But when we directly use it in the process of reconstruction, there are some problems, such as the large calculating quantity and poor denoising ability, etc. This paper puts forward a new method to solve the problems of the Power Crust algorithm. In stage I, we use the KD tree algorithm to get every point’s neighborhood information within the points cloud. In stage II, we use the Laplace method to denoise the points sets. In stage III, we use the neighborhood average method to simplify the points sets when the points are too many. At last, we use the Power Crust algorithm to accomplish the reconstruction. The result is a 3D model constructed from the simplifying points sets. In addition, compared with the previous method, this paper’s method systematically solves the denoising problem and simplifies the points cloud. It has a fast reconstruction speed and a good reconstruction model. Read More Read Less

Abstract An abstract model of the logical relationship among the alarm and algorithm based on hierarchical priority alarm correlation inference rules are proposed by analysis of existing alarm correlation needs. The algorithm clearly describes the relationship and alarm, and can be flexibly combined multi-part configured to expand coverage area of the algorithm rules. It is in favor of knowledge... An abstract model of the logical relationship among the alarm and algorithm based on hierarchical priority alarm correlation inference rules are proposed by analysis of existing alarm correlation needs. The algorithm clearly describes the relationship and alarm, and can be flexibly combined multi-part configured to expand coverage area of the algorithm rules. It is in favor of knowledge update in change process of the network structure. Read More Read Less

It is necessary to diminish the reliance on fresh water consumption to produce dyeing fabric in textile industries. A semi structured questionnaire used to address water risk, current status and best practices of 21 factories of Gazipur district of Bangladesh. 50 mid and top level employees were interviewed during March – August 2015. 67% of survey factories were dependent on ground water and 95% of factories mentioned that water was easily available. There was no water conservation system available in 92% of factories however 70% of surveyed factories mentioned that they faced continuous challenges to extract ground water due to nearest factories. Metrological information of study area explicated that significant amount of precipitation recorded over the decades and no significant variation noted in recent years. However, there was a sharp declination of ground water level noted since 1998 which represented the excessive water extraction due to rapid industrialization. 1 of 21 factories introduced rainwater conservation system and used rainwater during the monsoon season. This initiative assisted them to save US$ 1440 annually. Considering the economical and environmental benefits, it is necessary to introduce the rainwater conservation facility in textile industries.
