Time-domain Analytical Method for Aeroelastic Analysis of High Aspect Ratio Wing Using Unsteady Indicial Aerodynamics [PDF]

open access: yesINCAS Bulletin, 2022
This paper deals with the development of a novel time-domain analytical method to perform an aeroelastic stability analysis of a high aspect ratio wing. The aerodynamic model in this paper is built upon the frequency domain of Theodorsen aerodynamics. An

Lift Charts-Based Binary Classification in Unsupervised Setting for Concept-Based Retrieval of Emotionally Annotated Images from Affective Multimedia Databases

open access: yesInformation, 2020
Evaluation of document classification is straightforward if complete information on the documents’ true categories exists. In this case, the rank of each document can be accurately determined and evaluated.

A Short Note on a Mus-Cheeger-Gromoll Type Metric

open access: yesJournal of New Theory, 2023
In this paper, we first show that the complete lift $U^{c}$ to $TM$ of a vector field $U$ on $M$ is an infinitesimal fiber-preserving conformal transformation if and only if $U$ is an infinitesimal homothetic transformation of $(M,g)$.

Research on transition corridor boundary of distributed propulsion VTOL fixed wing

open access: yesXibei Gongye Daxue Xuebao, 2022
The transition state is the most critical and dangerous state of the VTOL fixed wing aircraft in the whole flight process. In this paper, a transition corridor for a distributed propulsion VTOL fixed-wing aircraft is studied based on the lift ...

Radiographic comparison of density and height of posterior maxillary bone after open sinus lift surgery with and without PRF [PDF]

open access: yesJournal of Advanced Periodontology and Implant Dentistry, 2018
Background and aims. Expansion of maxillary sinus towards the alveolar crest due to tooth loss or horizontal‒vertical resorption of the alveolar bone decreases the available bone for the placement of dental implants in the posterior maxilla.

“Surgical and prosthetic management of a severely atrophic maxilla, using nasal and sinus lifts along with incisive canal implants”.A case report

open access: yesOral and Maxillofacial Surgery Cases, 2021
The present case report describes the dental rehabilitation of an atrophic maxilla in a 70-year-old female without a relevant medical record. The patient presented three-dimensional bone reabsorption of the upper alveolar ridge, altered intermaxillary ...

On a class of exact locally conformal cosymlectic manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
An almost cosymplectic manifold M is a (2m+1)-dimensional oriented Riemannian manifold endowed with a 2-form Ω of rank 2m, a 1-form η such that Ωm Λ η≠0 and a vector field ξ satisfying iξΩ=0 and η(ξ)=1. Particular cases were considered in [3] and [6].

Study on Root Hydraulic Lift of Drought-Tolerant and Drought-Sensitive Potato Cultivars (Solanum tuberosum L.)

open access: yesAgronomy, 2023
In order to investigate the relationship between hydraulic lift and drought tolerance in potato, four cultivars differing in drought susceptibilities were selected, and a pot experiment with three different irrigation conditions was carried out in a ...
