Purpose This paper aims to explore the effect of subsidiary autonomy on knowledge transfers during captive offshoring to emerging markets. Design/methodology/approach Five longitudinal cases of captive R&D and manufacturing offshoring to emerging markets. Findings The propositions entail the dual effect of operational subsidiary autonomy on primary knowledge transfer and reverse knowledge transfer. For newly established subsidiaries, operational subsidiary autonomy has a mainly negative effect on primary knowledge transfer and a mainly positive effect on reverse knowledge transfer and local collaboration activities increase this effect. Strategic subsidiary autonomy is mainly negative for primary and reverse knowledge transfer. Research limitations/implications Limitations concerning the applied exploratory case study approach suggest that further research should test the identified relationships using surveys, after the initial pilot study. Practical implications A gradual increase of operational subsidiary autonomy as the subsidiary capability level increases is beneficial to ensure primary knowledge transfer. Allowing subsidiaries to collaborate locally within the confines of their mandates benefits reverse knowledge transfer. Originality/value This paper extends the secondary knowledge transfer concept to include knowledge flows with local collaboration partners, not only other subsidiaries and clarifies the distinction between operational and strategic autonomy concerning local collaboration. A subsidiary asserts operational autonomy when its collaboration with local partners relates to its existing mandate. A subsidiary asserts strategic autonomy when it collaborates with local partners beyond this mandate.

Purpose The purpose of this paper is twofold: to study the relationship between reverse knowledge transfer (RKT) and headquarters’ innovation, examining potential moderators of such relationship, and to analyze the role of headquarters’ absorptive capacity (AC) and the coordination mechanisms they adopt as antecedents of RKT. Design/methodology/approach Quantitative data were collected from 104 Spanish multinational companies. Structural equation modeling was used to test hypotheses. Findings Findings provide the evidence of a positive relationship between RKT and headquarters’ innovation. This relationship is higher when the knowledge transferred from subsidiaries to parent units is of a more tacit nature, and also when the organizational distance between them is larger. The results also show that the parent unit’s AC and the use of mechanisms for coordinating company units can facilitate RKT. Practical implications MNCs that wish to be more innovative should be aware that it is worth the effort of fostering RKT, especially when knowledge is more tacit and comes from subsidiaries with different organizational practices and culture because these two variables increase the positive relationship that it was found between effective RKT and the development of innovation in the headquarters. Additionally, results show that in order to facilitate RKT, the improvement of headquarters’ AC and the use of mechanisms of coordination between them and its subsidiaries can be useful. Originality/value Up to the authors’ knowledge, this is the first empirical study that examines the link between RKT and headquarters innovation, and one of the few that focuses on headquarters characteristics as determinants of RKT. Thus, the findings contribute to the literature that highlights the benefits of RKT for MNC’s competitiveness, and that seeks to know how to promote RKT.

Reverse knowledge transfer refers to the knowledge flow from the subsidiaries to the parent companies. The paper analyzes if the subsidiaries located in former transitional country (Slovakia) can create and transfer original knowledge to the parent companies in so-called developed Western Europe and focuses on the drivers, communication channels and contributions of such a knowledge flow for both, the headquarters and the subsidiaries. Qualitative research of four subsidiaries of multinational corporations was conducted to identify reverse knowledge transfers and to study them in-depth using case study method.

Purpose – This study aims to provide insight to the little-researched phenomenon of reverse knowledge flow within multinational corporations (MNCs) and to explain the role of managerial attention in exploiting the prospect of knowledge transfer from subsidiaries located in developing countries. Design/methodology/approach – Existing literature across disciplines has been integrated to provide a clear description of the concept of reverse knowledge flow and managerial attention, in order to explain the role of managerial attention in reverse knowledge transfer activities within MNCs. Two pilot studies were conducted on European MNCs to build the background for this study. Findings – Managerial attention is a key factor in recognising potential source of knowledge within the multinational network, and a prior requirement for knowledge transfer to take place. Attention decisions are partially based on the knowledge source location, awareness/attractiveness, and the strategic importance. Thus, MNCs can adopt managerial practices and control mechanisms to influence the attention of executives and achieve higher knowledge flow from subsidiaries. Research limitations/implications – There is a need to undertake empirical research and in-depth case studies of knowledge management practices using the arguments and framework provided in this article. Practical implications – MNCs can develop mechanisms for overcoming attention biases influence on reverse knowledge flow. The attention based approach can lead to better subsidiary integration and knowledge management practices in MNCs. Originality/value – This study advances the theory on reverse knowledge flow in MNCs by presenting an attention based theoretical framework for effective knowledge transfer.

Full textAbstract:
Knowledge is a source of competitive advantage which strengthens multinational corporations’ (MNCs) market position, and thus they set up overseas subsidiaries partly to access other firms’ knowledge which resides in local markets. From the MNC viewpoint, overseas subsidiaries have a chance to access local market information (LMI), develop new competences themselves and share this information with their headquarters; thereby contributing to the formation of MNCs’ competitive advantage. This study posits that the extent to which overseas subsidiaries reversely transfer local information is influenced by their knowledge transfer capacity and relational capital, both of which enhance the learning environment which facilitates the knowledge exchange process. In this context, the research objective is to identify the effects of factors encompassing knowledge transfer capacity and relational capital on the reverse transfer of LMI from subsidiaries within MNC networks. In addition, this study also tries to examine the different influences of those determinants on different sizes of organisation. Although study on reverse knowledge transfer (RKT) from subsidiaries to its headquarters is becoming increasingly prominent, the debate discussing the key determinants which affect it has not reached an academic consensus. By integrating both knowledge transfer capacity and relational capital as overarching theoretical lenses and exploring cause-and-effect relationships, this study fills certain extant research gaps. A conceptual framework is developed and then it is investigated empirically, using a sample of 432 subsidiaries operating in the Korean market. OLS regression and Spearman rank order correlation coefficients are used to interrogate the data. The OLS regressions find that knowledge development capability, subsidiary willingness and autonomy are critical factors affecting RKT within MNC networks. Both socialisation mechanisms and trust are the primary facilitators of relational capital between subsidiaries and MNCs and extend RKT from the former to the latter. In addition, the key drivers for RKT for large-sized subsidiaries are knowledge development capability, subsidiary autonomy and trust. For medium-sized subsidiaries, the key drivers are subsidiary willingness, trust and organisational distance. For small-sized subsidiaries, the key drivers of RKT are knowledge development capability, subsidiary autonomy and socialisation mechanisms. Based on the results, the contributions of this study are three-folds. First, the research identifies what determines RKT from subsidiaries to MNCs in the Korean context. Second, in doing so, it corporates both the relational capital and knowledge transfer capacity perspectives. Thus, it theoretically contributes to those perspectives. Third, it also elucidates the effect of organisational size on RKT.

Recent contributions highlight the importance of international knowledge transfer as a fundamental source of competitive advantage of MNCs. Due to the traditional assumption that parent firms are the prime source of knowledge, majority of studies have focused on knowledge transfer from headquarters to subsidiaries. However, the role of subsidiaries within MNCs has changed dramatically; many subsidiaries have gained a creative role by generating new resources depending on the comparative advantage of the location in which they operate, and through the process of reverse knowledge transfer, they subsequently contribute to the competence upgrading of the MNC. In reviewing the extant literature on MNC knowledge transfer and in particular reverse knowledge transfer, this research unleashes several gaps, notably in the understanding of factor affecting subsidiary knowledge development and reverse knowledge transfer within the service sector. Borrowing concepts from the knowledge-based and network views, a series of hypotheses were tested using the result of a web-based survey of the subsidiaries that were located in the UK, had a non-UK parent firm, and were active in the KIBS sector. Responses from 187 general managers, managing directors, or chief executives of subsidiaries confirm that those subsidiaries that develop and maintain business relationships with their internal (sister subsidiaries and headquarters) and external actors (customers, universities, suppliers, competitors) and have high level of autonomy are more capable of developing knowledge. With regards to determinants of reverse knowledge transfer, while subsidiary characteristics (knowledge development and willingness) and relationship characteristics (socialization mechanisms) are emerged as the main facilitators of reverse knowledge transfer, knowledge characteristics (tacitness and complexity) appeared as the main hindrances of this phenomenon. Moreover, the results indicate that, (a) socialisation mechanisms augment the extent of shared values and subsidiary-parent firm embeddedness and (b) willingness mediates the impacts of shared values and subsidiary-parent firm embeddedness on reverse knowledge transfer. The key contributions of this research are two-fold: firstly, it examines the process of reverse knowledge transfer and knowledge development exclusively within the KIBS sector. Secondly, it investigates the joint impacts of relationship characteristics, knowledge characteristics, and subsidiary (sender) characteristicson reverse knowledge transfer.

Recently, facing the fierce competition around the world, the headquarters of many MNCs are under pressure to make a decision quickly and effectively for their global marketing strategy. Under such a situation, how effectively the headquarters can obtain knowledge regarding the market situation of subsidiaries around the world is important. In this research, the concept of reverse knowledge transfer is applied to the space of the headquarters' acquisition of knowledge from subsidiaries, from the perspective of decision-making for global marketing strategies. In the extant literature, however, studies on reverse knowledge transfer analyzing the mechanisms dynamically in a multi-faceted way from the perspective of transferring marketing-related knowledge are rare. In order to capture the reverse knowledge transfer mechanisms in a MNC precisely and dynamically, three case studies of the headquarters of an American MNC and its Japanese subsidiary were conducted. Through analysis of the case studies, two new factors were found; one is 'bypass effect', and the other is 'heeding capacity'. By bringing in those new factors, a new dynamic model for reverse knowledge transfer is proposed.

A transferência de conhecimento internacional é fonte fundamental de vantagem competitiva das empresas multinacionais. Em razão do pressuposto tradicional de que a matriz da multinacional é a principal fonte de conhecimento, a maioria dos estudos tem-se centrado na transferência de conhecimento da matriz para as subsidiárias. Entretanto, a importância estratégica da subsidiária tem crescido nas últimas dédadas, em razão de seus recursos e de suas capacidades que podem contribuir ativamente para a geração de valor e o subsequente ganho de vantagem competitiva para toda a corporação multinacional. Este estudo investiga os fatores determinantes da transferência de conhecimento tecnológico que parte da subsidiária para a matriz (transferência reversa), em empresas multinacionais brasileiras, procurado integrar as contribuições da visão baseada no conhecimento e da teoria das redes. Para testar os pressupostos, foi conduzido um survey eletrônico com 78 subsidiárias, de um universo de 240 subsidiárias no exterior em 63 empresas multinacionais brasileiras. O método para a análise dos dados foi a modelagem de equações estruturais com estimação partial least esquare. Os resultados mostram que, ainda que em média extensão, as subsidiárias brasileiras transferem conhecimento tecnológico para a matriz, sobretudo os relacionados a produtos. Com relação aos fatores determinantes da transferência reversa de conhecimento tecnológico, os associados positivamente foram: características do conhecimento (complexidade), características das subsidiárias (ambiente institucional, autonomia e integração externa com os fornecedores) e características da interação matriz/subsidiárias (integração interna com a matriz e mecanismos de socialização via comunicação pessoal). O único fator associado negativamente foi a integração externa com instituições de C&T. Conclui-se que a matriz precisa elaborar uma estratégia de compartilhamento de conhecimento interno, a fim de motivar e incentivar, de forma deliberada, o fluxo do conhecimento gerado nas subsidiárias. Por sua vez, as subsidiárias devem tornar claro aos seus funcionários, os benefícios de melhorar a eficácia da transferência de conhecimento para, inclusive, melhorar seu posicionamento estratégico dentro da rede corporativa.Knowledge transfer is key source of international competitive advantage of multinational companies. Due to the traditional assumption that the headquarter of the multinational is the main source of knowledge, most studies have focused on the transfer of knowledge from headquarters to subsidiaries. However, it has grown considerably in recent times the strategic importance of subsidiary, due to their resources and capabilities that can actively contribute to the generation of value and the subsequent gain of competitive advantage for the entire multinational corporation. This study investigates the determinants of technological knowledge transfer from the subsidiary to the parent company in Brazilian multinational companies, and sought to integrate the contributions of vision of the knowledge-based and networks theory. To test the assumptions we carried out an electronic survey with 78 subsidiaries, of a universe of 240 overseas subsidiaries from 63 Brazilian multinationals. The method of data analysis was the structural equation modeling with Partial Least Esquare Estimation. The results show that the Brazilian subsidiaries knowledge transfer to the headquarter, although in medium extent. Regarding the determinants of technological knowledge reverse transfer, the positive factors: characteristics of knowledge (complexity), characteristics of subsidiaries (location-specific factors, external integration with the supplier\'s chain and autonomy) and characteristics of the interaction headquarter/subsidiaries (headquarter integration and socialization mechanisms). The only negative factor was the external integration with Science and Technology Research. We conclude that the headquarter may need to develop a strategy for internal knowledge sharing, in order to motivate and encourage deliberately knowledge flow generated at the subsidiaries. In the order hand, the subsidiaries should make clear the benefits of improving the effectiveness of knowledge transfer improve its strategic position within the corporate network.

Full textAbstract:
Emerging-market multinational enterprises (EMNEs) have been increasingly engaged in outward foreign investments, the distinctive feature for their internationalization being the aim of strategic asset-seeking and acquiring knowledge. Thus, reverse knowledge transfer is significant in achieving innovation catch-up. Subsidiary willingness towards reverse knowledge transfer has huge implications for building up competitive advantages for MNEs. However, research on EMNEs shows that the subsidiary willingness towards reverse knowledge transfer is rather low. In this vein, the purpose of this thesis is to explore headquarters initiatives to improve subsidiary willingness in EMNEs. This thesis conducts a qualitative case study by semi-structured interviews with respondents from both headquarters and subsidiaries in a Chinese MNE. A case of a Chinese MNE, Geely, and its two Swedish subsidiaries (i.e. Volvo Cars and CEVT) is adopted to explore our research question. The findings suggest that headquarters in EMNEs can improve subsidiary willingness towards reverse knowledge transfer by promoting socialization between headquarters and subsidiary, granting subsidiary autonomy, making contributions to the subsidiary as well as maintaining headquarters/subsidiary cooperation. This thesis contributes to the research on reverse knowledge transfer and EMNEs by identifying new antecedents which influence subsidiary willingness in EMNEs.

O conhecimento é uma importante fonte de vantagem competitiva e a principal razão para a internacionalização de empresas. Com a intensificação do interesse das empresas multinacionais (EMNs) pelos países em desenvolvimento, evidenciado pelo aumento do Investimento Direto Estrangeiro (IDE) em nações emergentes, as subsidiárias adquiridas aumentam sua importância estratégica na rede da multinacional, pois detém conhecimentos que oportunizam a criação de vantagens competitivas. (ANDERSSON; DELLESTRAND; PEDERSEN, 2014). Contudo, a transferência reversa de conhecimento, cujo fluxo ocorre no sentido da subsidiária para a matriz, ainda apresenta desafios singulares na gestão das EMNs. (FOSS; HUSTED; MICHAILOVA, 2010). No presente estudo buscou-se analisar o processo de transferência reversa de um conhecimento gerado em uma subsidiária brasileira e transferido para a matriz de uma corporação norte americana. Por meio de um estudo de caso único, os dados foram coletados em análise documental, observação in loco e entrevistas com diversos gestores nos Estados Unidos e nas subsidiárias do Brasil e do México. Após, os dados foram triangulados com a técnica de análise de conteúdo. Os resultados indicam a existência de transferência reversa de conhecimento de forma não explícita, corroborando os estudos nesta área. Entretanto, durante o mapeamento dos processos, perceberam-se singularidades no caso estudado, como a motivação e o esforço da subsidiária para ser reconhecida pelo conhecimento gerado e a caracterização de atores envolvidos no processo que não são abordados na literatura.
Knowledge is an important source of competitive advantage and the main reason for the internationalization of companies. With the increasing interest of multinational companies (MNEs) in developing countries, evidenced by the increase in Foreign Direct Investment (FDI) in emerging nations, the acquired subsidiaries increase their strategic importance in the network of the multinational, since it has knowledge that allows the creation of competitive advantages. (ANDERSSON; DELLESTRAND; PEDERSEN, 2014). However, the reverse knowledge transfer, which flows from the subsidiary to the parent company, still presents unique challenges in the management of MNCs. (FOSS; HUSTED; MICHAILOVA, 2010). The present study aimed to analyze the process of reverse transfer of a knowledge generated in a Brazilian subsidiary and transferred to headquarter of a North American corporation. Through a single case study, the data were collected in documentary analysis, in situ observation and interviews with several managers in the United States headquarter and in the Brazilian and Mexican subsidiaries. Afterwards, the data were triangulated with the technique of content analysis. The results indicate the existence of a reverse transfer of knowledge in a non-explicit way, corroborating the studies in this area. However, during the process mapping, singularities were perceived in the case studied, such as the motivation and effort of the subsidiary to be recognized by the knowledge generated and the characterization of actors involved in the process that are not addressed in the literature.

This work investigates the phenomenon of the reverse transfer of knowledge in subsidiaries with a multidimensional approach. The main objective is to verify in an empirical way if the strategies and actions of marketing, autonomy and integration of marketing has influence in the reverse knowledge transfer in the foreign multinationals enterprises located in Brazil. As control it was verify the time of international experience and the type of industry can be influence the reverse knowledge transfer. To test the hypotheses, a survey was conducted with managers of 104 subsidiaries of foreign multinationals located in Brazil. The data were analyzed by multiple linear regression and cluster analysis. To deepen the analysis, the empirical part also includes qualitative exploratory research through of the multiple case study with three subsidiaries of foreign multinationals. The results in both empirical researches show that product innovation and the integration between subsidiary and headquarter have a positive effect on the reverse knowledge transfer. This study contributes for academic paradox showing elements to the view of authors and refutes other theoretical perspectives, such as Rugman (2009), Narula (2006), Dunning (1988) and Dunning and Narula (1996) and Ghauri et al (2016) and Yip (1995). Managerially, this work deepens the factors that determine the reverse knowledge transfer like the development of innovations and the high integration between subsidiary and headquarter. Exposing to managers the importance of managing communication with the headquarter and to invest in human resources with creativity and innovation capacity. Also, it became evident that the marketing operations of foreign multinationals in Brazil are developed in the same time between subsidiary and headquarter. The results are expected to contribute to the extension of international marketing literature and provides a better understanding of the phenomenon of reverse knowledge transfer in the brazilian context.
Este trabalho investiga o fenômeno da transferência reversa de conhecimento em subsidiárias com uma abordagem multidimensional. O objetivo principal é verificar de modo empírico se as estratégias e ações de marketing, a autonomia e a integração de marketing influenciam na transferência reversa de conhecimento em multinacionais estrangerias no Brasil. Como controle verifica-se se o tempo de experiência internacional e o tipo de indústria influenciam na transferência reversa de conhecimento. Para testar as hipóteses apresenta-se uma survey com gestores de 104 subsidiárias de multinacionais estrangeiras localizadas no Brasil. Os dados foram analisados por meio de regressão linear múltipla e análise de conglomerados. Para aprofundar as análises, a parte empírica inclui também pesquisa qualitativa exploratória realizada por meio de estudo de caso múltiplo realizada com três subsidiárias de multinacionais estrangeiras. Os resultados em ambas pesquisas empíricas demostram que inovação de produto e a integração entre subsidiária e matriz possuem efeito positivo na transferência reversa de conhecimento. No que se refere a paradoxo acadêmico, este estudo contribui sustentando a visão de autores e refutando outras óticas teóricas, como Rugman (2009), Narula (2006), Dunning (1988) e Dunning e Narula (1996) e Ghauri et al (2016) e Yip (1995). Gerencialmente, este trabalho aprofunda os fatores que determinam a transferência reversa de conhecimentos, o desenvolvimento de inovações e a alta integração com a matriz. Expondo aos gestores a importância de gerir a comunicação com a matriz e investir em recursos humanos com criatividade e capacidade de inovação. Ainda, ficou evidente que as operações de marketing de multinacionais estrangeiras no país são desenvolvidas de forma dividida entre matriz e subsidiária. Espera- se com os resultados contribuir para a extensão da literatura de marketing internacional e para uma melhor compreensão acerca do fenômeno transferência reversa de conhecimento no contexto brasileiro.

JEL classification: F23, L16Knowledge transfer, specifically reverse knowledge transfer (RKT) from invested European company to company from emerging markets, has become well-taken strategy for enhancing company’s competitive advantage and become an important topic for academic research. Since 2010, a trend is confirmed that Chinese multinational enterprises (MNEs) employ outbound direct investment (ODI) as a strategy to acquire knowledge and realize industrial upgrading. Tacit knowledge is found out as most valuable asset to company, thus it is also the most difficult in transferring. This research is carried out with specific focus on tacit knowledge transfer to Chinese investor companies. The result of RKT does not always meet investor-company’s expectation. Built on “knowledge sender-receiver” model and the theory of ba, I try to explore a mechanism for better RKT performance after Chinese MNEs invested in Europe. A combination of qualitative and quantitative methodology is applied in this research. In the end, 10 interviews and 101 questionnaires are collected among employees who work at Chinese MNEs or invested European companies that have actively involved in ODI for knowledge transfer. RKT performance is impacted by complex factors. As an explorative research, we have found that firms’ absorptive capacity, under the environment of high-employeecommitted organizational climate, trust in leadership and other RKT participants, wellestablished formal knowledge transmission channel and similar organizational structure in both Chinese MNEs and invested European companies have major impact on reverse knowledge transfer performance.
A transferência de conhecimento, nomeadamente a Transferência Inversa de Conhecimento (TIC) de empresas europeias adquiridas para empresas de economias emergentes, tornou-se numa estratégia adotada para melhorar a vantagem competitiva e é também um tópico importante de pesquisa académica. Desde 2010 que as empresas multinacionais chinesas utilizam o investimento no exterior como uma estratégia de aquisição de conhecimento para efetuar a atualização industrial. O conhecimento tácito é considerado não somente como o ativo mais importante de uma empresa como também o mais difícil de transferir. Esta investigação focaliza-se na transferência do conhecimento tácito das empresas europeias para as empresas chinesas que nelas investiram. O resultado da transferência nem sempre satisfaz as expetativas das empresas investidoras. Baseando-me no modelo “emissor-recebedor de conhecimento” e na teoria do ba, tentei explorar um mecanismo para uma melhor Transferência Inversa de Conhecimento para as multinacionais chinesas que investiram na Europa. Nesta investigação utilizamos uma combinação de métodos qualitativos e quantitativos. Para além de 10 entrevistas recolhemos também 101 questionários de colaboradores de empresas multinacionais que investiram na Europa e que estão envolvidos na transferência inversa de conhecimento. A transferência inversa de conhecimento está sujeita a fatores muito complexos. Nesta investigação exploratória, concluímos que a capacidade de absorção, num ambiente de elevado empenhamento, confiança na liderança e nos outros participantes na TIC, canais de transmissão bem organizados e estruturas organizacionais semelhantes têm um grande impacto da transferência inversa de conhecimento.

Full textAbstract:
Multinational organizations are global knowledge transfer systems where multiple knowledge flows happen simultaneously between HQ, local clusters, and subsidiaries. HQs are irreplaceable sources of knowledge for the subsidiaries, since they possess valuable intangible assets and capabilities, used in the local markets. On the other hand, the local knowledge transferred from the subsidiaries to the HQs benefits the multinational's productivity and local performance, improving the formulation of global strategies, facilitating the access to external resources and supporting on R&D and NPD activities. The goal of this chapter is to deepen the literature on reverse knowledge transfers in which knowledge flows from the subsidiary to the HQ. This chapter seeks to explore the key success factors that influence reverse knowledge transfers within multinationals. It categorizes knowledge transfers within three groups: subsidiary's characteristics, knowledge characteristics and relationship between HQ and subsidiary. The chapter also aims to explain the outcomes of these knowledge flows.

Full textAbstract:
Current mechanisms for knowledge transfer in deep networks tend to either share the lower layers between tasks, or build upon representations trained on other tasks. However, existing work in non-deep multi-task and lifelong learning has shown success with using factorized representations of the model parameter space for transfer, permitting more flexible construction of task models. Inspired by this idea, we introduce a novel architecture for sharing latent factorized representations in convolutional neural networks (CNNs). The proposed approach, called a deconvolutional factorized CNN, uses a combination of deconvolutional factorization and tensor contraction to perform flexible transfer between tasks. Experiments on two computer vision data sets show that the DF-CNN achieves superior performance in challenging lifelong learning settings, resists catastrophic forgetting, and exhibits reverse transfer to improve previously learned tasks from subsequent experience without retraining.

Full textAbstract:
Knowledge of the effects of inlet velocity and inlet equivalence ratio fluctuations on the rate of heat release in lean premixed gas turbine combustors is essential for predicting combustor instability characteristics. This information is typically obtained from independent velocity-forced and fuel-forced flame transfer function measurements, where the global chemiluminescence intensity is used as a measure of the flame’s overall rate of heat release. The flame in an actual lean premixed combustor is referred to as a technically premixed flame and is exposed to both velocity and equivalence ratio fluctuations. Under these conditions the chemiluminescence intensity does not provide a reliable measure of the flame’s rate of heat release. The objective of this work is to experimentally assess the validity of a technique for making heat release rate measurements in technically premixed flames based on the linear superposition of fuel-forced and velocity-forced flame transfer function measurements. In the absence of a technique for directly measuring the heat release rate fluctuations in an air-forced technically premixed, the heat release reconstruction is validated indirectly by comparing measured to reconstructed chemiluminescence intensity fluctuations. Results are reported for a range of operating conditions and forcing frequencies which demonstrate the capabilities and limitations of this technique. A variation of this technique, referred to as a reverse reconstruction, is proposed which does not require a measurement of the fuel-forced flame transfer function. The air-forced flame transfer function gain and phase obtained using the reverse reconstruction technique are presented and compared to the results from the direct reconstruction technique.

The performance of heat exchangers degrades with time due to fouling or deposition of material on the heat transfer surface. The fouling of critical exchangers in manufacturing plants results in a significant cost impact in terms of production losses, energy efficiency, and maintenance costs. While most plants monitor their exchangers to some degree, the ability to effect real and sustainable improvements requires four components: (1) real time monitoring; (2) an advance warning mechanism; (3) the ability to diagnose the cause of fouling; and (4) the ability to treat the cause in order to slow or reverse the degradation. CHeX is a comprehensive tool which monitors, predicts, and diagnoses heat exchanger performance. The unique features of this advanced technology include: numerous data cleaning steps to improve data quality and isolate a net fouling trend, an adaptive model which learns from the past to predict performance three years in advance, and knowledge-based diagnostics which identify the probable cause(s) of fouling and recommend corrective actions. The final control action is performed by a field engineer in adjusting the fouling treatment. The scope of the current paper includes only the detection and prediction features. To date, CHeX has been validated at three chemical processing plants, for fourteen exchangers. Selected case studies shall be presented to demonstrate the power of its algorithms over traditional calculations.

A bench-top educational system, the Adaptive Water Treatment for Education and Research (WaTER) Laboratory, has been developed as part of a year-long capstone design project. The Adaptive WaTER Lab teaches students about the effectiveness of various water purification techniques. Stackable housings employ six different filtration and purification methods including: sediment filtration, carbon filtration, chemical disinfection, reverse osmosis, forward osmosis, and ultraviolet light disinfection. Filtration pressure is supplied by a hand or foot pump, and two rechargeable batteries are required for the UV sterilization unit. The advantages and limitations of each technique are investigated, with learning performance criteria measured by knowledge of: material costs, contaminant removal or neutralization capabilities (from large sediment to bacteria and viruses to chemicals), robustness and longevity, and power requirements and efficiencies. Finally, suitable combinations of treatment techniques are studied for specific contamination issues, with the ultimate goal of producing potable water. The importance of sustainable water use is also discussed. Background information and suggested experiments are introduced through accompanying educational packets. This system has had a successful impact on undergraduate education. The metrics of success include a published journal article, an awarded EPA P3 educational grant and a pending patent for the undergraduates involved in the development of the Lab. Other undergraduates are currently involved in a design for manufacturability study. Finally, the Lab has served as a demonstration tool in a new interdisciplinary engineering course “Integrated Approaches to Sustainable Development.” The Adaptive WaTER Lab has also been used in hands-on outreach to over 300 underrepresented K-12 students in the Houston area. Two high school students borrowed the original prototype of the Lab to use in an Earth Day demonstration, and one student recently worked on an individual project using the Lab. Because the Lab is portable and requires only human and solar power (to recharge the batteries via a solar backpack), it is also ideal for educational efforts in developing nations. Labs are currently being produced for outreach and donation via three international projects to install water purification systems and/or educational Labs in schools and clinics in Mexico, Lesotho and Swaziland, in collaboration with the Beyond Traditional Borders and Rice 360 health initiatives.

Full textAbstract:
In the automotive industry, the need to meet the durability requirements in a very early stage of the development of a new vehicle model is becoming more and more crucial. This is a key factor that can reduce the time to market and avoids modifying substantially the design if a component fails earlier than expected. This is also a challenging task for several reasons; in the early phase the primary design suffers from a lack of knowledge about the loads that the new vehicle will experience in its life. In literature ([1][2][5][6][7]) several methods have been proposed; for instance the so-called digital test track approach ([1]) is a CAE-based tool in which the vehicle and the road are modeled in a multibody environment together with a detailed representation of the tire and the driver in order to perform a replication of a test drive. This predictive method is very valuable but still requires a lot of information about the vehicle’s components that is usually not available at this stage of the vehicle development. On the other hand a pure test-based procedure suffers from other problems such as the need of a mule vehicle and long and costly test campaigns that need to be repeated at each component’s modification. A hybrid approach has then been proposed and implemented successfully by LMS on industrial size cases. This approach known as Time Waveform Replication (TWR) ([2]) relies on a set of test data and multibody model available from test drives carried out on a predecessor or a vehicle similar to the one that is being currently designed. The data collected on a road test is used to back-calculate the equivalent spindle displacements that will cause the same forces on the multibody model that are experienced in the test sessions. This approach has several beneficial aspects with respect to the two mentioned before. The tire model does not need to be accurate since the displacement are applied directly to the spindles (but the application can be easily extended to “road profile identification” if a detailed tire model is available). Moreover it is well known that if the forces measured at the spindles are applied directly to the unconstrained multibody model, it will result in an undesired drift of the model due to a mismatch in the mass and inertial properties between the real vehicle and its model. This is even more important when measured forces are applied to a new vehicle model that is only similar to the tested one. The TWR approach relies on a linearized model of the vehicle that is derived directly from its multibody representation. Then the spindle displacements are back-calculated by pseudo-inversion of the Frequency Response Function of the system and the application of the desired target signals. This method gives a direct result only if the system is linear; this is typically not the case in the field of vehicle dynamics where the geometry of the suspension, the non-linear properties of the dampers and bushings together with the intrinsic non-linear nature of the constrained equation of motion implies that the linearized model used by TWR is valid only for small changes to the configuration at the instant of linearization. To cope with this problem, the TWR sets up an iterative process that uses the output error to update the input. In case of high non-linearities or large changes in the configuration the linearized model can be also updated. In this paper the integration of the TWR process in a multibody code such as LMS Virtual.Lab Motion is described. In particular a new tool named LMS Motion-TWR has been developed. The application guides the engineer in setting up the models inputs and outputs, allows to drive the multibody code to compute the linearized model and the association between the test data and the numerical responses of the model. The computation of the driving signals is performed by TWR core solver as a background process allowing the user to focus on the analysis of the results rather than spending time in dealing with file conversion and transfer from one software to another as was done in the past. Moreover several post-processing tools are available such as time and frequency domain plots, RMS error and X-Y plots. Finally this paper describes the application of the tool in an industrial case scenario using a model of a quad. A quad was equipped with several sensors and driven on a test track. The collected data is then used in the Motion TWR software to compute the equivalent spindle displacements. Since some of the front suspension parts are modeled as flexible bodies the reverse load identification analysis is completed by a durability calculation.

The sizing of surge protection devices for both compressor and surrounding system may require the knowledge of performance curves in 2nd quadrant with a certain level of accuracy. In particular two performance curves are usually important: the pressure ratio trend versus flow rate inside the compressor and the work coefficient or power absorption law. The first curve allows estimating mass flow in the compressor given a certain pressure level imposed by system, while the second is important to estimate the time required to system blow down during ESD (emergency shutdown). Experimental data are routinely not available in the early phase of anti-surge protection devices and prediction methods are needed to provide performance curves in 2nd quadrant starting from the geometry of both compressor and system. In this paper two different approaches are presented to estimate performance curves in 2nd quadrant: the first is a simple 1D approach based on velocity triangle and the second is a full unsteady CFD computation. The two different approaches are applied to the experimental data more deeply investigated in part I by Belardini E.[3]. The measurement of compressor behavior in 2nd quadrant was possible thanks to a dedicated test arrangement in which a booster compressor is used forcing stable reverse flow. The 1D method showed good agreement with experiments at design speed. In off-design condition a correlation for deviation angle was tuned on experimental data to maintain an acceptable level of accuracy. With very low reverse flow rates some discrepancies are still present but this region plays a secondary role during the dynamic simulations of ESD or surge events. The unsteady CFD computation allowed a deeper insight into the fluid structures, especially close to very low flow rates when the deviation of the 1D method and the experimental data is higher. An important power absorption mechanism was identified in the pre-rotation effect of impeller as also the higher impact of secondary flows. These two methods are complementary in terms of level of complexity and accuracy and to a certain extent both necessary. 1D methods are fast to be executed and more easily calibrated to match the available experiments, but they have limited capability to help understanding the underlying physics. CFD is a more powerful tool for understanding fluid structures and energy transfer mechanisms but requires computational times not always suitable for a production environment. 1D method can be used for standard compressor and applications for which consolidated experience have been already gathered while CFD is more suitable during the development of new products or up to front projects in general.

Abstract With the recent developments in miniaturization techniques of electronic chips, the power density of these chips has risen drastically. Available thermal management technologies like air cooled heat sink and liquid cooled heat sink are unable to keep up with the demand. However, thermal management technologies using flow boiling in microchannel heat sink can dissipate higher heat fluxes. Flow boiling technologies in micro channel heat sinks are not commercially established due to issues such as reliability, flow reversal, dry out, critical heat flux, limited knowledge of bubble dynamics, correlations, etc. In this study, performance of flow boiling in a diverging microchannel with uniform heat flux condition has been investigated. Simulations have been performed on ANSYS Fluent using Volume of Fluid (VOF). VOF is used to track the interface between different phases. The impact of angle on the bubble dynamics of the coolant and flow patterns has been studied. The simulated numerical results are compiled and presented. The results provide a clear understanding of the impact of angle on the bubble dynamics in flow boiling microchannel heat sink.

Full textAbstract:
Aim/Purpose: This paper focuses on student newspapers in the midst of digital transfor-mation and the impact this has on their future survival. Background: The ramification of digital transformation on commercial newspapers is not new, but looking at it from a big picture helped to us to connect to what has been happening with student newspapers across the United States. Methodology: Through a limited review of selected student newspapers across the country, this paper attempted to identify key challenges, trends, and best practices to determine the current as well as future state of this media model. Contribution: The knowledge gained was then used to inform a transition of a specific stu-dent newspaper to cope with its own challenges and to share this condition with other schools around the nation. Findings: Due to the digital transformation, the traditional student newspapers have been disrupted and are going through the transition into digital platforms similar to those in the commercial newspapers. Yet, the value of the content is still important. Recommendations for Practitioners: Rapidly advanced technology transform student newspapers into a real-time, highly customized, personal, rich with multimedia format. This means the newspapers must be able to reach where their readers are and deliver what their readers ask for. Recommendation for Researchers: The transition of newspapers to be more digitized calls for more studies on the rise of new generation of readership, the relentless changes in technology, the search for a sustainable revenue model for e-newspaper, as well as issues in self-generated journalism. Impact on Society: As more people gain access to portable digital devices, the desire for hard copy newspapers that report yesterday’s news is rapidly decreasing. In today’s world, the news is instantaneous and the lag time between the event and it being reported is sometimes mere seconds. Future Research: Research on “fake news” is important as newspapers become more digitalized.
