Pay no attention to the alternatives behind the curtain: demand forecasting with missing data

Jeffrey Newman

Discrete choice modeling advances abound for scenarios where we can collect data about the behaviors of individuals, and observe their ultimate choice from among the range of possible alternatives. However, particularly in competitive private sector enterp ...

The Snakuscule

Michaël Unser, Philippe Thévenaz

Traditional snakes, or active contours, are planar parametric curves. Their parameters are determined by optimizing the weighted sum of three energy terms: one depending on the data (typically on the integral of its gradient under the curve, or on its inte ...

Probabilistic Tagging of Unstructured Genealogical Records

Michael Perrow

In this paper we present a method of parsing unstructured textual records briefly describing a person and their direct relatives. The string `Stephanus, brother of Johannes Magnin, from Saillon' is a typical example of a record. We wish to annotate every t ...

CO2 exchange between air and water in an Arctic Alaskan and midlatitude Swiss lake: Importance of convective mixing

Alfred Johny Wüest

[1] CO2 exchange between lake water and the atmosphere was investigated at Toolik Lake (Alaska) and Soppensee (Switzerland) employing the eddy covariance (EC) method. The results obtained from three field campaigns at the two sites indicate the importance ...

Evidence for two coupled subsystems in the superconducting state of La2-xSrxCuO4

Davor Pavuna, Mike Abrecht

We used a pump-probe technique to measure the transient change of optical reflectivity of both La2-xSrxCuO4, of various dopings, and slightly underdoped YBa2Cu3O7-x and NdBa2Cu3O7-x thin films. For the La2-xSrxCuO4 films, our data demonstrate the coexisten ...

Read/write holographic memory versus silicon storage

Demetri Psaltis, Wei Liu

This paper compares the read/write holographic memory with silicon storage on issues of cost, density, size and speed. With a photorefractive crystal on top of a silicon interface, the holographic memory is of cost efficiency, volume compactness and fast d ...
