Surgical simulation applications have been largely limited to the acquisition and assessment of technical skills. Current teaching and assessment of surgical judgment is nonsystematic and prone to error. Interest in methods to enhance the acquisition and assessment of knowledge-based (judgment) skills for intraoperative decision making has led to the application of cognitive task analysis (CTA)...

was honored and excited when Alfred Abuhamad, MD, president of the American Institute of Ultrasound in Medicine (AIUM), asked me to head a task force to educate AIUM members and nonmembers about when and how to do sonography for conditions where other imaging modalities are likely to be considered instead. As an imaging modality, sonography is safe, effective, and affordable compared with other...

Demand Forecasting is an essential process for any firm whether it is a supplier, manufacturer or retailer. A large number of research works about time series forecast techniques exists in the literature, and there are many time series forecasting tools. In many cases, however, selecting the best time series forecasting model for each time series to be dealt with is still a complex problem. In ...

The analysis of time series databases is very important in the area of medicine. Most of the approaches that address this problem are based on numerical algorithms that calculate distances, clusters, index trees, etc. However, a symbolic rather than numerical analysis is sometimes needed to search for the characteristics of the time series. Symbolic information helps users to efficiently analys...

Disruptive technologies and novel aircraft generations represent a potential approach to address the ambitious emission reduction goals in aviation. However, introduction of innovative concepts is time-consuming process, which might not necessarily yield an optimal design for given flight mission within defined time frame. In order need structured more exhaustive search concept generations, Adv...

In text books as well as in the business literature, market basket analysis is often promoted as a means to obtain product associations to base a retailer’s promotion strategy on. They argue that associated products with a high lift/interest can be promoted effectively by only discounting just one of the two products. Implicitly, they argue that market basket analysis automatically identifies c...

Most subjective probability aggregation procedures use a single probability judgment from each expert, even though it is common for experts studying real problems to update their probability estimates over time. This paper advances into unexplored areas of probability aggregation by considering a dynamic context in which experts can update their beliefs at random intervals. The updates occur ve...
