In this article, we present an overview of methods for sequential simulation from posterior distributions.
These methods are of particular interest in Bayesian filtering for discrete time dynamic models
that are typically nonlinear and non-Gaussian. A general importance sampling framework is developed
that unifies many of the methods which have been proposed over the last few decades in several
different scientific disciplines. Novel extensions to the existing methods are also proposed.We showin
particular how to incorporate local linearisation methods similar to those which have previously been
employed in the deterministic filtering literature these lead to very effective importance distributions.
Furthermore we Describe a method which uses Rao-Blackwellisation in order to take advantage of
the analytic structure present in some important classes of state-space models. In a final section we
develop algorithms for prediction, smoothing and evaluation of the likelihood in dynamic models.
Techniques for storing and processing data are at the heart of all programs. The term data structure is used to Describe the way data is stored, and the term algorithm is used to Describe the way data is processed.

The FiST (File System Translator) system combines two methods to solve the above problems in a novel way: a set of stackable file system templates for each operating system, and a high-level language that can Describe stackable file systems in a cross-platform portable fashion. Using FiST, stackable file systems need only be Described once. FiST s code generation tool, fistgen, compiles a single file system description into loadable kernel modules for several operating systems (currently Solaris, Linux, and FreeBSD). The project demonstrates that with FiST, code size and development time are reduced significantly, while imposing a small performance overhead of only 1-2％. These benefits are achieved, as well as portability, without changing existing operating systems or file system.
From helping to assess the value of new medical treatments to evaluating the
factors that affect our opinions and behaviors, analysts today are finding
myriad uses for categorical data methods. In this book we introduce these
methods and the theory behind them.
Statistical methods for categorical responses were late in gaining the level
of sophistication achieved early in the twentieth century by methods for
continuous responses. Despite influential work around 1900 by the British
statistician Karl Pearson, relatively little development of models for categorical
responses occurred until the 1960s. In this book we Describe the early
fundamental work that still has importance today but place primary emphasis
on more recent modeling approaches. Before outlining
This file contains a selection of VHDL source files which serve to illustrate the diversity and power of the language when used to Describe various types of hardware. The examp

synthesised using current synthesis tools.
This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to Describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.
The code on this diskette has been organized by chapter. Each subdirectory
containing listing has a readme.txt describing program usage and any relevent
file formats. The readme will also Describe how to compile the target
programs under IBM OS/2 (TM) using the using C Set++ compiler (TM). All programs on
this diskette have been compiled and tested in this environment. The majority
of programs on this diskette should port to other environments with only minor
adjustments. The exception to this are those programs which utilize
presentation manager for graphical display of program data. In particular,
the grid1 programs in \chapt4\backprop\ and \chapt3\ fall into this latter category.
C 開(kāi)發(fā)的有限元軟件，界面還可以，不錯(cuò)，可以試試。 FElt is a free system for introductory level finite element analysis. It is
primarily intended as a teaching tool for introductory type courses in finite
elements - probably in the mechanical/structural/civil fields. In a command
line environment, FElt uses an intuitive, straightforward input syntax to
Describe problems. It also includes a graphical user interface for
workstations that allows the user to set-up, solve and post-process the
problem in a single CAD-like environment.
Range imaging offers an inexpensive and accurate means for
digitizing the shape of three-dimensional objects. Because most
objects self occlude, no single range image suffices to Describe the
entire object. We present a method for combining a collection of
range images into a single polygonal mesh that completely Describes
an object to the extent that it is visible from the outside.
