In this paper, the lane reduction bottleneck is investigated using the optimal velocity model, in which two kinds of vehicles (fast and slow) are introduced. The asymmetric lane changing rules in the slowdown section and the lane squeezing behaviors at the bottleneck are taken into account....

In response to bottlenecks and dilemmas faced by institutions for agricultural and forestry practical training base construction, and based on Agriculture practical training base of Langfang Polytechnic Institute, this article illustrates the effective exploration and practice of the mode and...

In this paper, we propose a second order interior point algorithm for symmetric cone programming using a wide neighborhood of the central path. The convergence is shown for commutative class of search directions. The complexity bound is $${O(r^{3/2}\,\log\epsilon^{-1})}$$ for the NT methods, and...

Recent global initiatives on debt relief and development assistance call for increasing aid for trade to the poorest countries. We apply a multi-country computable general equilibrium model to measure the effectiveness of alternative aid for trade categories. Our findings show that aid for trade...

This paper tests the random walk hypothesis and weak form market efficiency in the VIX futures market using a variety of tests. A unit root in the aggregated market price series suggests that the VIX futures market is efficient. For the individual VIX futures price series, 51 of 54 futures...

This paper firstly introduces research achievements in change of rural society in China after reform and opening-up. Researches are conducted mainly in household contract responsibility system and the relation between township government and village administration. From the perspective of...

China faced the greatest challenge in balancing its economic growth, energy and resource security as well as environmental pollution. The energy-intensive industries, which used to be the major force driving China׳s economic growth, had seriously exhausted the countries׳ natural resources and...

The hydrogen storage performance of MgH2–10 wt.% TiC composite was investigated. The additive TiC nanoparticle led to a pronounced improvement in the de/hydrogenation kinetics of MgH2. The composite could dehydrogenate 6.3 wt.% at 573 K while the milled MgH2 only released 4.9 wt.% of...

In this paper, flash evaporation and thermal vapor compression are used to reduce heat consumption of CO2 capture processes and two improved capture systems are proposed. One is the flash evaporator (FE) and thermal vapor compressor (TVC)-aided system, the other is the heated flash evaporator...

This paper compared the effects of hydrogen and hydrogen–oxygen blends (hydroxygen) additions on the performance of a gasoline engine at 1400 rpm and a manifolds absolute pressure of 61.5 kPa. The tests were carried out on a 1.6 L gasoline engine equipped with a hydrogen and oxygen...
