In this paper particle swarm optimization with smart inertia factor (PSO-SIF) algorithm is proposed to solve combined heat and power economic dispatch (CHPED) problem. The CHPED problem is one of the most important problems in power systems and is a challenging non-convex and non-linear optimization problem. The aim of solving CHPED problem is to determine optimal heat and power of generating u...

This paper provides clear cut evidence that the slope and curvature factors of the yield curve contain more information about future changes in economic activity than the term spread alone, often used in practice as an indicator of future economic conditions. These two factors constitute independent sources of information about future economic activity, which are o¤set to each other in term spr...

Rural areas have always played a significant role in the global economy by providing a variety of foods and raw materials. This role is much more prominent in developing countries. Rural development is also an important part of regional policies, covering agriculture, forestry, natural resource management, land use, and economic diversity in these areas. The present study focused on investigati...
