jupiter et de devenir la divinité suprême. Cette étude a pour but d’offrir une approche renouvelée de l’interprétation de son image, en mettant en valeur la constance de son iconographie, l’uniformité des messages qui lui sont associés, son importance croissante dans l’idéologie politique impériale, et ensuite de les expliquer et de les réintégrer dans une perspective plus globale du IIe au IVe siècle. Cette présente thèse a ainsi pour but d’étudier les représentations du dieu Sol, à la fois personne divine et personnification de l’astre diurne, puis d’en déduire la nature du pouvoir cosmique du dieu, notamment par l’étude des documents dans lesquels il est mis en relation directe ou indirecte avec d’autres divinités, et de mettre en relief la spécificité de l’utilisation de l’image du dieu Sol dans un contexte impérial. / The Sun deity was documented in Rome and in Italy well before the advent of the Empire. Considered secondary for a long time, this god’s importance grows only during the late Antiquity.This study aims at offering a renewed approach of its image by emphasizing the constancy of its iconography, the uniformity of the messages associated to it, and its increasing importance in the imperial political ideology which we are to explain and place in a more global perspective from the 2nd to the 4th century.Within this thesis we will study the representations of the Sun deity, as a god and as the personification of the sun. From the analysis of its documented relationship to other divinities we will establish its cosmic power and the particular use of its image in an imperial context.

The curiosity of researchers to find novel characteristics and properties of matter constantly pushes for the development of instrumentation based on X-radiation. I present in this thesis techniques for electron spectroscopy based on developments of X-ray sources both in time structure and energy. One part describes a laser driven High-Harmonic Generation source and the application of an off-plane grating monochromator with additional beamlines and spectrometers. In initial experiments, the source is capable of producing harmonics between the 13th and 23rd of the fundamental laser 800 nm wavelength. The intensity in the 19th harmonic, after monochromatization, was measured to be above 1.2·1010 photons/second with a repetition rate of 5 kHz.  The development of a chopper system synchronized to the bunch clock of an electron storage ring is also presented. The system can be used to adjust the repetition rate of a synchrotron radiation beam to values between 10 and 120 kHz, or for the modulation of continuous sources. The application of the system to both time of flight spectroscopy and laser pump X-ray probe spectroscopy is shown. It was possible to measure triple ionization of Kr and in applied studies the valence band of a laser excited dye-sensitized solar cell interface. The combination of the latter technique with transient absorption measurements is proposed. The organic molecule maleic anhydride (MA) and its binding configuration to the three anatase TiO2 crystals (101), (100), (001) has been investigated by means of Xray Photoelectron Spectroscopy (XPS) and Near Edge X-ray Absorption Fine structure Spectroscopy (NEXAFS). The results provide information on the binding configuration to the 101 crystal. High Kinetic Energy Photoelectron Spectroscopy was used to investigate multilayers of complexes of iron, ruthenium and osmium. The benefit of hard X-rays for ex-situ prepared samples is demonstrated together with the application of resonant valence band measurements to these molecules.

The main aim of this thesis is to evaluate the use of Helios Orange in the context of a specific company. The thesis is divided into two parts, a theoretical and a practical one. The theoretical part describes the history of accounting and developments in the technology of bookkeeping, the development of ERP systems, related legislation and selected possibilities of electronic data interchange. In the practical part, the company PNEU PROCHÁZKA s.r.o. is firstly described. Selected most used modules of Helios Orange are then further discribed and evaluated including the possibilities of change in their use.

This thesis deals with the analysis of the information system software of the EKOFILTR spol. s r.o. company. The aim of the thesis is to propose certain steps and adjustments that would make the system more efficient and generally more user-friendly. The thesis consists of three parts. The first part is devoted to description of terms and procedures that form the basis of the analysis of information system. Analysis itself is carried out in the next section. Here, identified system deficiencies are described as well as processes which led to their detection. The last part is then devoted to solving these problems through specific proposals.

Stereo vision is a very useful, yet challenging technology for a wide variety of applications. One of the greatest challenges is meeting the computational demands of stereo vision applications that require real-time performance. The FPGA (Field Programmable Gate Array) is a readily-available technology that allows many stereo vision methods to be implemented while meeting the strict real-time performance requirements of some applications. Some of the best results have been obtained using non-parametric stereo correlation methods, such as the rank and census transform. Yet relatively little work has been done to study these methods or to propose new algorithms based on the same principles for improved stereo correlation accuracy or reduced resource requirements. This dissertation describes the sparse census and sparse rank transforms, which significantly reduce the cost of implementation while maintaining and in some case improving correlation accuracy. This dissertation also proposes the generalized census and generalized rank transforms, which opens up a new class of stereo vision transforms and allows the stereo system to be even more optimized, often reducing the hardware resource requirements. The proposed stereo methods are analyzed, providing both quantitative and qualitative results for comparison to existing algorithms. These results show that the computational complexity of local stereo methods can be significantly reduced while maintaining very good correlation accuracy. A hardware architecture for the implementation of the proposed algorithms is also described and the actual resource requirements for the algorithms are presented. These results confirm that dramatic reductions in hardware resource requirements can be achieved while maintaining high stereo correlation accuracy. This work proposes the multi-bit census, which provides improved pixel discrimination as compared to the census, and leads to improved correlation accuracy with some stereo configurations. A rotation-invariant census transform is also proposed and can be used in applications where image rotation is possible.

Magnetism is a familiar phenomenon, and is applied in a variety of devices, from simple ones, like compasses, to the more sophisticated magnetic hard disk drives. It is also known that the magnetization of a material can change, for example by heating or by exposure to an external magnetic field. The dynamics of transitions between different magnetizations, however, is largely unknown, particularly in complex materials. To further the understanding of such dynamics, this thesis presents an observational study of the dynamics of laser induced demagnetization of permalloy (Ni0.8Fe0.2). Dynamics were studied with element-specificity, i.e. Fe and Ni were studied simultaneously, but separately, rather than studying the overall material. The study was conducted at the HELIOS laboratory at Uppsala University, which features equipment for the study of magnetization dynamics. Important concepts like high-order harmonic generation (HHG) and the transverse magneto-optic Kerr effect (T-MOKE) are discussed. HHG is the laser induced generation of high energy photons, and T-MOKE relates the intensity of reflected light to the magnetization of the reflecting material. The study revealed a very short demagnetization time, and maximum demagnetization of both elements was achieved within 1 picosecond. An onset delay in the demagnetizations of Fe and Ni of about 25 femtoseconds was also observed. Both phenomena have been previously reported. The results further imply that the magnetizations diverge over a 10 picosecond time interval after the onset of demagnetization, which has not been previously reported. The apparent divergence may be due to an unknown transient setup-related issue. The short demagnetization times, as well as the onset delay could potentially contribute to the development of a more complete theory of magnetization dynamics. / Magnetism är ett bekant fenomen, som utnyttjas i allt från enkla tillämpningar, som kompasser,till mer sofistikerade sådana, som hårddiskar. Det är också känt att magnetiseringen i ett material kan ändras, t.ex. genom upphettning eller genom att det utsätts för ett yttremagnetiskt fält. Dynamiken vid övergångar mellan olika magnetiseringstillstånd är dock ett relativt okänt ämne, i synnerhet när det kommer till komplexa material. För främjandet av en större förståelse inom ämnet, presenteras här en observationell studie av dynamiken för laserinducerad avmagnetisering av permalloy (Ni0.8Fe0.2). Dynamiken undersöktes med grundämnesspecificitet, d.v.s. Fe och Ni undersöktes samtidigt, men var för sig, snarare än att materialet undersöktes som helhet. Undersökningen gjordes vid HELIOS-laboratoriet vid Uppsala Universitet, som tillhandahåller utrustning för undersökning av magnetiseringsdynamik. Viktiga koncept diskuteras, såsom övertonsgenerering och den transversella magnetooptiska Kerr-effekten (T-MOKE). Övertonsgenerering innebär laserinducerad generering av högenergifotoner, och T-MOKE relaterar reflekterad intensitet till magnetiseringen i det reflekterande materialet. Undersökningen påvisade en mycket kort avmagnetiseringstid, och maximal avmagnetisering nåddes inom en pikosekund. En relativ tidsförskjutning mellan avmagnetiseringsförloppen för Fe och Ni om ungefär 25 femtosekunder observerades också. Båda fenomen har rapporterats tidigare. Resultatet visar även en divergens mellan magnetiseringsförloppen under ett tidsspann på 10 pikosekunder efter avmagnetiseringens början, vilket inte har rapporterats förr. Den skenbara divergensen kan bero på ett okänt, tillfälligt problem i uppställningen. Den korta avmagnetiseringstiden och den relativa tidsförskjutningen skulle kunna bidra till utvecklingen av en mer komplett teori för magnetiseringsdynamik.
