Abstract: A method (300) of fabricating an object by additive manufacturing comprises providing (310) a layer of polymeric material (100), said polymeric material (100) being in particulate form, and comprising linear polymer chains, selectively depositing (320) a reactive liquid (200) onto the layer of particulate polymeric material (100), said reactive liquid (200) comprising reactive units (210a) which are monomeric units, linear oligomeric units, linear polymeric units, or combinations thereof, wherein said reactive units (210a) have two or fewer reactive groups, and allowing (330) linear polymeric chains in said layer of polymeric material (100) to react with reactive units in said reactive liquid (200) so as to form extended polymeric chains that are linear, so as to provide a shaped layer of linear polymer. These steps (310, 320, 330) are repeated as required to form the object from successive shaped layers of linear polymer.

Abstract: The systems and methods for streamlining data compilation and report generation include storing one or more academic categories having one or more performance indicators in an electronic database, each performance indicator forming part of a sentence. A metric associated with each performance indicator forms another part of the sentence. The academic categories are displayed on a screen with the performance indicators and metrics associated therewith for selection by a user. Student information is then received and processed along with the selections of the academic categories, the performance indicators and the metrics from an interactive computer medium over a communication network. The received performance indicators are combined with each of the received metrics, and based on the student information, to create at least one complete sentence presentable in a student report measuring the academic performance of a student for one or more academic categories.

Abstract: Techniques for determining a problem location or otherwise characterizing a network comprising a plurality of processing elements, including at least one processing element associated with performance of a packet encapsulation operation of an encapsulation protocol. The packet encapsulation operation is performed on a test packet to generate an encapsulated packet, the test packet having a time to live (TTL) value and an identifier. In conjunction with performance of the packet encapsulation operation, the TTL value and the identifier of the test packet are copied to a header of the encapsulated packet. The encapsulated packet is transmitted, and a determination is made as to whether a reply packet has been received responsive to transmission of the encapsulated packet. The reply packet, if any, is processed to obtain information utilizable in determining the problem location or otherwise characterizing the network.

Abstract: A power converter including a star converter module network and a star resistive network. A feedback network monitors the voltage difference between the nodes of the star converter module network and the star resistive network, and provides a signal for each phase of an AC supply corresponding to the voltage difference. An output sensing means senses the output voltage across output terminals and produces a demand signal based on a comparison of the output voltage with a required value. A controller produces a control signal based upon this comparison for each phase, and the control signal is used to control a corresponding converter module. Applications include power converters for supplying an isolated supply from a multi-phase main supply not having a neutral connection.
