Brewing has a long history in this country—first making an appearance in 1620 with the landing of the Pilgrims at Plymouth Rock in Massachusetts. Today, beers can be easily categorized into one of two types: 1) industrial, and 2) craft. The focus of this paper is on this second type, the "craft beer" and the so-called "renaissance" it experienced during the 1980s. In 1983, there were only 43 op...
The shocks and impacts encountered on small high-speed craft exceed the limits set for safe working practice according to current standards. European legislation regarding the exposure to vibration will have far reaching effects on the operators of such craft with respect to the safety of their employees. This paper sets out to highlight the vibration dose values that can be expected during typ...
ACADIA 2007 The distinction between matter (mechanics) and information (electronics) in the context of responsive building skins has promoted unique design protocols for integrating sensor technologies into material components. Such a distinction results in applications of remote sensing after the process of material fabrication. Sensors are commonly perceived as electronic patches which initia...
Traditionally, programming languages have been designed with an eye toward implementation on general-purpose computers. The advent of computationally-enhanced craft items–small programmable objects with simple geometries and scaled-down computational components–suggests the need for new language and software environment models tailored for these objects. In some respects, the task of the craft-...
A comprehensive and critical review of literature pertaining to the study of planing craft is given within this work. This study includes monohull design, analysis and performance prediction for flat water; many features of the planing characteristics, including dynamic stability, the use of stepped hullforms, re-entrant transoms and flow characteristics are detailed. Work on the rough water se...
BACKGROUND Exceptional aging, defined as reaching age 85 years, shows geographic inequalities that may depend on local environmental conditions. Links between particulate pollution-a well-recognized environmental risk factor-and exceptional aging have not been investigated. OBJECTIVES We conducted a nationwide analysis of ~28 million adults in 3,034 United States counties to determine whether...
