A Robust Scheduling Optimization Method for Flight Deck Operations of Aircraft Carrier With Ternary Interval Durations

IEEE Access, 2018
The sortie and recovery operations of the carrier-based aircraft fleet are carried out in a cyclic mode, and there are uncertainties during the flight deck operations, which is the main factor that influences the sustainability of cyclic operations.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

DBO-PSO: Mechanism Modeling Method for the E-ECS of B787 Aircraft Based on Adaptive Hybrid Optimization

Aerospace
In view of the highly coupled, time-varying, and susceptible to differences in aircraft configuration of the Boeing 787 Electric Environmental Control System (E-ECS), a simplified mechanism model based on effectiveness-number of transfer units is ...

‘Brave, Armed and Watchful’: Domestic Militarization and Contested Femininities During the Kenyan Emergency

Gender &History, EarlyView.
ABSTRACT This article examines the militarization of white settler women during the Kenya Emergency (1952–1960), analyzing how their armed participation disrupted and reconfigured colonial gender norms. Drawing on visual and textual archival and newspaper sources, this article explores representations of settler women as maternal guardians of the ...

Using heuristics to solve the dedicated aircraft recovery problem

, 2001
The Dedicated Aircraft Recovery Problem (DARP) involves decisions concerning aircraft to flight assignments in situations where unforeseen events have disrupted the existing flight schedule, e.g. bad weather causing flight delays. The dedicated aircraft recovery problem aims to recover these flight schedules through a series of reassignments of ...

Valorizing Erasure: Imperial Knowledge Production in Anglo‐American Coverage of Chad's ‘Toyota War’

The British Journal of Sociology, EarlyView.
ABSTRACT How does imperial knowledge production operate when Western media coverage of a Global South subject is predominantly admiring instead of hostile? This article addresses that question through critical discourse analysis of sixty‐three Anglo‐American news articles covering the Chad‐Libya conflict of the 1980s, the ‘Toyota War’.

300 Years of Degradation in Wales Estuaries and Coasts

Natural Resources Forum, EarlyView.
ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

INFORMATION-ENERGY METHODOLOGY OF THE AIRCRAFT WITH ELECTRIC PROPULSION ENERGY COMPLEX DESIGN

Научный вестник МГТУ ГА, 2017
Research in the field of aircraft development shows that from the point of view of sustainability and energy efficiency the most acceptable approach is the transition to all-electric aircraft (AEC). Electrification is aimed primarily on the aircraft most

The Questioning of Special Items During Conference Calls: High Quality or Highly Questionable? Réexaminer des éléments exceptionnels lors des conférences téléphoniques : une pratique d'excellence ou très contestable?

Contemporary Accounting Research, EarlyView.
ABSTRACT Accounting standards require firms to distinguish recurring revenues and expenses from nonrecurring gains and losses, which are often referred to as special items. However, not all special items are genuinely nonrecurring. Exploiting the setting of earnings conference calls, we explore whether analysts can identify opportunistic special items,
