Asynchronous Ultrasonic Trilateration For Indoor Positioning Of Mobile Phones, Viacheslav Filonenko (Thesis)
Asynchronous Ultrasonic Trilateration For Indoor Positioning Of Mobile Phones, Viacheslav Filonenko (Thesis)
Theses
Spatial awareness is fast becoming the key feature on today‟s mobile devices. While accurate outdoor navigation has been widely available for some time through Global Positioning Systems (GPS), accurate indoor positioning is still largely an unsolved problem. One major reason for this is that GPS and other Global Navigation Satellite Systems (GNSS) systems offer accuracy of a scale far different to that required for effective indoor navigation. Indoor positioning is also hindered by poor GPS signal quality, a major issue when developing dedicated indoor locationing systems. In addition, many indoor systems use specialized hardware to calculate accurate device position, as …

This paper describes a mathematical model of a low approach open evaporative cooling tower for the production of high temperature indirect cooling water (14-16°C) for use in building radiant cooling and displacement ventilation systems. There are several potential approaches to model evaporative cooling, including: the Poppe method, the Merkel method and the effectiveness-NTU (ε-NTU) method. A common assumption, applied to the Merkel and ε-NTU methods, is that the effect of change in tower water mass flow rate due to evaporation is ignored, which results in a simpler model with reduced computational requirements, but with somewhat decreasedaccuracy. In this paper, a …
Idiosyncratic Distances: Impact Of Mobile Technology Practices On Role Segmentation And Integration, Nicolas Battard, Vincent Mangematin
Idiosyncratic Distances: Impact Of Mobile Technology Practices On Role Segmentation And Integration, Nicolas Battard, Vincent Mangematin

Mobile technologies have brought convenience, flexibility and connectedness in our lives by enabling us to be reachable anywhere and anytime. All of our environments such as work and home converge through a single device and we can now receive private calls at work and professional calls during the weekend. Mobile technologies have transformed geographical distances and allow unplanned interruptions. While boundary theory suggests that individuals create, maintain and modify their boundaries in order to classify and simplify their environments, we focus here on how people use their devices and manage the boundaries that have been erased by mobile technologies. Based …
Convergence And Multidisciplinarity In Nanotechnology: Laboratories As Technological Hubs, Nicolas Battard
Convergence And Multidisciplinarity In Nanotechnology: Laboratories As Technological Hubs, Nicolas Battard
Articles
This article argues that research groups dedicated to nanoscience and nanotechnology are considered as technological hubs where scientists with multiple backgrounds converge in order to conduct research at the nanoscale (a billionth of a metre). Scientific production is therefore challenged as multiple ways of thinking, practices and knowledge participate in the creation of new outcomes. Through an exploratory and inductive study, I show that these technological hubs develop a specialisation based on internal competencies and stock of knowledge. The specialisation enables laboratories to position themselves as an expert among other laboratories as well as making them more visible in order …
