The inspiration of the thesis stands on general insufficient condition of the presentation of financial management and state budget for the public sector of the Czech Republic. Thesis deals with the presentation of selected accounting and financial information from the system CSÚIS and using selected open source BI technology for this purpose. The input is a data extract from the central state accounting information system (CSÚIS), which contains accounting records and financial statements of public entities. Logical data model created by using data obtained is followed by the proposed budget options data analysis and accounting at both the state and at a particular entity level. The next phase of work trying to implement the project requirements of open source Business Intelligence technologies (OSBI). The work includes market analysis of OSBI, and chooses the most appropriate tool to build the new presentation of state financial and accounting data.

In the field of robotics, quadrupedal robotics is a rapidly growing segment. Despite the large number of robotic quadrupeds developed so far, there is currently no platform specifically developed for use in an educational setting. Currently available quadrupeds have several aspects that restrict them to use only in the research labs that developed them, preventing them from being available for use in undergraduate-level classes. This constraint limits the number of people able to gain experience with these highly complex platforms. To enable further development into the field of quadruped robotics, more engineers with in-depth experience with these platforms and the knowledge required to develop and operate them are needed. In this thesis we present the SmallKat platform which strives to fill this space and allow for further development into the fields of dynamic quadruped robotics without the fear of damaging an expensive robot. This thesis proposes a robot designed specifically for the purpose of teaching multiple robotics concepts including kinematics, control, dynamics, trajectory planning, and gait generation. Like many other quadrupedal robots, SmallKat uses 3-DoF legs allowing for coordinated motion in all 3 axes. The size, modularity, cost, and capabilities of the platform are what suit it to teach at a variety of levels. With the integrated sensing and safety features, this platform lends itself to the development of an undergraduate robotics course on quadruped robots, a sample of which is discussed in this thesis. Through the distribution of the SmallKat robot to more schools and universities, the robotics curriculum offered by these universities could be expanded further to offer courses at the undergraduate level in legged robotics.

The main point of this work is to describe complex solution of web-hosting server based on free software. This should provide main services such a post or www server. The work describes instalation of Unix(GNU/Linux) operating system. In addition are described individual services, evolved conrete implementations and also is spoken their installation and configuration. Though this text describe implementation of concrete application, some part of thist text contains generally information about installation, configuration and securing of linux servers.

Die vorliegende Bachelorarbeit betrachtet die individuellen Anforderungen der Bibliothek des Bundesverwaltungsgerichts in Leipzig an eine neue Bibliothekssoftware. Neben dem jetzigen System aDIS/BMS soll das Open Source System Koha näher beleuchtet werden. Die Anforderungen an eine neue Software werden auf der Grundlage von sechs leitfadengestützten Experten-Interviews definiert, die mit den Mitarbeitenden der Bibliothek geführt wurden. Daraufhin wird ein Entwurf von Lasten- und Pflichtenheft entwickelt, in dem Kriterien nach Relevanz gewichtet werden. Anhand dessen und mithilfe eines Punktesystems werden die Funktionen der ausgewählten Software, Koha, untersucht und abschließend zusammengefasst. Im Ergebnis wird festgestellt, dass Koha potenziell das jetzige Bibliothekssystem ablösen kann. Individuelle Defizite der Software, die festzustellen sind, können durch alternative Lösungen einfach und unkompliziert behoben werden. Eine Marktsichtung anderer Systeme sowie eine Kostenanalyse, Projektplanung und Testinstallation bilden keinen Bestandteil dieser Bachelorarbeit.:1. Einleitung 2.

It may seem controversial that open-source software (OSS), i.e. software created by voluntary contributions that is available to use, change, and distribute for free, can be utilized for business purposes. Yet, for some firms, commercial OSS software products are the primary source of revenue. In this thesis, these companies are referred to as OSS vendors. Although some OSS vendors have existed for more than thirty years, how they conduct their business has not been extensively studied. Business models as a concept has been widely used in the information and communications technology (ICT) industry, often when describing firms working with OSS. In that context business models often refer to the offering, i.e. the products the firm offers to its customers and how revenues are collected. However, in academia the business model concept has evolved in a broader sense encompassing several fields and into a rich theoretical field itself. This thesis aims to further the understanding on how OSS vendors conduct their business, by using a business model framework, which has been constructed from business model and management theories. This framework was used to study OSS vendors to investigate the configurations of their business models. A cross-case analysis of four carefully selected OSS vendors searched for generic patterns in these configurations. Furthermore, the cases were also studied regarding sustainability and profitability. Two generic business model configurations were found, community immersion and community utilization. OSS vendors found configured according to the community immersion business model are deeply involved with, but also dependent on, the main community project that provides the software for the offering. OSS vendors found configured according to the community utilization business model are not dependent on the OSS project to provide their commercial offerings. Rather, the communities are used in marketing providing brand benefits, a base for recruitment, and in lesser degree functioned as quality assurance. Two of the four studied companies were found to be profitable and sustainable; one operating according to the community immersion business model and the other according to the community utilization business model. The other two companies studied, observed to operate according to the community utilization business model, did not achieve profitability during the time of the study. The findings should further the understanding of how profitable OSS vendors’ business models could be configured, and thus provide practitioners with an understanding on how different business model configurations can affect their strategies and overall business.

There has been little understanding of how the existence and exercise of formal intellectual property rights (IPR) such as patents influence the direction of OSS innovation. This dissertation seeks to bridge this gap in prior literature by focusing on two closely related topics. First, it investigates how OSS adoption and production are influenced by IPR enforcement exercised by proprietary incumbents. It suggests that when an IPR enforcement action is filed, user interest and developer activity will be negatively affected in two types of related OSS projects--those that display technology overlap with the litigated OSS and business projects that are specific to a focal litigated platform. The empirical analyses based on data from SourceForge.net strongly support the hypotheses. Second, it examines the impact of royalty-free patent pools contributed by OSS-friendly incumbents on OSS product entry by start-up firms. It argues that increases in the size of the OSS patent pool related to a software segment will facilitate OSS entry by start-up firms into the same segment; further, the marginal effect of the pool on OSS entry will be especially large in software segments where the cumulativeness of innovation is high or where patent ownership in a segment is concentrated. These hypotheses are empirically tested through examining the impacts of a major OSS patent pool--the Patent Commons, established by IBM and a few others in 2005--on OSS entry by 2,054 start-up firms from 1999 to 2009. The empirical results largely support these hypotheses and are robust to adding a variety of controls as well as to GMM instrumental variables estimation.
