titlan in the Valley of Mexico, that Aztec city was the capital of a far-flung tributary empire. The emperor Motecuhzoma sat atop a complex social and political hierarchy, and the Aztec populace owed allegiance and tribute to nobles at several levels. Below the emperor were the kings of subject city-states. The Aztec dominion employed a policy of indirect rule, and imperial authorities supporte...

This paper presents the 2005 MIRACLE’s team participation in the ImageCLEFmed task of ImageCLEF 2005. This task certainly requires the use of image retrieval techniques and therefore it is mainly aimed at image analysis research groups. Although our areas of expertise don’t include image analysis research, we decided to make the effort to participate in this task to promote and encourage multid...

In reconfigurable systems, reconfiguration latency has a significant impact on the system performance. In this work, a temporal partitioning algorithm is presented to partition data flow graphs for reconfigurable computing systems. Life-time of a node in a data flow graph represents the number of times it executes during the application run. A new factor, called residing eligibility, inspired f...

We consider the non-linear properties and boundaries in the three forms of sharing, gift, and reselling economy. We decode the economic rationality and marketplace mechanisms in today’s ever booming sharing/gifting/reselling networks. We contribute to the fundamental economics literature by decomposing a merchandise into two parts: the ownership good and the detached good. The ownership good ca...

The ImageCLEF task of CLEF has a main goal in the retrieval of images from multi–lingual collections. The 2003 imageCLEF saw no group using the visual information of images, which is inherently language independent. The query topics of the St. Andrews collection are defined in a way that makes visual retrieval hard as visual similarity plays a marginal role whereas semantics and background know...

The study of creativity in design has tended to emphasize its value and location in the individual designer as part of a statistically outlying population rather than as a normal characteristic of an entire population. Theories of creativity have generally stressed either its mysterious, gift-like qualities to an individual or as a constructed relationship between consumer and designer. This ar...

We construct a constant-round resettably-sound zero-knowledge argument of knowledge based on black-box use of any one-way function. Resettable-soundness was introduced by Barak, Goldreich, Goldwasser and Lindell [FOCS 01] and is a strengthening of the soundness requirement in interactive proofs demanding that soundness should hold even if the malicious prover is allowed to “reset” and “restart”...

In the gift exchange game there are n players and n wrapped gifts. When a player’s number is called, that person can either choose one of the remaining wrapped gifts, or can “steal” a gift from someone who has already unwrapped it, subject to the restriction that no gift can be stolen more than a total of σ times. The problem is to determine the number of ways that the game can be played out, f...

A study is reported in which participants gained experience with deductive reasoning and learned how to complete logic grid puzzles through a computerized tutorial. The names included in the clues and content of the puzzle varied by condition. The names present throughout the learning experience were either the participant’s own name, and the names of two friends; the names of characters from a...
