The purpose of this paper is to estimate that the start-up current parameters are stochastic or not. Electronic equipment in luminaries significantly improves their luminous efficiency, thereby increasing the energy efficiency of lighting installations. However, the use of electronics [e.g. electronic ballasts for discharge lamps or power supply units for light-emitting diode (LED) luminaries] may also cause some negative effects in lighting installations. One of such effects is large inrush current, which can greatly exceed the admissible line load and trigger the overcurrent protective devices.

The paper presents results of laboratory tests together with their statistical analysis of the inrush currents of lighting luminaires. Three road luminaires build in different technologies of similar power have been selected for the study. The theoretical distributions described by the analytical formulas matched the empirical distributions by using the MATLAB’ Statistical Toolbox.

As parameters that characterize short-time overcurrent at start-up are the maximum value of overcurrent amplitude in start-up moment (I_PIC), the duration of overcurrent in start-up moment (t_PIC) and melting integral MI. The aim of this statistical analysis of the selected parameter is to provide an overcurrent mathematical description allowing to estimate the probability of occurrence of values. For lighting luminaire fitted with magnetic ballasts, the parameters analyzed will randomly vary with the moment of power on. For electronic ballasts, the occurrence of this phenomenon depends on the adopted construction solution.

This will allow, for example, to estimate the probability of activation of protection device by comparing the value of the inrush current Joule’s integral MI with its value for the analyzed protection device. The proposed method may be useful for checking the selectivity of the protection devices in the lighting system.

The study enables application of a probabilistic model for analysis of inrush currents of lighting luminaire and predicting the possible consequences of their occurrence.

Closes by pointing out the amalgam of topics.

While the influence of individual beliefs on decision-making has been widely acknowledged, the interaction of different types of beliefs remains an under-researched topic. This study analyses how the simultaneous influence of religious beliefs and nonreligious beliefs shapes individual decision-making. This study aims to contribute to inform organizational decisions on topics potentially associated with these two types of beliefs, including corporate social responsibility matters. This study also aims to provide insights to ethical decision-making in situations of absence of social consensus, a subject that is relevant for individuals, organizations and policymakers.

This study uses fuzzy set qualitative comparative analysis to identify how different configurational groupings of Christian beliefs and humanistic beliefs lead to the acceptance or nonacceptance of euthanasia in a sample of individuals who identify as Catholic.

Among individuals sharing a Catholic religious affiliation, the authors identify three different configurations of beliefs – Cultural Catholics (religious beliefs are absent and humanistic beliefs are present), Observant Catholics (religious beliefs are present and humanistic beliefs are irrelevant) and Secular Catholics (both religious beliefs and humanistic beliefs are present).

Previous research has put forward the role of religion-related variables, such as religious affiliation and level of religiosity, for views on euthanasia. This study provides a more detailed analysis of the role of belief systems, identifying how different configurational groupings of beliefs lead to a decision grounded in moral and ethical considerations but for which there is an absence of social consensus.

Looks at the coupling of fields in a device or a system as a prescribed effect. Points out that there are 12 contributions included ‐ covering magnetic levitation or induction heating, superconducting devices and possible effects to the human body due to electric impressed fields.

This paper aims to propose a knowledge transfer partnership (KTP) model, using higher education (HE) students researching in the UK. It is focused on community engagement via charitable trusts, New Opportunities Wirksworth (NOW) & Ecclesbourne Valley Rail (EVR). The researchers designed and implemented a pilot study that explored the potential of a small, yet attractive and active, market town to diversify and regenerate using tourism. This project, which has been funded by the UK Higher Education Innovation Fund (HEIF), has been devised to operate and monitor a KTP in the culturally important heritage market town of Wirksworth, in Derbyshire.

A systems-thinking constructivist approach is used and employs problem-based learning (PBL) through engagement of students in research and data collection. The authors identified that skills for sustainable development within the community are dependent on the reintegration of complex, inter-dependent and inter-disciplinary factors. A holistic approach to the learning and knowledge shared within the community underpins UK initiatives to promote capacity development in ways to change knowledge applications across product and service boundaries. Therefore, in addition to encouraging diversification and regeneration through tourism, this project supported the University of Derby's academic agenda to promote experiential and entrepreneurial learning in students working at both undergraduate and postgraduate levels. This paper accords with the current university initiatives to meet the student employability agenda through the application of PBL and knowledge management.

The creation of outcomes and recommendations for Wirksworth's stakeholders provides sustainability through the knowledge creation and sharing processes. There are seven outcomes that chart a path to development and knowledge transfer (KT) and sharing. The authors simultaneously provided an environment for students to gain skills and a community to acquire new knowledge, and these are the outcomes and output of this project. New learning styles may support inclusive academic practice (see related samples of PBL such as Ineson and Beresford in HLST resources 2001). Implications for building a KT community through the social capital accumulated in the project are explored.

In taking PBL from the classroom to the community, the authors have created a new KT environment in which skills can be acquired and a regeneration strategy can be tested in a work-or-practice-related setting. Students recognise that they are building learning for themselves that is unique in that it cannot be recreated in a classroom setting. The authors see this project developing into a robust long-term partnership between communities and institutions with KT benefits to teaching staff in addition to students. These benefits will include new skills for PBL, working collaboratively with partners in the community to develop key skills in HE students, innovation in assessment, inclusive learning and teaching, experiential and entrepreneurial learning in practice.

There are a number of conflicts today involving groups and individuals as regards nature in its various forms. The aim of this article is to examine how these give rise to changes in the forms of critique and justification that underpin them. Based on various points of disagreement as to how nature should be developed, three possibilities of change have been put forward for examination according to the importance of the transformations required: (a) integration of the model into existing orders of justification, (b) development of a new order based on the same model, (c) serious adjustment of the underlying common matrix of orders and the basis it offers for appreciating injustice.

With the rapid improvement in digital infrastructure, the popularity of digital devices and smartphones in every pocket, the yearning to stay connected with others has increased manifold, especially in youngsters. This has raised multiple concerns primarily related to the problematic usage of the internet (PUI). The current research study aims to scrutinize the association between PUI, psychological and mental health (PMH), social media fatigue (SMF), fear of missing out (FOMO), desire to disconnect (DD) and its relation with a novel phenomenon of joy of missing out (JOMO).

The present research study embraces the empirical research method through quantitative analysis. The proposed theoretical model was empirically tested using primary data, collected through a self-designed structured questionnaire. The study sample included individuals between 16 and 39 years of age as these are the most active demographics on social media. The model is empirically tested with the help of structural equation modeling applied using software IBM AMOS 20.0 and SPSS 22.0. Initially, first-order confirmatory factor analysis was conducted, to measure and test the fit indices of the proposed model. Secondly, path analysis using structural equation modeling was carried out for the model.

Empirical synthesis of this research shows that PUI significantly and positively impacts mental and psychological health, FOMO and SMF. Also, SMF significantly and positively affects the DD which significantly and positively affects the JOMO. However, as depicted by the results of this study, FOMO have no considerable impact on SMF.

A study that connects the PUI with PMH, SMF and FOMO is rare to find. Second, this study uses data collected from social media users of India in the age group of 16–39 years. This slice of the population is most active in internet, and internet-enabled platform and are scantly studied, especially in the Indian context. This makes the study more exciting and crucial.

The purpose of this paper is to explore query expansion via conceptual distance in thesaurus indexed collections

An extract of the National Museum of Science and Industry's collections database, indexed with the Getty Art and Architecture Thesaurus (AAT), was the dataset for the research. The system architecture and algorithms for semantic closeness and the matching function are outlined. Standalone and web interfaces are described and formative qualitative user studies are discussed. One user session is discussed in detail, together with a scenario based on a related public inquiry. Findings are set in context of the literature on thesaurus‐based query expansion. This paper discusses the potential of query expansion techniques using the semantic relationships in a faceted thesaurus.

Thesaurus‐assisted retrieval systems have potential for multi‐concept descriptors, permitting very precise queries and indexing. However, indexer and searcher may differ in terminology judgments and there may not be any exactly matching results. The integration of semantic closeness in the matching function permits ranked results for multi‐concept queries in thesaurus‐indexed applications. An in‐memory representation of the thesaurus semantic network allows a combination of automatic and interactive control of expansion and control of expansion on individual query terms.

The application of semantic expansion to browsing may be useful in interface options where thesaurus structure is hidden.

This paper aims to focus on flow boiling heat transfer in an asymmetrically heated minichannel. Two-dimensional inverse heat transfer problem was solved using the Trefftz and Beck methods. The primary purpose was to find an enhanced surface that could help intensify heat transfer.

The experimental set-up and methodology for FC-72 boiling heat transfer in two parallel vertical rectangular minichannels with smooth or enhanced heated surfaces was presented. The heat transfer coefficient was calculated using the Trefftz and Beck methods.

The results confirm that considerable heat transfer enhancement takes place when selected enhanced heated surface is used in the minichannel flow boiling and that it depends on the type of surface enhancement. The analysis of the experimental data revealed that the values and distributions of the heat transfer coefficient obtained using the Beck and Trefftz methods were similar.

Many studies have been recently devoted to flow boiling heat transfer in minichannels because of the rapid development of high-performance integrated systems generating large amounts of heat. Highly efficient small-size cooling systems for new-generation compact devices are thus in great demand.

The present results are original and new in the study of cooling liquid boiling in minichannels with enhanced heated surfaces that contribute to heat transfer enhancement. The paper allows the verification of state-of-the-art methods of solving the inverse problem by using empirical data from the experiment. The application of the Trefftz and Beck methods for finding a solution of the inverse heat transfer problem is promising.

The purpose of this paper is to develop and validate an extended Define-Measure-Analyze-Improve-Control (DMAIC) based framework through a case study of an Indian fasteners manufacturing organization.

Research methodology is established on the development of the existing DMAIC framework through an extensive literature review of 25 LSS/DMAIC based frameworks and discussions held with practitioners. This paper also depicts a case study of Indian manufacturing organization for validation of the developed framework.

The study proposed an extended DMAIC based framework for effective implementation of Lean Six Sigma (LSS) methodology. Furthermore, this framework has been implemented successfully in the Indian manufacturing organization and showed encouraging results. The in-house rejections of Nut Cylinder Head (NCH) were brought down to 966 from 2910 PPM and sigma level was improved by 0.40. The case organization has achieved significant improvements in the process capability, customer satisfaction, and cost savings of US$ 0.25 million in one financial year. Intangible benefits like improvements in employee's morale, communication, housekeeping and decision-making capabilities were also observed significantly.

The proposed DMAIC based framework has been implemented successfully in the Indian case organization, and the results will enable the policymakers, specifically practitioners, to strategically leverage the resources for successful implementation of the LSS in healthcare, aerospace, service sectors etc.

This research develops a DMAIC based framework which can be used to implement LSS effectively in different industries. Moreover, the pre (initial/introduction) and post (validation/verification) implementation phase provides the top management, an edge to think strategically into broader improvement areas.
