Quantitative Risk Assessment (QRA) is a methodology used to organize and analyze scientific information to estimate the probability and severity of an adverse event. Applied to microbial food safety, the methodology can also help to identify those stages in the manufacture, distribution, handling, and consumption of foods that contribute to an increased(More)
— This paper presents a comparison of receding horizon and artificial neural network controllers for the modeling of human driver behavior during coupled lateral-longitudinal maneuvers. Driver models have been previously developed using control theoretic approaches, such as model predictive control, also known as receding horizon control, and have been(More)
The low-level RF system for PEP-II is a modular design housed in a VXI environment and supported by EPICS. All signal processing and control is done at baseband using in-phase and quadrature (IQ) techniques. Remotely configurable RF feedback loops are used to control coupled-bunch instabilities driven by the accelerating mode of the RF cavities. A(More)
A modal decomposition is used to study the coupled longitudinal motion of electron bunches in a storage ring. The decomposition allows the simultaneous measurement o f g r o wth rates and feedback induced damping rates of all unstable beam modes via a time-domain transient technique. The damping rates of naturally stable modes are measured via a related(More)
The use of cryotherapy for the treatment of some unresectable liver tumours has been clearly established as a therapeutic option. Intra-operative ultrasound has enhanced the process by enabling the surgeon to identify hepatic lesions and to allow visualisation of the freezing process to ensure that the cryolesion will include the tumour mass. The purpose of(More)
The Gap Voltage Feed-Forward (GVFF) Module produces adaptively generated inphase (I) and quadrature (Q) reference signals for a single RF station. This module measures the periodic (1-turn) beam induced cavity transients caused by the presence of an ion clearing gap in the beam. A reference waveform is generated to minimize the direct feedback error signal(More)
This paper discusses the research, design and implementation issues associated with an economical self-balancing "inverted-pendulum" autonomous robot. Driven by two independent wheels, the inspiration for this configuration stems from the control engineering challenge of balancing the inverted pendulum. An autonomous vehicle of this kind can only be(More)
In contrast to the phorbol ester oxidative response, which only develops during dimethylsulphoxide (DMSO)-induced differentiation of the human leukemic myeloblast HL-60 cell-line, the endotoxin response was observed in undifferentiated and differentiated cells. The Ca2+ response to endotoxin, detected in both differentiated and undifferentiated HL-60 cells,(More)
