    This research delves into the realm of quadrupedal robotics, focusing on the comparative analysis of Model Predictive Control (MPC) and Reinforcement Learning (RL) as predominant control strategies. Through the comprehensive dataset compiled and the insights derived from this analysis, this research aims to serve as a valuable resource for the legged robotics community, guiding researchers and practitioners in the selection and implementation of control strategies. The ultimate goal is to contribute to the advancement of legged robot capabilities and facilitate their successful deployment in real-world applications. In this study, we employ the Unitree Go1 quadrupedal robot as a testbed, subjecting it to a variety of conditions including different terrains and external perturbations to assess the performance of MPC and RL controllers. Our findings reveal that RL exhibits superior force rejection in scenarios involving external forces, albeit relying heavily on torque in a single joint, while MPC provides a balanced torque distribution across all joints. In stumbling scenarios, MPC outperforms RL in recovery time, although both controllers face challenges when the robot falls into a failure state. Furthermore, the generalization capabilities of RL are evaluated across different terrains, demonstrating a performance drop in slippery conditions and uneven terrains compared to flat frictional surfaces. The temporal demands of RL, encompassing optimization and training phases, are contrasted with the real-time operation and parameter flexibility of MPC

    Now a day’s Obesity/ Sthoulya is a burning issue, but it is not being easy to burn it. Abdominal obesity also known as central obesity. With all kinds of foods becoming readily available at any times while humans are sedentary, intake of higher energy and less energy expenditure. Ayurveda describes Medopachaya as Sthoulya, it is a Santarpanajanya vyadhi said as one among Asthanindita purusha.According to the WHO, obesity is one of the most common, yet among the most neglected, public health problems in both developed and developing countries. Globally 1 in 6 adults is obese and nearly 2.8 million individuals die each year due to overweight or obesity. India is just behind US and China in this global hazard list of top 10 countries with highest number of obese people.The diuretic and purgatives drugs are also used to treat obesity, but the action is for shorter term and the patients again put on weight after cessation of treatment. In Ayurveda we offer several treatment measures to treat obesity. Here is an attempt made with safety management using principles of Panchakarma. 30 Patients were equally divided in 2 groups and treated Udvartana with Kolakulatthadi churna and Tummy trimmer by Sauna shaping belt, their comparative effects in central obesity. On the other hand corporate sectors are selling commercial slimming belts and are being sold out like hotcakes. Comparing both the procedures, Udvartana has given better result than Tummy trimmer

    Today, Cloud computing is a buzz word in IT industry. Cloud, a shared pool of computing resources, allows access to needed resources on demand through internet and web applications. Since data is outsourced to third party, user needs to maintain the accountability of their data in cloud. Hence preserving the confidentiality and securing the sensitive data in cloud is a major concern. Many cryptographic techniques have been proposed by researchers to assure the confidentiality of the user2019;s data in cloud. But, the challenging task is to provide the secure search over this preserved data which has been encrypted so as to retrieve the effective data. Hence, we are proposing a system to have a secure search over the encrypted data on the cloud which preserves its confidentiality. In our system, a noble approach has been made using the Commutative-RSA algorithm, a cryptographic technique where the dual encryption takes place thus reducing the overall computation overhead. The search operation over the encrypted data is based on the tree search algorithm which supports multi-keyword search. Based on the relevance score, the more appropriate data is retrieved on the search operation. Using this approach, the information is not leaked when the encrypted data is searched by users and also the queries are handled in an efficient way. Finally, we demonstrate the effectiveness and efficiency of the proposed schemes through extensive experimental evaluation

    Gridhrasi as mentioned in Ayurveda explains a disorder where in pain starts from Sphik pradesha and radiates downwards to Kati, Prusta, Uru, Janu, Jangha and Pada, Due to this, the patient is unable to walk properly. Gridhrasi can be compared with Sciatica. Sciatica is a relatively common condition with a life time incidence varying from 13% to 40%. The corresponding annual incidence of an episode of Sciatica ranges from 1 to 5%. The incidence of Sciatica is related to age. It is rarely seen before the age of 20. Incidence peaks in fifth decade declines thereafter.Snehana and Swedana are considered as a general line of treatment for Vata Vyadhi which can be taken as a line of treatment for Gridhrasi also. Patra pinda Sweda (Vatashamak) and Nadi sweda (Vata Kapha shamak) is one such treatment modality comes under Snehana and Swedana is known for relieving the symptoms. Murchita Tila Taila due to its Vata Shamaka has been taken for the Sthanik abhyanga.30 patients of Gridhrasi were randomly selected and divided into 2 groups. Group A: 15 patients received Patra pinda sweda and Group B: 15 patients received Nadi sweda up to Samyak Swinna lakshana. Overall assessment of both groups, out of 30 patients, 2 (6.67%) got complete remission, 13 (43.34%) patients got marked response, 6 (20%) patients got moderate response and 9 patients got mild response

    Content placement algorithm is an integral part of the cloud-based content de-livery network. They are responsible for selecting a precise content to be re-posited over the surrogate servers distributed over a geographical region. Although various works are being already carried out in this sector, there are loopholes connected to most of the work, which doesn't have much disclosure. It is already known that quality of service, quality of experience, and the cost is always an essential objective targeting to be improved in existing work. Still, there are various other aspects and underlying reasons which are equally important from the design aspect. Therefore, this paper contributes towards reviewing the existing approaches of content placement algorithm over cloud-based content delivery network targeting to explore open-end re-search issues

    Effect of Bindu Ghrita on external application over Nabhi in Vibandha w.r.t. Constipation - A Case Series

    Vibandha as both the terminologies have similar features like Purish Nigraha (obstruction of stool), Pakvashaya Shoola (pain abdomen), Parikartika (pain during defecation) etc. Constipation can occur at any age and is more common among individuals who resist the urge to move their bowels at their body's signal. Body is originally composed of Dosas, Dhatus and Malas. In Ayurveda there are so many preparations and Karmas to treat the constipation. By the application of Bindu Ghrita on Nabhi by penetrating into skin it enters Pakwashaya through Srotas due to Virya of the drug it expels the Dosha through Adhobhagahara and it expels Mala only in two external applications over Nabhi. By application over Nabhi expel the Dosha through Pakwashaya and relives the Vibandha
