Geometry Modeling for Unstructured Mesh Adaptation

The quantification and control of discretization error is critical to obtaining reliable simulation results. Adaptive mesh techniques have the potential to automate discretization error control, but have made limited impact on production analysis workflow. Recent progress has matured a number of independent implementations of flow solvers, error estimation methods, and anisotropic mesh adaptation mechanics. However, the poor integration of initial mesh generation and adaptive mesh mechanics to typical sources of geometry has hindered adoption of adaptive mesh techniques, where these geometries are often created in Mechanical Computer- Aided Design (MCAD) systems. The difficulty of this coupling is compounded by two factors: the inherent complexity of the model (e.g., large range of scales, bodies in proximity, details not required for analysis) and unintended geometry construction artifacts (e.g., translation, uneven parameterization, degeneracy, self-intersection, sliver faces, gaps, large tolerances be- tween topological elements, local high curvature to enforce continuity). Manual preparation of geometry is commonly employed to enable fixed-grid and adaptive-grid workflows by reducing the severity and negative impacts of these construction artifacts, but manual process interaction inhibits workflow automation. Techniques to permit the use of complex geometry models and reduce the impact of geometry construction artifacts on unstructured grid workflows are models from the AIAA Sonic Boom and High Lift Prediction are shown to demonstrate the utility of the current approach

Reflect and Redefine: Deans’ Perspectives on the Positioning of IS within the Business School

Over the 12 years since the glory days of the dot com and Y2K phenomena at the turn of the last century, IS departments at many colleges and schools of business have suffered significant declines in student enrolments, elimination from core curricula, reduced faculty numbers, and overall a weakened strategic positioning within the business school. Recent AACSB faculty hiring and salary reports indicate that “CIS” is the only discipline which has seen an overall decline in faculty hiring over the past 10 years, in contrast with significant growth in all other disciplines. Many IS departments have been merged with other disciplines, or closed entirely. In contrast, however, a number of IS departments have continued to enjoy significant growth and success. This panel of five current/recent business school deans and members of the IS community will offer their perspectives on the strategic positioning of IS within the business school, and share their recommendations on what IS departments need to do to strengthen their positioning within the business school across the domains of teaching, research and relationships with the broader academic and business communities

The Kepler DB, a Database Management System for Arrays, Sparse Arrays and Binary Data

The Kepler Science Operations Center stores pixel values on approximately six million pixels collected every 30-minutes, as well as data products that are generated as a result of running the Kepler science processing pipeline. The Kepler Database (Kepler DB) management system was created to act as the repository of this information. After one year of ight usage, Kepler DB is managing 3 TiB of data and is expected to grow to over 10 TiB over the course of the mission. Kepler DB is a non-relational, transactional database where data are represented as one dimensional arrays, sparse arrays or binary large objects. We will discuss Kepler DB's APIs, implementation, usage and deployment at the Kepler Science Operations Center

Nuclear Physics Neutrino PreTown Meeting: Summary and Recommendations

In preparation for the nuclear physics Long Range Plan exercise, a group of 104 neutrino physicists met in Seattle September 21-23 to discuss both the present state of the field and the new opportunities of the next decade. This report summarizes the conclusions of that meeting and presents its recommendations. Further information is available at the workshop's web site. This report will be further reviewed at the upcoming Oakland Town Meeting.Comment: Latex, 31 pages. This version has been updated to include final Comments from the working group

Evaluation of Fatigue Management Technologies Using Weighted Feature Matrix Method

Operator fatigue is one of the most prevalent root causes of accidents,both on the highway and in workplaces where heavy equipment is used and 12-hour shifts are employed, such as in the mining industry. In response to thisconcern, a growing number of Fatigue Management Technologies (FMT) arebecoming available to help maintain operator alertness and performance levels bydetecting operator fatigue and interfacing with the operator and/or supervisor toprevent accidents and incidents (Williamson et al., 2005, Barr et al., 2005). Inlight of the numerous competing technologies, the research community, as well asindustry, could benefit from the flexible evaluation tool proposed here. It willassist industries as a whole, and corporations more specifically, in identifying thebest FMT solutions for different work and/or driving situations. This project wasspecifically focused on the needs of operators of heavy equipment in the miningindustry, but could also be of value to other like industries where shift work isnecessary and maintaining high levels of alertness are crucial for ensuringworkplace safety and productivity

Metrology system for measuring mast motions on the NuSTAR mission

A metrology system designed and built for the NuSTAR mission is described. The NuSTAR mission is an orbiting X-ray telescope with a 10 meter focal length. The system consists of two laser pointers mounted rigidly together with a star tracker and the X-ray optics. The focused laser beams illuminates two metrology detectors mounted rigidly with the X-ray detectors. The detectors and optics/lasers are separated by a ∼10 meter deployable (and somewhat flexible) carbon fiber mast. Details about the implementation of the metrology system is discussed in this paper
