Conceptions of 'information poverty' in LIS: an analysis of discourses
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
In-situ phase studies of the Zr-H system
Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. However, zirconium has strong affinity for hydrogen, which may lead to hydrogen concentration build-up over time during a corrosion reaction when exposed to water. Hydrogen stays in solution at higher temperature but precipitates as zirconium

A Pulse Technique for Control of Fed-batch Fermentations
A strategy for control of substrate feed rate in fed-batch fermentations is presented. The main idea is to make pulses in the feed rate and to evaluate the response in the dissolved oxygen signal. This gives an indirect measurement of the substrate demand that is used for feedback control of the feed rate. Experimental data is used to develop a model of a fermentation process. The model is used to
Growth of Semiconductor Nanowires for Solar Cell Applications
Nanowires have the ability to absorb light much more efficient than conventional thin film layers. This makes them candidates for the development of new types of solar cells that have higher efficiency and lower material usage than current technologies. In this thesis fabrication of nanowires with techniques suitable for large area applications are investigated. The nanowires are grown by either M

Utilizing Multipath Clusters in Cognitive Radio Systems
In this paper, we introduce a new technique that allows the coexistence of secondary users (SUs) with a primary user (PU), in the same frequency and time. The proposed technique (i.e., the cluster-based spatial opportunistic spectrum sharing (CB-SOSS) technique) exploits the spatial degrees of freedom resulting from the use of multiple antennas at both the secondary base station (SBS) and SUs; als

Mixed Integer Programming Model of MCCA-aware Acknowledging in Wireless Mesh Networks
The paper investigates advantages of using an MCCA-aware acknowledging system in IEEE 802.11s Wireless Mesh Networks (WMN). The MCCA (MCF controlled channel access) protocol allows for reserving time slots for a point-topoint transmission over a wireless link. The protocol assures that the transmission will not be hindered by any other 802.11 device that uses MCCA, by preventing all neighbors of b
