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

The problem of adaptive control is considered from a perspective of l2-gain. It has recently been shown that without an a priori bound on the system parameters, there exists no single dynamic feedback law that achieves bounded gain from disturbances to state for all first order linear systems. In this paper, a converse statement is proved for a standard adaptive scheme where the parameter estimate

This chapter introduces the basics of eye anatomy, eye movements and vision. It will explain the concepts behind human vision sufficiently for the reader to understand later chapters in the book on human perception and attention, and their relationship to (and potential measurement with) eye movements. We will first describe the path of light from the environment through the structures of the eye

This paper is concerned with two approaches to designing spaces for knowledge work. The central concern of the first approach is with the use of fictional descriptions of the workplace, in order to stimulate creative thought about new workspaces. The second approach draws on the emerging potential of three dimensional virtual reality as a tool to develop shared visions and to stimulate creativity.

LTRs of endogenous retroviruses are known to affect expression of several human genes, typically as a relatively minor alternative promoter. Here, we report that an endogenous retrovirus LTR acts as one of at least two alternative promoters for the human beta1,3-galactosyltransferase 5 gene, involved in type 1 Lewis antigen synthesis, and show that the LTR promoter is most active in the gastrointe

Thermally driven rotational and translational diffusion of proteins and other biomolecules is governed by frictional coupling to their solvent environment. Prediction of this coupling from biomolecular structures is a longstanding biophysical problem, which cannot be solved without knowledge of water dynamics in an interfacial region comparable to the dry protein in volume. Efficient algorithms ha

This is a study in the field of history of ideas which places the hunger riots of 1917 in Gothenburg in the context of the struggle for women’s suffrage. A gender perspective on contemporary media shows that the presentation of women’s participation differed between the newspapers according to its political ideology. An analysis of the concepts of hunger and riots has enabled a comparison between
