A De-biased Direct Question Approach to Measuring Consumers' Willingness to Pay [PDF]

open access: yes, 2020
Knowledge of consumers' willingness to pay (WTP) is a prerequisite to profitable price-setting. To gauge consumers' WTP, practitioners often rely on a direct single question approach in which consumers are asked to explicitly state their WTP for a ...

Time-Aware Monitoring of Overhead Transmission Line Sag and Temperature with LoRa Communication

open access: yesEnergies, 2019
The techniques of Dynamic Line Rating (DLR) for Overhead Transmission Line (OTL)’s are currently dynamically developed. DLR systems typically rely on weather, temperature, inclination, and current measurements to calculate tension and sag, where ...

Convective Heat Loss Prediction Using the Concept of Effective Wind Speed for Dynamic Line Rating Studies

open access: yesEnergies
Dynamic line rating (DLR) is an effective technique for real-time assessments on current-carrying capacities of overhead lines (OHLs), improving efficiencies and preventing overloads of transmission networks.

Ground verification of the feasibility of telepresent on-orbit servicing [PDF]

open access: yes, 2009
In an ideal case telepresence achieves a state in which a human operator can no longer differentiate between an interaction with a real environment and a technical mediated one. This state is called transparent telepresence.

Thermal Plasticity is Regulated by a Key MicroRNA During Range Expansion of an Invasive Fruit Fly

open access: yesAdvanced Science, EarlyView.
Populations at the invasion front of Bactrocera dorsalis adapt through reduced phenotypic and gene expression plasticity, a phenomenon likely to be driven by genetic assimilation. We identify a key miRNA‐mediated regulatory axis, in which miR‐276b post‐transcriptionally represses thw, a conserved chitin‐binding gene critical to the cold‐tolerance ...

Improved current differential protection scheme for active distribution network integrated with dynamic line rating

open access: yesInternational Journal of Electrical Power & Energy Systems
With the massive access of inverter-interfaced distributed generator (IIDG), the new active distribution network is facing problems such as the inability to effectively utilize new energy and the lack of adaptability of protection schemes.
