Understanding the biomechanics of a normal and diseased knee joint is in urgent need for designing knee assistive devices and optimizing a rehabilitation exercise program. In this paper, we systematically searched

Impact of Different Developmental Instars on Locusta migratoria Jumping Performance. Appl. Bionics Biomech. (IF 1.141) Pub Date : 2020-03-26 Xiaojuan Mo,Donato Romano,Mario Milazzo,Giovanni Benelli,Wenjie Ge,Cesare Stefanini
Ontogenetic locomotion research focuses on the evolution of locomotion behavior in different developmental stages of a species. Unlike vertebrates, ontogenetic locomotion in invertebrates is poorly investigated. Locusts represent an outstanding biological model to study this issue. They are hemimetabolous insects and have similar aspects and behaviors in different instars. This research is aimed at

Numerical Investigation of Aerodynamic Noise Reduction of Nonpneumatic Tire Using Nonsmooth Riblet Surface Appl. Bionics Biomech. (IF 1.141) Pub Date : 2020-03-16 Haichao Zhou; Zhen Jiang; Jian Yang; Huihui Zhai; Guolin Wang
Unlike conventional pneumatic tires, the nonpneumatic tires (NPT) are explosion proof and simple to maintain and provide low rolling resistance. At high vehicle speeds, however, the complex airflow produced by the open flexible-spoke structure of NPT yields high aerodynamic noise, which contributes to sound pollution in the vehicular traffic environment. Inspired by the idea that a nonsmooth riblet

A Systematic Review of Real-Time Medical Simulations with Soft-Tissue Deformation: Computational Approaches, Interaction Devices, System Architectures, and Clinical Validations Appl. Bionics Biomech. (IF 1.141) Pub Date : 2020-02-20 Tan-Nhu Nguyen; Marie-Christine Ho Ba Tho; Tien-Tuan Dao
Simulating deformations of soft tissues is a complex engineering task, and it is even more difficult when facing the constraint between computation speed and system accuracy. However, literature lacks of a holistic review of all necessary aspects (computational approaches, interaction devices, system architectures, and clinical validations) for developing an effective system of soft-tissue simulations

Study on Behind Helmet Blunt Trauma Caused by High-Speed Bullet Appl. Bionics Biomech. (IF 1.141) Pub Date : 2020-02-19 Zhihua Cai; Xingyuan Huang; Yun Xia; Guibing Li; Zhuangqing Fan
The mechanism of Behind Helmet Blunt Trauma (BHBT) caused by a high-speed bullet is difficult to understand. At present, there is still a lack of corresponding parameters and test methods to evaluate this damage effectively. The purpose of the current study is therefore to investigate the response of the human skull and brain tissue under the loading of a bullet impacting a bullet-proof helmet, with

An Intelligent Gesture Classification Model for Domestic Wheelchair Navigation with Gesture Variance Compensation. Appl. Bionics Biomech. (IF 1.141) Pub Date : 2020-01-30 H M Ravindu T Bandara,K S Priyanayana,A G Buddhika P Jayasekara,D P Chandima,R A R C Gopura
Elderly and disabled population is rapidly increasing. It is important to uplift their living standards by improving the confidence towards daily activities. Navigation is an important task, most elderly and disabled people need assistance with. Replacing human assistance with an intelligent system which is capable of assisting human navigation via wheelchair systems is an effective solution. Hand
