In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal ...

In this work, single-stage and two-stage tubular solid oxide fuel cell (SOFC)/gas turbine hybrid cycles are comparatively examined from the energy and exergy viewpoints. For this purpose, mass, energy and exergy balances ...

In this work, Poly(ethyleneterephthalate) (PET) substrate was treated using KOH solution and was modified using hybrid O-I coating containing PCL )polycaprolactone( as organic phase and TEOS )tetraethoxysilane( as inorganic ...

The rheological and tape casting behavior of ethanol-based Bi0.5(Na0.80K0.20)0.5TiO3-7 mol% BiFeO3 (BNKT-BF) slurries was investigated. The effect of sintering temperature profile on texture development with a preferred ...

Slewing bearing, which is widely applied in tank, excavator and wind turbine, is a critical component of rotational machine. Standard procedure for bearing life calculation and condition assessment was established in general ...

The heat pipe applications have been coupled with the renewable energy such as solar energy, waste heat and geothermal energy. Thermosyphon Rankine Cycle (TRC) is a vertical wickless heat pipe engine. In this engine, the ...

The significant costs insert on mineral processes due to mill liner wear including the labor costs, price of material and shut down periods. Therefore, the study of this phenomenon is economically important to optimize the ...

This paper presents exergy and exergoeconomic analysis and parametric study of a Diesel engine based Combined Heat and Power (CHP) system that produces 277 kW of electricity and 282 kW of heat. For this purpose, the CHP ...

In this paper, the path following controller of an omnidirectional mobile robot (OMR) has been extended in such a way that the forward velocity has been optimized and the actuator velocity constraints have been taken into ...

The Performance of electric vehicle IGPT Pin fin heat sink can be measured by the temperature field and the fluid pressure and other parameters. In order to improve the cooling effect of Pin fin heat sink, diameter, length ...

The nonlinear solvers in numerical solution of water flow in variably saturated soils are prone to convergence difficulties. Many aspects can give rise to such difficulties, like very dry initial conditions, a steep pressure ...
