Impact of Schemas01:30

Impact of Schemas

174
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Collisions in Multiple Dimensions: Problem Solving

5.2K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Model Approaches for Pharmacokinetic Data: Distributed Parameter Models

214
Pharmacokinetic models are mathematical constructs that represent and predict the time course of drug concentrations in the body, providing meaningful pharmacokinetic parameters. These models are categorized into compartment, physiological, and distributed parameter models.
The distributed parameter models are specifically designed to account for variations and differences in some drug classes. This model is particularly useful for assessing regional concentrations of anticancer or...

Actuarial Approach01:20

Actuarial Approach

267
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Collisions in Multiple Dimensions: Introduction

6.4K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...

Area of Science:

  • Computer Science
  • Information Security

Background:

  • Organizations face challenges in managing diverse and evolving security policies.
  • Attribute Based Access Control (ABAC) offers flexible policy enforcement but lacks comprehensive integration with existing systems.
  • Migrating existing security policies to ABAC and managing multiple policy types uniformly is complex.

Purpose of the Study:

  • To propose a unified solution for concurrent specification, enforcement, and management of various access control policies, including ABAC.
  • To address the difficulties in migrating existing policies to ABAC and integrating them with other organizational policies.
  • To develop a flexible and efficient system for unified security policy management.

Main Methods:

  • A multi-dimensional, multi-granular data model and a unified database schema, inspired by data warehousing, are presented.
  • Policies are stored as in-memory data to optimize access request evaluation time.
  • A meta-policy approach is introduced for combining multiple access control policies.
  • An administrative schema is proposed for managing diverse administrative policies.

Main Results:

  • The proposed unified database schema effectively represents and manages different types of access control policies.
  • Storing policies in-memory significantly reduces the execution time for access request evaluations.
  • The meta-policy approach enables effective combination of disparate security policies.
  • Experimental results validate the viability and efficiency of the proposed unified approach.

Conclusions:

  • The developed solution offers a flexible and comprehensive approach to unified security policy management.
  • The system successfully integrates ABAC with other policy types, simplifying organizational security.
  • The use of a data warehouse-like schema and in-memory storage enhances performance and manageability.
