‘Real people in real places’: Conceptualizing power for emancipatory security through Tahrir

People, places, things: Web presence for the real world

The convergence of Web technology, wireless networks, and portable client devices provides new design opportunities for computer/communications systems. In the HP Labs’ “Cooltown” project we have been exploring these opportunities through an infrastructure to support “web presence” for people, places and things. We put web servers into things like printers and put information into web servers a...

Real Places in Virtual Spaces

We can distinguish geometrically defined or indicated areas of space from those areas of space where a structure of social norms gives special meaning to movements and actions. A courtroom, a restaurant, a corridor each have their appropriate norms that distinguish sub-areas and assign behaviors to them. We might call such areas places as opposed to mere areas of space that have no special sign...

Robust Real-time People Tracking System for Security

This paper describes an implementation method for the people counting system which detects and tracks moving people using a fixed single camera. This system counts the number of moving objects (people) entering the security door. Moreover, the detected objects are tracked by the proposed tracking algorithm before entering the door. The proposed system with Intel Pentium III operates at an avera...

The Sign-Real Spectral Radius for Real Tensors

In this paper a new quantity for real tensors, the sign-real spectral radius, is defined and investigated. Various characterizations, bounds and some properties are derived. In certain aspects our quantity shows similar behavior to the spectral radius of a nonnegative tensor. In fact, we generalize the Perron Frobenius theorem for nonnegative tensors to the class of real tensors.
