Current attempts to transpose the problem related to linearity of narrative and temporal flows and audiovisual content obstruction by the interactive layer, although pointing out design perspectives--in addition to the structural and visual web patterns--are still insufficient as regards the design of interfaces connected and converged for t-commerce applications. This article considers that these problems arise from the structural basis that support television scripts and streamings. In this sense, this article proposes the hybridization between the linear model, inherited from analogue condition, and nonlinear model, intrinsic to digital media, as a methodological strategy aiming to strength the creation of interactive audiovisual content connected and convergent for this context.展开更多

The interface was designed to help the remote supervisor to instruct the autonomous sprayer to commence operation, monitor the status of the sprayer and its operation in the field, and intervene when needed (i.e., to stop or shut down). Design principles and guidelines were carefully selected to help develop a human-centered automation interface. Evaluation of the interface using a combination of heuristic, cognitive walkthrough, and user testing techniques revealed several strengths of the design as well as areas that needed further improvement. Overall, this paper provides guidelines that will assist other researchers to develop an ergonomic user interface for a fully autonomous agricultural machine.展开更多

During the process of aircraft design, situation awareness （SA） is frequently considered to improve the design, as the CDI must provide enough SA for the pilot to maintain the flight safety. In order to study the SA in the pilot-aircraft system, a cockpit flight simulation environment is built up, which includes a virtual instrument panel, a flight visual display and the corresponding control system. Based on the simulation environment, a human-in-the-loop experiment is designed to measure the SA by the situation awareness global assessment technique （SAGAT）. Through the experiment, the SA degrees and heart rate （HR） data of the subjects are obtained, and the SA levels under different CDI designs are analyzed. The results show that analyzing the SA can serve as an objective way to evaluate the design of CDI, which could be proved from the consistent HR data. With this method, evaluations of the CDI design are performed in the experimental flight simulation environment, and optimizations could be guided through the analysis.展开更多

文摘Adopting high-voltage Ni-rich cathodes in halide and sulfide-based all-solid-state lithium batteries(ASSLBs)holds great promise for breaking through the 400 Wh kg^(-1)bottleneck.However,both cell configurations are confronted with intricate interfacial challenges in high-voltage regines(>4.5 V),resulting in inadequate cathode utilization and premature cell degradation.Moreover,contrary to previous studies,coupled with LiNi_(0.85)Co_(0.1)Mn_(0.05)O_(2)cathodes,typical halide(Li_(2)ZrCl_(6))-based cells at 4.5 V feature unlimited interfacial degradation and poor long cycle stability,while typical sulfide(Li_(6)PS_(5)Cl)-based cells feature self-limited interfacial degradation and poor initial cycle stability.Herein,this work addresses the high-voltage limitations of Li_(2)ZrCl_(6)and Li_(6)PS_(5)Cl catholyte-based cells by manipulating electrode mass fraction and tailoring interfacial composition,thereby effectively improving interfacial charge-transfer kinetics and(electro)chemical stability within cathodes.After appropriate interface design,both optimized cells at 4.5 V demonstrate remarkably increased initial discharge capacities(>195 mA h g^(-1)at0.1 C),improved cycle stabilities(>80%after 600 cycles at 0.5 C),and enhanced rate performances(>115 mA h g^(-1)at 1.0 C).This work deepens our understanding of high-voltage applications for halide/sulfide electrolytes and provides generalized interfacial design strategies for advancing high-voltage ASSLBs.

文摘Aircraft cockpit display interface （CDI） is one of the most important human-machine interfaces for information perceiving. During the process of aircraft design, situation awareness （SA） is frequently considered to improve the design, as the CDI must provide enough SA for the pilot to maintain the flight safety. In order to study the SA in the pilot-aircraft system, a cockpit flight simulation environment is built up, which includes a virtual instrument panel, a flight visual display and the corresponding control system. Based on the simulation environment, a human-in-the-loop experiment is designed to measure the SA by the situation awareness global assessment technique （SAGAT）. Through the experiment, the SA degrees and heart rate （HR） data of the subjects are obtained, and the SA levels under different CDI designs are analyzed. The results show that analyzing the SA can serve as an objective way to evaluate the design of CDI, which could be proved from the consistent HR data. With this method, evaluations of the CDI design are performed in the experimental flight simulation environment, and optimizations could be guided through the analysis.
