During 1996, the SLD collaboration completed construction and began operation of a new charge-coupled device (CCD) vertex detector (VXD3). Since then, its performance has been studied in detail and a new topological vertexing technique has been developed. In this paper, we discuss the design of VXD3, procedures for aligning it, and the tracking and vertexing improvements that have led to its wo...

A particle tracking technique at high particle concentration for the evaluation of flow fields beneath water waves is described. A 14 cm thick light sheet parallel to the main wave propagation direction was used to illuminate small polystyrol seeding particles. The depth of the light sheet was chosen such that the particles stay long enough in the illuminated area to enable tracking. An area of...

Discrimination data analysis has been investigated for the last fifty years in a large body of social, legal, and economic studies. Recently, discrimination discovery and prevention has become a blooming research topic in the knowledge discovery community. This chapter provides a multi-disciplinary annotated bibliography of the literature on discrimination data analysis, with the intended objec...

The charge transfer between hemispheres is investigated in the framework of a model with neutral and isotropic clusters. Without specifying the production mechanism of the clusters, the charge-transfer distribution can be uniquely determined by inclusive spectra. Minor discrepancies observed in the comparison with experimental data are attributed to the influence of the charges of the leading p...

User authentication is widely used in many Internet services and is also used by automatic teller machines (ATMs). Recently, there has been an increase in the ATM password thefts using small charge-coupled device cameras. This study discusses a user authentication method in which graphical passwords, instead of alphanumeric ones as, are used to mitigate observation attacks. Several techniques f...

The EXPLORE Project is a series of searches for transiting extra-solar planets using large-format mosaic CCD cameras on 4-m class telescopes. Radial velocity follow-up is done on transiting planet candidates with 8–10m class telescopes. We present a summary of transit candidates from the EXPLORE Project for which we have radial velocity data. 1 2 Mallén-Ornelas et al.

The synthesis of optimal narrow beam low sidelobe linear array is addressed. Only the length of the array is constrained. The number, the positions and the weightings of the elements are left free. It is proven, that the optimal design is always an array with a small number of elements. One first demonstrates that among equally spaced linear arrays of given length, the sparsest Dolph-Chebyshev ...

A PLL circuit includes phase detector for detecting phase error between an input and output signal of the PLL circuit and outputting pump up and pump down signal. A charge pump generates a charge pump signal in response to pump up and pump down signals. A loop filter filters charge pump signal to generate a filtered signal. A boost-up device coupled to loop filter output terminal charges a loop...
