Automated radio network design using ant colony optimization: Author: Sharkey, Jeffrey Allen; Date: 2008-05-15; Program: Computer Science; Abstract: Radio networks can provide reliable communication for rural intelligent transportation systems (ITS). Engineers manually design these radio networks by selecting tower locations and equipment while meeting a series of constraints such as coverage, bandwidth, maximum delay, and redundancy, all while minimizing network cost. As network size and constraints grow, the design process can quickly become overwhelming. In this thesis we model the network design problem (NDP) as a generalized Steiner tree-star (GSTS) problem. Any solution to the minimum Steiner tree (MST) problem on a constructed GSTS ...; Download File | View full details

Men's Stereotypes of Women in Management: Are Women Aware of How They are Stereotyped?: Author: Crawford, Kevin Charles; Date: 2006-05-15; Program: Applied Psychology; Abstract: It is commonly thought that men and women differ in the extent or frequency to which each exhibits various traits-especially traits that are frequently perceived to be more agentic and stereotypical of males (e.g., aggressive and forceful) or more communal and stereotypical of females (e.g., interpersonally sensitive and sympathetic). Further, stereotypes frequently influence behaviors, with many real-world consequences, not the least of which are those often manifested in the disparate treatment of men and women in the workplace.
