The proliferation of electrical and electronic products in modern lifestyles has led to a significant increase in standby power consumption, posing a challenge for energy conservation efforts. In response, this study explores the potential of user-centric design methodologies in addressing standby power management and energy efficiency. By analyzing human error categories and user interaction behavior, the research aims to identify design gaps and develop strategies for mitigating human errors in standby power usage. Through an exploratory and explanatory approach, data gathered from questionnaires provide insights into users' habits, needs, attitudes, and reflections related to standby power consumption. The findings highlight the potential for user-centric approaches to effectively control standby power in connected appliances, paving the way for future advancements in appliance design that prioritize user behavior and preferences. This study offers a novel perspective on standby power management, emphasizing the importance of human error alleviation and user-centric design in achieving energy efficiency goals.

Bipolar plates (BPPs) play an important role in PEM fuel cells in terms of weight and cost points of view. In this paper, the manufacturing of titanium BPPs with parallel flow field was experimentally and numerically studied. In this regard, a stamping die with a parallel pattern is conducted to perform the experiments. Then, the process was modeled via the finite element (FE) simulation. By comparing simulation and experiment results, it was found that the results are in good agreement and hereupon, the accuracy of the FE model was verified. To evaluate the sheet formability, a set of FE experiments was designed through the response surface methodology (RSM). The die clearance, forming velocity, and friction coefficient were considered input parameters, and the maximum thickness reduction (MTR) of the sheet was assumed to be the output. The results revealed that a lower friction coefficient causes an increase in thickness reduction and finally tearing in the formed BPPs. Moreover, changing the forming velocity has no remarkable influence on the MTR. Afterward, an Adaptive Neuro-Fuzzy Inference System (ANFIS) was trained for predicting the output of the MTR with the three mentioned inputs.
