Kinematics and critical swimming speed (Ucrit) of juvenile scalloped hammerhead sharks Sphyrna lewini were measured in a Brett-type flume (635 l). Kinematic parameters were also measured in sharks swimming in a large pond for comparison with those of sharks swimming in the flume. Sharks in the flume exhibited a mean Ucrit of 65±11 cm s-1 (± s.d.) or 1.17±0.21 body lengths p...

recognizing of river flow pattern, deposition and erosion areas in meanders is highly important. despite the limitations of the physical models in laboratory investigation of flow pattern in meanders, mathematical models can be helpful. in this research, rsm and les turbulence models have been compared on sharp river bend of a laboratory flume using fluent software. the laboratory flume is a sh...

Seagrass beds and the communities they form are well known for their ability to alter their local hydrodynamic environment, reducing current velocities and altering turbulent structure in and around the canopy. Much of the quantitative information that has been published on the interaction of seagrass canopies with flowing water has been derived from laboratory flume studies. The few studies th...

The WinWin framework provides a domain independent framework for the stakeholders to collaborate and negotiate in the requirements engineering phase of the software lifecycle. Requirements engineering in the framework leads to defining a win-win requirements model expressed using a set of conceptual elements that record stakeholder’s objectives, constraints, concerns and negotiated agreements. ...

This chapter describes a new sustainable business model, Innovation 2.0, led and deployed by the author, with the goal of increasing the innovation level at the telco service portfolio for the end-user, thank to the convergence of Internet and Telco worlds and the ‘fresh’ and ‘effervescent’ proposals created by start-ups. This model, created by Win Win Consultants, a Spanish company leader in m...

Alternate bars were formed by sediment transport in a flume with Froude-modelled flow and relative roughness characteristic of gravel-boulder channels with steep slopes. The flume (0.3 m wide x 7.5 m long) was filled with a sand-gravel mixture, which was also fed into the top of the flume at a constant rate under constant discharge. Channel slope was set at 0.03. Initially, coarse particles acc...
