"Multi-UAVs Network Design Algorithms for Computed Rate Maximization" by Kefeng Wu, Kwan Wu Chin et al.

This paper considers a network design problem using Unmanned Aerial Vehicles (UAVs). It aims to create a network to provide communication and computation service to a set of source-destination ground node pairs. The main performance metric is the minimum amount of computed data among a set of source-destination pairs. To optimize this metric, we outline two mixed Integer Linear Programs (MILPs), namely S-MILP and NS-MILP, which are designed respectively for splittable and non-splittable traffic flow models. They jointly optimize the placement of UAVs, assignment of Virtualized Network Functions (VNFs), and routing of unprocessed and processed flow. Further, NS-MILP optimizes the path selection of each source-destination pair. A key challenge is that these MILPs require an exhaustive collection of network topologies. To this end, this paper outlines two heuristic algorithms, called Resource-Aware Location Selection (RALS) and Resource-Aware Path and Location Selection (RAPLS), respectiv ....

"Understanding the salient features related to resource management in b" by Ramkumar Jayaraman, Devandar Rao et al.

In recent days, Wireless technologies are improving drastically based on the number of users, leading to network traffic and reliability in the data services. Here the resource plays a significant role, and it needs various approaches to manage and monitor those resource mesh networks. As the network is concerned, different structure/topology is applied as the framework, and mesh topology is used in recent networking technologies. The various scheduling approaches are discussed based on the vast resource in the network. Then different characteristics are discussed related to radio channels based on wireless broadband networks and to provide effective network traffic management and Quality of Service. As advanced networks is concern, network coding approaches are considered while the data are exchanged between the nodes in the network. Finally, the various parameters are discussed related to resource and channel management to provide effective communication in the network. ....

"A Novel Single Capacitor-Based T-Type Bidirectional Converter with Buc" by Shivam Prakash Gautam, Manish Kumar Barwar et al.

This paper introduces a novel bidirectional switched-capacitor converter topology with buck-boost capabilities. Unlike traditional T-type inverters that use two capacitors, the proposed topology utilizes only a single capacitor, reducing the number of capacitors by 50%. Normal, buck, and boost modes make the topology versatile for various applications. It can be used as a three-phase two-level or three-level inverter in all modes. A switched capacitor unit boosts the input voltage without requiring boost inductors or filter capacitors. This not only increases the DC link voltage but also boosts the power throughput without an increase in current which is a significant advantage in power electronics. The proposed topology controls switched capacitor unit inrush current with a soft-starting circuit. The buck mode operation is achieved by connecting a capacitor whose voltage is maintained at half the DC link voltage, resulting in a superior output voltage quality with reduced total harmon ....
