Problem statement: Higher data transmission rate with Quality of Services (QoS) guarantee is an important objective for wireless broadband communication systems. Unlike other communication system, real-time transmission requires high data rate and good error performance to ensure good quality of service. This study describes the design problem of real-time wireless data transmission which provi...

Patching and transition patching are two techniques proposed to build efficient video-on-demand (VoD) systems. Patching works by allowing a client to playback video data from a patching stream while caching video data from another multicast video stream for later playback. The patching stream can be released once video playback reaches the point where the cached data begins, and playback contin...

This work describes the method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are used for the channel coding, providing stronger error protection than previously available codes. We use the most appropriate set of puncturin...

This research on effects of large organic debris on stream channel form and process relevant to anadromous fish habitat was along three lines of inquiry. First. new ways to evaluate discrete hydrologic environments, such as pools. riffles and debris accumulations were developed .. Experiments completed provided basic data to test a model useful for predicting hydraulic geometry of pools and rif...

This work describes a method for providing robustness to errors from a binary symmetric channel for the JPEG2000 image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are used for the channel coding, providing stronger error protection than previously available codes. We use a subset of the puncturing patterns ...

Stream depletion, which is the reduction in flow rate of a stream or river due to the extraction of groundwater in a hydraulically connected stream-aquifer system, is often estimated using numerical models. The accuracy of these models depends on the appropriate parameterization of aquifer and streambed hydraulic properties. Streambed conductance is a parameter that relates the head difference ...
