Abstract: In one embodiment, data records associated with attributes are received. A check is made to determine whether the data records are greater than a maximum data record limit of a graph. Further, when the maximum number of data records in the bin is less than or equal to the maximum data record limit of the graph, the data records are retrieved and presented in the graph. When the data records are greater than the maximum data record limit of the graph, the data records are grouped into bins based on initial bin sizes corresponding to the plurality of attributes. Furthermore, weighted densities of the bins are determined using a maximum number of data records associated with a bin and a maximum data record limit of the bin. Further, the graph is rendered to present the weighted densities of the bins using a randomization technique to analyze the data records.

Abstract: A method for inactivating medically important Gram-positive bacteria including Methicillin-resistant Staphylococcus aureus (MRSA), Coagulase-Negative Staphylococcus (CONS), Streptococcus, Enterococcus and Clostridium species, comprising exposure to visible light, and in particular light within the wavelength range 400-500 nm.

Abstract: An iterative approach to detect outliers may automatically detect outliers in a data set. The iterative approach may include calculating a mean and an average deviation for a list. The iterative approach may further include calculating the deviations of values of a list if the average deviation is not zero. Any values where the calculated deviation of the point or value is greater than the mean may be selected. The selected points may be set as a second list. The second list may be used by the iterative approach until no points are selected for the second list. The previous list is the set of outliers from the data set.

Abstract: An optical absorption gas sensor includes a radiation source, detector and radiation guide which has a rectangular cross section and curves around a side of the cross section. Locating elements locate a support element relative to the radiation guide to align the radiation source and detector with the guide. Radiation from the reference radiation source may be transmitted through a transparent measurement radiation source. Radiation from a reference radiation source may be directed around the measurement reference source. A light emitting diode may generate radiation which is detected by a photodiode and the photodiode may be driven to generate radiation having a different emission spectrum detectable using the light emitting diode, in another operating mode. Two or more abutting L-shaped radiation guide portions may form the radiation guide.

The social networking system aggregates the first plurality of user-submitted content items into a bundled event memory, and transmits the bundled event memory to at least some of a plurality of user devices to be presented to at least some of the plurality of users, wherein the plurality of users utilize the plurality of user devices to communicate with the social networking system.

Abstract: Exemplary methods, apparatuses, and systems display selectable partners to facilitate a financial contribution from a user, receive user selection of one of the partners and an amount of the financial contribution, receive partner feedback to demonstrate an impact of the financial contribution, and display the feedback to the user. The feedback includes a photograph taken of a beneficiary of the financial contribution upon receiving benefit of the financial contribution. The partner submits the feedback to an organizer for review and the organizer approves and provides the feedback to the user.

Abstract: A social networking system requests a customizable product from a retailer. The retailer accesses social information associated with one or more additional users connected to the social networking system users and generates recommendations for options to customize the customizable product based on the social information associated with the additional users. When the social networking system orders a customizable product using one of the recommended options, the social networking system is notified and generates a story describing the purchase that is communicated to the additional users of the social networking system.

Abstract: A social networking system user may request physical prints of digital photographs stored in connection with the user's user profile on the social networking system. The physical prints are generated by a photograph developer, such as a retail store, and retrieved by the user. The user may request the physical prints from an application executing on a user device that allows the user to identify social context information associated with a digital photograph for inclusion on the physical print. The social networking system may notify users connected to the user and/or to the digital image of the physical print generation.

Abstract: An optical absorption gas sensor has an LED light source and a photodiode light detector, a temperature measuring device for measuring the LED temperature and a temperature measuring device for measuring the photodiode temperature. The sensor is calibrated by measuring the response of photodiode current at zero analyte gas concentration and at a reference analyte gas concentration. From these measurement, calibration data taking into account the effect of photodiode temperature on the sensitivity of the photodiode and, independently, the effect of changes in the spectrum of light output by the LED on the light detected by the photodiode with LED temperature can be obtained. Calibration data is written to memory in the gas sensor and in operation of the gas sensor, the output is compensated for both LED and photodiode temperature. The LED and photodiode can therefore be relatively far apart and operate at significantly different temperatures allowing greater freedom of optical pathway design.
