Data Type support. Functional qualities, such as `map' and `apply'. Is Such a System Possible? Work carried out has already proven that many of the key ideas to the proposed system are realistic [Bai91], [Bai94] and [Bai95]. Compelling arguments can be given, using only existing computer science knowledge and techniques, that the remaining concepts are attenable. Dynamic primitives are fully re...
Short-period superconducting undulators are being developed at the Advanced Photon Source (APS). A 21period undulator prototype is being fabricated. Later, the short coil will be replaced with a longer one using the same cryostat. A high quality magnetic field with a phase error of 2 degrees rms was achieved in the prototype magnets due to accurate winding of the superconducting coils on the pr...
Abstract Additionally to the achievable tight geometrical tolerances, rotary swaging can influence intrinsic material properties by work hardening and residual stresses generation. Although should be usually avoided, they used on purpose improve performance of a produced part. To find prospective process settings, 2D FEM simulation was developed revealed development distributions in E355 steel ...
Salinity is rising in many southern African and Australian rivers with unknown effects on aquatic organisms. The extent of spatial variation, at any scale, in salt tolerances is unknown and therefore whether data from one location should be used elsewhere. The acute tolerances (72-hour LC50) to sea salt of 49 macroinvertebrate taxa from the south-east of the Eastern Cape (SEEC), South Africa we...
We present in this paper a new analysis of relative sensitivity/importance of calibra-tion/alignment parameters on the performance of stereoscopic depth reconstruction. This quantitative analysis provides formulae which relate diierent parameter errors to the 3D reconstruction measurements. The results of this analysis provide specii-cations of acceptable tolerances in individual calibration pa...
(a) Acceptable daily intake (ADI). The ADI for total residues of virginiamycin is 250 micrograms per kilogram of body weight per day. (b) Tolerances—(1) Swine. Tolerances are established for residues of virginiamycin in uncooked edible tissues of 0.4 part per million (ppm) in kidney, skin, and fat, 0.3 ppm in liver, and 0.1 ppm in muscle. (2) Broiler chickens and cattle. A tolerance for residue...
─ The impact of tag antenna and chip impedance tolerances on power transfer between these components is investigated analytically. Means for efficient computation of the minimum and maximum power transmission coefficient under given impedance tolerances are developed. The presented sensitivity analysis is employed to quantify the design uncertainty of single and double T-matched short dipole ta...
As a simple and highly accurate axial force management method during manufacturing maintenance of bolt-tightened structures, we examined to calculate the from images bolt head. In this method, is calculated using strain on head measured by digital image correlation (DIC) technique relationship between finite element analysis (FEA). We through two comparisons. The first was compare DIC with gaug...
