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.
Environmental challenges act as a spur to invention and innovation. R&D will continue to be important
as companies and investors seek disruptive technology solutions that can change the economics of,
and rewards from, new environmental products or processes. Significant private and public funds have
already been established, many of which are still investing despite the current economic slowdown.
The short‐term challenge is to ensure that these funds continue to flow and to sustain future growth.
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
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.
This book contains twelve chapters detailing significant advances and applications in fluid dynamics modeling with focus on biomedical, bioengineering, chemical, civil and environmental engineering, aeronautics, astronautics, and automotive. We hope this book can be a useful resource to scientists and engineers who are interested in fundamentals and applications of fluid dynamics.
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...
Chapter 2 - The market system and the circular flow. This chapter begins with a brief comparison of the command and market systems, transitioning quickly to a discussion of the institutional framework of the American market system.
Chapter 2 - The market system and the circular flow. This chapter begins with a brief comparison of command and laissez-faire systems, then transitions to a discussion of the characteristics of a market system. The five fundamental questions faced by every economy are presented along with how a market economy answers each one.
