The purpose of this study is to form fabrication and electrical characteristics of passive device embedded substrate that is embedded chip bead inductor and chip capacitor inside substrate for the application of radio frequency (RF) modules.

Passive device embedded substrate was fabricated using embedding process that consists of lamination process, laser drilling at the electrode Cu pads of passive components, electro-less Cu plating formation process such as photolithography, electrolytic Cu plating and etching. Impedance and capacitance characteristics of the fabricated passive device embedded substrate were evaluated.

By checking what embedded components are placed in the appropriate place using failure analysis via connection performance between copper plane and embedded components was verified. For measuring electrical characteristics of the fabricated passive device embedded substrate, the evaluation was done using test methods like continuity test for checking interconnections which are not connected to any embedded components and in-circuit test for checking interconnections which are connected to any embedded component. From in-circuit testing for embedding passive components with series and parallel circuits, the authors verified how to test passive device embedded substrate by using capacitance and impedance measurement with the comparison of measured results between good samples and bad samples.

Ultra miniaturized and low-profile mobile products are driving the need for embedded passive component integration technologies using a novel manufacturing-compatible organic substrate and interconnect technologies. Fabrication and test methods for passive device embedded substrate described in this paper are expected to lead to be developed to make quality measurable for the application of RF modules.

This paper aims to share the current state of embedded librarianship in learning management systems as reported by academic librarians. The paper highlights the best practices, as well as continuing questions, in the field of embedded librarianship.

The authors collected participant feedback in two active, participatory panel discussions at national conferences. The open forums were centered on three guiding themes of embedded librarianship: building connections with faculty and students; utilizing technology tools; and providing information literacy and assessment. Participants answered directed questions, and their responses were recorded and analyzed for this paper.

Librarians report an increasing demand for library services in learning management systems. Collaboration and partnerships across campus are required for successful embedded librarian projects. Technology tools continue to evolve and change, and most librarians can anticipate using multiple learning management systems over time. There is an ongoing need for professional development in online library instruction and assessment.

This paper provides a snapshot of the current state of embedded librarianship in learning management systems. It offers insights about what academic librarians value, what they have learned and what concerns they still have about library instruction in online environments.

With the advent of new materials and technologies that enable passive components to be embedded within electronic substrates, one key question that arises is: under what circumstances (and for what type of applications) is it economically viable to consider using embedded passives? The economic issues that must be considered consist of a combination of manufacturing costs and throughputs, and non‐manufacturing life cycle costs. This paper discusses the assessment of manufacturing costs associated with embedding resistors and capacitors in printed circuit boards and provides cost modeling results for an avionics board. The discussion is extended to include optimizing the specific embedded passive content in a board and design for production modeling when embedded passives are present. Life cycle cost issues are also qualitatively discussed.

Embedded passives technologies can provide benefits of size, performance, cost, and reliability to high density, high‐speed designs. A number of embedded passive technology solutions are available to the designer. Based on our experience with Rohm and Haas's thin‐film, high‐ohmic, InSite^TM embedded resistor materials (500 and 1000 Ω/sq), this paper provides some guidelines for selecting the appropriate embedded resistor technology and implementing it at a board fabricator. The design of embedded resistors, and the trade‐offs between resistor size, tolerance, and capability of board fabrication processes, are analyzed in detail. This paper also discusses selection of the appropriate embedded capacitor technology and introduces some initial results on Rohm and Haas's thin‐film, high‐D_k, InSite embedded capacitor material (200 nF/cm²).

The present study discusses the future of academic librarianship, emphasizing the essential aspects of embedded librarianship practice and implementation. In addition, it also explores the changing role of academic librarians, addressing challenges and opportunities in various contexts and highlighting the significance of embedded librarianship practice.

The study employs a literature review to understand the significance of embedded librarianship and its implementation in academic libraries. The researchers searched a range of electronic data sources, including Emerald Insight, Taylor and Francis, Science Direct, Web of Science, EBSCOhost, Scopus, Information Science and Technology Abstracts (LISTA), Library and Information Science Abstracts (LISA), etc. Moreover, only peer-reviewed articles were considered for the review.

The study identified five major competencies, i.e. communication and interpersonal skills, teaching, research, collaboration and coordination and technological expertise, that are essential for implementing embedded librarianship in the academic library. However, in developing countries, there are various challenges faced by academic librarians such as inadequate ICT infrastructure, resource accessibility, cooperations, cultural diversity and a lack of financial support from the authority were major barriers to the successful implementation of embedded librarianship.

The study findings are of considerable value to academic librarians, providing them with the opportunity to assess and evaluate their competencies and acquire the essential skills for implementing embedded librarianship. Further, the study also recommended some practical implications of embedded librarianship practices in the academic environment.

The findings and insights from this investigation provide a valuable perspective on the future of academic librarianship, shedding light on the critical role that embedded librarianship plays in shaping its direction.

Physics-informed neural networks (PINNs) have become a new tendency in flow simulation, because of their self-advantage of integrating both physical and monitored information of fields in solving the Navier–Stokes equation and its variants. In view of the strengths of PINN, this study aims to investigate the impact of spatially embedded data distribution on the flow field results around the train in the crosswind environment reconstructed by PINN.

PINN can integrate data residuals with physical residuals into the loss function to train its parameters, allowing it to approximate the solution of the governing equations. In addition, with the aid of labelled training data, PINN can also incorporate the real site information of the flow field in model training. In light of this, the PINN model is adopted to reconstruct a two-dimensional time-averaged flow field around a train under crosswinds in the spatial domain with the aid of sparse flow field data, and the prediction results are compared with the reference results obtained from numerical modelling.

The prediction results from PINN results demonstrated a low discrepancy with those obtained from numerical simulations. The results of this study indicate that a threshold of the spatial embedded data density exists, in both the near wall and far wall areas on the train’s leeward side, as well as the near train surface area. In other words, a negative effect on the PINN reconstruction accuracy will emerge if the spatial embedded data density exceeds or slips below the threshold. Also, the optimum arrangement of the spatial embedded data in reconstructing the flow field of the train in crosswinds is obtained in this work.

In this work, a strategy of reconstructing the time-averaged flow field of the train under crosswind conditions is proposed based on the physics-informed data-driven method, which enhances the scope of neural network applications. In addition, for the flow field reconstruction, the effect of spatial embedded data arrangement in PINN is compared to improve its accuracy.

Extended research efforts have been dedicated to understanding how different aspects of online surveys impact the response rate and quality of collected data. With the hope to yield higher response rates, leading survey software solutions (e.g., SurveyMonkey, Qualtrics, QuestionPro) introduced a new technique of embedding a question from an online survey into invitation emails sent to the respondents. The purpose of this chapter is to examine the impact of embedded questions on survey response rate and quality. The results of two experimental studies show that respondents are more likely to respond to a survey with an embedded question compared to an email without one. No statistically significant differences were discovered regarding data quality that was assessed via survey completion rate, respondent bias, and attention check questions. The chapter provides suggestions and guidelines for increasing online surveys' response rate and quality.

This paper aims to focus on the characteristics of a two-tier network featuring internal subject cooperation and external embedded cooperation in the context of regional innovation systems (RISs) and explore the influence of network characteristics on knowledge emergence.

Using social network analysis, a two-tier internal and external cooperation network of a RIS is constructed. A negative binomial regression method is used to explore the effects of the characteristics of these two-tier internal and external networks on knowledge emergence, the moderating effect of the cooperation knowledge base in this context is investigated and grouping and quantile regressions are used to conduct heterogeneity analysis.

The scale of the internal cooperation network has a positive effect on knowledge emergence, and the betweenness centralization of the internal cooperation network has an inverted U-shaped effect on knowledge emergence. The scale and structural holes of the external embedded network have an inverted U-shaped effect on knowledge emergence. Furthermore, the internal cooperation knowledge base weakens the influence of the external embedded network on knowledge emergence.

This research may enlighten policymakers with respect to improving the scale and structure of the RIS cooperation network and matching the embedded network based on the internal cooperation knowledge base to promote knowledge emergence.

This research contributes to the study of knowledge emergence by exploring the influence of a two-tier network structure and scale characteristics on knowledge emergence in RISs. This paper also extends the framework of relevant research by integrating the internal cooperation knowledge base into the analysis of externally embedded cooperation and knowledge emergence.

This study aims to examine the state of embedded librarianship in African academic libraries by exploring the extent of librarian embedment in research processes in selected academic libraries in Africa.

A survey was conducted to collect data using an online questionnaire. The study population was comprised of librarians who directly support researchers throughout the research process in the scholarly communication and information services sections. Purposive sampling was used to select librarians, and 63 responses were received from the target of 100. The collected data were analysed using the statistical package for the social sciences (SPSS) software, and content analysis was used to analyse open-ended questions.

The study results showed that the extent and nature of librarians' embeddedness in the research process vary across different university contexts in Africa. Challenges and areas of research skill gaps among librarians were identified, and propositions to address the research skill gaps were provided.

The study findings can be used as a framework for libraries to embed librarians in the research process. The study made recommendations with practical implications for library practitioners in academia, and institutions offering library and information science education, and the library management responsible for the research process.

A study brings a novel perspective by examining the state of embedded librarianship in the African context. Its contribution generates knowledge and insights that inform the development of effective embedded librarianship practices in African academic libraries to enhance research support services and advancement of scholarly research in the region.

The main purpose of this study was to examine the effectiveness of embedded social media channels and determine whether the embedded social media channels enhance the overall experience of travelers using the hotel Web sites.

A true-experimental, between-group and post-test-only design was used to address the primary research questions. Two privately accessible complete versions of the Web site (one with embedded social media channels and one without them) were designed for the experiment. The uses and gratifications approach was used to test the proposed hypotheses. Data were analyzed using ANOVA.

The results of this study revealed that embedded social media channels on the hotel Web site enhanced travelers’ social gratifications of perceived social interaction. Apart from these benefits for travelers seeking social gratifications, embedded social media channels did not enhance the overall experience (content and process gratifications) of travelers using the Web site.

In the case of embedded social media on hotel Web sites, this study suggests that hotel managers measure return on engagement to examine the effectiveness of embedded social media, instead of return on investment.

The study revealed that the emergence of embedded social media channels and their integration on hotel Web sites will have significant influence on travelers who seek social gratifications.

The findings of this study offer new empirical evidence that embedded social media channels enhance only travelers’ perceived social interaction during their first visit to the hotel Web site.
