Downslope windstorms (DWs) are responsible for wildfires, wind gusts, and turbulence on the lee side of Taebaek Mountains in Yeongdong (YD) region Korea. We classified synoptic conditions YD using a self-organizing map (SOM). For windstorm events from 1979 to 2019, sea level pressure anomalies were used train SOM. It was found that patterns could be into three representative types: (1) south-hi...

Absolute and Relative Stability. A control system is called absolutely stable if the controlled transfer function Hd(s) from the reference signal yd(s) to the output signal y(s) has all of its poles in the open left half plane. One technique for determining absolute stability of a control system is the Routh-Hurwitz stability analysis technique. This very useful technique is presented in Sectio...

We present some results on the shape and size of the percolative region of the nearest neighbor ferromagnetic Ising model on yd. The percolat ion properties of the connected clusters of (say) the + spins in equilibrium states of these models have been studied because of interest in the properties of correlated percolat ion (see Refs. 1 and 2) and because of some questions related to the ferroma...

We combine our ice-sheet and climate models to formulate a deductive theory of abrupt changes pertaining Heinrich/Dansgaard–Oeschger (H/DO) cycles the last deglaciation punctuated by Younger Dryas (YD). Since they are all accompanied ice-rafted debris, we posit their common origin in calving ice sheet due thermal switch at its bed, which naturally endows abruptness these signals millennial time...

In an effort to understand how alpine environments from the western Mediterranean region responded climate variations since last glacial-interglacial transition, a detailed chronological control and sedimentological analysis, supported by magnetic susceptibility, total organic carbon C/N data, were carried out on sedimentary record of Laguna Seca (LS). This is latitudinal altitudinally (2259 ma...

We have used electron diffraction and neutron powder diffraction to elucidate the structural properties of superconducting Na x CoO 2 ·yD 2 O over a wide compositional range. Our measurements show that superconducting samples exhibit a number of supercells ranging from 1 3 a * to 1 15 a * , but the predominant modulation, observed also in the neutron data, is a double hexagonal cell with dimens...
