The Application of Reliability-Based Design Factors In Stress Corrosion Cracking Evaluations

Description: First-order reliability methodology (FORM) is used to develop reliability-based design factors for deterministic analyses of stress corrosion cracking. The basic elements of FORM as applied to structural reliability problems are reviewed and then employed specifically to stress corrosion cracking evaluations. Failure due to stress corrosion cracking is defined as crack initiation followed by crack growth to a critical depth. The stress corrosion cracking process is thus represented in terms of … more

Proton radiation damage in high-resistivity n-type silicon CCDs

Description: A new type of p-channel CCD constructed on high-resistivity n-type silicon was exposed to 12 MeV protons at doses up to 1x1011 protons/cm2. The charge transfer efficiency was measured as a function of radiation dose and temperature. We previously reported that these CCDs are significantly more tolerant to radiation damage than conventional n-channel devices. In the work reported here, we used pocket pumping techniques and charge transfer efficiency measurements to determine the identity and con… more

Inhibition of heregulin expression blocks tumorigenicity and metastasis of breast cancer

Description: The growth factor Heregulin (HRG) is expressed in 30% of breast cancer tumors. HRG induces tumorigenicity and metastasis of breast cancer cells. Our investigation into whether blockage of HRG reduces the aggressiveness of breast cancer cells demonstrated that transfection of MDA-MB-231 with an HRG antisense cDNA suppressed proliferation, tumorigenicity, and metastasis. Blockage of the aggressive phenotype is mediated possibly through inactivation of the erbB signaling pathways and a decrease in… more

Application of a Sixth Order Generalized Stress Function To Determine Limit Loads for Plates with Triangular Penetration Patterns

Description: The capabilities to obtain limit load solutions of plates with triangular penetration patterns using fourth order functions to represent the collapse surface has been presented in previous papers. These papers describe how equivalent solid plate elastic-perfectly plastic finite element capabilities are generated and demonstrated how such capabilities can be used to great advantage in the analysis of tubesheets in large heat exchanger applications. However, these papers have pointed out that alt… more

PDE-based Non-Linear Diffusion Techniques for Denoising Scientific and Industrial Images: An Empirical Study

Description: Removing noise from data is often the first step in data analysis. Denoising techniques should not only reduce the noise, but do so without blurring or changing the location of the edges. Many approaches have been proposed to accomplish this; in this paper, they focus on one such approach, namely the use of non-linear diffusion operators. This approach has been studied extensively from a theoretical viewpoint ever since the 1987 work of Perona and Malik showed that non-linear filters outperform… more

Polarization Studies in Fast-Ion Beam Spectroscopy

Description: In a historical review, the observations and the insight gained from polarization studies of fast ions interacting with solid targets are presented. These began with J. Macek's recognition of zero-field quantum beats in beam-foil spectroscopy as indicating alignment, and D.G. Ellis' density operator analysis that suggested the observability of orientation when using tilted foils. Lastly H. Winter's studies of the ion-beam surface interaction at grazing incidence yielded the means to produce a h… more

UV Laser Conditioning for Reduction of 351-nm Damage Initiation in Fused Silica

Description: This paper describes the effect of 355-nm laser conditioning on the concentration of UV-laser-induced surface damage sites on large-aperture fused silica optics. We will show the effect of various 355-nm laser conditioning methodologies on the reduction of surface-damage initiation in fused silica samples that have varying qualities of polishing. With the best, generally available fused silica optic, we have demonstrated that 355-nm laser conditioning can achieve up to 10x reduction in surface … more
