Analytical Envelope-Function Theory of Interface Band Mixing
An analytical theory of intervalley mixing at semiconductor heterojunctions is presented. Burt’s envelope-function representation is used to analyze a pseudopotential Hamiltonian, yielding a simple d-function mixing between G and X electrons and light and heavy holes. This coupling exists even for media differing only by a constant band offset (i.e., with no difference in Bloch functions). [S00...

متن کاملan experimental study of turbulent mixing near a density interface
the entrainment of a stably stratified layer into a turbulent mixed layer in a confined region has been studied in the laboratory for different richardson numbers, ri. the results include direct observation of turbulent characteristics and density measurements using two high precision salinity meters. the measurements include turbulence intensity, scale of eddies near the interface and energy s...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولMultitouch Interface for Audio Mixing
Audio mixing is the adjustment of relative volumes, panning and other parameters corresponding to different sound sources, in order to create a technically and aesthetically adequate sound sum. To do this, audio engineers employ “panpots” and faders, the standard controls in audio mixers. The design of such devices has remained practically unchanged for decades since their introduction. At the ...
