The PLC Cycle

-The PLC is initialized internally when the power is turned on
-If no error are detected, the overseeing processes , program execution, I/O refreshing, and peripheral device servicing are executed consecutively (cyclically)
-The average cycle time can be monitor from a Peripheral Device

Self-diagnosis Functions

-The PLC is equipped with a variety of self-diagnosis function to help identify and correct errors that might occur and reduce down time

Cloaker: Hardware Supported Rootkit Concealment

Abstract
Rootkits are used by malicious attackers who desire to run software on a compromised machine without being de- tected. They have become stealthier over the years as a consequence of the ongoing struggle between ....etc

Locally Adaptive Passive Error Concealment
for Wavelet Coded Images

Joost Rombaut, Aleksandra Piˇzurica, Member, IEEE, and Wilfried Philips, Member, IEEE



Abstract—

This letter presents a novel locally adaptive error concealment
method for subband coded images. For each lost low-frequency
coefficient, we estimate the optimal interpolation weights
from its neighborhood. The calculation of the interpolation weights
is optimized in the mean squared error sense, and it takes into acco ....etc

Packet loss concealment using audio morphing

Presented By:
Franck Bouteille¹
Pascal Scalart²
Balazs Kövesi²


Motivation


In packet data networks, excess traffic leads to delays or loss in delivery of information. In voice communication, long delays are intolerable and network delay budgets have strong influence on the design of packet voice systems.
To increase the tolerance of packet voice systems to lost packets some techniques have been developed.
These techniques do not use the a posteriori informati ....etc

ABSTRACT
In This Seminar An adaptive watermarking capacity analysis in the spatial domain and wavelet domain has to be present. The relationship between the watermarking capacity and the watermark detection error rate is also discussed. The discussion of watermark detection error rate will help us finding the ways to embed more watermark messages while keeping an acceptable detection error rate, it is useful for the design of the general algorithms of watermarking and detection. The watermarking system is analyzed based on the channel capacity ....etc

Abstract

Here, students learn how error correction coding makes wireless communications more robust in the presence of noise. In the laboratory, the students work in Matlab to code two simple error correction schemes, and simulate their use in a wireless channel. In the process, they learn concepts such as bit error rate, and see the trade-off between processing time and robustness.

Introduction

The packet transport service provided by representative packet-switched networks, including IP networks, is not reliable and the quality-of-service cannot be guaranteed. Packets may be lost due to buffer overflow in switching nodes, be discarded due to excessive bit errors and failure to pass the cyclic redundancy check at the page link layer, or be discarded by network control mechanisms as a response to congestion somewhere in the network. Forward Error Correction coding has often been p ....etc

Introduction

Sensors integrated into structures, machinery, and the environment, coupled with the efficient delivery of sensed information, could provide tremendous benefits to society. Potential benefits include: fewer catastrophic failures, conservation of natural resources, improved manufacturing productivity, improved emergency response, and enhanced homeland security . However, barriers to the widespread use of sensors in structures and machines remain. Bundles of lead wires and fiber optic ....etc

Hi I am Jahnavi.I want to do project in image processing. I have selected the main topic like error concealment. I need some matlab programs for that related topic. I em trying to implement IEEE paper published in 2006, Adaptive MAP Error Concealment for Dispersively Packetized Wavelet-Coded Images.

Abstract—In this paper, we present an adaptive maximum a posteriori (MAP) rror concealment algorithm for dispersively packetized wavelet-coded images. We model the subbands of a waveletcoded image as Markov random fields, and use the edge ....etc
