This article is dedicated to the study of the method of various term system analysis from term formation perspective. Herewith as the simple of analysis is studied aerospace terminology in Russian language. The main ways of term formation are divided into four groups: synthetic way, adoption, semantic metaphorization, analytic way. Each way and the nuances of its analysis are explained in detai...

Abstract: The topic of single or multiple objective, optimal control or design has been a very attractive and desirable feature for many dynamic and static systems such as aerospace, electrical, mechanical and robotics, nuclear and aerospace engineering. In particular, in dynamic optimization of nonlinear systems, recent research interest has been the nonlinear, optimal, feedback control using ...

What role do cultural factors play in the survival of a company that faces existential problems, especially if these problems relate to co-operation between organisations with different cultures? We try to provide some answers by looking at the decline of the Dutch aircraft manufacturer Fokker. In 1996 this company went bankrupt and among the causes of this event cultural factors rank high, at ...

Induction of cataracts by occupational exposure in flight crew has been an important topic of interest in aerospace medicine in the past five years, in association with numerous reports of flight-associated disease incidences. Due to numerous confounding variables, it has been difficult to determine if there is increased cataract risk directly caused by interaction with the flight environment, ...

Research supported by NASA Langley Research Center includes many applications of aerospace design optimization and is conducted by teams of applied mathematicians and aerospace engineers. This paper investigates the benefits from this combined expertise in formulating and solving integer and combinatorial optimization problems. Applications range from the design of large space antennas to inter...

Tracking control laws are developed for a rigid spacecraft using both thrusters and momentum wheels. The model studied comprises a rigid body with external thrusters and with rigid axisymmetric wheels controlled by axial torques. Modified Rodrigues parameters (MRPs) are used to describe the kinematics. The thruster torques and the axial motor torques are computed to track given attitude motions...

Distributed systems comprised of autonomous self-interested entities require some sort of control mechanism to ensure the predictability of the interactions that drive them. This is certainly true in the aerospace domain, where manufacturers, suppliers and operators must coordinate their activities to maximise safety and profit, for example. To address this need, the notion of norms has been pr...
