Guo, Shuibao. „High performance digital controller for high-frequency low-power integrated DC/DC SMPS“. Lyon, INSA, 2009. http://theses.insa-lyon.fr/publication/2009ISAL0033/these.pdf.
Der volle Inhalt der QuelleDespite being a popular research topic, digital control is still seldom applied in practical low-power high-frequency integrated SMPS converters. Phones, PDAs and music/video players are still mainly designed with analog PWM control inside the voltage regulator blocks. This is mainly due to the apparent complexity of implementation, cost constraint and absence of digital controller architectures that can support operation at switching frequencies significantly higher than 1MHz with low-power consumption features. Broader acceptance of digital techniques in low-power high-frequency SMPS is still hampered by practical problems of the combination of cost issues, trade-off performances and power consumption. However, with the rapid development of Very Large-Scale Integration (VLSI) technologies and CMOS manufacturing technique, and associated with their design tools in the last decade, it is now very possible to realize the high performance digital control in power electronics system by high-speed low-power digital devices (FPGA, ASIC, etc). With these advantages, the implementation of digital controller has become more feasible for low-power high-frequency SMPS design in portable electronics applications. The research interest of the thesis is to explore practical ways of incorporating advantages of digital control in practical implementation, investigates issues of digital controller implementation at lower power levels, gives detailed guidelines for digital controller design and hardware selection, and proposes new hardware solutions for the main functional digital controller blocks. Two main objectives of this work focus the implementation of high-resolution high-frequency digital PWM (DPWM) and high-performance digital control algorithms for SMPS in FPGA-based realization

Der volle Inhalt der QuelleA way to improve both electric and hybrid vehicles is to use high speed motors, operating over than 42.000rpm. The goal is to increase the power density and the efficiency of powertrains. Using these new motors, new gearboxes should be developed. This must be done without generating significant additional cost regarding already mastered low speed solutions. High energy performance level also has to be maintained. This PhD comes before the design phase of a high-speed oil bath lubricated gearbox. It aims to identify the warm-up and power loss problems, and propose ways to improve efficiency. This work proposes a thermomechanical modelling of the gearbox’s first stage, using the thermal network method. This model links power losses with temperatures. Particular attention is paid to high speed bearing modelling. A new thermomechanical model of rolling element bearing is developed. As churning losses being significant at high speeds, a method to greatly reduce this power loss is characterized

Der volle Inhalt der QuellePerformance in sprint canoe-kayak has been associated with maximal O2 uptake (VO2max), lactate threshold, as well as anaerobic fitness and muscle qualities. However, the physiological peculiarities of sprint canoe-kayak suggest that the peripheral component of the aerobic system, and more precisely the muscle O2 extraction capacity, is an important determinant of performance. A good understanding of the key performance indicators is crucial to validate training programs and tests used to monitor training adaptations in athletes. With the advent of portable and affordable near infrared spectroscopy devices, it is now possible to measure changes in muscle oxygenation (SmO2) in different active muscles during exercise. Thus, the goals of the four articles included in this thesis were to characterize the changes in muscle oxygenation during exercise and in response to different types of training in order to better understand the role of peripheral adaptations in sprint canoe-kayak performance and explore the effect of different types of training on these physiological parameters and on performance. Study 1, examining the association between muscle oxygenation parameters and 200m, 500m and 1000m performance in provincial to international level canoe-kayak athletes, concludes that maximal O2 extraction in the muscles studied is the best predictor of performance over all three distances, and suggests that O2 extraction is a better predictor of performance than VO2max in sprint canoe-kayak. In Study 2, the evaluation of the acute physiological response to various interval training sessions indicated that sprint interval training (SIT), compared to short interval training (HIIT), induces the lowest SmO2 levels and cumulates the longest time at low SmO2, potentially making it a stimulus of choice to generate muscle O2 extraction adaptations, and therefore improve performance in sprint canoe-kayak. Study 3 assessed changes in muscle oxygenation in response to a 3-week training camp in a group of elite athletes, to assess whether the training usually prescribed to kayakers elicits peripheral adaptations. After the training camp, the improvement in performance over 200m and 1000m was concomitant with reduced SmO2, suggesting an improvement in O2 extraction capacity. Finally, in the last study of this thesis, the effect of a SIT or HIIT program on muscle oxygenation parameters and on performance over 200m, 500m and 1000m was measured, in order to assess whether sessions generating low and sustained levels of SmO2 present an optimal stimulus for improving O2 extraction capacity. HIIT improved performance in all three time trials, while performance improvements were trivial after SIT. VO2max was unchanged after training, but the maximum deoxygenation achieved in the 1000m time trial was increased in response to both training types. In the 1000m, the increase in performance with training was associated with the increase in maximal deoxygenation in the latissimus dorsi and vastus lateralis muscles, especially in the HIIT group. While these results do not support the hypothesis that SIT would be a better stimulus than HIIT to induce peripheral adaptations, they do highlight the important contribution of peripheral adaptations to sprint kayaking performance. Thus, the results presented in this thesis allow for a better understanding of the physiological demand of sprint canoe-kayak and attest to the role of peripheral adaptations, and more specifically of the muscle O2 extraction capacity, as a physiological determinant of performance. They confirm that training is associated with increased O2 extraction capacity, and that the latter is associated with increased performance. Given these results, it becomes clear that the training of sprint canoe-kayak athletes should aim at optimizing peripheral adaptations. Measuring changes in muscle oxygenation during exercise during tests, training sessions and time trials can provide valuable information on the athlete's profile, help identify the physiological components to be optimized and assess the athlete's response to the training program, and would be a valuable tool to add to the monitoring performed with canoe-kayak athletes.

Der volle Inhalt der QuelleThe aim of this work was i) to validate a method to calculate force during bench press exercise according to data obtained with a kinematic device; ii) to relate the muscle characteristics of the upper and lower limbs of throwers (discus, hammer and shot-put) to the performance; and iii) to propose a protocol adapted to throwers’ evaluation. Firstly, forces calculated according to data obtained with a kinematic device during bench press exercise were compared to those simultaneously measured with a force platform. The results showed the importance of taking the upper limbs mass into account when forces are calculated using a kinematic device. Secondly, muscular characteristics of the upper (maximal power, force and velocity determined from bench press exercise) and lower limbs (maximal power, force and velocity determined from half squat exercise and musculotendinous stiffness) were analyzed in a group of high level male throwers. Whatever the throwing events considered, results demonstrated that throwing performance was associated on the one hand with high lower limb strength and a high level of leg stiffness, and on the other hand with a upper limbs maximal power. Finally, force, velocity and power determined during cycling and those obtained from half squat exercise were compared. From a quantitative point of view, power, force and velocity values determined during cycling were significantly different. However, the same relationships between muscular characteristics and throwing performance were evidenced. In line with previous analysis the following testing protocol could be suggested: half-squat 1-RM (one repetition maximal) and musculotendinous stiffness determination for lower limbs, and maximal power estimation from one bench press against a barbell without load for upper limbs

Der volle Inhalt der QuelleThe present thesis fits on the border of muscle physiology and biomechanics. Three studies investigated the factors influencing the relationship between vertical jump (DV) and maximal power out on cycle ergometer (Pmax). Study A, conducted on 106 participants from two groups (volleyball players, VB, and physical education students (PES) without specific training in jumping or cycling exercises) including 67 Caucasian (C) 39 West African (WA) origins, showed significant effects of sports practice (VB>PES) and enthnicity (E) (WA>C) on countermovement jump with arm swing (CMJA). However, the difference in Pmax was not significant between groups. The CMJA-Pmax relationships were different in C and WA (P=0.003). Therefore, CMJA predicted from Pmax would be underestimated in WA. The same difference was observed for CMJA-PmaxArms relationship. Study B, conducted on 84 participants, showed E significant difference (WA>C) in DV on a force platform in squat jump (SJ), countermovement jump (CMJ), CMJA, CMJA-CMJ, CMJA/CMJ. The effect sizes of E were large for CMJA, CMJA-CMJ, CMJA/CMJ and medium for CMJ and SJ. E effect of countermovement jump (CMJ-SJ) was not significant. In study C, the effects of anthropometric factors [body height (BH), sitting height (SH), foot length (FL), leg length (LL), Body Weight (BW), BMI, Body fat (BF), BF/BW and Skelic (Sk=LL/SH) or Cormic (Co=SH/BH) indices], and E (C vs WA) on SJ, CMJ and CMJA)] have been measured on a force platform in 55 PES [32 Caucasians (group C) and 23 West-Africans (group WA)]. Only SH, Sk and Co were significantly different in C and WA. All DV performances were higher WA The ethnic difference in SH could partly explain the higher DV values in WA

Der volle Inhalt der QuelleHigh-intensity interval training (IT) is superior to continuous training for improving endurance performance. Inframaximal IT (performed at intensities below maximal aerobic power [MAP]) is widely used by endurance athletes, but supramaximal IT (performed at intensities above MAP) is also associated with improved endurance performance. By now, it is unkown which type of IT leads to the best performance outcomes. The purpose of this study was to assess the effects of supramaximal and inframaximal IT on key endurance performance determinants. After six weeks of training, despite a 47 % lower training volume, supramaximal IT led to an increase in maximal oxygen consumption (VO2max) similar to inframaximal IT. MAP was increased following inframaximal IT only, and only supramaximal IT increased anaerobic capacity.
Mendes, Andréa Cristina. „Choréopolitique d'un devenir hybride : l'art de la performance comme puissance critique dans la traduction du déséquilibre“. Thesis, Paris 1, 2015. http://www.theses.fr/2015PA010562.
Der volle Inhalt der QuelleThe following thesis is a research about the art of performance in its aesthetic, political,ethical, cognitive and subjective implications; within the Brazilian anthropophagy tradition’s artistic and cultural context in the period when the art of performance emerges as an artistic genre, in the sixties and seventies. Faced with such implications, the art of performance not only indicates a process of hybridization of artistic genres and the relations between artist, work and spectator; but also indicates a whole different way of existence: « becoming-hybrid ». Defining « hybrid » as an intruder paradigm who overcomes the age of signification, one that assumes a hegemonic and uncritical trend in the world established by Western modernity; we ask ourselves about the critical contributions and challenges of becoming-hybrid in the art of performance and in the culture, especially considering the mechanisms that blocks the new ways of feeling and of production of subjectivity.To develop this discourse, we lean foremost on the concept of: the esthetic ideas of Deleuze-Guattari; the psychodynamic approach to subjectivity and the sensitive ways to deal with the otherness of thought of Suely Rolnik; the reformulation of the anthropophagic tradition according to the Anthropophagous manifesto by Oswald de Andrade; the theory of perspectivism; and the Amerindian myth by the anthropologist Viveiros de Castro. In this sense, in order to increase the critical power of the body and other ways of existence concerning the hybridization of the world, we propose the thinking of performing art as a hybrid paradigm of some another modernity. The way of creation, the resistance and the knowledge of the performer show a critical attitude and a heterogenetic dynamic, an alter-action of himself and of the world itself, which is very similar to the old anthropological matrix of anthropophagy. The performer, then, affirms the possibility of the emergence of another modernity, possibly linked to another kind of hybrid world, an animistic and completely anti monotheist world, which understands life as devouring, as immanence of the danger and imminence of the meaning. A world where social solidarity is defined by otherness and where the indian cogito would be « it exists, therefore it thinks »
Debraux, Pierre. „Etude des déterminants de la performance en cyclisme: puissance musculaire et aérodynamisme. Application en BMX“. Reims, 2010. http://theses.univ-reims.fr/sciences/2010REIMS013.pdf.
Der volle Inhalt der QuelleThe BMX competitions take place on a specific track of 300-400 m with bumps and turns, and with a downhill start. The displacement velocity reached by the riders may be greater than 70 kmh-1 a few seconds after the start. Few scientific studies focused to the parameters related to the performance in BMX. Nevertheless, a study showed that the starting phase was capital and that the maximum muscle power was a major contributor to performance during this phase. The aim of this thesis is to study the determinants of performance in this sport in focusing on two main parameters: the muscular power output of the lower limbs and a variable of aerodynamics, the projected frontal area. Firstly, the study of the muscular power output in lower body during sprints on a cycle ergometer and a ½ Squat among road cyclists and BMX riders showed that the muscle cross-sectional area and maximal muscle strength were indicators of performance for all-out sprints (~ 6-30s). A comparison of muscular inertial profiles has shown that BMX riders produced a maximal power output with relative light loads and it was necessary to increase muscular power output at heavy loads. Secondly, a new field method for measuring the projetcted frontal area in cycling has been tested. This method is reproducible and valid in comparison to the methods of weighing photographs and digitization. This method was used to measure the projected frontal area of BMX riders during 80 m sprints. These sprints allowed to highlight the importance of the maximal power, the projected frontal area and the average pedaling rate on the chronometric performance and the need to find an optimal gear to decrease the difference between the average pedaling rate and the optimal pedaling rate. To optimize the performance in competition among the BMX riders, it seems necessary: i) to follow a resistance training to increase muscle mass and muscle maximal strength of the lower limbs; ii) to adjust the gear ratio depending on the riders; and iii) to optimize the projected frontal area for some phases of the race. Solutions are proposed in this thesis
