Ergonomic Evaluation

The rationality of spatial environment design and operational parts’ layout design in ATC (All Terrain Crane) cab needs to provide a quantitative basis through objective evaluation and analysis. In this paper, 3-D space model of ATC cab is constructed in accordance with data provided by a new type of ATC in a famous domestic crane enterprise, and the Chinese human database is established based on Human Dimensions of Chinese Adults(GB10000-88). Besides, the interior design ergonomic evaluation system of ATC cab is created by customizing specific toolbars and dialog boxes with VB language secondary development on CATIA software platform. This system can evaluate comfortable areas and reaching scopes of joystick, seat, pedal, steering wheel and other operating devices and give the evaluation conclusions. This provides a feasible and effective design evaluation method for computer-aided interior design of ATC cab.

The Relationship

The objective of this study was to develop a product evaluation method applicable to virtual prototypes and to apply the method to automobile interior design. Considering that virtual reality-based product prototypes could represent design alternatives comparable to physical prototypes, prototypes developed in virtual reality environments were employed as design alternatives. After a procedure to evaluate virtual prototypes was developed specifically for a virtual reality environment, the procedure was applied to the problem of automobile interior design. 34 subjects evaluated 32 different virtual prototypes generated from the combination of design element variations. Four categories of subjective impression were used to evaluate the 32 virtual prototypes: luxuriousness, comfort, harmoniousness, and controllability. ANOVA and multiple linear regression analysis were performed to specify design elements critical to customer preference and to interpret the relationship between design elements and subjective impressions. As the result, the shapes of frontal area including crash pad and center fascia, door trim and steering wheel were selected as important variables related to subjective impressions. The proposed evaluation method for virtual prototypes could be utilized as an alternative way of identifying the relationship between subjective impressions and design elements.

Abstract In the field of machine vision, image edge detection is an important technology, which can make necessary preparation for the later image processing. Consequently, accurate evaluation of the edge detection effect of the processed image is a more critical technology. In this paper, the new three criteria are proposed, which is based on Canny's three criteria for edge detection. Through theoretical analysis, three quantitative basic evaluation indexes are given to the new three criteria, namely SSIM index of image reconstruction similarity, BIdx index of edge reliability and CIdx index of edge continuity. Additionally, noise evaluation criteria is also considered. Then the four basic evaluation indexes are fused to get the objective evaluation index EIdx of image edge detection.Finally, the experimental data show that the accuracy of the method is better than that of the subjective evaluation system.

In this study, the failure mechanism of crumb rubber–asphalt pavement was analyzed under the combined effects of low temperature, water, and traffic load. The investigation was carried out based on the mechanical and deformational properties of crumb rubber–asphalt mixture and the typical environmental and load conditions such pavement is typically exposed to. A method was proposed for objective evaluation of the interfacial adhesion between rubber crumbs and asphalt through consideration of the effects of the characteristics of the materials and the working environment. The main evaluation method used herein included the indirect tensile strength test under freeze–thaw–boiling cycle, and the Cántabro abrasion test under water-immersion was adopted as an auxiliary method. The evaluation system has the advantages of simple implementation, realistic simulation of the actual working state of the mixture, and reliable results. Moreover, it is a durability evaluation method that can be specifically applied to asphalt mixtures with some special aggregates or stone mastic asphalt (SMA) mixtures.

Competency Evaluation

The development of information technologies changes the learning process. The amount of publicly available data of e-learning systems allows personalized studies. Therefore, the tutor sometimes is needed for the student’s evaluation and consultation only. To ensure clear evaluation requirements and objective evaluation process, the learning material, as well as the evaluation system, must be discrete and semantically expressed. The list of mastered competencies and skills is more important to the enterprise; therefore, during the last years, the study process has concentrated on competency evaluation too. However, the current practice, when students’ competencies are summarized and expressed as one quantitative metric (score), do not express the list of students’ competencies and their level. To solve the problem, in this paper, we proposed a method for the design of competencies’ tree. The competency tree has to be formatted based on context modeling principles and analysis of Scope-Commonality-Variability. The usage of competency tree for students’ competencies’ evaluation proposes clearly defined and semantically expressed evaluation method for both human and e-learning evaluation process. This paper presents the results of the empirical experiment to adapt the proposed competency tree design and application for competencies’ e-evaluation method, based on flexibility, adaptability, and granularity of learning material.

Hole surface quality in drilling carbon fiber-reinforced plastics and titanium alloy (CFRP-Ti) stacks is a key factor affecting high-quality assembly and reliable usage of the structure so it need be reasonably evaluated. However, there is no standardized evaluation system of hole surface quality in drilling CFRP-Ti stacks. The existing evaluation indexes cannot meet the evaluation requirements on the surface quality of the hole. This paper proposes a subjective-objective evaluation method to evaluate the surface quality of the hole in drilling CFRP-Ti stacks. Firstly, the evaluation factors are determined by experiments, including CFRP delamination, CFRP hole entrance tears, surface roughness of CFRP and Ti, and the evaluation system is established according to defect characteristics and industry standards. Secondly, the subjective evaluation model is established based on the improved analytic hierarchy process, the objective evaluation model is established based on the entropy weight method and the subjective and objective combination weight calculation method is obtained based on the principle of minimum discriminant information. Finally, the surface quality of the hole is evaluated by subjective, objective, subjective-objective evaluation methods respectively. The result shows that subjective-objective evaluation method is more reasonable and effective.

Product evaluation is very important for product improvement and development, and subjective product evaluation determines customer’s evaluation of products to some extent, so the purpose of this study is to establish a reasonable subjective product evaluation system. In this study, we comprehensively determine the evaluation indexes based on Kansei engineering (KE), establish an overall product evaluation system by using analytic hierarchy process (AHP), and establish the subjective product evaluation system by classifying the evaluation indexes in the overall product evaluation system into “objective evaluation index” and “subjective evaluation index”, removing the objective evaluation indexes, and retaining the subjective evaluation indexes. Additionally, we select some modern chairs as experimental samples to verify the reliability and validity of this subjective product evaluation system by means of questionnaires. The experimental results show that, in this subjective product evaluation system, the subjective evaluation of the product is positively correlated with the “favorite” level of the product in comprehensive evaluation, and negatively correlated with the “least favorite” level of the product in comprehensive evaluation, indicating that this subjective product evaluation system realizes a symmetry between subjective product evaluation and comprehensive product evaluation. Therefore, it can be concluded that this subjective product evaluation system based on KE and AHP proposed in this study has reliability and validity, and can be used for product evaluation to judge the popularity of products and enhance the competitiveness of products.

Objectives: To perform a systematic study about the contribution of architecture and interior design researchers in studying the effect of physical environment on mental disorders. Background: Mental disorders are a major health problem worldwide and related to severe distress, functional disabilities, and heavy economical burdens. Studies propose that physical environment design can trigger or reduce mental disorder symptoms. However, there is a lack of knowledge about the extent of architectural design research contribution to all types of mental disorder prevention or intervention. Methods: A team of cross-disciplinary researchers gathered information from peer-reviewed manuscripts about the effect of architectural design on enhancing or reducing mental disorder symptoms. Data were collected from manuscripts published between 2008 and 2020 (research related to the topic became clearer in quality and quantity then). Keywords including architecture, interior design, physical environment, and mental disorders were used in the systematic search. Databases were collected using online resources. Numerical data collected from quantitative studies were organized in tables. Results: Our data showed that there were a lot of studies about dementia and autism; few studies about schizophrenia, anxiety, stress-related disorders, and depressive disorders; and no studies about the rest of the mental disorders. General environment followed by housing facility design were the most assessed physical environments for mental disorders. Conclusions: As all mental disorders can have a significant impact on the society, we conclude that architectural studies should focus more on improving or preventing the symptoms of all types of mental disorders through the design of physical environments.
