Beach profile model with size-selective sediment transport. I: laboratory experiment and sensitivity study
(Asce-Amer Soc Civil Engineers, 2015)The response of physical models of beach profiles to random breaking waves was studied to investigate size-selective sediment transport and cross-shore profile evolution. Three types of beach profiles with different sediment ... -
Analytical and finite element solution of a receding contact problem
(Techno-Press, 2015)In this paper, a receding contact problem for an elastic layer resting on two quarter planes is considered. the layer is pressed by a stamp and distributed loads. It is assumed that the contact surfaces are frictionless ... -
Structure and giant inverse magnetocaloric effect of epitaxial Ni-Co-Mn-Al films
(Institute of Electrical and Electronics Engineers Inc., 2015)In the ongoing search for magnetocaloric materials, Heusler compound based ferromagnetic shape memory alloys (FSMA) of the system Ni-Mn-Z (Z=Sb, Ga, In, Sn) turned out to be very promising due to low cost of the containing ... -
Graphene-metallic nanocomposites as modifiers in electrochemical glucose biosensor transducers
(Iop Publishing Ltd, 2016)Graphene sheets and three different graphene-metallic nanocomposites including graphene-copper (graphene-Cu), graphene-nickel (graphene-Ni) and graphene-platinum (graphene-Pt) were prepared and characterized in the first ... -
