The hot embossing of thermoplastic materials, such as polymethylmethacrylate (PMMA) or cycloolefin copolymer (COC), is a promising way to manufacture microfluidic channels and networks [1]. Hot embossing potentially offers lower per-area cost than the micromachining of quartz or silicon and easier scaling-up of production than soft lithography using polydimethylsiloxane [2]. In hot embossing, a...

A self a ne tile in R is a set T of positive Lebesgue measure satisfying A T d D T d where A is an expanding n n real matrix with j det A j m an integer and D fd dmg R n a set of m digits Self a ne tiles arise in many contexts including radix expansions fractal geometry and the construction of compactly sup ported orthonormal wavelet bases of L R They are also studied as interesting tiles In th...

Abstract This statement presents a novel expressive medium that the authors call Ambiguus tiles, which construct dual-view tile mosaics. While similar to wall and surface mosaics made with conventional tiles can be assembled rearranged create in any size form. Fact vs. Fiction, letter sculpture composed of 115 is presented here as an example creative possibilities for using ready-to-use design ...

In a video database system, the answer to a query Q may involve retrieval of a set of segments of one or more videos. When multiple queries are posed by several users, we might wish to reorder the video segments so as to take advantage of the fact that certain video blocks appear in the answers to diierent queries. We assume that the user generating a query is not particularly interested in the...

About 300 years ago Sébastien Truchet systematically studied patterns that could be formed from square tiles that were divided by a diagonal into a white triangle and a black triangle. Other pattern creators have been inspired by him to make Truchet-like tilings composed of circular arcs and other motifs. These tilings are all based on Euclidean tessellations, usually the tiling by squares. In ...

A promising way to gain more insights into how people read and understand a map is by analyzing their eye gaze while working with a map. However, eye gaze logging on interactive maps is challenging due to of various reasons. One of the biggest challenges comes from the interaction with a map that can drastically change the visual representation of the depicted content, making it difficult to de...

The physical properties of plaster bandages are a very important factor in achieving the basic functions of immobilization (maintaining bone fragments in the best possible position), which directly affects the speed and quality of fracture healing. This paper compares the differences between the physical properties of plaster bandages (mass, specific weight, drying rate, elasticity and strength...

An integral self-affine tile is the solution of a set equation AT = ⋃d∈D(T +d), where A is an n× n integer matrix and D is a finite subset of Z. In the recent decades, these objects and the induced tilings have been studied systematically. We extend this theory to matrices A ∈ Qn×n. We define rational self-affine tiles as compact subsets of the open subring R ×∏pKp of the adèle ring AK , where ...

The embossing of thermoplastic polymeric plates is valuable for manufacturing microand nanofluidic devices and diffractive optics. Meanwhile, the imprinting of sub-micrometer-thickness thermoplastic layers has emerged as a lithographic technique with exceptional resolution. Yet neither hot micro-embossing nor thermal nanoimprint lithography will be fully adopted without efficient numerical tech...

introduction: laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. in differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...
