In this paper, a new concept has been proposed to theoretically analyze the forces and torques on the upper body of a human riding on a two wheeler while facing a sudden halt/crash. This approach is applied to different joints by using a musculoskeletal model of the upper body. The optimal motion of the upper body during the sudden halt/crash is obtained by converting the multi degree of freedom control problem to a parameter based problem to study the nature and modes of response following a shock. A mathematical model with reduced degrees of freedom is proposed that retains the essential features of the motion most probable in the direction of the original velocity and the same (a non-linear formulation) is numerically investigated to find out the forces and torques on the thorasic trunk and the head-neck with the waist joint together with the displacements.

The finger is important for its function and appearance. Finger loss causes functional and mental health issues. Finger prostheses are frequently not very long-lasting. It must be changed on a regular basis because frequent insertion and removal could cause permanent damage or discoloration. There are numerous clinical and laboratory stages involved in the production of a new finger prosthesis, which takes time. Complex adjustments need to be made during the delivery visit even after the finger prosthesis has been made to ensure a secure fit and the right marginal adaptation.

The present paper considers the tribological principles on the maintenance of machinery whose three important areas are – Preventive, Condition Based and Proactive. Although breakdown is kept out of view, the morphology and analysis of failure provide important inputs for maintenance strategies. Condition based maintenance depends on three D’s – Detection, Diagnosis and Decision. In many machinery systems, the problem of predicting the remaining useful life – the Proactive part of the program, and evaluating the cost benefits are of enormous importance. Here the authors endeavor to highlight how the tribologist can significantly improve the maintenance practice

Robotic assistance has become essential for patients with motor dysfunction, and compared to passive training, robot-assisted training with subjective locomotion intentions promotes better health recovery. In this review, the authors briefly mention robot-assisted restoration of musculoskeletal health as a pressing new field in rehabilitation. Robotic application to restore musculoskeletal health can enhance rehabilitation, but must be used according to well-defined scientific protocols. The field of robotic therapy poses challenges for both technology and clinical practice.
