Distribution Reliability and Automation01:25

Distribution Reliability and Automation

402
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

262
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Role-Based Identity01:21

Role-Based Identity

99
Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Transmission-based Precautions II: Airborne and Protective Environment

1.7K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Area of Science:

  • Computer Science
  • Information Security
  • Human-Computer Interaction

Background:

  • Critical information and services necessitate robust access control systems to prevent malicious activities and significant user losses.
  • Access control has evolved from simple passwords to advanced methods like smart cards, certificates, tokens, and biometrics, each with limitations.
  • Balancing security with system usability is a key challenge, often leading to the continued prevalence of password-based authentication.

Purpose of the Study:

  • To present a new password-based access control system.
  • To enhance password security while minimizing negative impacts on system usability.
