For the first time, ultra-high molecular weight polyethylene (UHMWPE) was produced in gas phase process with a new fluidized bed concept where the solids are dispersed phase and the gas is bulk phase as opposed to conventional fluidized bed reactors (FBRs). With this concept, UHMWPE with average molecular weights about 1-6,9 × 10 6 g moles −1 were produced with a commercial supported Ziegler-Natta catalyst by using a gas phase mini semibatch reactor system.

In this paper, we propose a novel software-based system to stabilize camera videos in real-time by combining several general models. The main contribution of proposed system is the capability of processing instantaneously video achieved from moving devices to meet quality requirements by using Harris with Optical-flow, and Lucas-Kanade methods for motion estimation.

The widespread appeal of Hollywood movies is due not only to the studios’ economic power and marketing prowess but also to the formal-aesthetic qualities of the films themselves.

The demand of transmission of images and video is increasing quickly recently and researchers are trying to invest good solutions to improve the quality of these over wireless networks. There are still challenges due to the different characteristics and quality of images between wired and wireless channels. An important issue is congestion control to ensure network stability and achieve a reasonably fair distribution of the network resources among the users.
