Researchers were hoping the dramatic melting of Arctic ice recorded last year may have been exceptional, but the latest evidence suggests that this year's summer melting has been equally dramatic, with some scientists now predicting that the Arctic may be ice-free in the summer in as little as five year's time. While there has been much hand-wringing about the ecological consequences of such de...

The appearance of this book in a cheap edition is to be heartily welcomed and we hope it will be widely read?especially by those misled by earlier reviews into thinking it a violent attack on religion-It is of course nothing of the kind, but sets out to study the psychological mechanisms involved in certain forms of "religious conver-sion" as well as in psychotherapy and in "brain-washing". It ...

A two army conflict made up of repeated battles with inter-battle reinforcements is considered. Each battle modelled via Lanchester’s ‘aimed fire’ model and three reenforcement strategies; constant, linearly quadratically varying (with respect to post-battle troop levels) are investigated. It shown that while a constant strategy will always lead an outright victory simple partitioning the dimen...

In a multi-battle contest, each time a player competes by investing some of her budgets or resources in a component battle to collect a value if winning the battle. There are multiple battles to fight, and the budgets get consumed over time. The final winner in the overall contest is the one who first reaches some amount of total value. Examples include R & D races, sports competition, election...

The paper analyzes and gives a new perspective on how Geospatial Technology can support Battle Command, and more specifically the integration of GIS technology with services architecture concepts. After some general background on desirability and feasibility, the paper will demonstrate how GIS might be used in a services-enabled battlefield. Finally some examples of systems that integrate these...

This paper addresses a new approach to the longstanding problem of interoperating military command and control with combat simulations. There is great potential benefit in such a capability, both for more effective training and as a “what if” capability during military operations. We describe the Battle Management Language, an unambiguous means of describing military operations to people, simul...

A subrecursive rewriting framework for the classical Kirby and Paris hydra battle is introduced. The termination of a natural rewrite system RH for the Hydra battle is shown by using ordinals and additionally by proving an upper bound on the derivation lengths in terms of a fast growing function of ordinal index ε0. It is shown that the RH -derivation lengths cannot be bounded by a fast growing...
