a series of polystyrene hybrid nanocomposites have been fabricated with varying amounts of tio2 viz., 0, 0.5 and 1 % w/w along with 3% ts by in-situ polymerization method. the influence of surface modified tio2 nanoparticles on the thermal properties of ps matrix was examined using thermogravimetry and differential scanning calorimetry. thermal characteristics of the polystyrene/ts/tio2 hybrid ...

To avoid unnecessary accident and to insure that overhead transmission lines operate safely, on-line monitoring operation state and dynamic security evaluation are necessary. Dynamic Line Rating (DLR) system has been introduced in monitoring the real-time weather and line conditions. The conductor temperature in operation is affected by complex components. This paper analyzed the characteristic...

maleic anhydride (man) copolymers with methyl methacrylate(mma), ethyl methacrylate(ema), methyl acrylate(ma), ethyl acrylate (ea) and buthyl acrylate (ba) ( in a 1:1 mole ratio) were synthesized by free radical polymerizations method under vacuum -azobis(isobutironitrile)(aibn) as an initiator of reaction at 701c. the copolymer compositions were determined using related 1h nmr spectra techni...

We consider the problem of dynamically rating sports teams based on the categorical outcome of paired comparisons such as win draw and loss in football Our modelling framework is the cumulative link model for ordered response where latent parameters represent the strength of each team A dynamic extension of this model is proposed with close connections to nonparametric smoothing methods As a co...
