Hyperbranched polymers, a transitional structure of linear polymers and dendrimers, own many branches on their backbones. Some of the advantages of hyperbranched polymer are lower intrinsic viscosity, improved solubility and easiness in processing, which are originated from their highly branched and globular molecular structure. Stable amorphous film is readily obtainable from the hyperbranched polymers …

Driven by the widespread interest in nanofiber application, solution electrospinning has become a fascinating technique to prepare polymeric fibers. Many related articles and review monographs have already discussed the processing details and the microstructure of electrospun fibers. However, the development of high-temperature electrospinning solutions is still slow. Not only can solution electrospinning …

This research studies the problem of continuous reverse k-nearest neighbor (CRkNN) query processing in road networks. A reverse k-nearest neighbor (RkNN) query returns the data objects that have the query object in the set of their k-nearest neighbors. It is the complimentary problem to that of finding the k-nearest neighbors (kNN) of a query object and …

Modeling and forecasting stock market volatility have been always very crucial issues in the academic and research communities for finance and economy. As we can see, the evidence for predictability has led to various approaches, some of which are theoretically motivated, while others are simply empirical approaches. However, some major related research compared the ability of various members of …
