The linearity of thermoluminescence (TL) dose response curve, in low dose levels, is affected by background signals appearing at the tail of the glow curves. The effects of these signals also restrict the use of the high temperature glow peaks in many applications. In this study, a new reading out procedure was presented to reduce the background signals and increase the resolution of the high t...

numerous types of development projects, Adams reported similar numbers, where only about one-fourth of all projects entering development become a market success (2004). Datta and Mukerjee (2001) stated that “successful project completion depends to a great extent on the early identifi cation of immediate risks.” Jiang et al. (2002), using factor analysis, confi rmed their hypothesis that risks ...

In this paper, we propose a robust and real‐time localization method for dynamic environments based on a sensor network; the method combines landmark image information obtained from an ordinary camera and distance information obtained from sensor nodes in an indoor environment. The sensor network provides an effective method for a mobile robot to adapt to changes and gu...

Tests of CP violation by appropriate momentum correlations in Z → 3 jets and in particular in Z → bb̄X probe CP-violating effective couplings – that manifest themselves as form factors – which conserve the quark chirality and quark flavour. By giving two examples we show that such couplings can be induced at one-loop order in extensions of the Standard Model with CP violation beyond the Kobayash...

We propose a factor model which allows a parsimonious representation of the time series evolution of covariances when the number of series being modelled becomes very large. The factors arise from a standard stochastic volatility model as does the idiosyncratic noise associated with each series. We use an efficient method for deriving the posterior distribution of the parameters of this model. ...

Maximum likelihood factor analysis provides an effective method for estimation of factor matrices and a useful test statistic in the likelihood ratio for rejection of overly simple factor models. A reliability coefficient is proposed to indicate quality of representation of interrelations among attributes in a battery by a maximum likelihood factor analysis. Usually, for a large sample of indiv...

This paper presents a simple and effective method to fabricate a polydimethyl-siloxane (PDMS) microlens array with a high fill factor, which utilizes the UV proximity printing and photoresist replication methods. The concave microlens array mold was made using a printing gap in lithography process, which utilizes optical diffraction of UV light to deflect away from the aperture edges and produc...

This case study describes an effective method to ameliorate the cognitive load caused by new terminology and concepts in lectures. Ten online pre-lecture resources whose design was underpinned by the principles of cognitive load theory were provided to a class of 49 first year university level chemistry students. Each resource introduced a number of key concepts to the forthcoming lecture and i...
