Comparing Particle Swarms For Tracking Extrema In Dynamic Environments, Xiaodong Li, Hoa K. Dam
Comparing Particle Swarms For Tracking Extrema In Dynamic Environments, Xiaodong Li, Hoa K. Dam
Xiaodong Li
This work presents a comparative study of particle swarm models on their abilities to track extrema in dynamic environments. A standard PSO, two randomized PSOs, and a fine-grained PSO are evaluated in non-trivial multimodal dynamic environments involving small constant step changes, different large step changes, and chaotic step changes of the extrema. DF1 proposed by Morrison and De Jong is used to generate these three types of dynamics (1999). Our results indicate that PSO and its variants are able to perform reasonably well in a 2-dimensional variable space, whereas perform well to a less extent in a 10-dimensional variable space. …
Social Implications Of Wearable Computing And Augmediated Reality In Every Day Life (Ieee Symposium On Technology And Society, Istas13), Katina Michael
Social Implications Of Wearable Computing And Augmediated Reality In Every Day Life (Ieee Symposium On Technology And Society, Istas13), Katina Michael
Associate Professor Katina Michael
It was in July 2012 that Steve Mann and I corresponded on the possibility of hosting a conference on wearable computing in Toronto, Canada. Steve had just returned home from a family holiday to France and publicly blogged about an unfortunate incident that had happened to him while away. On 17th July 2012 he posted: “Physical assault by McDonald’s for wearing Digital Eye Glass”. We both knew the timing was right for such an event that was not just a technical engineering or applied orientation on the theme of smart worlds, but an event that would grapple with the dichotomies …
Location And Tracking Of Mobile Devices: Überveillance Stalks The Streets, Katina Michael, Roger Clarke
Location And Tracking Of Mobile Devices: Überveillance Stalks The Streets, Katina Michael, Roger Clarke
Professor Katina Michael
During the last decade, location-tracking and monitoring applications have proliferated, in mobile cellular and wireless data networks, and through self-reporting by applications running in smartphones that are equipped with onboard global positioning system (GPS) chipsets. It is now possible to locate a smartphone-user's location not merely to a cell, but to a small area within it. Innovators have been quick to capitalise on these location-based technologies for commercial purposes, and have gained access to a great deal of sensitive personal data in the process. In addition, law enforcement utilise these technologies, can do so inexpensively and hence can track many …
Location Privacy Under Dire Threat As Uberveillance Stalks The Streets, Katina Michael, Roger Clarke
Location Privacy Under Dire Threat As Uberveillance Stalks The Streets, Katina Michael, Roger Clarke
Associate Professor Katina Michael
Location tracking and monitoring applications have proliferated with the arrival of smart phones that are equipped with onboard global positioning system (GPS) chipsets. It is now possible to locate a smart phone user down to 10 metres of accuracy on average. Innovators have been quick to capitalise on this emerging market by introducing novel pedestrian tracking technologies which can denote the geographic path of a mobile user. At the same time there is contention by law enforcement personnel over the need for a warrant process to track an individual in a public space. This paper considers the future of location …

The Social And Behavioral Implications Of Location-Based Services, Katina Michael, M.G. Michael
The Social And Behavioral Implications Of Location-Based Services, Katina Michael, M.G. Michael
Associate Professor Katina Michael
The social and behavioral implications of location-based services (LBS) are only now beginning to come to light in advanced markets where the services have been adopted by just a little over half the market (Microsoft 2011). Depending on one’s definition of what constitutes location-based services, statistics on the level of adoption differ considerably. While it is helpful to provide as broad a list of applications as possible in what constitutes LBS (e.g. everything from in-vehicle navigation systems to downloading a map using a computer), it can also cloud the real picture forming behind this emerging technology. Emerging not in the …

The importance of atmospheric odours for homing pigeon navigation in a desert environment was tested using birds from two lofts located in the Sonoran desert near Tucson, Arizona, USA, When released from a familiar training site, experienced control pigeons and pigeons given intranasal injections of zinc sulphate to produce anosmia both displayed good homeward orientation and homed rapidly, When released from two unfamiliar locations, in contrast, the controls continued to display good homing performance while the zinc-sulphate-treated pigeons homed poorly, Significant differences in vanishing bearings, homing time and homing success were recorded, When a group of control and a group …
The Emerging Ethics Of Humancentric Gps Tracking And Monitoring, Katina Michael, Andrew Mcnamee, M G. Michael
The Emerging Ethics Of Humancentric Gps Tracking And Monitoring, Katina Michael, Andrew Mcnamee, M G. Michael
Professor Katina Michael
The Global Positioning System (GPS) is increasingly being adopted by private and public enterprise to track and monitor humans for location-based services (LBS). Some of these applications include personal locators for children, the elderly or those suffering from Alzheimer’s or memory loss, and the monitoring of parolees for law enforcement, security or personal protection purposes. The continual miniaturization of the GPS chipset means that receivers can take the form of wristwatches, mini mobiles and bracelets, with the ability to pinpoint the longitude and latitude of a subject 24/7/365. This paper employs usability context analyses to draw out the emerging ethical …
Location-Based Intelligence – Modeling Behavior In Humans Using Gps, Katina Michael, Andrew Mcnamee, M G. Michael, Holly Tootell
Location-Based Intelligence – Modeling Behavior In Humans Using Gps, Katina Michael, Andrew Mcnamee, M G. Michael, Holly Tootell
Professor Katina Michael
This paper introduces the notion of location-based intelligence by tracking the spatial properties and behavior of a single civilian participant over a two-week study period using a global positioning system (GPS) receiver, and displaying them on a geographic information system (GIS). The paper clearly shows the power of combining speed (S), distance (D), time (T) and elevation (E) data with the exact longitude and latitude position of the user. The issues drawn from the observation and the civilian’s personal diary are useful in understanding the social implications of tracking and monitoring objects and subjects using GPS. The findings show that …
