Die Arbeit umfaßt erstens einen Literaturüberblick über die charakteristischen Merkmale und Besonderheiten des verrukösen Karzinoms (VK) und die Prognose bei unterschiedlichen therapeutischen Herangehensweisen. Von besonderem Interesse ist die LK-Metastasierung von VK. In der Literaturauswertung konnten dabei 18 Fälle ermittelt werden; dabei waren nur in einem Fall Fernmetastasen vorhanden. Die Prognose von VK ist gut bei einer adäquaten chirurgischen Therapie; die Mitbehandlung des Lymphabstromgebietes sollte nicht routinemäßig erfolgen. Zweiter Schwerpunkt der Arbeit ist eine Auswertung des Patientengutes der Klinik und Poliklinik für Mund-, Kiefer- und Gesichtschirurgie der Charité (24 Patienten) und der Hals-Nasen-Ohrenklinik der Charité (13 Patienten) unter der besonderen Fragestellung des Metastasierungsverhaltens und der Prognose von VK. In 2 Fällen wurden LK-Metastasen eines VK festgestellt. In keinem Fall ist das VK als Todesursache eines Patienten bekannt. Bei 8 Patienten traten Rezidive auf. Es wurde festgestellt, daß größere Tumoren schneller und häufiger rezidivieren. Bei der Hälfte der Patienten trat das Rezidiv 4 bis 9 Monate post operationem auf. Die Früherkennung von VK ist wichtig, denn die Prognose ist umso besser, je kleiner der Tumor ist. / The paper comprises first an assessment of literature about the characteristics, and the particularities of verrucous carcinoma (VC), and prognosis dependent on the different therapies. Of particular interest is the lymph node metastatic invasion of VC. The assessment of literature showed in 18 cases lymph node metastases; one VC of these had distant metastases. The prognosis of VC is excellent with adequate surgical therapy. Lymph node treatment should not be routine. Second point of the paper is the assessment of data of 24 patients with VC of the Clinic for Oral and Maxillo-Facial surgery of the Charité and 13 patients with VC of the Clinic for Otorhinolaryngology of the Charité with special attention on metastatic invasion and prognosis of VC. Two patients had lymph node metastases caused by a VC. In no case VC is known as cause of death. Eight patients had relapses. Half of these patients had relapse 4 to 9 monthes post operationem. It was established that larger tumors relapse more often and faster. Early detection of VC is necessary, because the prognosis is the better the smaller the tumor is.

O principal propósito deste trabalho é desenvolver e caracterizar o veículo robótico ℏelvis III, para ser usado no desenvolvimento de pesquisas na área de controle e navegação de robôs móveis. O sistema de propulsão foi caracterizado para determinar a velocidade real do veículo em quatro tipos diferentes de terrenos (Asfalto, grama, grama-terra e terra). Também foi caracterizado o sistema de esterçamento mediante o modelo cinemático da bicicleta, onde se obteve a relação entre a posição do servo motor encarregado do esterçamento do veículo e o valor do ângulo de esterçamento de uma bicicleta. Foram determinados os valores dos erros CEP (Circular Error Probability) e SEP (Spherical Error Probability) do GPS (Global Positioning System) embarcado no veículo mediante dois testes: um em São Carlos – SP (Brasil) e outro em Villavicencio – Meta (Colômbia). Nesses testes foi caracterizada a IMU (Inertial Measurement Unit) embarcada no veículo, além de verificado o efeito da luz solar no funcionamento do sensor tipo LIDAR (Laser Imaging Detection and Ranging) embarcado no helvis III. Por último, pode-se definir a dinâmica do veículo à frente, com a determinação seu centro de massa, e é apresentado o comportamento das forças sob as rodas quando o veículo fica parado ou em movimento sobre terrenos que geram uma inclinação em algum dos eixos cartesianos. / The main objective of this work is the development and characterization of a robotic vehicle ℏelvis III in order to use it in the development of researches focused on the fields of mobile robotics control and navigation. Initially the propulsion system was characterized in order to determine the real velocity of vehicle in real conditions (four different kinds of grounds were used). In addition to this, the steering system was also characterized by applying the well-known bicycle kinematic model. During these experimental tests we could find the relation between the position of the servo-motor and the value of steering angle of the bicycle model. The real values of CEP (Circular Error Probability) and SEP (Spherical Error Probability) errors of the vehicle embedded GPS (Global Positioning System) were determined based on two experiments: the first one was carried out in São Carlos – SP (Brazil) and the second one in Villavicencio – Meta (Colombia). During the GPS experiments we could also characterize the vehicle embedded IMU (Inertial Measurement Unit). Then we could observe and measure the effect of solar light on the LIDAR sensor (Laser Imaging Detection and Ranging) performance. Finally, the forward vehicle dynamics is described, with the determination of the center of mass of the vehicle and the observation of the normal forces behavior in the vehicle wheels when it is stopped or moved on an inclined floor.

Individuals, who work in high risk confrontational (HRC) settings in which a conflict exists, experience high-stress levels in their jobs and are known to have a high level of decreased performance and decreased survival. Individuals being trained to handle such conflicts should be trained effectively to accomplish the ultimate objective, staying alive. The problem is the lack of research and program evaluations examining effectiveness of training simulations in the transfer of skills under HRC settings. The purpose of my study was to test if the skill of target acquisition could be effectively transferred to a real environment (RE) after exposure within a virtual environment (VE). Ackerman's (1988) Theory of Ability Determinants of Skill Acquisition supports the progression participants advance through in the transfer of learning. A randomized posttest only comparison group design was used. The population involved 24 novice paintball players. Participants were randomly assigned to a simulation treatment or a non-simulation comparison application. Two days after receiving the intervention, participants engaged in live practice sessions (game 1 and game 2) in a RE where target acquisition skills were measured. Evidence suggests significant differences were found between novice players in the type of intervention received and the number of targets acquired in a RE, whereas, no significant change in scores was found between practice sessions, and no interaction was found between intervention received and practice. Recommendations for replicating studies include: (a) focusing on the manipulation of specific variables within the training context, (b) using different live environments, (c) examining factors that influence teaming and strategy formation, and (d) combining experts and novice players for a closer representation of a population in an HRC setting.

Este trabalho apresenta três sistemas de controle distintos para a atuação em sistemas de tração elétrica traseira em veículos de passeio convencionais convertidos em VEHs (Veículos Elétricos Híbridos) 4x4, enfocando o desenvolvimento de um sistema diferencial eletrônico (SDE). As principais arquiteturas de veículos híbridos são apresentadas. O SDE, que atua em tempo de execução nas velocidades angulares dos pneumáticos traseiros em manobras variadas, depende dos sinais de esterçamento e aceleração impostos pelo condutor, considerando as modelagens cinemática e dinâmica do veiculo no cálculo dos valores de referência para o controlador. Controladores PID modificado, neurofuzzy baseado em inteligência artificial e um H-Infinito ótimo são projetados e detalhados. Uma nova arquitetura para o SDE é proposta e apresentada, visando a utilização de sistemas de controle robustos no problema do SDE, traçando-se um paralelo entre o seu desempenho e das arquiteturas convencionais quando o controlador H-Infinito ótimo assume o controle do SDE. O projeto e o desenvolvimento de um mini-VEH, a plataforma HELVIS (Hybrid ELectric Vehicle In low Scale), são apresentados. A implementação de um simulador veicular denominado HELVIS-SIM, inspirado na plataforma HELVIS, é também apresentada. O SDE, que compreende a arquitetura proposta e os controladores, são embarcados e também implementados no HELVIS-SIM. Resultados simulados obtidos no HELVIS-SIM são analisados. Testes experimentais do SDE na plataforma HELVIS são apresentados, considerando apenas testes de bancada sem o contato dos pneumáticos com o solo. / This work presents the development of three distinct control systems to rear electric traction control on conventional touring vehicles converted on 4WD (four-wheel drive) hybrid electric vehicles (HEVs), focusing on the design of a EDS (Electronic Differential System). Main HEV architectures are presented. The EDS controls the rear wheels angular speeds as the driver inputs steering and acceleration commands, considering both dynamic and kinematic models of the vehicle and so the actuators on the calculus of the desired rear angular speeds. One modied PID controller, one AI (Articial Intelligence) based controller and one robust optimal H \'infinite\' controller are designed and outlined. A new EDS architecture is proposed and presented, aimming the use of robust controllers to the EDS problem, comparing the use of the H \'infinite\' optimal controller to conventional EDS architectures. The design of a mini-HEV, the HELVIS (Hybrid ELectric Vehicle In low Scale) platform is also presented. The implementation of a parametric vehicular simulator, the HELVIS-SIM, is discussed. The EDS, which represents the controllers and the proposed architecture, is evaluated on the HELVIS platform and on the HELVIS-SIM. Simulated results are rst run in the HELVIS-SIM. Experimental results of the EDS tests are presented exclusively considering the evaluation on a bench test, without any contact of the platform with the pavement.

The structure that develops finds support in the work "The New Separation of Powers" Bruce Ackerman, which develops a framework of separation of powers called 'limited parliamentarism'. The model presented in this work is the breakdown of the classical structure of the tripartite powers, inspired by Montesquieu, and opening for numerous other instances of control, beyond redistribution of existing functions. The work presents a proposal to amend the Federal Constitution to insert the new model of separation of powers. Finally, we analyze the validation of this new model in Brazil, through a constitutional amendment. The goal that we seek with this new model is the democratic legitimacy as an exercise in democracy, the efficiency of state action and the protection and expansion of Fundamental Rights. / Este presente estudo propõe uma nova estrutura da separação dos poderes no Brasil.

O trabalho apresenta uma proposta de alteração da Constituição Federal para inserção do novo modelo de separação dos poderes. E, por fim, analisa-se a validação deste novo modelo no Brasil, por meio de emenda constitucional. O objetivo que se busca com esse novo modelo é a legitimidade democrática como exercício de democracia, a eficiência da atuação do Estado e a proteção e a ampliação dos Direitos Fundamentais.
