  • This book reports the latest development and trends in the low Re number aerodynamics, transition from laminar to turbulence, unsteady low Reynolds number flows, experimental studies, numerical transition modelling, control of low Re number flows, and MAV wing aerodynamics. This book focuses particularly on: (1) a review and brief information study on low Reynolds number flows and transition as an introduction to low Re number aerodynamics (Chapter 1), (2) transition modelling (Chapters 2-4), flow control (Chapters 5-7).

  • The modelling of traffic flow using methods and models from physics has a long history. In recent years especially cellular automata models have allowed for large-scale simulations of large traffic networks faster than real time. On the other hand, these systems are interesting for physicists since they allow to observe genuine nonequilibrium effects. Here the current status of cellular automata models for traffic flow is reviewed with special emphasis on nonequilibrium effects (e.g. phase transitions) induced by on- and off-ramps.

  • Road traffic microsimulations based on the individual motion of all the involved vehicles are now recognized as an important tool to describe, understand, and manage road traffic. Cellular automata (CA) are very efficient way to implement vehicle motion. CA is a methodology that uses a discrete space to represent the state of each element of a domain, and this state can be changed according to a transition rule.

  • Rheology involves the study of the deformation and flow of matter. The goal is to establish relationships between stress and deformation for (non-Newtonian) materials where neither Newton's law nor Hooke's law suffice to explain their mechanical behaviour. Many materials exhibit a non-Newtonian behaviour and the area is relevant in many fields of study from industrial to technological applications such as concrete technology, geology, polymers and composites, plastics processing, paint flow, hemorheology, cosmetics, adhesives, etc ......

  • The term "transition" is introduced whenever a channel's cross-sectional configuration (shape and dimension) changes along its length. Beside it, in the water control design, engineers need to provide for the dissipation of excess kinetic energy possessed by the downstream flow. Formulas for design calculation of transition works and energy dissipators are presented in this chapter

  • Energy is defined as the capacity of a substance to do work. It is a property of the substance and it can be transferred by interaction of a system and its surroundings. The student would have encountered these interactions during the study of Thermodynamics. However, Thermodynamics deals with the end states of the processes and provides no information on the physical mechanisms that caused the process to take place. Heat Transfer is an example of such a process. A convenient definition of heat transfer is energy in transition due to temperature differences.

  • Inspired by Lorenz’ remarkable chaotic flow, we describe in this paper the structure of all C 1 robust transitive sets with singularities for flows on closed 3-manifolds: they are partially hyperbolic with volume-expanding central direction, and are either attractors or repellers. In particular, any C 1 robust attractor with singularities for flows on closed 3-manifolds always has an invariant foliation whose leaves are forward contracted by the flow, and has positive Lyapunov exponent at every orbit, showing that any C 1 robust attractor resembles a geometric Lorenz attractor. ...

  • The issue of sustainability has a number of dimensions, some of which were already mentioned. The one addressed here is the sustainability of subprojects. This issue comes up when the transition of social funds from the emer- gency or crisis mode to the longer term is examined. The transition is essentially the change from building a facility to delivering an ongoing service. By implication, how the services are being used needs to be monitored and evaluated, not just what was disbursed or built.

  • Greenplum’s SG Streaming™ technology ensures parallelism by “scattering” data from all source systems across hundreds or thousands of parallel streams that simultaneously flow to all Greenplum Database nodes (Figure 11). Performance scales with the number of Greenplum Database nodes, and the technology supports both large batch and continuous near-real-time loading patterns with negligible impact on concurrent database operations.

  • Along with providing more realistic views of ecosystem service provision and use, these flow maps can also enable improved value transfer. A better understanding of the relative strength of flow can identify regions more likely to provide higher or lower levels of value (Boyd and Wainger 2003). Indeed the flow of benefits is the only quantity that relates supply and demand and is a natural candidate for a quantitative statement of value. In order for a flow of benefit to exist, a potential for provision must coexist with a need for use; the marginal value is determined by the “difference...
