The Uniqueness of Groups of Lyons Type

We give the first computer free proof of the uniqueness of groups of type Ly. We also show that certain simpicial complexes associated to the Lyons group Ly have the same homotopy type as the Quillen complex for Ly at the prime 3; we show this complex is simply connected, and we calculate its homology. Finally we supply simplified proofs of some properties of groups of type Ly, such as the grou...

CJ 2000-Lyons (vol. 1)

The underlying thesis of this paper is that crime control policy is politically constructed. In developing our thesis and its implications, we depart from much of the conventional wisdom in three basic ways. First, in demonstrating the political derivations of crime control policy we reveal how, why, and to what extent criminological knowledge is marginalized in the policymaking process. Second...

Astronomical Telescopes at the Turn of the Century

The final years of the XXth Century and the initial years of the XXIst Century are witnessing a revolution in the construction of large telescopes. This has been possible thanks to the availability of both thin mirror technologies and large computing power. Astronomy is thus benefiting from this. Indeed the turn of the century has been rich with new discoveries, from the detections of extrasola...

Night sky at the Indian Astronomical Observatory during 2000 − 2008

This paper presents an analysis of the optical night sky brightness and extinction coefficient measurements in UBVRI at the Indian Astronomical Observatory (IAO), Hanle, during the period 2003−2008. They are obtained from an analysis of CCD images acquired at the 2 m Himalayan Chandra Telescope (HCT) at IAO. Night sky brightness was estimated using 210 HFOSC images obtained on 47 nights and cov...
