despite providing robustness, high-gain observers impose a peaking phenomenon, which may cause instability, on the system states. in this paper, an adaptive saturation is proposed to attenuate the undesirable mentioned phenomenon in high-gain observers. a real-valued and differentiable sigmoid function is considered as the saturating element whose parameters (height and slope) are adaptively tu...

Seagrass detritus can attract numerous invertebrates as it provides food and substrate within the meadow or in adjacent environments. Nonetheless, several factors could modify invertebrate response to this habitat. In study, we tested if epifaunal colonisation of Zostera noltei was related availability rather than whether colonising assemblages were similar according structural complexity. Litt...

The paper proposes a method for observer design for a class of nonlinear systems. We decompose the system using a weaker concept than the relative degree. We provide sufficient conditions for global asymptotic stability of the error dynamics. The observer design is carried out by means of a change of coordinates combined with a high gain technique. In particular, our approach results in an obse...

One of the stated aims of the state-funded school system in Scotland is to help develop global citizens for the future. This paper argues that Global Citizenship must recognize the continued widespread adherence to religion, acknowledge religious diversity and the challenges faced by religious minorities to ensure a more comprehensive education in cultural identity, human rights, diversity and ...

Increasing global urbanization has led to the growth of urban slums, challenged by fragmented and inefficient health care services. This is evident in Kibera (Nairobi, Kenya), one of Africa’s largest slums. With an estimated average population of 270,000, it is serviced by over 100 clinics [1], operating in isolation of one another. The Kibera Medical Record Initiative (KMRI) aims to develop an...
