基于CVI的红外探测器元件评估系统

设计了一种红外探测器元件性能评估系统,包括黑体,斩波器,单片机控制电路,信号调理电路,高精度数据采集卡,CVI虚拟仪器软件,能够测试红外探测器在特定频率红外照射下的灵敏度和无红外照射下的噪声幅度.噪声的测试采用一次样本采集,快速傅立叶变换分析,得出各个频率的噪声幅度.该系统自动读取计算机系统配置,完成参数初始化,具有操作简单方便、界面友好、测试效率高、可扩展性强、成本低和可靠性高的优点.经过实际测试实验,该系统可方便有效地测试红外探测器性能,实验结果的精度和速度均高于常规方法.     

一种语义嫡的社区划分模型及其应用研究

根据复杂网络中整个网络由若干个社区组成和用户通常只对少数主题感兴趣的事实,通过社区语义墒和社区间语义间嫡,提出了一种基于语义信息的社区结构划分模型,将网络划分为几个语义社区,并将其应用在服务注册中心的具体问题中,同时通过社区负载容量等参数进行了实验分析。实验结果表明,该模型充分考虑到了社区间的语义特性,在应用中效率有显著提高,为语义社区结构中的服务注册中心部署提供了新的途径。

The impact of flood risk on the price of residential properties: the case of England

This paper examines the impact of flood risk on the value of English residential properties. We find that a location within a flood zone significantly lowers property values even if we control for the proximity to a watercourse, the history of flooding and neighbourhoods effects. Although the flood risk discount is more compelling for waterfront properties, it is still highly significant for dwellings further from the water. The markdown arises around 2004–2005, which coincides with the publication of detailed flood maps by the UK Environment Agency and with a more risk-based pricing of flood insurance policies. As expected, the effect of flood risk on house prices is stronger in the months following major flood events but, interestingly, it almost disappears in a hot market when buyers have arguably less negotiating power.     

A preliminary descriptive analysis of Corneal Transplant Registry of National Eye Bank in India

PurposeTo describe and analyze the Corneal Transplant Registry of National Eye Bank and also evaluate graft outcomes in India.MethodsAll patients who underwent corneal transplant at our center within six months of setting up of Corneal Transplant Registry and installation of database at National Eye Bank were included in the study. The established database was analyzed for utilization, donor and recipient details and graft outcomes. Outcome was assessed at the end of one year follow up. The influence of various donor and recipient factors affecting outcome were evaluated. Visual outcome was analyzed in terms of shift in visual handicap category. Statistical tests like analysis of variance, Kruskal–Wallis test and Chi square tests were applied for determination of clinical significance wherever required.Results326 corneas were received from 168 donors; of these, 234 (71.7%) were utilized for transplantation. Out of 177 patients with adequate (one year) follow up (75.6% patients), optical corneal replacement was performed in106 patients and therapeutic keratoplasty in71. 78% (82/106) patients in the optical group retained clear grafts at the end of follow up. 59.7% (49 of 82) of patients who attained clear grafts belonged to visual disability category 3 or worse pre-operatively. 59.1% of these achieved BCVA of ≥6/60 at the end of follow up; thus shifting up their visual handicap category. Primary graft failure was found to be associated with full thickness keratoplasty and not with lamellar procedures (p < 0.05) and occurred in 4.2% patients (5) with optical corneal replacement whereas 7.5% patients (8) developed secondary graft failure. Age of donor (p = 0.54), death enucleation time (p > 0.05), cause of donor death (p = 0.15), type of surgical procedures (p = 0.538) and indication for surgery did not have any significant effect on outcome. 76% patients who underwent therapeutic graft achieved elimination of corneal infection.ConclusionsThe development of corneal graft registry established an effective means to evaluate our corneal transplantation services. Outcomes of sight restoring corneal transplants performed were comparable to results of graft registries from developed nations.
