Abstract: A student collects articles for a educational project having a topic. Analytical measures for the articles are determined in relation to the topic of the educational project. The analytical measures can include a relevance of the articles collected by the student to the topic. The analytical measures can include a coverage of how well the articles collected by the student cover the topic. The analytical measures can include a uniqueness of the articles collected by the student in comparison to one another.

Abstract: In a computerized method of visualizing features of messages communicated between a first user and a plurality of other users, a topic is identified and a visualization based upon messages containing at least one of the topic and a resource related to the topic is created. More particularly, the visualization is created to include at least one of user graphical representations and message graphical representations, and a resource graphical representation, such that, a user may easily identify features of the messages.

Abstract: A method and system thereof for reducing the energy consumed when decoding an encoded and synchronized multimedia data stream, wherein the data stream is non-preemptable and subject to precedence constraints. In a client-server environment, the server delivers to the client the stream for decoding. The client has a processor operating on a discrete variable-voltage power supply. Prior to transmitting the stream to the client, the server produces an execution schedule according to the precedence constraints. The server also assigns a voltage setting for each task in the schedule, wherein each task decodes a frame in the stream without preemption. The server transmits the execution schedule and voltage settings to the client with the encoded data stream. The schedule and voltage settings reduce energy consumption by the client while satisfying multimedia timing constraints.
