Evaluation of the ventilation system in an LNG cargo tank construction platform (CTCP) by the AHP-entropy weight method

Owing to the vulnerability of Invar to moisture in the membranes of LNG tanker cargo tank construction platforms(CTCPs),an energy-efficient ventilation system is needed to maintain a suitable thermal-moisture environment and a healthy workplace.However,the optimal distribution of supply and return devices that would guarantee worker satisfaction,air quality,and energy efficiency is unclear.Therefore,we conducted numerical simulations to determine the worker satisfaction indices(temperature,relative humidity,and carbon monoxide concentration satisfactions),air quality index(contaminant-removal efficiency),and energy efficiency index(heat-removal efficiency)with supply vane angles ranging from-75°to 0°and two return vent positions(the bottom return vent and the top return vent).The analytic hierarchy process(AHP)entropy weight method was employed to determine the optimal supply vane angle and return vent position for three design targets by considering these indices simultaneously.The results indicated that,with a supply angle of-45°and a bottom return vent,worker satisfaction and air quality were prioritized.Furthermore,a high energy performance of the ventilation system was achieved with a-15°supply angle and a bottom return vent.Moreover,a comprehensive graph of supply vane angles at both return heights,which could provide a reference for optimizing the ventilation system in LNG-CTCPs,is described.

Research on the Construction of a Fully-participatory Extracurricular Learning Platform with Multiple Linkage Effects

In the existing research at home and abroad,the construction of extracurricular learning platform is still only focused on solving the problems of curriculum learning itself.At the same time,there are no cases of multiple linkage effects,including integrating alumni resources,promoting the construction of alumni association,promoting students'internship and employment,strengthening ties with enterprises and so on.On the basis of the original function of the alumni management system,this paper expands the sections and adds the main body of students to enrich the functions of the platform.This paper constructs a fully-participatory extracurricular learning platform with multiple linkage effect,which provides a reference for other majors inside and outside the school to establish extracurricular learning platform.

Overview of Construction and Application of Big Data Analysis Platform

Big data technology is widely spread around the world,and is constantly developing and applying.In order to enhance the application value of big data analysis platform,it is necessary to constantly improve the data analysis and processing capacity of big data platform,so as to build a complete data analysis platform,realize resource sharing and real-time data collection.As a key point of contemporary information development,big data analysis platform is of great significance to promote social data exchange.Based on this,this paper focuses on two aspects:first,it describes the construction process and content of big data platform;second,it summarizes the relevant application and development of big data platform for reference.

Construction of a blockchain-based intelligent platform for government data

The management and application of government data are the bases for the construction of a digital government.Building an intelligent platform for government data by using artificial intelligence,blockchain,and other technical means to achieve open sharing,development,and utilization of data is an important link to promote continuously the construction of a digital government and improve the level of government management and service efficiency.According to the current construction status of government data platforms and the application prospect of blockchain technology,this study proposes to build a blockchain-based intelligent platform for government data.In combination with the technical advantages of blockchain,this study investigates the theory and technical logic of building a blockchain-based intelligent platform for government data and then proposes the theoretical model,architecture,operation mechanism,and core technology of platform construction.This study explores sthe implementation path of building a blockchain-based intelligent platform for government data from five aspects,i.e.,promoting technology upgrading,improving top-level design,strict supervision and regulation,strengthening collaborative research and judgment,and improving technical support.

A Win-Win Undergraduate Graduation Design Model for Students, Teachers, and Training Platforms

Undergraduate graduation design is an important link in the process of undergraduate training,and university platforms have invested a lot of manpower and material resources for this purpose.However,while carrying out student training,it has gradually become the consensus of most university platforms to achieve a win-win situation for teachers and training platforms in order to achieve optimization of resource allocation and motivation of student training.After discussion and practice,this paper proposes a set of undergraduate graduation design training concepts and training modes with a win-win situation for students,teachers,and training platforms.

Construction of the Chinese Veteran Clinical Research （CVCR） Platform for the assessment of non-communicable diseases

Background Based on the excellent medical care and management system for Chinese veterans,as well as the detailed medical documentation available,we aim to construct a Chinese Veteran Clinical Research （CVCR） platform on noncommunicable diseases （NCDs） and carry out studies of the primary disabling NCDs.Methods The Geriatric Neurology Department of Chinese People＇s Liberation Army General Hospital and veterans＇ hospitals serve as the leading and participating units in the platform construction.The fundamental constituents of the platform are veteran communities.Stratified typical cluster sampling is adopted to recruit veteran communities.A cross-sectional study of mental,neurological,and substance use （MNS） disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment,followed by systematic neuropsychological assessments to make clinical diagnoses,evaluated disease awareness and care situation.Results A total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform,yielding a response rate of 83.86％.8 812 subjects complete the MNS subproject screening and total response rate is 91.70％.The average participant age is （82.01±4.61） years,69.47％ of veterans are 80 years or older.Most participants are male （94.01％）,83.36％ of subjects have at least a junior high school degree.The overall health status of veterans is good and stable.The most common NCD are cardiovascular disorders （86.44％）,urinary and genital diseases （73.14％）,eye and ear problems （66.25％）,endocrine （56.56％） and neuro-psychiatric disturbances （50.78％）.Conclusion We first construct a veterans＇ comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans.The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.

Construction of a virtual lunar environment platform

Many of the world’s powerful and wealthy nations,including China,have devoted both large amounts of funding and considerable promotion to lunar research and exploration.The launch of Chinese Chang’e-1 satellite and the construction of the scientific observation data platform created a favourable opportunity for research into the lunar geometrical,physical and chemical environment.Based on this background,a Wide Area Network(WAN)based virtual lunar environment was constructed for observation data sharing and further exploration.The systematic architecture and framework were introduced and then strategies of mass data(e.g.lunar digital elevation model,lunar digital orthophoto map and typical thematic lunar data)organisation,integration,management and scheduling were then set up to achieve the 3D visualisation of typical lunar geomorphic features.Furthermore,the integration method of 3D lunar data and the process model of impact craters were studied;thus,the whole lunar and celestial collision process could be dynamically simulated.The results indicate that the WAN-based virtual lunar platform can be used effectively for public information sharing,scientific exploration and further to promote the development of deep space exploration in China.
