an evidence based estimate of the appropriate radiotherapy Utilization Rate for colorectal cancer
International Journal of Radiation Oncology Biology Physics, 2003Co-Authors: Farshad Foroudi, Scott Tyldesley, Lisa Barbera, Jenny Huang, William J MackillopAbstract:Purpose: Current estimates of the proportion of cancer patients who will require RT are based almost entirely on expert opinion. The objective of this study was to estimate the proportion of incident cases of colorectal cancer that should receive RT using an evidence-based approach. Methods and Materials: A systematic review of the literature was undertaken to identify indications for RT for colorectal cancer, and to ascertain the level of evidence that supported each indication. An epidemiologic approach was then used to estimate the incidence of each indication for RT in a typical North American population of colorectal cancer patients. The effect of sampling error on the estimated appropriate Rate of RT was calculated mathematically, and the effect of systematic error was estimated by sensitivity analysis. Results: It was estimated that 23.7% 1.0% of colorectal cancer cases develop one or more indications for RT at some point in the course of the illness: 20.9% 1.1% as part of their initial treatment, and 2.8% 0.5% later for recurrence or progression. We estimated that 7.1% 0.8% of colon carcinoma patients will require RT at some point in the course of the illness: 4.0% 0.7% as part of their initial treatment, and 3.1% 0.4% later for recurrence or progression. We estimated that 72.3% 1.0% of rectal carcinoma patients will require RT at some point in the course of the illness: 69.6% 0.9% as part of their initial treatment and 2.7% 0.2% later for recurrence or progression. Conclusions: This method provides a rational starting point for the long-term planning of radiation services, and for the audit of access to RT at the population level. By completing such evaluations in the major cancer sites, it will be possible to estimate the appropriate RT treatment Rate for the cancer population as a whole. © 2003 Elsevier Inc.

evidence based estimate of appropriate radiotherapy Utilization Rate for prostate cancer
International Journal of Radiation Oncology Biology Physics, 2003Co-Authors: Farshad Foroudi, Scott Tyldesley, Lisa Barbera, Jenny Huang, William J MackillopAbstract:Abstract Purpose : Current estimates of the proportion of cancer patients who will require radiotherapy (RT) are based almost entirely on expert opinion. The objective of this study was to use an evidence-based approach to estimate the proportion of incident cases of prostate cancer that should receive RT at any point in the evolution of the illness. Methods and Materials : A systematic review of the literature was undertaken to identify indications for RT for prostate cancer and to ascertain the level of evidence that supported each indication. An epidemiologic approach was then used to estimate the incidence of each indication for RT in a typical North American population of prostate cancer patients. The effect of sampling error on the estimated appropriate Rate of RT was calculated mathematically, and the effect of systematic error using alternative sources of information was estimated by sensitivity analysis. Results : It was estimated that 61.2% ± 5.6% of prostate cancer cases develop one or more indications for RT at some point in the course of the illness. The plausible range for this Rate was 57.3%–69.8% on sensitivity analysis. Of all prostate cancer patients, 32.2% ± 3.8% should receive RT in their initial treatment and 29.0% ± 4.1% later for recurrence or progression. The proportion of cases that ever require RT is risk grouping dependent; 43.9% ± 2.2% in low-risk disease, 68.7% ± 3.5% in intermediate-risk disease; and 79.0% ± 3.8% in high-risk locoregional disease. For metastatic disease, the predicted Rate was 66.4% ± 0.3%. Conclusion : This method provides a rational starting point for the long-term planning of radiation services and for the audit of access to RT at the population level. By completing such evaluations in major cancer sites, it will be possible to estimate the appropriate RT Rate for the cancer population as a whole.

International Journal of Radiation Oncology Biology Physics, 2002Co-Authors: Farshad Foroudi, Scott Tyldesley, Hugh Walker, William J MackillopAbstract:Abstract Purpose: Current estimates of the proportion of cancer patients who will require radiotherapy (RT) are based almost entirely on expert opinion. We sought to use an evidence-based approach to estimate the proportion of incident cases of breast cancer that will require RT at any point in the evolution of the illness. Methods and Materials: We undertook a systematic review of the literature to identify indications for RT for breast cancer and to ascertain the level of evidence that supported each indication. An epidemiologic approach was then used to estimate the incidence of each indication for RT in a typical North American population of breast cancer patients. The effect of sampling error on the estimated appropriate Rate of RT was calculated mathematically, and the effect of systematic error was estimated by sensitivity analysis. Results: It was estimated that 66.4% ± 4.8% of breast cancer patients develop one or more indications for RT at some point in the course of the illness. The plausible range for this Rate was 56.3%–72.4% on sensitivity analysis. Of all breast cancer patients, 57.3% ± 4.7% require RT in their initial treatment and 9.1% ± 1.0% do so later for recurrence or progression. The proportion of patients who ever require RT is stage dependent: 39.8% ± 1.1% in ductal carcinoma in situ ; 68.6% ± 4.1% in Stage I invasive carcinoma; 81.5% ± 2.3% in Stage II; 95.3% ± 0.3% in Stage III; and 63.7% ± 0.3% in Stage IV. Conclusion: This method provides a rational starting point for the long-term planning of RT services and for the audit of access to RT at the population level. By completing such evaluations in the major cancer sites, it will be possible to estimate the appropriate RT treatment Rate for the cancer population as a whole.

the reasonable range of life cycle Utilization Rate of distribution network equipment
IEEE Access, 2018Co-Authors: Linhao Ye, Zhuangli Hu, Canbing Li, Yongjun Zhang, Shiyao Jiang, Zhiqiang Yang, Di ZhangAbstract:The Utilization Rate of power equipment plays a decisive role in the economic operation of power utilities. By determining the reasonable range of life cycle Utilization Rate of the distribution network equipment, it is of great significance to the management of the distribution network equipment. In this paper, the reasonable range of the life cycle Utilization Rate of distribution network equipment is determined. The life cycle Utilization Rate of distribution network equipment depends on the burden Rate, load Rate, and life expectancy Rate, whose reasonable values are analyzed and exemplified, respectively. The optimal model of the burden Rate in different conditions is established. The different load characteristic curves are also given by sorting out the load data. The calculation method of the life expectance Rate is presented in this paper. The reasonable range of the life cycle Utilization Rate is finally obtained by defining the boundary condition of its composition. By setting the reasonable range of life cycle Utilization Rate of the distribution network equipment, power utilities can improve efficiency.

Study on Novel Topology of Solar–Wind Hybrid Power Plant Using Photovoltaic Cell Emulating System
Journal of Electrical Engineering & Technology, 2019Co-Authors: Vu Minh Phap, Nguyen Thuy Nga, I. Mizoguchi, Naoki Yamamura, Muneaki Ishida, T. YamashitaAbstract:At the present, the grid-tied solar power system is the most promising as a renewable energy technology for replacing the fossil energy sources. The usage efficiency of the power conditioner system in the grid-tied solar power system is not high because the electricity generation from solar panels depends on the weather. The Utilization Rate of the power conditioner system can be increased by adding the small scale wind turbine to the existing grid-tied solar power system. We introduced a novel design solution in the previous study to connect the small wind turbine with the power conditioner system of the grid-tied solar power system by emulating technical characteristics of the solar panel in series connection mode. By which, the Utilization Rate of the power conditioner system has been increased. However, this improved Utilization Rate of the power conditioner system is not high in the cloudy and rainy days because the voltage of the solar panel changes slightly and the maximum input voltage of the power conditioner system is limited. Therefore, we propose a novel performance enhancement method for solar–wind hybrid power plant using photovoltaic cell emulating system in this research.

2016 IEEE International Conference on Sustainable Energy Technologies (ICSET), 2016Co-Authors: Vu Minh Phap, Naoki Yamamura, Junji Hirai, Muneaki Ishida, Nguyen Thuy NgaAbstract:The Utilization Rate of the power conditioner in the grid-tied solar power system is low because the operation of photovoltaic (PV) cell depends on the sunlight. Adding the small scale wind power generating system to the existing solar power system can increase the Utilization Rate of the power conditioner. In this paper, we propose a novel design method by which the small scale wind power generating system can connect to the grid-tied power conditioner of solar panel and hybrid power system can transmit power to the utility grid.
