Dynamic performance of small diameter tunnel thrusters.
The transient response of a small tunnel thruster is studied for step changes in applied voltage to the thruster motor. Previous work on positioning Remotely Operated Vehicles with a ducted propeller had shown that lags in the thruster response caused limit cycling in the vehicle's behavior. These …

Relating diameter and mean curvature for varifolds
… weight measure is compact, then the intrinsic diameter with respect to the support of the weight measure is estimated in terms of the generalized mean curvature. This estimate is in analogy to the diameter control for closed connected manifolds smoothly immersed in some Euclidean space of Peter …

Peg Solitaire on Trees with Diameter Four
… for the solvability for all trees with diameter four. We also give the maximum number of pegs that can be left on such a graph under the restriction that we jump whenever possible.</p>

A description of Virginia pine diameter distributions
… objective of a mathematical expression of diameter distributions in natural stands of Virginia pine, several constructive conclusions and recommendations are possible. All of them are offered with the perspective that research in the interest of advancing growth and yield techniques in …

Gas distribution in shallow large diameter packed beds
… uniform distribution of gas and liquid in large diameter packed columns to maintain mass transfer efficiency on scaling up. This work presents measurements and methods of evaluating maldistributed gas flow in packed columns. Little or no previous work has been done in this field. A gas …

New structural systems in small-diameter round timber
Trees, when used as structural elements in their natural, round form, are up to five times stronger than the largest piece of dimensioned lumber they could yield. Additionally, these whole-timbers have a lower effective embodied carbon than any other structural material. When combined into …

Diameter, Girth And Other Properties Of Highly Symmetric Graphs
… have a high degree of symmetry. In the degree-diameter problem, we consider the question of finding asymptotically large graphs of given degree and diameter. We improve a number of the current best published results in the case of Cayley graphs of cyclic, dihedral and general groups. In the …

Flow boiling of R134a in vertical mini-diameter tubes
… visualization of R134a in small to mini/micro-diameter tubes. The experimental facility was first designed and constructed by X. Huo (2005) with the contribution of L. Chen (2006). In the present study, the experimental facility was upgraded by changing the heating system from AC to DC heating …

Methods for modeling whole stem diameter growth and taper
… and taper to be the rate of narrowing in diameter given a tree form. Ormerod's stem profile model was selected as the basic model since its parameters were readily interpretable in terms of Gray's taper and form definitions. Two stage modeling procedures were used to relate individual tree …

Investigation of carburization extent from the inner diameter (ID) of ethylene furnace tubes using non-destructive examination (NDE) applied on the outer diameter (OD)
This research project is to investigate the possibility of measuring the depth and location of carburization and metal dusting on the inside of ethylene pyrolysis tubes using nondestructive tools applied to the outer surface. A carburization test was conducted in a specially designed and …

The mechanical design aspects of a small diameter vascular prosthesis
Failure of medium to small diameter vascular grafts is believed to be in part due to the compliance mismatch between the native artery and the implanted graft. Consequently, designers are examining the use of more compliant materials for their manufacture. Ether free polyurethanes are currently …

High porosity electrospun scaffolds for small diameter vascular graft applications
Porosity, pore size and pore interconnectivity have been shown to be critical factors for cellular infiltration into vascular grafts. While electrospinning has been shown to produce many promising characteristics for the fabrication of vascular graft scaffolds, it has yet to create sufficient …
