Towards Portable Nanophotonic Sensors

Nanophotonic Image Sensors

The increasing miniaturization and resolution of image sensors bring challenges to conventional optical elements such as spectral filters and polarizers, the properties of which are determined mainly by the materials used, including dye polymers. Recent developments in spectral filtering and optical manipulating techniques based on nanophotonics have opened up the possibility of an alternative ...

Chemical Sensors for Portable, Handheld Field Instruments

A review of three commonly used classes of chemical sensor technologies as applicable to implementation in portable, handheld field instruments is presented. Solid-state gas and chemical sensors have long been heralded as the solution to a wide variety of portable chemical sensing system applications. However, advances in optical sensing technology have reduced the size of supporting infrastruc...

Towards Collaborative Portable Web Spaces

As two recent trends in Web development, Widgets and mashups, are converging, we claim that there is a growing need to define a Widget Space configuration language to allow building flexible personal learning environments that could be independent of a runtime environment. By integrating the do-it-yourself dimension of a Web portal or Web mashup and the social dimension of the Web, we describe ...

Towards a Portable Lazy Functional Declarative Debugger

Declarative (or algorithmic) debugging is a promising technique for debugging lazy functional programs. This paper addresses two important reasons why it is not more widespread: the diiculty of writing a declarative debugger for a lazy functional language in the language itself and the eeciency of the debugger. Using the source language to implement the debugger is desirable for portability and...
