双BGO晶体能谱测井

Ｃ／Ｏ测井可以利用ＢＧＯ晶体探测效率高的特点，在其探测器部分放置两个探测器，称为双探测Ｃ／Ｏ测井仪，长短源距两个探头所测谱数据进行补偿，有效地去除了井眼条件的影响，提高了测量精度和油水差值，更加有产地分油水层，并有望能在低孔隙度的地层中使用Ｃ／Ｏ测井仪器。     

基于ATM的可变比特率视频传输

在目前采用的同步传输模式(STM)网络中,信道速率是固定的,这样由视频图像编码器产生的时变比特流无法直接接入固定比特率(CBR)信道。由于ATM网络所具有的异步传输,统计复用和支持QoS保证的特点,使之成为适合可变比特率(VBR)视频传输的网络技术。本文描述了VBR视频源的统计模型,论述了在ATM环境下的QoS控制、统计复用与带宽分配等问题。     

Design and analysis of a video-on-demand server

The availability of high-speed networks, fast computers and improved storage technology is stimulating interest in the development of video on-demand services that provide facilities similar to a video cassette player (VCP). In this paper, we present a design of a video-on-demand (VOD) server, capable of supporting a large number of video requests with complete functionality of a remote control (as used in VCPs), for each request. In the proposed design, we have used an interleaved storage method with constrained allocation of video and audio blocks on the disk to provide continuous retrieval. Our storage scheme interleaves a movie with itself (while satisfying the constraints on video and audio block allocation. This approach minimizes the starting delay and the buffer requirement at the user end, while ensuring a jitter-free display for every request. In order to minimize the starting delay and to support more non-concurrent requests, we have proposed the use of multiple disks for the same movie. Since a disk needs to hold only one movie, an array of inexpensive disks can be used, which reduces the overall cost of the proposed system. A scheme supported by our disk storage method to provide all the functions of a remote control such as “fast-forwarding”, “rewinding” (with play “on” or “off”), “pause” and “play” has also been discussed. This scheme handles a user request independent of others and satisfies it without degrading the quality of service to other users. The server design presented in this paper achieves the multiple goals of high disk utilization, global buffer optimization, cost-effectiveness and high-quality service to the users.

磁介质涂层圆锥喇叭天线的设计方法

通过在圆锥喇叭内壁加磁介导涂层的方法，成功地设计了具有低副瓣、低交叉极化和方向图对称的喇叭天线。该磁介质涂层既是良导电体，又是良导磁体。通过选择合适的喇叭张角，该喇叭天线与波纹喇叭性能相同，而且比波纹喇叭设计简单。
