In the histories of logic and of computer science which mention precursors and pioneers, we often find mention of Leibniz, the great l7th-century mathematician and philosopher, who was one of the first to try to build a mechanical calculator, and who tried to formulate a Mathesis universalis, a sort of scientific language which would permit any two disputants to settle their differences merely ...

The sphere and circumscribing cylinder engraved on Archimedes’ tombstone commemorate his landmark discovery that their volumes and surface areas are related by the same constant ratio 2/3. He discovered the volume relation and many other geometrical results by mechanical balancing. In particular, he found the volume of a cylindrical wedge by introducing the special balancing shown in Figures 1a...

It is shown, that mechanical alignment can be efficient for suprathermally rotating grains, provided that they drift with supersonic velocities. Such a drift should be widely spread due to both Alfvénic waves and ambipolar diffusion. Moreover, if suprathermal rotation is caused by grain interaction with a radiative flux, it is shown, that mechanical alignment may be present even in the absence ...

Find out the relationship between body mass index (BMI) and W.C with disease activity score in AS patients its association clinical characteristics of AS. One hundred five (75 male 30 female) who visited rheumatology medical rehabilitation center Sulaimani city were recorded this cross-sectional study. Disease was measured by ASDAS-ESR hand-held calculator. BMI calculated waist circumference (W...

Perhaps the most obvious myth is that graphics calculators are mainly useful for drawing graphs of functions and hence are not relevant to most mathematics curricula. An hour or two with a modern graphics calculator will quickly dispel this myth. For example, my book, More mathematics with a graphics calculator: Casio cfx-9850G, contains sixteen chapters, only four of which are primarily concer...

The research in this article aims to provide an overview of how to calculate the ROI for E-commerce applications so that this information, and the attached ROI Calculator Tool Template, can be used by organizations to reduce the time in preparing the ROI for a project. Although there is much written about ROI, there is not that much said about how to prepare one specifically for an E-commerce p...
