The pros and cons of different compression methods will be examined by various metrics such as space efficiency, space complexity, and time complexity. Each method will be tested upon various image file types, including BMP, TIFF, PPM, JPG, and PNG. The results indicated that Huffman encoding was particularly effective for PPM images, outperforming RLE and LZ77 with notably higher compression ratios. RLE had slightly higher compression ratios in compressing BMP files. TIFF images exhibit lower compressibility compared to BMP and PPM, but with Huffman encoding still demonstrating superior results. However, when lossless compression algorithms are applied to JPG and PNG images, they yield negative outcomes, indicating that JPG and PNG files have limited compressibility due to prior compression.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"99 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141378179","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 is primarily attributed to the lack of pre-clinical models capable of generating physiologically relevant data essential for accurate predictions during decision-making for advancing to costly clinical stages. Fortunately, advancements in cell culture technology and material fabrication techniques have given rise to an interdisciplinary innovation known as organ-on-chip/body-on-chip (OoC/BoC), offering unparalleled physiological relevance. This review aims to provide a comprehensive overview of the materials and techniques involved in engineering OoC/BoC systems, covering the sourcing of cells from diverse origins, tissue model creation, material processing for culturing these models and coupling single OoCs into complex BoC systems. Furthermore, the potential applications of OoCs/BoCs in drug discovery processes and personalized medicine are explored. Lastly, we discuss the significant potential of this technology to revolutionize the entire drug development pipeline and the way of drug administration, as well as address the key regulatory obstacles impeding the large-scale application of the technology. In summary, this review underlines the pivotal role of OoC/BoC technology in addressing current limitations in drug development, offering promising avenues for improving efficiency, reducing costs, and advancing personalized medicine.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"22 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141378977","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}

The data of this paper comes from the Beijing Statistical Yearbook. By reviewing relevant literature, this paper selects five variables with the highest probability and uses the method of multiple linear regression to analyze these five variables in Beijing in 1999-2018. Considering that the variables will affect each other, this paper also adopts the stepwise regression method to solve the problem of multicollinearity. The final results show that import and export trade and the total retail sales of social commodities in Beijing have a significant impact on Beijing’s GDP. In contrast, the total investment in fixed assets, resident population, and total energy consumption do not pass the significance test. In conclusion, Beijing’s GDP is affected by import and export trade and total retail sales of social commodities in Beijing. Beijing should pay attention to the development of these two factors to further improve its economic strength and competitiveness.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"26 5‐6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381129","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}

The purpose of this paper is to analyze the advantages and disadvantages of multiple supervised learning algorithms and integrated learning algorithms, as well as their applications and performances in predicting users’ purchasing behaviors. The paper concludes that some traditional algorithms have been consistently used due to their simplicity and interpretability, while the more cutting-edge algorithms have a greater advantage in characterizing specific aspects around an innovative core idea. Different algorithms have their own highlights and limitations in prediction, and researchers can choose them according to the dataset and prediction needs. At the same time, this paper emphasizes that combining models that complement each other’s strengths will maximize efficiency and accuracy when using fusion methods. This paper compiles and compares practical machine learning algorithms today, and analyzes the future direction of predictive modeling and areas worthy of further exploration, such as language and image processing, which can provide a reference for enterprises with the need of user behavior prediction in the development of marketing plans.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"11 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381840","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}

{"title":"A review of brake energy recovery systems and vibration energy recovery systems in new energy vehicles","authors":"Hanwen Jian","doi":"10.61173/094x1d72","DOIUrl":"https://doi.org/10.61173/094x1d72","url":null,"abstract":"As the automotive industry faces the dual challenges of energy crisis and environmental degradation, developing new energy vehicles (NEVs) has become a focal point. This paper presents a comprehensive overview of braking and vibration energy recovery systems in NEVs. Specifically, it explores these systems’ theoretical foundations, control strategies, and current research status. The braking energy recovery system aims to enhance energy efficiency by capturing and reusing the energy generated during braking. In contrast, the vibration energy recovery system seeks to expand energy recovery channels by absorbing vehicle vibrations. While considerable research has been conducted on braking energy recovery, there is still a need for further exploration in vibration energy recovery. By optimizing these systems, we aim to contribute to the sustainable growth of the NEV industry, ultimately benefiting both the environment and energy conservation efforts.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141378491","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}
