A remarkable record of early arc volcanism in the Izu–Bonin–Mariana (IBM) arc is exposed in and around the Bonin Islands, an uplifted segment of the IBM forearc. New Ar/Ar dating results imply that the boninitic volcanism on Chichijima Island occurred in a brief period during Eocene time, between 46–48 Ma. A slightly younger volcanic succession is identified along the Bonin Ridge, including 44....

We will show that the ADM 3+1 evolution equations, for a zero shift vector, arise naturally from the equations for the second variation of arc-length.

Sensing plays a key role in automating and controlling welding processes. Although arc light sensing has advantages over through-the-arc sensing for arc length control and seam tracking, the current technology relies on experimental data and lacks theoretical foundation. To improve measurement accuracy, this work addresses the theoretical foundation for arc light sensing. A theoretical model ha...

The purpose of this study was to determine the maximum proton kinetic energy required to treat a given percentage of patients eligible for stereotactic radiosurgery (SRS) with coplanar arc-based proton therapy, contingent upon the number and location of gantry angles used. Treatment plans from 100 consecutive patients treated with SRS at the University of Wisconsin Carbone Cancer Center between...

This study is an attempt to create a canonical representation scheme for finite length strings to simplify the study of the theory behind different classes of patterns and to ease the understanding of the underlying separability issues. This could then be used to determine what kinds of techniques are suitable for what class of separability (linear, multi-linear or non-linear). This representat...

Abstract: In order to improve the frame synchronization performance of the adaptive length frame transmission system, a frame synchronization scheme is proposed. The scheme considers the false loss probability relating to the bit error rate and the false alarm probability relating to the model of synchronous header are considered synthetically. Then the performance formulas of general frame syn...

Gas tungsten arc welding (GTAW) is the primary process for precision joining of metals due to its capability for accurate control of heat input. As a close relative and modification of GTAW, plasma arc welding (PAW) has higher energy density and can penetrate thicker workpieces while maintaining the desired capability for accurate control of heat input. In order to produce quality welds consist...

4 We consider the problem of deciding whether a given network with integer capacities has two 5 feasible flows x and y with prescribed balance vectors such that the arcs that carry flow in x are 6 arc-disjoint from the arcs that carry flow in y. This generalizes a number of well-studied problems 7 such as the existence of arc-disjoint out-branchings B s , B + t where the roots s, t may be the s...
