Abstract: A two-phase liquid-gas flow system for testing electrical submersible pumps (ESP) includes an oil pump, a water pump, an oil storage tank, a water storage tank, a pressurized air system, an air pressure regulator (PR), and a transparent test section with the ESP. The pressurized air system includes air storage tanks, compressors, and air flow meters (AFM). The oil pump and the water pump supply oil and water from the oil storage tank and the water storage tank through an oil flow meter and a water flow meter, respectively, to the transparent test section. The air storage tanks are in fluid communication with the PR by valves, which channel air through the PR and the AFMs to the transparent test section. A camera is provided to capture photos and videos of flow patterns of the working fluid in the transparent test section.

Abstract: A method of detecting sensor malfunction in an automated guided vehicle, AGV, including for at least two different pairs of wheel units in a motion state of the AGV, calculating a motion value for at least one motion variable of a body of the AGV based on sensor data from a wheel sensors and/or a steering sensors; for at least one motion variable, calculating a difference between the motion values for at least two different pairs; and determining that there is a malfunction in one or more of the wheel sensors and the steering sensors if one of the at least one difference exceeds a threshold value associated with the respective motion variable.

Abstract: Systems and methods are disclosed for implementing an event based retention schedule for a read only file. When a regular file is to be converted to an event based retention read only file, an “event-retain” property may be enabled on the file allowing the feature to be implemented. Then, that file may have its permissions changed to read only. This will allow the file to be changed to a read only file without using a default retention time. Then, once the event is triggered, the retention time may be set so the file can be scheduled for automatic deletion.

Abstract: A multiphase flow calibration semi-closed loop system includes an oil-gas-water separation unit, a multiphase flow calibration unit, a single phase flow calibration section, a gas flow section, a flow data acquisition unit, and a programmable logic controller (PLC). The system is designed to have a two-step calibration process. In a first step, single phase water flow meters and single phase oil flow meters of the system are calibrated independently. In a second step, multiphase flow meters or multiphase water cut meters are calibrated using the pre-calibrated water flow meter, pre-calibrated oil flow meter, and the pre-calibrated gas flow meter. In doing so, the oil-gas-water separation unit, the multiphase flow calibration unit, the single phase flow calibration section, and the gas flow section communicate with the flow data acquisition unit providing real time data. Thus, the PLC connected to the flow data acquisition unit can perform the required calibration processes.

Abstract: Method and system relating to firewall configuration have been discussed. According to an embodiment, a method comprises specifying at least one firewall configuration at a first server at which the at least one firewall configuration is to be enforced; to a plurality of servers, distributing the at least one specified firewall configuration along with a set of parameters to identify the plurality of servers at which the at least one specified firewall configuration has to be enforced; receiving a data packet by a second server of the plurality of servers from the first server; and comparing the at least one specified firewall configuration with a default set of firewall configuration while receiving the data packet by the second server of the plurality of servers from the first server.

Abstract: A structural, load-bearing panel useful in constructing multistory buildings may have a panel height, panel width, and panel thickness, and may include a first layer comprising at least 75 wt. % of concrete, relative to a total weight of the first layer; an insulation layer comprising flexible polymer, the insulation layer having a thickness of at least 5 cm; and a second layer comprising at least 75 wt. % concrete, wherein the insulation layer is sandwiched between the first and second layers, and wherein the panel is suitable to be set in any of a planar, curved, and polyhedral cross-sectional shape. Set panels are not flexible, though the flexibility of the insulation layer, particularly of a polyethylene foam, may allow the panel to have a curved, or polyhedral cross-section while still serving as a structural support.
