Metrology is part of the essential but largely hidden infrastructure of the modern world. This book concentrates on the infrastructure aspects of metrology. It introduces the underlying concepts: International system of units, traceability and uncertainty; and describes the concepts that are implemented to assure the comparability, reliability and quantifiable trust of measurement results. It is shown what benefits the traditional metrological principles have in fields as medicine or in the evaluation of cyber physical systems.

Speech enhancement is a classical problem in signal processing, yet still largely unsolved. Two of the conventional approaches for solving this problem are linear filtering, like the classical Wiener filter, and subspace methods. These approaches have traditionally been treated as different classes of methods and have been introduced in somewhat different contexts. Linear filtering methods originate in stochastic processes, while subspace methods have largely been based on developments in numerical linear algebra and matrix approximation theory.

This book bridges the gap between these two classes of methods by showing how the ideas behind subspace methods can be incorporated into traditional linear filtering. In the context of subspace methods, the enhancement problem can then be seen as a classical linear filter design problem. This means that various solutions can more easily be compared and their performance bounded and assessed in terms of noise reduction and speech distortion. The book shows how various filter designs can be obtained in this framework, including the maximum SNR, Wiener, LCMV, and MVDR filters, and how these can be applied in various contexts, like in single-channel and multichannel speech enhancement, and in both the time and frequency domains.

Corrosion is a high-cost and potentially hazardous issue in numerous industries. The potential use of diverse carbon nanoallotropes in corrosion protection, prevention and control is a subject of rising attention. This book covers the current advancements of carbon nanoallotropes in metal corrosion management, including the usage of nanostructure materials to produce high-performance corrosion inhibitors and corrosion-resistant coatings.

Principles of Economics and Management for Manufacturing Engineering combines key engineering economics principles and applications in one easy to use reference. Engineers, including design, mechanical, and manufacturing engineers are frequently involved in economics-related decisions, whether directly when selecting materials or indirectly when managers make order quantity decisions based on their work. Having a knowledge of the management and economic activities that touch on engineering work is a core part of most foundational engineering qualifications and becomes even more important in industry. Covering a wide range of management and economic topics from the point-of-view of an engineer in industry, this reference provides everything needed to understand the commercial context of engineering work.
