A multi-state linear k-within-(r, s)-of-(m, n): F lattice system consists of m×n components arranged in m rows and n columns. The possible states of the system and its components are: 0, 1, 2, …, H. According to k values, the system can be categorized into three special cases: decreasing, increasing and constant. The system reliability of decreasing and constant cases exists. The purpose of this paper is to evaluate the system reliability in increasing case with i.i.d components, where there is no any algorithm for evaluating the system reliability in this case.

The Boole-Bonferroni bounds were applied for evaluating the reliability of many systems. In this paper, the author reformulated the second-order Boole-Bonferroni bounds to be suitable for the evaluation of the multi-state system reliability. And the author applied these bounds for deriving the lower bound and upper bound of increasing multi-state linear k-within-(r, s)-of-(m, n): F lattice system.

An illustrated example of the proposed bounds and many numerical examples are given. The author tested these examples and concluded the cases that make the new bounds are sharper.

In this paper, the author considered an important and complex system, the multi-state linear k-within-(r, s)-of-(m, n): F lattice system; it is a model for many applications, for example, telecommunication, radar detection, oil pipeline, mobile communications, inspection procedures and series of microwave towers systems.

This paper suggests a method for the computation of the bounds of increasing multi-state linear k-within-(r,s)-of-(m,n): F lattice system. Furthermore, the author concluded that the cases that make these bounds are sharper.

The purpose of this paper is to draw a map of the general features of epistemological and critical concerns in contemporary Islamic philosophy. This study will not be confined to the domain of academic philosophy or to those who are professionals in the field of philosophy.

The paper adopted the critical rational approach in dealing with contemporary Islamic philosophy in the Arab world. The scope will include scholars from different fields of epistemology who tried to present a “vision” of the attitude that should be adopted in facing the challenges of the age and the problems of the nation on the epistemological level or the political, economic and social levels.

There is a need for a philosophy of action and progress rather than a philosophy that is based on abstract ideas and theories and of words/rhetoric. The ethics required to accomplish this ought to identify the attributes of the citizen who can reach self-actualization through legitimate means based on a progress agenda with theoretical and philosophical foundations.

Because a critical rational approach can be dealt with from different perspectives, this paper will adopt the classification of the principal intellectual trends: the reformist, secular and liberal.

This paper covers a long time span to determine whether the philosophical projects have been effective.

This paper, which criticizes the philosophic projects that are theoretically unsound and that do not address real social problems (like poverty), argues the need for a philosophy of progress and action. This will lead to devising an agenda that addresses the challenges the society is facing and to finding alternative and creative solutions resulting in development.

This study aims to explore commonalities and differences between Islamic social finance (ISF) and sustainable development goals (SDGs).

The study has adopted a qualitative library-based research method, and the secondary data is collected through the available literature on the topic.

This study concludes that the majority of SDGs are compatible with ISF. Moreover, it finds that the global ISF possesses adequate financial resources to assist Muslim majority nations in achieving some of the most critical and urgent SDGs on time.

The scope of this study is confined to examining the possible role of ISF in achieving many of the most pressing development goals aligned with the SDGs. To maintain coherence within the study’s focus, this paper makes no comparisons between the ISF and other types of endowments/charities.

This paper outlines an agenda for the ISF-led development strategy and makes some crucial recommendations on how the global ISF might potentially lead the charge of Islamic charities in achieving the SDGs in Muslim majority nations.

This paper adds original value to the available literature on the potential of ISF and SDGs in the arena of development. The paper analyses the role of ISF in achieving the SDGs.

The increasing number of papers on zakah shows that it has become an important research topic. However, few studies attempt to analyze the evolution of zakah studies which might be helpful as guidance for policymakers in creating zakah management systems and policies, for zakah management organizations administering zakah funds, for future research on related subjects and for academic actors to construct a zakah study curriculum. This study aims to conduct a bibliometric analysis of the evolution of zakah theme publications from 1964 to 2021.

This study uses bibliometric analysis to analyze the evolution of zakah research. This study compared all Scopus-indexed journal papers to Zakah publications regarding research flow, themes, abstracts and titles. The relationships between researchers, the titles of the papers and keywords associated with “zakah” are analyzed in these publications published between 1964 and 2021. A total of 632 scientific contributions were discovered using RStudio and VOSviewer to analyze the bibliometric metadata.

Based on the results, the theme of zakah has evolved from 1964 to 2021. The author emphasizes the zakah publication theme. Each affiliation and country have its conditions, management method, data sources and characteristics. The theme “zakah institutions and zakah collecting” grew in popularity between 2010 and 2021 and is projected to grow in the following years. Malaysia, Indonesia and Pakistan can be used as zakah development research models. In spans of zakah publications, the author with the most global citations is Wahab N.A., and the author with the most productive is Saad Raj.

Zakah publications are analyzed using the Scopus database. This study applied only Scopus index data, excluding non-Scopus, and most studies conducted in non-English languages. This conclusion indicates the issue’s importance among academic researchers and practitioners, notably on the subject of zakah. Thus, a comprehensive picture of zakah theme publications assists researchers and zakah fund institutions in making assessments, focusing on the unstudied fraction of the zakah theme.

This research is planned to serve as a reference for future research, particularly examining the theme’s novelty. It is intended to have implications for policymakers, particularly zakah institutions, regarding funding the several zakah research issues and concentrations.

This research can guide future researchers and is expected to include parameters such as author, year and data source while analyzing zakah publications to generate new findings.

This is probably one of few comprehensive studies that examined the evolution of the zakah theme using the Scopus-indexed database. The relevance of this paper is to provide suggestions and projections for future zakah research. Scholars should examine zakah publications by author, year and data source to gain fresh insights. Search for data sources with high-impact factors and objective metrics, then clear out irrelevant documents to improve the analysis’ quality and findings.

The study investigates the effectiveness of an adaptive reflective framework that shifts the learning process toward a student-centered approach within an interdisciplinary learning environment. It aims to promote the learning process within an interdisciplinary learning environment that could promote the students’ design competencies.

The experiment was conducted at Basic Design studio, investigating three concepts of basic design principles: harmony, repetition and rhythm. A total of 80 first-year architectural students were enrolled in this study and placed into two equal groups: the “control group” received the traditional learning method and in contrast, the “experimental group” received an interdisciplinary reflective learning method using music as a relevant discipline.

The results showed that utilizing “Music Animation Machine” in the learning process significantly promoted students’ cognitive skills, engagement and design competencies. In addition, there was obvious evidence of excellent progress in learning basic design principles using the proposed reflective approach within a student-centered learning environment.

Many researchers focus on the importance of using music as a design tool. However, there is a crucial demand for investigating it as a learning tool. This research raised music effectiveness in the learning process of design principles. Thus, it incites to test more disciplines interconnected with architectural design. Other researchers could utilize this approach to ensure its effect on enhancing design competencies in the basic design and other architectural design courses.

This paper aims to investigate the performance of four different textile materials used as an outer shell of the bulletproof vest.

In this paper, four different textile materials were used, polyurethane treatment was applied as a surface coating for the woven samples. Mechanical properties were conducted for all samples; scanning electron microscope and X-ray energy disperse spectroscopy were executed to show the surface morphology of samples and the chemical composition of the coating material.

One-way ANOVA was used to statistically analyse the results, which proved that all variables were highly significantly affected by using different textile materials, despite the stiffness variable being not significantly affected by textile materials. An overall evaluation was done using radar chart, demonstrated that Cordura material accomplished the best functional performance, using two types of calibres 7.62 × 54 mild steel core and 7.62 × 54 armour piercing incendiary; the common mechanism was localized burn because of the incendiary effect of the projectile in addition to tearing mechanism starting from inside because of penetration effect of the steel core.

This work was addressed to analyse the impact of using four different materials on its performance as the outer shell of bulletproof vest to achieve the desired degree of protection.

The inevitable change orders in construction projects have either direct or indirect impacts on a project’s duration. Reduced productivity is one of the indirect consequences that lead to major delays in the completion of the project. The purpose of this study is to develop a model that could quantify the impact of change orders on labor productivity and result in the establishment of policies to lessen their effects.

A model was developed to analyze the effects of change orders on labor productivity, then policies for managing their impacts on productivity and project duration were established. A water treatment case study was selected to serve as the scenario in which to implement and evaluate the model and policies.

The results of this study indicated that pressure to adhere to a schedule initially leads to an increase in labor productivity, but it is often followed by a significant drop that is a result of employee frustration. It was concluded that the pressure can be positive if it is applied for a short period of time; however, it continues for a significant length of time, the duration of the project will increase appreciably.

The proposed model can be implemented to identify the factors that affect labor productivity in a construction project. Its utilization will also help project managers assess when change orders occur and determine, which policies will be most effective in optimizing labor productivity.

Change orders in construction projects may lead to an increase in time and cost highlighting the need for a systematic analysis of the causes of change orders. Each cause of change orders has a probability of occurrence and impact; therefore, there is a need to reassess the causes of change orders based on the probability and impact. The purpose of this paper is to determine the risk score for each factor and develop a model for estimating the overall change orders based on the measured and latent variables.

The research methodology consists of four parts. The first part identifies the causes of change orders in road projects from a literature review and develops the final list using the Delphi technique. The second part includes designing the final questionnaire to determine the probability and impact of each factor on the five-point Likert scale and 237 questionnaires received validity. The data were divided into training and testing sets and analyzed using AMOS software.

The proposed structural equation model presents an insight into the influence of measured and latent factors, which are not obvious in the traditional equations. The main cause for change orders was a change in design.

The results of this research are expected to improve the execution of road projects by identifying the main causes of the change orders and hence the project manager can develop a proper risk response plan.
