A real time spectrum to dose conversion system

A system has been developed which permits the determination of dose in real time or near real time directly from the pulse-height output of a radiation spectrometer. The technique involves the use of the resolution matrix of a spectrometer, the radiation energy-to-dose conversion function, and the geometrical factors, although the order of matrix operations is reversed. The new technique yields a result which is mathematically identical to the standard method while requiring no matrix manipulations or resolution matrix storage in the remote computer. It utilizes only a single function for each type dose required and each geometric factor involved

Theory of zone radiometry

A spectroscopic instrumentation system was developed which was used to measure temperature and concentration distributions in axisymmetric and two dimensional combusting flows. This measurement technique is known as zone radiometry

Effects of systematic errors on the mixing ratios of trace gases obtained from occulation spectra

The influence of systematic errors in the parameters of the models describing the geometry and the atmosphere on the profiles of trace gases retrieved from simulated solar occultation spectra, collected at satellite altitudes, is investigated. Because of smearing effects and other uncertainties, it may be preferable to calibrate the spectra internally by measuring absorption lines of an atmospheric gas such as CO2 whose vertical distribution is assumed rather than to relay on externally supplied information

Analysis of radiation and meteoroid satellite data

The data obtained in earth orbit by the Radiation and Meteoroid Satellite (RMS) were interpreted and reduced to a form which will be usable by future space experimenters. The required tasks are detailed. Computer programs were written which lifted the raw data and associated emphemeris data from the GFE magnetic tapes. The engineering data was then used to evaluate the performance of the spacecraft and the experiments. The radiation data was used to prepare flux, spectral, and dose maps of the South Atlantic magnetic anomaly where possible. The meteoroid data was used to determine a rough estimate of the meteoroid flux and in general evaluate the performance of the thin-film meteoroid sensors. The degree of success of the RMS mission was evaluated in light of the separation anomaly which occurred between RMS and OFO during launch

Autocorrelation of Random Matrix Polynomials

We calculate the autocorrelation functions (or shifted moments) of the characteristic polynomials of matrices drawn uniformly with respect to Haar measure from the groups U(N), O(2N) and USp(2N). In each case the result can be expressed in three equivalent forms: as a determinant sum (and hence in terms of symmetric polynomials), as a combinatorial sum, and as a multiple contour integral. These formulae are analogous to those previously obtained for the Gaussian ensembles of Random Matrix Theory, but in this case are identities for any size of matrix, rather than large-matrix asymptotic approximations. They also mirror exactly autocorrelation formulae conjectured to hold for L-functions in a companion paper. This then provides further evidence in support of the connection between Random Matrix Theory and the theory of L-functions

Attachment Style and Leader-Member Exchange: The Role of Effort to Build High Quality Relationships

Purpose The purpose of this paper is to examine psychological attachment styles (secure, anxious, and avoidant) as antecedents to leader-member exchange (LMX) quality both directly and through their impact on employees’ efforts to build high quality LMX relationships. Employees with secure attachment styles are proposed to be successful at building high quality LMX relationships while employees with anxious and avoidant styles are proposed to display the opposite effect. Design/methodology/approach Data were collected through a survey of 213 employees nested in 37 work groups. Hypotheses were tested using multilevel modeling within MPlus. Findings Results indicated that secure and anxious attachment styles were associated with LMX only by impacting the exertion of effort specifically aimed at relationship development with the manager. Alternatively, the avoidant style was directly and negatively linked to LMX but not associated with effort undertaken to build a high quality relationship. Practical implications The effects of attachment style on effort to develop high quality LMX relationships reveal that subordinate attachment style may impact those subordinates’ ability and interest in developing positive LMX relationships. Therefore, managers may need to purposively deviate from typical LMX development processes in order to create a more conducive environment for developing high quality relationships with subordinates of differing attachment styles. Originality/value This study is one of the first to examine the mediating impact of effort to build high quality LMX relationships given personal propensities (attachment style) to form relationships in the workplace
