A critical comparison on attitude estimation: from gaussian approximate filters to coordinate-free dual optimal control

This paper conveys attitude and rate estimation without rate sensors by performing a critical comparison, validated by extensive simulations. The two dominant approaches to facilitate attitude estimation are based on stochastic and set-membership reasoning. The first one mostly utilizes the commonly known Gaussian-approximate filters, namely the EKF and UKF. Although more conservative, the latter seems to be more promising as it considers the inherent geometric characteristics of the underline compact state space and accounts—from first principles—for large model errors. The set-theoretic approach from a control point of view is addressed, and it is shown that it can overcome reported deficiencies of the Bayesian architectures related to this problem, leading to coordinate-free optimal filters

Civics and citizenship education: What have we learned and what does it mean for the future of Australian democracy?

The ambitious project to nationalise the Australian Curriculum has prompted great interest among policymakers, academics and civics teachers in Australian schools. The government-led citizenship education initiative Discovering Democracy (1997–2007) comprehensively failed to meet its objectives, most prominently the stated goal of developing active citizens. This article has twin objectives: to explore the ways in which government-directed civics education programmes have fallen short; and to argue for a shift in our approaches to civics education, in terms of both content and delivery, drawing on the surplus model, which credits students with unique ideas, knowledge and experiences. We draw upon Justice Citizens, an alternative approach to Civics Education that foregrounds students’ own interests and abilities as central to their development into active citizens as an example of the educational practices that can promote and strengthen active citizenship among school students. From this programme and other research, we discuss four student-centred themes that should inform further civics education curriculum development. </jats:p

Compactness in Banach space theory - selected problems

We list a number of problems in several topics related to compactness in nonseparable Banach spaces. Namely, about the Hilbertian ball in its weak topology, spaces of continuous functions on Eberlein compacta, WCG Banach spaces, Valdivia compacta and Radon-Nikod\'{y}m compacta

Genetic Determinants and Epidemiology of Cystic Fibrosis–Related Diabetes: Results from a British cohort of children and adults

OBJECTIVE—Longer survival of patients with cystic fibrosis has increased the occurrence of cystic fibrosis–related diabetes (CFRD). In this study we documented the incidence of CFRD and evaluated the association between mutations responsible for cystic fibrosis and incident CFRD, while identifying potential risk factors

Building the capacity to solve complex health challenges in Sub-Saharan Africa : CARTA’s multidisciplinary PhD training

Objectives: To develop a curriculum (Joint Advanced Seminars- JAS) that produced PhD fellows who understood that health is an outcome of multiple determinants within complex environments and that approaches from a range of disciplines is required to address health and development within the Consortium for Advanced Research Training in Africa. We sought to attract PhD fellows, supervisors and teaching faculty from a range of disciplines into the program. Methods: Multidisciplinary teams developed the JAS curriculum. CARTA PhD fellowships were open to academics in consortium member institutions, irrespective of primary discipline, interested in doing a PhD in public and population health. Supervisors and JAS faculty were recruited from CARTA institutions. We use routine JAS evaluation data (closed and open ended questions) collected from PhD fellows at every JAS, a survey of one CARTA cohort and an external evaluation of CARTA to assess the impact of the JAS curriculum on learning. Results: We describe our pedagogic approach arguing its centrality to an appreciation of multiple disciplines and illustrate how it promotes working in multidisciplinary ways. CARTA has attracted PhD fellows, supervisors and JAS teaching faculty from across a range of disciplines. Evaluations indicate PhD fellows have a greater appreciation of how disciplines other than their own are important to understand health and its determinants and an appreciation and capacity to employ mixed methods research. Conclusions: In the short-term, we have been effective in promoting an understanding of multidisciplinarity resulting in fellows using methods from beyond their discipline of origin. This curriculum has international application
