Teoria quântica da computação

This undergraduate thesis aims formally define aspects of Quantum Turing Machine using as a basis quantum finite automata. We introduce the basic concepts of quantum mechanics and quantum computing through principles such as superposition, entanglement of quantum states, quantum bits and algorithms. We demonstrate the Bell's teleportation theorem, enunciated in the form of Deutsch-Jozsa definition for quantum algorithms. The way as the overall text were written omits formal aspects of quantum mechanics, encouraging computer scientists to understand the framework of quantum computation. We conclude our thesis by listing the Quantum Turing Machine's main limitations regarding the well-known Classical Turing Machines

Construção Enxuta e a utilização dos seus conceitos por construtoras paulistas certificadas segundo o PBQP-H e o QUALIHAB

The civil construction sector has been stimulated to industrialize itself by the adoption of Lean Construction practices in its constructive process. Given this fact, this research verify and identify Lean Tools and the level of application of these Tools in construction companies in the State of São Paulo, in order to be able to notice which Lean Concepts generate the highest benefits to these companies. The research method used was a survey applied only between construction companies that have some type of quality certificate. From the results, a data analysis was made in order to note the constructor's situation in relation to Lean Construction and, based on this analysis, verify the impact of the Lean Principles on the competitiveness of these companies and on the business performance. This way, it was possible to note a high level of application the Lean Tools by the responding companies. It also became clear, by means of this work: the strong influence of the concepts of Flow, of Continuous Improvement and of methods of prevention and resolutions of problems on the overall companies performance
