Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters. They present principal modelling approaches, synthesizing fundamental material related to mechanical, aerospace, civil, electrical and materials engineering disciplines for vibration-based energy harvesting using piezoelectric transduction. Piezoelectric Energy Harvesting provides the first comprehensive treatment of distributed-parameter electromechanical modelling for piezoelectric energy harvesting with extensive case studies including experimental validations, and is the first book to address modelling of various forms of excitation in piezoelectric energy harvesting, ranging from airflow excitation to moving loads, thus ensuring its relevance to engineers in fields as disparate as aerospace engineering and civil engineering. Coverage includes: Analytical and approximate analytical distributed-parameter electromechanical models with illustrative theoretical case studies as well as extensive experimental validations Several problems of piezoelectric energy harvesting ranging from simple harmonic excitation to random vibrations Details of introducing and modelling piezoelectric coupling for various problems Modelling and exploiting nonlinear dynamics for performance enhancement, supported with experimental verifications Applications ranging from moving load excitation of slender bridges to airflow excitation of aeroelastic sections A review of standard nonlinear energy harvesting circuits with modelling aspects.

Book Description
Collection, like transport and storage, is one of the basic technical and economic components of the processes of converting Biomass into energy. In recent years much progress has been made in R&D and industrial appli cations for the collection of all types of Biomass resources/feedstock, which ranges from orchard prunings to tree-felling waste, from straw to seaweed, from specific energy crops to arable-farming residues of any kind. Though interesting results have certainly been achieved, many problems still remain, and their solution will largely influence the final use of these Biomass sources and residues. There are the problems of bringing out timber waste from inaccessible oak forests, and making the collection of algae and aquatic plants financially worthwhile j should ma chines be specially designed for this work j and what about the economic and social costs for a proper forest management policy such as forest fires, soil degradation and so on. The need to assess what positives advances have already been made in the Community's member countries, so that Community action in this sector can be directed most efficiently, prompted the Directorate-General for Energy of the Commission of the European Communities to organize this workshop in collaboration with the other departments active in this field.
