Many crimes can happen every day in a major city, and figuring out which ones are committed by the same individual or group is an important and difficult data mining challenge. To do this, we propose a pattern detection algorithm called Series Finder, that grows a pattern of discovered crimes from within a database, starting from a “seed” of a few crimes. Series Finder incorporates both the com...

Each of two players, by turns, rolls a dice several times accumulating the successive scores until he decides to stop, or he rolls an ace. When stopping, the accumulated turn score is added to the player account and the dice is given to his opponent. If he rolls an ace, the dice is given to the opponent without adding any point. In this paper we formulate this game in the framework of competiti...

Question answering involves developing methods to extract useful information from large collections of documents. This is done with specialised search engines such as Answer Finder. The aim of Answer Finder is to provide an answer to a question rather than a page listing related documents that may contain the correct answer. So, a question such as"How tall is the Eiffel Tower"would simply retur...

The infrared range finder for a mobile robot has the advantages of the low sensing cost and detecting all objects in front of the mobile robot after sensing. However, it has some non-linear bias errors, the measurement data represents the Gaussian distribution, and the variance of measurement error increases in proportion to distance. This paper set a goal to analyze the characteristics of an i...

Laser range finders are a vital component of high precision targeting engagements. The precise and accurate range-to-target information is an essential variable in the fire control solution of today’s sophisticated weapons. This range information is readily provided by the laser range finder, however, current fielded laser range finders are bulky, heavy, difficult to mount onto weapons, eye haz...
