Abstract: In one embodiment, a computing device receives a request from a mobile device of a user for an image. The computing device determines whether the user is associated with a preferred orientation for viewing an image. The preferred orientation is determined based on the user's usage patterns with respect to a particular application of the mobile device, or to the user's interactions with a social-networking system. If the user is associated with a preferred orientation, the image is adjusted to have the preferred orientation and to match display capabilities of the mobile device sending the request. The adjusted image is sent to the mobile device for display.

Abstract: The present invention discloses the fabrication and application of a shape memory polymer possessing transesterification-induced permanent reshaping. The ester-containing crosslinked polymer is obtained by crosslinking ester bearing polymer precursors or by reaction of monomers which yield ester bonds. The transition temperature falls between 20-150° C. The reshaping temperature is tuned by catalyst amount and should be 20° C. above the transition temperature. The breakthrough of the present invention lies in integrating shape memory effect and plastic deformation into the same polymer and triggering the respective function at different occasions. The permanent shape of as synthesized polymer could be modified arbitrarily and cumulatively. Therefore, the hierarchical structure which could not otherwise be obtained due to the limit of mold fabrication process should expand the practical application of SMPs.

Abstract: Aspects of the disclosure generally provide a heat engine system and a method for regulating a pressure and an amount of a working fluid in a working fluid circuit during a thermodynamic cycle. A mass management system may be employed to regulate the working fluid circulating throughout the working fluid circuit. The mass management systems may have a mass control tank fluidly coupled to the working fluid circuit at one or more strategically-located tie-in points. A heat exchanger coil may be used in conjunction with the mass control tank to regulate the temperature of the fluid within the mass control tank, and thereby determine whether working fluid is either extracted from or injected into the working fluid circuit. Regulating the pressure and amount of working fluid in the working fluid circuit selectively increases or decreases the suction pressure of the pump to increase system efficiency.
