Constraints and Statical Determinacy01:26

Constraints and Statical Determinacy

755
In structural engineering, the equilibrium of a system is not only determined by its equations of equilibrium but also with the help of constraints. Constraints refer to restrictions on the motion of a system. The proper combinations of constraints can minimize the total number of constraints needed to maintain a system in mechanical equilibrium. When this happens, the system is said to be statically determinate. For such systems, the unknown reaction supports can be estimated using equilibrium...

Combinatorial Gene Control02:33

Combinatorial Gene Control

8.6K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Compensation Mechanisms01:28

Compensation Mechanisms

1.5K
The human body employs intricate mechanisms to counteract changes in blood pH, preventing conditions like acidosis (pH < 7.35) and alkalosis (pH > 7.45). These compensatory responses aim to restore normal arterial blood pH by engaging respiratory or renal systems, depending on the source of the imbalance.
Respiratory Compensation
This mechanism addresses metabolic-induced pH imbalances by adjusting breathing rates. Respiratory compensation begins within minutes of detecting a pH...

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

117
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
In individual population analyses, different algorithms are employed, such as Cauchy's method, which uses a...

Design Example: Managing Concrete Workability01:14

Design Example: Managing Concrete Workability

135
This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.

Heuristics01:21

Heuristics

164
Heuristics are problem-solving strategies that use mental shortcuts to simplify decision-making. Unlike algorithms, which must be followed precisely to achieve a correct result, heuristics offer a general problem-solving framework. They save time and energy but can sometimes lead to less rational decisions.
People often rely on heuristics when faced with an overload of information, limited time, low importance of the decision, limited information, or when a heuristic readily comes to mind. For...

Area of Science:

  • Computer Science
  • Information Security
  • Operations Research

Background:

  • Effective human capital utilization is vital for business success, necessitating reorganization for non-productive or retiring employees.
  • Task reassignment must consider employee capabilities and adhere to security constraints, including dependencies on shared task access.
  • Attribute Based Access Control (ABAC) is emerging as a standard for access control policies in commercial systems.

Purpose of the Study:

  • To address the challenge of automating employee-to-task assignment in large organizations.
  • To define and analyze the Employee Replacement Problem (ERP) for optimizing workforce allocation.
  • To ensure security constraints are maintained during organizational restructuring and task reassignment.

Main Methods:

  • Formalizing organizational policies and constraints using Attribute Based Access Control (ABAC).
  • Defining the Employee Replacement Problem (ERP) to determine if a smaller employee set can replace a larger one securely.

  • Experimental evaluation demonstrates the efficiency of the proposed solution on diverse datasets.

Conclusions:

  • Automating employee-to-task assignment is crucial for managing large-scale organizations.
  • The ERP framework, solved via CNF-SAT, provides an efficient method for secure organizational restructuring.
  • The findings support the use of ABAC for modeling organizational policies and enabling automated workforce management.
