This paper designs a Flash controller, which helps the FPGA main state-machine to manage a Flash memory chip efficiently. The controller builds its own instruction set. User operates the proposed controller with the system clock of FPGA without caring about the timing sequences required by the Flash. The proposed Flash controller develops its own method for the reorganization and mapping of invalid...
In this paper, a novel approach combining kernel principal component analysis (KPCA) and least square support vector machine (LSSVM) is proposed for HVAC fan machinery status monitoring and fault diagnosis, which combines KPCA for fault feature extraction and multiple SVMs (MSVMs) for identification of different fault sources. KPCA is used as a preprocessor of LSSVM, which maps the original input...
This paper studies the application of artificial immune algorithm to mobile robot path planning inside a specified environment in real time. The biological immune system is firstly analyzed in a relatively deeper and all-sided point of view reflecting the fresh research in biology. Second, the motion characteristic of the car-like autonomous mobile robot is also analyzed. An immunity algorithm adapting...
Due to the rapid technological developments in image/video capturing, huge data storage, video compression and networking, huge amount of video data are produced each day all over the world. Finding effective ways to store, index and retrieve these video remains a hot researching area. It is especially important for the producers/editors of television programs, since to keep track of the 1000's of...
A series of research tasks were carried out to build a model of the printers output. First, various correction methods of Neugebauer equation were analyzed, and put forward a new correction method that is using exponential correction method with considering the impact of dot gain, this model was selected as the forward model and its accuracy was tested throughout the colorant space. It was found to...
Twenty-eight bacterial strains capable of utilizing the petroleum were isolated from coastal areas along Jiaozhou Bay, Qingdao, China. The biodegradation of diesel and crude oil in seawater by mixed cultures of hydrocarbon-degrading bacteria was investigated. The mixtures or consortia of bacteria, denoted as Consortium 1 and Consortium 2 consisted of 5 bacterial strains, respectively. Consortium 1...
To evaluate the influence of the dispersant GM that was widely used in China on the biodegradation of diesel oil spilled in seawater, experiments were done under laboratory conditions at different salinities, temperatures with varied dispersant concentration .The results indicate that the concentration of dispersant added in seawater, seawater salinity and temperature are important factors affecting...
Recent years have shown impressive growth in the development of pervasive healthcare systems, which are primarily being designed to provide emergency and preventive healthcare to citizens anywhere/anytime using wired and wireless mobile technologies. This paper presents an e-healthcare framework with pervasive sensor network for the disabled and elderly people. A home healthcare server collects user...
As the worldpsilas aged population grows many governments are looking to remote healthcare monitoring solutions. With the recent active research activities in the area of Wireless Sensor Networks (WSN), the development and realization of a light-weighted, low-cost and wireless home healthcare monitor has become feasible. A novel embedded remote healthcare system based on a commercially available wireless...
Biodegradability of 5 kinds of industry wastewater (food-processing wastewater, coking plant wastewater, paper mill wastewater, kier wastewater and black liquor in paper industry) was studied using Warburg respirometer and simulated oxidation pond. Results showed a positive correlation exists between the oxygen consumption rate R% and the ratio of BOD5/COD. Treating industrial wastewater by oxidation...
