Proportional, integral and derivative (PID) control strategy has been widely applied in heating systems in decades. To improve the accuracy and the robustness of PID control, self-tuning radial-basis-function neural network PID (RBF-PID) is developed and used. Even though being popular, during the control process both of PID and RBF-PID control strategy are inadequate in achieving simultaneous high energy-efficiency and good control accuracy. To address this problem, in this paper we develop and report an enhanced self-tuning radial-basis-function neural network PID (e-RBF-PID) controller. To identify the superiority of e-RBF-PID, following works are conducted and reported in this paper. Firstly, four controllers, i.e., on-off, PID, RBF-PID and e-RBF-PID are designed. Secondly, in order to test the performance of the e-RBF-PID controller, an experimental water heating system is constructed for being controlled. Finally, the energy consumption for the four controllers under the three control scenarios is investigated through experiments. The experimental results indicate that in the three scenarios, the developed e-RBF-PID controller outperforms on-off controller as having higher accuracy. Compared to the PID controller, the e-RBF-PID controller has higher speed in control, and the experimental results show that settling time savings is between 12.6% - 49.0%. Most importantly, less control energy consumption is obtained if using the e-RBF-PID controller. It is found that up to 28.5% energy consumption can be saved. Therefore, it is concluded that the proposed e-RBF-PID is capable of enhancing energy efficiency during control process.

GIS Data Integration to Manage Waterlogging Problem on the Eastern Nile Delta of Egypt

引用

International Journal of Geosciences 2013年第4期4卷 680-687页

作者： M. F. kaiser A. El Rayes K. Ghodeif B. Geriesh Geology Department Suez Canal University Ismailia Egypt

Three sets of satellite data were utilized to outline and monitor the waterlogging problems along the Wadi El Tumilate basin. These data include Thematic Mapper image for year 1984, Enhanced Landsat Thematic Mapper image for year 2000 and SPOT-4 image for year 2008. Supervised classification using the maximum likelihood approach has been performed. A number of 6 classes were observed at the study sites including, Niledeposits and cultivated areas, surface water and water logged areas, salt crust, Quaternary playa deposits, fluviatile and lacustrine deposits and Miocene (gypsum and carbonate) deposits. Water logged areas expanded from9.1 km2 inyear 1984 to18.8 km2 inyear 2000 to25.3 km2 inyear 2008, with a rate of0.7 km2/year. At the same time, vegetation cover shows an increase from453 km2 inyear 1984 to719 km2 inyear 2008. The integrated data used by Geographic Information Systems specified factors controlling waterlogging problems, which are: topography, drainage pattern and water flow direction, excess of irrigation water, deficiency of drainage system, presence of impermeable clay lenses and lineaments direction. Groundwater modeling including GMS and MODFLOW programs were processed to manage waterlogging problem. Using of underground tile drain along the eastern portion of Wadi El Tumilate basin and dewatering wells along the western side was recommended to obtain the highest monetary return from the drainage investment.

The effect of weight loss on fasting blood sugars and hemoglobin A1c in overweight and obese diabetics and non-diabetics

引用

Journal of Diabetes Mellitus 2012年第1期2卷 126-130页

BACKGROUND: Diet and exercise are recommended first line treatment for overweight, obese, and diabetic patients with the goal of decreasing weight and improving glycemic control. The goal of this study was to determine the effect that a low calorie diet and behavioral modification program, as implemented by a medically supervised weight loss program, would have on the fasting blood sugar and hemoglobin A1c in overweight or obese diabetic and over-weight or obese non-diabetic participants. METHODS: Charts from 2009 to 2010 were reviewed for 310 diabetic and non-diabetic patients enrolled in the Via Christi Weight Management (VCWM) program in Wichita, Kansas. Data were collected before and after patients underwent a program of meal replacements and weekly physical activity lasting 12 weeks. Variables included pre and post treatment fasting blood sugars, hemoglobin A1c, body mass index, percent body weight lost, and diabetes status. RESULTS: Diabetic participants lost an average of 11.7% of their initial body weight (IBW), and non-diabetic patients lost 12.5% of their IBW over the treatment course. Post-treatment average fasting blood glucose (FBG) decreased in both diabetics and non-diabetics by 15.53 mg/dL and 8.46 mg/dL, respectively (p = 0.08). Diabetic patients experienced a significant decrease of 0.83% from pre to post-treatment in hemoglobin A1c. For diabetic and non-diabetic groups, the changes in FBG were correlated with the change in weight. CONCLUSIONS: Diet and exercise, as prescribed by the VCWM program, is effective in reducing hemoglobin A1c in diabetics and reducing fasting blood sugars in both diabetic and non-diabetic patients.
