Differential Transformation Method for Mechanical Engineering
Problems focuses on applying DTM to a range of mechanical
engineering applications. The authors modify traditional DTM to
produce two additional methods, multi-step differential
transformation method (Ms-DTM) and the hybrid differential
transformation method and finite difference method (Hybrid
DTM-FDM). It is then demonstrated how these can be a suitable
series solution for engineering and physical problems, such as the
motion of a spherical particle, nanofluid flow and heat transfer,
and micropolar fluid flow and heat transfer.
This book is based on the lectures and contributions of the NATO
Advanced Study Institute on "Nanoscience and Nanotechnology in
Security and Protection Against CBRN Threats" held in Sozopol,
Bulgaria, September 2019. It gives a broad overview on this topic
as it combines articles addressing the preparation and
characterization of different nanoscaled materials (metals, oxides,
glasses, polymers, carbon-based, etc.) in the form of nanowires,
nanoparticles, nanocomposites, nanodots, thin films, etc. and
contributions on their applications in diverse security and safety
related fields. In addition, it presents an interdisciplinary
approach drawing on the Nanoscience and Nanotechnology know-how of
authors from Physics, Chemistry, Engineering, Materials Science and
Biology. A further plus-point of the book, which represents the
knowledge of experts from over 20 countries, is the combination of
longer papers introducing the background on a certain topic, and
brief contributions highlighting specific applications in different
security areas.

Engineering where the large deviation principle of probability
finds application. Large deviations is a branch of probability
theory dealing with approximate computation of the probabilities of
rare events. It contains applications of the LDP to pattern
recognition problems like analysis of the performance of the EM
algorithm for optimal parameter estimation in the presence of weak
noise, analysis and control of non-Abelian gauge fields in the
presence of noise, and quantum gravity wherein we are concerned
with perturbation to the quadratic component of the
Einstein-Hilbert Hamiltonian caused by higher order nonlinear terms
in the position fields and their effect on the Gibbs statistics and
consequently quantum probabilities of events computed using the
quantum Gibbs state. The reader will also find in this book
applications of LDP to quantum filtering theory as developed by
Belavkin based on the celebrated Hudson-Parthasarathy quantum
stochastic calculus. Print edition not for sale in South Asia

development, decoupling, and applications of multi-component force
sensing systems. Force and moment information can be used as

data acquisition systems, etc.) as well as sophisticated
measurement methods such as mechano-magnetic, mechano-optical, etc.

This book deals with the theory of Poincaré--Birkhoff normal forms, studying symmetric systems in particular. Attention is focused on general Lie point symmetries, and not just on symmetries acting linearly. Some results on the simultaneous normalization of a vector field describing a dynamical system and vector fields describing its symmetry are presented and a perturbative approach is also used. Attention is given to the problem of convergence of the normalizing transformation in the presence of symmetry, with some other extensions of the theory. The results are discussed for the general case of dynamical systems and also for the specific Hamiltonian setting.

Chapters 2 to 4 focus on the spacecraft power system design
experience and review the latest typical design cases concerning
spacecraft power systems in China. More specifically, these
chapters also introduce readers to the topological structure and
key technologies used in spacecraft power systems. Chapters 5 to 7
address power system reliability and safety design, risk analysis
and control, and in-orbit management in China's spacecraft
engineering projects. The book's closing chapters provide essential
information on new power systems and technologies, such as space
nuclear power, micro- and nano-satellite power systems, and space
energy interconnection systems. An outlook on future development
trends rounds out the coverage.
A highly coveted objective of modern materials science is to
optimize multiple coupled functionalities in the same single phase
material and control the cross-response via multiple external
fields. One important example of such multi-functionality are
multiferroic materials where two or more ferroic properties are
intrinsically coupled. They include, among others, the
magneto-electric and magneto-structural materials, which are well
understood at the nano- and continuum length (and time) scales. The
next emerging frontier is to connect these two limiting scales by
probing the mesoscale physics of these materials. This book not
only attempts to provide this connection but also presents the
state-of-the art of the present understanding and potential
applications of many related complex multifunctional materials. The
main emphasis is on the multiscale bridging of their properties
with the aim to discover novel properties and applications in the
context of materials by design. This interdisciplinary book serves
both graduate students and expert researchers alike.
The book introduces 'the state of the art' of pulsed laser ablation
and its applications. It is based on recent theoretical and
experimental studies. The book reaches from the basics to advanced
topics of pulsed laser ablation. Theoretical and experimental
fundamental phenomena involved in pulsed laser ablation are
discussed with respect to material properties, laser wavelength,
fluence and intensity regime of the light absorbed linearly or
non-linearly in the target material. The energy absorbed by the
electrons leads to atom/molecule excitation, ionization and/or
direct chemical bond breaking and is also transferred to the
lattice leading to material heating and phase transitions.
Experimental non-invasive optical methods for analyzing these
phenomena in real time are described. Theoretical models for pulsed
laser ablation and phase transitions induced by laser beams and
laser-vapour/plasma interaction during the plume expansion above
the target are also presented. Calculations of the ablation speed
and dimensions of the ablated micro- and nano-structures are
performed. The validity and required refinement of different models
in different experimental conditions is provided. The pulsed laser
deposition process which bases on collecting the ablated particles
on a surface is analyzed in terms of efficiency and quality of the
deposited films as a function of ambient conditions, target
material, laser parameters and substrate characteristics. The
interaction between the incident laser and the ablation plasma is
analyzed with respect to its influence on the structures of the
deposited films and its capacity to generate high harmonics and
single attosecond pulses which are highly desirable in pump-probe
experiments.
