SPECIFYING A PCMCIA IRIG-106 (Ch. 4) DECOMMUTATORMc Girr, Niall 10 1900 (has links)
International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / There are many applications where an ultra-compact PC (palm-top) is required for quick
analysis of PCM data. There are many design issues associated with the design of a PC-Card
(PCMCIA) decommutator.
• Is it possible to connect a 20Mbps PCM stream?
• What outputs are required from such a card?
• How many cards can be used?
• Which mode to use (memory or I/O)
• How to program such a card
• How to develop third-party software for analysis of data
This paper discusses some of these issues and the applications for such a card.

The Computational Problem of Motor ControlPoggio, Tomaso, Rosser, B.L. 01 May 1983 (has links)
We review some computational aspects of motor control. The problem of trajectory control is phrased in terms of an efficient representation of the operator connecting joint angles to joint torques. Efficient look-up table solutions of the inverse dynamics are related to some results on the decomposition of function of many variables. In a biological perspective, we emphasize the importance of the constraints coming from the properties of the biological hardware for determining the solution to the inverse dynamic problem.

"They're All Sort of Fake, Not Real": An Exploratory Study of Who Young Girls Look Up ToWright, Carole Ann January 2008 (has links)
The purpose of this qualitative study was to explore the phenomenon of role models for younger girls. Girls aged 5 to 12 years were asked who they chose to look up to, how significant their role models were to them, why they had chosen them and if they thought they thought that they could achieve their chosen model‟s achievements. Socio-cultural framework provides a useful perspective for understanding the significance of role models as they act as powerful transmitters and reinforcers of the tenets of socialization. In Social Cognitive Theory, it is claimed that children largely learn through modelling, observing and imitating significant others. Interview and task sessions including a field-mapping activity and the sorting of peer-generated photographs were conducted with 12 girls aged from 5 to 12 years from one urban school. In analysis of the interview data, it was found that family members or family substitutes were the most significant people that these girls chose and, despite the alleged pressure from popular culture, young girls in this study were able to make discerning judgements about the „hollowness‟ of characters of popular culture. They identified skills or attributes that their role models demonstrated rather than physical attractiveness, their popularity or the amount of money their fame had brought them. This study is a valid representation of what mattered to a group of young girls at one specific point in time and could indicate the value of further investigation of how to maximize the benefits of role models for young girls.

Bodies of Light: Affect and the Filmic Gaze in Horacio Quiroga's Cinema StoriesStewart, Morgan Keith 01 June 2017 (has links)
Though Horacio Quiroga is better known for his jungle tales, he was also a prolific film critic. Writing in the early days of silent cinema, Quiroga channeled his love for the new art into a series of four short stories about film: "Miss Dorothy Phillips, mi esposa" (1919), "El espectro" (1921), "El puritano" (1926), and "El vampiro" (1927). These stories not only reveal Quiroga's passion for the cinema, but also showcase the power of film to affect the spectator. The theoretical basis of my study comes from the Deleuzian concept of affect, being defined as the invisible force or intensity which exists in bodies and can also be transmitted between bodies that have differing capacities for acting on each other. In the case of the cinema, the film and the spectator are the two bodies that participate in this transmission of intensities. In the first chapter, I discuss how "El puritano" reveals that film's resurrected images can be more powerful than the originals. Then, I analyze "El espectro," which serves as an example of how film's mimetic qualities increase its power to affect spectators and produce in them visceral reactions. Particularly striking in this story is the filmic gaze of an on-screen actor, a gaze which transmits affect to the other characters. In the second chapter, I analyze "Miss Dorothy Phillips, mi esposa," particularly how it theorizes the erotic gaze of filmed actresses. Then I discuss "El vampiro," in which I study the relationship of two men with the filmed image of a beautiful Hollywood actress. In the story, an inventor is able to "move" film in such a way as to create a spectral woman who can interact with others. However, by the end of the story it becomes clear that it is the film—personified by this spectral woman—that holds the true power in this relationship of bodies.

Le modèle du Look-down avec sélection.Bah, Boubacar 28 September 2012 (has links)
L'objectif de la thèse est d'étudier le modèle du look-down avec sélection dans le cas d'une population composée seulement de deux types génétiques, l'un deux bénéficiant d'un avantage sélectif. Dans cette thèse, cette sélection est modélisée par un taux de mort pour les individus non avantagés. Tout d'abord, nous nous intéressons dans le cas d'une population de taille infinie. Nous montrons que le modèle est bien défini. Nous montrons aussi que dans la limite d'une population de taille infinie, la proportion d'individu d'un type donné suit la diffusion de Wright-Fisher avec sélection. Ensuite nous étudions ce modèle dans le cas d'une population de taille finie et fixée. Nous proposons deux méthodes de convergence de ce modèle fini vers la diffusion deWright-Fisher avec sélection. Enfin, une autre approche est considérée. Nous étudions le modèle de look-down dans le cas d'une population de taille infinie en remplaçant le modèle de reproduction dual du coalescent de Kingman par le modèle de reproduction dual du Lambda-coalescent. Nous montrons d'abord que le modèle est bien défini. Ensuite nous montrons que la proportion de l'un des types converge en probabilité, quand la taille N de la population tend vers l'infini, vers un processus qui est solution d'une équation différentielle stochastique dirigée par processus ponctuel de Poisson. Pour finir, nous montrons que si Lambda-coalescent descend de l'infini alors l'un des types se fixe en temps fini. / The purpose of the dissertation is to study the look-down model with selection in the case of a population composed only two alleles, one of them has a selective advantage. In this thesis, this selective advantage is modelled by a death rate for the wild-type allele. In the first part, we are interested in the case of a population of infinite size. We show the model is well defined. We show convergence in probability, as the population size tends to infinity, towards the Wright-Fisher diffusion with selection. In the second part we study a variant of the simplest look-down with selection where the size of the population is finite and fixed. We propose two methods of convergence of this finite model towards the Wright-Fisher diffusion with selection. Finally, another approach is considered. We study the look-down model with selection when we replace the usual reproduction model, which is dual to Kingman's coalescent by a population model dual to the Lambda-coalescent in the case of a population of infinite size. We first show this model is well defined. We show that the proportion of one of the two types converges in probability, as the population size N tends to infinity, towards the solution of a stochastic differential equation driven by a Poisson point process. Finally, we show that one of the two types fixate in finite time if and only if the Lambda-coalescent comes down from infinity.

Adaptive cruise control utilizing Look-Ahead infromationRost, Johanna January 2009 (has links)
In this master thesis the possibilities of combining an adaptive cruise control with information about the road ahead has been studied. The focus has been to investigate the possibility to save fuel by using information about road topology, Look-Ahead. An adaptive cruise control, AiCC, is used when there are preceding vehicles and when the driver in addition to choosing a desired travel speed for the vehicle also chooses a desired time gap that is to be kept to preceding vehicles travelling slower than the own vehicle. Using information about the road ahead and information of preceding vehicles a controller with the function to adapt the speed to the preceding vehicle, target, and at the same time reduce the fuel usage has been constructed. The controller considers the topography on the road and the distance to the target to be able to reduce the utilization of the brakes in steep downhills and to reduce fuel by slowing down before the downhill and then gain speed due to the gravitational force. The controller uses the assumption that the target travels with constant velocity at all time. The work has included simulations with two different test roads, one in Sweden with shorter and not so steep downhills. The other road is placed in Germany and has long and steep downhills. In the simulations three various time gaps, 1, 2 and 3 seconds, has been used and three different weights of the preceding vehicle, 20, 40 and 50 tonnes. The vehicle with the controller using adaptive cruise control and Look-Ahead has a weight of 40 tonnes. The results shows that fuel can be saved, using information about the road ahead in combination with an adaptive cruise control. The best result is obtained when the road contains steep and long downills, where the vehicle will gain speed due to the gravitational force. For the long and steep downhills the result is best when the target weight is 40 and 50 tonnes. When the downhills are smaller and not so steep the best result is obtained when the target weight is 20 tonnes. For these downhills the assumption that the target travels at constant speed makes the vehicle reduce the speed too much before the downhill, not considering that a heavier vehicle will accelerate in the downhill as well. The time gaps that gives the best result is time gap 1 second. This is due to that the aerodynamic force acting upon the vehicle is reduced when there is a preceding vehicle at a not too far distance. The smaller the distance to the preceding vehicle the more the aerodynamic force is reduced.

Data Requirements for a Look-Ahead SystemHolma, Erik January 2007 (has links)
Look ahead cruise control deals with the concept of using recorded topographic road data combined with a GPS to control vehicle speed. The purpose of this is to save fuel without a change in travel time for a given road. This thesis explores the sensitivity of different disturbances for look ahead systems. Two different systems are investigated, one using a simple precalculated speed trajectory without feedback and the second based upon a model predictive control scheme with dynamic programming as optimizing algorithm. Defect input data like bad positioning, disturbed angle data, faults in mass estimation and wrong wheel radius are discussed in this thesis. Also some investigations of errors in the environmental model for the systems are done. Simulations over real road profiles with two different types of quantization of the road slope data are done. Results from quantization of the angle data in the system are important since quantization will be unavoidable in an implementation of a topographic road map. The results from the simulations shows that disturbance of the fictive road profiles used results in quite large deviations from the optimal case. For the recorded real road sections however the differences are close to zero. Finally conclusions of how large deviations from real world data a look ahead system can tolerate are drawn.
