Impact of tail loss on the behaviour and locomotor performance of two sympatric Lampropholis skink species. [PDF]

open access: yesPLoS ONE, 2012
Caudal autotomy is an anti-predator behaviour that is used by many lizard species. Although there is an immediate survival benefit, the subsequent absence of the tail may inhibit locomotor performance, alter activity and habitat use, and increase the ...

Sustainable development of territorial units: MCDM approach with optimal tail selection

open access: yesEcological Modelling, 2021
Abstract In the face of accelerating climate change, economic instability and limited resources, it is essential to find indicators that better measure the sustainable development of territorial units. Despite ambiguous definitions of sustainable development, numerous studies describe quantitative indicators of sustainable development.

An extended TDM method under probabilistic interval-valued hesitant fuzzy environment for stock selection.

open access: yesPLoS ONE, 2021
Generally, in real decision-making, all the pieces of information are used to find the optimal alternatives. However, in many cases, the decision-makers (DMs) only want "how good/bad a thing can become." One possibility is to classify the alternatives ...

Analytical Modeling and Design of Novel Conical Halbach Permanent Magnet Couplings for Underwater Propulsion

open access: yesJournal of Marine Science and Engineering, 2021
Permanent magnet couplings can convert a dynamic seal into a static seal, thereby greatly improving the stability of the underwater propulsion unit. In order to make full use of the tail space and improve the transmitted torque capability, a conical ...

Tail risk adjusted clean energy portfolios in P2P transactive markets using Rachev ratio

open access: yesEnergy Conversion and Economics, 2023
Renewable energy sources (RES) and electric vehicles (EVs) pose ‘energy‐risk’ in peer energy commitments due to their temporal and spatial uncertainties. Thus, optimistic commitments in the peer‐to‐peer transactive energy market (P2P TEM) are improbable.

Development of E-rickshaw driving cycle (ERDC) based on micro-trip segments using random selection and K-means clustering techniques

open access: yesIATSS Research, 2021
In India, auto rickshaws are the most convenient and cheapest mode of near-to-door transport in both rural and urban areas. Such vehicles powered with internal combustion engines (ICEs) are one of the main sources of pollutants on urban corridors.

Threshold selection and trimming in extremes

open access: yes, 2020
We consider removing lower order statistics from the classical Hill estimator in extreme value statistics, and compensating for it by rescaling the remaining terms. Trajectories of these trimmed statistics as a function of the extent of trimming turn out
