New efficient GAF routing protocol using an optimized weighted sum model in WSN

<span>A wireless sensor network (WSN) composed by a large number of sensor nodes that are insufficient in terms of processing power, storage and energy. The principal tasks of nodes is gathering and transmitting data collected to the base station (BS). Consequently the major essential criteria for designing a WSN are the network lifetime. In this paper an efficient GAF routing protocol for gathered data is introduced. It proposes an energy-efficient routing in WSN based on the basic version. In this system sensor nodes are distributed using Gaussian law and an active leader is elected for each virtual grid to reduce the energy dissipated using an optimized weighted sum model where maximum remaining energy and minimum distance criteria are considered. Moreover routing data is based on transmission range for enhancing the energy efficiency during data routing. The experimental results shows that the proposed EE-GAF produces better performance than the existing GAF basic and optimized-GAF routing protocol in terms of number of dead node and energy consumption. It is obviously proves that the proposed EE-GAF can improve the network lifetime</span>

Towards an Abrahamic Religion: Developments in Later Meccan Suras. Part II: Abraham, Local Heritage, and Developments in Liturgy and Ethics

Recent Qur'anic scholarship emphasises a distinction between a Meccan and a Medinan Qur'an. In addition to the doctrinal and literary particularities that set Medinan suras apart, scholars underline the failure of Muḥammad to convert his people and the despair exhibited by his followers in Later Meccan suras. In contrast, the Medinan suras depict a successful, socially and politically engaged leader of a growing and strong religious community. This paper addresses literary and content-related developments in Later Meccan suras and demonstrates that our perceptions of a passive messenger in Mecca and an active leader in Medina, and of the emergence of a self-assured community only in Medina, have to be reconsidered. Later Meccan suras depict a contest over the interpretative dominance of the empirical world which ultimately strengthens the authority of Muḥammad and consolidates the emerging group of Followers. They exhibit intertwined developments of literary strategies such as argumentation patterns or parabolic speech, and intensive reflections on notions such as perception and knowledge. Whereas the first part of this paper examines these processes, the second part focusses on the growing importance of the figure of Abraham, a decisive turn to local heritage and the development of liturgical formulas and ethical norms. The exploration and understanding of these textual dynamics are indispensable for understanding the genesis of both Meccan and Medinan suras.

Innovative and motivational competence of leaders and its transformation in the context of digitalization

The main factor that affected changing competencies in modern conditions is digitalization; the necessity of the interconnected development of innovative and motivational competence of managers is substantiated. The goal of this article is to highlight the most important characteristics of the innovative and motivational competence of organizational leaders. To analyze the competence factors, hypotheses about their change were made, which were tested using two methods: a sociological survey to assess the competencies priority and pairwise comparisons of competency characteristics in terms of their impact on the innovative activity of organizations. The competency model of a modern, innovatively active leader was formed, which included: psychological readiness for change and constant selfdevelopment, a desire to lead the organization to success, the need to be a leader based on innovative style of behavior, knowledge of advanced achievements in the organization's field of activity, experience in introducing inventions, skills to attract investment, understanding the risks of improvement. Our assumptions about the transformation of the leaders’ competencies are confirmed. However, estimates of the competencies shift towards motivational components were less significant than expected. Nevertheless, in the context of digitalization, it is very important for innovative leaders to constantly improve their motivational competencies in order to stimulate there highly professional creative workers who create and implement innovations.

Consensus Design for Heterogeneous Battery Energy Storage Systems with Droop Control Considering Geographical Factor

This paper proposes a hierarchical control strategy to coordinate battery energy storage devices based on a multi-agent system. The heterogeneous nature of the battery volume is paid much more attention in designing the proportional protocol of the consensus controller. Besides that, a cluster algorithm based on Minimum Spanning Tree (MST) is suggested to represent geographical factor, and on account of that, each Battery Energy Storage System (BESS) is classified into its specific cluster zone. Further, an active leader is assigned to be in charge of information from the external side in every cluster. The consensus algorithm reconciles all clusters in a step-by-step way. Energy level, voltage, frequency and active/reactive power sharing of every BESS can reach consensus by an information exchange within and among clusters respectively. Further, a virtual leader is taken into the active leader role in directing frequency and voltage to the reference values. To verify the consensus algorithm, a modified IEEE 57-bus is employed for time-domain simulations in an islanded mode and all BESSs are working in a discharge model.
