I get this error "Error in external library. See system log for details", it seems like 7 times out of 10 whenever I try to create a FIXED_AXIS_GUIDING_CURVES operation. Sometimes it helps when I close NX and reopen it and try again but sometimes it doesn't. If I check the sysl...
In the second embodiment, two of the wires 50 are located along the major axis of the elliptical tube 41 while the other wires are located along the minor axis. In this embodiment, the two wires 50 located along the major axis may extend from the tube 41 at a different angle than the...
Identifying the primary site of metastatic cancer is critical to guiding the subsequent treatment. Approximately 3–9% of metastatic patients are diagnosed with cancer of unknown primary sites (CUP) even after a comprehensive diagnostic workup. However, a widely accepted molecular test is still not ...
the angle between the body’s y-axis yb and the earth plane (x , y ), and pitch (θ ) is expressed as the angle between the e e e body’s x-axis x and the earth plane (x , y ) (Figure 4): 2 b e e where g ≈ −9.81m/s is the localized acceleration due to gravity...
Flocking for fixed-Wing Unmanned Aerial Vehicles (UAVs) is an extremely complex challenge due to fixed-wing UAV’s control problem and the system’s coordinate difficulty. Recently, flocking approaches based on reinforcement learning have attracted attention. However, current methods also require that ...
The positions of the test specimens are determined based on the coordinates shown in Figure 22: The x-axis represents the string line direction in the side view of the vane, the y-axis indicates the height direction at the edge of the vane, and the z-axis represents the surface height ...
The vertical formation also expects the differences between leader and followers are as small as possible in coordinates on the x-axis. For guiding the followers to change the formation, this paper utilizes the absolute difference value of x coordinates to modify the flocking reward. The modified ...
where 𝛼∈ℝ denotes the angle of attack, 𝑞∈ℝ denotes the body-axis pitch rate, 𝜃∈ℝ denotes the pitch angle, 𝛿𝑒∈ℝ is the system input, denoting the elevator deflection angle, the system output is the flight-path angle denoted by 𝑦=𝛾=𝜃−𝛼, and 𝒚...
According to the position estimation results, the error curves of KC and KO showed more fluctuations compared with the proposed method SE. For instance, the maximum errors of KC and KO even reached 132 m at the Y-axis and 14 m at the X-axis. This can easily deviate the UAV from the ...
Along the combustion chamber axis and under a constant primary air flow rate, the bed temperatures and the mass loss rate were measured as functions of time. Moreover, the gas mixture components such as O2, organic carbon (Corg), CO, CO2, H2O, H2, SO2, and NOx (NO + NO2) were ...
