On the premise of ensuring that the driving state of the vehicle conforms to the driver's intention, it is of practical significance to study the energy-saving of the vehicle. Through the correlation analysis of acceleration / brake pedal signal with vehicle speed and acceleration under real working conditions, the strong correlation between driver input and vehicle speed appears in the range of 4-6 seconds. The mapping relationship between driver’s intention and driver's expected speed is constructed by extreme learning machine. Based on this, the model predictive control for hybrid electric vehicle is carried out. It is compared with the global optimal control strategy solved by dynamic programming and the instantaneous optimal control strategy under the same discrete precision. The results show that compared with the instantaneous optimal control strategy, model predictive control based on driver’s intention can save 9.92% of the energy consumption while meeting the driver’s intention (RMSE 0.9995m/s).","PeriodicalId":11324,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Sciences","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85240394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fully environmentally friendly automatic construction equipment, such as excavators, are perceived as vital for safe, productive, and resilient future construction sites. However, there is much uncertainty about the technologies which need to be adopted and developed in order to effectively achieve this end and provide the industry with strategic direction. This paper explores current academic thinking about technology roadmaps and technological innovations of excavation operations, in order to identify the components for automated excavation technology roadmaps. Literature in well-established databases are identified using robust search strategies. Text mining, a quantitative approach, was used to analyse and organise findings. Three main technology innovation categories were identified: 1) real time positioning systems; 2) technologies to detect over ground objects, 3) technologies to detect below underground objects. In addition, multi-sensory data fusion methods are identified as an essential and vital requirement for construction automation.","PeriodicalId":11324,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Sciences","volume":"509 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86240853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Few researches exist involving the integration of the two monitoring methods. Following this study, a distributed numerical model for frozen soil processes based on coupled water-heat transferring theory in association with the previously obtained remotely sensed frozen soil datasets will be developed. Parameters characterized the frozen soil status, such as distributions of frozen soils in different types, soil ice content in different times and so on, could be simulated with the developed model. The numerical model systematically integrates the information of surface soil F/T states and considers its impact on the processes of evapotranspiration, infiltration and runoff generation. Several hydrological processes were integrated in the model. Finally, the remote sensing monitoring and numerical simulation coupling method was validated by the in-situ observations over a remote area near the town of Naqu on the East-Central Tibetan Plateau. The results shown that the overall accuracy of the discrimination algorithm based on passive microwave remote sensing was more than 95%. Under the correction of remote sensing monitoring information of frozen soil in the process of numerical simulation, the efficiency of the model and the accuracy of simulation results have been significantly improved.","PeriodicalId":11324,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Sciences","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81791646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking 2000–2014 as the research period, this paper studies the indirect CO emissions of household consumption in China by using the MRIO model and uses SDA to analyze the driving factors of indirect CO emissions of household consumption in China. The results show that: (1) During the study period, the indirect CO emissions caused by household consumption in China showed an increasing trend, with the total household amount increasing by 1.9 times, and the per capita CO emissions increasing by 1.76 times. (2) The CO emissions from household consumption in China are concentrated mainly in Commercial and Public Services (CPS), Electricity, Gas, Steam and Air Conditioning Supply (EGSA), and Manufacture of Food and Tobacco (MFT), which accounted for 26.63%, 17.69% and 13.52%, respectively, of the total emissions in 2014. (3) China has been in the position of net outflow of indirect CO emissions from household consumption. (4) The growth of per capita household consumption is the main factor promoting the growth of indirect CO emissions from household consumption in China, and the reduction of carbon intensity in various countries is the main factor in restraining the indirect CO emissions caused by household consumption in China. This study shows that indirect CO emissions from household consumption in China are likely to rise, and the government should not only improve the level of household consumption continuously but also actively adjust the industrial structure and optimize the consumption structure to alleviate CO2 emissions effectively.","PeriodicalId":11324,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Sciences","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88675188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
