The Affymetrix GeneChip Scanner 3000 design lays the foundation for continued evolution of the GeneChip platform as an integrated genetic analysis system, supporting continued feature size reduction for higher resolution and greater information content of microarray-based products. The Affymetrix GeneChip Scanner 3000 will seamlessly incorporate future developments as GeneChip technology contin...

Proactive Vulnerability Assessments with Nessus The goal of this paper is to illustrate the benefits of deploying Nessus as a low-cost vulnerability scanner as a supplement to an existing security model. I'll discuss vulnerability scanning in general, what Nessus is all about, how to begin scanning your network, and finally why a vulnerability scanner is an essential component of an effective s...

SUMMARY Terrestrial laser scanners are widely used for metric applications of 3D modelling of buildings, bridges, tunnels and other structures. In common with any measurement system, the calibration of the laser scanner is of paramount importance to achieve the maximum possible accuracy. Even if a calibration certificate of the scanner is provided by the vendor, the scanner should be checked fr...

BACKGROUND AND PURPOSE Open MR imaging scanners are designed for imaging of specific patient groups that cannot be routinely scanned with conventional MR imaging scanners (eg, patients with obesity and claustrophobia). This study aims to determine whether BOLD sensitivity on an open 1T scanner is adequate for fMRI for diagnostic and research purposes by directly comparing fMRI results with a st...

We have developed a novel scanner for breast cancer detection, integrating both thermoacoustic and photoacoustic techniques to achieve dual contrast (microwave and light absorption) imaging. This scanner is nonionizing, low cost, and can potentially provide high-resolution, dual modality three-dimensional images of the breast. The scanner uses front instead of side breast compression and dry in...

The synthesis of controller algorithm for reversible electromechanical scanner of the telescope scanning axis is discussed. Digital control system is built without intermediate stage of synthesis of analog control law. The modified procedure for the synthesis of discrete optimal control law is introduced. Elasticity influence on static and dynamic characteristics of electromechanical scanner of...

A method based on extracted trunks is proposed for automatic determination of corresponding trees between a georeferenced pair of terrestrial images and airborne laser scanner data in a wooded area. Trunks in the terrestrial images are obtained by region growing segmentation between left and right edges of trunks detected within a region of interest. Trunks in a digital tree height model genera...

2D laser scanners have been widely used for accomplishing a number of challenging AI and robotics tasks such as mapping of large environments and localization in highly dynamic environments. However, using only one 2D laser scanner could be insufficient and less reliable for accomplishing tasks in 3D environments. The problem could be solved using multiple 2D laser scanners or a 3D laser scanne...

Payment and checkout at retail stores is increasingly being replaced by automated systems. One recent technological invention in this area is mobile self-scanning in which customers carry a mobile scanner while shopping. Mobile self-scanners give real-time feedback on spending. The device increases price saliency and enables customers to keep track of the total amount spent. Using a field exper...

Terrestrial laser scanner is a kind of fast, high‐precision data acquisition device, which had been more and more applied to the research areas of forest inventory. In this study, a kind of automated low‐cost terrestrial laser scanner was designed and implemented based on a two‐dimensional laser radar sensor SICK LMS‐511 and a stepper motor. The new scanner was named as BEE, which can scan the ...
