    A system consists of a set of interrelated components which are dependent on another. A system is fundamentally altered, therefore, if a component joins or leaves it. A purposeful activity is also central to the concept of the system. The author looks at the attributes of systems and the relationship between theory and practice.<> View full abstract»

    With the strong and persistent upward trend in the volume of road traffic, many major roads in urban areas, estuarial river crossings, national trunk roads and motorways are experiencing a rapid increase in congestion. Toll roads are one answer but it is difficult to collect tolls without more queues generating more delays. Automated collection of tolls is looked at including the problems of lack ...

    Despite the widespread success of the PWR, the design has certain disadvantages, notably in the complex demands placed on the reactor's safety systems. There is a continuing interest among reactor designers in the development of the safe integral reactor (SIR). The author looks at the design of the SIR, which is an integral PWR, reactivity control, stability, loss-of-coolant accident and decay hea... View full abstract»

    The author looks at the Earth from space, at the fragility of its climate, and at the protection of the climate by carefully watching and monitoring from space. A model of the climate is constructed and how the EM radiation influences the planet is discussed. Clouds, radiation and energy balance are looked at from space and satellite missions which can be used to monitor the long-term trends are p... View full abstract»
