This research investigates the performance of medium density fiberboard (MDF) with respect to hot press parameters. The board, type glue, and production efficiency determine optimum temperature pressure for pressing. actual inside MDF board determines properties final product. Hence, optimal parameters desired product are experimentally obtained. Moreover, is investigated in terms its vertical ...

the density and polarization profiles of the dipolar hard ellipsoids confined between hard walls are studied using the density functional theory (dft). the hyper-netted chain (hnc) approximation is used to write excess grand potential of the system with respect to the bulk value. the number density is expanded up to zero and first order in polarization to find the results. for the zero order in...

Vertical electron density profile is an important source of information on the Earth’s ionosphere. It is well known that such vertical electron density profile can be retrieved using LEO (Low Earth Orbit) satellite RO (radio occultation) data. With more and more LEO satellite data available (such as CHAMP, SAC_C, GRACE, COSMIC), the retrieved vertical electron density can be more accurate if so...

The general relativistic model of Cooperstock & Tieu, which attempts to fit rotation curves of spiral galaxies without invoking dark matter, is tested empirically using observations of the Milky Way. In particular, predictions for the mass density in the solar neighbourhood and the vertical density distribution at the position of the Sun are compared with observations. It is shown that the mode...

It has been known for a few years that the occupation measure of several models of embedded trees converges, after a suitable normalization, to the random measure called ISE (Integrated SuperBrownian Excursion). Here, we prove a local version of this result: ISE has a (random) Hölder continuous density, and the vertical profile of embedded trees converges to this density, at least for some such...

Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...
