In this article, an estimation methodology based on the sequential Monte Carlo algorithm is proposed, thatjointly estimate states and parameters, relationship between prices of futures contracts spot primary products determined, evolution volatility historical data market (Gold Soybean) are analyzed. Two stochastic models for parameters considered, describe physical measure (associated with pri...

Most developed countries hold significant quantities of medical supplies in reserve for emergency response. Due to high handling costs and remote storage locations, such stocks are typically not used day-to-day operations. In consequence, the expiry (without use) is a problem. One possible remedy wastage donate large batches dated developing nations, which often do without adequate their health...
