To maximize the number of vehicles passing by the stop-line in a cycle and improve the operation efficiency of intersection in China, the settlement of left-turn lane waiting-zone is becoming prevailing. Based on conflicting-point method, the internal mechanism of left-turn flow after stopping line was analyzed through taking postposition left-turn lane waiting-zone intersection for instance. The relationship between the first left-turn vehicle and the last vehicle of previous phase passing the conflicting point was expounded. According to the time of successive arriving of two vehicle flows at conflicting-point, the reasonable layout for waiting area of left-turn vehicles was researched when the clearance index was less than O. The results suggest that the appropriate layout for waiting area of left-turning vehicles can improve the operation efficiency of intersections. 展开更多

The railway passenger seat inventory control problem in China was addressed. Chinese passenger railway operation features and seat inventory control practice were analyzed firstly. A dynamic demand forecasting method was introduced to forecast the coming demand in a ticket booking period. By clustering, passengers' historical ticket bookings were used to forecast the demand to come in a ticket booking period with least squares support vector machine. Three seat inventory control methods: non-nested booking limits, nested booking limits and bid-price control, were modeled under a single-fare class. Different seat inventory control methods were compared with the same demand based on ticket booking data of Train T15 from Beijing West to Guangzhou. The result shows that the dynamic non-nested booking limits control method performs the best, which gives railway operators evidence to adjust the remaining capacity in a ticket booking period. 展开更多

Based on the empirically analysis of the data from a nationwide survey in 2010 in China, the study found. (1) The overwhelming majority of rural migrant workers in China were not willing to convert their rural household registration (nongye hukou) to an urban or non-rural registration Orei nong hukou). If they were required to return the rural land contract rights as precondition, only lOper cent were willing to be urban citizens. (2) For the small proportion of migrant workers who were willing to convert their rural household registration to urban household registration, 'obtaining access to better education and more opportunities for the continuation of education for their children' is the major incentive. (3) The primary reason for retaining a rural hukou, on the other hand, is to keep their rural contract land. (4) Finally, there is no significant difference between the rural migrant workers who were born before 1980 and those after 1980, in term of the attitude toward converting rural hukou to urban hukou. The policy recommendations drew from the findings are as follows: 1) In order to promote the urbanization process, the government should choose the path of 'urbanization based on the long term residence in the towns and cities' instead of the path of "urbanization based on household registration '. 2) The rural migrant workers should be converted into urban citizens without being forced to give up their contact land. 3) The government should give equal weight in policy making to the migrant workers born before 1980 and those born after 1980. Therefore, the policy emphasis of deepening the urbanization of China should focus on the 'equalization of the resource allocation of the public services and social welfare" while the characteristics of the separation of the household registration system should not be strengthened any longer. 展开更多

Datong-Qinhuangdao line, as the first electrified double-track heavy-haul line dedicated to coal transport in China, extends from Datong in the west, and reaches Qinhuangdao in the east, opened to traffic in December, 1992, totaling 653 km with the designed annual traffic volume of 1×108 t. In order to meet the demands of national economic development, the transport capacity of the line must be enhanced greatly. Depending on independent innovation, MOR, for the first time in the world,realizes the integration between GSM-R and Locotrol, the integration between 800 MHz digital radio and Locotrol, and the integration between a single set of Locotrol and SS4 locomotive. Meanwhile, CR develops equipment portfolio for heavy-haul through combining 2 high power locomotives of HXD series (means harmony) with controllable EOT. Relying on integration and innovation, it succeeds in operating 20 kt-level combined heavy-haul train on Datong-Qinhuangdao line, which tripled the annual traffic volume of the line from 1×108 t in 2002 to 3×108 t in 2007. 展开更多

We give the brief review on the related definition of the geometric phase independent of specific physical system based on the displacement opreator and the sqeezed operator, then show how the displacement operator and the squeezed operator can induce the general geometric phase. By means of the displacement operator and the squeezed operator concerning the circuit cavity mode state along a closed path in the phase space, we discuss specifically how to implement a two-qubit geometric phase gate in circuit quantum electrodynamics with both single photon interaction and two-photon interaction between the superconducting qubits and the circuit cavity modes. The experimental feasibility is discussed in detail. 展开更多

There is a danger of power generation efficiency decreasing due to voltage increase when clustered residential PV systems are grid-interconnected to a single distribution line. As a countermeasure, installation of the reactive power control of an inverter at each residence has been considered. However, there are not many types of inverters that can operate reactive power control because there are insufficient effects on a low voltage distribution line with low penetration PV with reactive power control. Therefore, it is necessary to consider how to increase generation efficiency with a lower number of inverters. In this paper, four Japanese standard distribution line structures, for example of a residential area on "C1", where 2,160 residential PV systems are grid-interconnected, are selected. The optimal setting of reactive power control at each residence is computed on the distribution lines with a greedy method. 展开更多

Batteries transfer management is one important aspect in electric vehicle(EV)network's intelligent operation management system.Batteries transfer is a special and much more complex VRP(Vehicle Routing Problem) which takes the multiple constraints such as dynamic multi-depots,time windows,simultaneous pickups and deliveries,distance minimization,etc.into account.We call it VRPEVB(VRP with EV Batteries).This paper,based on the intelligent management model of EV's battery power,puts forward a battery transfer algorithm for the EV network which considers the traffic congestion that changes dynamically and uses improved Ant Colony Optimization.By setting a reasonable tabv range,special update rules of the pheromone and path list memory functions,the algorithm can have a better convergence,and its feasibility is proved by the experiment in an EV's demonstration operation system. 展开更多

Internal control is a hot topic at present academics and for practitioners to explore. Especially under the background of China' s rapid integration into the global economy, the rapid establishment and improvement of the context of the modem enterprise system, the issue is of utmost importance. The internal accounting control system is the core part of internal control, which determines the extent of establishing the entire sound internal control system, With the progress of the time, the rapid development and wide application of Internet technology has changed the survival environment and management philosophy for business. The development of network technology achieves the online office, mobile office and decentralized offices, etc. Accounting entity is no longer subject to space limitations of traditional methods, thus a large number of accounting information is transmitted tbaough the network communication lines, so that accounting activities can be extended to every node in the world, which achieves the purpose of remote processing. Under the network environment, sources of information are of diversity and multi-channel. A large number of accounting information transmitted from the network communication lines is likely to be illegally intercepted, stolen and tampered by molecules or people with ulterior motives. 展开更多
