An exciting and heart-pounding look at one of Western Canada's most adventurous individuals, known as a pioneer pilot of the heli-ski industry and as the first mountain-rescue pilot in the Canadian National Parks system. Jim Davies is an icon of competence and courage as the first heli-skiing pilot in Canada. But it is his groundbreaking work as a helicopter rescue pilot for Parks Canada that made him a legend to all who worked with him. His stellar career as a pilot overshadowed his other talents as a ski racer and artist. Jim received several awards for his work in mountain rescue, including the Helicopter Association International - Pilot Safety Award of Excellence, the Alberta Achievement Award for excellence in helicopter flying, the Summit of Excellence Award at the Banff Film and Book Festival, and the Robert E. Trimble Memorial Award for "distinguished performance in helicopter mountain flying." He is now retired and living in Banff, pursuing his love of painting and photography.
The book contains the papers presented at the IAG Symposium on Vertical Reference Systems held in Cartagena, Colombia, in February 2001. It covers the status report of existing height reference systems and the latest steps towards the establishment of a unified vertical reference system. Classical and modern height determination techniques are included as well as the determination of height reference surfaces like sea level and geoid. Emphasis is also given to the variations of the reference systems with time, i.e., sea level changes and geodynamic deformations.
In plain, uncomplicated language, and using detailed examples to explain the key concepts, models, and algorithms in vertical search ranking, Relevance Ranking for Vertical Search Engines teaches readers how to manipulate ranking algorithms to achieve better results in real-world applications. This reference book for professionals covers concepts and theories from the fundamental to the advanced, such as relevance, query intention, location-based relevance ranking, and cross-property ranking. It covers the most recent developments in vertical search ranking applications, such as freshness-based relevance theory for new search applications, location-based relevance theory for local search applications, and cross-property ranking theory for applications involving multiple verticals. - Foreword by Ron Brachman, Chief Scientist and Head, Yahoo! Labs - Introduces ranking algorithms and teaches readers how to manipulate ranking algorithms for the best results - Covers concepts and theories from the fundamental to the advanced - Discusses the state of the art: development of theories and practices in vertical search ranking applications - Includes detailed examples, case studies and real-world situations
