Mobilizing for the \u2790s

[Excerpt] CWA\u27s general strategy for the \u2790s can be summarized as increasing the involvement of our members at work, in their communities, and in building our Union. Building on our tradition of industrial unionism, we continue to organize and negotiate for higher pay, benefits and job security. Additionally, as we move into the 21st Century, we need to expand our vision to include worker involvement in building meaningful worklives and careers. This broader outlook helps increase the participation of our members in mobilizing around contract goals, organizing new members, and supporting other workers in their efforts to achieve Jobs with Justice. The greater the level of participation among the membership, the more active and stronger the union

Status of the NASA/General Electric experimental clean combustor program, phase 3

The technology required to design and develop advanced commercial, conventional-takeoff-and-landing aircraft engines with significantly lower pollutant exhaust emissions levels than those of current-technology engines was generated and demonstrated. The target pollutant emissions reductions in tests of an advanced commercial aircraft turbofan engine were attained by developing advanced combustor designs. This technology is intended to be applicable to advanced military aircraft engines. The primary focus was on reducing the levels of the gaseous pollutant emissions

Gauge-invariant coherent states for Loop Quantum Gravity II: Non-abelian gauge groups

This is the second paper concerning gauge-invariant coherent states for Loop Quantum Gravity. Here, we deal with the gauge group SU(2), this being a significant complication compared to the abelian U(1) case encountered in the previous article. We study gauge-invariant coherent states on certain special graphs by analytical and numerical methods. We find that their overlap is Gauss-peaked in gauge-invariant quantities, as long as states are not labeled by degenerate gauge orbits, i.e. points where the gauge-invariant configuration space has singularities. In these cases the overlaps are still concentrated around these points, but the peak profile exhibits a plateau structure. This shows how the semiclassical properties of the states are influenced by the geometry of the gauge-invariant phase space.Comment: 60 pages, 8 figure

Gauge-invariant coherent states for Loop Quantum Gravity I: Abelian gauge groups

In this paper we investigate the properties of gauge-invariant coherent states for Loop Quantum Gravity, for the gauge group U(1). This is done by projecting the corresponding complexifier coherent states, which have been applied in numerous occasions to investigate the semiclassical limit of the kinematical sector, to the gauge-invariant Hilbert space. This being the first step to construct physical coherent states, we arrive at a set of gauge-invariant states that approximate well the gauge-invariant degrees of freedom of abelian LQG. Furthermore, these states turn out to encode explicit information about the graph topology, and show the same pleasant peakedness properties known from the gauge-variant complexifier coherent states.Comment: 36 page
