For years, people have appealed to engineering as the dominant metaphor for how software testing should be done. Yet there are many other metaphors that could provide value to learning about patterns and principles in software testing. As professional testers and nonprofessional musicians, we observe that music affords such a metaphor. What are the parallels between music and testing—especially...

Most statistical concepts and methods can be explained and illustrated using diagrams and in most places where a diagram might be used, a dynamic diagram is more effective than a static one. A few such diagrams per lecture quickly build to hundreds in an introductory statistics course. The collection of CAST applets for lectures contains over 400 including simulations to demonstrate the propert...

When an object casts its shadow on a background surface, the shadow can be informative about the shape of the object, the shape of the background surface and the spatial arrangement of the object relative to the background. Among all these roles, we found that cast shadows were perceptually most relevant for the recovery of spatial arrangement, especially when the shadow is in motion. This find...

The multicast capability and crosstalk issue need to be deliberately considered in the design of future high performance photonic switching networks. In this paper, we focus on the photonic switching networks built on the banyan-based architecture and directional coupler technology. We explore the capability of these networks to support general -cast traffic, which covers the unicast traffic an...

Background: Distal radius fracture is common in the general population. Fracture management includes a plaster cast, splint and synthetic material cast to immobilise the injured arm. Casting complications are common in those conventional casting technologies. 3D printing technology is a rapidly increasing application in rehabilitation. However, there is no clinical study investigating the appli...

The off-loading characteristics of the cast-braces of 30 patients with fractures of the shaft of the femur have been investigated, during axial loading, using strain-gauge transducers. These were applied at the level of the fracture, where the cast was circumferentially split, and to the hinges of the brace at the knee. They measured the load transferred between the two portions of the thigh ca...

Abstract: A direct-chill (DC) cast process of an aluminum ingot of size 3200×1292×320 mm is analyzed numerically by the analysis of a fixed controlled system. The study investigates the DC processes in which liquid aluminum is cooling continuously in mold and then with water spray at the exit of mold. An inverse method is applied to measure heat transfer coefficient on water cooling surface exp...

A corrosion cast of the bronchial arteries provides a useful method of demonstrating their origin and distribution. A cast of the bronchial tree is made at the same time to show the position of the arteries. The cast produced by the method described here is limited to the principal branches of these arteries, the finer terminal twigs being lost. However, as these terminal twigs follow closely t...

Biliary cast syndrome (BCS) is an uncommon complication which is mostly described in orthotopic liver transplantation. However, BCS has also been reported rarely in non-liver transplant patients. We describe a male long-term opium inhaler with BCS who underwent successful endoscopic cast removal by balloon enteroscopy-guided endoscopic retrograde cholangiopancreatography. A 52-year-old man, who...
