A Multi-Ray Channel Modelling Approach to Enhance UAV Communications in Networked Airspace
No full textIn recent years, the use of unmanned aerial vehicles (UAVs), commonly known as drones, has significantly surged across civil, military, and commercial sectors. Ensuring reliable and efficient communication between UAVs and between UAVs and base stations is challenging due to dynamic factors such as altitude, mobility, environmental obstacles, and atmospheric conditions, which existing communication models fail to address fully. This paper presents a multi-ray channel model that captures the complexities of the airspace network, applicable to both ground-to-air (G2A) and air-to-air (A2A) communications to ensure reliability and efficiency within the network. The model outperforms conventional line-of-sight assumptions by integrating multiple rays to reflect the multipath transmission of UAVs. The multi-ray channel model considers UAV flights’ dynamic and 3-D nature and the conditions in which UAVs typically operate, including urban, suburban, and rural environments. A technique that calculates the received power at a target UAV within a networked airspace is also proposed, utilizing the reflective characteristics of UAV surfaces along with the multi-ray channel model. The developed multi-ray channel model further facilitates the characterization and performance evaluation of G2A and A2A communications. Additionally, this paper explores the effects of various factors, such as altitude, the number of UAVs, and the spatial separation between them on the power received by the target UAV. The simulation outcomes are validated by empirical data and existing theoretical models, providing comprehensive insight into the proposed channel modelling technique

A comprehensive study on evaluating effective cracked stiffness of Engineered cementitious composite (ECC): Experimental findings and proposed stiffness modifiers
No full textEngineered cementitious composites (ECC) have emerged as a promising alternative to conventional Reinforced cement concrete (RCC) due to their unique micro-crack bridging and tension hardening properties. These characteristics enable ECC to exhibit superior ductility, damage tolerance, durability, and greater stiffness. Despite the numerous advantages of ECC, its widespread adoption in the construction industry has been hindered by the need for comprehensive design guidelines and the reliance on stiffness modifiers (k) derived from RCC. This study determines the effective section stiffness (ESS) of ECC and proposes a k value for ECC beams. For the evaluation of ESS, 27 rectangular beams with various cross-section sizes (aspect ratios-h/b), reinforcement ratios (rho%), and compressive strength (fc<acute accent>) of ECC were considered. Moment curvature (M-& empty;) curves were obtained and idealized to bi-linear form to calculate ESS and k factor. The results reveal that the rho%, fc<acute accent>, and h/b ratio significantly influence the ESS of ECC members. For instance, with constant fc<acute accent>(55 MPa) and h/b (2), as the rho% increases from 1.25 % to 1.5 % and then to 1.75 %, the corresponding k factor increases from 0.49 to 0.509 and subsequently to 0.531. Also, with constant rho% (1.75 %) and h/b ratio (2), as the fc<acute accent> increases from 35 MPa to 45 MPa and then to 55 MPa, the k factor increases from 0.506 to 0.513 and then 0.531 respectively. However, no clear trend was noticed with increase in rho%, as the value of the k factor increases and then decreases again. Ultimately, the mean k value determined for ECC (0.467) is 33.4 % higher compared to RCC (0.35). By addressing the current limitations in the design guidelines for ECC, this research has the potential to promote the widespread use of this innovative material in the construction industry, leading to more resilient, sustainable, and cost-effective infrastructure.
Enhancing wheat performance through phosphorus and zinc management strategies under varied irrigation regimes
No full textThis study addresses the critical role of phosphorus and zinc applications in enhancing wheat productivity and profitability under varying water availability. While the individual impacts of phosphorus and zinc on crop nutrition are well-established, their combined effect remains underexplored, particularly in moisture-stress environments. This research aims to optimize wheat production using varying irrigation regimes. A randomized complete block design with three replications was used to investigate the effects of phosphorus and zinc applications. Phosphorus was applied at three levels (50, 75, and 100 kg ha− 1 as DAP), and zinc at three levels (5, 10, and 15 kg ha− 1 as ZnSO4), under two irrigation Methods: limited irrigation and full irrigation. Evaluation parameters included phenological stages, growth parameters, yield, and economic analysis. The study identifies that the combination of 100 kg P ha− 1 and 15 kg Zn ha− 1 maximizes wheat productivity, with significant improvements in various yield components and economic metrics. Full irrigation consistently outperformed limited irrigation in terms of yield and yield components. Principal component analysis confirmed the beneficial effect of combined phosphorus and zinc applications on wheat productivity. The cost-effectiveness, determined by the benefit-cost ratio, supports recommending the application of P100 + Zn15 to enhance wheat productivity and profitability in both full and limited irrigation scenarios. Farmers in similar agro-ecological regions will directly benefit from these findings by achieving higher yields and better economic returns. The industrial importance is highlighted by the potential for increased wheat production and improved financial viability for farmers, suggesting significant advancements in sustainable agricultural practices for water-scarce regions
