Aiming at the problems of the dimension of fault feature data sets of the rotating machinery are too high and labeled information of the sample is insufficient, which lead to fault recognition too difficult. A kind of combinational method of fault identification of rotating machinery based on Kernel Semi-supervised Orthogonal Marginal Fisher Analysis (Kernel Semi - Supervised Orthogonal Marginal Fisher...
Urbanization is nowadays a global issue, and the encroachment of urban on non-urban land, especially arable land, has become a common phenomenon in most developing countries. For instance, Chinese coastal zone has witnessed incredibly rapid urban and industrial development since 1978. In order to explore the urbanization progress of China, the paper utilized an interactive visual interpretation method...
A kind of haze removal algorithm is proposed, so as to improve the visibility of degraded image with only single image. Firstly, the raw atmospheric transmission map is obtained using the dark channel prior. Then, Fields of Experts model with guided filtering is integrated to get the priors from the degraded image, so as to amend the raw atmosphere transmission map. Finally, the scene albedo is restored...
We consider a two-machine shop scheduling problem in which the jobs are from two agents and each job has a time-dependent proportional deteriorating processing time. The two agents compete for a common two-machine shop setting to process their own jobs. Each agent has its own criterion to optimize. Three shop settings are investigated: flow-shop, open-shop and job-shop. For each setting, the goal...
We study a single-machine scheduling problem where the processing times of jobs simultaneously have the time-dependent deteriorating and the job-dependent learning effects under a deteriorating machine maintenance consideration. We consider four different performance measures. For the first three problems with the objectives of minimizing the makespan, minimizing the total completion time and minimizing...
Based on the investigation data of mercury (Hg) in waters in Jiaozhou bay during time periods of 1979 to 1985 (absent of 1984), in the spatial scale, by means of the analysis of the annual Hg dataset, by the view of the content, horizontal and vertical distribution and season of the Hg, studying the source, water quality, distribution and transfer of the Hg in the marine waters of the Jiaozhou bay...
Controlled surface wrinkling could provide ordered and hierarchical structures in micro- and nano-meter scale. Here combined influence of out-of-plane compressive stress and in-plane substrate relief in Au/PDMS bilayer system was experimentally investigated to explore morphological evolution of surface wrinkling. Compared with single influence from out-of-plane compression or in-plane relief, the...
Unused land has changed rapidly over the past 30 years, resulting in its ecological environment changes as well. The mathematical methodology, which includes dynamic degree index model, spatial density model, change intensity model, conversion matrix, and index model of ecological effects, was developed for studying spatial pattern changes of unused land and the ecological effect caused by unused...
In the last two decades, the rapid economic development and constant rise of urbanization level and relevant policies resulted in a dramatic expansion of built-up lands in China and in different expanding stages. The present study monitored built-up land information by using remote sensing and GIS technology, and analyzed its evolution process. This study will be beneficial in understanding the characteristics...
the objective of this paper is to study the spatial distribution of the Aridity Index in China during the period 1991-2000. Besides, the arid and humid is classified based on the Thornthwaite method, with the help of the climatic data including the monthly precipitation and temperature from 193 meteorological stations. The results showed that the temperature and precipitation was decreasing from the...
The objective of this paper is to identify a suitable coating material in order to tune the microwave radiation and produce absorption losses for Wi-Fi devices. It is also desirable to obtain high absorption losses outside the Wi-Fi microwave frequency range of 2.4 GHz. Literature reviews of several types of material are described and compared for the use of the selected material in order to coat...
A band-pass frequency selective surface (FSS) which is designed on energy saving glass (ESG) with a layer of hard coating to improve the transmission of RF/Microwave signals through modern buildings is presented. A square loop and top loaded cross dipoles FSSs are combined to produce a dual band-pass filter, to improve the transmission of the most common UMTS and Wi-Fi signals, while maintaining the...
Contents of polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers(PBDEs) from twenty municipal sludge samples of wastewater treatment plants (WWTPs)of the Jiangsu Province in China were determined by gas chromatography-mass spectrometry (GC-MS). The results show that 20 Sludge samples contain polybrominated diphenyl ethers and polybrominated biphenyls; Polybrominated diphenyl ethers range...
This paper presents a dual-bandpass (DBP) frequency selective surface (FSS) based on hard-coating energy saving glass (ESG). The objective of this study is to generate a novel design of FSS on ESG, which is to be used for future energy smart buildings at Edith Cowan University (ECU). The ESG is made of a transparent coating of conducting layer on glass substrate, which attenuates infrared (IR) radiations...
Great land use change has taken place in most regions worldwide and such information is urgently needed to help the mankind with rational land use and development. In this paper, land use and change for Xinxiang City in Henan Province of China were analyzed in 1995, 2000 and 2005 by using a series of Landsat Thematic Mapper (TM) satellite data. And spatiotemporal characteristics analysis of land use...
A method of achieving background is presented which detect the moving object with statistics from complex scene. Compared with other methods of achieving image background, this approach can achieve and update simultaneously background. The method of moving object detection has the advantages of simplicity in computation, strong resistance to noise. The state transition matrix and observation matrix...
With the development of remote sensing techniques, RS had become an effective way to do the disaster monitoring and assessment. Nowadays, remote sensing plays an important role in disaster mitigation. But the methods to produce the main product of remote sensing data - image maps, are very complicated, and varies work flows, lot of image processing and operations are included. The requirement for...
Nowadays natural disasters especial earthquakes frequently occur all over the world. Thus rapid mapping of remote sensing system has practical significance. In this paper, based on the methods of disastrous expression of multi-scale geographic maps and remote sensing images, processes of fast mapping were proposed and researched. It includes quick match of base map database and disastrous thematic...
The disaster information mapping templates developed according to the distribution of the earthquake and the secondary disasters can improve the thematic mapping efficiency. It can also provide accurate disaster information of disaster and affected body quickly. First, Disaster special subject sign database should be designed, including disaster category symbols, loss assessment category symbols,...
Based on logarithmic mean Divisia index method I and II, the factors impacting the changes of Chinese industrial SO2 emission intensity are decomposed into SO2 production intensity effect, government control effect (policy effect) and industrial structural effect. Using data of 1998 to 2006, result shows that the main driver behind the reduction of SO2 emission intensity is SO2 production intensity,...
