This paper describes RHALE, a multi-material arbitrary Lagrangian-Eulerian (MMALE) shock physics code. RHALE is the successor to CTH, Sandia’s 3-D Eulerian shock physics code, and will be capable of solving problems that CTH cannot adequately address. We discuss the Lagrangian solid mechanics capabilities of RHALE, which include arbitrary mesh connectivity, superior artificial viscosity, and im...

We introduce a parallel implementation of the Simple Linear Iterative Clustering (SLIC) superpixel segmentation. Our implementation uses GPU and the NVIDIA CUDA framework. Using a single graphic card, our implementation achieves speedups of 10x∼20x from the sequential implementation. This allow us to use the superpixel segmentation method in real-time performance. Our implementation is compatib...

syntax tree of a program. Data flow analysis updates a global state when the abstract syntax tree matches rules in the specification. This technique allows scripting of simple analysis checks. Specification languages are directly applicable to my analysis work. My framework already uses a simple specification language similar to SLIC to specify preand postmemory conditions for functions being a...

In this paper, we propose a new method of image segmentation, named SLICAP, which combines the simple linear iterative clustering (SLIC) method with the affinity propagation (AP) clustering algorithm. First, the SLICAP technique uses the SLIC superpixel algorithm to form an over-segmentation of an image. Then, a similarity is constructed based on the features of superpixels. Finally, the AP alg...

A scanning liquid-filled ionization chamber electronic portal imaging device (SLIC-EPID) and extended dose range (EDR2) films were used to evaluate transmitted dose profiles for homogeneous and inhomogeneous phantoms. Calibrated ionization chamber measurements were used to convert the pixel values acquired from the electronic portal images to dose. Because SLIC-EPID was developed to have a unif...

Text segmentation is an important step in the process of character recognition. In literature, there have been numerous methods that work very well in practical applications. However, when an image includes strong noise or surface reflection distraction, accurate text segmentation still faces many challenges. Observing that the stroke width of text is stable and significantly different from tha...

BACKGROUND AND OBJECTIVES Until the advent of singleincision laparoscopic surgery, few advances were aimed at improving cosmesis with laparoscopic cholecystectomy. Criticisms of the single-incision laparoscopic surgery technique include a larger incision and increased incidence of wound-related complications. We present our initial experience with a novel technique aimed at performing strategic...

STUDY DESIGN  Interobserver and intraobserver reliabilityObjective: To measure and compare the interobserver and intraobserver reliability of the cervical spine injury severity score (CSISS), the subaxial injury classification (SLIC) and severity scale, and the Allen-Ferguson system in patients with subaxial cervical spine injuries presenting to the emergency department. METHODS  Five examine...

The Simple Network Management Protocol (SNMP) has been around for more than a decade and is supported by most network devices and end systems. Despite this success, there is still a lack of simple to use network management applications. This paper describes the design of an SNMP management tool called scli which provides an easy and efficient to use SNMP command line interface. The software arc...
