Coordinate measuring systems (CMSs) determine dimensional (length-based) characteristics of mechanical parts by analyzing 3-dimensional point data acquired on part surfaces. Data analysis software can contribute significantly to the total measurement error of a CMS. Factors affecting software performance include the choice of analysis method, the quality of software implementation, and characte...

Heterogeneous systems comprising sets of inherent subsystems are challenging to integrate. In particular, testing for interoperability and conformance is a challenge. Furthermore, the complexities of such systems amplify traditional testing challenges. We explore (1) which techniques are frequently discussed in literature in context of heterogeneous system testing that practitioners use to test...

Sentiment is expressed differently in different domains. For instance, words which are used in both domains can change their polarity. In this article, we present a study on these multi-polarity words. We first show that these multi-polarity words are actually used by automatic opinion classifiers and affect their performances: the classification performance improves if the multi-polarity words...

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) recently completed the second phase of its Low Global Warming Potential Alternative Refrigerants Evaluation Program (Low-GWP AREP). This industry-wide cooperative research program identified and evaluated promising alternative refrigerants over the past five years. Seventeen low-GWP refrigerants were tested during the second phas...

In this exploratory focus group study, we investigate which possible characteristics could be considered when selecting exercises for learners and how humans adapt exercise selection to learner personality and performance, so that an Intelligent Tutoring System (ITS) can tailor exercise difficulty to these characteristics. In six focus groups, we had discussed which characteristics of the learn...

Automation in generation of architectural feedback from performance indexes like probability distributions, mean values and variances has been of interest to the researchers from last decade. It is well established that due to the complexity in interpreting the performance indices obtained from performance analysis of software architecture and short time to the market, an automated approach is ...

Fatigue at the wheel has been strongly related to car accidents. Traditionally, this phenomenon has been studied in laboratory conditions by means of performance testing. Here, we aimed to improve road safety assessing driver fatigue at the wheel in real scenarios. For this purpose, we have built BioTracker R ©: a flexible non invasive platform. A smartphone and a microcontroller unit are the c...
