Results of a preliminary study of seasonal variations of gold content in Harris Creek were given by Day and Fletcher (1987a). Suhsequently,DayandFletcher(1987h)presenteda model for transport of gold in Harris Creek and suggested that heavy-mineral concentrates collected from bar-head gravels could provide a good exploration medium. To study seasonal variations at such sites, bar-head gravels at...

This report is devoted to preconditioning techniques for the matrix-free truncated Newton method. After a review of basic known approaches, we propose new results concerning tridiagonal and pentadiagonal preconditioners based on the standard BFGS updates and on numerical differentiation. Furthermore, we present results of extensive numerical experiments serving for the careful comparison of sui...

this paper presents a new formulation for warehouse inventory management in a stochastic situation. the primary source of this formulation is derived from fp model, which has been proposed by fletcher and ponnambalam for reservoir management. the new proposed mathematical model is based on the first and the second moments of storage as a stochastic variable. using this model, the expected value...

G rowing up on a big piece of land in Texas, Dan Fletcher explored how things in both the natural and mechanical realms were put together. But in his early school days a particularly traumatic dissection of a bloated fetal pig sent him in the direction of " hard, clean " sciences. By the end of his doctoral work developing new instruments that combined optical and atomic force microscopy (AFM),...

Mode fitting or “peak-bagging” is an important procedure in helioseismology allowing one to determine the various mode parameters of solar oscillations. We have recently developed a new “pseudo-global” fitting algorithm as a way of reducing the systematic bias in the fits of certain mode parameters that are seen when using “local” fitting techniques to analyse “sun-as-a-star” p-mode data. This ...

Non-verbal communication (NVC) plays a major role in various aspects of human life (Andersen, 2004; Cameron, 2001; Johnstone, 2008). Children learning their first language come to realize non-verbal communication as their socialization process takes place (Fletcher & German, 1990; Ingram, 1996; Owens, 2001). However, most EFL learners may have little exposure to these non-verbal aspects of comm...
