Constructive, practical approach of spectral solutions to non-standard differential problems
Numerous and varied examples assist the reader in smoothly understanding and learning
Text shows what kind of spectral method works for a particular problem and how it can be efficiently implemented
Less academic examples but more real examples from elasticity and hydrodynamics
Complete solutions for classical Mathieu’s system as a multi parameter eigenvalue problem, i.e., in its natural setting
This book focuses on the constructive and practical aspects of spectral methods. It rigorously examines the most important qualities as well as drawbacks of spectral methods in the context of numerical methods devoted to solve non-standard eigenvalue problems. In addition, the book also considers some nonlinear singularly perturbed boundary value problems along with eigenproblems obtained by their linearization around constant solutions.
The book is mathematical, poising problems in their proper function spaces, but its emphasis is on algorithms and practical difficulties. The range of applications is quite large. High order eigenvalue problems are frequently beset with numerical ill conditioning problems. The book describes a wide variety of successful modifications to standard algorithms that greatly mitigate these problems.
In addition, the book makes heavy use of the concept of pseudospectrum, which is highly relevant to understanding when disaster is imminent in solving eigenvalue problems. It also envisions two classes of applications, the stability of some elastic structures and the hydrodynamic stability of some parallel shear flows.
This book is an ideal reference text for professionals (researchers) in applied mathematics, computational physics and engineering. It will be very useful to numerically sophisticated engineers, physicists and chemists. The book can also be used as a textbook in review courses such as numerical analysis, computational methods in various engineering branches or physics and computational methods in analysis.

IRC: 37-2012 Guidelines for The Design of Flexible Pavements (3rd Revision)
Size: 4.6 MB | Format:PDF | Quality:Original preprint | Publisher: Indian Roads Congress | Year: July, 2012 | pages: 94
SCOPE OF THE GUIDELINES
The Guidelines shall apply to the design of new flexible pavements for Expressways, National Highways, State Highways, Major District Roads and other categories of roads predominantly carrying motorized vehicles. These guidelines do not form a rigid standard and sound engineering judgment considering the local environment and past pavement performance in the respective regions should be given due consideration while selecting a pavement composition.
For the purpose of the guidelines, flexible pavements include pavements with Bituminous surfacing over:
(i) Granular base and sub-base
(ii) Cementitious bases and sub-bases with a crack relief layer of aggregate interlayer below the bituminous surfacing
(iii) Cementitious bases and sub-bases with SAMI in-between bituminous surfacing and the cementitious base layer for retarding the reflection cracks into the bituminous layer
(iv) Reclaimed Asphalt Pavement (RAP) with or without addition of fresh aggregates treated with foamed bitumen/bitumen emulsion
(v) Use of deep strength long life bituminous pavement
These guidelines shall not be straightway applied to overlay design for which IRC 81-997 or a more suitable procedure based on evaluation of in situ properties of pavement layers by Falling Weight Deflectometer (FWD) should be used (25,56).

Covers a wide range of topics, from composite structures, via fire engineering and masonry structures, to timber engineering. Valuable reference for academics, researchers and practising engineers working in structural engineering and structural mechanics.
Summary
Incorporating Sustainable Practice in Mechanics of Structures and Materials is a collection of peer-reviewed papers presented at the 21st Australasian Conference on the Mechanics of Structures and Materials (ACMSM21, Victoria, University, Melbourne, Australia, 7th – 10th of December 2010). The contributions from academics, researchers and practising engineers from 17 countries, mainly from Australasia and the Asia-pacific region, cover a wide range of topics, including:
• Composite structures
• Computational mechanics
• Concrete structures
• Dynamic analysis of structures
• Earthquake and wind engineering
• Fibre composites
• Fire engineering
• Geomechanics and foundation engineering
• Masonry structures
• Mechanics of materials
• Shock and impact loading
• Steel and aluminium structures
• Structural health monitoring

Comprehensively covers durability from a mechanistic perspective
Links each durability problem to the solutions provided in Standards, UK and European guidance documents and best practice.
Covers repair and rehabilitation techniques for restoring serviceability
Summary
Written specifically for the young professional and addressing a growing need for a long service life with minimal maintenance, Concrete Durability takes a whole new look at the whole-life performance of structures. This text examines physical and chemical issues that can threaten the durability of concrete.
It explores available options for achieving appropriate durability, examining how durable concrete can be specified and designed, with emphasis placed on the European standards. The author brings together methods and procedures needed for durability assessment and testing, as well as repair and rehabilitation. The book introduces an approach that identifies what causes deterioration, what factors influence deterioration, and what is required to minimize the rate of deterioration.
The author also:
Considers the aspects of the construction process, which can influence durability
Factors in technologies that can be employed at the start of a structure’s service life to enhance resistance to deterioration
Explores the issue of service life and serviceability
Observes how durability problems in a structure can be identified
Suggests how future deterioration might be predicted and how deteriorated concrete can be repaired
This text promotes an understanding of how concrete elements in structures deteriorate. It also determines what must be done to protect structures from rapid deterioration and how existing durability problems can be identified and resolved.
