Delft University of Technology (DUT) screened her (non-native English) scientific staff on their level of language proficiency over the year academic 2006/2007. In this paper the large scale operation, involving planning, policy decisions, assessment means, advise and training are discussed. Results are framed against the background of becoming...

Photo- and thermoluminescence (TL) spectra of NaLaF4:Ln3+ (Ln = Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm) and NaLaF4:Ce3+, Ln3+ (Ln = Nd,Sm,Ho,Er,Tm) are presented and used together with the empirical Dorenbos model in order to establish the 4f energy level positions of all tri- and divalent lanthanide ions doped in NaLaF4. The information will be...

CeBr3 crystals have been studied to assess their utility as potential gamma ray spectrometers for future ESA planetary missions. Pulse height spectra, scintillation time profiles, X-ray excited emission spectra, and photoluminescence spectra have been recorded as a function of temperature between 78 and 600 K. In addition, the influence of...

Corrosion of metals has an enormous economic impact. Fortunately, the rate at which corrosion processes take place can be reduced, often to a point where, at least temporarily, corrosion is virtually non-existent. One of these, corrosion-control methods is barrier protection. The concept of barrier rotection is to separate the metal substrate...

The influence of different wing kinematic models on the aerodynamic performance of a hovering insect is investigated by means of two-dimensional time-dependent Navier–Stokes simulations. For this, simplified models are compared with averaged representations of the hovering fruit fly wing kinematics. With increasing complexity, a harmonic model,...

It has been generally accepted that the noise in continuous GPS observations can be well described by a power-law plus white noise model. Using maximum likelihood estimation (MLE) the numerical values of the noise model can be estimated. Current methods require calculating the data covariance matrix and inverting it, which is a significant...

Het technisch rapport ruimtelijke kwaliteit heeft als doel het werken aan ruimtelijke kwaliteit concreet te maken in de planvorming voor rivierveiligheid, zowel in dijkversterking- als rivierverruimingprojecten. Om dit doel te bereiken besteedt het technisch rapport aandacht aan de methode die kan worden toegepast om ruimtelijke kwaliteit te...

A combined photoconductivity, absorption, and thermoluminescence study was performed to understand the absence of luminescence from Ce3+ in LaAlO3:Ce3+. It is demonstrated that the absence of luminescence is the result of Ce3+ ionization from the 5d excited states, which are all located in the conduction band. Ce3+ ionization is accompanied by...

Ferromagnetism is observed below 10 K in [Bi0.75Te0.125Mn0.125]Te. This material has the BiTe structure, which is made from the stacking of two Te-Bi-Te-Bi-Te blocks and one Bi-Bi block per unit cell. Crystal structure analysis shows that Mn is localized in the Bi2 blocks, and is accompanied by an equal amount of TeBi antisite occupancy in the...

A glass-ceramic thermal neutron imaging plate material is reported. The material consists of a neutron sensitive 2B2O3–Li2O glass matrix containing nanocrystallites of the storage phosphor BaCl2:Eu2+. When doped with 0.5?mol?% Eu2+, the neutron induced photostimulated luminescence (PSL) conversion efficiency of the 10B enriched glass-ceramic is...

In the literature, many methods are available for estimation of the variance of the noise in magnetic resonance (MR) images. A commonly used method, based on the maximum of the background mode of the histogram, is revisited and a new, robust, and easy to use method is presented based on maximum likelihood (ML) estimation. Both methods are...
