Remote Management of Autonomous Factory

In today’s mass production era, the world is making things (products and systems) so quickly and systematically in huge volume. The demand for these products is very high and, at the same time, consumers are still in search for a need for making the production very personalized. Hence, the “one mold fits all” approach may not seem to be enough. The present approach is facing the lack of networking between the automation pyramid levels, that is, especially between enterprise resource planning (ERP) and manufacturing execution system (MES) layers and, in turn, communicating directly with the lower layers is not possible. This missing communication among the process equipment like machineries and field control systems like PLCs at the production shop floors implies that customization at the product layer for the consumer is still in progress in classical manufacturing. Mini-MES is a new concept being introduced here to solve the existing techniques reported in the literature and is followed by industry best practices. The novel mini-MES platform provides an avenue for the technology process level (the most bottom layer) to interplay interconnectivity and interoperability with its higher levels until the above pain points are addressed holistically. The chapter is going to focus mainly on the factory production of digital manufacturing and on describing the 3-Cs implementation plan, the enabling technology, and the achievable outcome ahead

Reaction study and phase formation in Bi2O3-ZnO-Nb2O5 ternary system

The formation of two structurally related phases; cubic pyrochlore and monoclinic zirconolite in Bi2O3-ZnO-Nb2O5 (BZN) ternary system was investigated. Phase pure Bi4Zn4/3Nb8/3O14 synthesized via conventional solid state methods at 950oC was refined and fully indexed with space group C2 /c; lattice parameters, a = 13.1109(3) Ǻ, b = 7.6764(2) Ǻ, c = 12.1528(2) Ǻ and α = γ = 90C and β = 101.33o, respectively. Reaction study revealed that Bi5Nb3O15 and BiNbO4 phases are two important precursors that react with ZnO at higher temperatures during phase formation. The pyrochlore does not form at the conventionally predicted composition Bi4Zn4/3Nb8/3O14, which falls in the zirconolite region. Instead, cubic pyrochlore forms at substantially lower Bi concentrations in BZN system. The two interrelated areas, a trapezoidal cubic pyrochlore subsolidus, and a rectangular shaped monoclinic zirconolite subsolidus serve to confirm the data consistency over various phase assemblages and compatibility in the phase diagram

Identification of 12 new susceptibility loci for different histotypes of epithelial ovarian cancer.

To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified nine new susceptibility loci for different EOC histotypes: six for serous EOC histotypes (3q28, 4q32.3, 8q21.11, 10q24.33, 18q11.2 and 22q12.1), two for mucinous EOC (3q22.3 and 9q31.1) and one for endometrioid EOC (5q12.3). We then performed meta-analysis on the results for high-grade serous ovarian cancer with the results from analysis of 31,448 BRCA1 and BRCA2 mutation carriers, including 3,887 mutation carriers with EOC. This identified three additional susceptibility loci at 2q13, 8q24.1 and 12q24.31. Integrated analyses of genes and regulatory biofeatures at each locus predicted candidate susceptibility genes, including OBFC1, a new candidate susceptibility gene for low-grade and borderline serous EOC

Numerical Analysis and Optimization of an Electromagnetic Micro-Generator for Vibration Energy Harvesting Applications

This work investigates the behavior of an electromagnetic micro-generator for power generation utilizing stray vibrations. The analysis is conducted through finite element simulations. The fundamental equations describing the performance of such devices are derived and the maximum power generation condition is discussed for the case of a cored winding structure

Energy harvesting autonomous sensor systems: design, analysis, and practical implementation

This book is the considered the first to describe sensor-oriented energy harvesting issues. Its content is derived from the author's research on the development of a truly self-autonomous and sustainable energy harvesting wireless sensor network (EH-WSN). This network harvests energy from a variety of ambient energy sources and converts it into electrical energy to power batteries. The book discusses various types of energy harvesting (EH) systems and their respective main components
