For unipolar hydrodynamic model of semiconductor device represented by Euler-Poisson equations, when the doping profile is supersonic, and boundary data are in subsonic region supersonic separately, system possesses shock transonic steady-states smooth steady-states. In this paper we study nonlinear structural stability linear dynamic instability these steady solutions. any relaxation time: 0 <...

Two organic gas speciation profiles (OG2403 and OG2404) for compressed natural gas (CNG) transit buses equipped with three-way catalysts (TWC) were developed in this work to complement the current CARB organic gas speciation profile database. The profiles were created based on chassis dynamometer test data of two transit buses equipped with TWCs running on CNG. Profile OG2403 was made for Stead...

AIMS/INTRODUCTION Insulin degludec/insulin aspart (IDegAsp) is a soluble co-formulation of long-acting insulin degludec (IDeg) and rapid-acting insulin aspart (IAsp). The present study investigated the pharmacodynamic properties of IDegAsp in Japanese patients with type 1 diabetes mellitus. MATERIALS AND METHODS In this randomized, double-blind, two-period, cross-over trial, 21 Japanese patie...

[1] Glacial occupation of alpine valleys results in a distinct signature in the long-valley profile, including steepening of the profile in the headwaters, flattening at lower elevations, and a step in the profile at the convergence of headwater tributaries. We present analytic results for glacial erosion patterns by making the following assumptions: (1) the initial profile is linear, (2) the w...

when a dam is constructed on a river path, inevitably sedimentation of alluvial materials occurred. therefore, the initial capacity of the reservoir reduce gradually, and if don’t predict the effects of this phenomena and its proper control methods, the application of the reservoir may be affected. the findings of this thesis confirm that, the sedimentation in reservoirs and the variations of t...

Examining the cooling rate using impingement of air jet finds a wide application in electronic packaging and micro-scale fluid heat interaction systems, While the prediction of Nusselt profile at low nozzle-target spacing is a big issue. The plot of area average Nusselt number magnitude against the nozzle-target spacing (Z/d) shows a gradual decrement in the profile upto Z/d = 1 and beyond that...
