Signal Space Detection for DVD Optical Recording

A signal space detector (SSD) based on a single hyperplane is proposed which offers nearly the same performance as the fixed delay tree search with decision feedback (FDTS/DF) for the digital versatile disk (DVD) channel. The FDTS/DF detector with a reasonable decision delay performs almost as well as the optimal maximum likelihood sequence detector (MLSD) due to the EFMplus modulation code tha...

High Speed Data Recording for Defense Systems

The High Speed Data Recorder was designed to address the high speed, high channel count data acquisition needs of the Defense Threat Reduction Agency (DTRA). In the interest of national security, the United States Department of Defense pooled its resources, expertise and capabilities to create DTRA. The role of DTRA is to ensure that the United States remains capable of deterring, reducing and ...

A simple high-speed recording colorimeter system.

The rapid and continuous increase in microbiological assays requested of the routine clinical laboratory has created physical problems by the sheer number of tubes involved. One of the major difficulties is associated with the reading of large numbers of cultures with conventional instruments. In those assays where it is the rate of growth that is being measured, eg, Lactobacillus casei folate ...

Stereoscopic high−speed recording of bubble structures

Formations of acoustic cavitation bubbles in various resonator set−ups are recorded by high− speed stereoscopic means. The bubble distributions and motions are reconstructed in three dimensions. Such data is a key for better understanding of the mechanisms taking place in applications of intense ultrasound in liquids. Furthermore, the data serves for verification and improvement of particle mod...
