This article investigates the performance of reconfigurable intelligent surface assisted two-way non-orthogonal multiple access (RIS-TW-NOMA) networks, where a pair users exchange their information through RIS. The influence imperfect successive interference cancellation on RIS-TW-NOMA is taken into account. To evaluate potential RIS-TW-NOMA, we derive exact and asymptotic expressions outage pr...

OBJECTIVE To evaluate the ability of a tissue-engineered nerve construct composed of a nerve guidance channel and neurally differentiated human adipose tissue-derived stem cells (hASCs) to enhance peripheral nerve regeneration in a rat sciatic nerve model. DESIGN A 13-mm sciatic nerve gap was bridged with silastic conduits in 64 athymic nude rats, and differentiated hASCs were implanted into ...

This experiment was conducted in attempt of improving hydrodynamic efficiency of the propulsion mechanism by installing a spring to the wing so that the opening angle of the wing in one stroke can be changed automatically, compared to the existing method of fixed maximum opening angle in Weis-Fogh type ship propulsion mechanism. Average thrust coefficient was almost fixed with all velocity rati...

Oxynotus centrina is considered a rare or uncommon shark species throughout its distribution range. Because of this reason, it one the 46 elasmobranchs in Mediterranean Sea, which requires filling knowledge gaps, such as length-weight relations. Based on analysis 34 angular rough sharks, relations (LWR) males, females and combined sexes O. were described W = 0.216L2.686, 0.134L3.041 W=0.102L3.1...

Anumerical study was conducted to investigate the effects of airfoil thickness on the thrust generation of plunging airfoils and to assess the contributions of pressure and viscous forces in flapping propulsion. A series of NACA symmetric airfoils with thickness ratio ranging from 4.0% to 20.0% of the airfoil chord length were used in the present study to undertake a same sinusoid plunging moti...

A procedure for estimating fuel burned based on actual flight track data, and drag and fuel-flow models is described. The procedure consists of estimating aircraft and wind states, lift, drag and thrust. Fuel-flow for jet aircraft is determined in terms of thrust, true airspeed and altitude as prescribed by the Base of Aircraft Data fuel-flow model. This paper provides a theoretical foundation ...

This study aimed to investigate some morphological features and heavy metal accumulation in muscle tissue of Ruditapes decussatus (Linnaeus, 1758) the spring autumn seasons 2018 Yumurtalık Coastline İskenderun Bay located northeastern Mediterranean Sea. To this end, shell length (SL), total weight (TW), height (SH), inflation (SI), (SW), roundness index (RI), cup (CI) length-weight relationship...

Introduction T HE propulsion system of a short takeoff and vertical landing aircraft, such as the F-35 Joint Strike Fighter, must operate over a wide range of conditions, provide good fuel efficiency at cruise, and deliver high thrust in augmented mode for transonic acceleration and supersonic operation. The propulsion system must be efficient for both high-speed flight and during hover, while ...
