A special class of braids, called woven, is introduced and it is shown qcxthat every conjugation class of the braid group contains woven braids. In consequence tame links can be presented as plats and closures of woven braids. Restricting on knots we get the ‘woven version’ of the well-known theorem of Markov, giving moves that are capable of producing all woven braids with equivalent closures....

Constructions of woven graph codes based on constituent convolutional codes are studied, and examples of woven convolutional graph codes are presented. Existence of codes satisfying the Costello lower bound on the free distance within a random ensemble of woven graph codes based on s-partite, s-uniform hypergraphs is shown, where s depends only on the code rate. Simulation results for Viterbi d...

Flexural strength and modulus of woven glass fiber-reinforced specimens werc significanLly greater than those without woven glass fiber (p<O.OD, Likewise, comprossive strength of reinforced specimens was signifieantly greater than those without woven glass fiber (p<O.Ol), except for specimens rcjnforced with woven glass fiber oriented at a tilt directio...

The aim of this investigation was to measure the flexural and compressive strengths and the corresponding moduli of cylindrical composite specimens reinforced with woven glass fiber. Test specimens were made by light-curing urethane dimethacrylate oligomer with woven glass fiber of 0.18-mm standard thickness. Tests were conducted using four reinforcement methods and two specimen diameters. Flex...

Spontaneous coronary artery dissection (SCAD) and woven coronary artery anomaly (WCAA) are relatively rare. A few of the previously reported woven coronary artery cases have involved in a single coronary artery. We present an unusual woven case involving all coronary arteries and two patient with SCAD. We have also reviewed the literature related to these disease, as they resemble one another.

Tensile strength, Young's modulus, and toughness of electrospun nylon 6 non-woven fiber mats were improved by increasing individual nanofiber strength and fiber-fiber load sharing. Single-walled carbon nanotubes (CNTs) were used as reinforcement to increase the strength of the electrospun nylon 6 nanofibers. Young's modulus, tensile strength, and toughness of the nylon 6 non-woven fiber mats el...

In the spring of 2005 our department offered a new course entitled “Intelligent Systems” (IS). This course, which will be required for future CS majors, provides an introduction to a number of AI topics including predicate logic, frames, rule-based systems, neural networks, Bayesian networks, decision trees, and fuzzy logic. The theme of agents is woven throughout the course. Each section of th...

BACKGROUND There are different materials and principles used in the construction of bed encasings. Although these covers claim to have antimite properties, they might not be mite proof. OBJECTIVE This study evaluated the effectiveness of mite penetration of these covers by using the Siriraj chamber method. METHODS Thirty-two covers collected from 9 different countries were categorized accor...

partial frames provide a rich context in which to do pointfree structured and unstructured topology. a small collection of axioms of an elementary nature allows one to do much traditional pointfree topology, both on the level of frames or locales, and that of uniform or metric frames. these axioms are sufficiently general to include as examples bounded distributive lattices, $sigma$-frames, $ka...

INTRODUCTION Mouse models are used frequently to study effects of bone diseases and genetic determinates of bone strength. Murine bones have an intracortical band of woven bone that is not present in human bones. This band is not obvious under brightfield imaging and not typically analyzed. Due to the band's morphology and location it has been theorized to be remnant bone from early in life. Fu...
