This paper deals with a novel scheme for microclimate control in historical exhibition rooms, inhibiting moisture sorption phenomena that are inadmissible from the preventive conservation point of view. The impact of air humidity is the most significant h... see more
D. Telfer,J. Spencer
This work is an extension to that of Telfer and Austin [1] in that here a balanced feed embodiment of an inwardly-inclined folded dual monopole aerial is presented and discussed in terms of its improved performance over the original configuration. This in... see more
A. J. Mitchell,E. W. McGookin,D. J. Murray-Smith
This paper looks at the implementation of a Sliding Mode Observer (SMO) based Reconfiguration algorithm to deal with sensor faults within the context of navigation controllers for Autonomous Underwater Vehicle (AUV). In this paper the reconfigurability as... see more
J. A. Walker,C. Cossar,T. J. E. Miller
Modern permanent magnet (PM) synchronous brushless machines often have magnetic circuits in which the patterns of saturation are complex and highly variable with the position of the rotor. The classical phasor diagram theory of operation relies on the ass... see more
J. Bíla,M. Tlapák
This paper discusses ontologies, methods for developing them and languages for representing them. A special ontology for computational support of the Conceptual ReDesign Process (CRDP) is introduced with a simple illustrative example of an application. Th... see more
C. Peebles,C. Bil,L. Drack
This paper documents the findings of a literature review conducted by the Sir Lawrence Wackett Centre for Aerospace Design Technology at RMIT University. The review investigates aspects of a proposed system for intelligent design optimisation. Such a syst... see more
R. E. Crosbie,N. G. Hingorani
The use of computer simulations is now an established technique in engineering design. Many of these simulations are used to predict the expected behavior of systems that are not yet built, or of existing systems in modes of operation, such as catastrophi... see more
T. S. Ericsen
This paper discusses the expanding role of modeling and simulation in the design and development of electrical power systems. The concepts of physics-based design and building blocks are introduced to show how complex systems may be simplified. However, t... see more
M. Hrouzek
This paper offers a concise survey of the most commonly used feedback loops for atomic force microscopes. In addition it proposes feedback control loops in order to minimize the effect of thermal noise on measurements of weak forces, and to improve the ma... see more
D. P. Coiro,A. de Marco,F. Nicolosi,N. Genito,S. Figliolia
The paper deals with the design of an aircraft, starting from a market survey, the conceptual design loop and the preliminary choice of dimensions, and leading to the detailed design of efficient high-lift systems and a low-drag fuselage shape. Technologi... see more
G. Avanzini,S. D’Angelo,G. de Matteis
Advanced computer-aided technologies played a crucial role in the design of an unconventional Uninhabited Aerial Vehicle (UAV), developed at the Turin Technical University and the University of Rome “La Sapienza”. The engine unit of the vehicle is made of... see more
D. J. McGeoch,E. W. McGookin,S. S. Houston
This paper presents an investigation into the design of a flight control system, using a decoupled non-linear sliding mode control structure, designed using a linearised, 9th order representation of the dynamics of a PUMA helicopter in hover. The controll... see more
V. Zanic,P. Prebeg
A concept design methodology for monotonous, tapered thin-walled structures (wing/fuselage/ship/bridge) is presented including modules for: model generation; loads; primary (longitudinal) and secondary (transverse) strength calculations; structural feasib... see more
R. Poul,D. Hanus
This work focuses on the design of an axial flow ducted fan driven by a reciprocating engine. The solution minimizes the turbulization of the flow around the aircraft. The fan has a rotor - stator configuration. Due to the need for low weight of the fan, ... see more
P. Kanovský,L. Smrcek,C. Goodchild
The study described in this paper deals with the issue of a design tool for the autopilot of an Unmanned Aerial Vehicle (UAV) and the selection of the airdata and inertial system sensors. This project was processed in cooperation with VTUL a PVO o.z. [1].... see more
