Seeing as though

Seeing Galaxies though Thick and Thin

The superimposed pair of spiral galaxies comprising NGC 3314 ooers a unique opportunity to trace the dust properties in a spiral galaxy. We analyze multicolor HST imaging, supported by ground-based near-IR imaging and ber-array spectroscopy to measure dust extinction in the foreground Sc galaxy NGC 3314A, which is backlit by the Sb system NGC 3314B. The superposition allows us to measure extinc...

Delta Design: Seeing/Seeing as

“....On ne trouvera point de Figures dans cet Ouvrage. Les methodes que j’y expose ne demandent ni constructions, ni raisonnements geometriques ou mechaniques, mais seulement des operations algebriques, assujetties a une marche reguliere et uniforme. Ceux qui aiment l’Analyse, verront avec plaisir la Mechanique en devenir une nouvelle branche, et me savront gre d’en avoir etendu ainsi le domain...

Seeing is as Good as Doing

Given the privileged status claimed for active learning in a variety of domains (visuomotor learning, causal induction, problem solving, education, skill learning), the present study examines whether action-based learning is a necessary, or a suffi cient, means of acquiring the relevant skills needed to perform a task typically described as requiring active learning. To achieve this, the presen...

Running on four legs as though they were one

that run on one leg. The generalization uf these one-leg algorithms for control of machines with several legs is explored. The generalization is quite simple when multilegged systems run with gaits that use the support legs one at a time. For these gaits the ~ n e-l e g algorithms can be used b o control multilegged running. The cortcept of a virtual leg is introduced to further extend the appr...
