A survey of isolation techniques

چکیده

The general purpose computer has become pervasive and is supporting an increasing number of functions, including music, video, gaming, communications, banking, business, process control, and critical in frastructure. The use of a single computer for mult iple functions, and the interconnection of mult iple computers through a common network have reduced the isolation that protected such functions in the past. If we are to use common systems for multip le functions, we need mechanis ms that provide the isolation needed to protect each function from interference by others. Without such isolation, vulnerabilities and mis-trust in any part of the system can propagate and compromise the rest of the system. Isolation techniques form an integral part of security in systems and networks. This work surveys isolation techniques for operating systems and networks and describes systems built using those techniques. An intuitive taxonomy is proposed for organizing these techniques. The paper aims to provide a crit ical understanding of what already exists and what needs to be done with respect to isolation security for building next-generation secure systems.

Base Isolation Systems – A State of the Art Review According to Their Mechanism

Seismic isolation is a method to reduce the destructive effects of earthquakes on a structure in which the structure is separated from its foundation by devices called seismic isolators. As a result, the horizontal movements of the earthquake transmitted to the structure are reduced. The seismic isolation is used for both newly constructed structures as well as for retrofitting the existing bui...

ISOLATION AND STRUCTURAL ELUCIDATION OF THE FIRST KNOWN C-HOMOPROTOBERBERINE

A novel C-homoprotoberberine alkaloid, Hediamine (2), has been isolated from the roots of Berberis actinucantha (Berberidaceae). Conclusive proof for the structure of hediamine was obtained by its comparison with the isomeric lactam (4), by chemical transformation, and by means of spectroscopic techniques (UV, IR, MS, NMR).

Techniques used for the isolation and characterization of extracellular vesicles: results of a worldwide survey

Extracellular vesicles (EVs) represent an important mode of intercellular communication. Research in this field has grown rapidly in the last few years, and there is a plethora of techniques for the isolation and characterization of EVs, many of which are poorly standardized. EVs are heterogeneous in size, origin and molecular constituents, with considerable overlap in size and phenotype betwee...
