Why Kalina (Ammonia-Water) cycle rather than steam Rankine cycle and pure ammonia cycle: A comparative and comprehensive case study for a cogeneration system
(Elsevier, 2022)
There are many studies on the Kalina cycle and steam Rankine cycles. However, there are not enough comparative and descriptive studies on why the Kalina cycle or steam Rankine cycle should be selected. In addition to that, ...
WEDM machining of MoNbTaTiZr refractory high entropy alloy
(Elsevier, 2022)
Refractory high entropy alloys (RHEAs) have shown great promise for a multitude of advanced engineering applications due to their high mechanical stability from cryogenic temperatures to 1600 °C. However, the low ductility ...
Dynamic models for air-breathing and conventional polymer electrolyte fuel cells: A comparative study
(Elsevier, 2022)
Two dynamic models have been built for air-breathing and conventional polymer electrolyte fuel cells (PEFCs) in order to comparatively investigate the impacts of some key parameters on the transient response to load ...
Diverse Properties and Approximate Roots for a Novel Kinds of the (p, q)-Cosine and (p, q)-Sine Geometric Polynomials
(MDPI, 2022)
Utilizing (p, q)-numbers and (p, q)-concepts, in 2016, Duran et al. considered (p, q)-Genocchi numbers and polynomials, (p, q)-Bernoulli numbers and polynomials and (p, q)-Euler polynomials and numbers and provided ...
The Theoretical Value for the Tip Radius of Cracks and Notches
(Kauno Technologijos Universitetas, 2022)
In this paper, an additional equation that can be used in conjunction with the Stress Intensity Factor is produced, enabling the determination of all critical fracture stresses, including tensile strength, from only one ...
Statistical analysis of maritime piracy cases in world territorial waters
(Springer, 2022)
In today’s international trading system, most cargoes are transported by sea. In parallel with increasing trade volume, shipping trade and thus maritime traffic are also increasing. The smooth functioning of global trade ...
Capacitance-based stress self-sensing in asphalt without electrically conductive constituents, with relevance to smart pavements
(Elsevier, 2022)
The capacitance-based stress self-sensing in asphalt without device or functional constituent incorporation is reported for the first time, with relevance to smart pavements. Stress sensing enables weighing. Without the ...
A vanadium dioxide-based metamaterial with quatrefoil and circle loaded structure on flexible polyamide substrate for terahertz applications
(Frontiers Media S.A., 2022)
In this study, a novel broadband metamaterial (MTM) absorber is proposed, which is based on vanadium dioxide (VO2) resonators coated onto a flexible polyamide substrate. The VO2 resonator is in the form of a quatrefoil and ...
Nonlinear optical performance and optical limiting of germanate glasses modified with PbF2 and B2O3 induced by nanosecond pulsed laser
(Elsevier, 2022)
In this work, GeO2 modified with PbF2 and B2O3 glasses were synthesized by conventional melting and quenching technique to investigate the effect of modifier network on its linear and nonlinear optical properties. Linear ...
Improving Asphalt Binder and Hot Mix Asphalt Aging Properties by Adding Synthetic Polyboron and Organic Magnesium Oxide
(Springer, 2022)
In this study, asphalt binders were modified with polymeric triethylene glycol-based polyboron (PTEGB) and organic-based magnesium oxide (OBMO) at different concentrations. The materials used as additives were synthesized ...
