Study Notes
Computer Science and Computational Science
- Computer science studies algorithms, data structures, programming languages, and software development.
- Focus areas include artificial intelligence, machine learning, computer graphics, computer networks, and databases.
- Computational science applies computational methods to solve complex problems in scientific and engineering domains.
- Techniques in computational science involve modeling, simulating, and analyzing various phenomena in fields like physics, chemistry, biology, and engineering.
System Modelling and Simulation
- Numerical weather prediction, evolving since the 1960s, significantly improved forecasting accuracy.
- The Weather Research and Forecasting (WRF) Model was introduced in 2000, enhancing weather simulation models.
- Mathematical modeling has notably advanced our understanding of HIV pathogenesis between 2000-2002.
- The Institute for Environmental Modeling at the University of Tennessee utilizes computational ecology for Everglades management.
Applications of Computational Modeling
- In physics, simulations can study particles in plasma, the motion of celestial bodies, and material properties.
- Chemistry employs computational modeling to predict molecular properties and chemical reactions, aiding in new material design.
- Biology utilizes modeling for simulating cell behavior, protein structure prediction, and ecological dynamics.
- Engineering applies computational techniques for mechanical systems design, structural load predictions, and electrical circuit performance simulation.
- In finance, modeling helps predict stock prices, assess investment risks, and analyze market behaviors.
Modeling Process Steps
- Key process includes verifying and interpreting solutions to ensure accuracy and reliability in simulations.
Physically-Based Modeling
- Maps natural phenomena into computer simulations using mathematical equations.
- Provides numerical solutions for these equations, enhancing accuracy and efficiency.
- Approximation techniques are used to simplify complex mathematical models.
Simulation Challenges and Issues
- Realism in simulations, evaluation, and scenario specificity present ongoing challenges in physically-based modeling.
- Visualization aims for recognizable and useful images, with ideal goals focused on achieving photorealism.
Human Factors in Virtual Reality
- Depth perception relies on both monocular (one eye) and binocular (two eyes) cues.
- Monocular cues include motion parallax, where closer objects appear to move faster than distant ones, and linear perspective, where parallel lines converge at a horizon.
- Binocular cues involve convergence, where eye movement helps gauge an object’s distance, and stereopsis, responsible for the perception of depth.
The Human Eye and Perception
- The human eye has a total power of 60 diopters, with the lens contributing 20 diopters.
- Accommodation adjusts focus on objects at varying distances, influenced by vergence movement of the eyes.
Sound Localization
- Localization of sound sources uses three main mechanisms: interaural time difference (ITD), interaural level difference (ILD), and head-related transfer function (HRTF).
- ITD assesses the time difference in sound reaching each ear, while ILD measures variations in sound pressure levels between ears. HRTF considers how an individual's ear shape affects sound intensity and localization.
