Unmanned aerial vehicles (UAVs) have been carefully optimized for forward flight regimes over the past fifty years. While engineers learned to construct highly maneuverable craft to be flown by human operators, autonomous control of such highly underactuated systems has continued to be a difficult issue. New flight capabilities for aircraft have been enabled through recent advances in materials...

We present a framework for clustering with cluster-specific feature selection. The framework, CRAFT, is derived from asymptotic log posterior formulations of nonparametric MAP-based clustering models. CRAFT handles assorted data, i.e., both numeric and categorical data, and the underlying objective functions are intuitively appealing. The resulting algorithm is simple to implement and scales ni...

Having a work-related identity is central to being an adult in America. Going to work and engaging in prescribed work behaviors in the workplace is the usual or typical way that adults achieve worker identities. The purpose of this study, developed from an ethnography of people who make crafts at home and sell their work at craft fairs, was to examine how worker identity is constructed when ind...

Digital fabrication, and especially 3D printing, is an emerging field that is opening up new possibilities for craft, art and design. The process, however, has important limitations; in particular, digitally designed artifacts are intrinsically reproducible. In stark contrast, traditional craft artifacts are individually produced by hand. The authors combine digital fabrication and craft in the...

This paper presents interim research findings of a project which seeks to elicit the skilled knowledge of master craftsmen through use of an expert learner (Horne) acting as intermediary between the craftsmen and a designer (Wood) creating a multimedia resource to support those wishing to learn the skill. It builds on previous research that evolved a set of principles for the design of multimed...

Hydrofoils are a current hot topic in the marine industry both high performance sailing and new passenger transport systems conjunction with electric propulsion. In community, largest impact is seen from America’s cup, where boats sailed at more than 50 knots (over 100 km/h) 100% “flying” time. also becoming popular Olympics, as 2024 Olympic games 5 gold medals will be decided on foiling boats/...
