Timetabling hub-and-spoke parcel distribution inter-facility network
Published 2013“…This problem, which comes after generating the network design and before implementing it, is concerned with parcel timetabling. A non-linear model, composed of the shipping-time objective function and the time-precedence constraints, is developed in order to optimise the daily movements of parcels from their origins to their destinations. …”

Kappa-Distributed Electrons in Solar Outflows: Beam-Plasma Instabilities and Radio Emissions
Published 2023“…The frequency downshift, also revealed by the observations, clearly tends to increase in the presence of a Kappa-distributed beam. Particle-in-cell (PIC) simulations confirm the inhibiting effects of (initially) Kappa-distributed electrons, but these minor effects in the linear and quasi-linear phases unexpectedly lead to significant decreases in the wave energy levels of the (primary) ES fluctuations near the plasma frequency and higher harmonics. …”

Biocorrosion behavior of biodegradable nanocomposite fibers coated layer-by-layer on AM50 magnesium implant
Published 2016“…The corrosion performance of coated and uncoated coupon samples was investigated by means of electrochemical measurements. The results showed that the AJS 3D membrane fiber layers, particularly the hybrid membrane layers containing a small amount of nHA (3wt.%), induce a higher biocorrosion resistance and effectively decrease the initial degradation rate compared with the neat AM50 coupon samples. …”
