... The plug-plates of SDSS project are responsible for locating the optical-fiber plugs spatially and for defining the plug tilt with respect to the surface of best focus. ... Previous attempts to match the SDSS plug-plates to the surface of best focus were conducted using only the bending fixture. The analyses performed indicated that by adding a central constraint to the plug-plate deformation process, the plates could be made to match the surface of best focus within an acceptable range of error. ...

In this method the fields outside and inside a particle are represented by expansions in term of proper basis functions (practically always the vector spherical harmonics). Since the particle surface does not coincide with the coordinate surface, it is impossible to satisfy the boundary conditions exactly, and the expansions are limited by a finite number of terms, and the boundary conditions are considered in a finite set of points (matching points). ...

... The SINIS mixer combines the advantages of a hot-electron bolometer (HEB), such as a high signal frequency at a small local oscillator power, with the advantages of an SIS mixer, including low noise level, a high intermediate frequency, and wide working temperature range (up to a critical temperature of the superconductor). ... The SIS mixer allows a noise temperature lower than 100 K (which is equivaq lent to several quantum noise limits T n = hf/k) to be reached at frequencies below 1 THz [1]. ...
