This paper is devoted to the problem of constructing L-optimal designs for a trigonometric Fourier regression model with no intercept. The considers diagonal matrices L combination zeros and ones on main diagonal. It shown that in case when = I (i.e., identity matrix chosen as L), design coincides D-optimal one. In more general (when some elements are zero), it dimension can be reduced if optim...

1 To improve the monitoring of the invasive European woodwasp, both sexes of Sirex noctiliowere studied in a walk-in wind tunnel. We evaluated three trap types: unbaited traps, traps baited with a three-component pheromone lure and traps baited with a commercial Sirex kairomone lure and ultraviolet light. 2 When no lure was present, the black intercept trap caught more females than the clear ja...

Ligustrazine, the synthesized principle of a Chinese herbal remedy shown previously to be a pulmonary vasodilator, was tested in chronically hypoxic and normal rats. Pressure/flow, (P/Q), relations were measured in isolated perfused lungs during normoxia, hypoxia and after reversal of hypoxic vasoconstriction by increasing doses of ligustrazine. P/Q lines were linear over a wide range and extra...

We address optimal placement of vehicles with simple motion, to intercept a mobile target that arrives stochastically on a line segment. The optimality of vehicle placement is measured through a cost function associated with intercepting the target. With a single vehicle, we assume that the target either moves with fixed speed and in a fixed direction or moves to maximize the vertical height or...

Device drivers account for a substantial part of the operating system (OS), since they implement the code that interfaces the components connected to a computer system. Unfortunately, in the large majority of cases, hardware vendors do not release their code, making the analysis of failures attributed to device drivers extremely difficult. Although several instrumentation tools exist, most of t...

The ratio of intercept to slope of the Pomeron trajectory is derived in a phenomenological model based on a QCD approach to diffraction.

Previous research suggests that simple structure CFAs of Big Five personality measures fail to accurately reflect the scale's complex factorial structure, whereas EFAs generally perform better. Another strand of research suggests that acquiescence or uniform response bias masks the scale's "true" factorial structure. Random Intercept EFA (RI-EFA) captures acquiescence as well as the complex ite...
