2 Principal contact: This year our primary goal was to improve on the performance of our TREC-8 system. In addition to improving the system directly, we worked on a number of tools to aid our development. We continued our work on a tool for automatic scoring of system responses, a “judge” program. We designed a tool for doing regression testing of question answering systems. W...

There is one concept in medicine which is prominent, the symptom. The omnipresence of the symptom seems, however, not to be reflected by an equally prominent curiosity aimed at investigating this concept as a phenomenon. In classic, traditional or conventional medical diagnostics and treatment, the lack of distinction with respect to the symptom represents a minor problem. Faced with enigmatic ...

Annals of Ibadan Postgraduate Medicine. Vol. 14 No. 2, December 2016 56 Prior to the beginning of the 20th Century, infectious diseases accounted for high morbidity and mortality worldwide. The average life expectancy at birth was 47 years (46 and 48 years for men and women respectively) even in the industrialized world. Infectious diseases such as smallpox, cholera, diphtheria, pneumonia, typh...

In this paper, a new method for the balancing of rotor-bearing systems supported on fluid film bearings is proposed. The influence coefficients necessary are calculated using novel simulation called Numerical Assembly Technique. advantages approach quasi-analytical solutions equations motion complex and very low computation times. Technique extended by speed-dependent stiffness damping approxim...

IN addressing the students at the opening of the 1902 session at the Belfast Royal Hospital, then in its final year at Frederick Street, Robert Campbell, who had been appointed Honorary Assistant Surgeon two years earlier, suggested that it might have been more appropriate for one of the senior members of the staff to have undertaken this duty and remarked, "If that address had taken a retrospe...

Let E, F ? Cnxn. If EFiE = 0 for all i N, we give the explicit representation of Drazin inverse block complex matrix (E I 0). We thereby solve a wider kind singular differential equations posed by Campbell [S.L. Campbell, The and systems second order linear equations, Linear & Multilinear Algebra, 14(1983), 195-198].

Academic pursuits are inseparable from the medium within which they take place - life. The lives of medical trainees can present many challenges that are independent of academic demands. Poor psychological health has been found to develop in medical trainees. Can medical educators minimize this decline in well-being? Positive education - learning skills for traditional academia and to foster ha...

SYSTEM R is a variant of the original STRIPS by Fikes and Nilsson (1971) (called forwardchaining, recursive STRIPS in Nilsson [1998]). Briefly speaking, given a conjunction of simple goals, it selects one of them to work on. If there is an action that is executable and will make this simple goal true once executed, then it does this action and then tries to achieve the other simple goals in the...
