Through a sampling survey of the results physical fitness test students Guilin Institute Aerospace Industry in 2018, using analysis variance research method, five variable indicators surveyed were analyzed, and changes during three years university studied. The show that college, has been increasing year by year, but growth rate declining, difference is mainly due to their own high body mass in...

Abstract We use hyperbolic wavelet regression for the fast reconstruction of high-dimensional functions having only low dimensional variable interactions. Compactly supported periodic Chui–Wang wavelets are used tensorized basis. In a first step we give self-contained characterization tensor product Sobolev–Besov spaces on d -torus with arbitrary smoothness in terms decay such coefficients. sec...
