Recent technological improvements and application opportunities have fueled increased interest in the development and deployment of underwater acoustic sensor networks. Deployment efforts have been impeded by the prohibitive monetary cost and high power consumption of existing acoustic hardware. Alternately, we propose underwater networks that rely on widely available speakers and microphones i...
We describes a framework in which to view the end-to-endindependently-verifiable (E2E) voting systems based on mixnets. We use the framework to invent new systems that combine front and back-ends from existing systems.
I t’s no secret that the world is shrinking. The “death of distance” has had a profound impact on invention, innovation, and business, as many before us have noted. Historically, engineers and scientists have worked within local clusters of collaboration that were generally isolated within firms (and even within divisions of firms). However, as inventors have become increasingly mobile, these f...
This paper analyses the solving process of two undergraduate students on a non-routine mathematical problem. By comparing these students’ work, it can be observed that their processes suggest different approaches in relation to the way a solution was sought. One student followed a process in which his principal activities were centred on discovering those key ideas that would allow him to tackl...
The old dictum says that if the Devil did not exist, the Church would have had to invent him. Similarly, if the regulator didn't exist, the airline industry would have had to invent him-and did in 1938. A current question is what would happen to the industry were it totally deregulated. One thesis is that there would be a rush by existing and new entrants to those routes thought to be profitabl...
Invention activities are Productive Failure activities in which students attempt to invent methods that capture deep properties of given data before being taught expert solutions. The current study evaluates the effect of scaffolding on the invention processes and outcomes, given that students are not expected to succeed in their inquiry and that all students receive subsequent instruction. Two...
We prove that the conformal group of a closed, simply connected, real analytic Lorentzian manifold is compact. DâAmbra proved in 1988 isometry such compact [Invent. Math. 92 (1988), pp. 555â565]. Our result implies Lichnerowicz Conjecture for manifolds with finite fundamental group.
Transformative research requires transdisciplinary collaboration, forcing researchers out of their disciplinary comfort zones. In projects, the role (social) scientists changes, and non-scientific actors become part projects. Transdisciplinary is particularly suited to not only generate scientific knowledge, but also invent real-world solutions innovative. This, however, does come without chall...
