Understanding the regional relationships between climate change and crop production will benefit strategic decisions for future agricultural adaptation in China. In this study, the combined effects of climatic factors on spring wheat phenophase and grain yield over the past three decades in Inner Mongolia, China, were explored based on the daily climate variables from 1981-2014 and detailed obs...

In this paper, the influence of heat treatment on PH17-7 stainless steel spring was evaluated. Precipitation hardening phenomenon of  PH 17-7 steel was evaluated in three stages. First, the spring constant changes with time and temperature was evaluated. Second, the spring constant changes with respect to its original length at constant temperature and time with blocking (spring length aft...

Every spring I get depressed. Last month I had the stunning realization that graduate student recruitment is a major cause of my spring depression. Each year, as the days lengthen, graduate programs engage in their ritualistic seduction of prospective students. In the past 15 years, US institutions, including the most elite and respected, have evolved mating displays worthy of birds and fish. T...

According to Sacks, it was Friedberg’s construction of a maximal recursively enumerable (r.e.) set that sparked interest in the distributive lattice of r.e. sets, modulo finite sets, under inclusion. Among the major results are the Lachlan’s characterization of the principal filters of hh-simple sets and Soare’s proof that the maximal sets form an orbit. We study the modular lattice L* of r.e. ...

Problem 1. As mentioned in class, the convex hull is a somewhat non-robust shape descriptor, since if there are any distant outlying points, they will tend to dominate the shape of the hull. A more robust method is based on the following iterative approach. Given a planar point set P in general position (see Fig. 1(a)), let H1 be the convex hull of P . Remove the vertices of H1 from P and compu...

China has recently experienced an increased demand for Western-style marketing and business practices due in part to a burgeoning economy and recent entry into the WTO. Market-based education has diffused rapidly across China as Chinese universities have started to imitate their Western counterparts and have entered into joint venture agreements with them. First, increased demand for Western-st...
