Reports on a study done by the University of Westminster and financed by the Association of Soft Tissue Paper Manufacturers finding that hot air dryers increased bacteria on hands more than 500%. 2.

Modern electrical dryers are often equipped with end-ofcycle alarms, making their use more efficient and reducing the need for periodic monitoring. We believe that lowerincome households as well as ecologically aware consumers, drying their laundry on a clothesline, could benefit from a similar mechanism. Such an alarm must be simple to use, compatible with existing systems and low-cost. This w...

This problem was suggested by Bradley Klee. For the related case of one cylinder rolling inside another, see [1]. When one cylinder is directly above the other, we define the line of contact of the lower cylinder, 1, with the horizontal plane to be the z-axis, at x = y = 0. Then, the condition of rolling without slipping for the lower cylinder is that when it has rolled (positive) distance x1, ...

An algorithm of finding numerical solutions of pulsar equation is presented which is essentially different from the one used in the pioneering paper by Contopoulos, Kazanas & Fendt. The problem of finding the solutions was reduced to finding expansion coefficients of the source term in a base of orthogonal functions on the unit interval by minimizing a multi-variable mismatch function defined o...

Models of multi-RAID storage systems, implemented on modern zoned disks, are simplified by using an approximation for the seek distance that assumes that the number of sectors per track varies linearly with the cylinder number. Results obtained in this way have matched well against simulation, but the relationship of the number of sectors per track against cylinder number has turned out to be r...

This paper describes an evaluation of a neural network technique for modelling fuel spray penetration in the cylinder of a diesel internal combustion engine. The model was implemented using a multi-layer perceptron neural network. Two engine operating parameters were used as inputs to the model, namely injection pressure and in-cylinder pressure. Spray penetration length were modelled on the ba...
