Using Reinforcement Learning in the Path Planning of Swarms of UAVs for the Photographic Capture of Terrains

The number of applications using unmanned aerial vehicles (UAVs) is increasing. The use of UAVs in swarms makes many operators see more advantages than the individual use of UAVs, thus reducing operational time and costs. The main objective of this work is to design a system that, using Reinforcement Learning (RL) and Artificial Neural Networks (ANNs) techniques, can obtain a good path for each UAV in the swarm and distribute the flight environment in such a way that the combination of the captured images is as simple as possible. To determine whether it is better to use a global ANN or multiple local ANNs, experiments have been done over the same map and with different numbers of UAVs at different altitudes. The results are measured based on the time taken to find a solution. The results show that the system works with any number of UAVs if the map is correctly partitioned. On the other hand, using local ANNs seems to be the option that can find solutions faster, ensuring better trajectories than using a single global network. There is no need to use additional map information other than the current state of the environment, like targets or distance maps.

Robust Control Design of Active Front-Wheel Steering on Low-Adhesion Road Surfaces

In order to improve the stability of vehicle steering on low-adhesion road surfaces, this paper designed a hybrid robust control strategy, H2/H∞, for active front-wheel steering (AFS) based on robust control theory. Firstly, we analyzed the influence of the sidewall stiffness and road adhesion coefficient of the tires on vehicle stability, through which we can study the wheel deflection characteristics of low-adhesion roads. Secondly, the reference yaw velocity of the vehicle was calculated using the three-degrees-of-freedom model as the reference model, through which, taking the norm H∞ as the objective function and the norm H2 as the limit to control the output, the hybrid robust control strategy H2/H∞ of the AFS system on a low-adhesion road surface was developed. Finally, the simulation experiment was carried out by the Simulink/CarSim co-simulation platform and a hardware-in-the-loop (HIL) experiment. In this paper, the results show that the AFS control strategy can improve the vehicle handling stability on low-adhesion road surfaces, and the controller has good path tracking performance and robustness.

Plasma-Conditioned Liquids as Anticancer Therapies In Vivo: Current State and Future Directions

Plasma-conditioned liquids (PCL) are gaining increasing attention in the medical field, especially in oncology, and translation to the clinics is advancing on a good path. This emerging technology involving cold plasmas has great potential as a therapeutic approach in cancer diseases, as PCL have been shown to selectively kill cancer cells by triggering apoptotic mechanisms without damaging healthy cells. In this context, PCL can be injected near the tumor or intratumorally, thereby allowing the treatment of malignant tumors located in internal organs that are not accessible for direct cold atmospheric plasma (CAP) treatment. Therefore, PCL constitutes a very interesting and minimally invasive alternative to direct CAP treatment in cancer therapy, avoiding surgeries and allowing multiple local administrations. As the field advances, it is progressively moving to the evaluation of the therapeutic effects of PCL in in vivo scenarios. Exciting developments are pushing forward the clinical translation of this novel therapy. However, there is still room for research, as the quantification and identification of reactive oxygen and nitrogen species (RONS) in in vivo conditions is not yet clarified, dosage regimens are highly variable among studies, and other more relevant in vivo models could be used. In this context, this work aims to present a critical review of the state of the field of PCL as anticancer agents applied in in vivo studies.

Fault Detection through Vibration Signal Analysis based on HSM with TRIPPY Classifier

A proficient fault detection model has to be sketched for detecting slight variations of the vibrating signal of rotating machine whereas the diagnosis process prominently stuck with the inefficient extraction of effectual features of a signal in reduced time. Existence of above stated hilarious issue results in the confinement of inventive Harmonized Swan Machine (HSM) based on the stochastic characteristics of swan, which could collect the RKC (RMS, Kurtosis, Crest factor) signal features for every instantaneous signal unit which eliminates noise thereby reducing pre-processing task which in turn lessens time consumption and at the end yields learned extracted faulty features. Accurate classification of faulty features can be accomplished by casting inimitable Trippy classifier which is designed based on selective predictive character of trippy fish which provokes a good path to provide accurate classification based on learned features. This responsible classifier collectively organises the RKC features of respective signal units and do accurate classification of faulty occurrences based on the features in less time.

The Cycle of Life in The Hundred Little Flames

India has a variety of cultures which are more common in South India. India's culture collectively refers to the thousands of unique and distinct cultures of all the religions and communities present in India. The languages, religions, dance, music, architecture, food and customs of India vary from one place to another within the country. Indian culture has often been described as a fusion of several cultures. It's a family story, a relationship and a friendship. Ayan unravels mysteries that surround his grandfather Gopal Shanker's life. The story is simple and revolves around the protagonist, Ayan, whose life is thrown into turmoil following an unfortunate incident at a party which he attends due to peer pressure. Ayan is the symbol of the Millennial, careless young man of today who is over-imaginative of life. However, when you come to its core, Religion, caste system and local traditions are reflected in the day-to-day life of the people. Each locality has its own traditional customs based on a particular religion and caste. While Indian culture is vast, there are not many books on the subject that are not well adapted to readers ' needs. Preeti Shenoy's "A Hundred Little Flames" among the few read-friendly books. Every Modern household has modern amenities, but in its relationship, family bond, etc., the truth is lacking. In India, people used to give the relationships and bonds more values. All those good factors are vanishing in the modern days. The author highlighted these situations of Indian families and systems of today. People forget about their parents when you age and send them to old age homes. A Hundred Little Flames is a gem of a novel that continues to attract the attention of its reader. A sequel with a twist on other characters maybe wouldn't be such a bad idea. How our values were, and what importance we neglect these days, and disregard, and tells us what Gopal and Rohini can teach us. The book enlightens us on a good path and brightens our lives like hundred little flames.
