In component-based development, object-oriented modelling notations such as UML are being proposed as a way of providing richer specifications of components. Much more so than in bespoke software development, this requires a high level of precision coupled with sufficient expressive power. Expressive power is delivered by adding textual annotations, such as invariants, pre & post conditions, to...

Effective workflows are essential components in the digitization of biodiversity specimen collections. To date, no comprehensive, community-vetted workflows have been published for digitizing flat sheets and packets of plants, algae, and fungi, even though latest estimates suggest that only 33% of herbarium specimens have been digitally transcribed, 54% of herbaria use a specimen database, and ...

Working memory, or the ability to maintain and manipulate information such that it can be used to guide behavior, is known to be severely capacity limited, in most circumstances, to about 3-4 objects. Both infants and adults have the ability to surpass these limits by encoding tobe-remembered items in groups or collections, exploiting statistical regularities or conceptual information to devise...

To date, the vast majority of recommender systems research has addressed the problem of recommending individual items that the user will like. Recommending collections of items rather than individual items is an important open space of research in the recommender systems community. In this paper, we present a comprehensive framework for describing and evaluating collections of items. This frame...

Tropical forage genetic resources are essential material for the development of adapted pasture crops. Collection, conservation and characterization of these resources are needed to preserve them for future generations. Collections were made after 1970 by CIAT, CSIRO and ILRI. The current status of these collections and present conservation methods are reviewed. Genetic diversity has been asses...

Software libraries have long been an integral element of software development. Recent advances in areas such as software product lines and extensibility mechanisms have focused renewed attention on collections, particularly heterogeneous collections, of software artifacts. The contribution of this paper is to propose a model for a software library. Our work creates a framework that is abstract ...
