Abstract: Crack-free powder-based, near net shaped parts are fabricated using a die assembly and cold isostatic pressing. Soft materials are introduced on both sides of die components in order to balance compression loads applied to the die component, and thereby avoid deformation of the die component.

Abstract: An apparatus and system for providing a secure user interface restricting the access of users to selected functions, files, and communications by implementing a customizable secure graphical user interface. The degree to which the user's access is restricted may depended on levels of authorization granted to the user. The secure user interface may be implemented on a device and employed to aid a user in executing diagnostic, service, maintenance, and data gathering tasks. The secure computing device may be connectable to other computing devices of like of different kind. The secure computing device may provide security against non-authorized users by requiring user identification and disabling the device when proper identification is not given or the device is deemed missing.

Abstract: A method of cavitation peening a workpiece is provided. The method includes discharging a flow of fluid towards the workpiece at a pressure and a flow rate that facilitates forming a plurality of cavitation bubbles, monitoring a feedback parameter associated with the plurality of cavitation bubbles, and determining a peening intensity of the plurality of cavitation bubbles based at least partially on a value of the feedback parameter.

Abstract: An aircraft has a fuselage, a lifting free wing, and a nose section. The fuselage has a front end, a rear end, and a longitudinal axis. The lifting free wing is pivotally connected to the fuselage with a pivot. The nose section is pivotally mounted on the front end of the fuselage, and includes a pair of engines, and a pair of counter-rotating propellers. A canard free wing is pivotally connected to the nose section with a pivot. A pair of vertical stabilizers are mounted on the rear end of the fuselage and each includes a rudder and a pair of landing gear.

Abstract: A primary-secondary pumping system for HVAC systems wherein the common pipe is configured so that there is at least a 4 ft pressure drop across the length of the common pipe and that all thermal plants see the same temperature of water entering the thermal plants and that return water sees the pressure drop of the common pipe before it sees the chilled (or heated) water leaving the thermal plant and the suction of the secondary pumps.
