This paper explores two boosting techniques for cost-sensitive tree classiications in the situation where misclassiication costs change very often. Ideally, one would like to have only one induction, and use the induced model for diierent misclassiication costs. Thus, it demands robustness of the induced model against cost changes. Combining multiple trees gives robust predictions against this ...

In this paper, a model for hybrid transmission expansion planning (TEP) and reactive power planning (RPP) considering demand response (DR) model has been presented. In this study RPP considered by TEP for its effects on lines capacity and reduction of system expansion costs. On the other hand the expansion of the transmission system is an important subject, especially dealing with the new i...

We investigate the importance of “what”-flexibility on top of “where”and “when”-flexibility for alternative emission control schemes that prescribe long-term temperature targets and eventually impose additional constraints on the rate of temperature change. We find that “what”-flexibility substantially reduces the compliance costs under alternative emission control schemes. When comparing polic...

Background: Space-Time Discounting Discounting is typically defined as the process of comparing the values of costs and benefits that occur at different times. This definition neglects where costs and benefits occur. For example, we might discount future costs and benefits because we care less about the welfare of people in the future, but we might also discount the welfare of people in differe...

In order to estimate economic values of productive traits (meat, milk and wool) in Taleshi native sheep breed of Iran, records from economic parameters and performance of local Taleshi flocks were used. The economic values of traits were used to select the maximum profit estimation also to study the sensitivity rate of the model the effects of 20 percent increase / decrease in the price of milk...
