Model-Centric Fulfillment Operations and Maintenance Automation

As networks have evolved, there has been an evolution in how they are managed as well. This evolution has seen a move from manual configuration via command line interface (CLI) to script-based automation and eventually to a template-based approach with workflow to coordinate multiple templates and scripts. The next step in this evolution is the introduction of models to provide a more dynamic capability than is in place today. This chapter will discuss three major layers of modelling that should be considered during implementation of this approach: device models focused on the configuration of the hardware itself; service models focused on the customer or network facing services that leverage the hardware level configuration; and operational models focused on people, processes, and tools involved in application of device and service models. This includes the orchestration of activities with other tools, such as operational support systems (OSS) and business support systems (BSS).

EEG Cross-Frequency Phase Synchronization as an Index of Memory Matching in Visual Search

Visual perception is influenced by our expectancies about incoming sensory information. It is assumed that mental templates of expected sensory input are created and compared to actual input, which can be matching or not. When such mental templates are held in working memory, cross-frequency phase synchronization (CFS) between theta and gamma band activity has been proposed to serve matching processes between prediction and sensation. We investigated how this is affected by the number of activated templates that could be matched by comparing conditions where participants had to keep either one or multiple templates in mind for successful visual search. We found that memory matching appeared as transient CFS between EEG theta and gamma activity in an early time window around 150ms after search display presentation, in right hemispheric parietal cortex. Our results suggest that for single template conditions, stronger transient theta-gamma CFS at posterior sites contralateral to target presentation can be observed than for multiple templates. This lends evidence to the idea of sequential attentional templates and is understood in line with previous theoretical accounts strongly arguing for transient synchronization between posterior theta and gamma phase as a neuronal correlate of matching incoming sensory information with contents from working memory.

Template-based Analyses and Min-policy Iteration

This chapter considers other configurations aside from the direct synthesis of invariants as bound templates. A first case arises when the methods shown in the previous chapter only synthesizes the template but not the bound. A second appears when one wants to analyze a system with multiple templates. This chapter looks at bounds on each variable and considers the templates 𝑝‎(𝑥‎) = 𝑥²‎𝑖‎ for each variable 𝑥‎𝑖‎ in state characterization 𝑥‎ ∈‎ Σ‎. The chapter thus proposes a policy iteration algorithm, based on sum-of-squares (SOS) optimization, to refine such template bounds. In practice, the chapter uses it by combining a Lyapunov-based template obtained using one of the previous methods with additional templates encoding bounds on some variables or property specific templates.

A block-queue based optimization method for composite structures blended with multiple templates

Maintaining the continuity (blending) of stacking sequences is very vital when the stacking sequences of a multi-region panel is being optimized. The traditional attempt simplifies the difficulty of the blending problem by designing the whole panel based on one stacking template. However, this simplification adds an unnecessary constraint that regions with the same thickness should have the same stacking sequence. In order to overcome the drawback, this paper introduces a region block queue based method to obtain the optimal manufacturable stacking sequences of composite laminates blended from multiple stacking templates. The method discussed here groups regions into blocks, forming a block queue, and designs the entire laminate panel with multiple stacking templates, which are respectively applied to different blocks. The continuity between two adjacent blocks is guaranteed by sequentially rebuilding the template of a block from the sequences of adjacent regions within its previous block in the queue. An 18-region benchmark problem is chosen to prove the effectiveness of the proposed method, and the solution obtained is 0.27kg lighter than the traditional template-based method. The reduction of mass reveals that the use of multiple templates does contribute to searching for lighter solution.
