light on the evolution of four-limbed animals from fish in the a lmost four billion years since life on earth oozed into existence, evolution has generated some marvelous metamorphoses. One of the most spectacular is surely that which produced terrestrial creatures bearing limbs, fingers and toes from water-bound fish with fins. Today this group, the tetrapods, encompasses everything from birds...

Getting Back Up to Speed: Cognitive Principles for Situation Awareness Recovery

Objective: To provide a principled, theoretical basis to improve interface tools for helping users recover from task interruptions and get back up to speed in dynamic operational tasks. Background: Multi-tasking and interruptions that disrupt situation awareness are common to many dynamic operational tasks, from monitoring airspaces and plant operations to conducting tactical missions, civil em...

On Computational Speed-Up

Let J? be any effective mapping from total functions on the integers to total functions. Composition and iterated composition are examples of such mappings. The "operator speed-up theorem in this paper establishes the existence of a computable function f such that for any program computing f(x) in Pj(x) steps for all x, there is another program computing f(x) in p 0(x) steps and F(p 0) < palmos...

There is growing interest in the food production industry for technologies to prevent waste discharges. Due to ever increasing industrial wastewater discharge regulations, food manufacturers are keen on pursuing economical and progressive alternatives to publicly owned treatment works (POTW) treatment. A microbial fuel cell (MFC) is a type of bioreactor that utilizes the electrochemical potenti...
