Systems and methods for ranking Web pages based on hyperlink information in a manner that is resistant to nepotistic links are provided. In one embodiment, a Web search service is provided for returning quality query results. The vulnerability of existing ranking algorithms, such as PageRank, to Web pages that are artificially generated for the sole purpose of inflating the score of target page(s) is addressed. Intuitively, it is recognized that it is less likely to reach a particular page on a Web server having many pages via a random jump than it is to reach a particular page on a Web server having few pages, which implies that the influence of such a page upon another page by linking to, or endorsing, the other page is diminished. Thus, in various non-limiting embodiments, each Web server, not each Web page, is assigned a guaranteed minimum score. This minimum score assigned to a server can then be divided among all the pages on that Web server.

A method for manufacturing a self aligned narrow structure over a wider structure based on mask trimming. A method for manufacturing a memory device comprises forming an electrode layer on a substrate which comprises circuitry made using front-end-of-line procedures. The electrode layer includes a first electrode and a second electrode, and an insulating member between the first and second electrodes for each phase change memory cell to be formed. A patch of memory material is formed on the top surface of the electrode layer across the insulating member for each memory cell to be formed. The patch and the first and second electrodes are formed using a self-aligned process based on mask trimming.

The present invention proposes methodologies, a system and a secure spontaneous collaboration framework along with a suitable application and services suite for enabling new paradigm of social networking among users of handheld devices by bridging gab between infra-structure-based networks and mobile ad hoc networks. While supporting three different operating modes for the spontaneous collaboration that suits the user preference and network conditions, the proposed solutions hide the complexity of finding the right peer/device for spontaneous collaboration, self-organising the network to be formed on-demand, mitigating the security threat, being aware of user mobility for service continuity across wide variety of networks. Binding a given user to user's handheld device and specifying the number of applications/services enabling spontaneous collaborations that a given user is interested in are possible through user-profile creations. By taking a holistic view, the proposed solutions enable very practical, scalable, secure and economical spontaneous collaborations.

By providing contact plugs having a lower plug portion, formed on the basis of well-established tungsten-based technologies, and an upper plug portion, which may comprise a highly conductive material such as copper or a copper alloy, a significant increase in conductivity of the contact structure may be achieved. For this purpose, after the deposition of a first dielectric layer of the inter-layer stack, a planarization process may be performed so as to allow the formation of the lower plug portions on the basis of tungsten, while, after the deposition of the second dielectric layer, a corresponding copper-based technology may be used for forming the upper plug portions of significantly enhanced conductivity.

A method and system generates and compares fingerprints for videos in a video library. The video fingerprints provide a compact representation of the temporal locations of discontinuities in the video that can be used to quickly and efficiently identify video content. Discontinuities can be, for example, shot boundaries in the video frame sequence or silent points in the audio stream. Because the fingerprints are based on structural discontinuity characteristics rather than exact bit sequences, visual content of videos can be effectively compared even when there are small differences between the videos in compression factors, source resolutions, start and stop times, frame rates, and so on. Comparison of video fingerprints can be used, for example, to search for and remove copyright protected videos from a video library. Furthermore, duplicate videos can be detected and discarded in order to preserve storage space.

A time of day zoning control system for a heating, ventilating, and air conditioning system is provided. The system utilizes a programmable thermostat and a number of temperature sensors to control the HVAC system to regulate the temperature in a particular location within a dwelling or structure based on consumer preferences. The regulation control will utilize a temperature sensed by a particular temperature sensor at different times throughout the day to control the temperature in that zone to ensure occupant comfort. A single temperature sensor may be selected to control the HVAC system during these different periods, or multiple sensors may be utilized during the same period. When multiple sensors are used, a weighting factor may be used.

A method for determining one or more structure-function characteristics of a structure in a human or animal body from an image of the structure includes generating a structural model of a structure based on an image of the structure.

Methods and systems for performing measurements of semiconductor structures and materials based on scatterometry measurement data are presented. Scatterometry measurement data is used to generate an image of a material property of a measured structure based on the measured intensities of the detected diffraction orders. In some examples, a value of a parameter of interest is determined directly from the map of the material property of the measurement target. In some other examples, the image is compared to structural characteristics estimated by a geometric, model-based parametric inversion of the same measurement data. Discrepancies are used to update the geometric model of the measured structure and improve measurement performance. This enables a metrology system to converge on an accurate parametric measurement model when there are significant deviations between the actual shape of a manufactured structure subject to model-based measurement and the modeled shape of the structure.
