A new method is introduced to analyze lossy Inhomogeneous Planar Layers (IPLs) for both TE and TM polarizations in this paper. The IPLs are subdivided into several thin linear layers instead of uniform ones. The chain parameter matrix of linear layers is obtained by expressing the electric and magnetic fields in power series expansion. This method is applicable to all arbitrary lossy IPLs. The ...

Universal source codes achieve the optimal performance without apriori knowledge of the source statistics. The problem of universal lossy source coding for general non-stationary processes is considered here. Fixed rate and fixed distortion lossy source codes derived from the Lempel-Ziv scheme are shown to be universal for non-stationary processes with abstract alphabets. We define the rate dis...

An algorithm for lossy compression of scanned map images is proposed. The algorithm is based on color quantization, efficient statistical context tree modeling and arithmetic coding. The ratedistortion performance is evaluated on a set of scanned maps and compared to JPEG2000 lossy compression algorithm, and to ECW, which is a commercially available solution for compression of satellite and aer...

Ferrites and lossy ceramics, used in HOM (higher order mode) loads for superconducting accelerators, have shortcomings such as poor batch-to-batch reproducibility of electromagnetic properties, extremely low electric conductivity at cryogenic temperatures leading to accumulation of charge on the material surface, brittleness, which may cause contamination of the nearby SRF cavities by lossy dus...

This document presents a security threat analysis for the Routing Protocol for Low-Power and Lossy Networks (RPLs). The development builds upon previous work on routing security and adapts the assessments to the issues and constraints specific to low-power and lossy networks. A systematic approach is used in defining and evaluating the security threats. Applicable countermeasures are applicatio...

Standard compliant enhancements of the emerging H.264/AVC coding algorithm for transmission over lossy IP-based networks are described with the error resilience features being presented in greater detail. Standard compliant encoder and decoder enhancements as well as the exploitation of transport layer mechanisms to improve the quality in packet lossy environments are presented. Different schem...

We propose a protocol for conditional suppression of losses in direct quantum state transmission over a lossy quantum channel. The method works by noiselessly attenuating the input state prior to transmission through a lossy channel followed by noiseless amplification of the output state. The procedure does not add any noise; hence, it keeps quantum coherence. We experimentally demonstrate it i...

TTA especially with the filtering of higher frequencies in cables longer than 3.2 m resulting in increased signal Water content and electrical conductivity of soils are routinely rise time (Heimovaara, 1993; Noborio, 2001). Timing or determined using time-domain reflectometry (TDR) based on analysis length measurement errors associated with finite pixel of signal travel time and attenuation alo...

Reliable transmission of compressed video in a packet lossy environment cannot be achieved without error recovery mechanisms. We describe an e ective method for increasing error resilience of video transmission over packet lossy networks such as the Internet. Intra coding (without reference to a previous picture) is a well known technique for eliminating temporal error propagation in a predicti...

We shed light on the accuracy of particle trajectories in turbulent vector fields when lossy data compression is used. So far, data compression has been considered rather hesitantly due to supposed accuracy issues. Motivated by the observation that particle traces are always afflicted with inaccuracy, we quantitatively analyze the additional inaccuracies caused by lossy compression. In some exp...
