Calculations of critical misfit and thickness: An overview
This overview stresses the equilibrium/nonequilibrium nature of the physical properties, as well as the basic properties of the models, used to calculate critical misfit and critical thickness in epitaxy
Big Data and the Internet of Things
Advances in sensing and computing capabilities are making it possible to
embed increasing computing power in small devices. This has enabled the sensing
devices not just to passively capture data at very high resolution but also to
take sophisticated actions in response. Combined with advances in
communication, this is resulting in an ecosystem of highly interconnected
devices referred to as the Internet of Things - IoT. In conjunction, the
advances in machine learning have allowed building models on this ever
increasing amounts of data. Consequently, devices all the way from heavy assets
such as aircraft engines to wearables such as health monitors can all now not
only generate massive amounts of data but can draw back on aggregate analytics
to "improve" their performance over time. Big data analytics has been
identified as a key enabler for the IoT. In this chapter, we discuss various
avenues of the IoT where big data analytics either is already making a
significant impact or is on the cusp of doing so. We also discuss social
implications and areas of concern.Comment: 33 pages. draft of upcoming book chapter in Japkowicz and Stefanowski

A model to assess customer alignment through customer experience concepts
Business and Information Technology Alignment (BITA) has been one of the main
concerns of IT and Business executives and directors due to its importance to
overall company performance, especially today in the age of digital
transformation. For BITA has been developed several models which in general has
focused in the implementation of alignment strategies for the internal
operation of the organizations and in the measurement of this internal
alignment, but, there is still a big gap in measurement models of the alignment
with the external environment of the organizations. In this paper is presented
the design and application of a maturity measurement model for BITA with the
customers, where the customers are actors of the external environment of the
companies. The proposed model involves evaluation criteria and business
practices which the companies ideally do for improve the relationship with
their customers.Comment: 12 pages, Preprint version, BIS 2019 International Workshops,

Addressing decision making for remanufacturing operations and design-for-remanufacture
Remanufacturing is a process of returning a used product to at least original equipment manufacturer original performance specification from the customers' perspective and giving the resultant product a warranty that is at least equal to that of a newly manufactured equivalent. This paper explains the need to combine ecological concerns and economic growth and the significance of remanufacturing in this. Using the experience of an international aero-engine manufacturer it discusses the impact of the need for sustainable manufacturing on organisational business models. It explains some key decision-making issues that hinder remanufacturing and suggests effective solutions. It presents a peer-validated, high-level design guideline to assist decision-making in design in order to support remanufacturing. The design guide was developed in the UK through the analysis of selections of products during case studies and workshops involving remanufacturing and conventional manufacturing practitioners as well as academics. It is one of the initial stages in the development of a robust design for remanufacture guideline
Design for Product Service Supportability (DfPSS) Approach: A State of the Art to Foster Product Service System (PSS) Design
Product-Service System lifecycle is characterized by several phases from the initial concept to the final disposal. However, as for conventional products, the profit generation and the market success of PSSs critically depend on the decisions taken during the initial lifecycle stages, when PSSs are conceptualized, designed, developed and engineered. These are hence the phases deserving more attention in order to manage the intrinsic complexity of such systems, taking it in account during the entire PSS life cycle design phase. According to this, one of the main gaps detected in the PSS design process is the lack of methods able to support the early integration of service features during the product design. In this specific context DfX approaches, where X= x-bility stands for enhancing products design considering at the same time service features to be embedded on it (x) according to certain performance measures (-bility), are supposed to significantly contribute. The Serviceability point of view appears to be a critical aspect of the design of product-oriented PSS that has not been improving yet: significant enhancement in this products' characteristic will only occur if some changes will arise in the way they are designed. Indeed companies still need guidelines able to enhance the PSS design process in a more systematic way. On this basis, due to the main gap of integrating service features in the product design process, the paper presents and defines DfX approaches enlightening, among the several target properties they have been called to improve so far, the most suitable DfX streams detected to solve the reported PSS design issue and to define Design for Product Service Supportability (DfPSS)
Design of Product Service Systems at the Base of The Pyramid
Abstract in UndeterminedThe Base of the Pyramid (BoP) consists of about two-fifths of the world population. This population can be categorized as poor with income of less than 2 dollars per day. It is important to alleviate poverty. One of the promising approaches to tackle the wicked problem of poverty is business development combined with poverty alleviation. In this approach, integrated solutions are necessary in order to address the diverse issues in the BoP. These integrated solutions are in the form of product service systems (PSS) rather than the conventional product-oriented or service-oriented solutions. In this paper, we explore different issues that need to be addressed in the PSS design at the BoP. We have also explored strategies used in this PSS design. We have used a case study to explain these issues and strategies. In addition, we have identified salient characteristics of the PSS design at the BoP
Value and servitization; Creating complex deployed responsive services
This paper presents a value framework which captures how manufacturing engineering firms are transforming from product to complex service provision where the service is delivered within the customer’s dynamic environment and their ability to capture worth is determined by the success of their customer.Key points:1.A value framework presents the business models for service transformation which requires managers to consider and capture their value proposition, value realisation and worth capture processes2.A characterisation of a particular form of service, named complex deployed responsive services [CDRS]3.CDRS are delivered in partnership with customers, realised off-site and in the customer’s environment and must be responsive to their demands such that their success determines the success of the provider.4.Application of the value framework to a number of business-to-business CDRS has demonstrated its utility in identification and understanding of opportunities for worth capture5.The proposed framework helps firms consider how to avoid value slippage, which is the process where the value creator is unable to capture the worth from their effort
