The variation in temperature on the island of Gran Canaria is studied using the method applied to the nearby island of Tenerife [1]. An upward warming trend of 0.09°C ± 0.05°C (α = 0.01) was seen from 1946 to date, which has accelerated since the seventies to 0.17°C ± 0.10°C (α = 0.01). The increase was higher at night (0.11°C ± 0.05°C) than by day (0.08°C ± 0.06°C), so the temperature range decreased slightly. These values are similar to those of Tenerife and the time series of anomalies for the two islands are highly correlated. On the coast the same relationship to the sea surface temperature was found as in Tenerife, but in the mid-altitude areas to windward, some differences were detected that are hypothetically attributable to the different relief of the two islands.

正如Rutherford和Heming(1978)所证实的,用热力学方法,对火山岩中常见的斑晶组合,可以测定H-O-S系统中喷发前岩浆挥发组份的丰度。这些方法,可应用于Tenerife(canary岛)、Sao Miguel及Faial(Azores)的大气降落和熔结凝灰岩型的碱性浮岩堆积物。表明由含有可估量的次要元素的钛磁铁矿-钛铁矿矿物对,能获得可靠的温度及 fO_2的估算值。然而在流纹岩岩浆中所见到的 fO_2缓冲机理,在更碱性的液体中似乎不起作用。利用黑云母估算 fH_2O,得出高的 fH_2O值,表明与岩浆有关的强烈爆炸现象是符合的.由磁黄铁矿成分,可估算 fS_2。由气体平衡,可算出 fH_2、fH_2S、fSO_2、fSO_3。从硫组份的数据可很粗略地估算不含黑云母样品的水逸度。在碱性及钙碱性的硅铝质岩浆中,这些组份的丰度是类似的。重视有关爆炸性喷发过程中,挥发物的喷出在火山学上的含义。

通过采用边缘计算技术,可以实现低延迟、实时服务、快速性能和低功耗的要求,云计算不会被边缘计算取,反而边缘计算将与云计算结合。容器编排是实现边缘计算的基础设施。容器编排提供可用性的概念,这也是其主要优点之一。容器编排具有可伸缩性,这意味着它具有高性能,高速加载和响应。容器编排也具有灾难恢复功能,因为它可以根据内容对服务进行划分,所以适合用于跨多个环境和集装箱化微服务处理数十万个容器,第7层负载均衡器是微服务的完美层。本研究的目的是分析和比较Round-Robin、Peak EWMA和canary Deployment行为,本研究实验的目的不仅是研究算法如何平均分配请求,且还将检查延迟和资源使用情况以及应用Brotli算法对速度进行优化。循环(RR)算法是为分时系统明确开发的,并根据请求给每个进程。第二种算法是Peak EWMA算法,选择具有最低指数加权移动平均输出的节点,并保留每个副本的往返时间(Round Trip Time,RTT)的移动平均,金丝雀部署使用多个入口资源根据权重进行流量分割。论文第一部分,根据给定的请求时间和数量检查了不同的场景,总结出循环是划分工作负载和使用最少CPU资源的最有效方法,canary的性能与Round-Robin略有不同,它们非常适合资源有限的机器。将EWMA与竞争的方法进行比较的情况下,EWMA将收到的请求最多,这影响了上游响应时间和资源消耗,此外,通过测量延迟时间,证实了Peak EWMA算法是鲁棒性最强、速度最快的算法。该算法消耗的资源更少,因为EWMA的执行时间比其他算法更短。本研究发现,与数量较多的pods相比,数量较少的pods可以创建更多的请求、更少的错误和更快的性能。因此,管理集群取决于特定的情况,而不是优先考虑高可用性或考虑集群的资源。

The Unlink attack is a way of attacking the heap overflow vulnerability under the Linux platform. However, because the heap overflow data seldom directly leads to program control flow hijacking and related protection mechanism limitations, the existing detection technology is difficult to judge whether the program meets the heap overflow attack condition. There are certain inspection measures in the existing unlink mechanism, but with carefully constructing the contents of the heap, you can bypass the inspection measures. The unlink mechanism must be triggered with the free function, and this principle is similar to function-exit of stacks. The paper obtains the inspiration through the canary protection mechanism in the stack, adds it to the chunk structure, encrypts the canary value, and defends the unlink attack from the fundamental structure. The experimental results show that this method can effectively prevent the occurrence of unlink attacks and has the ability to detect common heap overflows.

Currently, only a few states in the U.S. (e.g. Colorado and Ohio) require mandatory baseline groundwater sampling from nearby groundwater wells prior to drilling a new oil or gas well. Colorado is the first state to regulate groundwater testing before and after drilling, requiring one pre-drilling sample and two additional post-drilling samples within 6 - 12 months and 5 - 6 years of drilling, respectively. However, the monitoring method is limited to ex-situ sampling, which offers only a snapshot in time. To overcome the limitations and increase monitoring effectiveness, a new groundwater monitoring system, Colorado Water Watch (CWW), was introduced as a decision-making tool to support the state’s regulatory agency and also to provide real-time groundwater quality data to both industry and the public. The CWW uses simple in-situ water quality sensors based on surrogate sensing technology that employs an event detection system to screen the incoming data in near real-time. This objective of this study was to improve the understanding of groundwater quality in Wattenberg field and assess event detection methods. The data obtained from 5 sites (the earliest monitoring sites in the CWW network) for 3 years of the regional monitoring network in Wattenberg field is used to illustrate the background information about groundwater quality and its changing trend, and make comparisons between two outlier detection methods, canary and simple moving median.
