In artificial intelligence, the optical character recognition (OCR) is an active research area based on famous applications such as automation and transformation of printed documents into machine-readable text document. The major purpose of OCR in academia and banks is to achieve a significant performance to save storage space.

A novel technique is proposed for automated OCR based on multi-properties features fusion and selection. The features are fused using serially formulation and output passed to partial least square (PLS) based selection method. The selection is done based on the entropy fitness function. The final features are classified by an ensemble classifier.

The presented method was extensively tested on two datasets such as the authors proposed and Chars74k benchmark and achieved an accuracy of 91.2 and 99.9%. Comparing the results with existing techniques, it is found that the proposed method gives improved performance.

The technique presented in this work will help for license plate recognition and text conversion from a printed document to machine-readable.

The goal of this study was to examine the mediating mechanism of informal learning between dimensions of learning climate and organizational citizenship behavior (OCB). In addition, the study also aimed to investigate the learning climate, in the dimensions of learning facilitation, learning appreciation and error avoidance as antecedents of informal learning.

The data were gathered from sports items manufacturing small and medium enterprises (SMEs) in Sialkot, Pakistan. Sialkot is home to manufacturing businesses that export their products worldwide. Survey data of 318 middle managers collected at 2 different times were used for testing the research model using structural equation modeling (SEM).

The results demonstrate that facilitation and appreciation learning climate have a positive relationship with informal learning and error-avoidance has a negative relationship with informal learning. The analysis also revealed that informal learning mediated the linkage between learning climate dimensions and OCB. Moreover, informal learning is significantly related to OCB.

HR practitioners and organizational leaders of SMEs can use, encourage and promote informal learning to improve the skills and knowledge of employees at low cost. For instance, management should strategically implement informal learning at the workplace by providing a supportive learning climate.

Previous studies have overlooked the impact of informal learning on OCB and its mediating effect. The present study addresses this gap by examining the mediating mechanism of informal learning between learning climate and OCB.

Naturally, all the materials are not viscous (i.e. milk, mayonnaise, blood, vaccines, syrups, cosmetics, oil reservoirs, paints, etc.). Here present analysis focuses on the usage of non-Newtonian fluid rheological properties enhancing, damping tools, protection apparatus individuals and in various distinct mechanical procedures. Industrial applications of non-Newtonian liquids include minimum friction, reduction in oil-pipeline friction, scale-up, flow tracers and in several others. The peristaltic mechanism is used as a non-Newtonian material carrier here. This mechanism occurs because of continuous symmetrical and asymmetrical propulsion of smooth channel walls. Peristalsis is a very significant mechanism for carrying drugs and other materials during sensitive diseases treatments.

Keeping in mind the considered problem assumptions (Rabinowitsch fluid model, thermal Grashof number, Prandtl number, density Grashof number, wall properties, etc.), it is found that the modeled equations are coupled and nonlinear. Thus here, analytical results are quite challenging to acquire and very limited to extremely venerated circumstances unsettled to their nonlinearity. Hence various developments found in computing proficiencies, numerical procedures that provides accurate, stable and satisfying solutions for non-Newtonian material flows exclusively in complex dimensions play a significant role. Here BVP4C numerical technique is developed to evaluate the nonlinear coupled system of equations with appropriate boundary constraints.

Due to convectively heated surface fluid between the walls having a small temperature. Sherwood and Nusselt numbers both deduce for fixed radiation values and different Rabinowitsch fluid quantity. Skin friction is maximum in the case of Newtonian, while minimum in case of dilatant model and pseudoplastic models. The influence of numerous parameters associated with flow problems such as thermal Grashof number, density Grashof number, Hartman number, Brownian motion, thermophoresis motion factor and slip parameters are also explored in detail and plotted for concentration profile, temperature distribution and velocity. From this analysis, it is concluded that velocity escalates for larger

The perception of Islamic finance by its various stakeholders is not always reconcilable. Its foundations and attributes are subject to a plurality of perceptions making it almost impossible to reach a consensus about them. This paper aims to understand the perception of Islamic finance by bank employees in Cameroon.

This research follows the interpretativist paradigm and is qualitative and exploratory in nature. The data are collected through semi-structured face-to-face interviews with bank employees, mainly branch managers. These interview data are analysed using the thematic analysis method.

Bank employees in Cameroon perceive Islamic finance as a finance that: targets everyone, regardless of religion, but Muslims first (Islamic finance is both inclusive and exclusive); offers original products and services; has a religious anchor that may hinder non-Muslim economic agents; has many advantages, mainly for financial institutions, and some limitations for financial institutions and their customers; is full of opportunities for its stakeholders; and is not yet fully practiced in Cameroon.

This study mobilises a qualitative approach, provides new insights into the research on the perception of Islamic finance and reaches a consensus on the perception of certain aspects and attributes of Islamic finance, namely, for the perception of the target and the Shariah compliance of Islamic finance. Furthermore, this study is a pioneering effort to understand bank employees’ perception of Islamic finance in non-Islamic and developing countries where Islamic finance is underdeveloped.

The purpose of this paper is to advance the theoretical perspective of complexity leadership paradigm to introduce shared leadership style as a precursor of taking charge behavior in public sector higher educational institutions (HEIs) of Pakistan. Moreover, this study unveils the underlying mechanisms of the climate of initiative and psychological safety for clarifying the link of shared leadership and taking charge.

The multi-source and multi-wave data were analyzed by employing double mediation analysis (PROCESS Model 4); using 282 valid responses obtained from a proportionate stratified sample of faculty members working in public sector HEIs of Pakistan.

The result indicates that shared leadership is a suitable style for governing the public sector HEIs and it fosters taking charge behavior in teaching faculty. Additionally, shared leadership creates climates that support initiatives and are psychologically safe that set stage for taking charge behaviors in teaching faculty of public sector HEIs of Pakistan.

This research has filled the gap of focusing on more collaborative leadership styles instead of traditional vertical leadership practices in public sector HEIs of Pakistan. Theoretically, this study suggests new insights into the contextual antecedents and mediating mechanisms of taking charge behaviors.

This work aims to increase the dyeability of nylon 6 with basic dyeing through the treatment of the fibre with available and cheap nanomaterials, namely; nano bentonite using an economic and simple method.

Different amounts of nano clay, namely, nano bentonite were dispersed in distilled water using an ultrasonic homogenizer for 1 h. Nylon fabrics were treated with different concentrations of dispersed nano bentonite (1%, 2%, 3%, 4%, 5% wt/v). After half an hour, the samples were padded using SVETEMA laboratory padding system. The padding pressure was adjusted at 3 bar to allow a pickup of 100%. The padded samples were dried at 80°C for 5 min and cured at 160°C for 3 min using ROACHES laboratory thermos-fixation. The cured samples were then washed with running water and left to dry at room temperature.

The obtained results indicated that the modification of polyamide 6 fibres with nano bentonite had a great impact on their dyeing properties. The obtained shades, absorption behaviour and fastness properties were significantly enhanced. Based on these results, it was concluded that polyamide fabrics could be successfully dyed with basic dyes using economical dyeing conditions.

This paper introduces a new method the loaded the nano-clay on the synthetic fibres, which are nylon 6 to enhance the dyeability with cationic dyes using the physical method without changing the structure of the fibres.

Knowledge is considered an asset for any organization. To distribute knowledge and expertise among stakeholders of an organization, there is a need to develop knowledge sharing (KS) culture. However, different factors affect KS. This study aims to identify the influence of trustworthiness (trust, ability, benevolence and integrity) and motivation and reward on KS attitudes and intentions of law students.

The objectives of the study were achieved by using a quantitative research design. Law students of the colleges affiliated with Punjab University were the population for the present research. The sampling frame of the study was all law colleges, and data was collected through a convenient sampling technique. Data was collected through personal visits to sampled colleges. Questionnaires were circulated among 330 respondents and two hundred valid responses were collected with a 61% response rate. Descriptive analysis was completed using SPSS and path analysis was measured through SmartPLS. The quality of the measurement model was assessed and then hypotheses were tested.

Findings revealed that there was no impact of trustworthiness (trust, ability, benevolence and integrity) on the KS attitude of students. However, motivation and rewards significantly impacted (ß = 0.590; p > 0.01) the KS attitudes. KS attitude also has a significant impact on KS intentions (ß = 0.560; p > 0.01).

The current study is a valuable addition to the literature by providing the impact of trustworthiness, motivation and reward on law students’ KS intentions and attitudes in developing countries. The present study also provides insights for authorities and decision-makers in making decisions regarding the development of KS among students.

This study aimed at exploring the change facilitator styles (CFS) that secondary school head teachers in Pakistan possess.

This is a quantitative study using Hall and George CFS questionnaire to collect data from 276 secondary school head teachers. The CFSQ used in this study consists of 30 Likert-type questions relating to six scales. The six scales, with five items each in aggregate, form three possible CFS, including initiator, manager and responder.

The results indicate that most secondary school head teachers (75.7%) in Pakistan used responder CFS to facilitate change in their schools. 16.7% of the head teachers used manger, while only 7.6% possessed initiator change facilitation styles.

The study has implications for research, in particular in the developing countries where head teachers' leadership practices are rooted in the past with maintaining authority and status quo.

The study has implications for policymakers and schools in developing countries, like Pakistan, in terms of considering the vital role of head teachers in change implementation. In particular, in the prevailing cluster-based educational management, the study's findings remain valuable for schools in the Balochistan province of Pakistan.

The paper reports the results regarding secondary school head teachers' change facilitator styles in the context of power devolution in Pakistan. The authors believe that the manuscript is appropriate for publication by the international journal of educational management because it is in line with the aims and scope of the journal. The authors assure the originality of this work. It has not been published elsewhere, nor is it currently under consideration for publication in any other journal.
