A few short years ago, the applications for video were somewhat confined—analog was used for broadcast and cable television, VCRs, set-top boxes, televisions and camcorders. Since then, there has been a tremendous and rapid conversion to digital video, mostly based on the MPEG-2 video compression standard. Today, in addition to the legacy DV, MPEG-1 and MPEG-2 audio and video com- pression standards, there are three new high- performance video compression standards. These new video codecs offer much higher video compression for a given level of video quality.

To get started you should be somewhat familiar with the components of the system. The soccer simulation consists of three important parts: the server, the monitor and the agents.

Most circuit designers are familiar with diode dynamiccharacteristics such as charge storage, voltage dependentcapacitance and reverse recovery time. Less commonlyacknowledged and manufacturer specifi ed is diode forwardturn-on time. This parameter describes the timerequired for a diode to turn on and clamp at its forwardvoltage drop. Historically, this extremely short time, unitsof nanoseconds, has been so small that user and vendoralike have essentially ignored it. It is rarely discussed andalmost never specifi ed. Recently, switching regulator clockrate and transition time have become faster, making diodeturn-on time a critical issue. Increased clock rates aremandated to achieve smaller magnetics size; decreasedtransition times somewhat aid overall effi ciency but areprincipally needed to minimize IC heat rise. At clock speedsbeyond about 1MHz, transition time losses are the primarysource of die heating.

Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.

来自澳大利亚Qeensland大学的计算机视觉Matlab工具箱。 This Toolbox provides a number of functions that are useful in computer vision, machine vision and related areas. It is a somewhat eclectic collection reflecting the author s personal interest in areas of photometry, photogrammetry, colorimetry. It covers functions such as image file reading and writing, filtering, segmentation, feature extraction, camera calibration, camera exterior orientation, display, color space conversion and blackbody radiators. The Toolbox, combined with MATLAB and a modern workstation computer, is a useful and convenient environment for investigation of machine vision algorithms. It is possible to use MEX files to interface with image acquisition hardware ranging from simple framegrabbers to Datacube servers.

Data_Structures_and_Algorithms - These notes accompany Data Structures and Algorithms II. The course, to a large extent, follows on from Data Structures and Algorithms I. However, while DS&A I focused on fundamental datastructures, DS&A II will focus on practical algorithms, applicable to a wide range of tasks. The approach will be somewhat less formal, with a little more focus on applications.

This book is the culmination of more than 20 years of building, studying, and teaching real-time systems. The author’s travels have taken him to NASA, UPS, Lockheed Martin, the Canadian and Australian Defense Forces, MIT’s Charles Stark Draper Labs, and many other places. These visits and interactions with literally hundreds of students from such places as Boeing, Motorola, and Siemens have resulted in a wider understanding of real-time systems and particularly their real application. This book is, in essence, a compendium of these experiences. The author’s intent is to provide a practical framework for software engineers to design and implement real-time systems. This approach is somewhat different from that of other texts on the subject.

SOME BACKGROUND ON DESIGN PATTERNS The term “design patterns” sounds a bit formal to the uninitiated and can be somewhat off-putting when you first encounter it. But, in fact, design patterns are just convenient ways of reusing object-oriented code between projects and between programmers. The idea behind design patterns is simple-- write down and catalog common interactions between objects that programmers have frequently found useful.

This preface is somewhat different from prefaces found in similar books because it does not focus so much on the content of the book.We have instead chosen to write a few words about our own experiences from working with telephony services over Internet Protocol (IP). Here are our stories.
