Mathematical modeling provides answers to real world questions like “Which recycling program is best for my city?” “How will a flu outbreak affect the US,” or “Which roller coaster is the most thrilling?” In math modeling, you’ll use math to represent, analyze, make predictions or otherwise provide insight into real world phenomena. This is the first episode in this new math modeling video series and introduces the modeling process, setting the stage for the next six videos which dive into the specific steps to modeling.

Mathematical models are key tools that are used both to advance our understanding of atmospheric physical and chemical processes and to provide forecast information, just like for meteorology. What are the underlying principles? How do they work? What are their limitations? These are among the questions covered. This movie is the first part of the series of two talks.

Tuning a PID controller requires that you have a representation of the system you’re trying to control.
- Download Code Examples to Learn How to Automatically Tune PID Controller Gainshttps: http://bit.ly/2HKBh12
This could be the physical hardware or a mathematical representation of that hardware.
If you have physical hardware, you could guess at some PID gains, run a test to see how it performs, and then tweak the gains as necessary. This guess-and-check brute force tuning method might work, but you have other, more precise, options available if you have a mathematical model of the system. Therefore, this video presents three different ways to model your system so that you can take advantage of each of these methods when tuning your controller.
The first method uses a detailed understanding of the system to develop the model with first principles. The second method uses system identification, the known input, and resulting output signal to fit the data to the model structure of your choice. The third method creates a model by linearizing an existing nonlinear model around a given operating point.
With any of these models, you can start the process of developing and tuning a PID controller.

This is the first video of a two-part episode.
Model the physical systems of your racecar and learn about the variety of modeling methods that fit your needs. This is the first video of a two-part episode. Sebastian Castro and Christoph Hahn, of MathWorks, introduce a variety of modeling approaches and demonstrate them in Simulink®.
Sebastian describes the differences between plant models and algorithmic models and how to decide which model is best for your situation. Plant models are a virtual prototype of a real physical system that you are trying to model, whereas an algorithmic model is where you can test your algorithms on your simulation. With Simulink you can combine these two types of modeling and use available analysis tools to then further improve your design.
The many varieties of modeling include those using purely data or purely mathematical equations, and then combinations using both of these methods. Sebastian starts by looking at a suspension system using the mathematical modeling method to see how easy-to-understand equations can be used to create a model. With that same suspension system, he then moves the focus away from equations and demonstrates component-based modeling using Simscape™. This is a tool for component-based modeling that uses blocks which have the equations in the background. The benefit of this method is that you do not need to know as much detail about the equations.

The Ebola epidemic in West Africa has spurred an international response. This response has been strongly influenced by epidemiological models that predicted a devastating rise in cases without large-scale changes in behavior and intervention. In this talk, I introduce the mathematical principles underlying predictions of the rate and scope of a disease epidemic. I then explain how such principles have been applied to forecasting Ebola virus disease (EVD) dynamics and identifying the type and scale of necessary control. One control mechanism involves influencing behavior and social norms to limit post-death transmission, e.g., during burial ceremonies of individuals who died from EVD. Post-death transmission for EVD has been recognized for over 10 years, yet its relative importance in the current epidemic remains uncertain. I conclude my talk with an analysis of ongoing challenges in estimating the relative importance of post-death transmission from early-stage epidemic data. I show why such estimation is hard and yet, nonetheless, why controlling post-death transmission is likely to have a substantial effect on short- and long-term epidemic outcomes.

The mathematical modelling and simulation of human motion in the context of computer assisted surgery is a challenging task. For example, the design of fixation devices in surgery and joint prostheses requires a realistic modelling of the healing process and a quantitative description of displacements and stresses during different gaits, e.g., walking and stair climbing. A realistic physical and mathematical modelling in combination with efficient simulation techniques would open exciting medical perspectives far beyond osteotomic surgery.
Mathematical models coupling all possibly relevant biomechanical aspects of human motion are clearly not manageable. Existing musculo-skeletal models for human motion are typically based on a rigid body approximation of human bones leading to multibody systems of differential-algebraic equations (DAEs). Joints and muscles are incorporated by simple models. To study the local elastic behavior of bones, finite element methods (FEM) are used for 3D partial differential equations (PDEs). In applications such as prostheses or fixation devices, mechanical contact problems occur. Quite often, contact problems are just neglected for computational complexity reasons. If at all, they are usually treated via penalty methods or heuristic techniques. Heterogeneous dynamical DAE/PDE models, which would actually be required, seem to be not available yet.

Lotka Volterra predator prey model - In this lecture lotka voltera competition model is explained with equation. This is a two part video. in the first part, Lotka Voltera competition model is explained and in the second part Lotka Voltera predator prey model is exaplained with equation.
INTERSPECIFIC COMPETITION: LOTKA-VOLTERRA
Introduction: Interspecific competition refers to the competition between two or more species for some limiting resource. This limiting resource can be food or nutrients, space, mates, nesting sites-- anything for which demand is greater than supply. When one species is a better competitor, interspecific competition negatively influences the other species by reducing population sizes and/or growth rates, which in turn affects the population dynamics of the competitor. The Lotka-Volterra model of interspecific competition is a simple mathematical model that can be used to understand how different factors affect the outcomes of competitive interactions.
Importance: Competitive interactions between organisms can have a great deal of influence on species evolution, the structuring of communities (which species coexist, which don't, relative abundances, etc.), and the distributions of species (where they occur). Modeling these interactions provides a useful framework for predicting outcomes.

For hundreds of years, scientists were developing strong theories and rigorous mathematical models to explain patterns and dependencies in data and processes around us. Today instead of modeling some features of data by ourselves we rely on deep neural networks and they don't let us down. So, the natural question arises: do we really need human experts to describe the world mathematically or let's just let AI do all the work?
In this talk, we will connect dots between generative neural networks (GANs) and mathematical models like ODEs (ordinary differential equations) for ECG analysis: a classical area driven by pure mathematical models for decades. We analyze empirically what human experts did and what neural networks have learned by themselves and will try to understand, how close we are to fully rely on AI in ECG analysis and other areas.

In this talk, methods that we have designed to analyze and help to identify certain protein regulatory networks will be presented. Hybrid automata represent one suitable modeling framework, as the protein concentration dynamics inside each cell are modeled using linear differential equations; inputs activate or deactivate these continuous dynamics through discrete switches, which themselves are controlled by protein concentrations reaching given thresholds. We present an iterative refinement algorithm for computing discrete abstractions of a class of symbolic hybrid automata, and we apply this algorithm to a model of multiple cell Delta-Notch protein signaling. The results are analyzed to show that novel, non-intuitive, and biologically interesting properties can be deduced from the computation, thus demonstrating that mathematical modeling which extrapolates from existing information and underlying principles can be successful in increasing understanding of some biological systems.

After the good princess had breathed her last and had been honorably buried, Tebaldo indulged in the thought of wedding again, but he bore well in mind the promise he had made to his wife, and was firmly resolved to keep her saying. However, the report that Tebaldo, Prince of Salerno, was seeking another mate soon got noised abroad, and came to the ears of many maidens who, in worth and in estate, were no whit his inferiors; but Tebaldo, whose first care was to fulfil the wishes of his wife who was dead, made it a condition that any damsel who might be offered to him in marriage should first try on her finger his wifes ring, to see whether it fitted, and not having found one who fulfilled this condition -- the ring being always found too big for this and too small for that -- he was forced to dismiss them all without further parley. Now it happened one day that the daughter of Tebaldo, whose name was Doralice, sat at table with her father; and she, having espied her mothers ring lying on the board, slipped it on her finger and cried out, "See my father, how well my mothers ring fits me!" And the prince, when he saw what she had done, assented. But not long after this the soul of Tebaldo was assailed by a strange and diabolical temptation to take to wife his daughter Doralice, and for many days he lived tossed about between yea and nay. At last, overcome by the strength of this devilish intent, and fired by the beauty of the maiden, he one day called her to him and said, "Doralice, my daughter, while your mother was yet alive, but fast nearing the end of her days, she besought me never to take to wife any woman whose finger would not fit the ring she herself always wore in her lifetime, and I swore by my head that I would observe this last request of hers. Wherefore, when I felt the time was come for me to wed anew, I made trial of many maidens, but not one could I find who could wear your mothers ring, except yourself. Therefore I have decided to take you for my wife, for thus I shall satisfy my own desire without violating the promise I made to your mother." Doralice, who was as pure as she was beautiful, when she listened to the evil designs of her wicked father, was deeply troubled in her heart; but, taking heed of his vile and abominable lust, and fearing the effects of his rage, she made no answer and went out of his presence with an untroubled face. As there was no one whom she could trust so well as her old nurse, she repaired to her at once as the surest bulwark of her safety, to take counsel as to what she should do. The nurse, when she had heard the story of the execrable lust of this wicked father, spake words of comfort to Doralice, for she knew well the constancy and steadfast nature of the girl, and that she would be ready to endure any torment rather than accede to her fathers desire, and promised to aid her in keeping her virginity unsullied by such terrible disgrace.
