This paper presents a simple unknown input estimation technique using generalized matrix inverse. The full order observer constructed by g-inverse is extended and implemented for this purpose. The necessary and sufficient condition has been introduced for existence of such an estimator. The proposed method is illustrated by numerical example (Two loop autopilot in pitch plane) and the MATLAB si...

INTRODUCTION Medical education researchers increasingly collaborate in international teams, collecting data in different languages and from different parts of the world, and then disseminating them in English-language journals. Although this requires an ever-present need to translate, it often occurs uncritically. With this paper we aim to enhance researchers' awareness and reflexivity regardin...

Researchers have always recognised the importance of disseminating the findings of their work, however, recently the need to proactively plan and drive the impact of those findings on the wider society has become a necessity. Firstly, this is because funders require evidence of return from investment and secondly and crucially because national research assessments are becoming powerful determin...

One of the most striking developments across the social sciences in the past decade has been the growth of research methods using visual materials. It is often suggested that this growth is somehow related to the increasing importance of visual images in contemporary social and cultural practice. However, the form of the relationship between 'visual research methods' and 'contemporary visual cu...
