The Buckling Restrained Braced Frame (BRBF) is used in steel structures as a lateral load resisting system for seismic events. In typical design procedure the impact of gravity loads acting on BRBFs is neglected and the beams and columns of the structure are designed to resist all gravity loads. In actuality BRBFs are supporting portions of gravity loads acting on the structure which may be changing the overall performance of BRBFs. The purpose of this study is to determine the impact of large gravity loads on BRBF performance. This is done using finite element analysis to test two different structures supporting large gravity loads. The first structure is a seven story structure consisting of different BRBF configurations; the second structure is a three story structure with all BRBFs in an eccentrically braced configuration. Each structure was modeled with applied ground motion simulations with and without gravity loads, and with gravity loads but no applied ground motion simulations. Results indicate that gravity loads have no significant impact on the overall performance of BRBFs for either structure.

This thesis presents an interface for effectively teleoperating robots that combines an ecological display of range and video information with quickening based on dead-reckoning prediction. This display is built by viewing range and video information from a virtual camera trailing the robot. This is rendered in 3-D by using standard hardware acceleration and 3-D graphics software. Our studies demonstrate that this interface improves performance for most people, including those that do not have much previous experience with robotics. These studies involved 32 test subjects in a simulated environment and 8 in the real world. Subjects were required to drive the robot through several mazes while remembering a sequence of items. People took less time using the ecological interface and experienced fewer collisions, with a much lower workload as measured by joystick entropy. People preferred the interface over a standard interface with side-by-side range and video information and no prediction. Participants tended to rate the interface as more learn-able and more intuitive; participants also felt more confident in the robot's expected behavior.

The Rijndael encryption algorithm has recently been published as the Advanced Encryption Standard (AES), a Federal Information Processing Standard, and is being accepted by developers and designers as the algorithm of choice where encryption is required. Java is becoming the language of choice for E-Business applications, many of which require cryptography. The performance of any Java application is dependent on the compiler and virtual machine used to compile and interpret. Prior research has provided performance information for the Rijndael algorithm in Java for specific virtual machines. This research includes the development of a Rijndael implementation in Java. Using Java system calls, the performance of the Rijndael implementation is measured across fifteen compilers and fourteen virtual machines. Through analysis of these benchmarks, the Java performance of the Rijndael algorithm across compilers and virtual machines is produced.
