WebOct 20, 2011 · The simulation results also show that a current density Jrock = 0.01–1 μ A/m 2 can lead to nighttime TEC variations of 1–30% as well as the formation of a nighttime plasma bubble (equatorial spread F) extending over the whole magnetic flux tube containing the earthquake epicenter.

Web1 day ago · The gas bubbles first detach from the titanium felt at 0.15 s, as shown in Fig. 7 A2. At 1.5 s (Fig. 7 A3), the bubbles emerged and formed a bubble flow inside the flow channel. With a further increase in time (Fig. 7 A4), a more dense bubble flow was formed in the flow channel at 3.6 s. Webreaching up to 10 bubbles per ˜ μ ˛. In between, an intermediate regime (Figures 1c and 1d) is characterized by similar sized, short-lived bubbles that do not merge, assembling at most in small clusters before bursting, with between 0.1 and 1 bubbles per ˜ μ ˛. This intermediate regime is due to the decoupled evolutions of the bubble Weband is quite simply the partial derivative along some arbitrary function v (if i remember right it's a direction), it's then noted that if the above limit exists for every v then we call the functional δ ( u; v) the first variation and denote it as δ ( u; ⋅) its then shown later in the course that for a functional J ( u) defined as green bay attorneys wills estates etc
