From Preliminary Aircraft Cabin Design to Cabin Optimization - Part I -
This paper conducts an investigation towards main aircraft cabin parameters. The aim is two-fold: First, a handbook method is used to preliminary design the aircraft cabin. Second, an objective function representing the “drag in the responsibility of the cabin” is created and optimized using both an analytical approach and a stochastic approach. Several methods for estimating wetted area and ma...
متن کاملLecture Notes ( Wuhan 2006 )
By linearity, the above two questions are reduced to the unique continuation property (UCP) for the wave equation. Due to finite speed of propagation, the (UCP) holds only for T > 0 large enough and Ω will be supposed a connected domain. For instance, for a sufficiently smooth boundary, if T > 2max { dist (x, Γ) , x ∈ Ω}, then by Holmgren uniqueness theorem N = {u ∈ H (Ω× (0, T )) being a solut...
متن کاملThe Manhigh sealed cabin atmosphere.
W H E N the Manhigh capsule system was being designed in the fall of 1955, the pr imary objective was a maximum performance system of minimum weight that could lift a man into a space equivalent environment for twenty-four hours. This objective 'had to be met safely and supply an answer to what the man could :do if any specific componem failed. Beyond this, an effort was made to provide him wit...
متن کاملEstimation of Short-Term Effects of Air Pollution on Stroke Hospital Admissions in Wuhan, China
BACKGROUND AND OBJECTIVE High concentrations of air pollutants have been linked to increased incidence of stroke in North America and Europe but not yet assessed in mainland China. The aim of this study is to evaluate the association between stroke hospitalization and short-term elevation of air pollutants in Wuhan, China. METHODS Daily mean NO2, SO2 and PM10 levels, temperature and humidity ...
متن کاملEnclosed Five-Wall Immersive Cabin
We present a novel custom-built 3D immersive environment, called the Immersive Cabin (IC). The IC is fully enclosed with an automatic door on the rear screen, and thus very different from existing CAVE environments. Our IC, the construction of the projection screens and stereo projectors as well as the calibration procedure are explained in details. The projectors are driven by our Visual Compu...
