Capacitors are one of the most common passive components on a circuit board. From a tiny toy to substantial satellite, a capacitor plays an important role. Untimely failure of a capacitor can destruct the entire system. This research paper targets the reliability assessment of tantalum capacitor, to reduce e-waste and enhance its reusable capability.

The residual lifetime of a tantalum capacitor is estimated using the empirical method, i.e. military handbook MILHDBK2017F, and validated using an experimental approach, i.e. accelerated life testing (ALT). The various influencing acceleration factors are explored, and experiments are designed using Taguchi's approach. Empirical methods such as the military handbook is used for assessing the reliability of a tantalum capacitor, for ground and mobile applications.

After exploring the lifetime of a tantalum capacitor using empirical and experimental techniques, an error analysis is conducted, which shows the validity of empirical technique, with an accuracy of 95.21%.

The condition monitoring and health prognostics of tantalum capacitors, for ground and mobile applications, are explored using empirical and experimental techniques, which warns the user about its residual lifetime so that the faulty component can be replaced in time.

The purpose of this study is to select the most accurate and the most efficient method in estimating Weibull parameters at Agadir region in Morocco.

In this paper, Weibull distribution is used to model the wind speed in hourly time series format. Since several methods are used to adjust the Weibull distribution to the measured data, in reporting and analyzing the easiest and the most effective method, seven methods have been investigated, namely, the graphical method (GM), the maximum likelihood method (MLM), the empirical method of Justus (EMJ), the empirical method of Lysen (EML), the energy pattern factor method (EPFM), Mabchour’s method (MMab) and the method of moments (MM).

According to the statistical analysis tools (the coefficient of determination, root mean square error and chi-square test), it was found that for five months, the MLM presents more efficiency, and for four months, EMJ is ranked first and it is ranked second for February. To select only one method, the selected methods (MLM and EMJ) were compared by calculating the error in estimating the power density using Weibull distribution adjusted by those methods. The average error was found to be −0.51 and −4.56 per cent for MLM and EMJ, respectively.

This investigation is the first of its kind for the studied region. To estimate the available wind power at Agadir in Morocco, investors can directly use MLM to determine the Weibull parameters at this site.

The purpose of this study is to conduct a meta-analysis of prior scientometric research of the knowledge management (KM) field.

A total of 108 scientometric studies of the KM discipline were subjected to meta-analysis techniques.

The overall volume of scientometric KM works has been growing, reaching up to ten publications per year by 2012, but their key findings are somewhat inconsistent. Most scientometric KM research is published in non-KM-centric journals. The KM discipline has deep historical roots. It suffers from a high degree of over-differentiation and is represented by dissimilar research streams. The top six most productive countries for KM research are the USA, the UK, Canada, Germany, Australia, and Spain. KM exhibits attributes of a healthy academic domain with no apparent anomalies and is progressing towards academic maturity.

Scientometric KM researchers should use advanced empirical methods, become aware of prior scientometric research, rely on multiple databases, develop a KM keyword classification scheme, publish their research in KM-centric outlets, focus on rigorous research of the forums for KM publications, improve their cooperation, conduct a comprehensive study of individual and institutional productivity, and investigate interdisciplinary collaboration. KM-centric journals should encourage authors to employ under-represented empirical methods and conduct meta-analysis studies and should discourage conceptual publications, especially the development of new frameworks. To improve the impact of KM research on the state of practice, knowledge dissemination channels should be developed.

This is the first documented attempt to conduct a meta-analysis of scientometric research of the KM discipline.

This research is very important to conduct to review government policy on Indonesian contract law that still uses contract law inherited from Dutch product (BW) and review which regulations are to be adapted to current development of contract law. This research’s novelty is that new rules will be found in Indonesian contract law.

This research used normative and empirical methods. Normative research is dogmatic research or one that analyzes legislation using secondary data consisting of primary, secondary and tertiary legal materials. Besides the normative method, the research was also conducted using empirical method through direct interview and observation in some government agencies, such as the Directorate General of Legislation, Ministry of Law and Human Rights (HAM) and Chairman of Legal Product Formation Division, House of People’s Representatives of the Republic of Indonesia and the Civil Law Teaching Association (APHK).

This research found that new Indonesian contract law is very important to give legal certainty and justice to the people, and the contract law must regulate important matters related to the sources of contract besides agreement and law, related to termination, unjust enrichment, negotiation, good faith, public contract and private contract and related to legal act and validity of electronic contract.

The novelty of this research is that new rules will be found in Indonesian contract law. This research is different from previous researches conducted by Sigit Irianto (2013) and Deviana Yuanitasari (2020), that discuss only on contract law development related only to the good faith principle.

Drafting contract law is a relatively heavy duty due to the factor of law pluralism that contains contract aspect in Indonesia such as customary law aspect, Islamic law aspect, regional aspect, international aspect and other aspects. In fact, meanwhile, there is rapid development in the community with regard to business transactions that are also followed with contract law development. Therefore, amendment is needed for the Indonesian contract law to adapt to the people’s need for law, and this change agenda is also addressed to updating the contract law.

Civil law reform, especially contract law, is deemed very important for Indonesia, because based on field fact, people do their business contract by applying contract law that is not yet regulated in the contract law in KUHPerdata; thus, new contract law is needed that regulates important matters related to sources other than agreement and law.

It is very important to conduct this research to review government policy in Indonesian contract law that still uses the contract law inherited from Dutch product (BW) and review what regulations should have been adjusted to current development of contract law. The novelty of this research is that new rules will be found in Indonesian contract law. This research is different from previous researches conducted by Sigit Irianto (2013) and Deviana Yuanitasari (2020), that discuss only on contract law development related only to the good faith principle.

This paper stimulates methodological debates and advances the research agenda for qualitative research about time and temporality in organizing processes. It develops a framework for studying the temporal in organizing that contributes by: (1) providing an overview to prepare for and navigate various methodological challenges in this regard, (2) offering inspiration for relevant solutions to those challenges and (3) posing timely questions to facilitate temporal reflexivity in scholarly work.

Based on a literature review of studies about temporality in organizing processes, the authors develop a framework of well-acknowledged methodological challenges, dilemmas and paradoxes, and pose timely questions with which to develop potential solutions for research about organization and time.

The framework of this study offers a synthesis of methodological challenges and potential solutions acknowledged in the organization studies literature. It consists of three interrelated dimensions of methodological challenges to studying temporality in organizing processes, namely: empirical, analytical and representational challenges. These manifests in six subcategories: empirical cases, empirical methods, analytical concepts, analytical processes and coding, representing researchers’ temporal embeddedness and representing multiple temporalities.

This paper allows scholars to undertake a more ambitious, collective methodological discussion and sets an agenda for studying the temporal in organizing. The framework developed stimulates researchers’ temporal reflexivity and inspires them to develop solutions to specific methodological challenges that may emerge in their study of the temporal in organizing.

This work aims to deal with a comprehensive review of design methods for aircraft directional stability and vertical tail sizing. The focus on aircraft directional stability is due to the significant discrepancies that classical semi-empirical methods, as USAF DATCOM and ESDU, provide for some configurations because they are based on NACA wind tunnel (WT) tests about models not representative of an actual transport airplane.

The authors performed viscous numerical simulations to calculate the aerodynamic interference among aircraft parts on hundreds configurations of a generic regional turboprop aircraft, providing useful results that have been collected in a new vertical tail preliminary design method, named VeDSC.

The reviewed methods have been applied on a regional turboprop aircraft. The VeDSC method shows the closest agreement with numerical results. A WT test campaign involving more than 180 configurations has validated the numerical approach.

The investigation has covered both the linear and the non-linear range of the aerodynamic coefficients, including the mutual aerodynamic interference between the fuselage and the vertical stabilizer. Also, a preliminary investigation about rudder effectiveness, related to aircraft directional control, is presented.

In the final part of the paper, critical issues in vertical tail design are reviewed, highlighting the significance of a good estimation of aircraft directional stability and control derivatives.

Recent work has demonstrated that stochastic models, incorporating a time parameter, have great potential value for library management in predicting future use of library materials, particularly in the presence of ageing of materials. In this paper a simple empirical Bayes method is presented which avoids the analytic complexity of earlier models and which may therefore be more attractive to the library manager. In particular, the ‘prediction profile’ is advocated as a useful additon to the manager's toolbox.

The purpose of this paper is to explore knowledge-intensive business services (KIBS), to understand how they implement their service development (SD) processes and how these processes are related to their knowledge bases (KB) as not enough studies have focussed on the understanding of KIBS heterogeneity, by analysing the nature and essence of these firms’ activities.

The work adopts the case study approach involving 12 KIBS firms with different KB according to Bjorn Asheim and colleagues’ “synthetic, analytical, symbolic model”, which identifies synthetic, analytical and symbolic primary KB.

The research results showed how the SD processes are systemised in KIBS companies depending on the KB. The proposed empirical method for defining KB confirmed the assumed existence of a new type or subtype of KB for legal companies “Compliance/Interpretive”.

Further research, based on a larger number of companies, is needed to confirm or complement the results of this research, as well as to find more methods to define and evaluate KB on an empirical basis.

The correct classification of the applied KB can help a company to create effective processes for developing innovative services, while understanding of knowledge dynamic in general – to organise a working process that corresponds to employees’ needs and is more adaptable to the changes in society.

The study proposed a new empirical method for defining and evaluating KB in KIBS companies based on their SD processes. This study makes a significant contribution to research by identifying knowledge-integration practices needed to enhance innovation performance.

This paper aims to assess the main sources, key propositions and empirical methods available to researchers taking a “subjectivist” perspective on the creation of opportunities by entrepreneurs.

Subjectivist research is defined behaviourally: it emphasises the internal, mental processes and subjective meanings incorporated in entrepreneurial acts. The alertness literature is accorded special attention; it originally possessed a strong subjectivist orientation and focused on opportunity recognition.

A subjectivist approach has distinct advantages: it requires researchers to observe, analyse and explain entrepreneurial creativity with reference to entrepreneurs' internal, personal interpretations of their environment. Subjectivist approaches ask: how do entrepreneurs create profit opportunities? Subjectivists extend the concept of entrepreneurial alertness to include analysis of knowledge construction processes.

Fruitful theoretical and applied subjectivist research de‐emphasises entrepreneurs' exploitation of existing opportunities; knowledge construction fundamental to the genesis of creative behaviour becomes central.

There are several empirically oriented organising frameworks available in the literature consistent with a subjectivist orientation to entrepreneurial creativity.

This is the first attempt to assess and synthesise modern subjectivist work on the creative dimension of entrepreneurial behaviour. It identifies complementary conceptual developments on the interface between economics and psychology. Some promising empirical methods are suggested.

While recent theoretical discussions around discourse–material relationality have facilitated important conceptual and analytical advancements within the broader field of CMS, less progress has been made methodologically with regard to innovating empirical methods and data modes. Therefore, the purpose of this article is to contribute to strengthening the methodological focus in the literature when grappling with the relationality of discourse–materiality and co-constitution. This includes a method-retooling framework inspired by new materialism.

In this article, the authors engage at the methodological level by developing a method-retooling framework that combines insights from organizational discourse studies and new materialist thinking. This framework enables a retooling of existing methods to become sensitive to multimodality and offers two concrete examples that were developed during fieldwork for a multi-sited and multi-method case study in 2018.

Based on the framework for retooling methods for multimodality, two illustrations are offered. These include retooling interviews by employing multimodal vignettes and retooling observations by using multimodal mappings. They are unfolded and discussed regarding their appropriation of discourse–material relationality.

This paper includes original research and method developments – adding a critical focus on the methodological aspects and potential advancements that are necessary in the wake of the ongoing debates around discourse–materiality across CMS and specifically within studies of organizational discourse and CCO. By suggesting a framework, the authors stimulate methodological explorations and contribute to furthering method developments that are equal to the rich conceptual progress made within the field.
