Coriolis mass flow meters are one of the most accurate tools to measure the mass flow in the industry. However, two-phase mode (gas-liquid) may cause severe operating difficulties as well as decreasing certitude in measurement. This paper presents a method based on fuzzy systems to correct the error and improve the reliability of these sensors in the presence of two-phase model fluid. Definite ...

This paper starts from the position that belief is primarily quantitative and not categorical, i.e. we generally assume the existence of various degrees of belief. This corresponds to the observation that most human beings experience belief as a matter of degree. We follow the usual convention that such degrees of belief are values in the [0, 1]-interval, including the two extreme cases 0 for “...

Design of feedback is a critical issue of online assessment development within Web-based Learning Systems (WBLSs). In our work we demonstrate the possibilities of tailoring the feedback to the students’ learning style (LS), certitude in response and its correctness. We observe in the experimental studies that these factors have a significant influence on the feedback preferences of students and...

The certitude of death makes reproduction the foundation upon which all life-history strategies are based. Plasticity in the reproductive biology of organisms is an essential adaptive response to the capricious and hazardous environments of earth. In this article, we use data from a breeding colony for laboratory mice to examine the mortality risks of offspring born at the outer boundaries of t...

Shadd Maruna, in his masterpiece, Making Good (Maruna, 2001, 2011) advocates the creation of an institutionalized redemption ritual which would reinforce the offender's own certitude that he or she has indeed desisted successfully, and convince the community and society itself, that he/she has now become a good citizen. Such a ritual , which would preferably be judicial, exists in the French le...

Successful uses of information technologies usually require teams of developers working in concert (rather than individuals working alone); implying that methodological prescriptions for such developers should centre on issues such as communication and co-ordination. Here, it will be argued that the epistemology proffered by the SSM advocates does not provide a practical basis upon which to con...
