Sensor network can be very beneficial in saving human life from terrorist attacks causing explosion in certain areas leading to casualties. But realization of the sensor network application in explosive detection requires high scalability of the sensor network and fast transmission of the information through real time monitoring and control. In this paper a novel mechanism for explosive trace detection in any populated area by the use of mobile telephony has been described. The aim is to create a system that will assure common men, local population and above all the nation a secured environment, without disturbing their freedom of movement. It would further help the police in detection of explosives more quickly, isolation of suicide bombers, remediation of explosives manufacturing sites, and forensic and criminal investigation. To achieve this, the paper has projected an idea that can combine the strength of the mobile phones, the polymer sensor and existing cellular network. The idea is to design and embed a tiny cog-nitive radio sensor node into the mobile phone that adapts to the changing environment by analyzing the RF surroundings and adjusting the spectrum use appropriately. The system would be capable of detecting explo-sives within a defined territory. It would communicate the location of the detected explosives to the respec-tive service provider, which in turn would inform the law and enforcement agency or Police.展开更多
目的:评价运动处方、普通心理、认知行为和团体辅导这四种不同干预措施对大学生手机依赖的效果。方法:检索PubMed、Web of Science、Embase、知网等数据库,收集四种干预措施对大学生手机依赖的文献,运用Revman5.3和Stata14.2软件进行数...目的:评价运动处方、普通心理、认知行为和团体辅导这四种不同干预措施对大学生手机依赖的效果。方法:检索PubMed、Web of Science、Embase、知网等数据库,收集四种干预措施对大学生手机依赖的文献,运用Revman5.3和Stata14.2软件进行数据分析。结果:共纳入39篇文献,Meta结果显示:与对照组相比,四种干预措施都能够有效减轻大学生手机依赖,均具有统计学意义。SUCRA值的排序结果:运动处方>认知行为>团体辅导>普通心理>无任何干预的对照组。结论:运动处方干预、普通心理干预、认知行为干预和团体辅导干预都能够有效减轻大学生的手机依赖,而相比于其他三种措施,运动处方成为最优措施的可能性最高,其他依次是认知行为干预、团体辅导干预和普通心理干预。展开更多
