In the first months of a technological change, it is possible to identify a certain resistance and even some conflicts that affect the levels of productivity of the teams. The objective of this work was to understand the relation of productivity with the changes in the work characteristics of teams that begin to adopt the SCRUM agile method for software development and to propose practices that help to reduce the learning curve and to improve productivity. Through the understanding of the Tuckman model, which describes the five stages of a team development: formation, confusion / conflicts, normalization, performance, and disintegration, a case study was carried out with a team that started to adopt SCRUM and identified the relationship between productivity and the phases described by Tuckman. In this sense, a field research was necessary to find practices that could help teams to increase their productivity during the confusion phase described by Tuckman. Through the preparation of a preliminary proposal, and an it?s preliminary evaluation in a Focus Group activity, this research presents a proposal to use the OKR technique (Objectives and Key-Results) along with SCRUM with the objective of assisting software team development, to concentration in the phase of confusion / conflicts. / Projetos de implanta??o de novas tecnologias devem compreender o impacto imediato que esta mudan?a causa nos profissionais envolvidos em rela??o ao processo de trabalho. Nos primeiros meses de uma mudan?a tecnol?gica ? poss?vel identificar uma certa resist?ncia e at? alguns conflitos que afetam os n?veis de produtividade das equipes. O objetivo do trabalho foi compreender a rela??o da produtividade com as mudan?as nas caracter?sticas de trabalho de equipes que passam a adotar o m?todo ?gil SCRUM para desenvolvimento de software e propor t?cnicas que auxiliem na redu??o da curva de aprendizado e melhora da produtividade. Atrav?s da compreens?o do modelo de Tuckman, que descreve que no desenvolvimento de equipes existem cinco est?gios: forma??o, confus?o/conflitos, normatiza??o, desempenho, e desintegra??o, foi realizado um estudo de caso com uma equipe que passou a adotar SCRUM e identificou-se a rela??o entre a produtividade e as fases descritas por Tuckman. Neste sentido, se fez necess?rio um estudo de campo para encontrar t?cnicas que pudessem auxiliar as equipes a aumentarem sua produtividade na fase de confus?o, descrita por Tuckman. Atrav?s da elabora??o de uma proposta preliminar e sua avalia??o preliminar atrav?s de um Focus Group, essa pesquisa apresenta uma proposta de um da utiliza??o da t?cnica de OKR (Objectives and Key-Results) juntamente com SCRUM com objetivo de auxiliar o desenvolvimento das equipes de desenvolvimento de software, sob a ?tica da produtividade e com foco na fase de confus?o/conflitos.

The aim of the thesis The Middle Bronze Age tumulus culture in north-western Bohemia is to contribute to a deeper understanding of the Middle Bronze Age, and generally to expand our knowledge about this field of prehistoric history of north-western region. The work is divided into three main parts. The first one deals with the analysis of settlement of the tumulus culture in Dobroměřice. The analysis focuses mainly on the findings of the various movable objects, pursuant to which the settlement is situated chronologically. Second, we focused attention on the Middle Bronze Age tombs. He created a list of 51 currently known tomb files. By far the largest space was devoted to typological-chronological analysis of the find of the Fund, both in bronze and ceramic artefacts and the findings of other materials. Based on this analysis has succeeded individual graves units classified chronologically. The theme of the final chapter is the evaluation of sites by the accumulation of all known sites of the Middle Bronze Age in the study area. With made-geographical analysis of settlement can be considered on an overall The Middle Bronze settlement in the region.

The thesis deals with integral and distributed optical fiber sensors of electric current. In the area of integral sensors the analysis is performed by Jones matrix calculus and the simultaneous influence of induced circular and undesired linear birefringence using an ortho-conjugation retroreflector. Furthermore, the proposed conjugation loop variant using half-wave phase retarders is analyzed. The theoretical conclusions are confirmed by simulation and experimental measurement. In the field of distributed fiber optic sensors, analysis and simulation for the detection of plasma currents in thermonuclear fusion reactors, based on the POTDR technique, is performed. An improvement procedure is proposed for circular-shaped vacuum vessel reactors. Plasma current detection procedure in divertor-type reactors have been newly designed and simulated to investigate the effect of the OTDR detector noise on plasma current detection accuracy.
