Auto-Platoon : Freight by example

The work introduces a bio-inspired leader-follower system based on an innovative mechanism proposed as software latching that aims to improve collaboration and coordination between a leader agent and the associated autonomous followers. The system utilizes software latching to establish real-time communication and synchronization between the leader and followers. A layered architecture is proposed, encompassing perception, decision-making, and control modules. Challenges such as uncertainty, dynamic environments, and communication latency are addressed using Deep learning and real-time data processing pipelines. The follower robot is equipped with sensors and communication modules that enable it to track and trace the agent of interest or avoid obstacles. The followers track the leader and dynamically avoid obstacles while maintaining a safe distance from it. The experimental results demonstrate the proposed system's effectiveness, making it a promising solution for achieving success in tasks that demand multi-robot systems capable of navigating complex dynamic environments

Enhancing Gerbera Micropropagation Efficiency and Genetic Fidelity through Cytokinin and Auxin Combination Strategies

The present investigation was carried out to assess the impact of 6-benzyladenine (BA) in conjunction with Indole-3-butyric acid (IBA) on gerbera explant establishment under micropropagation. Additionally, the effects of BA, either individually or in combination with Kinetin (KIN), on shoot proliferation in two Gerbera cultivars, namely Kormoran and Dolores was experimented too. Throughout the experiment, various morphological changes were documented occurring during these micropropagation phases and also monitored potential genetic alterations using SSR markers. The studies revealed that the combination of BA and IBA yielded exceptional results, achieving a 100% success rate in explant regeneration within the shortest time frame. Notably, when BA and IBA were applied at lower concentrations, the number of shoots generated was reduced. However, the most substantial proliferation of shoots was observed when the growth medium contained 4 mg of BA and 0.5 mg of IBA per litre. Furthermore, our investigation into genetic fidelity using SSR analysis revealed no detectable polymorphism between the mother plant and the micropropagated plantlets in both the Gerbera cultivars, affirming the reliability of the micropropagation method in preserving genetic consistency

Heat stress tolerance indices for identification of the heat tolerant wheat genotypes

Abstract Heat stress is one of the major challenges in wheat cultivation because it coincides with the flowering period and limits the crop productivity. This study was conducted for evaluation of 50 wheat genotypes to identify the heat stress tolerant genotypes for improvement of stress tolerance. All genotypes were cultivated for two consecutive years (2018–2020) under normal and late sown conditions. The results of the study revealed that the combined analysis of variance indicated significant variations among genotypes for all the studied stress indices. The reduction in mean grain yield of all genotypes under stress condition as compared to non-stress condition, indicating that the heat stress significantly affect the grain yield. The correlation analysis showed that the negative correlation of tolerance index and stress susceptibility percentage index with the grain yield of genotypes under heat stress condition (Ys) and a highly positive correlation of stress tolerance index, mean productivity, geometric mean, harmonic mean and mean relative performance with grain yield (Yp and Ys) under both conditions, helped accurately to identify the desirable genotypes. From the results obtained from principal component, biplot and cluster analysis, it was reported that HD 2967, WH 1249, HI 1617, WH 1202, WH 1021 and WH 1142 are suitable and good yielding genotypes under both conditions. Thus, above genotypes can be used for cultivation at high temperature or as genetic resources for introducing genetic variations in wheat genotypes to improve stress tolerance
