Rain erosion is a prominent issue in Offshore Wind Turbines (OWT) with wind farms experiencing heavy and frequent rainfall compared to onshore conditions. A simplified Springer model is used widely by industries to predict erosion initiation in composite materials and has been under various recent investigations to improve its predictability of rai...

There is an ever-present need to objectively measure and analyze sports motion for the determination of correct patterns of motion for skill execution. Developments in performance analysis technologies such as inertial measuring units (IMUs) have resulted in enormous data generation. However, these advances present challenges in analysis, interpret...

Human Activity Recognition (HAR) involves recognising and classifying human activities from data collected by sensors through machine learning (ML) techniques. The assessment of athletic movement via HAR has benefited sport performance analysis by identifying technical and tactical performance indicators. Hurling is a dynamic stick and ball inva...

Hurling is a stick-and-ball field game, predominantly played in Ireland. Knee injuries are frequent in Hurling and are associated with ongoing issues such as reinjury and decreased performance. Analysis of sport motion is crucial for understanding the quality of the technical aspects of sport skill, and to identify risk factors of injury. The...

The developments in the field of sports activity recognition and performance analysis research have been expedited by the advances in motion analysis technologies for data acquisition (Richter et al., 2021). During the time that these technologies were developed and inversely applied, there were coupled advancements in machine learning algorithms f...

The objective of this study was to systematically review the inertial measuring unit (IMU)-based methods employed in technique analysis research in team and individual swing sports, and to evaluate the supervised machine learning methods applied for activity detection and classification. A total of 13 study characteristic parameters were extracte...

Wormian (intrasutural) bones are small, irregular bones, that are found in the cranial sutures of the skull. The occurrence of Wormian bones in human skulls has been well documented but few studies have detected the presence of such bones in domestic animals. Although some research has linked the presence of Wormian bones to bone pathology, its ana...

This is the procedure carried out to etract beam-like specimens from the parietal bone of horse skull.

Intrasutural (Wormian) bone is well described in the medical literature but few studies have been done on domestic animals. This work aimed to determine the frequency of occurrence of intrasutural bone in the calvarium of the horse and, through bending tests, to determine if the presence of intrasutural bone altered the stiffness of the bone. Secti...

In this chapter, the complete development of an external intelligent knee prosthesis created by the Mechatronics Research Group (MRG) of the Simón Bolívar University is presented. This project has brought out several advances in the prosthetic field, especially referring external intelligent knee prostheses, such as bio-inspired shape of the chassi...

Bony enlargements are surgeries that have been performed for many years in people with shortening at their lower or upper limbs due to some kind of disease, which could be congenital or be acquired throughout their life. The problem with bone elongation lies in the recovery on both the time of the patient (which typically ranges from seven to eight...

There are a lot of people in the world who can`t perform their normal daily activities because they have physical disabilities, such as the loss of limbs. The population of Venezuela is not exempt from these difficulties which are caused mostly due to vehicle accidents. By 2001, the number of upper limbs amputees was approximately 32,758 people, ac...

Injuries of the vertebral column have gradually increased in recent years, this has favored interest in the production of computer models that provide medical solutions and guide in the diagnosis of certain pathologies. One of the challenges that can be found in the development of computational models is the simulation of the behavior of the interv...

The intervertebral disc is composed by three regions: an annulus fibrosus, a nucleus pulposus, and the terminal plates. The annulus fibrosus consist of concentric layers of collagen type I and II with fibers tilted in opposite direction in adjacent layers, the nucleus pulposus is composed of type II collagen and water. This work presents a sensitiv...

The intervertebral disc is the structure that lies between adjacent vertebrae in the spine; is composed by an annulus fibrosus and a nucleus pulposus, and work as a shock absorber. The annulus fibrosus consist of concentric layers of collagen type I and II, the nucleus pulposus is composed of type II collagen and water. In biomechanical studies of...

The increment in the use of cell phones and similar products in recent years has caused a growth of the number of young patients with neck pain, headache and shoulders pain, showing early degeneration of the cervical spine, particularly associated to a poor posture adopted when using the cell phone. The purpose of this paper is to propose a methodo...

En la actualidad es posible combinar programas para realizar diseños basados en estudios por elementos finitos que permiten realizar análisis de esfuerzos confiables, sin necesidad de exportar e importar información de un programa a otro. En el presente trabajo se optimiza el chasis de una prótesis inteligente de rodilla para pacientes con amputaci...

This paper presents a physiological model of a L4-L5 Functional Vertebral Unit (FVU) based on dimensions extracted from the literature, which is used as a platform for simulation of Nucleus pulposus prostheses prototypes. CAD computational tools and finite element simulations were used for stress analysis considering the anisotropy of the outer ann...

The human gait is one of the most important movements for the development of the human being life. It represents a sequence of synchronized movements of the joints and muscles activations of the lower limbs. The knowledge of how those movements are performed, taking into account the biomechanical foundations and the physiology of the elements invol...

Existen programas de reconstrucción ósea comerciales que si bien son muy eficientes en el proceso de segmentar imágenes, tienen carencias en los módulos de discretización; además son inasequibles para países en desarrollo. El objetivo de este trabajo es elaborar y comparar modelos de vértebras humanas creando una metodología de reconstrucción ósea,...

There is a very high demand for prosthetic components in developing countries, but this is far to be satisfied because such devices are imported and hence, not affordable by most people with disabilities; however, at the same time, many of these countries have professionals and technology to develop the products they need. This work presents an app...

The influence of the fixation plates on the ostheosynthesis process of the 41-C1 tibia fracture is analysed in this research, by studying the fracture fragments displacements when a compressive load is applied. A cadaveric tibia and a synthetic tibia were experimentally and numerically compared. Then, two different FEM of fractured tibia were devel...

The proximal tibia fracture 41-C1 is analyzed with and without the use of fixation plates. This analysis is done considering the different stages of the fracture healing callus (soft and mature). The study is built on a finite element model of a synthetic tibia (Synbone®), which assumes linear and isotropic material behavior. It was utilized to bui...
