Smells Like the Real Thing

چکیده
Whether bulbous, Roman, or pug, the nose gets all the credit. But the actual star of smell is an unassuming patch of tissue, several centimeters square, tucked up inside each nasal cavity. After a whiff of a peach or a lilac, this tissue captures the volatile chemicals traveling into each nostril. The chemicals bind to receptors on the tissue's millions of neurons, the neurons relay the information to the brain, and voilà—you know that the peach is ripe and the lilacs are in bloom.

Investigating the Role of Code Smells in Preventive Maintenance
The quest for improving the software quality has given rise to various studies which focus on the enhancement of the quality of software through various processes. Code smells, which are indicators of the software quality have not been put to an extensive study for as to determine their role in the prediction of defects in the software. This study aims to investigate the role of code smells in ...
متن کاملChallenges in the Evolution of Metamodels: Smells and Anti-Patterns of a Historically-Grown Metamodel
In model-driven engineering, modeling languages are developed to serve as basis for system design, simulation and code generation. Like any software artifact, modeling languages evolve over time. If, however, the metamodel that defines the language is badly designed, the effort needed for its maintenance is unnecessarily increased. In this paper, we present bad smells and anti-patterns that we ...
متن کاملIndividual differences in odor imaging ability reflect differences in olfactory and emotional perception.
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...
متن کاملUtilising Code Smells to Detect Quality Problems in TTCN-3 Test Suites
Today, test suites of several ten thousand lines of code are specified using the Testing and Test Control Notation (TTCN-3). Experience shows that the resulting test suites suffer from quality problems with respect to internal quality aspects like usability, maintainability, or reusability. Therefore, a quality assessment of TTCN-3 test suites is desirable. A powerful approach to detect quality...
متن کاملTowards a Catalog of Spreadsheet Smells
Spreadsheets are considered to be the most widely used programming language in the world, and reports have shown that 90% of real-world spreadsheets contain errors. In this work, we try to identify spreadsheet smells, a concept adapted from software, which consists of a surface indication that usually corresponds to a deeper problem. Our smells have been integrated in a tool, and were computed ...
