| 1 | 二维电离室矩阵在放疗的质量保证体系中的应用显示文摘肿瘤的放射治疗中,为了检测治疗设备的性能以及确保放疗计划实施的可靠性和准确性,必须具备完善的质量保证体系(Quality Assurance,QA).本文研究将德国PTW公司研发的二维电离室矩阵Seven29应用到放疗的日常QA过程中,使用Seven29和与之配套的八角体模或平板体模来测量剂量分布图,并与治疗计划系统计算出来的剂量分布图进行比较.对治疗设备每月的QA,最重要的项目是检测射线性能的连续性,检测方法是对连续两个月机器性能的参数进行比较.采用PTW公司的软件Veri Soft和Multi Check进行数据分析,经大量的实验验证和比较,结果表明二维电离室矩阵是剂量测量和分析的有效工具,其精度高、可靠性强、使用方便,是实现无胶片化和无纸化放疗体系的重要组成部分. | 窦一平 Xin Zhang Eun YoungHan Yulong Yan | 2015 | 南京师范大学学报(工程技术版)2015，15，3： | 2 |

| 7 | Adaptive path selection for the improved distributed mobility management显示文摘Current mobility management schemes usually represent centralized or hierarchical architectures,which force data traffic to be processed by a centralized mobility anchor.This allows the mobile node(MN)to be reachable anywhere and provides an efficient method for seamless session continuity.However,all of the signal messages and data traffic converge on particular mobility anchor,which causes excessive signaling and traffic at the centralized mobility anchor and single point of failure issues as data traffic increases.To overcome these limitations and handle increasing data traffic,the distributed mobility management(DMM)scheme has emerged as an alternative solution.Although previous researches have been conducted on DMM support,because their schemes employ an unconditional way to make direct paths after handover,they have some drawbacks,such as several signaling and chain of tunneling problems.Therefore,this paper introduces a new DMM scheme which adaptively creates a direct path.To support it,we present the path selection algorithm,which selects the most efficient path between a direct path and no direct path based on routing hops and traffic load.Through the performance analysis and results,we confirm that the proposed scheme is superior in terms of signaling and packet delivery costs. | Jiwon Jang Seil Jeon Younghan Kim | 2012 | Journal of Measurement Science and Instrumentation2012，3，2： | 0 |
| 8 | Hierarchical wireless network architecture for factory network显示文摘The traditional wired networks in an industrial firm often encounters large difficulties,such as the cable installation,regular maintenance and cable replacement and so on,all these results in high cost.So,in this paper,we propose an IP-based hierarchical wireless network architecture and apply some of the technologies of 6LoWPAN to it.We verify the proposed architecture via real implementation with a wireless backbone,sensor networks and a connection between those networks.And the IP-based hierarchical industrial network is indeed an advanced network for harsh industrial environments. | Sungnam Moom Younghan Kim | 2012 | Journal of Measurement Science and Instrumentation2012，3，2： | 0 |
| 9 | Reactive data collection protocol using mobile sink in wireless sensor network显示文摘We suggest event collection protocol in a specific region where sensors are deployed to detect and collect events.In the traditional multi-hop routing in wireless sensor networks reporting events to a sink node or base-station will cause imbalanced energy consumption of static sensors.To solve this problem,we use mobile sink.In this paper,we study the design of efficiency routing protocol for supporting efficient data collecting in mobile sink wireless sensor networks(mWSNs).We suggest the following two main ideas.First,we use reactive protocol to cut off unnecessary delay.Mobile sink makes a path to access to sensor node.Second,we model mobile sink movement depending on data frequency,so we can reduce moving distance efficiently.We simulate this protocol and compare it with the traditional method.Simulation results show this protocol reduces distance significantly and is suitable for mWSNs with heavy traffic. | Hyunwoo Nam Younghan Kim | 2012 | Journal of Measurement Science and Instrumentation2012，3，2： | 0 |
