Research Underway: Bangarang Data Entry Program ~ Users' Manual
RU: Bangarang 1.0 Users Manual Keen 2013 Research Underway: Bangarang Data Entry Program ~ Users’ Manual Developed by Eric Keen Scripps Institution of Oceanography Summer 2013 [email protected] CONTENTS_________________________________________________________________________________________ Introduction ………………………………………. 1 Where to Download………………………………. 1 Getting Started……………………………………. 1 Output: Overview………………………………… 3 Output: Standard Fields……………………....... 4 Output: Event Details ………………………….. 5 Appendix 1: Example output………………........ 24 Appendix 2: RUB Abbreviations……………….. 25 INTRODUCTION____________________________________________________________________________________ RU Bangarang (RUB) is a data entry program designed specifically for my dissertation work in the northern Great Bear Fjordland. It is designed to be an easily viewed, intuitive, button-based way of entering observations while letting the computer take care of associating each entry with the necessary but intensive logistical data (time, gps coordinates, current conditions, observers on board, effort status, etc.). The forms are designed to be navigated by using the mouse, using the tab key, or using the touch screen. It is also designed to output these data in a single file that can serve as both a raw record of the day's work and a single source from which to draw certain types of data (e.g. locations of hydrophone recordings and the locations of sighted whales). These, at least, were my intentions. The program was written in Visual Basic 2010 Express and published as a stand-alone executable file (.exe) for Windows. The program outputs text files to a folder it creates on the C directory of your computer. In addition to making this program available to others, I have provided the project files for the program, as well as my R scripts for analyzing the output text files, on my website. -
Robot Swarm Based on Ant Foraging Hypothesis with Adaptive Lèvy Flights
Robot Swarm based on Ant Foraging Hypothesis with Adaptive Lèvy Flights A thesis submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements of the degree of Master of Science in the Department of Mechanical and Materials Engineering of the College of Engineering and Applied Sciences by Aditya Milind Deshpande B.E. University of Pune August 2014 Committee Chair: Dr. Manish Kumar, Ph.D. Abstract Robot Swarm based on Ant Foraging Hypothesis with Adaptive Levy´ Flights by Aditya Milind Deshpande Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science Degree in Department of Mechanical and Materials Engineering University of Cincinnati June 2017 Design of robot swarms inspired by self-organization in social insect groups is currently an active research area with a diverse portfolio of potential applications. This thesis is focused on the development of control laws for swarm of robots inspired by ant foraging. Particularly, this work presents control laws for efficient area coverage by a robot swarm in a 2D spatial domain, inspired by the unique dynamical characteristics of ant foraging. The novel idea pursued in the effort is that dynamic, adaptive switching between Brownian motion and Levy´ flight in the stochastic component of the search increases the efficiency of the search and area coverage. The study is motivated by behaviors of certain biological studies who exhibit searching patterns modeled using Levy´ flight. Influence of different pheromone (the virtual chemotactic agent that drives the foraging) threshold values for switching between Levy´ flights and Brownian motion is studied using two performance metrics - area coverage and visit entropy. -

The longer bait ball stays together, the greater the chance that jack crevalle and tarpon will move in around the edges. Bull and blacktip sharks will follow the jack crevalle. If the bait ball is moving north or south and in and out of casting range, the feeding frenzy is relatively fresh. As the bait wears down, it starts moving in a cir- cular pattern and indicates the frenzy has gone on for some time.

ANIMATING PREDATOR AND PREY FISH INTERACTIONS by SAHITHI PODILA Under the Direction of Ying Zhu, PhD ABSTRACT Schooling behavior is one of the most salient social and group activities among fish. They form schools for social reasons like foraging, mating and escaping from predators. Animating a school of fish is difficult because they are large in number, often swim in distinctive patterns that is they take the shape of long thin lines, squares, ovals or amoeboid and exhibit complex coordinated patterns especially when they are attacked by a predator. Previous work in computer graphics has not provided satisfactory models to simulate the many distinctive interactions between a school of prey fish and their predator, how does a predator pick its target? and how does a school of fish react to such attacks? This dissertation presents a method to simulate interactions between prey fish and predator fish in the 3D world based on the biological research findings. -
