SIMPLE APPROXIMATIONS FOR THE RUIN PROBABILITY IN THE RISK MODEL WITH STOCHASTIC PREMIUMS AND A CONSTANT DIVIDEND STRATEGY

Simple approximations for the ruin probability in the risk model with stochastic premiums and a constant dividend strategy

We deal with a generalization of the risk model with stochastic premiums where dividends are paid according to a constant dividend strategy and consider heuristic approximations for the ruin probability.To be more precise, we construct five- and three-moment analogues to Books the De Vylder approximation.To this end, we obtain an explicit formula f

Closed-form critical response of elastic-plastic shear building with viscous damper under pseudo-double impulse for simulating resonant response under near-fault fling-step motion

A set of approximate closed-form solutions of the maximum interstory drifts under the critical pseudo-double impulse (PDI) is derived for non-proportionally damped multi-story shear building models with bilinear hysteresis.The use of PDI and the closed-form solutions efficiently and accurately enable the capture of the critical responses of elastic

Computer ontology as an instumental platform to ensure transparency of the European and national qualifications frameworks

The article analyzed the instrumental platforms of European and national qualifications frameworks.It was found that the European Qualifications Framework contains eight interrelated levels where qualifications determined by training results - triad professional qualities: knowledge, skills and competencies.This approach helps to compare qualificat

Retroperitoneal abscess with subcutaneous extension: case report of a rare complication of percutaneous renal biopsy

Abstract Background Infective complications following percutaneous renal biopsy are rare, even among immunocompromised.However it is important to be vigilant about such complications, to detect Collections them early and prevent morbidity and mortality.We report a case of retroperitoneal abscess with extension to subcutaneous plane after a renal bi
