This book presents the separation-of-variables and T-matrix methods of calculating the scattering of electromagnetic waves by particles. Analytical details and computer programs are provided for determining the scattering and absorption characteristics of the finite-thickness slab, infinite circular cylinder (normal incidence), general axisymmetric particle, and sphere.The computer programs are designed to generate data that is easy to graph and visualize, and test cases in the book illustrate the capabilities of the programs. The connection between the theory and the computer programs is reinforced by references in the computer programs to equations in the text. This cross-referencing will help the reader understand the computer programs, and, if necessary, modify them for other purposes.

Although the primary cause of autism has not yet been unravelled, a number of genetic conditions have been strongly associated with the behavioural triad of autism. We briefly review the underlying neuropathological, biological and genetic evidence of the possible mechanisms involved in autism. This knowledge should guide accurate investigation of the autistic individual and genetic counselling of parents and family members.

The neurobiology of autism.

Supply chain SC activities transform natural resources, raw materials, and components
into various finished products that are delivered to end customers. A high efficient
SC would bring great benefits to an enterprise such as integrated resources, reduced
logistics costs, improved logistics efficiency, and high quality of overall level of services.
In contrast, an inefficient SC will bring additional transaction costs, information
management costs, and resource waste, reduce the production capacity of all enterprises
on the chain, and unsatisfactory customer relationships. So the evaluation of a SC is
important for an enterprise to survive in a competitive market in a globalized business
environment. Therefore, it is important to research the various methods, performance
indicator systems, and technology for evaluating, monitoring, predicting, and
optimizing the performance of a SC. A typical procedure of the performance evaluation
(PE) of a SC is to use the established evaluation performance indicators, employ an
analytical method, follow a given procedure, to carry out quantitatively or qualitatively
comparative analysis to provide the objective and accurate evaluation of a SC
performance in a selected operation period. Various research works have been carried
out in proposing the performance indicator systems and methods for SC performance
evaluations. But there are no widely accepted indicator systems that can be applied in
practical SC performance evaluations due to the fact that the indicators in different
systems have been defined without a common understanding of the meanings and the
relationships between them, and they are nonlinear and very complicated.
In this chapter, the conception of SC performance is first presented, then relevant
theories about supply chain performance evaluation are discussed and several common
methods of supply chain performance evaluation are discussed. Finally, an evaluation
model is presented for SC performance evaluation using 5 dimensional balanced
scorecard (5DBSC) and Levenberg–Marquardt Back‐propagation (LM‐BP) neural
network algorithm.
