Here we report on the gas-phase interactions between protonated enantiopure amino acids (L- and D-enantiomers of Met, Phe, and Trp) and chiral target gases [(R)- and (S)-2-butanol, and (S)-1-phenylethanol] in 0.1-10.0 eV low-energy collisions. Two major processes are seen to occur over this collision energy regime, collision-induced dissociation and ion-molecule complex formation. Both processe...

Action rules describe possible transitions of objects from one state to another with respect to a distinguished attribute. Previous research on action rule discovery usually requires the extraction of classification rules before constructing any action rule. In this paper, we present a new algorithm that discovers action rules directly from a decision system. It is a bottom-up strategy which ha...

In Eiffel, the notion of agent makes it possible to describe and manipulate computation parts (i.e. operations) like ordinary data. Operations may be partially described, may be passed as ordinary data and may have their execution delayed. Agents are very convenient for many purposes, such as going through data structures and implementing call-backs in graphical libraries. Although they can be ...

We present GREAT (GRaphical tool for rules Editing and AudiTing), an approach and a tool for graphical business rules management that we designed and developed. This collaborative Web-based application with rich user interface enables easy creation and editing of business rules. Relevant features are (1) the ability to define templates of business rules with various levels of granularity and of...

GENGED is a generic graphical editor supporting the graphical definition of visual languages. Given an alphabet and rules of a specific visual language GENGED generates a syntax-directed graphical editor for this language. GENGED as well as each visual language defined using GENGED is based on algebraic graph grammars. A sentence is given by a graphical structure consisting of a logical (abstra...

A metagraph is a graph-theoretic construct that has been shown to be a useful basis for graphical visualization and algebraic analysis of DSS resources such as models, data and rules. In this paper, we describe the structure and use of a metagraph-based DSS analysis workbench that can also be used as a front-end to an existing DSS for activities such as database design and model analysis.
