Layered Unequal Loss Protection For Image Transmission Over Packet Loss Channels With Delay Constraints, Jianfei Cai, Xiangjun Li, Chang Wen Chen

Electrical Engineering and Computer Science Faculty Publications

In the case of high bit rate image transmission or having lots of packets, the FEC (forward error correction) encoding and decoding processes in the ULP (unequal loss protection) based schemes should be applied to individual packet groups instead of all the packets in order to avoid long processing delay. In this paper, we propose a layered ULP (L-ULP) scheme for fast and efficient FEC allocations among different packet groups and also within each packet group. The numerical results show that the proposed L-ULP scheme is quite promising for fast image transmission over packet loss networks.

Multiple Wavelet-Tree-Based Image Coding And Robust Transmission, Lei Cao, Chang Wen Chen

Electrical Engineering and Computer Science Faculty Publications

In this paper, we present techniques based on multiple wavelet-tree coding for robust image transmission. The algorithm of set partitioning in hierarchical trees (SPIHT) is a state-of-the-art technique for image compression. This variable length coding (VLC) technique, however, is extremely sensitive to channel errors. To improve the error resilience capability and in the meantime to keep the high source coding efficiency through VLC, we propose to encode each wavelet tree or a group of wavelet trees using SPIHT algorithm independently. Instead of encoding the entire image as one bitstream, multiple bitstreams are generated. Therefore, error propagation is limited within individual …

Joint Source-Channel Decoding For Mpeg-2 Video Transmission, Liuguo Yin, Weigang Chen, Jianhua Lu, Chang Wen Chen

Electrical Engineering and Computer Science Faculty Publications

Joint source-channel coding schemes have been proven to be effective ways for reliable multimedia communications. In this paper, a joint source-channel decoding (JSCD) scheme that combines the hidden Markov source (HMS) estimation and low-density parity-check (LDPC) coding is proposed for the standard MPEG-2 video transmission. The LDPC code of the proposed scheme has a near-Shannon-limit error-correcting capability, while the HMS estimator may accurately extract the residual redundancy within the MPEG-2 video stream without any prior information. Furthermore, with a joint iterative decoding algorithm, the estimated source redundancy may be well exploited by the LDPC decoder, and the channel decoding feedback …

Multiple-Description Image Coding With Distributed Source Coding And Side Information, Min Wu, Anthony Vetro, Chang Wen Chen

Electrical Engineering and Computer Science Faculty Publications

Multiple description coding (MDC) is a source coding technique that involves coding the source information into multiple descriptions. When these descriptions are transmitted over different channels in packet network or error-prone wireless environment, graceful degradation can be achieved even if part of descriptions are not received by the receiver. When MDC is applied to wavelet subband based image coding, it is possible to introduce correlation between the descriptions in each subband. In this paper, we consider using such a correlation as well as potentially error corrupted description as side information in the decoding to formulate the MDC decoding as a …

Phase Stability And Segregation In Alloy 22 Base Metal And Weldments, Jeffrey Lacombe, Shantanu A. Namjoshi, Paige Russel, Raymond E. Keeler, Amy J. Smiecinski

Publications (YM)

The current design of the waste disposal containers relies heavily on encasement in a multi-layered container, featuring a corrosion barrier of Alloy 22, a Ni-Cr-Mo-W based alloy with excellent corrosion resistance over a wide range of conditions. The fundamental concern from the perspective of the Yucca Mountain Project, however, is the inherent uncertainty in the (very) long-term stability of the base metal and welds. Should the properties of the selected materials change over the long service life of the waste packages, it is conceivable that the desired performance characteristics (such as corrosion reistance) will become compromised, leading to premature failure …

Bergland, Beatrice And Bergland, Harriet, Bronx African American History Project

Oral Histories

Beatrice Bergland and Harriet Waites of the community church of Morrisania were interviewed for the Bronx African American History Project on October 25^th 2004. They began their interview by recounting their past and present experiences with the community church of Morrisania, which was founded by Pastor William E. Thompson in 1956. He, along with community members, purchased a house on Teller Ave. for $10,000 to serve as the non-denominational church’s building which facilitated the needs of the African American community that was developing in the neighborhood and also began the formation of new, warm, active community in Morrisania.

Multiple Description Coding Based On Multiple-Bitstream Wavelet Zero-Tree Image Compression, Daewon Song, Chang Wen Chen, Lei Cao

Electrical Engineering and Computer Science Faculty Publications

Multiple description coding (MDC) is a well-known robust data compression algorithm designed to minimize the distortion caused by data loss in packet-based communication systems. Several MDC schemes for transmitting wavelet compressed images have been developed. However, these MDC schemes cannot be adopted for digital mobile wireless applications where both packet loss and bit error are present, because individual description in these MDC schemes usually does not have adequate error resilience capability to combat the bit error in transmission. In this paper, we propose an algorithm to achieve robust communication over error prone transmission channels with both packet loss and bit …

Immobilization Of Fission Iodine By Reaction With A Fullerene Containing Carbon Compound And Insoluble Natural Organic Matrix, Spencer M. Steinberg, Gary Cerefice, David W. Emerson

Separations Campaign (TRP)

The recovery of iodine released during the processing of used nuclear fuel poses a significant challenge to the transmutation of radioactive iodine. During the first two years of this program we have examined the potential of Fullerene Containing Carbon compounds (FCC) developed by KRI, and natural organic matter (NOM) as sorbents for iodine released during the reprocessing of nuclear fuel. This work involved the development of bench-scale testing of the FCC and NOM material in a simulated process off-gas environment.

Bridging The Barriers: Public Health Strategies For Expanding Drug Treatment In Communities, Ellen M. Weber

Faculty Scholarship

States around the country have begun to adopt programs to divert drug offenders from jails and prisons to community-based drug treatment services. For this strategy to succeed, local officials will need to expand the availability of outpatient and residential treatment programs and address the barriers to siting treatment services, the most significant of which are community opposition and government zoning policies that facilitate community resistance. Civil rights laws, including the Americans With Disabilities Act (ADA) and the Fair Housing Act (FHA), prohibit zoning discrimination against persons with histories of alcoholism and drug dependence and provide a solid legal foundation for …

The Subtypes Of Psychopathy And Their Relationship To Hostile And Instrumental Aggression, Diana M. Falkenbach

USF Tampa Graduate Theses and Dissertations

Psychopathy is not a diagnostic category, however theories of psychopathy have been discussed throughout psychological history. While the construct of psychopathy is associated with important psychological outcomes, there are inconsistencies in the literature with regard to correlates, etiology and treatment. These inconsistencies suggest that there may be several subtypes of psychopathy. This paper discusses the heterogeneity of psychopathy and considers the existence of psychopathic traits in nonclinical populations. Measures of etiology (Behavioral Activation System and Behavioral Inhibition System; Gray, 1985), psychopathy (Levenson's psychopathy measure; Levenson, Keihl, & Fitzpatrick, 1995) and anxiety (State Trait Anxiety Inventory; Speilberger, Gorsuch & Lushene, 1970) …

From Carlin’S Seven Dirty Words To Bono’S One Dirty Word: A Look At The Fcc’S Ever-Expanding Indecency Enforcement Role , Faith Sparr

ExpressO

The manuscript entitled: From Carlin’s Seven Dirty Words to Bono’s One Dirty Word: A Look at the FCC’s Ever-Expanding Indecency Enforcement Role examines whether the FCC, in the years since the Supreme Court’s 1978 decision in FCC v. Pacifica, has exceeded the limited holding that the Court rendered in that seminal case. Initially, the article focuses on the Pacifica holding itself, reminding the reader of the narrowness of the decision and pointing out some interesting limitations that the FCC appears to have forgotten in its recent race to crack down on speech it deems indecent. From that initial examination, the …
