Nowadays, One-Dimensional Cutting Stock Problem (1D-CSP) is used in many industrial processes and re-cently has been considered as one of the most important research topic. In this paper, a metaheuristic algo-rithm based on the Simulated Annealing (SA) method is represented to minimize the trim loss and also to fo-cus the trim loss on the minimum number of large objects. In this method, the 1D-...

Performance characteristic of an Unmanned Air Vehicle (UAV) is investigated using a newly developed heuristic approach. Almost all flight phases of any air vehicle can be categorized into trim and maneuvering flights. In this paper, a new envelope called trim-ability envelope, is introduced and sketched within the conventional flight envelope for a small UAV. Optimal maneuverability of the inte...

The flight envelope can be viewed as a set within the state space of an aircraft. For various safety considerations an aircraft is required to remain within its prescribed flight envelope. The safe set is the largest controlled invariant set within the flight envelope. Thus, if an aircraft is to remain within its envelope it must stay within the safe set. When an aircraft is impaired, e.g., a j...

An automatic rotor trim control system was developed and successfully used during a wind tunnel test of a full-scale UH-60 rotor system with Individual Blade Control (IBC) actuators. The trim control system allowed rotor trim to be set more quickly, precisely and repeatably than in previous wind tunnel tests. This control system also allowed the rotor trim state to be maintained during transien...

OBJECTIVES British forces have a comprehensive system for managing acute psychological distress in a combat zone. This includes peer support via Trauma Risk Management (TRiM), access to deployed medical personnel, and a Field Mental Health Team (FMHT). TRiM and medical personnel need to be aware of the FMHT's presence in the combat zone and capability to provide specialist mental health care. ...

A MANET is a group of wireless, mobile, battery-powered clients and servers that autonomously form temporary networks. Increasingly, research in MANET data communication has been addressed. Three data communication modes can be provided in a MANET, data broadcast, data query, and peer-to-peer messaging. Currently, no MANET data communication protocol provides the ability to use all MANET data c...

Adjusting a vessel's trim and draught to enhance resistance characteristics is promising strategy improve the energy efficiency of maritime transport. However, vast majority scientific effort has been directed at such gains in deep, unrestricted waters. Shallow confined waters modify flow pressure distribution around ship, altering considerably curve. This study aims elucidate increase effects ...

A Mobile Ad-Hoc Network (MANET) is a group of wireless, mobile, battery-powered clients and servers that autonomously form temporary networks. Three data communication modes can be provided in a MANET, data broadcast, data query, and peer-to-peer messaging. Currently, no MANET data communication protocol provides the ability to use all MANET data communication modes. The objective of this resea...
