The effect of temperature change on dynamic performances of an industrial robot with six axes of freedom is studied in this paper. In general, the strain and stress are produced not only by the external exciting force, but also by temperature change. The strain energy that is caused by temperatureThis paper describes how the temperature variation effects the dynamic performance of an indu...

In this paper we describe corporate memory which can support multiple knowledge acquisition, organization and maintenance tools. Memory holds and manages documents and related information and knowledge processed and created by such tools. Tools can work with several types of data such as documents, data in relational database and semantic data. Such diversity of information is needed due to dif...

Although constraints are useful to express semantic restrictions on object structures, Java provides little support for their implementation and evaluation. We argue that constraints should be specified explicitly, and propose a set of design patterns for the representation of constraints on JavaBeans. Object-oriented reflection is used to evaluate these constraints at run-time. We show how thi...

In previous studies, causal contingencies have been suggested to play an important role in causality judgments. However, little is known about how children might use causal contingencies to inform their judgments of causality, especially under uncertainty. In the current study, we found that young children are sensitive to both conditional and unconditional causal contingencies. Furthermore, ch...

An object learning system for image understanding is proposed in this paper. The knowledge acquisition system is designed as a supervised learning task. Therefore, the role of the user as teacher of the system is emphasized, which allows to obtain the object description as well as to select the best recognition strategy for each specific object. An object description is acquired by considering ...

Microstructures of Learning: Novel methods and approaches for assessing structural and functional changes underlying knowledge acquisition in the brain The HuMeNS (Humanities, Medicine, Natural science, Social sciences) Advanced Study Group at Pufendorf Institute, Lund University is conducting an interdisciplinary research program involving collaboration between linguistics, neuroscientists, ph...

This article presents a conceptual analysis of collaboration scripts used in face-to-face and computer-mediated collaborative learning. Collaboration scripts are scaffolds that aim to improve collaboration through structuring the interactive processes between two or more learning partners. Collaboration scripts consist of at least five components: (a) learning objectives, (b) type of activities...

Evaluation of knowledge acquisition (KA) technology is difficult because of the costs of using human expertise in experimental studies. An analysis of the types of errors a human expert makes in building a knowledge-based system (KBS) has been developed which suggests that a simulation of the key factors in building a KBS is possible. A demonstration KA simulation has been implemented for one K...

A knowledge acquisition study in the domain of tall building design was conducted. Domain experts, five structural engineers and one architect, were interviewed. The experts were asked a set of questions divided into design process and design content questions, and asked to simulate a design scenario. The experts were also shown, and asked to critique, a prototype implementation of a design gra...
