Human stance in quiet mode, relies on feedback from eyes, skin, muscles and the inner ear and the control produced is a combination of strategies which enable a person to stay standing. This thesis presents the simulation and control of a hip actuated robotic model of human standing posture. / The first part of the thesis is devoted to recalling basic elements of the human balance system and to describe the balance strategies it uses to maintain an upright stance. Of the strategies presented, we consider the hip strategy which motivated the formulation of a hip actuated robot. An investigation into the control of nonlinear underactuated robots by linear controllers is done to verify the range and efficiency of the controlled system. / The second part of the thesis includes the investigation of two simplified models of the robot. Results using linear state feedback control are presented. The two models used are compared to clarify the use of one over the other. / We found that for linear controls, the size of the region of convergence decreased underactuated systems of increasing complexity. For our four degrees of freedom robot, the region of convergence is of 2.3 degrees for the actuated joints and of 1 degree for the unactuated joints. Our system is Lyapunov stable when the fully simplified model is assumed.

Yes / Pelvic radiography is used for the identification of hip joint changes, including pathologies such as osteoarthritis. Several studies have recommended that the position for this radiological procedure should be standing, not supine, to reflect the functional appearances of the hip joint. The aim of this review was to evaluate pelvis radiography positioning with respect to the image appearances and information provided for clinical decision-making. Aside from this, potential recommendations to the radiographic technique for an erect pelvis projection will be considered. Method: A literature search was performed using databases/ systems (ScienceDirect, Web of Science, PubMed, and MEDLINE). Only articles written in English were included. Results: Twenty-five articles were identified. Findings from the review describe the effect of repositioning from supine to erect on a series of specific hip measurements. These include pelvic tilt, joint space width, and the acetabular component. Conclusion: Evidence within the literature illustrates that in several studies, there were differences when repositioning from supine to standing for a number of pelvic metrics. Standing positioning is promoted by some authors since this may facilitate the early diagnosis of hip joint pathology and assist in the planning of surgical interventions. Literature is very limited on how to optimally perform erect pelvis radiography, and this should be an area for future research.

The main purpose was describe the issue of shooting success rate at high altitude (1 500 - 3 000m a. s. l.). Shooting success rate of elite racers was evaluated using analysation of results from individual races at high altitude in the period 1990/1991 - 2013/2014. High altitude had no statistical effect (p<0,05) on shooting success rate of women and men biathletes in the comparision with lowland but it had more negative effect to women shooting success rate than men shooting success rate. Ten national level biathletes were tested in three tests in lowland, four tests at high altitude and five tests in lowland after the return from high altitude. The test included rest shooting in the prone and standing positions and load shooting in both positions which took part of three kilometers running. Twelve days training camp at high altitude did not improve shooting success rate, shooting velocity and running time in the determinated heart rate. Rest shooting and shooting in the prone position did not change statistically during the whole testing period. At high altitude critical days were registered in load shooting in standing position (6th day, p<0,05) and average running time (9th day, p<0,05). Rifle manipulation and shooting are automate motions which are not influenced by high altitude. Most...
