Extended Mathematical Programming (EMP) is an advanced framework used in optimization that integrates various components of mathematical programming, allowing for the inclusion of additional elements beyond traditional linear or nonlinear programming. EMP typically extends upon classic mathematical programming models by introducing more complex relationships and data structures, making it suited for addressing real-world problems that require more flexibility and detail in their representation.
An "excitable medium" refers to a type of physical or biological medium that exhibits a response to stimuli that can propagate excitations or waves through the medium. This concept is commonly used in various fields, including physics, biology, and chemistry, and is particularly relevant in the study of dynamic systems. ### Characteristics of Excitable Media: 1. **Threshold Behavior**: Excitable media typically have a threshold level of stimulation required to elicit a response.
Equation-free modeling is a computational approach used in scientific research, particularly in complex systems, where the underlying equations governing the dynamics of the system are either unknown, too complex to solve analytically, or too costly to simulate directly. The focus of equation-free modeling is on the system's emergent behavior rather than on deriving explicit equations that dictate that behavior.
Energy modeling is the process of creating a mathematical representation of energy consumption, generation, and related systems in buildings, industrial processes, or entire cities. These models help in understanding, predicting, and optimizing energy use and can be used for various purposes, including: 1. **Building Design and Performance**: Energy modeling is crucial in the design of energy-efficient buildings. It helps architects and engineers assess energy consumption based on factors like insulation, HVAC systems, lighting, and the overall layout of the building.
Empirical modeling is a methodological approach used primarily in the fields of science and engineering to create models based on observed data rather than purely theoretical considerations. It emphasizes the importance of observation and experience in building representations of systems, phenomena, or processes. Key aspects of empirical modeling include: 1. **Data-Driven**: Empirical modeling relies heavily on data collection and analysis. Models are formulated based on measurements and observations obtained from experiments or real-world phenomena rather than solely on established theories.
The Elementary Effects method, also known as the Morris method, is a sensitivity analysis technique used primarily in the field of uncertainty analysis and mathematical modeling. It was developed by Maxime Morris in the 1990s and is designed to evaluate the influence of input parameters on model outputs, particularly in complex simulations where traditional methods may be computationally expensive or impractical.
Electoral Calculus is an analytical tool or platform primarily used to predict and analyze election outcomes, particularly in the context of the UK electoral system. It employs various methods, including statistical models and polling data, to forecast the performance of different political parties and candidates in elections. The calculations take into account factors such as existing public opinion, historical voting patterns, demographic data, and constituency-level analysis.
The Effective Selfing Model (ESM) is a theoretical framework used in population genetics and evolutionary biology to understand the dynamics of mating systems in plants, particularly in relation to self-fertilization versus outcrossing. The key components of this model include the effects of self-fertilization on genetic diversity, the potential for inbreeding depression, and the evolutionary consequences of different mating strategies. ### Key Features of the Effective Selfing Model: 1. **Selfing vs.
Dielectric breakdown is a phenomenon that occurs in insulating materials (dielectrics) when they are subjected to a high electric field. Under normal conditions, these materials resist the flow of electric current. However, when the electric field exceeds a certain threshold, known as the dielectric breakdown strength, the material begins to conduct electricity, leading to failure of the insulating properties. ### Breakdown Mechanism: The dielectric breakdown can be explained through several mechanisms, depending on the material and the conditions.
Deterministic simulation is a type of simulation where the outcome is fully determined by the initial conditions and parameters of the model being simulated. In a deterministic simulation, if the same initial conditions are provided multiple times, the results will always be the same. This type of simulation does not incorporate randomness or probabilistic elements, meaning that there is no variability or uncertainty in the outcomes.
A Cumulative Accuracy Profile (CAP) is a graphical representation used in the field of predictive modeling and classification to evaluate the performance of a model. It helps to visualize how well a model can identify or rank instances within a dataset, typically with regard to a binary outcome (success/failure, yes/no, etc.). ### Key Concepts 1.
A computational model is a mathematical or algorithmic representation of a system or process that is used to simulate its behavior, predict outcomes, or analyze its properties. These models are built using computational techniques, allowing for complex systems to be understood and investigated through simulations on computers. Computational models can vary widely in their application and complexity, and they are commonly used in various fields, including: 1. **Physics**: To simulate physical systems ranging from particle interactions to astrophysical phenomena.
A complex system is a system composed of many interconnected parts or agents that interact with each other in multiple ways, leading to behaviors and properties that are not easily predictable from the behavior of the individual parts alone. These systems are characterized by the following features: 1. **Interconnectedness**: The components of a complex system interact in various ways, and the state of one component can significantly influence the state of others.
Compartmental neuron models are mathematical representations of neurons that divide the cell into several compartments or segments to simulate the electrical properties and dynamics of the neuron's membrane. This approach allows for a more detailed understanding of how neurons process signals, integrate inputs, and generate outputs, particularly when dealing with complex morphologies and behaviors.
A color model is a mathematical representation of colors in a standardized way, allowing consistent communication and reproduction of colors across various devices and media. Color models are designed to represent colors using numbers and can be used in graphic design, photography, printing, and other applications. Here are some commonly used color models: 1. **RGB (Red, Green, Blue)**: This model is based on the additive color theory, where colors are created by combining red, green, and blue light.
A chemical reaction model is a theoretical framework used to describe and predict the behavior of chemical reactions. These models can help chemists understand the dynamics of chemical processes, the rates at which reactions occur, and the conditions under which reactions take place. There are several types of models used to analyze chemical reactions, each emphasizing different aspects: 1. **Kinetic Models**: These focus on the rates of reactions and how they change under different conditions (e.g., concentration, temperature, pressure).
The Cebeci–Smith model is a mathematical model used in fluid dynamics to describe the behavior of turbulent boundary layers, particularly in the context of aerodynamic and hydrodynamic applications. Developed by Cebeci and Smith in the 1970s, this model provides a means for predicting the velocity profile and other characteristics of turbulent flows near the surface of a body, such as an airfoil or a ship’s hull.
The calculus of voting is a theoretical framework used to understand the decision-making process of individuals when participating in elections. The concept is associated with the work of political scientist Anthony Downs, particularly in his influential book "An Economic Theory of Democracy" published in 1957. The calculus of voting posits that individuals weigh the costs and benefits of voting to determine whether or not to participate in the electoral process.
The calculation of glass properties involves understanding and determining various physical and chemical characteristics of glass, which is a non-crystalline, solid material typically made from silica and other additives. The properties of glass can be affected by its composition, manufacturing process, and desired application. Here are some key properties of glass and how they can be calculated or measured: ### 1. **Composition Analysis** - **Mole Percent Calculations**: Determine the mole percent of each oxide in the glass composition.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
