A Biomecânica Ocupacional procura aprimorar as condições de trabalho objetivando prevenir e reduzir as lesões, aumentar o desempenho dos operários reduzindo sobrecargas. Pesquisas nesta área indicam que não apenas a manipulação de materiais pesados, mas também posturas pouco naturais e movimentos súbitos e inesperados provocam lesões no sistema osteomuscular que afetam principalmente o pescoço, membros superiores e região lombar. Alguns profissionais apresentam alto risco ao aparecimento desses distúrbios envolvendo principalmente os membros superiores e região lombar, particularmente os digitadores, operadores de caixa de supermercados, dentistas, motoristas profissionais e operadores de trens metropolitanos. Este estudo teve como objetivo estimar a carga mecânica e a atividade muscular no membro superior esquerdo de maquinistas condutores de trens metropolitanos durante o trabalho. Especificamente, o estudo procurou estimar a carga mecânica sobre a articulação do ombro, avaliar a atividade muscular dos músculos tríceps e flexores do punho e verificar a ocorrência de fadiga muscular durante a realização da tarefa, para isto foram investigados o fator de risco relacionado a enfermidades dos membros superiores, o torque sobre a articulação do ombro e a freqüência mediana do sinal eletromiográfico. O método RULA indicou para atividade estudada um escore final quatro, que sugere mais investigações e mudanças podem ser requeridas, pois a postura adotada gera desconforto. O torque calculado sobre a articulação do ombro é aplicado por cerca da metade da jornada de trabalho e apresentou valor médio de -4,1 Nm com o manete na posição 0. A instauração de fadiga sobre os músculos Tríceps Braquial e flexores do punho não foi observada. Estudos futuros são recomendados para desenvolvimento de cabinas de trens metropolitanos com layout ergonômico e posicionamento de instrumentos que possibilite uma postura mais adequada dos operadores / Occupational biomechanics seeks to improve the conditions of work aiming to prevent and to reduce the injuries, to increase the performance of workers reducing overloads. Previous researches in this area indicate that not only handling the of heavy material, inadequate postures and unexpected and sudden movements provoke injuries in the musculoskeletal system that affect mainly the neck, upper limbs and the lumbar region. Some workers present high risk to the develop those disturbances involving mainly the upper limbs and the lumbar region, particularly the keyboarders, supermarket cashiers, dentists, professional drivers and operators metropolitan train. This study aimed to estimate the mechanical load and the muscular activity in the left upper limb of metropolitan train drivers during the work. Specifically, the study sought to estimate the mechanical load on the joint of the shoulder, evaluate the muscular activity of the muscles triceps and flexors of the wrist and verify the occurrence of muscular fatigue during the achievement of the task. For this purpose, it were investigated the risk factor related to the diseases of the upper limbs, the torque on the joint of the shoulder and the median frequency of the electromyographic signal. The method RULA indicated for activity a score final four, which suggests more investigations and changes may be required because the usual posture adopted generates discomfort. The calculated torque on the joint of the shoulder is applied by about half of the day at work and showed the average value of -4.1 Nm with the handle in position 0. The instauration of fatigue on the muscles Tríceps brachial the wrist flexor was not observed. Thus, future studies are recommended to the development of the metropolitan trains\' berths with ergonomic layout and positioning of instruments that enables an adequate posture of its users

We live in an age defined by the automobile and its infrastructure. This paradigm of movement has shaped how we live our lives, and the urban frameworks we inhabit. Cars as a form of transportation damage the environment and engender unsustainable lifestyles. They also create anti-social spaces with the infrastructure they require, and therefore their success is inverse to that of the pedestrian experience. I seek to adapt this transit paradigm with a more flexible and resilient multimodal system. My work focuses on reinvigorating a rail line in central Massachusetts and designing a modular station system that can serve as a new kind of civic architecture. The station grows and shrinks between towns of different sizes, and over time. It slots into existing communities with little disruption, and is programmatically fluid and diverse, such that an array of stakeholders become invested in its success. It also presents as a new type of civic architecture; a building that represents a larger system, while also maintaining its place in local communities.

The digital transformation is increasingly affecting the field of intralogistics. In order to develop corresponding concepts in logistics planning in a short time, software tools should profitably transfer the theoretical knowledge into practice and support the user in the best possible way. This article gives insight in particular into the typical tasks involved in the planning and optimization of internal transport processes and how LOGSOL as a consultany company addresses these with the help of the RoutMan planning tool.:1. Introduction 2. Planning of internal transport processes 3. LOGSOL's approach to planning and optimizing internal transport processes 4. Conclusion

This master thesis deals with the detection and recognition of faces in the image. The content of this thesis is a description of methods that are used for the face detection and recognition. Method described in detail is the principal component analysis (PCA). This method is subsequently used in the implementation of face recognition in video sequence. In conjunction with the implementation work describes the OpenCV library package, which was used for implementation, specifically the C ++ API. Finally described application tests were done on two different video sequences.

The focus of the thesis is to design a modernization of the Bohuslavice nad Vláří train station.
