Abstract This paper applies a new approach to the identification of discourses, based on Multiple Correspondence Analysis (MCA), study discourse variation over time. The MCA keywords deals with major issue use identify discourses: allocation individual multiple discourses. Yet, as this demonstrates, also allows us observe in prevalence discourses texts patterns keyword co-occurrence. Metadata c...

Authors are requested to select key words from the following list. You may use plurals and adjectives for combinations like absolute pupillary response, centrifugal optic nerve, inter blobs, etc. If key words are needed which do not appear in this list, please underline them. For animal classification the Latin nomenclature should be used. p-mechanism A-scan a-wave aberration absolute absorptio...

Fracture in thin films is normally constrained by the substrates. If the substrate creeps, however, the constraint will be lost over time. This paper presents a two-dimensional model for channel cracks in an elastic film on a viscous layer, and implements an extended finite element method to evolve the displacement field and the stress intensity factor with relatively coarse meshes. Solutions a...

Plastic liquids, also known as Bingham liquids, retain their shape when loads are small, but flow when loads exceed a threshold. We discovered that plastic liquid films coated on elastomers develop wavy patterns under cyclic loads. As the number of cycles increases, the wavelength of the patterns remains unchanged, but the amplitude of the patterns increases and then saturates. Because the patt...

We discuss the “soft-ratcheting” algorithm which generates targeted stochastic trajectories in molecular systems with scores corresponding to their probabilities. The procedure, which requires no initial pathway guess, is capable of rapidly determining multiple pathways between known states. Monotonic progress toward the target state is not required. The soft-ratcheting algorithm is applied to ...

We present a fabrication approach for the production of micromachined biodegradable microstructures, and illustrate its application in two areas: biodegradable microneedles for transdermal drug delivery, and biodegradable ratcheting surgical ties for blood vessel surgery. We fabricated solid polymer microneedles out of polyglycolide, polylactide and their copolymer using a micromolding techniqu...

A design project was carried out which began with the study and critique of office paper attachment systems, such as paperclips and staples. A set of criteria for an ideal system of attachment was then developed. This led to the design of an improved system and the manufacture of a prototype to prove the concept behind it. The concept that was developed and pursued was a ratcheting clip. The ra...
