Diversity information mining about a crop for different attributes is an essential step for effective breeding programs. The present investigation evaluates the quantum of genetic variability and determines the relationship among the important agro-economic traits based on two years of phenotypic data of 210 accessions of linseed. The traits, capsule weight per plant, capsule per plant, husk weight per plant, and seed weight per plant exhibited comparatively higher genetic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV). In contrast, oil content and seed per capsule exhibited a lower value. The high magnitude of broad sense heritability was observed for all traits except seeds per capsule and husk weight per plant. The trait, capsules per plant, plant height, and days to 50% flowering showed high genetic advance coupled with high heritability. Hierarchical cluster analysis grouped 210 accessions into six distinct clusters. Out of 210, 144 (68.57%) accessions were grouped into three clusters (I, II, and III), in which cluster-III was the largest, containing 64 accessions followed by cluster II and cluster-I. The highest inter-cluster distance was observed between clusters-I and V (127.85), while the lowest was between clusters-II and IV (27.09). The positive correlation of capsule weight per plant with the seed weight per plant and a negative correlation with the days to 50% flowering indicates that high yielding linseed varieties with early flowering/maturity could be developed through direct and indirect selection. Further, seed yield and oil content could be enhanced together as indicated by ghe positive association among these two important traits. In this study, high yielding accessions with moderate to high oil content such as GP36, GP31, GP14, GP54, GP26, GP24, GP34, GP21, GP37 and GP27 and early flowering (less than 70 days) accessions such as GP2, GP26, GP27, CG33, CG44, CG42, CG132, and CG31 identified as potential genetic mater

Traffic Engineering and Quality of service in Hybrid software Defined Networks

China Communications 2024年第2期21卷 96-121页

作者： samiullah Mehraban Rajesh kumar yadav IOT Lab Department of Computer Science&EngineeringDelhi Technological UniversityDelhi 110042India

For Future networks, many research projects have proposed different architectures around the globe;software Defined Network(sDN) architectures, through separating Data and Control Layers, offer a crucial structure for it. With a worldwide view and centralized Control, the sDN network provides flexible and reliable network management that improves network throughput and increases link utilization. In addition, it supports an innovative flow scheduling system to help advance Traffic Engineering(TE). For Medium and large-scale networks migrating directly from a legacy network to an sDN Network seems more complicated & even impossible, as there are High potential challenges, including technical, financial, security, shortage of standards, and quality of service degradation challenges. These challenges cause the birth and pave the ground for Hybrid sDN networks, where sDN devices coexist with traditional network devices. This study explores a Hybrid sDN network’s Traffic Engineering and Quality of services Issues. Quality of service is described by network characteristics such as latency, jitter, loss, bandwidth,and network link utilization, using industry standards and mechanisms in a Hybrid sDN Network. We have organized the related studies in a way that the Quality of service may gain the most benefit from the concept of Hybrid sDN networks using different algorithms and mechanisms: Deep Reinforcement Learning(DRL), Heuristic algorithm, k path partition algorithm, Genetic algorithm, sOTE algorithm, ROAR method, and Routing Optimization with different optimization mechanisms that help to ensure high-quality performance in a Hybrid sDN Network.

Graphene derivatives as efficient hole transport materials for lead-free double perovskite(CssnI) solar cells: a numerical study

引用

Optoelectronics Letters 2024年

作者： sARITA yadav sARAL k GUPTA C.M.s.NEGI Department of Physical science，Banasthali Vidyapith

The double perovskite Cs2snI6has notable optical and electrical characteristics， rendering it a highly prospective candidate for deployment as the absorber layer in perovskite solar cells (PsCs). We simulated the performance of PsCs using lead-free Cs2snI6double perovskite absorber layer and graphene derivatives， namely graphene oxide (GO) and reduced graphene oxide (rGO)， as hole transport layers (HTLs). Our findings show that rGO offers an excellent hole extraction property with minimal interfacial recombination compared to GO. PsC utilizing rGO as the HTL material achieved a power conversion efficiency of 19.07%， while those employing GO HTL attained only 16.9%. The superior performance of rGO is attributed to its greater charge carrier mobility of rGO and its favorable energy level alignment with the double perovskite absorber layer. In contrast， the mismatch in the charge transport properties between the absorber layer and the GO HTL resulted in poor performance. Our study showcases the potential of using graphene derivative-based HTLs for realizing lead-free PsCs.
