Abstract In this study, 938 consumers in China's Shandong Province were surveyed for their preferences tomatoes a real choice experiment varying three product attributes: food safety label, brand, and price. Using mixed logit model, results revealed that consumer willingness to pay organic was higher than labeled as Green or Generally Regarded Safe (GRS). With regard brands, prefer brands affiliated with proprietary enterprises over held by agricultural cooperatives. The interactions between...

As a reliable waste heat recovery device, the high-temperature pump (HTHP) is increasingly used in industrial enterprises. The selection of refrigerant one most important factors to determine safe, reliability and economic operation HTHP. Starting from this perspective, simple new method based on characteristics extrema volumetric capacity coefficient performance was developed obtain appropriate composition binary mixtures. Then, working fluids including four mixtures with R245fa were...

Intentional or unintentional littering, especially among young people, poses a threat to the marine environment. It is, therefore, necessary enhance awareness of environmental protection youth groups. This study explored interaction between visual image types (photograph vs. cartoon), message framing (positive negative), and psychological distance (human turtle). A three-way analysis variance (ANOVA) regression were used verify hypotheses. The key findings research as follows: (1) Among...

Although there have been many studies on icon preferences and search performances in the past, only a few principles, criteria, guidelines may be applicable to design of icons time- safety-critical interaction (driving) context. This study combines familiarity training task with an icon-semantic meaning recall explore effects format, concreteness drivers' cognitive performance. Icons 3 formats were created as experimental stimuli. Subsequently, 39 participants divided into three groups, each...

Affordance-based design (ABD) plays an important role in identifying interactions, especially effortless ones, between users and artifacts. Cognitive ergonomics extends our understanding of this interaction. This study combines the two methodologies together order to reduce cognitive friction using digital products. The process a compact camera is selected as case that includes physical shape for its user interface. In designing product shape, toolbox was developed integrated modified...

Based on the individual traits of user’s construal level differences, this study examines visual cognition differences graphic–text combined icon concreteness in interface between users with high and low levels. We classified four types icons, which are as follows: concrete graphic + text (Ci Ct), abstract At), (Ai At). According to behavioral experiment results, there is no cognitive difference two Ci Ct. In terms At Ai Ct, performance slightly better than that users. At, obvious Visual...

The identification, selection, and consideration of appropriate affordances during the preliminary design phase a product play critical role in process Affordance Based Design (ABD). A tool named Interactive Genetic Algorithm (ABIGA) evolves products by having designers identify, then users assess affordance qualities virtual prototypes. Affordances are defined to be perceived interactions, both positive negative, primarily between user artifact. In order achieve successful evolution,...

Abstract To lessen users' feelings of unease and stress after icons are updated, this study investigates icon recognition discrimination in terms color location under different working memory (WM) loads. At low WM load, changing the or position has little effect on recognition. The update will affect user's accuracy when less information is presented, but it not participants' reaction time. As for updates, better to icons' positions within same row rather than across rows. high although...

The environmental maintenance of public dining spaces significantly impacts urban construction’s sustainable and healthy development. This paper studied the influence image–text information tailoring relationships on behavioral intentions to promote space environment maintenance. We used a two-factor between-subject experimental design, two (image reference points: self vs. others) × (text appeals: feasibility desirability). also examined mediating roles attitudes responsibility perceptions...

As a simple, discontinuous, surface deformation statistical map, Dorling cartograms are effective means with which to characterize the geographic distribution of event data attributes. According existing research, behavioral differences exist in visual cognition individuals different cognitive field styles spatial task switching layers two-dimensional electronic map. However, there few studies that compare ability cross-layer structure design cartogram information. This paper uses behavior...

Abstract A hybrid dc switch has been studied extensively due to the increasing demand for photovoltaic plants or power distribution systems. The advantages of are low contact resistance and high‐speed interruption. We have demonstrated an arc‐less commutation current from copper‐based tungsten contacts a SiC‐MOSFET. prevents erosion that is one drawbacks conventional mechanical switches. This report shows experiment results on threshold with different material up 400A in switch.

Abstract In this paper, the creep rupture strength for Super304H weld joints was evaluated by isothermal method. Service life prediction curves indicate that could guarante safety service 10 5 hours at 625°C, which is in according with Ultra-supercritical units steam conditions. When stress higher, mode of specimens transcrystalline fracture, and results forming dimples. lower, rupture, cleavage rupture. So under effect long term low stress, cavities joined each other along grain boundary.

Abstract In this paper, the T92 martensitic steel and Super304H austenitic were welded by continuous drive friction welding technique. The joints exhibited good mechanical metallurgical properties. influence of pressure on microstructures properties T92/Super304H dissimilar was investigated. With an increase in pressure, grains zone heat affected didn’t grow up number second-phase particles precipitates increased. Vickers hardness increased impact toughness decreased, tensile fracture...
