Reflections From The Wearable Computing Conference In Toronto, Canada, Nick Rheinberger, Katina Michael, Alexander Hayes Jun 2015

Reflections From The Wearable Computing Conference In Toronto, Canada, Nick Rheinberger, Katina Michael, Alexander Hayes

Alexander Hayes Mr.

Could sports men and women who are monitored using wearable computers actually be playing to a global theatre to ensure the upkeep of their performance benchmarks instead of consciously watching and reacting to what is happening in the game they are playing? What are the social implications of heart rate monitors and GPS units now embedded into player clothing? What were some of the reflections from the IEEE ISTAS13 meeting on Wearable Computers in Every Day Life? What were some of the main messages that you walked away with from that conference? What made the greatest impression on us was …


Social Implications Of Wearable Computing And Augmediated Reality In Every Day Life (Ieee Symposium On Technology And Society, Istas13), Katina Michael Jun 2013

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 …

Many industrial firms seek the systematic reduction of variability as a primary means for reducing production cost and material waste without sacrificing product quality or process efficiency. Despite notable advancements in quality-based estimation and optimization approaches aimed at achieving this goal, various gaps remain between current methodologies and observed in modern industrial environments. In many cases, models rely on assumptions that either limit their usefulness or diminish the reliability of the estimated results. This includes instances where models are generalized to a specific set of assumed process conditions, which constrains their applicability against a wider array of industrial problems. However, …


Electrochemical Explanation For Asymmetric Electrowetting Response, Mehdi Khodayari, Nathan B. Crane, Alex A. Volinsky Jan 2013

Electrochemical Explanation For Asymmetric Electrowetting Response, Mehdi Khodayari, Nathan B. Crane, Alex A. Volinsky

In electrowetting, a droplet/substrate contact angle is modulated by applying a potential difference between the droplet and the substrate. Typically, the droplet potential is changed via an auxiliary electrode dipped in the droplet. Here, it is shown that electrochemical reactions lead to a potential drop on the auxiliary electrode in electrowetting, which degrades the droplet contact angle modulation. The magnitude of this effect depends on the voltage polarity. This problem can be addressed by using a dielectric layer, such as SiO2, which can prevent electrochemical reactions with the electrowetting substrate and the auxiliary electrode.


Study On Effects Of Supply Voltage Asymmetry And Distortion On Induction Machine, Prashanna Dev Bhattarai Jan 2013

Study On Effects Of Supply Voltage Asymmetry And Distortion On Induction Machine, Prashanna Dev Bhattarai

LSU Master's Theses

Performance of induction motor supplied with asymmetrical and nonsinusoidal supply voltages is studied in this thesis. Theory of induction motor is first presented for sinusoidal symmetrical supply voltages. Equations for the torque, losses, currents and efficiency are derived. Appropriate changes are made to apply this theory to induction motors operating at nonsinusoidal and asymmetrical supply voltages. Single phase equivalent circuit of the induction motor is presented for both asymmetrical and nonsinusoidal supply voltages. The equations governing operating characteristics are presented. Machine torque, losses, current and efficiency for asymmetrical and nonsinusoidal supply voltages are compared with the same for sinusoidal symmetrical …
