Essays on Manufacturers’ IT Capabilities for Digital Servitization
Over the last decades, studies have found that transformational drivers affect how firms innovate their business models (Chesbrough, 2010; Massa et al., 2016). In markets in which physical products become commodities, the servitization of business models is a transformational driver for firms (Wise & Baumgartner, 1999). For its part, digitalization increases the potential to reshape business models through novel use cases of technology (Yoo et al., 2010). Recently, digitalization was found to extend the opportunities from servitization through digital technologies as digital servitization (Paschou et al., 2020). Digital servitization describes a firm’s shift from product-centric offerings to service-centric offerings with the help of novel IT assets (Naik et al., 2020). The manufacturing industry provides promising examples of firms with portfolios of physical offerings that might undergo such a transformational shift (Baines et al., 2017).
So far, digital servitization research focuses primarily on four topics: re-defining the notion of servitization in the context of digitalization, identifying digital servitization value drivers, linking the transformation to specific technologies, and deriving how novel service offerings arise (Paschou et al., 2020; Zhou & Song, 2021).
Despite the breadth of digital servitization research, how firms can shift to service-centric offerings remains unclear (Kohtamäki et al., 2019). Specifically, research lacks studies on the prerequisites and mechanisms that link theory with evidence on achieving IT-enabled service innovation (Paschou et al., 2020). Further, how firms must organize to build and operate IT-enabled services around these technologies remains unclear (Paschou et al., 2020). In a recent report on the manufacturing industry, practitioners confirm these gaps and associate them with a lack of managerial and technical knowledge (Illner et al., 2020).
A theoretical lens that helps to address these shortcomings is the knowledge-based theory. It suggests that knowledge is the primary rationale, so that a firm benefits from its assets (Grant, 1996b; Nonaka, 1994). The knowledge-based theory understands a capability as a directed application of knowledge in a firm’s activities (Grant, 1996b; Nonaka, 1994). In the context of digitalization, firms require IT capabilities based on knowledge of how to capitalize on IT assets (Lee et al., 2015). Digital servitization research finds that IT capabilities are critical for identifying, adapting, and exploiting IT-enabled service innovations (Johansson et al., 2019). Still, little extant research informs firms that undergo digital servitization about which IT capabilities can help to strengthen their competitive advantage (Coreynen et al., 2017).
Even though IT capabilities may be necessary for success in innovating IT-enabled services, the required knowledge needs to be disseminated effectively throughout an organization (Foss et al., 2014; Grant, 1996a; Nonaka, 1994). The organizational control theory offers a theoretical perspective about knowledge dissemination mechanisms, which can be horizontal or vertical (Ouchi, 1979). Horizontal knowledge dissemination mechanisms depend on codifying processes in rules or measuring process outputs through indicators, while the locus of exerting these rules and indicators determines the vertical knowledge dissemination. The IT innovation and IT governance literature refers to these knowledge dissemination mechanisms as formalization of IT activities and centralization of IT decision-making (Weill, 2004; Winkler & Brown, 2013; Zmud, 1982). However, how to orchestrate knowledge, particularly for IT capabilities, in firms that undergo digital servitization is not yet clear (Kohtamäki et al., 2019; Münch et al., 2022; Sjödin et al., 2020).
Against this background, this dissertation addresses how manufacturers organize their IT capabilities while encountering the transformational drivers of digital servitization by answering the following overarching research question:

Computer Vision and Architectural History at Eye Level:Mixed Methods for Linking Research in the Humanities and in Information Technology
Information on the history of architecture is embedded in our daily surroundings, in vernacular and heritage buildings and in physical objects, photographs and plans. Historians study these tangible and intangible artefacts and the communities that built and used them. Thus valuableinsights are gained into the past and the present as they also provide a foundation for designing the future. Given that our understanding of the past is limited by the inadequate availability of data, the article demonstrates that advanced computer tools can help gain more and well-linked data from the past. Computer vision can make a decisive contribution to the identification of image content in historical photographs. This application is particularly interesting for architectural history, where visual sources play an essential role in understanding the built environment of the past, yet lack of reliable metadata often hinders the use of materials. The automated recognition contributes to making a variety of image sources usable forresearch.<br/

Revealing social dimensions of urban mobility with big data: A timely dialogue
Considered a total social phenomenon, mobility is at the center of intricate social dynamics in cities and serves as a reading lens to understand the whole society. With the advent of big data, the potential for using mobility as a key social analyzer was unleashed in the past decade. The purpose of this research is to systematically review the evolution of big data's role in revealing social dimensions of urban mobility and discuss how they have contributed to various research domains from early 2010s to now. Six major research topics are detected from the selected online academic corpuses by conducting keywords-driven topic modeling techniques, reflecting diverse research interests in networked mobilities, human dynamics in spaces, event modeling, spatial underpinnings, travel behaviors and mobility patterns, and sociodemographic heterogeneity. The six topics reveal a comprehensive, research-interests, evolution pattern, and present current trends on using big data to uncover social dimensions of human mobility activities. Given these observations, we contend that big data has two contributions to revealing social dimensions of urban mobility: as an efficiency advancement and as an equity lens. Furthermore, the possible limitations and potential opportunities of big data applications in the existing scholarship are discussed. The review is intended to serve as a timely retrospective of societal-focused mobility studies, as well as a starting point for various stakeholders to collectively contribute to a desirable future in terms of mobility

Operational modal analysis and prediction of remaining useful life for rotating machinery
This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonThe significance of rotating machinery spans areas from household items to vital industry sectors, such as aerospace, automotive, railway, sea transport, resource extraction, and manufacturing. Hence, our technologised society depends on efficient and reliable operation of rotating machinery. To contribute to this aim, this thesis leverages measurable quantities during its operation for structural-mechanical evaluation employing Operational Modal Analysis (OMA) and the prediction of Remaining Useful Life (RUL). Modal parameters determined by OMA are central for the design, test, and validation of rotating machinery. This thesis introduces the first open parametric simulation dataset of rotating machinery during an acceleration run. As there is a lack of similar open datasets suitable for OMA, it lays a foundation for improved reproducibility and comparability of future research. Based on this, the Averaged Order-Based Modal Analysis (AOBMA) method is developed. The novel addition of scaling and weighted averaging of individual machine orders in AOBMA alleviates the analysis effort of the existing Order-Based Modal Analysis (OBMA) method by providing a unified set of modal parameters with higher accuracy. As such, AOBMA showed a lower mean absolute relative error of 0.03 for damping ratio estimations across compared modes while OBMA provided an error value of 0.32 depending on the processed order. At excitation with high harmonic contributions, AOBMA also resulted in the highest number of accurately identified modes among the compared methods. At a harmonic ratio of 0.8, for example, AOBMA identified an average of 11.9 modes per estimation, while OBMA and baseline OMA followed with 9.5 and 9 modes, respectively. Moreover, it is the first study, which systematically evaluates the impact of excitation conditions on the compared methods and finds an advantage of OBMA and AOBMA over traditional OMA regarding mode shape estimation accuracy. While OMA can be used to evaluate significant structural changes, Machine Learning (ML) methods have seen substantially greater success in condition monitoring, including RUL prediction. However, as these methods often require large amounts of time and cost-
intensive training data, a novel data-efficient RUL prediction methodology is introduced, taking advantage of distinct healthy and faulty condition data. When the number of training sequences from an open dataset is reduced to 5%, an average prediction Root Mean Square Error (RMSE) of 24.9 operation cycles is achieved, outperforming the baseline method with an RMSE of 28.1. Motivated by environmental considerations, the impact of data reduction on the training duration of several method variants is quantified. When the full training set is
utilised, the most resource-saving variant of the proposed approach achieves an average training duration of 8.9% compared to the baseline method
