background: various variance reduction techniques such as forced detection (fd) have been implemented in monte carlo (mc) simulation of nuclear medicine in an effort to decrease the simulation time while keeping accuracy. however most of these techniques still result in very long mc simulation times for being implemented into routine use. materials and methods: convolution-based forced detectio...

background the forced oscillation technique (fot) is a non-invasive means of measuring respiratory resistance and reactance. we tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in fot parameters than a supraglottic airway device (sgd). methods forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tu...

‎a numerical technique based on the collocation method using legendre multiwavelets are‎‎presented for the solution of forced duffing equation‎. ‎the operational matrix of integration for‎‎legendre multiwavelets is presented and is utilized to reduce the solution of duffing equation‎‎to the solution of linear algebraic equations‎. ‎illustrative examples are included to demonstrate‎‎the validity...

objective(s): in this study the effect of crocin, a carotenoid isolated from saffron, on malathion (an organophosphate insecticide) induced depressive- like behavior in subacute exposure was investigated. moreover the molecular mechanism of malathion induced depressive- like behavior and its decreasing effect on the level of brain derived neurotrophic factor (bdnf) in rat hippocampus and cerebr...

Razzaq et al, 2005 reported that the Assistment system was causing students to learn at the computer but we were not sure if that was simply due to students getting practice or more due to the "intelligent tutoring" that we created and force students to do if they get an item wrong. Our survey indicated that some students found being forced to do scaffolding sometimes frustrating. We were not s...

Since the implementation of the first HVDC thyristor valve at Eel River (Canada) in the early 1970’s, HVDC transmission has experienced tremendous growth. As power systems grow and become more integrated, interconnections to neighboring ac systems are becoming increasingly necessary to enhance stability, security of supply, flexibility and for other economic benefits. Primarily for stability re...

THE TECHNIQUE OF DETERMINATION OF STRUCTURAL PARAMETERS FROM FORCED VIBRATION TESTING Wai Fan Tsang This thesis details the results of an investigation into a technique for determination of "useful" structural parameters from forced vibration testing. The implementation of this technique to full scale civil engineering structures was achieved by several developments in the experimental and comp...

In the Set Coincidence Game G(V, W), two players alternately choose elements not previously chosen from a finite, nonempty set V, and W is a given family of nonempty subsets of V (the ‘winning sets’). The winner is that player who first adds an element to the set of ‘chosen’ elements 5, so that S E W. This game is closely related to and generalizes Ringeisen’s Isolation Game on graphs. We devel...

This paper examines whether the forced resignation of managers of Dutch football teams leads to an improvement in the results. We find by analysing 12 years of football in the highest Dutch league that forced resignations are preceded by declines in team performance and followed by improvements in performance. However, the improvement in performance after appointing a new manager does not excee...

O important decision firms must make is to select the product line (characteristics and number of products) to offer consumers. This paper explores the effect of the interaction between consumer evaluation costs and pricing on the optimal product line length to offer consumers. Before deciding to buy a product among all products offered, a consumer learns the product line length. Given the prod...
