In this paper, the acceleration effect of nickel (Ni) on direct nitridation process diamond-wire saw powder (DWSP) was investigated. The DWSP doped with Ni additives were nitrided at different temperatures. To study mechanism accelerated nitridation, thermodynamics Si-O-N-Ni and processes analyzed by FactSage 7.2 single-crystal silicon blocks also instead DWSP. results revealed that decreased t...

An algorithm is presented to fit precipitates in atom probe tomographic data sets as equivalent ellipsoids. Unlike previous techniques, which measure only the radius of gyration, these ellipsoids retain the moments of inertia and principle axes of the original precipitate, preserving crystallographic orientational information. The algorithm is applied to study interconnected γ-precipitates (L12...

In this work, we report on the importance of layer distribution after annealing to form a high quality ohmic contact p-type GaN, using nickel (Ni) and gold (Au) thin association. Both standard GaN/Ni/Au its reverse, GaN/Au/Ni GaN were studied. The Au/Ni stack exhibits most promising results in study. While quasi-linear current-voltage (I-V) characteristic, counterpart, GaN/Au/Ni, shows pure beh...

On equivalence and emptiness problems of multi-letter (measure many) quantum finite automata Abstract In this paper, we study some decision problems both for multi-letter quantum finite au-tomata and measure many multi-letter quantum finite automata. We first show that given a k1-letter quantum finite automaton A1 and a k2-letter quantum finite automaton A2 over the same input alphabet Σ, they ...

In this report, we continue studying Logic Synthesis Preserving Specification (LSPS). Given a combinational circuit N and its partition into subcircuits N1,..,Nk (this partition is called a specification of N), LSPS optimizes N by replacing each subcircuit Ni with toggle equivalent subcircuit Ni. As we showed before, LSPS is scalable. In this report, we demonstrate that LSPS can be also viewed ...

Mineral carbonation of basic silicate minerals regulates atmospheric CO(2) on geological time scales by locking up carbon. Mining and spreading onto the earth's surface of fast-weathering silicates, such as olivine, has been proposed to speed up this natural CO(2) sequestration ('enhanced weathering'). While agriculture may offer an existing infrastructure, weathering rate and impacts on soil a...

Long-lived goal reasoning systems that reason over their history confront the bounding problem–the impracticality of reasoning over a large, ever-growing experience-base. This is a problem with some explanation systems that use the history of their observations to inform beliefs about the current state of the world. We propose to apply narrative intelligence (NI), which includes the ability to ...
