Title of Dissertation: PROGRESSIVE SOURCE-CHANNEL CODING FOR MULTIMEDIA TRANSMISSION OVER NOISY AND LOSSY CHANNELS WITH AND WITHOUT FEEDBACK Vinay Chande, Doctor of Philosophy, 2004 Dissertation directed by: Professor Nariman Farvardin Department of Electrical and Computer Engineering Rate-scalable or layered lossy source-coding is useful for progressive transmission of multimedia sources, wher...

Viremic controllers and elite controllers/suppressors maintain control over HIV-1 replication. Some studies have suggested that control is a result of infection with a defective viral strain, while others suggested host immune factors have a key role. Here we document two HIV-1 transmission pairs: one consisting of a patient with progressive disease and an individual who became an elite suppres...

This study was conducted to determine a possible relationship between regular cell phone use and different human semen attributes. The history-taking of men in our university clinic was supplemented with questions concerning cell phone use habits, including possession, daily standby position and daily transmission times. Semen analyses were performed by conventional methods. Statistics were cal...

during a period of 7 years (1997-2003) we were received pairs of serum and csf of 27 suspicious clinically cases from neurology department of several hospitals in tehran. among them 7 were serologically positive for progressive rubella panencephalitis (prpe) and 2 were positive for sub acute sclerosing panencephalitis (sspe). rubella virus was isolated from 4 of 7 serologically positive cases o...

We investigate different allocation problem in mobile adhoc networks. The objective is to minimize the power consumption and end-to-end distortion when transmitting images. Therefore, we use progressive image coding in combination with unequal erasure protection. We investigate two different scenarios, independent packet loss events and path loss events. For both cases, the expected distortion ...

Within distributed computing environments, access to very large geospatial datasets often suffers from slow or unreliable network connections. To allow users to start working with a partially delivered dataset, progressive transmission methods are a viable solution. While incremental and progressive methods have been applied successfully to the transmission of raster images over the World Wide ...

Feline leukaemia virus (FeLV) infection in felids results mainly from oronasal exposure to infectious saliva and nasal secretions, but the potential for viral transmission through faeces and urine has not been completely characterized. In order to assess and compare potential FeLV transmission routes, we determined the viral kinetics in plasma, saliva, faeces and urine during early experimental...

Pulmonary arterial hypertension (PAH) is a progressive disease of the pulmonary circulation in which thrombosis, inflammation, and unbridled cellular proliferation obliterate the arterial lumen, causing progressive right heart failure and death. The pathogenesis remains enigmatic, and current therapeutic strategies are limited. In 1951, Dresdale1 published the first report of a family in which ...

In this paper, we present a multi-segment image coding scheme suitable for lossless progressive transmission over noisy or congested networks. The method is a block-wise forward-adaptive context selection technique that employs a low-complexity classification process to separate an image into multiple segments according to local statistics, so that compression efficiency by an entropy coder is ...

In this paper, we present a framework that integrates three-dimensional (3D) mesh streaming and compression techniques and algorithms into our EVE-II Networked Virtual Environments platform, in order to offer support for large-scale environments as well as highly complex world geometry. This framework allows the partial and progressive transmission of 3D worlds as well as of separate meshes, ac...
