Recently, invisible cloaks have attracted much attention due to their exciting property of invisibility, which are based on a solid theory of transformation optics and quasi-conformal mapping. Two kinds of cloaks have been proposed: free-space cloaks, which can render objects in free space invisible to incident radiation, and carpet cloaks (or ground-plane cloaks), which can hide objects under ...

The Notes that follow are meant to supplement, and not to replace, the translation of the book Shaft Weaving and Graph Design by Olivier Masson and Francois Roussel, hereinafter referred to as M&R. All quotes and references are to the translation. The Notes' organization is as follows: a summary of M&R's entire book is provided, summarizing and identifying book sections of interest to weavers a...

ABSTMCT: Reduction in the requirements for water, energy, and chemicals have been achieved by changes in carpet beck dyeing procedures. Instead of discharging the dyebath following each dye cycle, in the new procedure the spent bath is analyzed, reconstituted to the desired concentration of dyes and auxiliary chemicals, and reused. Bench scale dyeings were conducted initially to define operat...

The flux of emerging aquatic insects from streams can provide a significant energy subsidy to riparian web-building spiders. However, despite the high temporality of aquatic insect emergence, the effects of such aquatic insect dynamics on spider distribution are poorly understood. To examine the relationship, the aquatic insect flux from a headwater stream in a northern Japanese deciduous fores...

The rates of oxygen consumption and carbon dioxide release of primitive hunters and weaver spiders, the Chilean Recluse spider Loxosceles laeta Nicolet (Araneae: Sicariidae) and the Chilean Tiger spider Scytodes globula Nicolet (Araneae: Scytodidae), are analyzed, and their relationship with body mass is studied. The results are compared with the metabolic data available for other spiders. A lo...

Cellular automata are used for designing highperformance applications in many areas. This paper describes CARPET, a high-level programming language based on the cellular automata model. CARPET is a programming language designed to support the development of parallel high performance software. It exploits the computing power of a highly parallel computer releasing a user from using explicit para...
