Argumentation Logic
(2014)We propose a novel logic-based argumentation framework, called Argumentation Logic (AL), built upon a restriction of classical Propositional Logic (PL) as its underlying logic. This allows us to control the application of ...

Brief announcement: On the robustness of (semi)fast quorum-based implementations of atomic shared memory
(2008)Atomic (linearizable) read/write memory is a fundamental abstractions in distributed computing. Following a seminal implementation of atomic memory of Attiya et al.[6], a folklore belief developed that in messaging-passing ...

Simulations of nanoscale Ni/Al multilayer foils with intermediate Ni2Al3 growth
(2015)Nanoscale multilayers of binary metallic systems, such as nickel/aluminum, exhibit self-propagating exothermic reactions due to the high formation enthalpy of the intermetallic compounds. Most of the previous modeling ...

Spark ignitable Ni-Al ball-milled powders for bonding applications
(2014)Ball milling of aluminum (Al) and nickel (Ni) particles at the NiAl composition can produce reactive powders with low spark ignition thresholds similar to magnetron sputtered multilayer foils (MFs). Such powders can replace ...

Sulfur doping of M/In2O3 (M=Al,W) nanowires with room temperature near infra red emission
(2015)We have investigated the growth of Al doped In2O3 nanowires via the vapor-liquid-solid mechanism at 800°C using Au as a catalyst. We find that the Al is not incorporated into the cubic bixbyite crystal structure of In2O3 ...
