In order to obtain haptic interaction with precise force feedback from the environment, for an exoskeleton, a robotic 2-jaw gripper is proposed. To reach this goal, a gripper is designed based on optimizing the link lengths to maximize the amount of weight that the gripper could hold and built withparallel jaws and two Force Sensitive Resistor (FSR) sensors for measuring the force applied on the jaws. the gripper is used as an end effector for a palletizing 3-DOF robotic arm and is interfaced to a computer using an Arduino board. the FSRs are both calibrated before object grasping, and as a result, the force exerted on each jaw while grasping objects is obtained. this data is consequently used to achieve four goals: detect an object presence, prevent the object from being damaged during grasp, evaluate the object weight through the coefficient of friction and obtain safe haptic feedback for a master exoskeleton (HEXON 1 ). the experimental results are provided within the mechanism relations and numerical simulation to validate the desired tasks.

this research offers a novel and complete technique to merge blockchain and big data, solving accuracy, security, and scalability issues. Five algorithms—integrating a decentralized storage solution, automating smart contracts, reaching an agreement (proof-of-work), sharding for scalability, and securely encrypting data for privacy—are advocated. the Decentralized Storage Solution Integration technique secures the system’s basis by building up a decentralized storage system, employing cryptographic hashing to ensure stability, and ensuring acceptance through proof-of-work. the technique uses sharding technologies for scaling, parallel processing, redundancy, and fault tolerance. the autonomous storage system and Smart Contract Automation algorithm automate compliance inspections. Clearer deals reduce transaction costs. this strategy is crucial for efficient, transparent, and cost-effective contractual negotiations. the agreement (proof-of-work) approach protects financial transactions with computer problem-solving. thus, the blockchain remains trustworthy, data is consistent, and interactions are visible. the proposed technique has been extensively investigated, and the findings reveal how each program is interconnected and vital to the system. Tables and figures indicate that the recommended strategy outperforms current combinations in all critical areas. the solution is essential because it is extensible, works with other systems, uses resources well, is easy to check, helpful, and cheap. Blockchain technology and big data are proposed as a better solution. It covers the essentials and ensures blockchain systems are secure, open, scalable, and privacy-protecting.

LDPC codes have been intensively used in various wireless communication applications, due to their increased BER performance. the present paper summarizes the state of the art applications of short length LDPC codes and proposes FPGA based application specific hardware architectures for short-length LDPC decoders. the decoding algorithms considered for implementation are both belief propagation and min-sum algorithm. Due to the increased BER performances, the proposed architecture make use of parallel computation capabilities offered by FPGA technology in order to implement the belief propagation algorithm. In spite of the iterative nature and increased computational complexity of the LDPC decoding algorithm, the proposed architecture achieves high-throughput, mandatory in real-time application and data transmission. the architecture for the LDPC belief propagation based decoder is based on arctangent hyperbolic function approximation used for check nodes update.
