Satellite data relay and platform locating in oceanography. Report of the In Situ Ocean Science Working Group
The present and future use of satellites to locate offshore platforms and relay data from in situ sensors to shore was examined. A system of the ARGOS type will satisfy the increasing demand for oceanographic information through data relay and platform location. The improved ship navigation provided by the Global Positioning System (GPS) will allow direct observation of currents from underway ships. Ocean systems are described and demand estimates on satellite systems are determined. The capabilities of the ARGOS system is assessed, including anticipated demand in the next decade

Quantification of temporal fault trees based on fuzzy set theory
© Springer International Publishing Switzerland 2014. Fault tree analysis (FTA) has been modified in different ways to make it capable of performing quantitative and qualitative safety analysis with temporal gates, thereby overcoming its limitation in capturing sequential failure behaviour. However, for many systems, it is often very difficult to have exact failure rates of components due to increased complexity of systems, scarcity of necessary statistical data etc. To overcome this problem, this paper presents a methodology based on fuzzy set theory to quantify temporal fault trees. This makes the imprecision in available failure data more explicit and helps to obtain a range of most probable values for the top event probability
Anomalous Mediated SUSY Breaking, Fermion Masses and Natural Suppression of FCNC and CP Violating Effects
We construct realistic supergravity models where supersymmetry breaking
arises from the -terms of an anomalous gauge symmetry broken at the
Planck scale. The model has the attractive feature that the gaugino masses, the
and terms and the mass splittings between the like-charged squarks of
the first two generations compared to their average masses are all suppressed.
As a result, the electric dipole moment of the neutron as well as the flavor
changing neutral current effects are predicted to be naturally small. These
models predict naturally the expected value of the -term and also have the
potential to qualitatively explain the observed mass hierarchy among quarks and
leptons.Comment: Some references adde
Modified Wet Distillers Grains Finishing Diets May Increase the Levels of Polyunsaturated and Trans Fatty Acids of Beef
Yearling steers (n=268) were fed 0%, 10%, 20%, 30%, 40% or 50 % modified wet distillers grains with solubles (MWDGS; DM basis). Marbling attributes, intramuscular fat content and fatty acid profile of beef were analyzed. Treatments did not alter marbling score, marbling distribution or fat content. Slight differences were identified for marbling texture of Choice carcasses. Values of polyunsaturated, Omega 6 and trans fatty acids linearly increased as levels of modified wet distillers grains increased. Feeding this byproduct increases polyunsaturated, trans and Omega 6 fatty acids in beef
Technicolor Theories with Negative S
We show that the pseudo Nambu--Goldstone boson contribution to the
Peskin--Takeuchi electroweak parameter can be negative in a class of
technicolor theories. This negative contribution can be large enough to cancel
the positive techni-hadron contribution, showing that electroweak precision
tests alone cannot be used to rule out technicolor as the mechanism of
electroweak symmetry breaking.Comment: (LBL-32893, UCB-PTH 92/34, 10 pages; we added a discussion of
uncertainties, fine-tuning, and SU(2) asymptotic freedom; the conclusions are
unchanged.
