A New Insight into Land Use Classification Based on Aggregated Mobile Phone Data [PDF]

open access: yesarXiv, 2013
Land use classification is essential for urban planning. Urban land use types can be differentiated either by their physical characteristics (such as reflectivity and texture) or social functions. Remote sensing techniques have been recognized as a vital method for urban land use classification because of their ability to capture the physical ...

Do Cell Phones Cause Cancer? [PDF]

open access: yesSkeptic magazine, Vol. 15, No. 4, 2010, 2010
Do cell phones, household electrical power wiring or appliance, or high voltage power lines cause cancer? Fuggedaboudit! No way! When pigs fly! When I'm the Pope! Don't text while you're driving, however, or eat your cell phone. All organisms absorb microwave radiation directly as thermal energy.

Investigating population dynamics of the Kumbh Mela through the lens of cell phone data [PDF]

open access: yesarXiv, 2015
The Kumbh is a religious Hindu festival that has been celebrated for centuries. The 2013 Kumbh Mela, a grander form of the annual Kumbh, was purportedly the largest gathering of people in human history. Many of the participants carried cell phones, making it possible for us to use a data-driven approach to document this magnificent festival.

Point Process Models for Distribution of Cell Phone Antennas [PDF]

open access: yesarXiv, 2018
We introduce a model for the spatial distribution of cell phone antennas in a urban environment. After showing that the complete spatial randomness (homogeneous Poisson distribution) hypothesis does not hold, we propose a model in which each point is distributed according to a bivariate Gaussian variable with mean given by the barycenter of its ...

Drivers’ Addiction Toward Cell Phone Use While Driving

open access: yesHealth in Emergencies & Disasters Quarterly, 2018
Background: The use of a cell phone when driving has been recognized as a type of distraction worldwide. Addictive tendency to use technology, including cell phone use while driving may be a substantial problem for drivers and increasing risk of ...

Energy Balance in Cell Phone Radiofrequency Radiation Exposed Mice and Rats [PDF]

open access: yesarXiv, 2019
The National Toxicology Program exposed mice and rats to cell phone radiofrequency radiation. They observer cancers in male rats but not in male mice and different increases in body temperature between mice and rats using identical frequency and intensity exposures.

Total Array Gains of Millimeter-Wave Mobile Phone Antennas Under Practical Conditions [PDF]

open access: yesPublication in 2018 IEEE 87th Vehicular Technology Conference (VTC Spring 2018), Porto, Portugal, June 2018, 2018
This paper studies a gain of an antenna array embedded on a mobile device operating at a millimeter-wave radio frequency. Assuming that mobile phones at millimeter-wave range operate with a single baseband unit and analog beamforming like phased arrays, we define a total array gain denoting a path gain of the phased antenna array in excess to the omni ...
