219-235, ASME winter meeting, Anaheim, CA, Nov. 1998. ABSTRACT A new finite element approach to sandwich shells is proposed. It uses existing shell finite elements formulated for homogeneous shells. The “sandwich” nature of the problem is hidden from the main finite element program. Based on several assumptions the proposed homogenization procedure calculates stress increments in a homogeneous ...

A successful photodynamic therapy (PDT) requires a specific photosensitizer, oxygen and light of a specific wavelength and power. Today photodynamic therapy (PDT) is administered to patients with light-emitting diode (LED) panels. These panels deliver a non-uniform light distribution on the human body parts, as the complex human anatomy is not a flat surface (head vertex, hand, shoulder, etc.)....

Self-assemblyings of surfactant-encapsulated Wells-Dawson polyoxometalates (SEPs) nanobuilding blocks in butanone and esters yielded supramolecular gels showing thermo and photo responsive properties. The gels can be further polymerized if unsaturated esters were used and subsequently electrospinned into nanowires and non-woven mats. The as-prepared non-woven mats have a Young's modulus as high...

A permutor design for woven convolutional encoders with outer warp is introduced. All warp permutors are considered jointly, and for the overall design an approach similar to that of higher order separations for serially concatenated convolutional codes is applied. We present a bound on the minimum distance of a code generated by a woven convolutional encoder with outer warp and designed row pe...

Woven coronary artery disease is a rare congenital malformation characterized by dividing coronary arteries into thin channels, which then join distally (1). This morphology has been previously described in both right and left coronary arteries and may be associated with acute coronary syndromes. Probably most of these anomalies are misdiagnosed by many clinicians. We report a case of right wov...

We present a technique for creating procedurally the texture of the twists of thread. The procedure is designed to support variations in appearance due to tightness of twist, thickness of the bundles twisted together and the roughness of the fibers. The procedural texture of the twist is further shaded to give it the appearance of a typical facet of thread that is visible on woven clothes. We d...

Computational methods for modeling complex three-dlmenaional woven structure\ are reviewed and software tools for automated model construction are described. The tools make use of image processing, geometric and attribute modeling, automated discretization, and efficient solvers. The discretization techniques control me\h periodicity and volume fraction errors of meshed constituents due to appr...

background: musculoskeletal disorders (msds) are among important health problems in working population. because of performing difficult physical activities, hand-woven shoe-sole makers are at risk of developing various types of msds. objective: to determine the prevalence of musculoskeletal symptoms in different body areas of hand-woven shoe-sole makers, assess workers′ postures and workstation...
