Advanced nickel-hydrogen cell configuration study
Three nickel hydrogen battery designs, individual pressure vessel (IPV), common pressure vessel (CPV), and a bipolar battery module were studied. Weight, system complexity and cost were compared for a satellite operating in a 6 hour, 5600 nautical mile orbit. The required energy storage is 52 kWh. A 25% improvement in specific energy is observed by employing a bipolar battery versus a battery comprised of hundreds of IPV's. Further weight benefits are realized by the development of light weight technologies in the bipolar design
Differential Renormalization of Gauge Theories
The scope of constrained differential renormalization is to provide
renormalized expressions for Feynman graphs, preserving at the same time the
Ward identities of the theory. It has been shown recently that this can be done
consistently at least to one loop for abelian and non-abelian gauge theories.
We briefly review these results, evaluate as an example the gluon selfenergy in
both coordinate and momentum space, and comment on anomalies.Comment: LaTex, 8 pages with 1 ps figures, talk given at the Zeuthen Workshop

Majorana neutrino oscillations in vacuum
In the context of a type I seesaw scenario which leads to get light
left-handed and heavy right-handed Majorana neutrinos, we obtain expressions
for the transition probability densities between two flavor neutrinos in the
cases of left-handed and right-handed neutrinos. We obtain these expressions in
the context of an approach developed in the canonical formalism of Quantum
Field Theory for neutrinos which are considered as superpositions of
mass-eigenstate plane waves with specific momenta. The expressions obtained for
the left-handed neutrino case after the ultra-relativistic limit is taking lead
to the standard probability densities which describe light neutrino
oscillations. For the right-handed neutrino case, the expressions describing
heavy neutrino oscillations in the non-relativistic limit are different respect
to the ones of the standard neutrino oscillations. However, the right-handed
neutrino oscillations are phenomenologically restricted as is shown when the
propagation of heavy neutrinos is considered as superpositions of
mass-eigenstate wave packets.Comment: 25 pages, abstract changed, two sections added, some references adde
