Unit consists of state-of-charge indicator panel, control panel, monitor panel, power panel, charging-current power supply, and load panel

Nonleptonic Weak Decays of B to D_s and D mesons

Branching ratios and polarization amplitudes for B decaying to all allowed pseudoscalar, vector, axial-vector, scalar and tensor combinations of D_s and D mesons are calculated in the Isgur Scora Grinstein Wise (ISGW) quark model after assuming factorization. We find good agreement with other models in the literature and the limited experimental data and make predictions for as yet unseen decay modes. Lattice QCD results in this area are very limited. We make phenomenological observations on decays in to D_s(2317) and D_s(2460) and propose tests for determining the status and mixings of the axial mesons. We use the same approach to calculate branching ratios and polarization fraction for decays in to two D type mesons.Comment: 21 pages, 9 figures. v3: updated to reflect changes in published paper, conclusions unchanged (see source file for details). Added comments on factorization. v2: experimental data updated, references added, tables of results added, more on axial D_s mixing, added section on D D decay modes and typos correcte

An Economic Analysis of Fluid Milk Processing in Alaska

Alaskan fluid milk is processed for market by a two-firm industry. In Delta Junction, the Northern Lights Dairy obtains milk from two producers and services an Interior market from Delta to Fairbanks. In Anchorage , Matanuska Maid (M-M) obtains milk from II producers and markets its products largely in southcentral Alaska and , to a less extent, in Fairbanks. Direct competition between the two is minimal. The principal source of competition is preprocessed fluid milk shipped in from Puget Sound

Exclusive pi^+ production at HERMES

Hard exclusive production in deep inelastic lepton scattering provides access to the unknown Generalized Parton Distributions (GPDs) of the nucleon. At HERMES, different observables for hard exclusive pi^+ production have been measured with a 27.6 GeV positron beam on an internal hydrogen gas target. First preliminary results for the unpolarized ep->enpi^+ total cross section for 1.5<Q^2<10.5 GeV^2 and for 0.02<x<0.8 are presented and compared to GPD calculations. The final result for the single-spin asymmetry using a longitudinal polarized target is also reported.Comment: 5 pages, 3 figures, contribution to the XII International Workshop on Deep Inelastic Scattering, April 14-18, 2004, Strbske Pleso, Slovaki

Prediction of gas leakage of environmental control systems

Mathematical models of leakage configurations and various flow theories are presented with the substantive experimental test data to provide background material for future design and failure analysis. Normal-rate leakage and emergency, high-rate leakage are considered
