A simplified theoretical model based on geometrical optics (GO) in combination with physical optics (PO) in its vector form is used to analyze the performance of a homogeneous dielectric-sphere lens fed by a feed horn. The proposed model provides physical insight and sufficient accuracy for the initial design cycle. The computed results are also compared to measured data acquired from a prototy...

Itai and Rodeh [IR] have proved thal for any 2-conncctcd graph G and any vertex S E G there are two spanning trees such that the paths from any othcr vcrtex to s on the trees are disjoint. In this p,aper the result is generalized to 3-connected graphs. T ec hn io n C om pu te r Sc ie nc e D ep ar tm en t T eh ni ca l R ep or t C S0 46 2 19 87 -1

We make two contributions in this article. First, we examine whether social comparisons have behavioral effects on workers’ performance when a firm can choose workers’ wages or let them choose their own. Firms can delegate the wage decision to neither, one or both workers in the firm. We vary the information workers receive, finding that social comparisons concerning both wages and decision rig...

In this study, the photospheric vector magnetograms obtained by Helioseismic and Magnetic Imager on-board the Solar Dynamics Observatory are used as boundary conditions for a CESE-MHD model to investigate some photosphere characteristics around the time of a confined flare in solar active region NOAA AR 11117. We report our attempt of characterizing a more realistic solar atmosphere by includin...

A brief review of the theory contributions presented in the EC-18 Workshop is given. The covered spectrum of topics is quite broad including the electron cyclotron wave propagation physics as well the results of numerical modelling of transport and current drive.

I survey the parameter space of NAHE-based free fermionic heterotic string models. First, I discuss flat directions of the low energy effective field theories and show that D-flat directions need not be isomorphic to gauge invariant superpotential terms. Next, I review recent studies of three generation SU(3)C × SU(2)L × U(1)Y , SU(3)C ×SU(2)L ×SU(2)R ×U(1)B−L, SU(4)C × SU(2)L ×U(1)Y ′ , and fl...
