Design aspects of multiple-order diffraction engineered surface (MODE) lenses are discussed that result in significant improvement of geometrical off-axis performance. A new type of aberration that is characteristic of this type of segmented lens, which is called zonal field shift, is minimized by curving front intercepts of zone transitions. Three MODE designs are compared, based on a 240 mm ...
2017-8-1 · Design aspects of a large scale turbomolecular pump with active magnetic Vacuum ( IF 3.627) Pub Date : 2017-08-01, DOI: 10.1016/j.vacuum.2016.12.010 Bangcheng Han, Ziyuan Huang, Yun Le Abstract A large scale 5-axis magnetically levitated turbomolecular pump
The paper considers design and manufacturing problems of a toroidal shell/liner system with major/minor liner radii of 180/60 cm for a high-beta reversed field pinch device with a maximum plasma current of 2 MA. Stress-analysis figures for the shell show that because of the vacuum load the net forces on the bolting system do not impose undue restraints. The key problems concerning the shell ...
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We study the large N reduced model of D-dimensional Yang-Mills theory with special attention to dynamical aspects related to the eigenvalues of the N ×N matrices, which correspond to the space-time coordinates in the IIB matrix model. We first put an upper bound on the extent of space time by perturbative arguments.
2017-8-23 · Seismic Hazard and Seismic Design and Safety Aspects of Large Dam Projects Martin Wieland Abstract Earthquakes can affect large dam projects in many different ways. Usually, design engineers are focussing on ground shaking and neglect the other aspects. The May 12, 2008 Wenchuan earthquake has damaged 1803 dams and reservoirs.
The potential benefits of functional magnetic resonance imaging (MRI) for the investigation of normal development have been limited by difficulties in its use with children.
