Probability and distribution of green water events and pressures

This article proposes a method to quantify, first, the probability of occurrence of green water and, second, the expected maximum pressures during green water events using their statistical distribution for ships at forward speed. A large green water data set which represents 1945 hours of continuous sailing on full scale with different sea...

Estimates of extremes in the best of all possible worlds

In applied hydrology the question of the probability of exceeding a certain value occurs regularly. Often it is in a context where extrapolation from a relatively short time series is needed. It is well known that in its simplest form extreme value theory applies to independent identically distributed random variables. It is also well known that...

The strength of glass, hidden damage

The strength of float glass is a necessary engineering parameter. Determining this strength is a complex problem. Earlier results have shown that statistically bending test results are not a homogeneous group. To explain this, a theoiy of "hidden damage" is proposed. The essence of this theory is that the different sides of float glass are...

Statistics of measurement of noncommuting quantum variables: Monitoring and purification of a qubit

We address continuous weak linear quantum measurement and argue that it is best understood in terms of statistics of the outcomes of the linear detectors measuring a quantum system, for example, a qubit. We mostly concentrate on a setup consisting of a qubit and three independent detectors that simultaneously monitor three noncommuting operator...

Experiments on Unsteady Seperating Flow in an Open Channel

Experiments on unsteady separating flow past a sudden expansion in an open channel are described. To simulate tidal flow the flow rate in the approach channel varied as a half-sine with time. Different visualization techniques to obtain an insight into the behaviour of the separating vortex in time and space were used. Laser-Doppler velocimetry ...

Wind shear on the approach: An investigation on the infuence of a tower measured wind environment on the symmetric motions of a simulated aircraft in an automatic approach

Measured wind profiles from the Royal Netherlands Meteorological Institute 200 m meteorological tower at Cabauw have been used to estimate wind shear effects on the symmetric motions of an approaching aircraft. Wind profiles as well as an automatically approaching DC-9 aircraft have been simulated on an electronic analog computer. The study...
