The aim of the book is to present the emerging environmental issues in organization and management of transport logistics. The scope of the book includes set of solutions which show different stakeholders’ viewpoints on sustainability. It points out how the transport operations organized and conducted in companies and regions might be consistent with the concept of sustainable development. The scope of the book takes into consideration trade-off relations between actors directly and indirectly involved in transport networks. Therefore, the authors present, in individual chapters, innovative approach to eco-friendly organization and coordination of transport processes, as well as management of transport networks.

Smart Sensors for Real-Time Water Quality Monitoring (Smart Sensors, Measurement and Instrumentation)
Author: Subhas C Mukhopadhyay and Alex Mason | Size: 11 MB | Format:PDF | Quality:Unspecified | Publisher: Springer | Year: 2013 | pages: 300 | ISBN: 3642370055
Sensors are being utilized to increasing degrees in all forms of industry. Researchers and industrial practitioners in all fields seek to obtain a better understanding of appropriate processes so as to improve quality of service and efficiency. The quality of water is no exception, and the water industry is faced with a wide array of water quality issues being present world-wide.
Thus, the need for sensors to tackle this diverse subject is paramount. The aim of this book is to combine, for the first time, international expertise in the area of water quality monitoring using smart sensors and systems in order that a better understanding of the challenges faced and solutions posed may be available to all in a single text.

DYNAMIC RESPONSE OF CIRCULAR PLATES ON ELASTIC FOUNDATION SUBJECTED TO SONIC BOOMS
Author: ANESH SIRCAR, Department of Mathematics, Regional Engineering College, Durgapur 9 (Communicated by F. C. Auluck, (Received 2 November 1972; alter revision 2 April 1973) | Size: 0.55 MB | Format:PDF | Quality:Unspecified | Year: 1972 | pages: 9
The dynamic response of circular plates resting on elastic foundation subjected
to an N-shaped pressure pulse resulting from a sonic boom is presented here.
Case of a plate supported on Winkler type foundation is considered and solution
obtained. The solution is given for a plate restrained at the outer
boundary by means of supports which resist elastically both the transverse
displacements and rotations. The plate is analysed according to classical
plate theory, neglecting rotatory inertia and shear strains.

PURI Professor Emeritus Professor Civil, Architecture and Environmental Civil and Environmental Engineering Engineering Southern Illinois University University of Missouri Rolla Carbondale, IL, USA Rolla, MO, USA | Size: 0.86 MB | Format:PDF | Quality:Unspecified | Publisher: Journal of Structural Engineering, SERC, Madras.

The paper discusses the methods of analysis for determining the response of foundations subjected to vibratory loads. The design of a machine foundation is generally made by idealizing the foundation- soil system as spring-mass –dashpot model having one or two degrees of freedom. Most machine foundations are treated as surface footing and the soil spring and damping values are determined using the elastic-half space analog. The spring and damping values for response of embedded foundations can also be determined from the elastic half space concept as per Novak‟s work. The soil spring and damping values can also be obtained following the impedance –compliance function approach. The paper also presents a brief discussion of the predicted and observed response of machine foundations .

FOUNDATIONS FOR INDUSTRIAL MACHINES AND EARTHQUAKE EFFECTS
Author: K.G. Bhatia Center for Applied Dynamics D-CAD Technologies, New Delhi | Size: 0.36 MB | Format:PDF | Quality:Unspecified | Publisher: ISET Journal of Earthquake Technology, Paper No. 495, Vol. 45, No. 1-2, March-June 2008, pp. 13–29 | Year: june2008 | pages: 17
Improvement in manufacturing technology has provided machines of higher ratings with better tolerances and controlled behaviour. These machines give rise to considerably higher dynamic forces and thereby higher stresses and, in return, demand improved performance and safety leaving no room for failures. This paper highlights need for a better interaction between foundation designer and machine manufacturer to ensure improved machine performance. The paper also describes the design aids/methodologies for foundation design. Various issues related to mathematical modeling and interpretations of results are discussed at length. Intricacies of designing vibration isolation system for
heavy-duty machines are also discussed. Influences of dynamic characteristics of foundation elements, viz., beams, columns, and pedestals etc. on the response of machine, along with some case studies, are also presented. The paper also touches upon the effects of earthquakes on machines as well as on their foundations. Use of commercially available finite element packages, for analysis and design of the foundation, is strongly recommended, but with caution.
