Percutaneous endoscopic gastrostomy (PEG) has become the modality of choice for providing enteral access to patients who require long-term enteral nutrition. Although generally considered safe, PEG tube placement can be associated with many potential complications. This review describes a variety of PEG tube related complications as well as strategies for(More)
A resource typically executes a particular activity on a series of cases. When a resource performs an activity on several cases simultaneously, (quasi sequentially ly or concurrently, this is referred to as batch processing. Given its influence on process performance, batch processing needs to be taken into account when modeling business processes for(More)
Accurately modeling the interarrival times (IAT) is important when constructing a business process simulation model given its influence on process performance metrics such as the average flow time. To this end, the use of real data from information systems is highly relevant as it becomes more readily available. This paper considers event logs, a particular(More)
Process mining mainly focuses on the retrieval of process models from event logs. As these discovery algorithms make assumptions, performance analyses based on these models can present a biased view. In literature, algorithm-agnostic process metrics have been introduced. Given the critical importance of resources in the light of continuous process(More)
In 1909 Jackson presented his tracheotomy technique to the Eastern Section of the American Laryngological, Rhinological and Otological Society. [1] His technique would become the foundation of the tracheostomy, a procedure that would ultimately become widely utilized during the polio epidemic of the early 1900s. [2] In modern surgical practice, Jackson's(More)
