We describe three disk scheduling algorithms that can be used in a multimedia server for sustaining a number of heterogeneous variable-rate data streams. A data stream is supported by repeatedly fetching a block of data from the storage device and storing it in a corresponding buffer. For each of the disk scheduling algorithms we give necessary and sufficient conditions for avoiding underand ov...

Product units in service may be discarded even before they have failed. This paper discusses the need to consider such discarded units in analyzing eld failure data. Approaches based on maximum likelihood (ML) and conventional cumulative hazard (CH) methods are described and evaluated for their accuracy in estimating the parameters of failure time distributions. Simulation results showed that t...

In this paper, we summarize some eecient techniques and methods which have been developed for high rate multi-media wireless communications. The overall structure of a wireless cellular system which provides integrated services is proposed. Spread spectrum DS-CDMA and modiied ATM techniques are chosen to support the system. Ef-cient signalling and error control coding methods are investigated. ...

In this paper, we present a concatenated coding scheme for a high rate 2 × 2 multiple-input multiple-output (MIMO) system over slow fading channels. The inner code is the Golden code and the outer code is a trellis code. Set partitioning of the Golden code [2] is designed specifically to increase the minimum determinant. The branches of the outer trellis code are labeled with these partitions. ...
