Secure spread spectrum watermarking for multimedia

by Ingemar J. Cox, Joe Kilian, F. Thomson Leighton, Talal Shamoon - IEEE TRANSACTIONS ON IMAGE PROCESSING , 1997
"... This paper presents a secure (tamper-resistant) algorithm for watermarking images, and a methodology for digital watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i.i.d.) Gauss ..."

.i.d.) Gaussian random vector that is imperceptibly inserted in a spread-spectrum-like fashion into the perceptually most significant spectral components of the data. We argue that insertion of a watermark under this regime makes the watermark robust to signal processing operations (such as lossy compression

COSMOLOGICAL PARAMETERS: FASHION AND FACTS

by A. Blanchard , 2003
"... We are at a specific period of modern cosmology, during which the large increase of the amount of data relevant to cosmology, as well as their increasing accuracy, leads to the idea that the determination of cosmological parameters has been achieved with a rather good precision, may be of the order ..."

matching of the power spectrum of matter fluctuations. However, the necessary introduction of a non zero cosmological constant is an extraordinary new mystery for physics, or more exactly the come back of one of the ghost of modern physics since its introduction by Einstein. Here, I would like to emphasize

Behavioral theories and the neurophysiology of reward,

by Wolfram Schultz - Annu. Rev. Psychol. , 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

Lane, and unfailingly end up in the Mill pub by the river Cam. The known attraction inducing the pleasant anticipation is a pint of Hobgoblin. Hobgoblin's provocative ad reads something like "What's the matter Lager boy, afraid you might taste something?" and refers to a full

TETANUS TOXOID IN AN MHC-RESTRICTED FASHION

by Cd+ T Lymphocytes Recognize, Danuta Kozbor, Giorgio Trinchieri, Dimitri S Monos, Masaharu Isobe, Giandomenico Russo, Jo Ann Haney
"... Although the TCR-y/S complex contains relatively few germline V gene segments (1, 2), the TCR-y diversity is increased by N nucleotide incorporation at the VJ junction (1), and TCR-Sjunctional diversity is high, with the use of at least two tandemly arranged Db elements and extensive N nucleotide in ..."

incorporation (2). Because adult TCRy/S shows the most extensive dichotomy with respect to the spectrum of V region diversity compared with junctional diversity, Davis and Bjorkman (3) have suggested that the ligand for y/S heterodimer will consist ofa peptide fragment of antigen in association with an MHC-like

Inhibition of apoptosis and prolongation of neutrophil functional longevity by inflammatory mediators

by Alison Lee, Moira K. B. Whyte, Christopher Haslett - J. Leukoc. Biol , 1993
"... Abstract: Neutrophil apoptosis leads to macrophage ingestion of intact senescent neutrophils. This may represent a neutrophil removal mechanism that is important both in the control of inflammatory tissue injury and for the normal resolution processes of inflammation. Because apoptosis is likely to ..."

Virtual Fashion- Tracking and Analyzing Cultural Dispersion on the World Wide Web

by School Of Architecture, Judith S. Donath, Ta-gang Chiou, Ta-gang Chiou
"... In the real world, people clothe themselves in garments whose cut and design encodes information about their social identity. This encoding changes temporally as the design spreads throughout a population: this is the basis of "fashion." A similar sense of fashion has emerged on the World ..."

Fashion as a Marketing Tool and Its Communication Aspect in Developing Markets Fashion as a Marketing Tool and Its Communication Aspect in Developing Markets Fashion as a Marketing Tool and Its Communication Aspect in Developing Markets

by Dr Engin Fatma , Alpat , Dr Ziya Yusuf , Aksu , Dr Engin Fatma , Dr Alpat , Ziya Yusuf , Aksu
"... Abstract In this article the idenfication of a fashion product, its variability and the analyses of fashion as an industrial design will be discussed within the framework of fashion product marketing. The process of product creation is closely related to the economic, sociological and psychological ..."

that fashion actualizes ongoing changes. -Relationships between Fashion- Product-Marketing: It is especially important to define the word new by how it manifests itself rather than the techical meaning. Fashion is the slave of imagination and just like in nostalgy movement it is inspired by the past as well

Indicators for Social and Economic Coping Capacity - Moving Toward a Working Definition of Adaptive Capacity”, Wesleyan-CMU Working Paper.

by Gary Yohe , Richard S J Tol , Gary Yohe , 2001
"... Abstract This paper offers a practically motivated method for evaluating systems' abilities to handle external stress. The method is designed to assess the potential contributions of various adaptation options to improving systems' coping capacities by focusing attention directly on the u ..."

to local custom alone. The stock of human capital (Determinant 4) could be a local characteristic, as well, but its local manifestation would likely be driven in large measure by macro-scale forces such as national support of local education. The stock of social capital (Determinant 5) and efficacy of risk-spreading

Jammer Excision in Spread Spectrum Communications via Discrete Evolutionary Transform

"... In this paper, we propose time-frequency jammer exci-sion techniques for direct sequence spread spectrum com-munications. One method is based on the estimation of the instantaneous frequency (IF) of each of the chirp jam-mer components using a combination of the discrete evolu-tionary and the Hough ..."

Narow-band interference suppression in spread spectrum CDMA communications using pipelined recurrent neural network

by Po-rong Chang, Jen-tsung Hu - IEEE Trans. Vehicular Technology , 1999
"... Abstract—This paper investigates the application of pipelined recurrent neural networks (PRNN’s) to the narrow-band interfer-ence (NBI) suppression over spread-spectrum (SS) code-division multiple-access (CDMA) channels in the presence of additive white Gaussian noise (AWGN) plus non-Gaussian observ ..."
