Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

We have studied (001) surface terminated cerium oxide nanoparticles grown on a ruthenium substrate using physical vapor deposition. Their morphology, shape, crystal structure, and chemical state are determined by low-energy electron microscopy and micro-diffraction, scanning probe microscopy, and synchrotron-based X-ray absorption spectroscopy. Square islands are identified as CeO2 nanocrystals...

We justify discrete and asymptotic approximations for the radiative-conductive heat transfer problem in a system of heat-conductive rods with square cross-section separated by vacuum layers placed box. obtain error estimates order $$ O\left(\sqrt{\varepsilon }/\lambda \right) O\left(\sqrt{\varepsilon}\right), where ε is length rod side, λ conductivity.

The oil film generation of a U-cup rod seal and the thickness on after outstroke were analyzed analytically, numerically, experimentally. sealing system consists an unmodified, commercially available U-cup, polished rod, mineral oil. inverse theory hydrodynamic lubrication (IHL) elastohydrodynamic (EHL) model—both based Reynolds equation for thin lubricating films—were utilized to simulate gene...

We derive a scaling relationship for the mean square rotation rate of rods with lengths in the inertial range in turbulence: ∝ l(-4/3). We present experimental measurements of the rotational statistics of neutrally buoyant rods with lengths 2.8<l/η<72.9, and find that the measurements approach the predicted scaling. The approach to inertial range scaling is shown to be more complex t...

(i) Solve for u (x, y, t) subject to an initial condition u (x, y, 0) = 100. (ii) Find the smallest eigenvalue λ and the first term approximation (i.e. the term with e−λκt). (iii) For fixed t = t0 ≫ 0, sketch the level curves u = constant as solid lines and the heat flow lines as dotted lines, in the xy-plane. (iv) Of all rectangular plates of equal area, which will cool the slowest? Hint: for ...
