An intelligent robot called a "line follower" finds and follows a visible line that is embedded in the floor. The predetermined route can be seen as a black line on a white background with sharply contrasted colours. It can recognize the existence of an obstruction and select a different route to its destination. The robot that detects a line and tries to move in the direction of the target can be programmed to follow instructions. Different sensors can be used to detect the line. The robot can identify the path it needs to take using infrared sensors. The ultrasonic sensor is a device that can detect the obstacle by measuring the distance using sound waves and avoiding collision.

This paper presents a new monitoring tool and event management method for data centre compute, network and storage infrastructure based on node event processing. The uptime of highly classified data centres are not only to be maintained at the highest level of reliability and availability of the operation, but also fast, specific event identification and rectification, which altogether improves availability of the resources is important. The new method, using a tree node for each element of the data centre resources provides information about the compute, network and storage file system configuration in a specific node. Its major advantage is that in our case where a large number of heterogeneous computers are present, it helps us in monitoring all the elements of the computer resources and gives information for alerting the associated work centres before any of the identified events that might occur. By monitoring and informing apriori to the concerned work centres the state of the systems, it lowers errors in data centre physical infrastructure operating costs, improving at the same time the level of operations efficiency. This method resulted that the use of tree nodes significantly reduces the number of unexpected events, the time needed for the main event identification, and the maintenance response time to events. By using event entities processing, multilayer nodes have a significant impact on the efficient operation of data centre physical infrastructure. In this paper, the design and development of two customised dashboards to monitor the compute, storage and network elements of the heterogeneous data centre for uptime maintenance and optimal performance is presented. The dashboards are designed, keeping in view the nature of tasks carried out and the resource requirements of various work centres in the data centre. One dashboard displays dynamically created icons for each of the compute resources in the data centre. On clicking any of the icon, complete details of the corresponding server is fetched showing the status, usage, configuration and available resources. Furthermore, a unique colouring scheme is followed wherein the icon is displayed green if the server is healthy and orange if the server is facing a resource crunch (disk, memory, etc.) and red if the server is not reachable. The dashboard GUI refreshes every 5 min (is configurable), displaying the latest status details of the servers in the data centre. The second Dashboard is developed with the capability to monitor the storage, cloud and network infrastructure components. The dashboard collects data from different elements of the storage i.e. Meta Data Servers, Storage, Core and Edge switches etc. and processes the collected data to a customized format for display.

Many diseases, such as stroke, physical disability in the elderly, work injuries, and sports injuries can lead to weak limbs. Stroke is one of the main reasons for long-range disability, especially upper limb disability, that affects the activities of daily living (ADL) of individuals. Rehabilitation, such as manually assisted training or physical therapy that involves repeatedly moving the affected limb, is one of the most successful ways to reduce the effects of stroke. However, patients may be prevented from attending a clinic for rehabilitation for many different reasons, so researchers have developed robotic devices that can help in rehabilitation, enabling patients to perform repetitive movements at home with appropriate accuracy. These wearable robots (WR) must be smart, reliable, compatible, light, and functional for the safety of the user and must provide the appropriate support. This paper describes wearable devices, including rigid wearable devices and soft wearable devices, and some of their uses, especially in rehabilitation. It presents a summary of the designs used for the rehabilitation of the lower and upper limbs, especially the hand, which is the organ that is used most often in daily activities. The materials used in the manufacture of gloves that are used to rehabilitate the hand must be taken into account, and the size and weight of the glove must be suitable so that the user can wear and remove it easily.

In the realm of mobile robotics, navigating around obstacles is a fundamental task, particularly in constantly changing situations. Although deep reinforcement learning (DRL) techniques exist that utilize the positional information of robot’s, environmental states, and input dataset for neural networks. Although, the positional information alone does not provide sufficient insights into the motion trends of obstacles. To solve this issue, this paper presents a dynamic obstacle mobility pattern approach for mobile robots (MRs) that rely on DRL. This method employs the positional details of dynamic obstacles dependent upon time for establishing a movement trend vector. This vector, in conjunction with another mobility state attribute, forms the MR mobility guidance matrix, that essentially conveys the pattern variation of dynamic obstacles trend over a specified interval. Using this matrix, the robot can choose its avoidance action. Also, this methodology uses the DRL-based dynamic policy algorithm for the testing and validation of the proposed technique through Python programming. The experimental outcomes demonstrate that this technique substantially improves the safety of avoiding dynamic obstacles

The tremendous growth of digital data in cloud storage systems is a critical issue, as many duplicate data in storage systems cause extra load. Cloud Service Providers (CSPs) often employ Data Deduplication techniques to eliminate redundant data and store only one copy of data to save storage space and reduce transmission costs. Data Deduplication is mostly effective when multiple clients outsource the same data to cloud storage, but it raises security and ownership issues. This paper proposes a secure, Proof of Ownership (PoW)-based Data Deduplication scheme that has a low communication overhead and ensures that only valid cloud clients can download and decrypt ciphertext from cloud storage. The Advanced Encryption Standard (AES) is used as the encryption algorithm in the proposed scheme. It utilizes two modes of AES encryption, namely, Cipher Block Chaining (CBC) and Galois Counter Mode (GCM), with single-threading and multi-threading to upload and download ciphertext between the client and the server to measure the effect of upload and download times. We present a new approach for PoW to reduce communication overhead. PoW enables owners of the same data to prove to the cloud server that they own the data in a robust way. The comparison between CBC and GCM is implemented in a Java environment with two scenarios: single-threading and multi-threading. The simulation results show that AES-GCM with multi-threading is better during the uploading and downloading times

A numerical study has been carried out to determine the characteristics of fluid mixtures with different temperatures at 90° angles using ANSYS Fluent Computational Fluid Dynamics (CFD). The variation of the turbulence model used is k-ε, which is standard, RNG, and Realizable with the Near Wall Treatment method of Standard Wall Functions. The simulation domain is 90° angled with 2 perpendicular inputs and one output. The first step is to do a grid independence analysis with different mesh variations to get a proportional mesh. The research object is focused on section 6 with a distance of 35 cm before the flow output or located at 105 cm from the coordinate center. Validation was carried out by comparing temperature and velocity magnitude in research from S.N. Sridhara in section 6. It was found that the standard k-ε turbulence model was the best compared to the other variations. This gives a good idea of the distribution and flow behavior of the fluid which can be used for efficient elbow design.
