We consider the problem of locating a light coin out of a set containing n coins, n ? 1 of which have the same weight. The weighing device is a balance with r 2 pans and, when r equally sized subset of coins are weighted, it indicates the eventual subset containing the light coin. We give an algorithm to nd the counterfeit coin that requires the minimum possible average number of weighings. All...

Undetected hip dysplasia can lead to significant morbidity. We report a case of development hip dysplasia, which was diagnosed incidentally following radiographic investigation for an ingested coin. CASE REPORT A two-year-old girl was brought to the emergency department following the ingestion of a one pence coin. A thoraco-abdominal radiograph demonstrated the presence of a coin within the fir...

Experience Management (EM) is an area that is increasingly gaining importance. Its roots lie in Experimental Software Engineering, in Artificial Intelligence, and in Knowledge Management. In this paper, we will present the Corporate Information Network (CoIN) initiative, which is responsible for the build-up and operation of Experience Management at IESE. Three aspects of CoIN are detailed: (1)...

This paper discusses the current status and issues regarding Web-Coin, a newly emerging e-payment form in China. Web-coin has been well accepted in China due to its efficient and convenient payment features. The paper also discusses some ongoing controversial issues with Web-Coin, including regulation problems and the potential risks. This paper is intended to be a valuable reference and implic...

We’ll use a statistical model of the problem to motivate a prediction strategy, as well as to evaluate the quality of various strategies. In this model, the outcome of the coin toss is random; it is “heads” with some probability, say, p; and it is “tails” with the remaining probability 1 − p. We’ll encode “heads” by 1, and “tails” by 0, so the outcome is a random variable Y . The number p is a ...
