The Anglo-Zulu war of 1879 was perhaps subjected to much controversy as a result of the epic Zulu victory at the battle of Isandlwana. Lord Chelmsford, the General Officer commanding the invasion force during the war, sustained severe criticism from both journalists and parliament following his actions and conduct at Isandlwana. In 1939 and on the sixtieth anniversary of the battle, Major, the Hon Gerald French, wrote a controversial but riveting book titled'Lord Chelmsford and the Zulu War,' is based on defending both Lord Chelmsford's actions and reputation. The foreword to the book was written by General Sir Bindon Blood who served under Chelmsford in India and a devoted admirer.French however, had fallen into the error of selective inaccurate source material and false reports that were, at the time, specifically designed to shield Lord Chelmsford from the Isandlwana debacle and conveniently lay such blame on the shoulders of Colonel Anthony Durnford, Royal Engineers, who was present at Isandlwana. For example, in looking for such evidence, French deliberately altered a map that showed the true disposition of the imperial defence line at the battle in order for readers to reach the conclusion that the primary course of the defeat was the retreat of the Natal Native Contingent , that opened a gap in the defence , thus allowing an unopposed Zulu advance.The book is nevertheless a comprehensive and detailed coverage of the Anglo Zulu war from the initial invasion to the final battle of Ulundi some months later, and has been used extensively as bibliography by authors when addressing the subject of the Anglo-Zulu war. This book is highly recommended for those with a historical interest of the events of 1879 and the demise of the Zulu nation.
This book examines the role of the Scots in the development of Canadian sport. The evidence from the wide range of primary and secondary sources cited by the author proves that the Scottish contribution was significant.
`Electric energy must be treated as a commodity which can be bought, sold, and traded, taking into account its time- and space-varying values and costs.` Spot Pricing of Electricity, Schweppe et al, 1988. Computational Auction Mechanisms for Restructured Power Industry Operation outlines the application of auction methods for all aspects of power system operation, primarily for a competitive environment. A complete description of the industry structure as well as the various markets now being formed is given. A thorough introduction to auction basics is included to explain how auctions have grown in other industries. Auction methods are compared to classical techniques for power system analysis, operations, and planning. The traditional applications of economic dispatch, optimal power flow and unit commitment are compared to auction mechanisms. Algorithms for auctions using linearized power flow equations, DC power flow equations, and AC power flow equations are included. The bundling of supportive services, known as ancillary services within the United States, is discussed. Extensions to the basic auction algorithms for inclusion of supportive services as well as algorithms for scheduling and bidding on generation for GENCOs or independent power producers are presented. Algorithms for scheduling and contracting with customers are also presented for energy service companies. An introduction to the various commodity and financial market products includes the use of futures and options for GENCOs. The material is useful for students performing research on the new business environment based on competition. Regulators will find information on initial methods of designing and evaluating market systems, and power exchange and financial analysts will find information on the interdependence of markets and power system-based techniques for risk management. This information compares the new business environment solutions with old business environment solutions. Computational Auction Mechanisms for Restructured Power Industry Operation provides a first introduction to how electricity will be traded as a commodity in the future.
This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.
