A bidirectional axial flow pump can realize bidirectional pumping, which has a wide application prospect in coastal low-head pumping stations and water jet propulsion systems.In this paper, a typical bidirectional axial medline remedy phytoplex protectant z-guard paste flow pump is taken as the research object, and the hydraulic model of the bidire
In this article we assess the appropriateness of the constant volatility assumption required by the Black (1976) option pricing model for options on nova upright walker the All Share Index future.The assessment uses similar nonparametric tests as implemented in Rubinstein for data recorded over the 1992 to 1996 period.In the nonparametric tests we
This paper introduces a novel four-port antenna array designed for n260 band operation, specifically addressing challenges like path loss fading and multipath effects commonly encountered fluffy tangerine clouds in millimeter-wave frequencies in urban settings.The proposed $4 imes 4$ MIMO antenna array operates in the n260 band, offering high gain
