    Abstract: The iron and steel industry has a history of environmental consciousness and efforts are continually made to reduce energy consumption and CO 2 emissions. However the carbothermic process has approached limits on the further reduction of greenhouse gas emissions, and only marginal improvements can be expected. Low temperature electrolysis using a dispersion medium to efficiently distribute charge throughout a colloid mixture including iron oxide provides an environmentally friendly method for performing an electrochemical reduction of Fe 2 O 3 to produce granular Fe. An electrical-ionic conductive colloidal electrode containing the electrochemically active species (Fe 2 O 3 particles), the liquid electrolyte (NaOH solution), and a percolating electrical conductor (carbon network) is utilized to produce Fe. The resulting simultaneous percolation of electrons and ions effectively increases the area of the current collector, and enables the process to function at higher currents and rate of charge transfer than static electrolysis.

    Abstract: Technologies are provided herein for real-time detection of motion and noise (MN) artifacts in electrocardiogram signals recorded by electrocardiography devices. Specifically, the present disclosure provides techniques for increasing the accuracy of identifying paroxysmal atrial fibrillation (AF) rhythms, which are often measured via such devices. According to aspects of the present disclosure, a method for detecting MN artifacts in an electrocardiogram (ECG) recording includes receiving an ECG segment and decomposing the received ECG segment into a sum of intrinsic mode functions. The intrinsic mode functions associated with MN artifacts present within the ECG segment are then isolated. The method further includes determining randomness and variability characteristic values associated with the isolated intrinsic mode functions and comparing the randomness and variability characteristic values to threshold randomness and variability characteristic values. If the randomness and variability characteristic values exceed the threshold characteristic values, the ECG signal is determined to include MN artifacts.

    Abstract: A global computer network method and apparatus for creating and deploying many types of intelligent tutoring systems across many different platforms is disclosed. A run time engine supports state graph pseudo tutors and JESS model tracing cognitive tutors, in both a client and server context. An Assistment Builder enables development, testing and deployment of the pseudo tutors, generally the tutorials formed of teacher composed problems. The system simplifies the process of tutorial construction to allow educator users with little or no ITS experience to develop content of problems and teaching strategies (i.e., format of problems including hints, messages and sequencing of related problems). The system provides a Web based interface as a means to build and store these tutorials. A reporting component is Web based and allows for live database reporting to teachers, showing how their students are performing. Automated analysis and reporting of experimental tutorials developed by teachers is included.
