Interpretation of symbols, as well as understanding the particulate nature of matter and spatial structures, are essential skills students need for solving problems in chemistry. However, model perception and understanding the spatial structure of organic molecules has been a source of difficulty for many chemistry students. The research objective was to investigate the effect of using virtual ...

Traditionally, abrasive finishing process focus on producing excellent surface finish on regular form shapes. Ever increasing demands in freeform features in aerospace, energy and medicine industry requires abrasive finishing technology not only provides excellent surface finish but also is capable to correct the errors on freeform surfaces. The paper presents current development of corrective ...

The rapid development of choice modelling procedures, especially using Stated Preference data, over the past twenty years, has created an opportunity for an imbalance between the models and the data used for construction of the models. This paper examines this imbalance and stresses the need for more attention to be paid to the needs of the respondent when collecting data for choice modelling. ...

We provide a characterization of selection correspondences in two-person exchange economies that can be core rationalized in the sense that there exists a preference profile with some standard properties that generates the observed choices as the set of core elements of the economy for any given initial endowment vector. The approach followed in this paper deviates from the standard rational ch...

Using case–based learning when teaching enterprise modeling could provide the realism needed for students to understand the complexity of a real modeling situation. This realism could be enhanced further by having case material presented in the form similar to what is found in modeling practice, such as recorded interviews and internal and external documents. However, creating this kind of mate...
