Keynote: Fighting Back: Science’s Role in Defending Internet Freedom on an Increasingly Censored Planet
Roya Ensafi, University of MichiganRoom: Main21:00-22:00Abstract: The last decade has seen an alarming spread of network interference and censorship well beyond traditional offenders such as Russia and China. This alarming trend jeopardises Internet freedom for billions of users around the world. To preserve human rights and Internet freedom, the scientific community must step up to bring transparency to such practices, build more effective defensive technologies, and partner with civil society to safeguard users. In this talk, I will share experiences from my work in this critical area as well as highlight key lessons learned and pressing challenges where your expertise and engagement are urgently needed.Bio: Roya Ensafi is an associate professor of computer science and engineering at the University of Michigan, where her research focuses on Internet security and privacy, with the goal of creating techniques and systems to better protect users online. She is particularly passionate about online censorship, geo-discrimination, surveillance, and related threats to Internet freedom. Prof. Ensafi is the founder of Censored Planet, a global censorship observatory. She has studied Russia’s throttling of Twitter, HTTPS interception in Kazakhstan, and China’s Great Cannon attack, among many other instances of network interference. She is a recipient of the Sloan Research Fellowship, NSF CAREER, Google Faculty Research Award, multiple IRTF Applied Networking Research Prizes, and the Consumer Reports Digital Lab fellowship. Her work has been cited in popular publications such as The New York Times, Newsweek, Business Insider, Wired, and Ars Technica.22:00 (July 17)

Abstract
In the usual case, the fall cone test has been used to estimate the undrained shear strength of insensitive remoulded clays. Its concept was based on the critical state soil mechanics and is well established. It is only recently that the use of this simple laboratory equipment has been extended to estimate the shear viscosity of soils which are well below their liquid limit. At these water contents, the viscous strength helps to understand the resistance of soils to flow in penetration tests, pile driving and landslides. This paper reports the results of fall cone tests under different loads. In this study, the effect of water content on shear viscosity was investigated by varying the weight of the cone. All the tests were conducted using speswhite kaolin clay. The samples were thoroughly mixed with water and then kept overnight in air-tight containers to ensure proper mixing of the clay with water. The fall cone apparatus was modified to accommodate an LVDT connected to a high-speed data logger which enabled the cone penetration to be logged at every 0.01 s. The mass of the standard cone was increased by 390 to over 1000 g with the use of stainless steel discs. In some tests, the cone was not permitted to fall freely but was driven at a constant rate of 1.25 mm/min. The load versus penetration resistance measured at different water contents showed that the penetration increased with the increase in LI and at a given load, the results were consistent with the triaxial test results. Shear viscosity was calculated using the rate at which the cone penetrated into the soil and was shown to decrease with the increase in LI .
