The need for a better understanding of the physicochemical properties of radiation-sensitive thin polymer coatings for lithographic applications is driven by
This paper first overviews photometric quantities of lamps - luminous flux, luminous intensity, illuminance, and luminance - and general techniques for
The vacuum systems of all scanning electron microscopes (SEMs), even in the so-called clean instruments, have certain hydrocarbon residues that the vacuum pumps

The research and design of an active millimeter-wave concealed object imaging system is described. Several illumination and detection methods were analyzed via
Erich N. Grossman, Shalva Nolen, Nicholas Paulter, Carl D. Reintsema
We describe a system for detection of concealed weapons based upon imaging the millimeter-wave reflectance contrast between the weapon and the human body. An
A description will be given of the ongoing Comite International des Poids et Measures (CIPM) key comparison programs in force. The participation of the National
Force calibrations obtainable at the National Institute of Standards and Technology (NIST) continue to focus on extracting the maximum performance from the

The history of testing heat insulators at the National Institute of Standards and Technology (formerly the National Bureau of Standards is nearly as long as the
We study the ferroelectric phase transition in PbSc1/2Nb1/2O3 (PSN) using a first-principles effective Hamiltonian approach. Results for PSN with NaCl-type
We describe the status of a genetic programming system that is based on a procedural program representation. The procedural representation is closely related to
This paper presents the design and implementation of a simulation model for the cdma2000 reverse link. The model includes all the radio configurations and their
We present simulation results of the effect of nanoscopic and micron-sized fillers on the structure, dynamics, and mechanical properties of polymer melts and
The difficulty in manufacturing Rockwell diamond indenters to the required geometric specifications has resulted in most commercially manufactured indenters to
Differential thermal analysis and thermogravimetric analysis (DTA/TGA) experiments have been completed in the BaF2-BaO-Y2O3-CuOx-H2O system at various oxygen
