1959 SUMMARY A method is given for representing the results of wind-tunnel tests of fan wings in a non-dimensional form suitable for the analysis of transition mQtion3. The procedure takes into account the effect on power requirements of variation of thrust engine loading in relation to that of the fan. As an example, results are displayed of tests of a rectangular wing of aspect ratio I with f...

Requxrements are discussed for an Iunpllfier slutable for subsonic and supersonx tdx&?nce work nxth hot xlres. Such an empllfier needs to have a constant gain at low frequencies, ad a gain rlslng In proportion to frequency at h& frequenmes, UI order to compensate for the the-1 lag of tho hot vzrc. A fairly sharp cutoff 1s required at the high frequency end, and it is desirable that this cutoff ...

Dispersing billiards introduced by Sinai are uniformly hyperbolic and have strong statistical properties (exponential decay of correlations and various limit theorems). However, if the billiard table has cusps (corner points with zero interior angles), then its hyperbolicity is nonuniform and statistical properties deteriorate. Until now only heuristic and experiments results existed predicting...

A clear understanding of the impacts of forest practices on long-term soil productivity is required to maintain the productivity of forest soils while forests continue to be managed for timber production. Although current regulations governing soil conservation in British Columbia are partially based on historic and ongoing research, there are few clear and unambiguous long-term results. The ne...

We attempt to correlate all of the available solar-neutrino capture-rate data with the strong magnetic fields these neutrinos encounter in the solar interior along their Earth-bound path. We approximate these fields using the (photospheric, magnetograph-measured) surface magnetic flux from central latitude bands, time delayed to proxy the solar interior. Our strongest evidence for anticorrelati...
