We asked whether the large variability in odor imaging ability is underlain by interindividual differences in the processing of smells and emotion. Olfactory imaging ability, anhedonia level, and odor perception were measured in 40 subjects, using the Vividness of Olfactory Imagery Questionnaire (VOIQ), the Physical Anhedonia Scale, and the European Test of Olfactory Capabilities. "Good" olfact...

In model-driven software engineering, model transformations are used for the specification of model changes. Similar to programs also model transformations can exhibit bad smells which indicate possible weaknesses. In this paper, we address bad smells which can negatively affect the performance of the application of model transformations, particularly, model transformations defined in Henshin. ...

Some software packages offer the user soft advice: recommendations that are intended to help the user create high quality artifacts, but which may turn out to be bad advice. It is left to the user to determine whether the soft advice really will improve quality, and to decide whether or not to adopt it. Visualizations can help the user in making this decision, but we believe that conventional v...

In philosophical discussions of the secondary qualities, color has taken center stage. Smells, tastes, sounds, and feels have been treated, by and large, as mere accessories to colors. We are, as it is said, visual creatures. This, at least, has been the working assumption in the philosophy of perception and in those metaphysical discussions about the nature of the secondary qualities. The resu...

The Software Product Lines (SPL) paradigm has arisen for taking advantage of existing common aspects between different products, while also considering product-specific features. The architecture of a SPL comprises a model that will result in product architectures, and may include solutions leading to bad (architectural) design. One way to assess such design decisions is through the identificat...

Bad smells affect maintainability and performance of model-to-model transformations. A number of studies have defined a set of transformation bad smells, and proposed techniques to recognize and —according to their complexity— fix them in a (semi-)automated way. In education, it is necessary to make students aware of this subject and provide them with guidelines to improve the quality of their ...

Refactoring improves the design of software and makes it easier to maintain by eliminating code smells. As manual refactoring is often error-prone and time-consuming, automated refactoring is considered a better choice. Refactoring tools are available in almost all major object oriented programming languages like java, C++, C# etc and provide varying degree of automation. The problem with these...

Large and complex software systems are confronted with continuous changes during all stages in their life comprising development, maintenance, migration, and retirement. On the one side these changes are mandatory to guarantee the success of a software system but on the other side changes affect the architecture and design of a software system. Therefore, a continuous observation and analysis o...

Olfaction consists of a set of transforms from a physical space of odorant molecules, through a neural space of information processing, and into a perceptual space of smell. Elucidating the rules governing these transforms depends on establishing valid metrics for each of the three spaces. Here we first briefly review the perceptual and neural spaces, and then concentrate on the physical space ...
