The purpose of this paper is to investigate the effect of process parameters of fused deposition modelling (FDM) 3D printing process on viscoelastic responses (creep compliance and recoverable compliance) of FDM built parts using a novel experimental design technique.

As part of the process characterization, a recently developed class of three-level design methodology – definitive screening design (DSD) – was used in this study to fit a second-order polynomial regression model. Artificial neural network (ANN) was also used to determine the optimal process parameters to improve creep compliance and recoverable compliance. The relationship between layer thickness, air gap, raster angle, build orientation, road width, number of contours and creep performance of FDM fabricated part was thereafter established empirically. Scanning electron microscope (SEM) is used to examine and characterize the morphology of the structures for some samples.

This study found that the creep resistance of FDM-manufactured part is significantly influenced by layer thickness, air gap, raster angle and number of contours and it can be improved by optimizing the settings of the selected parameters. The relationship between FDM process parameters and creep properties was determined, with the best creep performance observed by using 0.127 mm of layer thickness, zero air gap, zero raster angle, build orientation of 17.188°, road width of 0.4572 mm and 10 contours. Finally, the result is verified by confirmation experiments. The results prove that a DSD is a very effective design in characterizing the influence of process parameters on creep properties of FDM-built part at the lowest cost.

The originality of this paper lies in characterizing and optimizing the effect of process parameters on creep performance of FDM manufactured part that has not been studied in all previous studies. The paper highlights, for the first time, how the application of DSD can overcome most of the limitations encountered in the conventional techniques. This study can be used as a guide to the different additive manufacturing users of various industries and the results provide a good technical database on how FDM process parameters influence the creep performance of manufactured parts.

Fused deposition modeling (FDM) has become an increasingly important process among the available additive manufacturing technologies in various industries. Although there are many advantages of FDM process, a downside of its industrial application is the attainable dimensional accuracy with tight tolerance without compromising the mechanical performance. This paper aims to study the effects of six FDM operating parameters on two conflicting responses, namely, dynamic stiffness and dimensional stability of FDM produced PC-ABS parts. This study also aims to determine the optimal process settings using graphical optimization that satisfy the dynamic mechanical properties without compromising the dimensional accuracy.

The regression models based upon IV-optimal response surface methodology are developed to study the variation of dimensional accuracy and dynamic mechanical properties with changes in process parameter settings. Statistical analysis was conducted to establish the relationships between process variables and dimensional accuracy and dynamic stiffness. Analysis of variance is used to define the level of significance of the FDM operating parameters. Scanning electron microscope and Leica MZ6 optical microscope are used to examine and characterize the morphology of the structures for some specimens.

Experimental results highlight the individual and interaction effects of processing conditions on the dynamic stiffness and part accuracy. The results showed that layer thickness (slice height), raster-to-raster air gap and number of outlines have the largest effect on the dynamic stiffness and dimensional accuracy. The results also showed an interesting phenomenon of the effect of number of contours and the influence of other process parameters. The optimal process conditions for highest mechanical performance and part accuracy are obtained.

The effect of FDM processing parameters on the properties under dynamic and cyclic loading conditions has not been studied in the previous published work. Furthermore, simultaneous optimization of dynamic mechanical properties without compromising the dimensional accuracy has also been investigated. On the basis of experimental findings, it is possible to provide practical suggestions to set the optimal FDM process parameters in relation to dynamic mechanical performance, as well as the dimensional accuracy.

Additive manufacturing (AM) technology has a huge influence on the real world because of its ability to manufacture massively complicated geometrics. The purpose of this study is to use CiteSpace (CS) visual analysis to identify fused deposition modeling (FDM) research and development patterns to guide researchers to decide future research and provide a framework for corporations and organizations to prepare for the development in the rapid prototyping industry. Three-dimensional printing (3DP) is defined to budget minimize manufactured input and output for aviation and the medical product industrial sectors. 3DP has implemented its potential in the Coronavirus Disease of 2019 (COVID-19) reaction.

First, 396 original publications were extracted from the web of science (WOS) with the comprehensive list and did scientometrics analysis in CS software. The parameters are specified in CS including the span (from 2011 to 2019, one year slice for the co-authorship and the co-accordance analysis), visualization (show the merged networks), specific criteria for selection (top 20%), node form (author, organization, region, reference cited; cited author, journal and keywords) and pruning (pathfinder and slicing network). Finally, correlating data was studied and showed the results of the visualization study of FDM research were shown.

The framework of FDM information is beginning to take shape. About hot research topics, there are “Morphology,” “Tensile Property by making Blends,” “Use of Carbon nanotube in 3DP” and “Topology optimization.” Regarding the latest research frontiers of FDM printing, there are “Fused Filament Fabrication,” “AM,” in FDM printing. Where “Post-processing” and “environmental impact” are the research hotspots in FDM printing. These research results can provide insight into FDM printing and useful information to consider the existing studies and developments in FDM researchers’ analysis.

Despite some important obtained results through FDM-related publications’ visualization, some deficiencies remain in this research. With >99% of articles written in English, the input data for CS was all downloaded from WOS databases, resulting in a language bias of papers in other languages and neglecting other data sources. Although, there are several challenges being faced by the FDM that limit its wide variety of applications. However, the significance of the current work concerning the technical and engineering prospects is discussed herein.

First, the novelty of this work lies in describing the FDM approach in a Scientometric way. In Scientometric investigation, leading writers, organizations, keywords, hot research and emerging knowledge points were explained. Second, this research has thoroughly and comprehensively examined the useful sustainability effects, i.e. economic sustainability, energy-based sustainability, environmental sustainability, of 3DP in industrial development in qualitative and quantitative aspects by 2025 from a global viewpoint. Third, this work also described the practical significance of FDM based on 3DP since COVID-19. 3DP has stepped up as a vital technology to support improved healthcare and other general response to emergency situations.

The purpose of this study is to frame the dimensions of the external institutional environment, namely, cultural-cognitive, normative and regulative dimensions as the main actors in the organisational field. More precisely, Libyan commercial banks have been identified as empirical evidence, to identify constraints of the institutional environment governing the behaviour and decision-making of commercial banks, when adopting Islamic financial transactions.

A questionnaire has been designed for 14 Libyan commercial banks which is distributed to the Board of Directors, managers, directors of departments, and personnel. The exploratory factor analysis (EFA) and the measurement model by using the first-order and second-order confirmatory factor analysis (CFA) have been applied as essential steps to embody the conceptual framework and test the research hypotheses.

The results of the EFA indicated sufficient correlation among the dimensions of the external environment. The CFA supported this study’s hypotheses. The modelling showed that the cultural-cognitive, normative and regulative dimensions are institutional constraints impeding Libyan commercial banks’ adoption of Islamic financial transactions. Interestingly, the findings of the CFA align with the EFA findings in supporting the conceptual framework of the research. They portrayed that the cultural-cognitive dimension has been identified by explicit and implicit cognition.

This study systematically embodies the dimensions of the external institutional environment, namely, cultural-cognitive, normative and regulative dimensions, as the main factors in the organisational field to be conceptually rich lenses to investigate social considerations to reinforce institutional thought broadly. The results of this study were consistent with extant Islamic financial literature, reflecting symmetry and similarity across commercial banks, particularly at the first stage of adopting Islamic financial transactions.

This paper aims to examine the acceptance of Zakat institutions in Malaysia towards Micro Credit-Qard Hasan Financing through Zakat Fund (MCZF) for post-pandemic asnaf entrepreneurs. The study is motivated by the declining trend in Zakat collection and the increasing number of asnaf individuals in the post-pandemic period. This necessitates alternative initiatives such as the MCZF scheme by Zakat institutions. However, the reception of the MCZF scheme in Malaysia is unfavourable, despite studies suggesting its suitability for Zakat institutions and asnaf entrepreneurs.

This study adopts a qualitative methodology involving library and field research as data collection methods. The library research encompasses reviewing relevant books, articles, statutes and circulars. In terms of the field study, semi-structured interviews were conducted with five selected Zakat management officers from Zakat institutions and two proficient academics specialising in Shariah and Zakat management. The interview data generated several themes analysed using the content analysis method. Consequently, the snowball method was employed to determine the sample size of Zakat institutions, ensuring comprehensive coverage of their acceptance of the MCZF scheme.

The study’s findings reveal that three Zakat institutions accept the MCZF scheme for implementation, justifying it as a matter of differing opinions (khilaf) that allows room for ijtihad based on the current needs and well-being (maslahah). However, one of the Zakat institutions expresses unpreparedness to implement the scheme due to obstacles posed by an official fatwa. Additionally, the study demonstrates that two Zakat institutions reject the MCZF scheme, citing reasons such as the principle of direct ownership (tamlik) in giving Zakat funds, the prohibition specified by the official state fatwa, and the prevailing societal expectation of direct Zakat distribution without loans.

This study focuses solely on five Zakat institutions in Malaysia, all of which have specific fatwas concerning the MCZF scheme. Future research may explore Zakat institutions in other states. Furthermore, this study specifically concentrates on asnaf entrepreneurs. Hence, further research could investigate the applicability of the MCZF scheme for other asnaf groups, such as asnaf students.

This study examines the acceptance of Zakat institutions towards the MCZF scheme and the justifications provided by Zakat institutions for its implementation. The findings of this study can guide Zakat institutions in Malaysia in accepting and implementing the MCZF scheme. It can significantly impact these institutions by assisting asnaf entrepreneurs in securing capital and expanding their businesses.

This study has substantial implications for society, particularly for asnaf entrepreneurs, as loans provided through Zakat funds can help boost their business capital. Consequently, this can elevate the asnaf group from being recipients of Zakat to becoming contributors. Furthermore, when Zakat funds are provided as debt to asnaf entrepreneurs, they can be motivated to grow their businesses since they commit to repaying the debt through instalments.

This study analyses the acceptance of the MCZF scheme by Zakat institutions in Malaysia as an alternative initiative to support asnaf entrepreneurs after the pandemic.

The purpose of this study aims to examine the effect of fintech on pre- and post-financing credit risks faced by the Islamic banks.

This research uses primary data for fintech awareness and adoption and secondary data of various financial and economic variables from 2009 to 2021. It uses baseline regression to identify moderation of fintech controlling gross domestic products, size, return on assets and leverage. The findings are confirmed using robustness against key variable bias. It also uses a dynamic panel two-stage generalized method of moments for endogeneity.

The study finds that the fintech awareness and adoption are not the same across all Islamic countries. The Asia Pacific region is far ahead of the other two regions where Indonesia is ahead in terms of fintech awareness and adoption, and Malaysia is ahead in terms of reaping its benefits in credit risk management. Fintech affects prefinancing credit risk significantly more than postfinancing credit risk. Also, the study finds that Islamic banks suffer from the problem of “Adverse selection under Shariah compliance.”

This research invites regulators to introduce fintech in Islamic banks on war footing. Similar studies can be conducted on the role of other risks such as operational and market risks. Fintech will also help in improving the risk profile and stability of Islamic banks against systemic risks and financial crises.

This research has variety of originalities. First, it is the pioneering study that addresses the effect of fintech pre- and post-financing credit risks in Islamic banks. Second, it identifies “Adverse selection under Shariah compliance” for Islamic banks. Third, it helps identify how fintech can be useful in reducing credit risk that will help in reducing capital charge for regulatory capital.

The objective of this study aims to investigate the manner in which Human Resource Practices (HRP), leadership, and intellectual capital contribute to organisational agility within the healthcare sector, and to assess how this agility influences overall organisational performance.

This research was undertaken within healthcare organisations situated in the United Arab Emirates (UAE). The study sample comprised of 275 participants, and the distribution of the sample across various classifications closely mirrored that of the larger population. To assess the formulated hypotheses, the research utilized Partial Least Squares Structural Equation Modeling (PLS-SEM) software.

Results confirmed the proposed framework and uncovered the significance of HRP, leadership and intellectual capital on organisational agility and organisational performance in a dynamic environment like hospitals.

This study demonstrates originality by investigating hospital responsiveness within a highly dynamic context necessitating agility from both managerial and non-technical perspectives. Additionally, it explores the impact of HRP, leadership, and intellectual capital on organisational agility, along with its repercussions for overall organisational performance.

The aim of this study is to examine the perceptions of consumers on Islamic banking and finance in Pakistan. Islamic finance is an emerging phenomenon, and its survival depends on the availability, affordability and awareness. This paper attempts to fill the gap in the literature by exploring the perceptions of consumers and bankers in an attempt to gain insights so that the availability of products and awareness can be increased.

The study uses a regression model by using perception as a dependent variable and awareness, knowledge and religious motivation as independent variables. Primary data is collected using 150 questionnaires distributed amongst finance students in several universities and employees of Islamic banks in the Khyber Pakhtunkhwa (KPK) Province of Pakistan.

The findings reveal that overall consumers’ perception is positive about Islamic banking and finance in Pakistan. Statistical analysis shows that awareness, knowledge and religiosity level have a positive influence on the perception of consumers about Islamic financing products and services in Pakistan. To improve the awareness and understanding, Islamic banks could make better marketing strategies and could increase their presence by mosque visits and conferences. Cooperation between the industry and scholars could help in providing more innovative products to the consumers.

There has been a limited amount of work carried out on the perceptions of consumers about Islamic banking in Pakistan. The present study represents the start of a larger context for examining Islamic banking practices in Pakistan. The findings of the study can be used as a reference in future research projects in the areas of perceptions and awareness.

Little research has been conducted to study this problem from the perspectives of consumers and Islamic banking employees. Most of the research associated with Islamic banks fails to pay attention to these stakeholder groups in one study.

The major goals of this study are to investigate the existing state of affairs concerning daylighting, glare and thermal comfort in the building, which will be the focus of the investigation, particularly in connection to the building’s energy efficiency considering student task performances. EnergyPlus, which is a software for building energy modeling, is applied to evaluate the energy consumption of buildings under a variety of circumstances related to their design. With the use of a variety of simulations, the goal of this study is to provide building design options that are both the most efficient and the most cost-effective for the case study building.

There are three distinct categories that can be applied throughout the entire process. The first thing that has to be done is to choose a building to use as a case study and then conduct an analysis of the current situation to address the existing problem. In the following step, several passive design measures are implemented and simulated in order to solve the challenges that are currently being faced. A detailed cost analysis is carried out as the final step in the process of determining whether or not it is feasible.

According to the findings: A cantilevered 3’ drop wall as a shading system, an east-facing model, and a window with a height of 4.5 is the ideal configuration. The annual energy can be saved by 22.5%. The payback period is 11 years. Benefit/Cost >1 makes it a feasible and economical solution.

The work is completely original. No one have done this before.

The purpose of this paper is to access the present situation of the Pakistani population that suffers from vitamin D deficiency.

A review-based study was conducted based on publications from Pakistan between the years 2008 and 2018. The publications were archived from Pub Med and Google Scholar databases. A total of 18 publications were shortlisted, based on the cutoff values of vitamin D sufficiency, insufficiency and deficiency.

As per the data, 38.5 per cent of the participants were males, 48.7 per cent were females and 12.8 per cent of the studies have not mentioned the genders of the participants. The cumulative results show that 58.17 per cent (95 per cent CI: 52.17, 64.16) of the population is vitamin D-deficient and 26.65 per cent (95 per cent CI: 21.63, 31.66) is insufficient in vitamin D. The highest level of vitamin D deficiency was reported from Sindh (62.15 per cent), followed by Khyber Pakhtunkhwa (60.57 per cent), Punjab (51.75 per cent) and the Federal Capital (49.25 per cent). Moreover, Cochran’s Q test indicated considerable heterogeneity (p = >0.001) with regard to Vitamin D deficiency (VDD) prevalence found among samples from the selected studies.

The present analysis suggests that more than half of the Pakistani population suffers from VDD, which, thus, should be considered as an epidemic and treated likewise.
