opticalnetworkdesign and modelling is an essential issue for planning and operating networks for the next century. The main issues in opticalnetworking are being widely investigated, not only for WDM networks but also for optical TDM and optical packet switching. This book contributes to further progress in opticalnetwork architectures, design, operation and management and covers the following topics in detail: Routing strategies and algorithms for opticalnetworks; network planning and design; Wavelength conversion and wavelength assignment in opticalnetworks; Technologies for opticalnetworks (transport, access and local area networks); Transmission aspects in wide area opticalnetworks; New paradigms for traffic modelling. This book contains the selected proceedings of the Second international Working conference on opticalnetworkdesign and modelling, which was sponsored by the international Federation for Information Processing (IFIP), and held in February 1998, in Rome, Italy. This valuable new book will be essential reading for personnel in computer/communication industries, and for academic and research staff in computer science and electrical engineering.

Lattice structures are defined by the organised repetition of a unit cell. These complex designs are widely used in engineering due to their lightweight nature and tailored mechanical properties. This study presents a novel 1D numerical method for modelling the standard Body-Centered Cubic (BCC) unit cell, a commonly used lattice structure geometry due to its geometry simplicity. Mechanical analyses were carried out using Ansys 2023 R2. A customised ANSYS Parametric design Language (APDL) routine was developed to assign specific area and inertia properties to each beam element, independent from the nominal value of the strut diameter. The equivalent engineering constants were evaluated through uniaxial compression and in-plane shear tests. A neural network optimisation technique was then employed to optimise the 1D model's parameters and improve its accuracy. The neural network was trained using high-fidelity 3D FEM results as the reference data, enabling the identification of the most suitable parametric values for various strut diameters. The proposed 1D method aims to address the computational complexity associated with traditional 3D FEM analyses while maintaining accurate predictions of the mechanical response. By representing the lattice struts as beam elements in the 1D model, the computational cost can be significantly reduced, making it more feasible to analyse large-scale lattice structures or perform extensive parametric studies involving different design configurations and loading scenarios. This formulation has been tested by comparing numerical results coming from standard 3D and 1D elements on a variable span 3-point bending test. The accuracy of results and time-saving demonstrate the validity of the proposed procedure.
