The City College of the City University of New York (known more commonly as the City College of New York) is a senior college of the City University of New York (CUNY), in New York City. It is also the oldest of the City University's twenty-three institutions of higher learning. City College's thirty-five acre Manhattan campus along Convent Avenue from 130th Street to 141st Street is on a hill overlooking Harlem; its neo-Gothic campus was mostly designed by George Browne Post, and many of its buildings are landmarks.

Atmospheric 14CO2 over the mid Pacific Ocean and at Point Barrow, Alaska, USA from 2002 to 2004 Xiaomei XU (xxu@uci.edu), Susan TRUMBORE, Henry AJIE, Stanley TYLER, and Jim RANDERSON Earth System Science Department, University of California, Irvine, CA 92697/USA Nir KRAKAUER Division of Geological and Planetary Sciences, MC 100-23, California Institute of Technology, Pasadena, CA 91125/USAUCI University of California, Irvine B23A-0948 14CO2 is a useful tracer for studying the carbon cycle, in terms of determining residence times and fluxes between different carbon reservoirs, and understanding the various underlying processes. Knowledge of the regional and global distribution of atmospheric 14CO2 is essential for many of these applications. We have recently begun measuring atmospheric 14C in the mid-Pacific and at stations in the U.S. to enhance our understanding of the patterns of atmospheric 14C distribution and its seasonal variation. INTRODUCTION SAMPLE COLLECTION AND MEASUREMENT CONCLUSIONS RESULTS AND DISCUSSION Atmospheric CO2 samples over the Pacific Ocean were collected in two shipboard transects. The first one is between Manzanillo, Mexico (16°N, 109°W) and Auckland, New Zealand (34°N, 177°W) from Sept. 23 to Oct. 4, 2002. The second transect is between Los Angeles, US (34°N, 118°W) and Auckland from July 28 to Aug. 10, 2003. Upon returning to the lab, CO2 is cryogenically purified on a vacuum line, sub sampled for d13C analysis, and then reduced to graphite using titanium hydride, zinc, and a cobalt catalyst [2]. The graphite is analyzed for 14C at the W.M. Keck AMS facility at UC Irvine. These air samples were also measured for C-trace gas abundance (CO, CH4 in addition to CO2, and their stable isotopes). We have also been monitoring 14CO2 from three fixed surface sites in the US: a coastal site at Point Barrow, Alaska (71°N,... |

SensorsCSC I6716 Spring 2004 3D Computer Vision and Video Computing http://www-cs.engr.ccny.cuny.edu/~zhu/VisionCourse-2004.html Part 1 Topic 2: Sensors Instructor: Zhigang Zhu This course is a basic introduction to parts of the field of computer vision. This version of the course covers topics in 'early' or 'low' level vision and parts of 'intermediate' level vision. It assumes no background in computer vision, a minimal background in Artificial Intelligence and only basic concepts in calculus, linear algebra, and probability theory. |
