Spectral bandwidths for the detection of color

The spectral properties of human color detection mechanisms were measured using a noise masking technique that minimizes the possibility of off-axis looking and artifactually narrow estimates of bandwidth. Observers were induced to use a single detection mechanism throughout a spectral bandwidth measurement by using sectored noise to mask a time-varying signal of fixed chromatic properties. Sec...

UV absorbance measurements of DNA in microplates.

UV absorbance measurements in microplates became possible only five years ago when Molecular Devices (Sunnyvale, CA, USA) introduced the SPECTRAmax 250, the first UV-Visible microplate spectrophotometer. Microplates have since become very popular for making UV measurements of DNA, RNA and protein concentrations because of their higher throughput compared to traditional cuvettes. Despite their ...

Effective Bandwidths at Multi-Class Queues

Consider a queue which serves traffic from a number of distinct sources and which is required to deliver a performance guarantee, expressed in terms of the mean delay or the probability the delay exceeds a threshold. For various simple models we show that an effective bandwidth can be associated with each source, and that the queue can deliver its performance guarantee by limiting the sources s...

Analysis of Light-Induced Absorbance Changes in the Near-Infrared Spectral Region I. Characterization of Various Components in Isolated Chloroplasts

Light-induced absorbance changes in the near-infrared (NIR) spectral region (700 -950 nm) are analyzed in isolated spinach chloroplasts using pulsed light-emitting diodes as modulated measuring light sources. With chloroplasts under coupled conditions the light-induced signal is dominated by a relatively slow scattering change displaying a flat difference spectrum. More specific changes can be ...
