Abstract: Methods, apparatuses, and computer-readable media utilize data stacking to facilitate identification and/or correction of data interpretation conducted for a subsurface formation. Related data sets, such as well logs, may be displayed along with markers representing a common entity in the related data sets, such as formation features in a surface formation, and a visualization of stacked data may be generated and centered on the markers to highlight mis-alignment of any of the markers.

Abstract: A method for detecting fault in a power transmission line of a power transmission system and protection system using the same. The method includes: obtaining a system parameter of the power transmission system, adjusting protection reachability of a fault detecting element based on the obtained system parameter such that the adjusted protection reachability of the fault detecting element is applicable to a predetermined protection range, identifying whether there is an internal fault occurring on the transmission line using the adjusted fault detecting element, and generating a fault detection decision signal indicating the identified fault. If the predetermined protection range is desirable for the fault detecting element, its protection reachability may be adjusted in consideration of the influence imposed by the SIR such that the reach point of the adjusted fault detecting element can be extended to approach the end of the predetermined protection range.

Abstract: A current detection circuit includes a current sampling branch, a switch branch, a first current mirror branch, a capacitor branch, a feedback branch and a control branch. The control branch receives the second current and outputs the first current and the first voltage signal. The current sampling branch outputs a first discharging current. The switch branch establishes and disconnects the connection between the first current mirror branch and the capacitor branch. The capacitor branch is charged in response to the first charging current and discharged in response to the first discharging current. The first current mirror branch outputs the first charging current. The feedback branch adjusts the second charging current to adjust the first charging current, so that the total charge of the capacitor branch is balanced with the total charge of discharge within one switching cycle, so that the first current is represented by the first charging current.

Abstract: A wind direction and a wind speed are readily and accurately estimated at a desired position without using a wind direction and velocity sensor. Movement instruction means of a wind estimation system instructs an unmanned aerial vehicle (UAV), which includes a sensor unit that detects information about a position change, to move. Fall control means causes the UAV to free fall after the UAV is moved according to the instruction of the movement instruction means. Estimation means estimates at least one of a wind direction and a wind speed at a fall position based on the information about the position change detected by the sensor unit during a fall of the UAV.

The threshold value may indicate a threshold likelihood of the hail event occurring or a threshold period of time before occurrence. The method may include determining a wind direction at the predicted time at which the hail event is likely to occur and stowing photovoltaic modules based on the wind direction.
