If students of world politics can be reasonably accused of ignoring the Troubles in Northern Ireland—in part because they seemed to have little to do with the larger East-West confrontation and partly because they were so obviously about something distinctly national in character—then by the same token specialists on Northern Ireland can justly be accused of a certain intellectual parochialism and of failing to situate the long war within a broader global perspective. The quite unexpected outbreak of peace however only emphasizes the need for a wider understanding of the rise and fall of the Northern Irish conflict. This article explores the relationship between the partial resolution of the Irish Question—as expressed in the Good Friday Agreement of 1998—and the changing character of the European landscape. Its central thesis is that while there were many reasons for the outbreak of peace in the 1990s, including war weariness, it is difficult to understand what happened without situating it in a larger European framework and the new definition of sovereignty to which the EU has given birth.
Conventional cruise control systems fulfil the function of automatic speed control. A desired speed is selected by the driver, and a control system operates on the throttle to maintain this desired speed. When traffic density is moderate or high, the driver is faced with having to adjust the set speed regularly in order to maintain a comfortable distance from preceding vehicles and will frequently have to brake, disengaging the cruise control. Thus conventional cruise control can become a source of irritation when used in moderate or heavy traffic. If a distance sensor is added to a conventional cruise control system, then it is possible to add distance keeping to the basic speed control function. This forms the basis for adaptive cruise control, which can be further improved if a limited authority braking system is incorporated. Use can then be made of both throttle and brake actuators to control the distance and relative velocities between a vehicle and a preceding target vehicle.
