Magnitude estimation of perceived distance over various distance ranges

Distance Estimation between Transceivers over Short Distances

Three methods for determining distances between a user and a fixed coordinate system are considered. One system is based on 802.11g packet communications, another on HF radio carrier frequency interference, and the final system on a signal transmitted over a radio channel. Emphasis is placed on the use of these systems in indoor, building-sized environments. Tests are performed to examine the e...

Social Distance Increases Perceived Physical Distance

Proximity, or spatial closeness, can generate social closeness—the closer people are together, the more they interact, affiliate, and befriend one another. Mediated communication allows people to bridge spatial distance and can increase social closeness between conversational partners, even when they are separated by distance. However, mediated communication may not always make people feel clos...

A Methodology for Magnitude-based Inter-AS Distance Estimation

The relationships among autonomous systems (ASes) can be categorized into three types: 1) transit, 2) peering and 3) sibling. Since customer ASes purchase the Internet access from provider ASes over transit links and any two ASes can exchange their traffic without any payment over peering links, transit links cost more than peering links from the economical point of view. We propose an inter-AS...

An iterative approach for estimation of efficiency by weighted distance

Order of Magnitude Comparisons of Distance

Order of magnitude reasoning | reasoning by rough comparisons of the sizes of quantities | is often called \back of the envelope calculation", with the implication that the calculations are quick though approximate. This paper exhibits an interesting class of constraint sets in which order of magnitude reasoning is demonstrably fast. Speci cally, we present a polynomial-time algorithm that can ...
