Abstract: A computerized method for controlled testing, comprising: providing a design specification for event data, the design specification including at least one of an event data source, an event data filter, and an event format; retrieving testing metrics; configuring testing events based on the design specification, by: retrieving testing events from the event data source specified in the design specification; filtering the retrieved testing events based in the design specification; and formatting the filtered testing events based on the design specification; generating analysis data by applying testing metrics to the configured event data; generating output data based on testing rules; and generating a user interface to display the output data.

Abstract: Disclosed herein are systems and methods for a system for distributing user requests. The system may comprise a memory storing instructions and at least one processor configured to execute instructions to perform operations.

Abstract: A system for live analysis of testing logs. The system including a memory and a processor configured to execute the instructions to perform operations including receiving a plurality of log entries; processing the plurality of log entries; storing the processed plurality of log entries in a database having an inverted index; receiving a query from a user device; returning test data, metadata, and statistics related to the one or more log entries; displaying the test data, the metadata, and the statistics on a GUI; comparing an exposure ratio to a range, the exposure ratio being based on a first amount of log entries associated with a first test version and a second amount of log entries associated with a second test version; and upon determining the exposure ratio is outside of the range, directing all requests from subsequent test users to a default test version.

Abstract: Embodiments of the present disclosure include computer-implemented systems and methods for predicting a minimum detectable effect. The system may include at least one processor configured to execute instructions to perform steps. The steps may include sending a first webpage to a first user device and a second webpage to a second user device. The second webpage may include at least one characteristic different than the first website. The steps may include collecting user interaction data from the first and second user devices and determining a current minimum detectable effect of a user experience. The steps may include retrieving a set of historic minimum detectable effect values associated with an earlier period of time and determining a percentile rank of the current minimum detectable effect based on the retrieved set of historic minimum detectable effect values.

Abstract: The present invention relates to a multi-core fuel rod for research reactor and a manufacturing method thereof and, more particularly, to a multi-core fuel rod for research reactor in which monolithic fuel cores made of uranium-molybdenum alloy are disposed in an aluminum matrix in a multi-core form, and a manufacturing method thereof. The multi-core fuel rod in accordance with the present invention provides a minimized contact surface area between nuclear fuel and aluminum, and reduces the formation of pores and swelling by restraining formation of reaction layer to avoid excessive reaction between the fuel and aluminum. Therefore, improved stability of nuclear fuel can be obtained by minimizing temperature rise as well as achieving high density and thermal conductivity of the fuel.
