Masking and Demasking Agents01:19

Masking and Demasking Agents

4.1K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Stereotype Content Model02:16

Stereotype Content Model

13.1K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Principle of Virtual Work: Problem Solving

1.9K
The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.
To apply the principle of virtual work,...

Virtual Work01:20

Virtual Work

1.6K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Area of Science:

  • Computer Science
  • Cybersecurity
  • Cloud Computing

Background:

  • Cloud computing offers infrastructure management benefits but faces privacy risks from side-channel attacks.
  • User isolation is crucial for mitigating these cloud-based privacy leakage threats.

Purpose of the Study:

  • To propose a novel virtual machine (VM) management scheme to enhance isolation and defend against side-channel attacks in cloud environments.
  • To introduce the Security-awareness VMs Management Scheme (SVMS) for improved user data protection.

Main Methods:

  • Defined user constraint relations using Aggressive Conflict of Interest Relation (ACIR) and Aggressive In Ally With Relation (AIAR).
  • Developed four isolation rules based on the Chinese Wall policy.
  • Designed VM placement and migration algorithms to enforce isolation between conflicting users.

Main Results:

  • The proposed SVMS effectively guarantees isolation between virtual machines (VMs) belonging to conflicting users.
  • Experimental evaluation demonstrated the efficiency of SVMS in enhancing VM isolation.

Conclusions:

  • SVMS provides a robust solution for mitigating side-channel attacks in cloud computing through enhanced VM isolation.
  • While a slight decrease in resource utilization was observed, the security benefits of SVMS are significant.
