Power counting is a systematic strategy for organizing collider observables and their associated theoretical calculations. In this paper, we use power to characterize class of jet substructure called energy flow polynomials (EFPs). EFPs provide an overcomplete linear basis infrared-and-collinear safe observables, but it known that in practice, small subset often sufficient specific analysis tas...

abstract stepped spillways are of most important hydraulic constructions to dissipation energy of water flow. these constructions are used in opening channel to transfer water from upper level to lower level. because of considerable effect of steps on flow dissipation energy and also the resulted developments in construction of roller competed concrete rcc, the mentioned constructions have draw...

The rapid advances in processor, memory, and radio technology enable the development of small, inexpensive sensor nodes that are capable of sensing, computation, and communication. However, the severe energy constraints of the sensors present major challenges for long-term applications. In order to achieve sustainability, environmental energy harvesting has been demonstrated as a promising appr...

This paper studied the coupling model of material flow and energy flow in the production process of lead smelting enterprises, and established the mathematical model for material flow and energy flow to resolve optimization problems. From the point of energy flow, the paper analyzed three kinds of energy flow changes which have an effect on the enterprise products. Through calculation and analy...

In this paper we give an example of a real-analytic Hamiltonian system whose restrictions onto different energy levels are Anosov flows for E > Ecr, have only transitive trajectories for E = Ecr and are analytically integrable for E < Ecr where E|mathrmcr is some critical level of energy. This gives a simple example of a transition from chaos to integrability (on a fixed energy level) via a pas...

Characteristics of rotor blade tip clearance flow in axial compressors can significantly affect their performance and stable operation. It may also increase blade vibrations and cause detrimental noises. Therefore, this paper is contributed to investigate tip leakage flow in a low speed isolated axial compressor rotor blades row. Simulations are carried out on near-stall condition, which is val...
