Journal of Field Robotics, EarlyView.ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Fault Ride-Through Control Strategies of Grid-Forming Inverters Under Grid Faults
Education and Research ArchiveGrid-forming (GFM) inverters are increasingly deployed in modern power systems due to their strong voltage and frequency support capabilities, as well as their high robustness in weak grids. However, unlike traditional synchronous generators with high overcurrent tolerance, GFM inverters can only withstand 1 to 1.5 per-unit of their rated current due ...

The Epistemic Generativity of Using a Model of a Big Idea
Science Education, EarlyView.ABSTRACT Science instruction should involve learners in generating and warranting ideas, what we call epistemic generation. In modeling instruction, epistemic generation should be achieved by coordinating a model structure with the experienced world in reciprocal directions denoted as developing models and using models. In the former, a model structure

Strategic Management Journal, EarlyView.Abstract Research Summary We study how the entry of a rival platform affects the strategies of the incumbent's complementors. The latter face a trade‐off: While the entry threatens their benefits from indirect network effects, it also allows them to escape intense within‐platform competition.

Searching together versus searching apart: Evidence from Kaggle
Strategic Management Journal, EarlyView.Abstract Research Summary How does the mode of search—independently or jointly—affect collective search, a central component of organizational adaptation and innovation? Using naturally occurring data from a strongly incentivized online competition platform, we find that compared to their counterfactuals that search apart, groups searching together ...

Strategic Management Journal, EarlyView.Abstract Research Summary We adopt a network‐based perspective to examine the effects of hiring strategies in terms of the diversity of hiring sources. Considering the transferability of general and firm‐specific skills, we propose that firms can reduce integration costs while gaining diversity benefits when they hire from a focused set of firms that ...
