To recover wasted energy in the slew braking of hydraulic excavators, a slew-energy-saving system based on an accumulator is proposed. Mathematical models of the main system components are developed, by which the energy-saving system simulation is constructed using AMESim. A rule-based energy management control strategy is also proposed. The influence of system parameters on the fuel economy and control performance of the system is analyzed through several simulation tests. results demonstrate that the energy-saving system can raise the energy recovery ratio to 42% while maintaining great control performance of the entire machine. Finally, the prototype test verifies the effectiveness of the system and the simulation model.

In this paper, we deal with gaze behavior while walking a street and make comparison among Japanese residents, Japanese visitors, and Non-Japanese visitors. The authors carried out an experiment in which the participants wore eye tracker and walked along a shopping mall. The visual objects were classified into 9 categories and frequency of the categories and the frequency of transition among the categories were counted. The statistical analysis revealed the feature of the gaze behavior of the three groups.

Ltd. Guangming New District Shenzhen China

reflective light from a LCd panel without polarizers is analyzed and simulated. The influence of ITO, PI,BM and Metal are analyzed separately. An interlayer is designed and fabricated to alleviate reflectance at interface between glass substrate and the functional layers. As a result, the total reflectivity of a color Filter on Array LCd with the special polarizers is decreased from 1.5% to 0.8% or even lower for 4K UHd products.

Improved algorithms and coupled neutron-photon transport for auto-importance sampling method

Chinese Physics C 2017年第1期41卷 100-109页

The Auto-Importance Sampling（AIS） method is a Monte Carlo variance reduction technique proposed for deep penetration problems, which can significantly improve computational efficiency without pre-calculations for importance distribution. However, the AIS method is only validated with several simple examples, and cannot be used for coupled neutron-photon transport. This paper presents improved algorithms for the AIS method, including particle transport, fictitious particle creation and adjustment, fictitious surface geometry, random number allocation and calculation of the estimated relative error. These improvements allow the AIS method to be applied to complicated deep penetration problems with complex geometry and multiple materials. A completely coupled Neutron-Photon Auto-Importance Sampling（CNP-AIS） method is proposed to solve the deep penetration problems of coupled neutron-photon transport using the improved algorithms. The NUrEG/Cr-6115 PWr benchmark was calculated by using the methods of CNP-AIS, geometry splitting with russian roulette and analog Monte Carlo, respectively. The calculation results of CNP-AIS are in good agreement with those of geometry splitting with russian roulette and the benchmark solutions. The computational efficiency of CNP-AIS for both neutron and photon is much better than that of geometry splitting with russian roulette in most cases, and increased by several orders of magnitude compared with that of the analog Monte Carlo.

Journal of Physics: conference Series 2019年第2期1176卷

Non-intrusive Load Monitoring(NILM) is designed to determine the type of electrical appliance after decomposing the total power into each appliance in order to analyze how much electricity was consumed. In the traditional pattern recognition, relying on artificial extraction features, there is a large amount of unreliability, and then the use of convolutional neural networks to automatically extract features, but in the traditional CNN structure, when the network level is deepened, training error and test error will increase. Therefore, this paper proposes a network structure with residual unit added to the traditional convolutional neural network, in order to reduce the probability of gradient explosion. The dataset of the paper is the data collected from 22 different electrical appliances, and its current and voltage trajectory map is used to identify the accuracy rate of 97.9%.

Hydraulic excavators, especially medium and large excavators, waste a lot of energy during the frequent lifting-lowering process of its boom. recovery and regeneration the wasted energy is an important means to achieve energy saving and emission reduction of excavators. In this paper, a potential energy recovery and regeneration system based on a multi-cylinder structure working device is invented. Firstly, the theoretical analysis of the system, and the modeling and simulation research are carried out. results show that under the same boom-single-action conditions, the energy-saving efficiency of the excavator equipped with energy recovery system can reach 33%, it has important reference significance for evaluating the energy efficiency of the new system.
