Shape Calculus for Shape Energies in Image Processing

Author(s)
Gunay Dogan, Ricardo H. Nochetto
Many image processing problems are naturally expressed as energy minimization or shape optimization problems, in which the free variable is a shape, such as a

Performance of BAW Resonators at Cryogenic Temperatures

Author(s)
Eduard Rocas, C. Collado, Jordi Mateu, A Hueltes, J. Verdu, Robert Aigner, James Booth
In this work we go beyond the usual temperature range for commercial applications and explore the functioning of Bulk Acoustic Wave (BAW) resonators down to

Author(s)
Douglas T. Smith, Bartosz K. Nowakowski, Robert F. Cook, Stuart T. Smith, Luis F. Correa
This paper presents the design, construction and performance of a surface- referenced nanoindentation instrument termed a precision nanoindentation platform

Relationship between CTDI values and measured Peak Skin Dose (PSD)

Author(s)
Ronaldo Minniti, Hugo de las Heras Gala, Sean Wilson, Chad Mitchell, Marlene Skopec, Claudia Brunner, Kish Chakrabarti
In this work we relate the CT dose index volume (CTDIvol) readily displayed in all CT units with an actual Peak Skin Dose (PSD) value. Measurements of the CTDI

Many structural defects and strain fields develop during the preparation of thin films and nanostructures, with their origins being at the atomic level1,2

The Metrology of Counting Protein Particles

Author(s)
Dean C. Ripple, Michael J. Carrier, Richard E. Cavicchi, Christopher B. Montgomery, Zhishang Hu
A common degradation pathway for protein-based drugs is the growth of protein aggregates or particles. Counting and characterization of these particles is
