Abstract: A system and method for controlling blisters. The method begins by mixing the ingredients to form a dough with a moisture content between about 35% and 60%. The dough is sheeted and cut. Thereafter, the dough is pre-heated to reduce the moisture content to between about 10% and about 45%. The preforms are then docked and dehydrated. The docking system, in one embodiment, has a backing plate and a docking device with at least two docking pins of varying lengths. The docking device is adjustable relative to the backing plate. The system also has a removing plate which removes preforms from the docking pins.

The invention also provides a process of activating an oligomerization catalyst to be used to produce an oligomeric product from at least one olefinic compound.

Abstract: The invention presents a dual-mode hybrid high occupancy capacity vehicle (HHOCV) with a novel electrical energy and power storage application, electrical energy and power source and charging system in conjunction with additional methods to maximize the energy and rate of use such that the overall system is far superior to multiple personal transportation vehicles and roadway based catenary mass transit systems, including, but not limited to petroleum-only fueled high occupancy capacity vehicles. The HHOCV exhibits a novel battery charging system by taking advantage of existing track/trolley/catenary facilities for electrically charging its electrical storage media at a high energy rate so as to minimize disruption of such charging services, and is not confined by physical boundaries or limitations and may travel off the power source to the existing common roadways returning only to be recharged.

Abstract: In particular embodiments, a method comprising, by one or more computing devices, identifying, at a client device, one or more objects or references to the one or more objects embedded in a structured document displayed to a first user, accessing a social graph to determine if one or more second users having an association with the first user have accessed any of the one or more identified objects, and modifying, for at least one of the one or more identified objects, the structured document displayed to the first user to indicate that the at least one or more identified objects has been accessed by one or more second users.

Abstract: A method and a device useful for identifying or detecting the presence of a material of interest, such as an explosive or a biological contaminant, in a sample is presented herein. The sample is illuminated with electromagnetic radiation at a predetermined set of wavelengths. An example of an illumination source includes a quantum cascade laser (QCL). The radiation reflects from a sample and is detected at pixels of a detector. Examples of the detectors include digital focal plane array (DFPA) cameras. Intensity of the reflected radiation is measured at each illumination wavelength. The pixels can be configured to add weighted intensities of the reflected radiation, the weights of the intensities being based on a predicted optical response value for the sample at the wavelengths of the first set and the second set of wavelengths. Based on the sum of weighted intensities of the reflected radiation, the likelihood that the material is present within the sample is determined.

Abstract: Embodiments include a method, system and computer program product for automating individual learner course selection. The method includes accessing, by a computer processor, course descriptions for a plurality of variants of a course. The course descriptions include course variant characteristics and course variant titles. The course variant characteristics define target audiences for each of the variants of the course. Information about a user, including user characteristics is received. The course variant characteristics are compared to the user characteristics. Based on the comparing, a specificity value is calculated for each of the variants of the course. The specificity value indicates a degree of match between the user and a target audience of the variant of the course. A variant of the course is selected for the user based on the specificity values, and the course title of the selected variant of the course is output.

Abstract: A system may receive orders from disparate sources, each order specifying at least one item located in a physical storage area divided into subareas. The orders may be prioritized for desired processing sequence. The system may determine, beginning with high priority orders specifying at least two items for each order, a virtual order footprint that represents all of the subareas corresponding to the items in the order and form a plurality of virtual potential pick batches, each virtual potential pick batch comprising orders in a unique virtual order footprint. When a configurable limit is reached, the number of orders in each virtual potential pick batch is determined. The order counts are a factor in determining which of the virtual potential pick batches are to be released for processing by available work resources. All other non-selected virtual potential pick batches are deconstructed awaiting the future availability of work resources.
