Infants and young children may be exposed to a variety of dangerous situations when left sleeping in cots, chairs, or beds. A review of 30 cases of accidental asphyxia occurring in infants and young children who had been left to sleep unattended was undertaken from the necropsy and consultation files of the Adelaide Children's Hospital. Causes of death included hanging from loose restrainers, c...
An improved Eulerian method with a novel morphologic model is developed based on the direct numerical simulation (DNS) approach to study local scour. A movable immersed boundary proposed prescribe geometry of riverbed. Two techniques, namely Simultaneous Bed Adjustment Method (SBAM) and (Segment Plane Method) SPM, are complex time changing The SBAM technique considers sand sliding in SPM an alg...
We present an integrated approach to modeling and control of electrostatically-actuated MEMS. The model consists of a set of fixed or movable electrodes, each coupled to the others through a resistor and capacitance, and to ground through a capacitance and a voltage or current source. This formulation incorporates movable structures, control electrodes, sense electrodes, and parasitic capacitan...
In this note, we give a Morse-type bigness criterion for the difference of two pseudoeffective (1, 1)-classes by using movable intersections. As an application, we give a Morse-type bigness criterion for the difference of two movable (n− 1, n− 1)-classes.
تقاضا برای اُلفین های (آلکِن های) سبک مانند پروپن، بوتن و ایزوبوتن و محصولاتی که از این اُلفین ها تولید می شود، بالا و رو به فزونی است. چون منابع فسیلی (طبیعی) فاقد الفین های سبک می باشند و بیشتر آنها شامل هیدروکربن های اشباع شده و آروماتیکها می باشد، روش های سنتزی برای تولید اُلفین های سبک اجتناب ناپذیر است. یکی از راههای تولید اُلفینهای سبک، هیدروژن زدایی آلکان متناظر- حذف یک مولکول - با آنها می ب...
The armored layer is crucial for protecting the riverbed. bed of river a movable material that protects below surface layer. This study aimed to develop formulas estimate thickness mobile armor with noncohesive materials and establish correlation between flow velocity shear stress under conditions erosion sedimentation. research methods included field measurements, laboratory tests, numerical s...
This laboratory study focused on the effect of a submerged vane-field flow pattern and bed morphology near inside entrance reach movable 90° lateral diversion. The system was modelled under live conditions for water discharge ratio ?0.2. Two experiments were run until equilibrium reached: with without installed close to diversion control transfer sediments into channel. associated 3D field meas...
