美国马萨诸塞州小男孩詹姆斯做梦都想拥有一套乐高"绿宝石午夜火车"玩具。他用了整整两年时间攒够了钱款,却失望地发现这款玩具已经停卖了,而无论是网上的少量存货还是二手转卖,它们的标价对詹姆斯来说都是天文数字。于是小男孩给乐高玩具写了一封信询问,却得知这款玩具已经停产。让人内心温暖的是,在詹姆斯11岁生日时,他收到了乐高悄悄寄来了这份惊喜。你一定想分享詹姆斯的快乐,小男孩脸上欢呼雀跃的表情,是不是也让你感动呢?这让我不禁联想起同样让人内心温暖的一个小女孩。当得知妈妈吃光了她的万圣节糖果时,小女孩红着眼眶,挤出笑容安慰妈妈说:妈妈我不生你的气,我只是有点伤心……吃那么多糖果会让你头痛,你应该多喝水……下一个万圣节我就不会伤心了,但你不能没有跟我商量就吃掉我的糖果,明年我们一起分享好吗?其实这只是父母们的一个万圣节恶作剧,还有很多小朋友也得到了同样的"噩耗",孩子们天真的各种抓狂让人捧腹,还有小女孩的"next Halloween we can share my candy"让人感动。我相信小女孩长大后,她如果听说有个小朋友特别渴望得到心中的"乐高",她也一定会帮助实现。瞧,正能量就是这样传播和积聚的。

In this paper, we consider the analysis, implementation, and application of wideband sources using both seismic and acoustic sensors. We use the approximate maximum likelihood (AML) algorithm to perform acoustic direction of arrival (DOA). For non-uniform noise spectra, whitening filtering was applied to the received acoustic signals before the AML operation. For short-range seismic DOA applications, one method was based on eigen-decomposition of the covariance matrix and a second method was based on surface wave analysis. Two well-known optimization schemes were used to estimate the source locations from the estimated DOAs at sensors of known locations. Experimental estimation of the DOAs and resulting localizations using the acoustic and seismic signals generated by striking a heavy metal plate by a hammer were reported.

The Sunshine Lake/Sunrise Waterway System, located in Southwest Florida （USA） previously experienced extensive and persistent algal blooms, with noxious odors and deep organic-rich sediments. This algal bloom was addressed via a lake-wide dredging project to remove the material from the lake bottom. A contributing factor to the algal bloom is elevated phosphorus in stormwater runoff, likely due to naturally phosphorus-rich geology in the surrounding watershed. Due to the naturally elevated phosphorus supply, excessive nutrient loads will likely continue in the future. An ongoing monitoring program, initiated after the dredging of the lake, determined that a type of algae （Chara sp,） other than that which caused the initial bloom had established itself by October 2015. This plant biomass is considered an alternative destination for incoming nutrient loads, and as such should be managed, rather than eliminated via the use of herbicides. The abundance and nutrient content of the mass of Chara sp. in the lake and waterway was estimated, and the amount of external nutrient load that would be removed from the lake with physical harvesting of Chara sp. was quantified. The cost-effectiveness of nutrient removal via physical harvesting of Chara sp. was then compared against typical stormwater treatment ponds.

This paper presents a holistic methodology for the design of medical device software, which encompasses of a new way of eliciting requirements, system design process, security design guideline, cloud architecture design, combinatorial testing process and agile project management. The paper uses point of care diagnostics as a case study where the software and hardware must be robust, reliable to provide accurate diagnosis of diseases. As software and software intensive systems are becoming increasingly complex, the impact of failures can lead to significant property damage, or damage to the environment. Within the medical diagnostic device software domain such failures can result in misdiagnosis leading to clinical complications and in some cases death. Software faults can arise due to the interaction among the software, the hardware, third party software and the operating environment. Unanticipated environmental changes and latent coding errors lead to operation faults despite of the fact that usually a significant effort has been expended in the design, verification and validation of the software system. It is becoming increasingly more apparent that one needs to adopt different approaches, which will guarantee that a complex software system meets all safety, security, and reliability requirements, in addition to complying with standards such as IEC 62304. There are many initiatives taken to develop safety and security critical systems, at different development phases and in different contexts, ranging from infrastructure design to device design. Different approaches are implemented to design error free software for safety critical systems. By adopting the strategies and processes presented in this paper one can overcome the challenges in developing error free software for medical devices (or safety critical systems).

Based on agricultural nitrogen (N) balance model and field experiments, the impacts of farming system changes of Taihu Region of China on surface water environment were studied. During past 60 years, farming systems changed greatly in Taihu Region. The traditional method of manure collection and application was replaced by chemical fertilizer utilization gradually. Chemical N fertilization intensity decreased greatly due to the abolition of “3 crops per year” and reduction of cropland area in 1990-2010. Crops depleting soil fertility increased, while those improving soil fertility decreased, leading to an excessive dependence on chemical fertilizer application, which increased the risks of soil N loss to surface water environment in Taihu region. However, field experiments showed that the agricultural N loss with runoff only accounted for 2% of fertilizer N application rate. The majority of N was exported by crop harvesting. Our findings showed that the agricultural N loss might not be the main source of N pollution in Lake Tai after 2000. To control N pollution of Lake Tai, more attention should be paid to industrial and domestic wastewater from urban and rural areas, wastes from livestock and poultry breeding, bait input for aquaculture, etc in the Taihu Region, China.
