The current state of IGN's project on digital cameras, that has begun in 1991, is described. The features of the present prototypes are presented. The results obtained on two surveys in winter and in summer are described and commented. Since these results have convinced IGN's users of the interest of aerial digital data, these cameras will start in 1997 to be used for IGN production purposes.

Relational instance-based learning (RIBL) algorithms offer high prediction capabilities. However, they do not scale up well, specially in domains where there is a time bound for classification. Nearest prototype approaches can alleviate this problem, by summarizing the data set in a reduced set of prototypes. In this paper we present an algorithm to build Relational Nearest Prototype Classifier...

The object-oriented programming language design space consists of class-based and prototype-based languages. Both language families have been shown to posses many advantages but also several disadvantages with respect to software construction. Hybrid languages featuring both prototype-based and class-based mechanisms have been proposed as a solution. Unfortunately these languages not only unify...

considering iran geographical location, water is the most limited factor in agriculture section. therefore, it would be logical to consider water as one of the most significant criteria in selection of cultivation model. the purpose of this study is assigning cultivation pattern based on economic value of water in gotvand township in agronomic year 2008-2009. so it was necessary to computes the...

This paper describes a previously unreported application of virtual environments – the prediction of product aesthetic quality. Successful prediction of aesthetic quality without the production of a physical prototype requires the integration of a number of ‘software’ models: an assembly model representing the manner in which the product is put together; an environment model providing a real wo...

Sharing and organizing content using corporate wikis remains prohibitively costly for most knowledge workers in organizations. This problem has led to low adoption rates, compromising the utility of such tools. To reduce these costs and increase the benefits we introduce two proof-ofconcept prototypes. We characterize the lifecycle of production and consumption of shared knowledge in a communit...

BACKGROUND Adolescents form impressions about the type of peers who drink (i.e., drinker prototypes). The evaluation of, and perceived similarity to these prototypes are related to adolescents' drinking. Peer drinking norms play an important role in the formation of prototypes. We experimentally examined whether manipulation of peer norms changed the evaluation of and perceived similarity to dr...
