Five Minute LOI Test

Loss-on-ignition (LOI) is an important thermo-chemical property test for many foundry materials. Applications include new sands, green sand systems, chemically bonded cores and molds, sand additives, and reclaimed sands. LOI has been an important quality control measure carried out off-line. The AFS-defined LOI test uses a muffle furnace that is time consuming, often requiring three hours; a mo...

LOI to JLab PAC 31 RF Cherenkov picosecond timing technique for Jlab 12 GeV physics program

A new particle identification device for Jlab 12 GeV physics program is proposed. It is based on the measurement of time information by means of a new radio frequency picosecond phototube (RFPP) and time measuring concept. The expected time measurement precision for Cherenkov time-of-flight (TOF) detector in a “head-on” geometry based on RFPP is about or less than 5 picoseconds, FWHM. The propo...

Levels of Interaction (LoI): A Model for Scaffolding Learner Engagement in an Immersive Environment

In this paper we present a theoretical framework describing an original method for the design of intelligent tutoring environments, building upon the notion of shared attention to scaffold learner engagement. This framework, defined as the Levels of Interaction (LoI) approach, places a focus upon using techniques derived from leisure and serious games in order to foster engagement with the lear...
