Timing the Occurrence of Randomly Spaced Events using $V_{T}$ Shift in Disordered Semiconductors
This paper discusses the concept of using threshold voltage shift ($V_{T}$ shift) in disordered semiconductors based thin film transistors to measure the time of occurrence of randomly spaced events of…

Whatever: free choice and uncertainty
I show that these implications are a special case of free choice effects and arise as a result of the types of alternatives -ever free relatives are associated with and…

Cross-media linking and tagging support for learning groups
We present a pen-based and tangible interaction concept for the linking and tagging of documents in a mixed physical and digital environment.
-
Cyber security technology usability and management
This chapter reviews recent results on designing systems that are usable, useful, and secure, and describes general principles important in the management of secure systems.
-
Efficient waypoint tracking hybrid controllers for double integrators using classical time optimal control
We present two methods, one which will track general way point specs, and another which will track waypoints that lie on convex or concave trajectories.
-
Image objects and multi-scale features for annotation detection
This paper investigates several issues in the problem of detecting handwritten markings, or annotations, on printed documents.
-
The interplay of materials in printed electronics
Here some of the aspects related to the gate dielectrics are discussed and device applications of printed electronics are presented.

Spatially modulated emission for point-of-care flow cytometer
In this presentation we will describe and illustrate a fundamentally new design of the optical detection system that delivers high effective sensitivity (i.e., high signal-to-noise discrimination) without complex optics or…
-
Efficient broadcast in wireless ad hoc and sensor networks with a realistic physical layer
We present an analytical model to show that the transmission radii used for nodes can be used to establish a tradeoff between minimizing energy consumption and ensuring network coverage.

Structural Analysis of Zincocenes with Substituted Cyclopentadienyl Rings
New zincocenes with substituted cyclopentadienyl ligands have been prepared by the reaction of ZnCl2 with the appropriate Cp′-transfer reagent.

Inferring D Region Parameters Using Improved Incoherent Scatter Radar Techniques at Arecibo
With the increased sensitivity and bandwidth, Arecibo 430 MHz incoherent scatter radar was run on 23 July 2006 using two radar modes with a focus on measuring D region parameters.

Measured and Modeled Ionospheric Densities, Temperatures, and Winds During the International Polar Year
This paper examines the ability of ionospheric models to reproduce measured electron density, winds, and temperatures during the International Polar Year (IPY) in 2007.
