Interpreting Development of Unmanned Aerial Vehicles using Systems Thinking

Cosic, Jelena; Curkovic, Petar; Kasac, Josip; Stepanic, … - In: Interdisciplinary Description of Complex Systems - … 11 (2013) 1, pp. 143-152

Rapid present development of unmanned aerial vehicles is rather unstructured. Starting from general systems theory we formulate classification of unmanned aerial vehicles (UAVs) that properly groups diverse produced unmanned aerial vehicles, along with their currently unproduced, yet possible...

Considerable parameters of using PV cells for solar-powered aircrafts

Fazelpour, Farivar; Vafaeipour, Majid; Rahbari, Omid; … - In: Renewable and Sustainable Energy Reviews 22 (2013) C, pp. 81-91

Parameters such as heat transfer, arrangement type, covering and deviation from tilt angle of PV cells located on the wings of a solar-powered aircraft impact on the efficiency, power, flight duration and costs of the solar flyer. The objective of this paper is to represent these parameters and...

Politics & technology: U.S. polices restricting unmanned aerial systems in agriculture

Freeman, P.K.; Freeland, R.S. - In: Food Policy 49 (2014) P1, pp. 302-311

Many industry observers foresee that agriculture worldwide is posed to substantially benefit from the use of unmanned aircraft systems (UASs), commonly known as drones. Industry special interests predict that 80% of domestic sales of UASs in the U.S. will be for agriculture. However, some fear...

Linearisierungsverfahren für Standortplanungsprobleme mit nichtlinearen Transportkosten

Stolletz, Raik; Stolletz, Lars - In: Metrika 19 (2008) 3, pp. 261-280

This paper analyzes the Steiner–Weber-Problem with piecewise linear or piecewise constant transportation costs. These non-differentiable cost functions are analyzed using different one-step and dynamic linearization methods, which are based on approximations via average and marginal costs. An...

Isodistant points in competitive network facility location

Pelegrín, Blas; Suárez-Vega, Rafael; Cano, Saúl - In: TOP: An Official Journal of the Spanish Society of … 20 (2012) 3, pp. 639-660

An isodistant point is any point on a network which is located at a predetermined distance from some node. For some competitive facility location problems on a network, it is verified that optimal (or near-optimal) locations are found in the set of nodes and isodistant points (or points in the...

A cutting plane algorithm for the Capacitated Connected Facility Location Problem

Gollowitzer, Stefan; Gendron, Bernard; Ljubić, Ivana - In: Computational Optimization and Applications 55 (2013) 3, pp. 647-674

We consider a network design problem that arises in the cost-optimal design of last mile telecommunication networks. It extends the Connected Facility Location problem by introducing capacities on the facilities and links of the networks. It combines aspects of the capacitated network design...
