Multiple single-event transients (MSETs) are evaluated from the perspective of sensitive area. First, a simple model is proposed to analyze the sensitive area of simple logic cells. Based on this simple model, the vulnerabilities of MSETs sensitive areas are then calculated. At last, a layout-level approach is designed to reduce the vulnerabilities of the MSETs sensitive areas. Our simulation r…
Two types of diagnosability of stochastic discrete-event systems (DESs) were introduced by Thorsley et al. in 2005, where a necessary and sufficient condition for Strong Stochastic (SS)-Diagnosability (referred as A-diagnosability by Thorsley and Teneketzis, 2005), and a sufficient condition for Stochastic (S)-Diagnosability (referred as AA-diagnosability by Thorsley and Teneketzis, 2005), bot…
Abstract. At the time when demand for energy is rapidly increasing, the reserves of crude oil are rapidly declining. At the same time an increasing number of new natural gas reserves have been discovered, however, most of them are far away from industrial users and population centers. Because of these large reserves in remote locations, gas transport to user locations is more difficult and …
Abstract. Fe3+ bipyridine complexes were successfully anchored on the inner surface of the mesopores of SBA-15 and compared with those immobilized on the surface of SiO2. FT-IR, ESR, and XAFS measurements were used to characterize the structure of the formed μ–oxo-bridged binuclear Fe bipyridine complexes inside the mesopores of SBA-15, which were observed to be the active species for th…
Abstract. The chain growth probability (α value) is one of the most significant parameters in Fischer–Tropsch (FT) synthesis. To gain insight into the chain growth probability, we systematically studied the hydrogenation and C–C coupling reactions with different chain lengths on the stepped Co(0001) surface using density functional theory calculations. Our findings elucidate the relati…
ABSTRACT This work presents two points with respect to manganese oxide (MnOx) nanomaterials: their controllable synthesis with desired phases and shapes together with their applications as catalysts for oxygen reduction and Al/air batteries. Solid MnOx with crystalline phases of MnOOH, Mn2O3, and MnO2 as well as shapes of the sphere, wire, rod, and particle were prepared through a simple one-…
ABSTRACT Background The ‘Healthy Habits Program’ is a 6-month community-based program, which offers exercise facilities, training and weekly health education group to underserved elderly Chinese Americans with chronic medical diseases in their native languages. This pilot study evaluates the acceptability and the health effects of the ‘Healthy Habits Program’. Methods Ninety-nin…
