Tradeoff analysis is a central aspect of any design process. Languages and tools to support performance modeling and tradeof analysis are necessary to facilitate rapid prototyping of designs. An effective modeling and evaluation environment reduces the overall design time of both the prototype and the final product by helping designers in determining which parameters of a design are critical fo...

BACKGROUND The rapid adoption of point-of-care ultrasound (POCUS) has created a need to develop assessment tools to ensure that learners can competently use these technologies. In this study, the authors developed and tested a rating scale to assess the quality of point-of-care thoracic ultrasound studies performed by novices. In Phase 1, the Assessment of Competency in Thoracic Sonography (ACT...

Over the years, the focus has been on protecting network, host, database and standard applications from internal and external threats. The Rapid Application Development (RAD) process makes the web application extremely short and makes it difficult to eliminate the vulnerabilities. Here we study web application risk assessment technique called threat risk modeling to improve the security of the ...
