A greater community of researchers widely studies fog computing as it reduces the massive data flow to the existing cloud-connected network and performs better for real-time systems that expect a quick response. As the fog layer plays a significant role in a fog-cloud system, all of the devices participating in fog computing must be balanced with appropriate load to upstretched the system performance. The proposed method is founded on a tree-based dynamic resources arrangement mechanism that refreshes the fog clusters created using Fuzzy C Mean (FCM) to increase the speed of resource allocation. With the help of Fuzzy rule-based load calculation and intra-cluster job allocation, the load inside the group is maintained. The system also has the facility of inter-cluster job forwarding, which works on demand. A novel load balancing strategy, Real-Time Flexi Forwarded Cluster Refreshing System (RTFRS) is proposed by which all the tasks can be handled efficiently within the fog cloud system. The proposed system is designed so that overall complexity is not upraised and becomes suitable for fog computing architecture with low processing capacity by maintaining the quality of service. Experimental results show that the proposed model outperforms standard methods and algorithms used in fog computing concerning average turnaround time, average waiting time, resource utilization, average failure rate, and the load on the gateway.

Recently, Building Information Modeling (BIM) has emerged as a new technology in the construction industry, which is gradually gaining popularity among stakeholders. Despite the importance of BIM, the literature review shows a gap in the evaluation of BIM applications in Iran. Therefore, the aim of the current research is to evaluate the applications of BIM in construction projects. Since the evaluation of the most appropriate option is a multi-criteria decision-making problem. Therefore, decision makers use preferences that are uncertain in evaluating options. Rough's theory, which is efficient in such conditions, is used. First, by using the concept of Rough's theory to transform the preferences of experts and the combined method of Analysis Hierarchy Process (AHP) and VIKOR, is used for evaluation. The results show that the proposed decision method is effective improved objectivity in BIM application evaluation under subjective condition.

Enthusiasm is one of the main psychological variables affecting the entrepreneurial intention of people, which as one of the dimensions of well-being in the work environment, expresses a positive and active feeling, which is known with a high level of work with interest and honor. The aim of the present research is to investigate the role of the entrepreneurial enthusiasm of managers in the organizational structure of managers of government organizations. According to the existing theoretical frameworks, the relationships between research variables have been evaluated by some quantitative methods. According to the characteristics of the statistical society, the non-probability and accessible sampling method was chosen for the experts. To determine convergent and divergent validity, Lisrel software was used, and for data analysis, the Kolmogorov-Smirnov test was usually used to test the normality of the data. The analysis of the obtained data showed that; GFI (normalized fit index) higher than 0.9 is a sign of a good fit of the model. RMSEA is equal to 0.055 (the root mean square of the error of approximation or the deviation test of each degree of freedom) and a value less than 0.08 indicates a good fit of the model. Shows, On the other hand, the P-value (significant level) is 0.0001, which is less than 0.05, so it is accepted with 95% confidence of the conceptual model of entrepreneurial enthusiasm of managers of public organizations. The results showed that the investigation of the entrepreneurial enthusiasm of managers of public organizations in Isfahan province showed factors such as organization atmosphere, perspective, and upstream documents, knowledge management in the organization, efficient human resources, and entrepreneurial culture in the organization, organizational learning, and entrepreneurial education. There is a desire for entrepreneurship in this.

The artistic background of the Good Shepherd motif can be traced to ancient eras of the East and the West. This motif later gained prominence in early Christian art. The ram-bearer (carrying a sacrificial or an offering animal) first appeared in Near Eastern art and later became an important motif in Greco-Roman art to represent certain roles of the god Hermes. This motif was considered by Christian converts as a symbol of Jesus Christ, as they represented him in the figure of a young shepherd caring for his flock. This theme can also be seen on some Sasanian seals, which can be considered as the Good Shepherd motif. In this article, the authors introduce the aforementioned motif depicted on these seals and examine their possible connection with the Christian communities. The motif of the Good Shepherd, as seen on the seals, demonstrates modifications in the original iconography. These changes can be observed in the longer dress of the ram-bearer or the engraving of celestial symbols. These modifications are probably a sign of the localization process of an imported motif in the Sasanian Empire.

This paper deals with an old Judeo-Persian letter called Dandān-Uiliq II (Abbreviated as DU II); which probably dates back to 9th century CE and further to its contents, has some important linguistic features, often without existence in later Persian texts written in Arabic script, for instance, the use of the adverb bē = but (as in Qur’an-e Qods translation), use of the conjunction kū, the use of the verb h- (to be) and ancient subjunctive mood. This paper also presents a new translation of the letter and its ancient linguistic features discussed in comparison to Early Persian texts (in Perso-Arabic script) and some early Persian translations of Qur’an, especially Qur’an-e Quds (probably written in Sistan in 12th CE). These features represent language transmission from Middle Persian to Neo-Persian (Dari). The given translation is not the same as previous English and Chinese versions and reflects my understanding of its syntax and morphology.
