Generation and optimization of spacing fields
… to perform adaptive refinement or smoothing a spacing field is needed to define the desired edge sized in mesh. The objectives of this research are to generate spacing fields from existing CFD solutions and optimize this spacing information for efficient use by programs to perform adaptive …

Spacing innovation and learning in design organizations
… and expand existing theories, to reflect on the "spacing" of the three design organizations under study and to contribute to the outline of this interdisciplinary emerging field of research.

Law-in-spacing : geographies of territorialization and resistance
… territories highlighted a process of law-in-spacing, a process by which the private law principles of common law became increasingly visible in the context of these traditionally Civil law populations. I also show that the common law had specific and unforeseen consequences for these …

Corn residue, tillage, and row spacing effects on soybean
… before soybean planting. In addition, row spacings of 38 or 76 cm and effect of foliar fungicide were evaluated within residue-tillage treatments. Across two years at Urbana, yield response to combinations of row spacing and tillage responded similarly in standing and chopped residue …

Within-row spacing effect on individual corn plant yield
… shown that modest non-uniformity of corn plant spacing has small, negative effects on grain yield. The extent to which this influence of distance to adjoining plants is due to compensatory yield adjustments is not known. In 2011 and 2012, high density stands in 76 cm rows were hand thinned to 74 …

Vehicle Axle Detection and Spacing Calibration Using MEMS Accelerometer
… vehicle classification based on axle count and spacing was designed, tested, and applied to the pavement. Vehicle-pavement interaction was collected by the vibration sensor while vehicle axle count and spacing were calibrated later. Collected vibration data also used to analyze the pavement …

Economic Analysis of Sunflower (Helianthus annuus) Spacing in East Texas
<p>Two experiments were conducted on spacing of <em>Helianthus annuus</em> in East Texas to determine the spacing treatment that produces the greatest revenue per m<sup>2</sup>. The experiments had four spacing treatments of 8 × 15 cm, 15 × 15 cm, 23 × 23 cm, and 30 × 30 cm. Three different …

An optimization approach to well spacing for gas storage reservoirs
… view to apply it to the problems of optimum well spacing. An equilateral grid system has been employed to enable uniform well spacing for any number of wells. A numerical model has been developed on an IBM 360 - Model 50 computer, which simulates the pressure and saturation transience in the …

Productivity and biomass partitioning in 20-year Black cottonwood at variable spacing
… were to investigate the effects of different spacing treatments on aboveground biomass production, bark, sapwood and heartwood ratios and the branching ratio in 20-year old Black cottonwood (Populus balsamifera L. ssp. trichocarpa (Torr. & A. Gray ex Hook.) Brayshaw) experimental plantation …

String Stable Constant-Spacing Platoon with Robustness to Communication Delays and Cutoff
… dissertation develops a string stable, constant-spacing control strategy for connectedautonomous vehicle networks with robustness to communication delays and cutoff. It is well-known that decentralized constant-spacing strategies cannot achieve string stability, which requires the error to …

Density and spacing properties of some families of non-standard ternary representations
In this dissertation, we study a family of non-standard digital representations in base 3. Let A be an index set such that A={0,u1,u2}, where u1 is equivalent to 1 (mod 3) and u2 is equivalent to 2 (mod 3). We study the set of integers which can be written as \sum_{i=0}^{\infty}\epsilon_i 3^i, …

Yield response of soybean to planting date and row spacing in Illinois
… Recent studies of planting date and row spacing have been limited in geographic scope, and few of these have included both factors together. Studies combining these factors, and seeding rate, were conducted during 2010 and 2011 at six Illinois locations. Four planting dates and two row …

Basal Area Growth and Crown Dynamics in a Loblolly Pine Spacing Trial
… pine (Pinus taeda L.) were investigated. A spacing trial established on the low Appalachian Piedmont and Atlantic Coastal Plain provided the data for the investigation. Test plots were planted at densities ranging from 303 to 2723 stems per acre, and at various rectangular and square …

Pinching and Spacing Effects on Cut Sunflower (Helianthus annuus) Production in East Texas
<p>Three experiments evaluated pinching and spacing on <em>Helianthus annuus </em>in East Texas to determine their effects on growth and development. Experiment 1 was designed to determine the effects of pinching nodes 1, 2, 3, or 4 on ‘Pro Cut Gold’ sunflowers. Results from experiment 1 showed …

Application of artificial intelligence techniques to well spacing optimization in fractured tight reservoirs
Well spacing optimization is critical to the success of any hydrocarbon field development particularly unconventional fields and significantly affects the economic performance of oil and gas production operations. Oil and gas field operators over the years have resorted to field trials, …
