We propose a slight modification of the Berlekamp-Massey Algorithm for obtaining the minimal polynomial of a given linearly
recurrent sequence. Such a modification enables to explain it in a simpler way and to adapt it to lazy evaluation.

This paper describes interactive facilities for simulating abstract muscle actions using Rational Free Form Deformations (RFFD). The particular muscle action is simulated as the displacement of the control points of the control-unit for an RFFD defined on a region of interest. One or several simulated muscle actions constitute a Minimum Perceptible Action (MPA), which is defined as the atomic action unit, similar to Action Unit (AU) of the Facial Action Coding System (FACS), to build an expression. 相似文献

GnRH analogs are used to suppress pituitary-gonadal activity in children with true precocious puberty. The indications for therapy in this situation are not established, as some girls have a slow evolutive form, and the capacity of GnRH analogs to preserve the adult height has not been evaluated. This study analyzes the growth and adult heights of 2 groups of girls with idiopathic true precocious puberty, 1 with a predicted height of 155 cm or less (group 1, 19 cases) and the other with a predicted height of more than 155 cm (group 2, 15 cases). Group 1 patients were treated with a long-acting GnRH analog (D-Trp6-GnRH), and group 2 patients were followed without therapy. Group 1 showed greater clinical signs of estrogenization, vaginal maturation index (P < 0.03), plasma estradiol (P < 0.0004), and ratio of LH/FSH peaks (P < 0.01) at the initial evaluation than did group 2. The mean target heights were similar (difference, 0.9 cm). In group 1, the adult height (159 +/- 1.1 cm) was greater than the predicted height before therapy (152 +/- 1.4 cm; P < 0.0001). The difference between the adult height and the predicted height before therapy (mean, 6.5 cm) correlated positively with the bone age advance (P < 0.01), negatively with the predicted height (P < 0.05), and positively with the difference between the target and predicted heights (P < 0.001) before therapy. In group 2, the adult height (162 +/- 1.4 cm) was similar to the predicted height at the initial evaluation (162.5 +/- 1.4 cm). Adult heights correlated with target height in group 1 and with predicted height at the initial evaluation in group 2. In conclusion, some girls with true precocious puberty and poor adult height prediction who are treated with GnRH analog achieve an adult height more comparable to their target height. However, the lack of effect on height in girls with predicted height at the onset of therapy similar to their target height and preservation of the growth potential in the slow evolutive forms suggest that these forms might not require immediate therapy. Careful follow-up before therapy may be a better way of evaluating their natural course. 相似文献

A new cryogenic instrument was designed for the trapping of aerosols such as cigarette mainstream smoke at low temperature. The technique enabled the trapping of the mainstream smoke of a single cigarette and the particulate and vapor phases were trapped simultaneously. 2R4F reference cigarettes were smoked under International Standard Organization (ISO) regime and trapped at low temperature using the cryogenic instrument. After trapping, the mainstream smoke of the 2R4F reference cigarette was diluted with a solvent and selected smoke components could be quantified using gas-mass spectrometry (GCMS) and high-performance liquid chromatography (HPLC). The capability of the instrument for trapping the mainstream smoke was demonstrated. The feasibility of the procedure for the detection and the quantification of a large range of smoke components including carbonyls, alkaloids and organic volatile compounds (VOC) in the mainstream of a single cigarette was also shown. 相似文献

An experimental method is proposed to characterize the diffusional transfer of adsorbable gaseous solute medium in a porous medium. Three types of experimental measurements are used to successively access to the solute apparent diffusivity in the gas phase, in the adsorbed phase and to check whether the hypothesis of the thermodynamic equilibrium between the gas phase solute and the adsorbed solute is verified during the transient transfer process. This methodology is applied to a longitudinal section of a beech wood sample for the water transfer in the wood hygroscopic domain. 相似文献

Abstract This paper describes the making of a short film on the Xian terra‐cotta soldiers using our integrated HU‐MANOID software. The method of creating and animating the soldiers’ faces is first presented. Then, we show how our approach, based on metaballs and spline surfaces, was used for designing and deforming soldiers’ bodies. For the animation of the bodies, we describe the motion control methods. Clothes for the soldiers are then described as well as horses and decor design. For the rendering, we explained our strategy using parallel machines. Finally, problems of integration are addressed. 相似文献

In this paper we present a new character animation technique in which the animation adapts itself based on the change in the user’s perspective, so that when the user moves and their point of viewing the animation changes, then the character animation adapts itself in response to that change. The resulting animation, generated in real-time, is a blend of key animations provided a priori by the animator. The blending is done with the help of efficient dual-quaternion transformation blending. The user’s point of view is tracked using either computer vision techniques or a simple user-controlled input modality, such as mouse-based input. This tracked point of view is then used to suitably select the blend of animations. We show a way to author and use such animations in both virtual as well as augmented reality scenarios and demonstrate that it significantly heightens the sense of presence for the users when they interact with such self adaptive animations of virtual characters. 相似文献
