Abstract: Devices, circuits, and methods for fabricating circuits. A device having ambipolar characteristics includes a semiconductor layer and multiple gates, a source contact, and a drain contact coupled to the semiconductor layer. One channel may have elections as the majority charge carrier and may be formed proximate to one of the gates. Another channel may have holes as the majority charge carrier and be formed proximate another gate. Each of the channels is generally parallel to the other and couples the source contact to the drain contact. The device may be optimized by adjusting the work-functions in one or more of source and drain contacts or gates to compensate for differences in the effective masses of the majority carriers in each of the channels. The ambipolar nature of the devices allows logic circuits to be fabricated using one or two of the devices.

Abstract: A fluid processing system and method of processing a fluid includes a tank having an outer wall, a heating element, and an insulating element. The heating element is situated within the tank and includes a first electrode and a second electrode. The insulating element is positioned between the first electrode and the second electrode. As such, powering the heating element directs an electric current through the fluid within the tank for heating the fluid, while the insulating element provides electrical and thermal insulation to the outer wall of the tank.

Abstract: A passive variable negative stiffness device (passive VNSD) configured to facilitate a transition to zero stiffness by using elastic devices (e.g., springs) combined with translating and rotating components. An exemplary embodiment of a passive VNSD may comprise at least one pretensioned and/or precompressed elastic device to produce the desired force-displacement profiles. For instance, an exemplary embodiment of a passive VNSD may be adapted to produce force-displacement profiles that transition from zero stiffness, to negative stiffness, and then to positive stiffness (ZNP) and from zero stiffness, to negative stiffness, and then back to zero stiffness (ZNZ).

Abstract: Methods of patient-specific modeling of the mechanical properties of bone and related systems. The methods include obtaining a bending stiffness (K) of a bone specimen non-invasively and non-destructively in a dynamic 3-point bending test, creating a mathematical mechanical model of the bone specimen, assigning an elastic modulus (E) to the bone specimen of the mathematical mechanical model, determining the flexural rigidity of the bone specimen from simulating the mathematical mechanical model, determining a discrepancy between the flexural rigidity of the bone specimen from the simulated mechanical model and based on the obtained K, adjusting the elastic modulus of the simulated mechanical model to minimize the discrepancy, adjusting the elastic modulus until an optimized elastic modulus is determined where the discrepancy is reduced below a predetermined threshold, and applying the optimized elastic modulus to the simulated mechanical model to determine a strength of the bone.

Abstract: A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator includes an array of vertical wet cords stretched within a duct. The cords are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves. A plurality of these sieves are arranged to define a plurality of gaps, through which the exhaust flows. The sieves and thus the cords are space so that a vortex from a first cord affects an adjacent cord and subsequently cord. The particles are then absorbed in liquid, which can be passed through a heat exchanger filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.
Abstract: A resetting semi-passive stiffness damper (RSPSD) triggering assembly and a RSPSD and method of use for damping movement of an object. Exemplary embodiments of a RSPSD triggering assembly include, for example, a rotatable disc and a spring-loaded lever arranged between the disc and a slotted channel. A sensor is provided and communicates with a bypass valve on the cylinder. A change in the direction of movement of the disc causes reciprocation of the lever in the channel, which causes the sensor to send open and close signals to the bypass valve. In some embodiments, a single disc may be replaced with two interacting discs. A RSPSD equipped with such a triggering assembly is usable to damp movement of an object of interest.
