Accurate clinical assessments are essential for providing appropriate patient care. However, clinicians do not necessarily make accurate assessments, either because they are overloaded with other tasks, or because the computation of assessments is ambiguous. We used Brunswik‟s probabilistic functionalism to study how clinicians assessed the clinical state of a mannequin when they viewed recordi...

NQR of Cu in YBa2Cu3O ö 95 was investigated before and after low-temperature electron irradi­ ation as well as after annealing at several distinct temperatures up to 440 K. Irradiation with 2.76 MeV electrons (fluence (f)t = 2.2 ■ 1023 e_/m2) decreased the critical temperature Tc from 91.8 K to 89.5 K. The NQR spectra indicate that the e~ irradiation displaces so-called 0(4) atoms in the Cu-O c...

Fission tracks in minerals, such as apatite and zircon, generated by energetic nuclear fragments that result from spontaneous fission of U, are used for determining the age and thermal history of Earth’s crust. Taken together with other techniques, the data infer rates of tectonic uplift and landscape evolution [1]. At elevated temperatures, these tracks shrink in size and fragment into section...

In this article, the spectroscopic methods used to assess gem-quality diamonds are reviewed. From such measurements it is possible to determine, in the majority of cases, whether the colour of a stone is natural, or has been changed by some form of treatment—either HPHT processing, radiation damage and annealing, or a combination of both methods. Methods used to identify synthetic diamonds are ...

Dynamic properties such as natural frequencies and mode shapes are directly affected by damage in structures. In this paper, changes in natural frequencies and mode shapes were used as the input to various objective functions for damage detection. Objective functions related to natural frequencies, mode shapes, modal flexibility and modal strain energy have been used, and their performances hav...
