  • Deformation in the Presence of Fluids and Mineral Reactions

    Natural and experimental deformation of fault rocks show that fluid flow and mineral reactions are linked to fracturing in a nonlinear feedback relationship that potentially affects the displacement and stress histories of large faults. These interactions spawn instabilities that are expressed as episodic seismic events involving cataclasis, which alternate with slow, aseismic deformation involving pressure-solution creep, as well as healing and sealing by fluid-assisted mass transfer. This chapter focuses on the timescale of these processes during the earthquake cycle, with special emphasis on the evolution of rheological and transport properties of fault rock during the interseismic period. Fracturing weakens faults dramatically by enhancing the kinetics of pressure-solution creep and of mineral reactions. Therefore, during the postseismic period and initial part of the interseismic period, weakening is faster than fault strengthening by healing and sealing of fractures. During the interseismic period, mass transfer associated with fluid-assisted chemical reactions smoothes asperities on fault surfaces, heals fractures and enhances the formation of a foliation parallel to the fault plane, and decreases permeability. If advective fluid inflow is significant, this can increase pore-fluid pressure and reduce effective shear strength, at least locally within the fault. In the long term, however, the combined effect of fracturing, pressure-solution creep, and sealing is to restore the rheological and transport properties of the fault during the interseismic period, setting the stage for renewed stress build-up and seismicity. We demonstrate the salient characteristics of fluid-assisted fault weakening and strengthening with a one-dimensional model of an idealized fault zone undergoing simple shear at constant velocity. The model shows that the kinetics of the weakening a nd strengthening processes determine the relative rates of shear stress decrease and increase during the interseismic period. The kinetics of dissolution precipitation and mineral reactions are therefore expected to exert an important control on the recurrence time of earthquakes.

  • A Bottom-Up Mechanism for Behavior Selection in an Artificial Creature

    In this paper we propose a mechanism for motivational competition and selection of behavior. One important characteristic of this mechanism is that the selection of behavior is modelled as an emergent property of a parallel process. This in contrast with mechanisms for behavior selection and motivational competition proposed earlier, which are based on a hierarchical. preprogrammed control structure. We show that selection of behavior can be modeled in a bottom-up way using an activation/inhibition dynamics among the different behaviors that can be selected. There is no weighing up of behaviors in a cognitive manner and neither are hierarchical or bureaucratic structures imposed. The paper elaborates upon the results we obtained with simulated creatures based on this mechanism. It draws parallels between characteristics observed in animal behavior and characteristics demonstrated by our artificial creatures. Examples are: displacement behavior, opportunistic behavior, fatigue, selective attention, and so on.

  • Visual Pattern Recognition, Neural Networks, and Household Chores

    The visual field of each eye is split in half. Approximately half of the axons from each eye cross over so that the left hemisphere of the brain processes the right half of the visual fields while the right hemisphere processes the left half. The optic nerves lead to the lateral geniculate nuclei and then proceed to the primary visual (striate) cortex. Here, according to the research of Hubel and Wiesel, groups of neurons are organized into short lines that fire when an edge, corresponding to that particular orientation, enters the visual field. Half of the neurons process signals that originated in the left eye (L layers) and the other half process signals from the right eye (R layers); the Land R layers are interleaved. The visual image is thus dissected into many short edges, the first step in the hierarchical buildup of more complex geometrical shapes. All possible edge orientations are detected by a layer of simple (S) cells; these feed a layer of complex (C) cells which bestow invariance with respect to lateral displacement. A one-dimensional model is presented in which a to-element visual signal is analyzed by an S1C1 pair of layers feeding an S2C2 pair. The model looks at (1) a white strip gradually lowered over a black background; (2) a white bar moving downward; and (3) a white bar that expands until it covers the entire black background. Some rules for designing one-dimensional pattern-recognition models are derived. Self-organization of the cortex is considered. A scheme is presented by which one cell in a group of cells captures the input for itself and suppresses all of the other neurons. A somewhat more complicated neural network is examined as it goes through learning, organizing, and testing phases. Because the same techniques are common to real and artificial neural net works (ANNs), a section is devoted to ANNs. Associative memory, the task-assignment problem, and back propagation are considered. Various ?>household chores?> associated with vision are also discussed as follows: the constant jerky movements of the eye (saccadic motion) and compensation for it; control of the lens opening (pupillary reflex); distance accommodation; and binocular convergence.

  • Pumps

    The pumps are used to deliver energy to a fluid, which increases the discharge pressure or head of the pump. This pressure is then used to move the fluid from one point to another. There are three main types of pumps used in the power generation facility. These are the centrifugal pump, the axial flow pump, and the positive displacement pump. The amount of pressure or head that a pump must develop to deliver a certain amount of flow is determined by the system resistance to flow that the pump is connected to. To produce flow, the pump must first develop sufficient pressure to overcome the static pressure and frictional losses at the discharge of the pump that the system imposes on the pump. This is defined by the system resistance curve. Flow control for a positive displacement pump is almost always via variable speed control.
