Conventional video cameras have limited elds of view which make them restrictive for certain applications in computational vision. A catadioptric camera uses a combination of lenses and mirrors placed in a carefully arranged con guration to capture a much wider eld of view. One important design goal for catadioptric cameras is choosing the shapes of the mirrors in a way that ensures that the co...

F rictional drag steals energy from a moving fluid, but the loss usually becomes greater as the flow goes from smooth, or “laminar,” to turbulent. The onset of turbulence therefore poses a problem for many situations involving fluid flow through a conduit, be it oil in a giant pipeline, blood in a human aorta, or liquid in a heat exchanger. One established solution is to add a small amount of p...

P hysicists have long wondered whether and how isolated quantum systems thermalize—questions that are relevant to systems as diverse as ultracold atomic gases and black holes. Recent theoretical and experimental advances are bringing fresh insight into this line of inquiry. At one extreme, researchers have shown that disorder can fully arrest thermalization in certain isolated many-body quantum...

Viewpoint Microcurrent Electrical Therapy Electricity was first used to treat surface wounds more than 300 years ago when charged gold leaf was found to prevent smallpox scars. 1 Experimental animal wound models demonstrated that electrical intervention results in accelerated healing with skin wounds resurfac-ing faster and with stronger scar tissue formation. 2,3 Moist wounds resurface up to 4...

We propose a new method for synthesizing freeviewpoint images from multiple view videos in soccer stadium. The previous method[1] can synthesize virtual viewpoint images at only intermediate viewpoint between real cameras. The previous method estimates only pixel-wise correspondences between input images for synthesizing virtual viewpoint images without a 3D reconstruction. In this paper, we pr...

SYNOPSIS This document provides a basic design model for service-oriented design. A basic design model is a design model that addresses all concepts in a particular domain, in our case enterprise services, and unifies concepts that are similar. We show that our basic design model is expressive enough to address the concepts from the different viewpoints in web-service development, specifically:...

In this study, we investigated the effect of viewpoint density and speed of motion on perceived smoothness of viewpoint transitions. The effect of viewpoint density was examined for two types of viewer motion: forward and lateral motion. In both cases, we found that perceived smoothness varies with viewpoint density. We also found the number of viewpoints required to maintain a certain level of...

Estimating the viewpoint of objects in images is an important task for scene understanding. The viewpoint estimation accuracy, however, depends highly on the amount of training data and the quality of the annotation. While humans excel at labelling images with coarse viewpoint annotations like front, back, left or right, the process becomes tedious and the quality of the annotations decreases w...

A safety policy defines the set of rules that governs the safe interaction of agents operating together as part of a system of systems (SoS). Agent autonomy can give rise to unpredictable, and potentially undesirable, emergent behaviour. Deriving rules of safety policy requires an understanding of the capabilities of an agent as well as how its actions affect the environment and consequently th...
