The bag of visual words (BOW) model has been widely applied in the field of image recognition and image classification. However, all scale-invariant feature transform (SIFT) features are clustered to construct the visual words which result in a substantial loss of discriminative power for the visual words. The corresponding visual phrases will further render the generated BOW histogram sparse. In...
This paper aims to make the sales company achieve maximum profits. It presents a mathematical model, in which we analyze the natural gas pipeline system, consider many factors (compressor stations, the volatility of users' gas consumption, the ability of the end segment of pipe's storage) in transmission and use the end segment of pipeline to store gas. Then, we use nonlinear programing algorithm...
This paper describes a mathematical model for natural gas pipeline network which can help the sales company achieve maximum economic profits. In this paper, we analyze the pipeline network and consider many factors, including the end segment of pipeline for storage. Then we choose the feasible direction algorithm for constrained nonlinear programming to solve the model. At the end of this paper, we...
