I-X is a research programme intended to create a well-founded approach to allow humans and computer systems to cooperate in the creation or modification of some product such as a design, physical entity or plan – i.e. it supports mixedinitiative synthesis tasks. The I-X mixed-initiative approach involves the use of shared models for task-orientated communication between human and computer agent...

Tailoring advice to a user means finding a plan by which she can reach her goal, and supplying the missing knowledge that she needs to successfully execute the plan. The paper presents a method to determine the kind and amount of this missing knowledge for an already generated domain plan. We show that both a user’s knowledge and his capabilities to perform actions must be taken into account wh...

I-X is a research programme with a number of different aspects intended to create a well-founded approach to allow humans and computer systems to cooperate in the creation or modification of some product such as a design, physical entity or plan i.e. it supports cooperative synthesis tasks. The IX approach involves the use of shared models for task-directed cooperation between human and compute...

Transformation and regeneration is routine for many crop plants. A genetically engineered tomato with a longer shelf life at full ripeness was introduced in the United States in 1994, and other soon-to-be-released products, both foods and fibers, incorporate genes for resistance to pests, diseases, and environmentally benign herbicides. Other possibilities are altered plant fats and oils, methi...

Existing software architecture research has focused on static architectures, where the system architecture is not expected to change during system execution. We argue that the architectures of many systems, especially long running or mission critical systems, evolve during execution, and thus cannot be accurately modeled and analyzed using static architectures. To overcome these problems, we pr...

This essay is concerned about how to evaluate positive theories on Latin American development. Its content is nested in a broader discussion on theoretical decay and theoretical progress by using Imre Lakatos’ approach of sophisticated falsificationism. The main argument states that theory driven research on Latin American development provides further evidence to the assumption that methodologi...
