This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...

Investments in the capital market have a high level of risk but also provide profits, so it is very important to know changes macroeconomic variables and investor behavior. In this study will examine effect money supply, inflation volume, transactions on Consumer Goods Index.The partial test results show that supply transaction volume significant positive consumer goods index, has no index.Simu...

USDA Forest Service Res. Note PSW-RN-414-WEB. 1993. E xperienced hydrologists and geomorphologists can estimate the relative mobility of a streambed by looking at indicators of bedload transport, such as the freshness of bed-surface material. Another such indicator is the amount of fine sediment in pools. Pools in gravelbed streams commonly contain deposits of fine sediment (mostly sand and gra...

one effective method for improving the performance of supply chain is making coordination among members of supply chain. this paper studies the subject of coordination of supply chain by using an insurance contract. the supply chain consists of one-manufacturer and one-retailer that the retailer is faced with potential demand and returning of goods from customer. acceptance of goods returned is...

This research provides an investigation about the world’s economic situation and the environ...

Measurement of blood flow through the portal vein of the dog revealed a reduction of flow and an increase in vascular resistance of the mesenteric bed in proportion to the elevation of portal venous pressure. To obtain further information on this mechanism, studies were performed on segments of terminal ileuni with continuous measurement of both weight and flow. These studies demonstrated that ...
