'Carlos Moutinho'] In civil engineering, the joints of structures are complex, and their damage is generally hard to be detected. Due to the insensitivity of structural modal information to local joint damage, this paper presents a method based on additional virtual mass for damage identification of a semi-rigid joint…

Preclinical evaluation of total knee arthroplasty (TKA) components is essential to understanding their mechanical behavior and developing strategies for improving joint stability. While preclinical testing of TKA components has been useful in quantifying their effectiveness, such testing can be criticized for lacking…

Purpose Precise preoperative planning is mandatory when a double-level osteotomy (DLO) is required to correct a severe knee deformity. Literature does not report a validated planning method regarding DLO that could be performed directly on digital radiographs using simple measurement tools. This study aims to validate…

Modern molecular mechanics force fields are widely used for modelling the dynamics and interactions of small organic molecules using libraries of transferable force field parameters. For molecules outside the training set, parameters may be missing or inaccurate, and in these cases, it may be preferable to derive…

An important application of haptic technology to digital product development is in virtual prototyping (VP), part of which deals with interactive planning, simulation, and verification of assemblyrelated activities, collectively called virtual assembly (VA). In spite of numerous research and development efforts over…

Total knee arthroplasty aims to relieve pain and restore function in the affected joint through artificial implants. Despite advances in design and surgical techniques, there are complications associated with surgery, especially concerning the patella. The use of musculoskeletal models in orthopedic surgery allows for…

Triarylboranes (BAr3) is one of the most important classes of Lewis acid catalyst. However, their molecular design still largely relies on the typical experimental trial-and-error strategy. Here, we introduced the virtual borane (VB) method—a novel computational approach for design of triarylborane catalysts—based on…

Skin Marker (SM) based motion capture is the most widespread technique used for motion analysis. Yet, the accuracy is often hindered by Soft Tissue Artifact (STA). This is a major issue in clinical gait analysis where kinematic results are used for decision-making. It also has a considerable influence on the results of…
