<title>Abstract</title> Background. Our study aimed to evaluate vaccine effectiveness (VE) of a live oral pentavalent rotavirus (RotaTeq, RV5) among < 5-year-old children in three provinces China via propensity score matched test negative design case-control study. Methods. We used electronic health records and person-matched immunization information system data obtain on acute gastroenteritis (AGE) cases Guangdong, Beijing, Hubei evaluated for AGE emergency department settings tested...
Intelligent connected vehicle is the key to competition in second half of automotive industry reform As a link before technical iteration and commercial application, test, evaluation, demonstration application intelligent vehicles have been highly valued by state local governments This paper focuses on summarizing construction test area zone China, analyzing progress advanced achievements main pilot zone, then achievements, studying judging problems existing development pushing forward...
The development of new energy vehicles is the inevitable path for China's automotive industry to transition from being a large player powerful one. This article focuses on analyzing current status industry, particularly in realm vehicles. It examines domestic market situation and export competition landscape vehicles, further evaluating vehicle chain, technological situation, enterprise landscape, regional distribution pattern core components. Finally, based problems existing it puts forward...
At present, the new energy used car industry urgently needs a standard method that can accurately calculate residual value of cars. This paper first determines product calculation dimension based on data from Guazi Website; Secondly, we need to perform preprocessing such as searching and processing for outliers missing values in source; Once again, feature engineering deleting, merging, reorganizing dimensions; Finally, XGBOOST model was The results showed when sample size popular models...
This paper proposes a study based on the importance of automobile industry chain input‐output model (IOM) to verify in national economy. The available data shows interdependence among various industrial sectors and chain. same is reflected table. input taken from table (IOTB) A mathematical was developed that equilibrium relationship indicating direct indirect technical as well economic links amongst different sectors. static IOM selected. herein reflects correlations during period. applied...
The oscillation phenomena in the Modular Multilevel Converter (MMC) based HVDC system has caused severe damage to related devices and grids. fundamental causes of oscillations can be very sophisticated depending on configuration control operation system. Therefore, an impedance model MMC was proposed while considering dynamic characteristic each loop overall signal delays scheme. results have shown that, current inner loop, active power great impacts characteristics converter. loops delay...
To build a strong automotive company, it is essential to monitor and calculate each indicator of brand car the score power in real time. In this paper, firstly, subjective objective data research (subjective data) sales car(objective year month are combined form multi-source heterogeneous data. And then pre-processing performed on basis data, includes removal attribute features without contribution, detection filling outliers missing values, etc. Secondly, Introduces advantages Flink...
Behind the fierce market competition, intellectual property rights of new energy vehicles play a vital role. Intellectual is main means for enterprises to protect R&D achievements, and it also legal guarantee protecting leading position. China's automobile industrialization can never be completely realized in short time. We must rely on independent research development down-to-earth, based technological status world's industry, avoid fatal mistakes future industry caused by risks. Based big...
When manufacturing automobiles, a lot of automobile spare parts are needed, which gradually leads to the production parts, is not manufactured by vehicle manufacturers, but completed purchasing thus forming supply chain. Therefore, it particularly important control risk chain, related success or failure whole Based on DM(data mining) technology, this paper studies chain industry, and gives an early warning prevention risk. Through research analysis, can be found that whether interval...
In order to ensure the normal operation of OBD (On Board Diagnostics) system, manufacturers are required conduct self-examination and supervision which is performance evaluation production vehicles. Multi-objective GA (Genetic Algorithm) simulates process biological evolution, dealing with a population, can generate large number non-inferior solutions in one optimization process, so it search approximate Pareto optimal solution set multi-objective problems. this paper, fault diagnosis model...
A large quantity of Electric Vehicle (EV) charging station loads connected to the power grid will aggravate peak-valley difference and reduce stability system economic benefits operation. The connection EV also inject a harmonics into grid, further aggravating risk supply equipment failure. can be regarded as distributed energy storage devices. Under special circumstances, feed back electric through conversion devices participate in frequency modulation grid. In order idle rate stations...
The emergence of the new economic model, continuous development and application high technology, its penetration into consumption field have led to many changes in consumer behavior. Mastering changing trend behavior plays an important role developing production, invigorating circulation guiding consumption. automobile distribution industry has accumulated a lot data, including information, customer information so on. These data are references for market operation dealers. Based on...
