A Practical Test Method for Mode I Fracture Toughness of Adhesive Joints with Dissimilar Substrates

Description: A practical test method for determining the mode I fracture toughness of adhesive joints with dissimilar substrates will be discussed. The test method is based on the familiar Double Cantilever Beam (DCB) specimen geometry, but overcomes limitations in existing techniques that preclude their use when testing joints with dissimilar substrates. The test method is applicable to adhesive joints where the two bonded substrates have different flexural rigidities due to geometric and/or material consi… more

Smart Onboard Inspection of High Pressure Gas Fuel Cylinders

Description: The use of natural gas as an alternative fuel in automotive applications is not widespread primarily because of the high cost and durability of the composite storage tanks. Tanks manufactured using carbon fiber are desirable in weight critical passenger vehicles because of the low density of carbon fiber. The high strength of carbon fiber also translates to a weight reduction because thinner wall designs are possible to withstand the internal pressure loads. However, carbon fiber composites are… more

Automatic Scheme Selection for Toolkit Hex Meshing

Description: Current hexahedral mesh generation techniques rely on a set of meshing tools, which when combined with geometry decomposition leads to an adequate mesh generation process. Of these tools, sweeping tends to be the workhorse algorithm, accounting for at least 50% of most meshing applications. Constraints which must be met for a volume to be sweepable are derived, and it is proven that these constraints are necessary but not sufficient conditions for sweepability. This paper also describes a new a… more

Jet calorimetric trigger

Description: The problem in triggering on jets in hadron colliders is that the largest background in the trigger is also a jet. Therefore, we must strive to trigger as incisively as possible. Since the basic physics resides in the transverse momentum, Pt, of the jet, this means to trigger with as sharp a Pt discriminant as possible. The basic problem is different for electrons or photons, where the backgrounds are typically jets. For heavy quarks, like b, the backgrounds are mismeasured secondary vertices. … more

Physics Analyses in the Design of the HFIR Cold Neutron Source

Description: Physics analyses have been performed to characterize the performance of the cold neutron source to be installed in the High Flux Isotope Reactor at the Oak Ridge National Laboratory in the near future. This paper provides a description of the physics models developed, and the resulting analyses that have been performed to support the design of the cold source. These analyses have provided important parametric performance information, such as cold neutron brightness down the beam tube and the va… more

Recent QCD Results from SLD

Description: We present selected results on strong interaction physics from the SLD experiment at the SLAC Linear Collider. We report on several new studies of 3- and 4-jet hadronic Z{sup 0} decays, in which jets are identified as quark, antiquark or gluon. The 3-jet Z{sup 0} --> b anti-bg rate is sensitive to the b-quark mass; prospects for measuring m{sub b} are discussed. The gluon energy spectrum is measured over the full kinematic range, providing an improved test of QCD and limits on anomalous b an… more

Tetrahedral Element Shape Optimization via the Jacobian Determinant and Condition Number

Description: We present a new shape measure for tetrahedral elements that is optimal in the sense that it gives the distance of a tetrahedron from the set of inverted elements. This measure is constructed from the condition number of the linear transformation between a unit equilateral tetrahedron and any tetrahedron with positive volume. We use this shape measure to formulate two optimization objective functions that are differentiated by their goal: the first seeks to improve the average quality of the te… more

Multitasking TORT Under UNICOS: Parallel Performance Models and Measurements

Description: The existing parallel algorithms in the TORT discrete ordinates were updated to function in a UNI-COS environment. A performance model for the parallel overhead was derived for the existing algorithms. The largest contributors to the parallel overhead were identified and a new algorithm was developed. A parallel overhead model was also derived for the new algorithm. The results of the comparison of parallel performance models were compared to applications of the code to two TORT standard test p… more

Performance of the IBM General Parallel File System

Description: Experimental performance analysis is a necessary first step in input/output software tuning and real-time environment code performance prediction. We measure the performance and scalability of IBM's General Parallel File System (GPFS) under a variety of conditions. The measurements are based on a set of benchmark codes that allow us to vary block sizes, access patterns, etc., and to measure aggregate throughput rates. We use the data to give performance recommendations for application developme… more

Small Business Innovation Research Program

Description: In 1982, the Small Business Innovation Development Act (P.L. 97-219) established small business innovation research (SBIR) programs within the major federal research and development (R&D) agencies. The intent of the effort was to increase government funding of small, high technology companies for the performance of R&D with commercial potential. Each federal department with an R&D budget of $100 million or more is required to set aside part of this amount to finance the SBIR activity. From its … more

Two-Element Phased Array of Anti-Guided Vertical-Cavity Lasers

Description: We demonstrate for the first time anti-guided coupling of two adjacent vertical-cavity surface-emitting lasers (VCSEL's), obtaining a 1-by-2 phase-locked array at 869 nm. The lateral index modification required for anti-guiding is achieved by a patterned 3-rim etch performed between two epitaxial growths. In contrast with prior evanescently coupled VCSEL's, adjacent anti-guided VCSEL's can emit in-phase and produce a single on-axis lobe in the far field. Greater than 2 mW of in-phase output pow… more

Volume Decomposition and Feature Recognition for Hexahedral Mesh Generation

Description: Considerable progress has been made on automatic hexahedral mesh generation in recent years. Several automatic meshing algorithms have proven to be very reliable on certain classes of geometry. While it is always worth pursuing general algorithms viable on more general geometry, a combination of the well-established algorithms is ready to take on classes of complicated geometry. By partitioning the entire geometry into meshable pieces matched with appropriate meshing algorithm the original geom… more
