The Accident and the Brokenness of History: Updated November 2015

An article to be presented at the seminar “Breakdown and other Technological Phenomena”– directed by Professor Don Ihde to be held during the fall term of 2010 at the Techno-science Research Group; Department of Philosophy, Stony Brook University Aristotle understood the word “accident” as an attribute of a class or a thing that is not essential. The word comes from Latin accidentum meaning “some

Localization of an RF source inside the Human body for Wireless Capsule Endoscopy

This paper presents a method based on the phase dierence of arrival and the non-linear least square estimation to lo- calize a radio-frequency (RF) source, e.g a wireless capsule endoscope, inside the human body. The phase dierence of arrival at multiple frequencies of a signal is used to estimate the distance of the source to a receiver. The linear least square estimation is used to estimate the

The role of institutional innovations in the transition to low-carbon futures

Deep cuts in carbon emissions to avoid dangerous climatic change will require fundamental transformations of the energy and transport systems. This is an enormous challenge for society and the political system. In order to tackle this challenge, we argue that it will be necessary to develop new institutions and institutional practices that address and give priority to long-term climate policy obje

A new finite element formulation of shock-induced hull cavitation

A new formulation for non-linear, elastic wave propagation, based on the pressure and density, is introduced. The formulation accounts for a non-linear relation between speed of sound and density. The pressure and density are interpolated by identical shape functions between the nodes. The equation of state is introduced in the discretized system, hence the non-linearity is enforced point-wise. Th
