Recovering from attacks is hard and gets harder as the time between the initial infection and its detection increases. Which files did the attackers modify? Did any of user data depend on malicious inputs? Can I still trust my own documents or binaries? When malcode has been active for some time and its actions are mixed with those of benign applications, these questions are impossible to answe...

Due to brisk growth of data volume in many organizations, large-scale data processing became a demanding topic for industry as well as for academic fields. Hadoop is widely adopted in Cloud Computing environment for unstructured data. Hadoop is an open source, a java based distributed computing framework, and supports large-scale distributed data processing. In the recent years, Hadoop Distribu...

Most Manufacturing Control Systems 0VICS) commercially available lack support for error recovery. Even normal constructs for encoding exception handling, a natural part of many computer languages, are absent. Although several proposals have been suggested, there are still shortcomings: ̄ although many proposals contain support for error recovery or fault tolerant operation, most of the support o...

This paper deals with human error resistance. In the first part of it, a short state-ofthe-art of human error resistance, i.e., error prevention and error correction will be presented. Then, error correction, which is usually divided into three sequential tasks: detection, explanation, and recovery will be described. The second part of the paper will put emphasis on error recovery, which is our...

A critical component of disaster recovery planning is testing, which involves verification of the effectiveness of the DR solutions. Currently, there are several limitations that plagues disaster testing efforts such as the inability to create realistic disaster scenarios and test them in a production environment. Cyber Range Concept of Operations (CONOPS) presents an opportunity for overcoming...

RECOVERY TECHNIQUES TO IMPROVE FILE SYSTEM RELIABILITY Swaminathan Sundararaman We implement selective restart and resource reservation for commodity file systems to improve their reliability. Selective restart allows file systems to quickly recover from failures; resource reservation enables file systems to avoid certain failures altogether. Together they enable a new class of more robust and ...

For confining potentials of the form q(r) = r+ p(r), where p(r) decays rapidly and is smooth for r > 0, it is proved that q(r) can be uniquely recovered from the data {Ej , sj}∀j=1,2,3..... Here Ej are energies of bound states and sj are the values u ′ j(0), where uj(r) are the normalized eigenfunctions, ∫∞ 0 u 2 jdr = 0. An algorithm is given for finding q(r) from the knowledge of few first da...

Degradation of urban environment and health hazard is directly associated with the unscientific handling of Municipal solid waste of India. Urbanization also contribute intensify Municipal solid waste generation. Source segregation of solid waste not only the fact to converge but also possible in maximum resource recovery from the waste. Waste management is a problem due to the ineffective mana...
