Thiadiazoloquinoxaline and benzodithiophene bearing polymers for electrochromic and organic photovoltaic applications
(Taylor & Francis Ltd, 2019)
Two novel thiadiazoloquinoxaline and benzodithiophene (BDT) bearing copolymers were designed and synthesized. Different BDT units (alkoxy and thiophene substituted) were used as donor materials and the effect of alkoxy and ...
Improved instantaneous power theory based current harmonic extraction for unbalanced electrical grid conditions
(Elsevier Science Sa, 2019)
This paper presents a novel harmonic extraction method named as "virtual input signal based instantaneous power theory (VIS-IPT)". In this study, VIS-IPT is tested in a shunt active power filter (SAPF) for improving the ...
Exergy analysis of a natural gas fuelled gas turbine based cogeneration cycle
(Inderscience Enterprises Ltd, 2019)
In this paper, the monthly-based annual performance of a natural gas fuelled gas turbine-based cogeneration cycle was analysed. The performance analysis of the system was investigated in three steps. First, the real system ...
Wide band fractal-based perfect energy absorber and power harvester
(Wiley, 2019)
In this article, a novel wide band polarization and incident angle independent metamaterial absorber (MA) and energy harvesting applications which operates at C (4GHz-8 GHz) and X (8GHz-12 GHz) is proposed. The unit-cell ...
Performance assessment of a marine freshwater generator through exergetic optimization
(Elsevier, 2019)
The objective of this study is to examine the effect of operating parameters on the freshwater generation capacity of a vacuum type and low-temperature single-stage freshwater generator and the exergy destruction of the ...
Off-the-Shelf Connectors for Interdisciplinary Components
(IOS Press, 2019)
Introduction: Solutions based on software components, especially for heterogeneous constituents such as those pertaining to different disciplines suffer the interoperability burden. Adaptor technologies have been introduced ...
Virtual Park-based control strategy for grid-connected inverter interfaced renewable energy sources
(Inst Engineering Technology-Iet, 2019)
Unbalanced grid faults are the most severe perturbations which degrade the performance of grid-connected inverter interfaced renewable energy sources (IIRESs). In this regard, this study proposes a novel control strategy ...
Gain-phase margins-based delay-dependent stability analysis of pitch control system of large wind turbines
(Sage Publications Ltd, 2019)
This paper investigates the effect of gain and phase margins (GPMs) on the delay-dependent stability analysis of the pitch control system (PCS) of large wind turbines (LWTs) with time delays. A frequency-domain based exact ...
Analysis of combined passively and actively morphing blade root chord length and blade taper for helicopter control
(Emerald Group Publishing Ltd, 2019)
Purpose The purpose of this study is to examine the effect of passive and active morphing of blade root chord length and blade taper on the control effort of the flight control system (FCS) of a helicopter. Design/method ...
