Vector Flow Model In Video Estimation And Effects Of Network Congestion In Low Bit-Rate Compression Standards, Balaji Ramadoss Oct 2003

Vector Flow Model In Video Estimation And Effects Of Network Congestion In Low Bit-Rate Compression Standards, Balaji Ramadoss

USF Tampa Graduate Theses and Dissertations

The use of digitized information is rapidly gaining acceptance in bio-medical applications. Video compression plays an important role in the archiving and transmission of different digital diagnostic modalities. The present scheme of video compression for low bit-rate networks is not suitable for medical video sequences. The instability is the result of block artifacts resulting from the block based DCT coefficient quantization. The possibility of applying deformable motion estimation techniques to make the video compression standard (H.263) more adaptable for bio-medial applications was studied in detail. The study on the network characteristics and the behavior of various congestion control mechanisms was …


A Study Of The Critical Condition Of A Battened Column And A Frame By Classical Methods, Jamal A.H Bekdache Jul 2003

A Study Of The Critical Condition Of A Battened Column And A Frame By Classical Methods, Jamal A.H Bekdache

USF Tampa Graduate Theses and Dissertations

Knowledge of structural stability theory is of paramount importance to the practicing structural engineer. In many instances, buckling is the primary consideration in the design of various structural configurations. The first chapter introduces a simplified treatment of the elastic stability of a battened column using classical methods without getting involved with lengthy and complicated mathematical operations. In chapter two, a treatment of the elastic stability of a frame is presented, including effects of elastic restraints. In this study, a theoretical treatment is given which although approximate, is believed to constitute a satisfactory solution of the structure.
