H-bridge inverter is a common topology used for single-phase applications. Due to its limited voltage gain, two-stage power conversion with front-end dc-dc converter usually adopted accommodate the low dc source voltage. Recently, single-stage boost inverters are gaining significant interest due their higher efficiency and compactness. This paper presents family of continuous current. By incorp...

Initially recognized as an occupational cancer in male workers, MM was later found to occur in their family members as well. We report the case of an 89-year-old female who presented with abdominal distention, pain, and findings consistent with malignant ascites. Family history was significant...

This paper presents a theoretical model that combines employers learning about worker productivity, human capital acquisition, job-assignment and resolution of worker uncertainty regarding disutility of work from a job, to show how widely documented findings on both wage and promotion dynamics and turnover can be captured in a single set-up. Specifically we show how our model can capture result...
