Automatic vehicle following for emergency lane change maneuvers
(Texas A&M University, 1998)
A lane change maneuver is one of the many appropriate responses to an emergency situation. This thesis proposes to design a combined controller for automatic vehicles for an emergency lane change (ELC) maneuver on an ...
An estimation algorithm for 3-D pose measurement using redundant ultrasonic sensors
(Texas A&M University, 1998)
Accurutely and economically measuring the 3-D position ics. and orientation (3-D Pose) of an object has many applications for automated equipment. Traditionally, this may require the desired accuracy. Previous research has ...
Sources of Error in Chilled and Hot Water Metering at Shared Sites: Differential Pressure Transmitters and Flowmeter Installation
(Texas A&M University, 1998)
The Energy Systems Lab at Texas A&M University monitors energy consumption through shared signals in twenty-two campus buildings under a contract with the University. A major part of this monitoring includes measuring ...
Lateral control of articulated vehicles for automated highway systems under uncertainty in vehicle parameters
(Texas A&M University, 1998)
Studied in this thesis is the formulation of lateral control algorithms for articulated vehicles performing a lane following maneuver on Automated Highway Systems (AHS). A steering control algorithm using the input/output ...
Rotordynamic instability: nonlinear modeling and analysis
(Texas A&M University, 1998)
A basic rotordynamic model is developed for an crographics. unbalanced rotor connected to a shaft modeled as a continuous beam. This model examines the effects of nonlinear dynamics strictly related to the rotor and shaft. ...
Drying characteristics of slot jet reattachment nozzle and comparison with a slot jet nozzle
(Texas A&M University, 1998)
Slot Jet Reattachment (SJR) nozzle is an extension of hics.the Radial Jet Reattachment (RJR) concept used to provide high heat and mass transfer while allowing for the control of flow exerted force on the reattachment ...
Planar visualization of phase objects using a focusing schlieren technique
(Texas A&M University, 1998)
A focusing schlieren technique has been designed and phics. constructed to examine planar images of optically thin phase objects including high-speed gas jets and flames. The conventional schlieren technique is a highly ...
Commanding lateral acceleration: a natural paradigm for automobile steering
(Texas A&M University, 1998)
This thesis describes a joystick automobile steering phics. controller which allows the driver to command the lateral acceleration of the vehicle directly, as opposed to controlling the front tire angle. The purpose of the ...
Experimental thermal conductivity and contact conductance of graphite composites
(Texas A&M University, 1998)
Graphite fiber organic matrix composites were reviewed ics. for potential heat sink applications in the electronics packaging determined the effective transverse and longitudinal thermal industry. This experimental ...
Genetic Algorithms applications to optimization and system identification
(Texas A&M University, 1998)
Genetic Algorithms (GA) are very different from the traditional optimization techniques. GA is a new generation of artificial intelligence and its principles mimic the behavior of the biologic genes in the natural world. ...
