Solder joints, which serve as mechanical and electrical interconnects in a package, are particularly prone to failure during a drop. Hence, the fracture behavior of solders at high strain rates and in mixed mode is a critically important design parameter. This study reports the effects of (a) loading conditions (strain rate and loading angle), (b) reflow parameters (dwell time and cooling rate), and...
Single crystal Silicon has been produced using a cast-in-place process usually used for multicrystalline ingot production. This Mono2 TM material produces higher cell efficiencies compared to multi crystalline silicon material with the same average minority carrier lifetime. Profiles of lifetime through the height of the brick and across the ingot demonstrate rough equivalency in bulk lifetime between...
An approach is presented for high throughput matching of regular expressions (regexes) by first converting them into corresponding non-deterministic finite automata (NFAs) which are then configured onto a FPGA. The key novel feature is a technique that, for any given regex, constructs an NFA that processes multiple characters per clock cycle. An efficient algorithm is proposed that outputs an NFA...
Type-II superlattice formed by In0.53Ga0.47As/GaAs0.51Sb0.49 wafers have been grown on InP substrates. The superlattice is studied in several aspects to explore its potential in achieving ≫2.1μm detection InP-based avalanche photodiodes. The ionisation coefficients of the superlattice In0.53 Ga0.47As(5nm) /GaAs0.47Sb0.49 (5nm) are found to be similar to those of In0.53 Ga0.47 As. Hence the more compatible...
This research aims to develop InP-based devices as alternative for MWIR detection. The approach pursued is a type-II superlattice consisting GaInAs and GaAsSb alloys. These structures provide two advantages for MWIR detection: large (greater than 700 meV) direct band-gaps, which should lead to a lower thermal carrier generation rate and the ability to adjust the detection wavelength by changing the...
This paper presents an efficient method for finding matches to a given regular expression in given text using FPGAs. To match a regular expression of length n, a serial machine requires 0(2^n) memory and takes 0(1) time per text character. The proposed approach reqiures only 0(n^2) space and still process a text character in 0(1) time (one clock cycle).The improvement is due to the Nondetermineistic...
