Dimensional Analysis03:40

Dimensional Analysis

44.7K
Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

48
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...

Measurement: Derived Units

43.0K
The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Units of Measurement

2.3K
Mechanical engineering is one of the oldest branches of engineering. It deals with designing, analyzing, and manufacturing machines and mechanical systems. To ensure precise and accurate calculations, units of measurement are used. They provide a standard system for expressing and comparing physical quantities.
There are various well-known historical measurement systems, such as the Babylonian system, the Roman system, the Egyptian system, the Olympian system, the British system, and the Indus...

In engineering applications, the representation of the numerical value is critical. Presenting or reporting the answer is one of the essential parts of engineering practices. Numerical calculations are performed using handheld calculators or computers since numerically accurate answers are always preferred.
The solution to a problem is obtained using different methods. While manually solving algebraic symbols is one of the most common methods, the graphical method is often preferred. Computers...

Estimation of the Physical Quantities01:05

Estimation of the Physical Quantities

4.2K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

Area of Science:

  • Computational Biology
  • Statistical Modeling
  • Bioinformatics

Background:

  • Partition Markov models (PMMs) are used for sequence analysis.
  • Bayesian Information Criterion (BIC) is a common metric for PMM selection.
  • Existing BIC metrics may not guarantee strongly consistent estimation.

Purpose of the Study:

  • To extend BIC-based metrics for strongly consistent PMM estimation.
  • To introduce and analyze Efficient Determination Criteria (EDC) for PMM selection.
  • To identify improved penalty functions within EDC.

Main Methods:

  • Generalization of BIC to the Efficient Determination Criteria (EDC) family.
  • Formal specification of EDC metric-based model selection.
  • Identification and validation of the ln(ln(n)) penalty for EDC.
  • Application of EDC metrics to dengue virus type 3 DNA sequence modeling.

Main Results:

  • EDC metrics provide a broader range of parameter penalization options than BIC.
  • The ln(ln(n)) penalty within EDC ensures strongly consistent PMM estimation.
  • The proposed metrics demonstrate utility in analyzing real-world biological data.

Conclusions:

  • EDC offers a robust framework for PMM selection with improved consistency guarantees.
  • The ln(ln(n)) penalty is a theoretically sound and practically useful choice for EDC.
  • This work advances PMM analysis, with implications for genomic and epidemiological studies.
