Abstract: Exemplary embodiments provide a refrigeration system having an interior space cooled by a plurality of cooling. Each cooling unit is capable of operating either synchronously when in communication with a control panel or under independent operation. Each cooling unit is modularly and replaceable without the use of tools by means of a quick connect system. The cooling units use a heat exchanger cooled by chilled water and make use of an electronic super heat control and electronic expansion valve to regulate the flow of refrigerant for improved efficiency.

Abstract: Student data-to-insight-to-action-to-learning analytics system and method use an evidence-based action knowledge database to compute student success predictions, student engagement predictions, and student impact predictions to interventions. The evidence-based action knowledge database is updated by executing a multi-tier impact analysis on impact results of applied interventions. The multi-tier impact analysis includes using changes in key performance indicators (KPIs) for pilot students after each applied intervention and dynamic matching of the pilot students exposed to the appropriate interventions to other students who were not exposed to the appropriate interventions.
