Convergence rates of iterative algorithms for solving non-linear fixed-point (or root-finding) problems depend on the quality of the solution guess done in each iteration, which is used as the starting value in the next step. To avoid instabilities and oscillations, that guess is u...

The correct use of Child Restraint System (CRS) is an internationally recognized effective measure to protect the safety of child occupants, which can reduce the probability of children's road traffic accident death by 54%-80%. Finite element (FE) study is one of the important ...

The study investigates a specific issue in the Czech prison system: the conflict between prison employment and therapeutic/counselling programmes offered. Drawing on 55 semi-structured interviews with specialized prison personnel from 10 Czech prisons, I argue that prison employment is disproport...

Different measuring techniques have been used to objectify the classification of hoof shape. The MicroScribe is a novel tool that might prove useful for measuring hooves without prior reconstruction or compensation of projection artefacts. The aim of this study was to compare biometric&...

The evaluation of strike impact is important for optimal training, conditioning and tactical use. Therefore, the aim of this study was to evaluate ground and pound strikes, in terms of net force variability, across genders and performance levels. Eighty-one participants, professional men...

Considering occupants’ safety in highly automated vehicles (HAVs) is one of the future trends in mobility. Passengers will not deal with driving the car anymore, as a result of the automated driving system (ADS) application. Seat backs can be reclined by occupants during long ...

Objective: The future mobility challenges leads to considering new safety systems to protect vehicle passengers in non-standard and complex seating configurations. The objective of this study is to assess the performance of a brand new safety system called nanobag and to compare it ...

Virtual human body models contribute to designing safe and user-friendly products through virtual prototyping. Anthropometric biomechanical models address different physiques using average dimensions. In designing, e.g., personal protective equipment, orthopedic tools, or vehicle safety systems, biomechanical models...

Musculoskeletal research questions regarding the prevention or rehabilitation of the hand can be addressed using inverse dynamics simulations when experiments are not possible. To date, no complete human hand model implemented in a holistic human body model has been fully developed. The ...

For a long journey, the occupants of highly autonomous vehicles (HAV), with non-standard seating, can communicate easier. The question is… Are non-standard seating configurations as safe as standard seating in a frontal crash? The Virthuman model is used to answer this question. It ...

In finite element calculations, the integral forms are usually evaluated using nested loops over elements, and over quadrature points. Many such forms (e.g. linear or multi-linear) can be expressed in a compact way, without the explicit loops, using a single tensor contraction expressio...

Current industrial trends bring new challenges in energy absorbing systems. Polymer materials as the traditional packaging materials seem to be promising due to their low weight, structure, and production price. Based on the review, the linear low-density polyethylene (LLDPE) material was id...

Several studies have assessed birth-related deformations of the levator ani muscle (LAM) and perineum on models that depicted these elements in isolation. The main aim of this study was to develop a complex female pelvic floor computational model using the finite element method to&...

Musculoskeletal models of the shoulder complex yield the possibility to aid in clinically relevant research questions e.g. tears of the supraspinatus and the resulting mechanical impact during abduction of the humerus. One of the major contributors to this motion is the deltoid muscle&#...

Objective of this study was to develop an MRI-based finite element model and simulate a childbirth considering the fetal head position in a persistent occiput posterior position.

This paper presents the development of a new framework for stump–socket interface force estimation for future prosthesis optimization in transfemoral amputees. It combines experimental data and modelling, including gait analysis, subject-specific simulation of gait and finite element modelling of the&...

Based on electromyographic data and force measurements within the shoulder joint, there is an indication that muscle and resulting joint reaction forces keep increasing over an abduction angle of 90. In inverse dynamics models, no single parameter could be attributed to simulate this&#x...

The primary aim of this study was to assess the clinical feasibility of a policy where laparoscopic sacrocolpopexy (LSC) is the default procedure for the management of a significant apical pelvic organ prolapse (a-POP). As a secondary aim, we wanted to evaluate LSC outcomes in...

The goal was to evaluate the impact of BMI on the safety and efficacy of laparoscopic sacrocolpopexy in women with pelvic organ prolapse.
