Energy recovery technology is a crucial part of them. The basic principle of how electric vehicles work is to convert chemical energy into electrical energy, and then convert electronic energy into kinetic energy. Actually, the ability of deceleration is necessary for electric vehicle. However, large amount of energy may lose due to this period. So, people developed energy in order to recover this energy.This study contain the introduction of two different types of energy recovery system, electronic energy recovery system and mechanical energy recovery system. Including two major advancements in this field in recent decades which contribute a lot in electronic recovery system. In addition, I introduced some latest research on mechanical energy recovery system which utilized hydro-mechanical technology. Most of my analysis are based on ECE (European standard operating conditions) . Worth noticing that more areas for expansion of this technology are also mentioned in my essay such as rotorcrafts and motor-driven tanks which are the latest products.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"78 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140452220","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}

This dissertation explores the innovative application of Neural Radiance Fields (NeRF) technology in transcending the boundaries of physical museums and transporting their treasures into the metaverse. While classical computer vision has seen substantial progress, a developing intersection exists between NeRF and cultural heritage preservation. This study bridges this gap by introducing an approach that amalgamates NeRF techniques with the rich cultural wealth of museums.The conventional museum experience is extended into the metaverse through a novel methodology that leverages NeRF’s capabilities. The core objective is to enable individuals to explore digitized museum artifacts with unparalleled realism. NeRF technology captures intricate visual details and enables immersive interactions by rendering scenes with volumetric precision, transforming how cultural artifacts are experienced and understood.This dissertation delves into the technical intricacies of integrating NeRF technology into the metaverse. The implementation involves the reconstruction of 3D artifact models. The results underscore the potential of NeRF to reshape the cultural heritage landscape by bridging the gap between traditional museums and the boundless possibilities of the metaverse.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"75 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140452245","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}

This capsule layer consists of three main modules: the representation module, the probability module, and the reconstruction module. It transforms the final hidden layer output of BERT into the final activation capsule probabilities to classify the text. By applying the model to sentiment analysis and text classification tasks, and comparing the test results with various BERT variants, the performance across all metrics was found to be superior. Observing the model’s handling of multiple entities and complex relationships, sentences with high ambiguity were extracted to observe the probability distribution of all capsules and compared with RNN-Capsule. It was found that the activation capsule probabilities for BERT-Capsule were significantly higher than the rest, and more pronounced than RNN-Capsule, indicating the model’s exceptional ability to process ambiguous information.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"6 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139958840","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}

However, the sentiment information expressed in texts under different topics varies greatly; for example, a model that performs well on a movie review set has poor model classification on a social platform review set due to inconsistent recognition of antiphonal phrases, different expression of emoji sentiment, and missing contextual information. In this paper, the authors focus on tens of thousands of latest reviews of Chinese takeout platforms Meituan and Elema, and use the LSTM model in deep learning to double classify the data (positive and negative). This paper analyzes the performance of LSTM models in the field of sentiment analysis of takeout reviews and concludes that domain-specific text sentiment analysis requires specific analysis.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139959270","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}

However, in recent years, the development of integrated circuits has encountered more and more limitations, among which the physical characteristics of single-crystal silicon materials are an important reason. With the expansion of integrated circuit scale and the continuous reduction of manufacturing processes, silicon has gradually reached its physical limit. At the same time, silicon has a higher calorific value and a higher performance loss. Therefore, people are actively seeking alternatives to silicon in integrated circuits. This paper reviews the characteristics of three new semiconductor materials, graphene, silicon carbide, gallium nitride, and current research on their applications. Silicon carbide and gallium nitride materials have shown outstanding performance in power-integrated circuits, while graphene has many applications. However, they still have many defects before being used on a large scale. In short, in integrated circuit applications, when new materials replace silicon, many problems remain to be solved.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"24 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140451262","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}
