Mesh Analysis with Current Sources01:10

Mesh Analysis with Current Sources

1.8K
Mesh analysis becomes simpler when analyzing circuits with current sources, whether independent or dependent. The presence of current sources reduces the number of equations required for analysis. Two cases illustrate this:
Current Source in One Mesh: The analysis process is straightforward when a current source is found in only one mesh within the circuit. Mesh currents are assigned as usual, with the mesh containing the current source excluded from the analysis. Kirchhoff's voltage law...

Mechanistic Models: Compartment Models in Individual and Population Analysis

154
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Nodal Analysis with Voltage Sources

1.6K
Nodal analysis is a remarkably effective method used in electrical engineering to simplify the analysis of complex circuits, including those with dependent or independent voltage sources. Its strength lies in its systematic approach to breaking down circuits into manageable components, making it easier for engineers to understand and solve.
Consider a circuit that contains four resistors and two voltage sources, as shown in Figure 1. One of these voltage sources is connected between a...

Multiple Voltage Sources01:25

Multiple Voltage Sources

1.5K
Generally, a single battery is not enough to power some devices. In such cases, batteries can be combined in two ways: in series or in parallel.
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
Batteries are...

Multicompartment Models: Overview01:14

Multicompartment Models: Overview

365
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Mechanistic Models: Overview of Compartment Models

253
Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

    • Optics and Photonics
    • Classical Optics
    • Coherence Theory

    Background:

    • Generalized Schell-model sources are widely used in optical beam propagation studies.

    • To demonstrate unique propagation characteristics of light beams from these sources.

    Main Methods:

    • Mathematical formulation of generalized Schell-model sources with position-dependent CDC.
    • Analysis of the resulting radiation fields in the Fresnel and far zones.
    • Illustrative examples using two newly devised classes of CDCs.

    Main Results:

    • New classes of complex degree of coherence (CDC) were successfully devised.
    • The generated light beams exhibit lateral self-shifting.
    • Self-focusing effects with controllable focal lengths were observed.

    Conclusions:

    • The generalized Schell-model offers a flexible framework for designing optical sources.
    • Novel CDC functions can engineer unique beam propagation properties.
    • Source parameters like non-trivial phase and power 'n' allow control over beam behavior, including focusing.
