This paper describes a trial detection system to monitor the behavior of patients walking along the corridor of a group home for dementia patients. Generally, we do not install video cameras, in order to protect the privacy of the residents. We have developed a simple linear array sensor to detect the behavior of a person walking along the corridor. We have deployed these linear array sensors a...

A micron-precision optical alignment system (OASys) for the PHENIX muon tracking chambers is developed. To ensure the required mass resolution of vector meson detection, the relative alignment between three tracking station chambers must be monitored with a precision of 25μm. The OASys is a straightness monitoring system comprised of a light source, lens and CCD camera, used for determining the...

In this paper, we study containment properties of graphs in relation with the Cartesian product operation. These results can be used to derive embedding results for interconnection networks for parallel architectures. First, we show that the isomorphism of two Cartesian powers Gr and Hr implies the isomorphism of G and H, while Gr ⊆ Hr does not implyG ⊆ H , even for the special cases whenG andH...

Short fruit cucumber was chosen as object. Different nutrition conditions were applied to cultivate plants.CCD camera with special filters was used to gather images. Correlation analysis results shows that four indexes, CNDVI, GNDVI, NDGI and NDVI, had much higher correlation with nitrogen content of cucumber leaves. LS-SVM algorithm was proposed to construct models between vegetation indexes a...

A method for calibrating single scanline CCD cameras is described in this paper. We show that the more classical 2-D camera calibration techniques are necessary but not suflicient for solving for the 1-D camera calibration problem. We propose a model for single scanline cameras, and we provide a two-step procedure for estimating its parameters. We also show how the extrinsic camera parameters c...

A CCD imaging system has been developed for precision laser beam pointing. The systcm contains a high frame rate CCD camera operated in windowing mode under command of an ernbeddcd processor. A ltiser pointing and tracking update rate of 2 KIIz has been achieved. Subject terms: CCD cameras, laser pointing, laser communications.

We present broadband V,I CCD photome-try for ∼ 1700 stars towards the Galactic globular cluster Palomar 12, covering a field of 10. ′ 7 × 10. ′ 7. From these data, a color-magnitude diagram from the red giant branch tip to ∼ 2 mag below the cluster's turn-off is obtained. From a comparison with the color magnitude diagrams of 47 Tuc and M5, and using different theoretical models, we confirm tha...

This paper proposes a novel architecture for multisensor data fusion in the context of Ambient Intelligence (AmI). The proposed system integrates an heterogeneous network of sensors with CCD cameras and computational units working together in a LAN. Activities of humans interacting in the monitored area are detected and classified by combining sensors data output with a neural method.

In this paper, the Weiss-Weinstein bound is analyzed in the context of sources localization with a planar array of sensors. Both conditional and unconditional source signal models are studied. First, some results are given in the multiple sources context without specifying the structure of the steering matrix and of the noise covariance matrix. Moreover, the case of an uniform or Gaussian prior...

By means of VI CCD photometry we identify a new globular cluster in the Galaxy: ESO 280−SC06. The images and Colour Magnitude Diagrams indicate that we are dealing with a sparsely populated globular cluster, showing a compact core. The cluster is located in Ara, projected at only 12.6 o from the plane, and appears to be metal poor ([Fe/H] ≈ −1.8). We derive a reddening E(B−V) = 0.07 and a dista...
