In aviation, it is common to have several aircraft operating in similar conditions uneventfully, yet another aircraft, following suit, experiences an accident in the same conditions. With the same information availabl...
This paper considers the possibility of estimating continuous-time linear aircraft models by using the subspace identification The outline of the subspace identification for estimating the continuous-time linear model...
The adaptive power control of CDMA (Code Division Multiple Access) communications between multiple MSs (Mobile Stations) with a link-budget based SIR (Signal-to-lnterference Ratio) estimate is applied to inner l...
Full nonlinear mathematical model for a mini helicopter is very complex, inflexible and has big influence on the designed control system performance. Analytical approach for autonomous helicopter modeling including bo...
The successful development of new high performance materials and actuators enable the controlled deformation of aerodynamic profiles for wing like type of structures. This paper presents the studies and conclusions of...
Highly concentrated hydrogen peroxide has been widely used as a rocket mono-propellant and oxidiser since 1940's. Although the relevant specialist literature concerning HTP is relatively extensive, one can still find...
FSC (Fractionated Spacecraft Cluster) is a kind of loosely distributed space system which is comprised of multiple physically independent spacecrafts orbiting closely and interactively communicating via wireless net...
This study examines the prenoon-postnoon asymmetrical behaviour and latitudinal dependence of Sq (solar quiet) current system using data of quiet-time daily variations of the geomagnetic field intensity from twelve ...

An experimental study was conducted on the interactions of shock wave/turbulence or laminar boundary layer caused by fin-type protuberance, as the lack of detailed understanding of fluctuating pressure loads inside an...
The primary purpose of this study is to exploit the effect of Earth's non-sphericity perturbation, particularly due to the J2 term, in order to optimize the capture sequence of potential orbital debris, that is the c...
