The use of orthotic heel lifts is proposed in many cases of Achilles tendon disorders as a first-line or conservative treatment. The use of heeled shoes induces a plantar flexion of the ankle joint with a consequent decrease in the tension forces acting onto the triceps surae. The question to address is how high must the heel be? Gait cycle using 1 cm- and 2 cm-high heel lifts was examined. Eac...

As a generalization of the 2D Fourier transform (2D FT) and 2D fractional Fourier transform, the 2D nonseparable linear canonical transform (2D NsLCT) is useful in optics and signal and image processing. To reduce the digital implementation complexity of the 2D NsLCT, some previous works decomposed the 2D NsLCT into several low-complexity operations, including 2D FT, 2D chirp multiplication (2D...

Introduction The Department of Defense conducts syndromic surveillance of health encounter visits of Military Health System (MHS) beneficiaries. Providers within the MHS assign up to 10 diagnosis codes to each health encounter visit. The diagnosis codes are grouped into syndrome and sub-syndrome categories. On October 1, 2015, the Health and Human Services-mandated transition from ICD9-CM to IC...

We describe the implementation of a fluid dynamical benchmark on the 2048 vector node CM-200 parallel computer and on the 1024-node CM-5 computer. The benchmark, the Shallow Water Equations, is frequently used as a model for both oceanographic and atmospheric circulation. We describe the steps involved in implementing the algorithm on the two Thinking Machines Corporation computers and we provi...

ABOUT THE COVER " I t isn't up to the painter to define the symbols, " said Pablo Picasso when asked to explain his celebrated mural, Guernica. " ….The public who look at the picture must interpret the symbols as they understand them. " Picasso himself did not know what the work would turn out to be when he was commissioned to paint the center-piece for the Spanish Pavilion of the 1937 World's ...
