Conceptual Design is one of the few areas of Engineering Design where computers have yet to make an impact. With the development of Knowledge Based Systems it is now possible to rectify this situation. This publication deals with the use of Knowledge Based Systems (KBS) as tools for conceptual design. Included are neglected aspects such as evaluation and user needs. Practical Knowledge Based Systems in Conceptual Design is based on the authors' experience of developing KBS for use in civil engineering, an area of industrial application which is recognised as being one of great potential. The methodology has been tried and tested by designers. Examples of systems which have been developed to solve specific design problems are included.

Rising above the northwestern part of the Cascades is the magnificent bulk of Mount Baker - "Koma Kulshan" ("the steep white mountain" to the early Nooksack Indians). Long a focal point of human interest, this slumbering volcano has been seen in many different lights--as a sacred object, a great challenge, a stimulus for creativity, a playground. Yet, despite all human actions and aspirations over the years, the mountain retains its majesty, power and mystery. This is the story of man and Mount Baker, complete with engaging first hand tales and a wealth of rare photos.

Wilderness in National Parks casts light on the complicated relationship between the National Park Service and its policy goals of wilderness preservation and recreation. By examining the overlapping and sometimes contradictory responsibilities of the park service and the national wilderness preservation system, John C. Miles finds the National Park Service still struggling to deal with an idea that lies at the core of its mission and yet complicates that mission, nearly one hundred years into its existence. The National Park Service's ambivalence about wilderness is traced from its beginning to the turn of the twenty-first century. The Service is charged with managing more wilderness acreage than any government agency in the world and, in its early years, frequently favored development over preservation. The public has perceived national parks as permanently protected wilderness resources, but in reality this public confidence rests on shaky ground. Miles shows how changing conceptions of wilderness affected park management over the years, with a focus on the tension between the goals of providing recreational spaces for the American people and leaving lands pristine and undeveloped for future generations.
