What is the area of the shaded region between the tyre tracks of a moving bicycle such as that depicted in Figure 1 ? If the tracks are specified, and equations for them are known, the area can be calculated using integral calculus. Surprisingly, the area can be obtained more easily without calculus, regardless of the bike’s path, using a dynamic visual approach called the method of sweeping tangents that does not require equations for the curves.

Link Congestion

Switch failures can hamper access to client services, cause link congestion and blackhole network traffic. In this study, we examine the nature of switch failures in the datacenters of a large commercial cloud provider through the lens of survival theory. We study a cohort of over 180,000 switches with a variety of hardware and software configurations and find that datacenter switches have a 98% likelihood of functioning uninterrupted for over 3 months since deployment in production. However, there is significant heterogeneity in switch survival rates with respect to their hardware and software: the switches of one vendor are twice as likely to fail compared to the others. We attribute the majority of switch failures to hardware impairments and unplanned power losses. We find that the in-house switch operating system, SONiC, boosts the survival likelihood of switches in datacenters by 1% by eliminating switch failures caused by software bugs in vendor switch OSes.

Course Material

The current research examines whether a visual syllabus aids in information retention compared to a traditional text-based syllabus. The data derive from two lower-division sociology classes, each having a different syllabus format. Utilizing a syllabus quiz during the first week of the class provides the data about whether syllabus format matters. The data suggest the visual syllabus class retained more information given that students exposed to the visual approach scored significantly higher on a quiz than the traditional syllabus class. The current research presents an overview of why visuals may help in information retention with emphasis on the importance of inclusive course material and nontraditional students; an explanation of the data, methods, and analytic procedure followed by the findings; as well as a critical evaluation of and points to consider when creating a visual syllabus.
