云计算视角下可验证计算的分析研究

云计算能否在未来的各个领域中被广泛运用,决定因素在于其可信度。可验证计算在检测云计算结果的可信度方面具有其独特优势。利用可验证计算协议可验证云服务器端所返回的数据是否正确,它成为实现云计算可信度的重要保障。文中在阐述可验证计算基本内容和相关设计原则的基础上,分析了可验证计算协议的一般流程、设计原则及计算模型,并结合基于交互系统的可验证计算协议分析,探讨在云计算视角下可验证计算的研究展望。     

Fuzzy Views on Black-Litterman Portfolio Selection Model

In this paper, views of investor are described in fuzzy sets, and two fuzzy Black-Litterman models are constructed with fuzzy views and fuzzy random views respectively. In the models, expected returns and uncertainty matrix of views are redefined and the views are formulated by fuzzy approaches suitably. Then the models are tested with data from Chinese financial markets. Empirical results show that the fuzzy random views model performs the best, and both the fuzzy models are better than the traditional ones, demonstrating that the fuzzy approaches can contain more information in the views and measure the uncertainty more correctly.

Aristotle Said “Happiness is a State of Activity” — Predicting Mood Through Body Sensing with Smartwatches

We measure and predict states of Activation and Happiness using a body sensing application connected to smartwatches. Through the sensors of commercially available smartwatches we collect individual mood states and correlate them with body sensing data such as acceleration, heart rate, light level data, and location, through the GPS sensor built into the smartphone connected to the smartwatch. We polled users on the smartwatch for seven weeks four times per day asking for their mood state. We found that both Happiness and Activation are negatively correlated with heart beats and with the levels of light. People tend to be happier when they are moving more intensely and are feeling less activated during weekends. We also found that people with a lower Conscientiousness and Neuroticism and higher Agreeableness tend to be happy more frequently. In addition, more Activation can be predicted by lower Openness to experience and higher Agreeableness and Conscientiousness. Lastly, we find that tracking people’s geographical coordinates might play an important role in predicting Happiness and Activation. The methodology we propose is a first step towards building an automated mood tracking system, to be used for better teamwork and in combination with social network analysis studies.     

基于语料库的中国理工科大学生英语口语手势的使用研究

以中国理工科大学生为研究对象,运用语料库分析法和统计工具,对英语口语中使用手势的情况进行了研究,探讨在口语中手势的使用特点及形成原因。研究发现,英语水平越高的学生越多使用辅助言语表达的手势,水平较低的学生使用适配性手势时持续时间更长;不同性别学生的手势使用情况无显著差异。

工业用PET及PA纤维模量-应变曲线的分析

通过拉伸试验数据得到应力—应变曲线和模量-应变曲线可以更全面地反映纤维的力学性能。PET及PA的模量—应变曲线都是明显的双峰曲线。结合拉伸过程中PET纤维内部结构的变化解释PET纤维的特征模量—应变曲线，并讨论如何提高持续使用应变范围的模量问题。PET模量—应变曲线上的第一个模量峰为初始模量，标志着无定形区缠结网的破坏；无定形区蜷曲大分子伸直时模量较低，导致出现模量低谷；由于伸直的缚结大分子模量较高，出现了第二个模量峰。
