Curve sawing is a primary log breakdown process that incorporates gang-saw technology to allow two-sided cants from logs with sweep to be cut parallel to the log surface or log axis. Since curve-sawn logs with sweep are cut along the grain, the potential for producing high quality straight-grain lumber and cants increases, and strength, stiffness, and dimensional stability are maximized. Presen...

The Voronoi diagram is an important data structure in computational geometry. Given n sites in the plane, the Voronoi diagram partitions the plane into n regions. The region of a site p consists of all those points that lie closer to p than to any of the other sites. For a survey on Voronoi diagrams and their applications we refer to Aurenhammer [1]. A generalization of the sweep line method of...

We present provably efficient parallel algorithms for sweep scheduling, which is a commonly used technique in Radiation Transport problems, and involves inverting an operator by iteratively sweeping across a mesh from multiple directions. Each sweep involves solving the operator locally at each cell. However, each direction induces a partial order in which this computation can proceed. On a dis...

Fishery-independent surveys provide valuable information about trends in population abundance for management of commercially important fish stocks. A critical component the relationship catches survey to size a stock is catch efficiency gear. Using general hierarchical model we estimated relative chain sweep rockhopper used by Northeast Fisheries Science Center bottom trawl from paired-gear exp...

In this study we tested an alternative method for collecting mosquito larvae called the sweep net catch method and compared its efficiency to that of the traditional dip method. The two methods were compared in various water bodies within Kruger National Park and Lapalala Wilderness area, South Africa. The sweep net catch method performed 5 times better in the collection of larvae and equally a...

Self-fertilization is generally seen to be disadvantageous in the long term. It increases genetic drift, which subsequently reduces polymorphism and the efficiency of selection, which also challenges adaptation. However, high selfing rates can increase the fixation probability of recessive beneficial mutations, but existing theory has generally not accounted for the effect of linked sites. Here...

We study improvements of standard and multilevel Monte Carlo methods for point evaluation of the cumulative distribution function (failure probability) applied to porous media two-phase flow simulations with uncertain permeability. In an injection scenario with sweep efficiency of the injected phase as quantity of interest, we seek the probability that this quantity of interest is smaller than ...

Summary: We present a new optical frequency domain reflectometry technique which permits high frequency sweep repetition rates without sacrificing range. This technique could thus be adapted for remote and distributed acoustic sensing over long
