An organic Rankine cycle (ORC) is a power cycle employing an organic working fluid. The term ORC is also applied generally to any Rankine cycle with a low-grade heat source (80° – 300 o C). Because ORC are often employed in small-scale applications, use of positive displacement equipment is favored over the centrifugal units used in large-scale power plants. A key feature of a positive displace...

The problem of modifying a given graph to satisfy certain properties has been one of the central topics in parameterized tractability study. In this paper, we study the cycle contraction problem, which makes a graph into a cycle by edge contractions. The problem has been studied by Belmonte et al. [IPEC 2013] who obtained a linear kernel with at most 6k+6 vertices. We provide an improved kernel...

The Quantity Theory of Money and the Credit Creation have been major streams in study quantity money. Nowadays, monetary theory is dominated by because Monetarist School Rational Expectation are both advocates Money, which has resulted a sharp decrease scholars studying Creation. Nevertheless, two theories will ultimately converge. Given that reason, we propose new theory—Dynamic this paper, un...
