Sea cucumber catch has followed “boom-and-bust” patterns over the period of 60 years from 1950-2010, and sea cucumber fisheries have had important ecological, economic and societal roles. However, sea cucumber fisheries have not been explored systematically, especially in terms of catch change trends. Sea cucumbers are relatively sedentary species. An attempt was made to explore whe...

to appear in Astrophys. J. document On Non-Primordial Deuterium Production by Accelerated Particles Tijana Prodanović and Brian D. Fields Center for Theoretical Astrophysics, Department of Astronomy, University of Illinois abstract Deuterium plays a crucial role in cosmology because the primordial D/H abundance, in the context of big bang nucleosynthesis (BBN) theory, yields a precise measure o...

While the devices for media capture have advanced from mechanical to computational since the invention of photography and motion pictures in the 19 century, their underlying user interaction paradigms have remained largely unchanged. Current interaction techniques for media capture do not leverage computation to solve key problems: the skill required to capture high quality media assets; the ef...

Abstract The production preparation process (3P) enables collaboration between design and engineers during product development but its efficiency is limited by the abundance of documentation manufacturing constraints capabilities. Empirical studies showed that use requirements can increase 3P, however, support for to capture share scarce. A method in identifying, defining, structuring sharing c...

Archaeological evidence indicates that fishing was one of the earliest human production activities. Early fishing seems to have been mainly hunting and gathering along shores and inlets with fish farming emerging somewhat later in time. Capture fisheries expanded rapidly in the 19 and 20 centuries AD reaching the peak annual production of over 90 million metric tonnes in the early 1990s. Since ...

Production of highly viscous tar sand bitumen using Steam Assisted Gravity Drainage (SAGD) with a pair of horizontal wells has advantages over conventional steam flooding. This paper explores the use of Artificial Neural Networks (ANNs) as an alternative to the traditional SAGD simulation approach. Feed forward, multi-layered neural network meta-models are trained through the Back-...
