High operating temperature electronic components are needed for a variety of military, aerospace, down-hole, and electric vehicle applications. One of the limiting technologies is the availability of highly reliable capacitors that operate at temperatures greater than 150°C and up through 250°C.
This paper introduces a high breakdown strength dielectric film Gore has developed for metallized film capacitors. In addition to exceptionally high breakdown voltages, the 6 μm PTFE film exhibits low dissipation factor and stable capacitance over a wide temperature range. Film properties were tested from −50°C to 250°C and both wound film/foil and metallized film capacitors were fabricated and tested from RT to 300°C.
This paper presents a three-integers multiplication algorithm R = A * X * Y for Reconfigurable Mesh (RM). It is based on a three-integer multiplication algorithm for faster FPGA implementations. We show that multiplying three integers of n bits can be performed on a 3D RM of size (3n + log n + 1) × (2n+1 +3) × n+1 using 44 + 18 · log log MNO steps, where MNO is a bound which is related to the number of sequences of ‘1’s in the multiplied numbers. The value of MNO is bounded by n but experimentally we show that on the average it is n. Two algorithms for solving multiplication on a RM exists and their techniques are asymptotically better time wise, O(1) and O(log* n), but they suffer from large hidden constants and slow data insertion time (O(n)) respectively. The proposed algorithm is relatively simple and faster on the average (via sampling input values) then the previous two algorithms thus contributes in making the RM a practical and feasible model. Our experiments show a significant improvement in the expected number of elementary operations for the proposed algorithm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
