INTRODUCTION Simulation is becoming an increasingly popular educational tool in numerous surgical specialities, including urology. This article reviews the current role of urological simulators; discussing their need, availability, incorporation and current limitations. MATERIAL AND METHODS A literature review of the electronic databases Medline, Embase(More)
BACKGROUND Basic surgical skills training is rarely emphasised in undergraduate medical curricula. However, the provision of skills tutorials requires significant commitment from time-constrained surgical faculty. PURPOSE We aimed to determine how a peer-assisted suturing workshop could enhance surgical skills competency among medical students and enthuse(More)
—This paper demonstrates a risk-based framework that can be used to establish operational constraints of power systems. The application of this methodology is illustrated on the areas of small disturbance stability and sub-synchronous resonance (SSR) in order to determine risk levels associated with various operating regions (conditions). By visualizing(More)
This paper presents a risk-based Probabilistic Small-disturbance Security Analysis (PSSA) of a mixed AC/DC power system. The proposed approach establishes the probability density functions (pdfs) for the critical system modes based on the stochastic variation of operational system uncertainties (such as generation, loading, and HVDC line power flows).
