Block iterative methods are applied to hydrodynamic simulations of a one-dimensional (1-D) submicrometer semiconductor device. We show that block successive underrelaxation (SUR) converges with a fixed relaxation factor w = 0.13 for simulations at 300 K and w = 0.04 at 77 K . To demonstrate the robustness of the block iterative method, we present numerical simulations of a steady-state electron...

Ground-penetration radar (GPR) is a geophysical tool widely applied in archaeological and forensic research, such as identifying the exact position of graves. A detailed GPR survey was conducted on cemeteries Permatang Pasir Titi Teras, Penang Island. Moving 500MHz antenna along parallel transects inside grids used to collect data. The study’s aim present two case studies with varying soil type...

Critical transition zones, such as aquatic–terrestrial interfaces, have been recognized as important features in landscape ecology. Yet changes in the community structure of soil and sediment biota across aquatic–terrestrial boundaries remain relatively unstudied. We investigated the community structure of the dominant fauna, namely nematodes, rotifers and tardigrades, across lake sediment–soil...

In a structure of an epitaxial film yttrium iron garnet (YIG) with crystallographic orientation (111) 11.8 μm thick and 5 nm platinum (Pt) deposited on its surface, the effect EMF generation in during propagation magnetostatic waves (MSW) was studied at values tangential constant magnetic field H less than saturation H_s~65 Oe YIG film. The experiments were performed geometry where parallel to ...

Abstract Subri River Forest Reserve (SR) is the most extensive forest area in Ghana with an accompanying rich floral species. Over years, logging from both legally prescribed and illegal operations remain predominant disturbance SR. Gap creation following crucial determining tree species composition diversity. Hence, study evaluated diversity of naturally regenerated gaps different sizes and, a...
