Minimum Entropy Generation In The Cardiovascular System, Niccole Stephanie Schaible Jan 2011

Minimum Entropy Generation In The Cardiovascular System, Niccole Stephanie Schaible

Electrical and Computer Engineering

This study was performed under the motivation to find a scheme that could describe the complex behavior of cardiovascular homeostasis. This is hypothesized to be manifested in a thermodynamic description of the cardiovascular system (CVS). Seen from a thermodynamic framework, the mechanics of blood flow can be gauged in similar terms as metabolic exchange at the capillaries - thereby providing a holistic and novel perspective on overall CVS function. Entropy generation, a thermodynamic calculation, represents lost work and is hypothesized to reveal something about the "optimal" state of the CVS.

Body Shape Divergence Among Wild And Experimental Populations Of White Sands Pupfish (Cyprinodon Tularosa), Brandon Michael Kowalski

Environmental and Conservation Sciences

Reports of contemporary evolution have become ubiquitous, but replicated studies of phenotypic divergence for wild populations are exceptionally rare. In 2001, a series of experimental populations were established to replicate a historic translocation event that led to a case of contemporary body shape evolution in the White Sands pupfish. Using landmark-based geometric morphometric techniques I examined phenotypic variation for seven of these populations, and two wild populations over a 5 year period (5-10 generations) in the field. Significant body shape divergence was observed, but divergence patterns were not parallel, suggesting that the ponds were ecologically dissimilar. Considerable body shape variation …

Pomdp Planning In Service Composition, Chen Min Jan 2011

Pomdp Planning In Service Composition, Chen Min

Computer Science

Automated vVeb service composition is becoming an increasingly important research topic. It describes the automatic process of composing atomic services into a chain of services that provide a specific functionality that could not be achieved by atomic services alone. A service-oriented environment is dynamic in nature, meaning that services come online and go offiine, services change their functionality, etc. Current classical AI planning techniques suffer from the assumption of deterministic behavior of \Veb services and require execution monitoring for service failures. To address this concern, Partially Observable Markov Decision Processes (POMDP) in workflow composition has been used. POMDPs provide a …
