Introducing an efficiency index to evaluate eVTOL designs

نویسندگان

چکیده

The evolution of electric vertical takeoff and landing (eVTOL) aircraft as part the Advanced Air Mobility initiative will affect our society environment in fundamental ways. Technological forecasting suggests that commercial services are fast emerging to transform urban regional air mobility for people cargo. However, complexities diverse design choices pose a challenge potential adopters or service providers because there no objective simple means compare designs based on available set performance specifications. This analysis defines an aeronautically informed propulsion efficiency index (PEX) eVTOL designs. Range, payload ratio, aspect ratio minimum independent parameters needed compute PEX can distinguish among distribution range lognormal space. There is association between values mainstream architecture types weight class. A multilinear regression showed three explained >90 % present

Simulations to Evaluate HIV Vaccine Trial Designs

population level by altering the infectiousness of vaccinated individuals who become infected. A vaccine trial design that does not estimate both susceptibility and infectiousness might reject a proposed vaccine that is capable of halting the HIV epidemic. We describe a vaccine trial design called the Retrospective Partner Trial (RPT), which can quantify vaccine effects on both susceptibility a...

Introducing An Efficient Set of High Spatial Resolution Images of Urban Areas to Evaluate Building Detection Algorithms

The present work aims to introduce an efficient set of high spatial resolution (HSR) images in order to more fairly evaluate building detection algorithms. The introduced images are chosen from two recent HSR sensors (QuickBird and GeoEye-1) and based on several challenges of urban areas encountered in building detection such as diversity in building density, building dissociation, building sha...

An index to evaluate the quality of taxonomic publications

The number of citations is not an adequate measure of taxonomic quality, which is a view that is shared with other scientific disciplines (Seglen1997; Valdecasas et al. 2000; Walter et al. 2003). A recent editorial in Nature claims that “... citations are an unreliable measure of importance" (Anon. 2010: 850) and uses two chemistry papers as an example. The first paper was cited 182 times in th...

Proposal for an index to evaluate dichotomous keys

Dichotomous keys are the most popular type of identification keys. Studies have been conducted to evaluate dichotomous keys in many aspects. In this paper we propose an index for quantitative evaluation of dichotomous keys (Edicho). The index is based on the evenness and allows comparing identification keys of different sizes.
