In situ synthesis of TiC-Al (Ti) nanocomposite powders by thermal plasma technology

A novel processing technology was developed to investigate in situ synthesis of TiC-Al (Ti) nanocomposite powders by thermal plasma technology. Thermodynamic analysis was performed to predict possible starting materials and synthesizing conditions of TiC-Al (Ti) nanocomposite powders. A mathematical model was developed to describe temperature profile and velocity distribution in the reactor. The model is applied to optimize feeding rate, input power, and other processing parameters of TiC-Al (Ti) nanocomposite powders by thermal plasma technology, and to predict which materials can be used as starting materials. This paper emphasizes the investigation of the effect of feeding rate, input power, mole ratio, and other process parameters on synthesis of TiC-Al (Ti) nanocomposite powders by thermal plasma technology. The experimental results showed that TiC-Al (Ti) nanocomposite powders can be synthesized in situ by thermal plasma technology, and the average size of TiC-Al (Ti) nanocomposite powders was less than 100 nm.

Study on phase behavior–impact strength relationship of unsaturated polyester/polyurethane hybrid polymer network

The phase behavior of a hybrid polymer network (HPN) composed of poly[(propylene glycol maleate)-co-(propylene glycol phthalate)] crosslinked with styrene and polyester–urethane crosslinked with methylene-bis-ortho-chloroaniline was examined. The correlation between phase separation and impact strength of the HPNs is discussed. The composition of HPNs has an effect on their properties.

Nonparametric change detection and estimation in large-scale sensor networks

The problem of detecting changes in the distribution of alarmed sensors is considered. Under a nonparametric change detection framework, several detection and estimation algorithms are presented based on the Vapnik-Chervonenkis (VC) theory. Theoretical performance guarantees are obtained by providing error exponents for false-alarm and miss detection probabilities. Recursive algorithms for the efficient computation of test statistics are derived. The estimation problem is also considered in which, after detection is made, the location with maximum distribution change is estimated.
