Abstract: The system described herein implements synchronized playback of data related to an event. The system receives information that defines a type of event, as well as a time at which the event occurs. Moreover, the information defines an environment in which the event occurs. The system maps the type of event to data sources associated with the environment. Furthermore, the system maps the time at which the event occurs to a predefined timeframe that precedes and/or overlaps with the time at which the event occurs. The system retrieves respective datasets from the data sources and generates respective visualizations for the datasets. The system displays the visualizations in a layout and provides user controls that enable a user to implement synchronized playback of the event from the perspective of the data sources. For example, the synchronized playback can cycle through a sequence of data display states for the datasets.

Abstract: The present invention discloses a Double Metal Cyanide (DMC) catalyst(s) useful for the production of polyether polyols (PEPO) and a less energy intensive room temperature method for the synthesis thereof. The catalyst(s) comprises of a DMC complex, an organic complexing agent, i.e., ethylenediaminetetraacetic acid (EDTA) and other co-complexing organic agents, e.g., t-BuOH, PEPO of composition ranging from about 1 to 10 wt %, wherein the average molecular weight of PEPO used ranged from 200 to 1000. A method of preparing a series of DMC catalyst(s) at room temperature with varying compositional ratios of the complexing and co-complexing agents targeting a wide range of PEPO of varying kinematic viscosity range is also disclosed. These DMC catalyst(s) are amorphous, highly active, and easily separable from product PEPO with recyclability/recoverability, making the product PEPO better industrially applicable and DMC catalyst more cost-effective.
