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...

This paper describes the design of an observer for use in a distributed parameter control system which is used to regulate the surface temperature profile of a tool or die being manufactured by sprayforming. The observer design is complicated by the time varying obscuration of the surface from the sensor caused by the equipment performing the spraying. Three potential observer designs are prese...

The use of IT to support global processes has opened up opportunities for some countries to source skills from other countries often located in very different parts of the world. This study investigates the relationship between ICT Capacity and Skills and their effects on Economic Development from 2001 to 2005 for each of the 183 countries that are members of the United Nations. Following an an...
