Human-automation collaboration in occluded trajectory smoothing
… should be engaged in a Ballistic Missile Defense System (BMDS) scenario involves a number of complex issues. The system is large and the timelines may be on the order of a few minutes, which drives designers to highly automate these systems. On the other hand, the critical nature of BMD engagement …

Experimental and numerical quantification of EV and PHEV battery pack thermal isolation strategies
… into an electrified vehicle’s energy storage system by design. Temperature changes within the cells are to be minimized over the typical 24 hour daily cycle when exposed to extreme ambient climates. Productionized thermal management solutions take the approach of increasing heat transfer …

An enhanced volume integral equation method and augmented equivalence principle algorithm for low frequency problems
… present equivalence principle algorithm (EPA) is augmented by introducing charge densities as extra unknowns. This helps to separate the vector potential term and scalar potential term and avoid the imbalance at low frequencies. The current continuity constraint is enforced in both the scattering …

Least Square Methods for Solving Systems of Inequalities With Application to an Assignment Problem
… Secondly, the research addresses solving systems of inequalities (and equalities) in a least square sense. The specific assignment problem has piece-wise linear additive separable server cost functions, which are continuous everywhere except at zero, the point of discontinuity for the …

Machine tool chatter suppression using spindle speed variation
… and stability of nonlinear delay gyroscopic systems with periodically varying delay. The aim is to demonstrate that greater depths of cut may be achieved in a boring process (2 DOF) when the speed of the spindle is modulated sinusoidally instead of being kept constant. Since the variation of …

Parameter estimation for single-phase induction motor from transient measurements
… The NR-based algorithm iteratively solves a system of non-linear equations involving the parameter values of leakage inductances, magnetizing inductance, and rotor resistance. Selected parameters are further tuned based on a non-linear least squares (NLS) formulation that minimizes the …

Contributions to model following control theory
… laws developed. The error dynamics of such systems are analyzed with respect to stability of the error. The effects on the error dynamics of measurement errors and parameter variations are also analyzed, and it is seen that the perfect model following control problem is reduced to that of an …

Integral Perception in Augmented Reality
Augmented reality, the superimposing of graphics or text onto an actual visual scene, is intended to enhance a user's understanding of the real world. This research examines the perceptual, cognitive, and human factors implications of combining integrally designed computer-generated imagery with …

On a Cartesian cut-cell methodology for simulating atmospheric ice accretion on aircraft
… interface. The initial chapter presents an augmented air and droplet model which tracks droplet temperatures thereby producing more accurate heat fluxes for the phase transition calculation. Firstly, we validate our novel model for common ice accretion test cases and find excellent agreement …

Networked Predictive Control Systems: Control Scheme and Robust Stability
… is a new research method for Networked Control Systems (NCS), which is able to handle network-induced problems such as time-delay, data dropouts, packets disorders, etc. while stabilizing the closed-loop system. This work is an extension and complement of networked predictive control …

Reliable design of interdependent service facility systems under correlated disruption risks
… at the center of planning many infrastructure systems. In many practice, public agencies (e.g., governments) and private companies (e.g., retailers) need to locate facilities to serve spatially distributed demands. For example, governments locate public facilities, e.g., hospitals, schools, …
