Stabilization of an Unconventional Large Airship When Hovering
Applied Sciences, 2021 In this paper, we present the stabilization of an unconventional unmanned airship above a loading and unloading area. The study concerns a quad-rotor flying wing airship. This airship is devoted to freight transport.

The economics of garbage collection [PDF]
, 2010 This paper argues that economic theory can improve our understanding of memory management. We introduce the allocation curve, as an analogue of the demand curve from microeconomics.

Resource allocation, hyperphagia and compensatory growth [PDF]
, 2004 Organisms often shown enhanced growth during recovery from starvation, and can even overtake continuously fed conspecifics (overcompensation). In an earlier paper (Ecology 84, 2777-2787), we studied the relative role played by hyperphagia and resource ...

Constrained Control Design for Dynamic Positioning of Marine Vehicles with Control Allocation [PDF]
Modeling, Identification and Control, 2009 In this paper, we address the control design problem of positioning of over-actuated marine vehicles with control allocation. The proposed design is based on a combined position and velocity loops in a multi-variable anti-windup implementation together ...

Can’t Buy Me Rights! The Contractual Structure of Asymmetrical Inter-firm Collaborations [PDF]
, 2006 The efficient allocation of control rights in inter-firm collaborations is a widely emphasized issue. In this paper, I empirically identify control rights and the allocation of these rights using a unique survey data set on collaborations between ...

Analysis and Management of Motor Failures of Hexacopter in Hover
Actuators, 2021 This research presents an analysis and management strategy for hovering hexacopter with one or more failing motors. Of late, multirotor drones have become particularly popular, and all drones have been increasing in popularity. Unlike a fixed-wing drone,

Computationally efficient control allocation [PDF]
Guidance, Navigation, and Control Conference and Exhibit, 1999 A computationally efficient method for calculating near-optimal solutions to the three-objective, linear control allocation problem is disclosed. The control allocation problem is that of distributing the effort of redundant control effectors to achieve some desired set of objectives. The problem is deemed linear if control effectiveness is affine with
