minimum inertia balance w eight
the optimum shape of balance weights is determined, using two different criteria. according to one, one of the balance weights should have minimum size. while the other requires that the mass moment of inertia about the axis of rotation should be minimum. in the second case, the calculus of variation is used to determine the optimum shape. graphs are presented to enable designers to find the di...
متن کاملW and Z Physics
The electroweak theory elegantly combines the electromagnetic and weak forces, explaining a wide range of interactions using a gauge theory with just three parameters. The theory predicted the W and Z weak gauge bosons before they were directly observed in 1983, and its detailed predictions of W and Z boson properties have been tested to such precision that they now serve as probes for new part...

متن کاملThe neurology of Attention Deficit/Hyperactivity Disorder problemy neurologiczne w ADHD
ADHD is a brain based disorder with structural and functional abnormalities in widespread but specific areas of the brain. The most significant and consistent structural imaging findings include smaller total brain volumes, and reduced volumes in the right frontal lobe, right parietal cortex, caudate nucleus, cerebellar hemispheres, and posterior-inferior lobules of the cerebellar vermis. ADHD ...

We prove that the minimum number (asymptotically) of monochromatic Schur triples that a 2-coloring of [1, n] can have is n 2 22 + O(n).: In a fascinating invited talk at the SOCA 96 combinatorics conference organized by Bill Chen, Ron Graham proposed (see also [GRR], p. 390): Problem ($100): Find (asymptotically) the least number of monochromatic Schur triples {i, j, i+ j} that may occur in a 2...
