Dramatic increasing of amount of data in running a business has been consireded a typical phenomenon of the last decade. This fact, however, has its impact on the business planning and decision making. The area, which deals with this problematics, is called Business Intelligence (BI). The problem lies in the implementation of applications directing to the BI, because it is often oriented only on isolated projects, so they cause only partial effect. In such cases, BI cannot fulfil the expected role, but still preserves the negatives instead. By saying negatives, it is meant: complicated searching for analytical outputs, significant dete-rioration of their output data, cost increase in administation of BI systems, and others. The solution can represented by integration of partial BI systems and by transfer of their BI metadata into a single informational system, serving as an "entering gate" for all the business workers. From the whole company perspective, there exist also benefits in the metadata managament, such as: determination of quality and usage of reports, prolonging of the life cycle, cooperative forming of the knowledge basis, consolidation of the terms in the business, more efficient way of browsing in the system and comprehensibility of analytical system's outputs. The aim of this diploma thesis is formation of a metadata presentation and its realization into a preselected information system, together with meeting of the advantages resulting from applying business metadata.

There are two different types of platforms in the world of business intelligence - commercial and open source. The main objective of this thesis is to compare two representatives of both worlds - IBM Cognos BI version 10 and Pentaho BI Suite 4.1. This thesis is focused on the theoretical comparison of platforms according to defined benchmarks. Practical application of both platforms is described on example of model company MATASTAV. In the introduction the main topic, objectives and benefits are defined. Then it is necessary to describe expressions that may occur on following pages. The initial situation is defined by example of company MATASTAV. Both platforms are introduced in the next part and then are defined benchmarks with selected method of comparison. Platforms are theoretically and practically compared on following parts of this thesis. Conclusion contains results from both comparisons. Major benefit of this thesis is based on the practical comparison of both platforms on the example company MATASTAV and gathering of personal experiences and problems solved.

In order to solve a highly indeterminate rigid frame structure by the method of slope deflection a high order stiffness matrix needs to be inverted. Existing computer programs for the IBM Type 650 Computer are entirely too time consuming when the matrix coefficients and program instructions exceed the storage capacity of the computer drum. The method described in this paper involves the solution of the problem by the inversion of a partitioned matrix originally described by Duncan, Prazer, and Collar. Machine time was reduced by 91% using the new method. The program retains accuracy of six significant figures for a matrix normally twice as large as a machine can handle at one time, and four plus significant figures if the matrix is four times as large as the computer can handle in one storage operation. The method can be applied to digital computers of any size, thus increasing their apparent storage capacity or decreasing their operating time for a matrix inversion. The method is applicable to symmetrical as well as unsymmetrical matrices. / Master of Science

Le langage algorithmique Algol définitivement codifié en 1960 , a été l'objet, dès l'année 1961, de nombreuses tentatives d'analyse syntaxique ayant pour but sa traduction (ou compilation) dans des langages directement interprétables par les calculateurs arithmétiques modernes. L'Université de Grenoble, en particuliers, réunit au mois d'octobre 1961, sous la présidence de M. Kuntzmann, Directeur de l'Institut de Mathématiques Appliquées de Grenoble, un groupe de chercheurs destinés à réaliser la compilation d'Algol60 sur les machines les courantes en France.<br />Le groupe Algol s'est réuni régulièrement jusqu'au mois de janvier 1962, date à laquelle il se scinda en trois sous-groupes orientés chacun sur une machine déterminée.<br />Le travail que nous présentons ici a été élaboré à l'intérieur de celui de ces sous-groupes orienté sur les machines I.B.M. 7090/94 puis 7040/44/

O esquema de decaimento beta do 100.ANTPOT Rh foi estudado a partir de medidas de espectroscopia gama simples e coincidência gama-gama. Foram observadas e atribuídas ao decaimento beta do 100.ANTPOT Rh 132 transições gama, das quais 68 pela primeira vez. Um número de 32 estados excitados do 100.ANTPOT Rh foram observados sendo que os de energia 2512 keV, 2536 keV, 2543 keV, 2569 keV, 2666 keV, 2745 keV, 2774 keV, 2801 keV e 3072 keV pela primeira vez a partir do decaimento do 100.ANTPOT Rh. Os valores de spin e paridade de vários estados foram propostos com base nas transições observadas nos valores de log(ft) obtidos e nas informações de trabalho anteriores. A meia-vida do decaimento do 100.ANTPOT Rh também foi medida e o valor obtido foi de 20,2(1) h. Um tratamento estatístico levando em conta a covariância foi utilizado no cálculo das energias das transições gama e dos níveis, das intensidades de transição gama e de alimentação beta. Os estados excitados experimentais para o 100.ANTPOT Rh foram comparados com os obtidos do modelo de bósons interatuantes. Observou-se que este modelo, no limite algébrico SU(5) (correspondendo a um vibrador do modelo geométrico) com a inclusão da interação de 3 bósons (relacionada com deformação triaxial), produz um esquema de níveis bastante compatível com o esquema experimental. / The beta decay scheme of 100.ANTPOT Rh has been studied through simple gamma spectroscopy and gamma-gamma spectroscopy. With these two measurements, 132 gamma transitions have been observed and scribed to the 100.ANTPOT Rh decay, 68 of them for the first time. A number of 32 excited states of 100.ANTPOT Rh have been observed and some of them for the first time in the beta decay of 100.ANTPOT Rh (2512 keV, 2536 keV, 2543 keV, 2569 keV, 2666 keV, 2745 keV, 2774 keV, 2801 keV, and 3072 keV). A 20.2h half lofe for the beta decay of 100.ANTPOT Rh has been measured and spin and parity values for several states have been proposed, taking into account the observed transitions, the calculated log(ft) values and the beta intensities. A covariant statistical treatment has been used to calculate gamma transitions energies and intensities, level energies and beta feeding intensities. The experimental excited states of 100.ANTPOT Rh have been compared with those obtained from the interacting boson model. The algebraic SU(5) limit of this model (that correspond to an oscillator in the geometrical model), with the inclusion of 3 boson interaction (related with triaxial deformation), produces a level scheme in good agreement with experimental data.
