20140318592 | ENHANCEMENT OF THERMOELECTRIC PROPERTIES THROUGH POLARIZATION ENGINEERING - A method for enhancement of thermoelectric properties through polarization engineering. Internal electric fields created within a material are used to spatially confine electrons for the purpose of enhancing thermoelectric properties. Electric fields can be induced within a material by the presence of bound charges at interfaces. A combination of spontaneous and piezoelectric polarization can induce this interfacial charge. The fields created by these bound charges have the effect of confining charge carriers near these interfaces. By confining charge carriers to a channel where scattering centers can be deliberately excluded the electron mobility can be enhanced, thus enhancing thermoelectric power factor. Simultaneously, phonons will not be affected by the fields and thus will be subject to the many scattering centers present in the majority of the structure. This allows for simultaneous enhancement of power factor and reduction of thermal conductivity, thus improving the thermoelectric figure of merit, ZT. This approach is also compatible with other strategies for reducing thermal conductivity, for example the inclusion of nanostructures. | 10-30-2014 |

20150088639 | Predicting User Interactions With Objects Associated With Advertisements On An Online System - Based on prior interactions associated with a user, an online system predicts an amount of interaction by the user with an object associated with an advertisement. Using the predicted amount of user interaction, the online system determines an expected value of presenting the advertisement to the user. The advertisement is ranked among other advertisements based on the expected values associated with the advertisements, and one or more advertisements are selected for presentation to the user based on the ranking. An advertisement may also specify a threshold amount of interaction with an associated object as targeting criteria, so the predicted amount of interaction with the object associated with the advertisement may determine if a user is eligible to be presented with the advertisement. | 03-26-2015 |

20150206179 | DYNAMICALLY ALLOCATING COMPUTING RESOURCES TO IDENTIFY ADVERTISEMENTS FOR PRESENTATION - An advertising system has limited computing resources to spend evaluating advertisements of advertisers to determine a “best” advertisement to serve to users of a social networking system. The computing resources are allocated (e.g., by varying the number of advertisements that are considered for presentation to a user) based on the neediness of the user and/or the advertiser on a per impression basis. The neediness of a user may be determined by grouping users into groups and determining a yield curve of expected revenue per computing resource used. Then, the revenue may be maximized across impression opportunities for multiple users. The neediness of an advertiser may be determined by biasing the selection of one advertiser's advertisements over another advertiser's advertisements based on an expected revenue, an expected number of interactions of the advertisement, or otherwise maximizing a satisfaction coefficient for the advertiser. | 07-23-2015 |

20110030552 | COMPRESSED AIR ENERGY STORAGE SYSTEM UTILIZING TWO-PHASE FLOW TO FACILITATE HEAT EXCHANGE - A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control. | 02-10-2011 |
