A Sensor Ontology Literature Review

April 18, 2013
Author(s)
Roger D. Eastman, Craig I. Schlenoff, Stephen B. Balakirsky, Tsai H. Hong
The purpose of this paper is to review existing sensor and sensor network ontologies to understand whether they can be reused as a basis for a manufacturing sensor ontology, or if the existing ontologies hold lessons for the development of a new ontology

On the need for an international effort to capture, share and use crystallisation screening data (failure and success)

June 1, 2012
Author(s)
David Gallagher, Janet Newman, Evan E. Bolton, Jochen M?Dieckmann, Vincent J. Fazio, David Lovell, Joseph R. Luft, Thomas S. Peat, David Ratcliffe, Roger A. Sayle, Edward H. Snell, Kerry Taylor, Pascal Vallotton, Sameer Velankar, Frank V. Delft
Crystallisation of biological macromolecules is seen by most structural biologists as a necessary evil, a means to the end, which is knowledge about a macromolecular structure. Crystallization remains largely a trial-and-error process, with extensive

Thermodynamic properties of adamantane revisited

August 2, 2011
Author(s)
Vladimir Diky, Ala B. Bazyleva, Andrey V. Blokhin, Gennady J. Kabo, Mikhail B. Charapennikau, Vladimir N. Emel'yanenko, Sergey P. Verevkin
The heat capacity and parameters of the solid-to-solid phase transition of adamantane were measured in the temperature range (80 to 370) K using adiabatic calorimetry. The thermodynamic functions for the compound in the crystalline and liquid states were
