Sailing Past the Horizon

The KJH: Sailing over the horizon

On March 31, 2010, the first English issue of the Korean Journal of Hematology (KJH) was published and dispatched to overseas libraries and domestic readers. It was the emotional zenith of my editorial career. At last, the KJH has been reborn as an international journal to fulfill our mission of delivering new and important scientific knowledge and information regarding all aspects of hematolog...

Sailing past the horizon. The histologic diagnosis of celiac disease in "nonflat" intestinal mucosa.

When one reads about the histologic features of celiac disease in a textbook of surgical pathology, it is the absence of normal intestinal villi that generally is stressed as the key diagnostic feature. The features of a “flat mucosa,” in combination with elongation of the intestinal crypts, evidence of epithelial damage, and a variable increase in chronic inflammation of the lamina propria, fo...

Microgravity Manufacturing: Extending Rapid Prototyping Past the Horizon

Over the last decade, rapid prototyping (RP) technologies have continued to advance in all aspects of operation and application. From continuously advanced materials and processes development to more hard-core manufacturing uses, the RP realm has stretched considerably past its original expectations as a prototyping capability. This paper discusses the unique applications for which NASA has cho...

Reinforcement Sailing

This thesis examines applying reinforcement learning to sailing. We give two conceptually different models of a simple sailing boat. Standard tabular reinforcement learning is shown to be ineffective in controlling these naturally continuous models. We examine a method [Smith, 2001b] which adaptively quantises both the state and action spaces and show that it has similar performance to the tabu...
