Reliable and durable asphalt surfacing systems still remain to be desired for the long-spanned orthotropic steel bridges as the nationally and internationally reports on distresses in deck pavement. Based on ten-year research works, this paper has presented a brief review and discussion of the Chinese practices and experiences of deck pavement on long-spanned steel bridges, including issues of ...

Consider an undirected graph G. A random walk of length l starting at the vertex u is a sequence of vertices u = v0, v1, v2, · · · , vl, where each vi is chosen to be a random neighbor of vi−1 for all i > 0. One considers the distribution of vi for i ≤ l. Intuitively, a random walk can be thought of as choosing a globally random vertex on a graph using only local choices. This is something that...

This report gives account of the seminar on Logic Databases and The Meaning of Change, held at the marvelous conference and research center of Dagstuhl, in the last week of September 1996. The seminar attracted a total of 36 invited researchers in the field, from 14 countries. Each of the participants contributed to the seminar by giving talks, demonstrations and/or participating in lively disc...

Workers in the commercial fishing industry have the highest occupational fatality rate in the United States, nearly 35 times higher in 2011 than the rate for all U.S. workers. During 2000-2009, a total of 504 fishermen were killed in the U.S. fishing industry, most commonly by drowning as a result of vessels sinking (51%) and falls overboard (30%). Another 10% of fatalities (51 deaths) were cau...

We installed two global navigation satellite system (GNSS) antennas on a research vessel, the RYOFU MARU of the Japan Meteorological Agency, and conducted experimental observations to assess the GNSS-derived precipitable water vapor (PWV) from October 19, 2016, to August 6, 2017. One antenna was set on the mast (MAST), while another antenna was set on the upper deck (DECK). The GNSS analysis wa...
