This work offers a highly useful, well developed reference on Markov processes, the universal model for random processes and evolutions. The wide range of applications, in exact sciences as well as in other areas like social studies, require a volume that offers a refresher on fundamentals before conveying the Markov processes and examples for applications. This work does just that, and with the necessary mathematical rigor.

In order to be considered in the calculation of punching force of cold die random distribution of material properties, meanwhile including success and failure punching during the gradual change process in the calculation. Based on probabilistic fuzzy reliability point of view, the success or failure determination will be extended to fuzzy events. Based on fuzzy reliability, the punching force of cold die calculation method will be also given when taking the impact of random distribution of material properties into account. Related analysis formulae and the fuzzy criterion of success or failure of punching are established and derived. Through which, design and engineering process are integrated, the designer will be more reliably to predict the success or failure of the punching during the design stage. The processing error of lack of statistical data and the objectivity of the success or failure determination criterion will be easily solved. Economy cost and reliability design of geometrical curve design will be also considered.

We present a novel multi-resolution point sample rendering algorithm for keyframe animations. The algorithm accepts triangle meshes of arbitrary topology as input which are animated by specifying different sets of vertices at keyframe positions. A multi-resolution representation consisting of prefiltered point samples and triangles is built to represent the animated mesh at different levels of detail. We introduce a novel sampling and stratification algorithm to efficiently generate suitable point sample sets,for moving triangle meshes. Experimental results demonstrate that the new data structure can be used to render highly complex keyframe animations like crowd scenes in real-time.

Fluorescent concentrators (see Figure 1) are developed and investigated in solar energy research in order to improve the efficiency and applicability of solar cells. This is achieved by concentrating even diffuse light on cloudy days on small solar cells, using a fluorescent dye enclosed in low-cost acrylic glass. We developed a Monte Carlo simulation model for fluorescent concentrators that makes it possible to test and improve different setups and to gain further insight into the physical processes. As it is a complicated topic, fluorescent light has been investigated very rarely in computer graphics. Recent advances in fast ray tracing give the opportunity to simulate complex physical processes using simple models. Changes of the setup and physical properties can be simulated and evaluated quickly, providing the necessary foundation for automatic optimization.

In this paper, we apply a new combination mode to detect throat polyp auxiliary. The Kernel principal component analysis is employed to extract characteristic value of the voice, and neural network pattern recognition to classify the voice data. This method can help diagnosis of throat polyps. As is known, In the modern clinical application, it is not widespread to use electronic laryngoscope. More cases need cutout, clamp or puncture to do pathological examinations, which is very hurt and it takes a long time to wait for the result that may delay the best treatment time. The results of pattern recognition show a beneficial correct rate of prediction under different number of samples and different random measurement matrices.

The availability of devices that track moving objects has led to an explosive growth in trajectory data. When exploring the resulting large trajectory collections, visual summaries are a useful tool to identify time intervals of interest. A typical approach is to represent the spatial positions of the tracked objects at each time step via a one-dimensional ordering;visualizations of such orderings can then be placed in temporal order along a time line. There are two main criteria to assess the quality of the resulting visual summary: spatial quality - how well does the ordering capture the structure of the data at each time step, and stability - how coherent are the orderings over consecutive time steps or temporal ranges? In this paper we introduce a new Stable Principal Component (SPC) method to compute such orderings, which is explicitly parameterized for stability, allowing a trade-off between the spatial quality and stability. We conduct extensive computational experiments that quantitatively compare the orderings produced by ours and other stable dimensionality-reduction methods to various state-of-the-art approaches using a set of well-established quality metrics that capture spatial quality and stability. We conclude that stable dimensionality reduction outperforms existing methods on stability, without sacrificing spatial quality or efficiency;in particular, our new SPC method does so at a fraction of the computational costs.

An argument may be considered sound ("admissible" or "RSA-compliable" in informal logic) if it is well-formed and fulfills a number of reasonable semantic criteria. When agents exchange arguments, not all incoming arguments are sound. This paper formulates two results. First, it gives lower bounds for the verification rate of incoming arguments, given an estimate of the percentage of incoming sound arguments and a predefined tolerance of error. Second, it prescribes what percentage of incoming arguments must be verified if there is no prescribed error tolerance, but there is a tradeoff between cost of verification and cost of error.

This new edition of the successful multi-disciplinary text Statistical Modelling in GLIM takes into account new developments in both statistical software and statistical modelling. Including three new chapters on mixture and random effects models, it provides a comprehensive treatment of the theory of statistical modelling with generalised linear models with an emphasis on applications to practical problems and an expanded discussion of statistical theory. A wide range of case studies is also provided, using the normal, binomial, Poisson, multinomial, gamma, exponential and Weibull distributions. This book is ideal for graduates and research students in applied statistics and a wide range of quantitative disciplines, including biology, medicine and the social sciences. Professional statisticians at all levels will also find it an invaluable desktop companion.

In this paper, composites with a graded distribution of heterogeneities are considered. The heterogeneities vary in statistically non-uniform fashion since in a finite layer (or region) properties such as local volume fraction vary gradually. In order to study this class of composites, a procedure of analysis which leads to the effective constitutive non-local operator of the medium is proposed. For two-phase composites, an approximation of Hashin-Shtrikman type for this operator has been obtained in real space and this has been developed explicitly in the case of laminates.
