Efficient system reliability-based design optimization study for replaced hip prosthesis using new optimized anisotropic bone formulations
(
MDPI AG
, 2020 , Article)
An efficient reliability algorithm is developed to transfer the system reliability problem to a single-component reliability problem, considering the uncertainty of loading cases and the material properties. The main ...
An experimental and numerical investigation of the effects of the diaphragm pressure ratio and its position on a heated shock tube performance
(
Wiley-Blackwell
, 2022 , Article)
The main purpose of this work was to investigate the performance of heated shock tube (ST) with different pressure ratios and diaphragm positions numerically and experimentally. The numerical model was developed to simulate ...
Parametric Estimation from Empirical Data Using Particle Swarm Optimization Method for Different Magnetorheological Damper Models
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
The nonlinearity behaviour of magnetorheological fluid (MRF) can be described using a number of established models such as Bingham and Modified Bouc-Wen models. Since these models require the identification of model ...
Fractional-order controllers for stick-slip vibration mitigation in oil well drill-strings
(
SAGE
, 2021 , Article)
Drillstring–borehole interaction can produce severely damaging vibrations. An example is stick–slip vibration, which negatively affects drilling performance, tool integrity and completion time, and costs. Attempts to ...
Head Impact Severity Measures for Small Social Robots Thrown During Meltdown in Autism
(
springer link
, 2019 , Article)
Social robots have gained a lot of attention recently as they have been reported to be effective in supporting therapeutic services for children with autism. However, children with autism may exhibit a multitude of challenging ...
Longitudinal Studies of Wearables in Patients with Diabetes: Key Issues and Solutions
(
MDPI
, 2023 , Article)
Glucose monitoring is key to the management of diabetes mellitus to maintain optimal glucose control whilst avoiding hypoglycemia. Non-invasive continuous glucose monitoring techniques have evolved considerably to replace ...
An optimized CT-dense agent perfusion and micro-CT imaging protocol for chick embryo developmental stages.
(
BMC
, 2024 , Article)
Compared to classical techniques of morphological analysis, micro-CT (μ-CT) has become an effective approach allowing rapid screening of morphological changes. In the present work, we aimed to provide an optimized micro-CT ...
Broadband vibration energy harvesting from a non-deterministic system: Performance of different piezoelectric patch shapes
(
IOP Publishing Ltd
, 2021 , Article)
Harvesting energy from ambient structural vibration using piezoelectric materials gained massive interest in the past decade. Piezoelectric harvesters can be incorporated in many applications; however, one of the main ...
Enhancing the damping effect of MRF damper using an external magnetic excitation system
(
Institute of Physics Publishing
, 2023 , Article)
The magnetic field generated by the damper’s magnetic circuit governs the yield stress value of the Magnetroholgical Fluid (MRF) damper and hence its damping effect. This paper contributes to the literature on the development ...
Off-design performance analysis of combined CSP power and direct oxy-combustion supercritical carbon dioxide cycles
(
Elsevier
, 2021 , Article)
The solar power tower (SPT) has the potential to achieve high efficiency and large-scale power production due to its high achievable temperatures. However, thermal energy storage (TES) is required to solve the intermittency ...
