We introduce a new class of edge labelings for locally finite lattices which we call SB-labelings. We prove for finite lattices which admit an SB-labeling that each open interval has the homotopy type of a ball or of a sphere of some dimension. Natural examples include the weak order, the Tamari lattice, and the finite distributive lattices.

The tidal flow between bridge pillars and through open barriers is a promising source of ocean energy which can be exploited using stream turbines, as proven recently by operational demonstration plants. aim this study to clarify the consequences for power output turbines when placing them in hydraulic structure. To end, experimental measurements turbine wakes are performed, down-scaled mounted...

River slopes can be changed due to an extreme event, e.g., a large-scale earthquake. This uplift riverbed greatly and thereby change the behavior of river flow into free or submerged overfall. Corresponding damage, including erosion, on bridge piers located in take place aforementioned conditions. A reconstructed pier same location would also experience similar impact if condition is not change...

Performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (VCE) could be considered as one of the main causes of bridges collapse. In most of bridge design codes, for seismic analysis of bridges, VCE is not taken into account or a distinguished method isn’t presented for assessment of VCE. In the present work, the effect of VCE on two existing...

Abstract. This work presents a hyperspectral reflectance dataset of macroplastic samples acquired using Analytical Spectral Devices (ASD) FieldSpec 4. Samples analyzed consisted pristine, artificially weathered, and biofouled plastic items debris collected in the docks Port Antwerp river Scheldt near Temse Bridge (Belgium). The signal each sample was measured controlled dry conditions an optica...

submerged breakwaters are one of the shore protective structures. any discontinuity in these breakwaters causes changes on current parameters including speed and water surface profile. in this paper, discontinuous submerged breakwaters were modelled to investigate the changes in the wave and flow pattern.to investigate the phenomenon, three models including a shore with constant slope, a shore ...

the shape of a submerged vane is a major factor in the design of a vane system and affects the performance and secondary currents generated by the vanes. this study investigated the effect of five vane shapes on bed sediment processes (local scour at the leading edge and transverse distribution of sediment downstream of the vanes) at four flow intensities for a total of 20 experiments. the resu...

in river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend. a helical motion results, causing erosion of the outer side of the bend. installation of submerged vanes on the stream bed can reduce erosion of the outer bank significantly. in th...
