In this paper, a robust and optimal control method is proposed for the attitude control problem of multirotors. The designed controller consists of an optimal controller and a robust compensator. The optimal controller is designed based on the linear quadratic regulation control method for the desired tracking of the nominal linear system, whereas the robust compensator is introduced to restrai...

Ann Saudi Med 2006;26(4):306-309 Magnetic resonance imaging (MRI) has been in clinical use for more than two decades. At the time of introduction of this important diagnostic tool, there were many concerns about its safety and the effects of the different types of magnetic fields utilized in MRI on the body tissues. Safety of MRI in pregnancy, however, was and still is one of the important conc...

A three dimensional reorientation problem for an underactuated multi-body spacecraft is studied. Formulae for approximating the change in orientation of the base body of the spacecraft, induced by appropriately constructed small amplitude periodic joint motions, are derived. These formulae are used to construct joint motions that cause a desired reorientation maneuver to be performed within a p...

The observability of space object attitude from light curve data is analyzed. Light curves, which are the time-varying apparent brightness of sunlight reflected off a space object and measured by an observer, depend on the object position, attitude, surface material, shape, and other parameters. Previous work employing light curve data for shape estimation requires the availability of good atti...

Theavailability of diverse information does not guarantee that a person’s views will be equally diverse. Research has consistently shown that attitudinal positions on an issue will lead to selective reception and dissemination of information, which in turn have reciprocal effects on those attitudes. The current paper aims at understanding how the diffusion of information and attitudes in networ...

Nagaland, the 16th state of India in order of statehood, is situated between 25° 6′ and 27° 4′ latitude north and between 93o 20′ E and 95o 15′ E longitude of equator in the North Eastern part of the India. Endowed with varied topography, soil and agro climatic conditions it is known for its potentiality to grow all most all kinds of horticultural crops. Pineapple being grown since long organic...

Recently climate change issues have come to the forefront. Climate change is a global challenge. It is a threat to social and economic stability and sustainable human existence. There is no doubt that climate change affects the fundamental requirement for health – clean air, safe drinking water, sufficient green food and secured shelter. Many measures have to be planned for and taken into accou...

One of the most important tasks information systems executives face is making sense of emerging opportunities for organizational innovation through information technology. However, the parlance of information systems practitioners yields a variety of metaphors suggesting that this crucial task is a perilous one, in which success is far from assured. This paper reports on an interpretive study o...

T he relationship of action to attitude change has been a central and recurrent theme ill my work ever since my doctoral dissertation (Kelman, 1953). I have written several theoretical papers on this issue over the years (Kelman, 1¢2a, 1974a, I974b, 1978), and during the 19605 several colleagues and I were engaged in an experimental pflJgram on the relationship of discrepant action and attitude...
