Comparison between the statistical discrete gust method and the power spectral density method

The Power Spectral Density method and the Statistical Discrete Gust Method to calculate aircraft design loads due to atmospheric turbulence are compared qualitatively and quantitatively on the basis of the load exceedance curves for certain aircraft models. It is shown that both methods are related to each other, giving the same results for...

An analytical model of the write and read process in digital magnetic recording with a linear recording medium

A study of surface treatment of aluminium alloy samples by measuring light stimulated electron emission and contact potential

Tests on samples anodized in a tartrate solution indicated that porefree thin oxide films prevent almost all light stimulated electron emission. Probably "pores" are requisite for emission. The c.p. and emission as function of the pickling time in chromic-sulfuric acid solution could be explained qualitatively. The micro etch pit structure with...

Refurbishment of Residential Buildings: A Design Approach to Energy-Efficiency Upgrades

Refurbishing the existing building stock is an acknowledged issue in the building industry. Even though awareness has been raised, the design phase of refurbishment projects is often problematic. The decisions taken in the early stages of the design determine the final result; however, the assessment of the environmental performance only happens...

Stochastic parameterization of convective area fractions with a multicloud model inferred from observational data

Observational data of rainfall from a rain radar in Darwin, Australia, are combined with data defining the large-scale dynamic and thermodynamic state of the atmosphere around Darwin to develop a multicloud model based on a stochastic method using conditional Markov chains. The authors assign the radar data to clear sky, moderate congestus,...

Lecture notes on "The Role of Rivers to Mankind"

It is the task and target of River Engineering as a profession to provide all the tools for arriving at an optimum utilization of the potential resources, optimum in the sense of promoting the beneficial characteristics of the river and eliminating or at least checking the adverse qualities. To strive for this aim, there must be a scientific...
