Age, Growth, And Simulation Modeling To Characterize Fish Populations At Two Reservoirs In South-Central Kansas, Brian Serpan Nov 2014

Age, Growth, And Simulation Modeling To Characterize Fish Populations At Two Reservoirs In South-Central Kansas, Brian Serpan

Master's Theses

Several fish populations in Kansas are heavily exploited. To obtain insight into the response of fish populations to management actions, fisheries biologists must obtain as much information as possible with limited resources. To address these challenges, biologists often use age and growth information to understand the age structure of the populations, estimate recruitment and mortality, and gain insight into environmental and genetic factors influencing growth. In addition, age and growth data are used to generate yield-per-recruit models, which allow biologists to extrapolate population trends and make broad predictions about population responses to different management actions.

Smarticles: A Method For Identifying And Correcting Instability And Error Caused By Explicit Integration Techniques In Physically Based Simulations, Susan Aileen Marano

Master's Theses

Using an explicit integration method in physically based animations has many advantages including conceptual and computational simplicity, however, it re- quires small time steps to ensure low numerical instability. Simulations with large numbers of individually interacting components such as cloth, hair, and fluid models, are limited by the sections of particles most susceptible to error. This results in the need for smaller time steps than required for the majority of the system. These sections can be diverse and dynamic, quickly changing in size and location based on forces in the system. Identifying and handling these trou- blesome sections could allow …
