Metro Environmental Assessment and Analysis Based on Inclusive Design

Under the background of accelerating urbanization, increasing aging population and decreasing fertility rate in China, all sectors of society eager for an elderly-and-children friendly environment. As public transportation, the metro is at the frontline. This article takes promoting the inclusive design of the metro environment as the research goal, inclusive design as the research perspective and progressive research as the research method. It analyzes the significance of the inclusive design of metro through pyramid theory, employs personas classification to define the inclusive group, and includes user journey to explore the touch-point of metro ride experience so as to propose a metro inclusiveness evaluation kit. With the help of the toolkit, six metro lines and 42 stations in Hangzhou were evaluated and analyzed by using the method of mobile ethnography. Based on the macro and micro analysis of horizontal comparison, it offers solutions to Hangzhou Metro’s existing problems and optimizes the inclusive performance, which can provide direction for the evaluation and optimization of the inclusive design of domestic metro construction.

AI-Based Culture Independent Pervasive M-Learning Prototype Using UI Plasticity Design

This paper explains the development of a culturally inclusive ubiquitous M-Learning platform(“Mobile Academy”)with an AI-based adaptive user interface.The rationale and need for this research and development are justified by the continuing widespread adoption of the Internet and Internet enabled devices,especially smartphones.The M-learning platform was designed from the onset for the global traveller.The characteristics and limitations of the application are also discussed.The Mobile Academy,proof of concept prototype,was created to facilitate teaching and learning on the move or in environments where the use of a desktop computer is inconvenient or simply impossible.The platform’s primary objective was cross-cultural usability through the use of a combination of AI and plasticity of user interface design techniques.The usability evaluation plan was comprehensive and the results obtained were studied in detail.This also included consideration of the results of the SVM(Support Vector Machine)classifiers’performance and cross-device evaluation.The AI-based adaptive interface prototype has been tested and evaluated to show its merits and capabilities in terms of its usability,inclusivity and effectiveness of the interface.From the results,it was concluded that such a culture independent application was also affordable.

An Ergonomics Study and Rapid Upper Limb Assessments(RULA)for a Car Interior to Support Limb Disabled Drivers

The demanding market shows that the need for the disabled vehicles have been increasing over the recent years.However,these factory setting cars are pricey,and its buy-sell process is time-consuming.These cars also are not meant as a universal design or inclusion design type of car,so that when it is designed for the disabled,it can be beneficial for all.With the motivation to include limbs disabled drivers in designing a universally designed car,this study aims to determine the preferred ergonomics interior of the car which can improve features needed to meet the mobility of impaired individuals in most scenarios.5 simulations were carried out to simulate these conditions using the RULA analysis,in order to simulate the ergonomics impact on the manikin.In the final analysis,the simulations showed a virtuous score,which was between 1 and 2 for the newly redesigned interior,compared to the score of 3 to 6 for current cars.Another verification made,post questionnaire delineates positive responses upon the redesigned parts scoring 70%~90% level of ergonomics rated.Therefore,this research has set forth the necessity of redesigning a car interior and improved its ergonomic features extensively,specifically for lower limb and combined limb disabled drivers.

Purifying Fe-based amorphous alloys to enhance glass-forming ability by designing a novel refining slag

Designing low melting point and low basicity refining slag suitable for Fe-based amorphous alloys and understanding the inclusions’formation,removal,influencing mechanisms are quite vital in the fields of metallurgy and materials.In this study,a novel 13%SiO_(2)-32%CaO-30%Al_(2)O_(3)-25%B_(2)O_(3)(wt.%)refining slag was designed after careful calculations of the liquid phase region,slag-metal equilibrium,surface tension,viscosity,deoxidation capability and sulfur distribution ratio.After refining with our designed slag,the content of impurities and the number density of inclusions in a representative Fe_(83)Si_(2)B_(15)(at.%)amor-phous alloy were significantly reduced.Moreover,the glass-forming ability(GFA)of the alloy was also enhanced,enabling the preparation of amorphous ribbons with a lower cooling rate.Based on the impu-rities in Fe-based amorphous alloys as well as the calculated oxide and sulfide free energy diagrams,CaO,SiO_(2),Al_(2)O_(3) oxides and CaS,TiS,MnS sulfides will form in the master alloy.The high melting point in-clusions in the melt are generally removed via a floatation-separation-absorption process and the Mn,Ti,S impurities are removed via slag-metal interface reactions during refining.As for the detrimental effect of inclusions on glass formation,the small lattice disregistry between Ti,Mn-containing inclusions and primaryα-Fe gains reveal that these inclusions are effective in promoting the heterogeneous nucleation,and therefore greatly deteriorate the GFA.These findings are important and provide an ideal solution to purifying the Fe-based amorphous alloys by refining and enhancing the GFA for industrial production.
