A review on application of finite element modelling in bone biomechanics

Abstract: Summary In the past few decades the finite element modelling has been developed as an effective tool for modelling and simulation of the biomedical engineering system. Finite element modelling (FEM) is a computational technique which can be used to solve the biomedical engineering problems based on the theories of continuum mechanics. This paper presents the state of art review on finite element modelling application in the four areas of bone biomechanics, i.e., analysis of stress and strain, determination of mechanical properties, fracture fixation design (implants), and fracture load prediction. The aim of this review is to provide a comprehensive detail about the development in the area of application of FEM in bone biomechanics during the last decades. It will help the researchers and the clinicians alike for the better treatment of patients and future development of new fixation designs.

A modified PID control with adaptive fuzzy controller applied to DC motor

Abstract: This paper represents a modified PID control using adaptive fuzzy controller A critique of performance of conventional PID and Adaptive fuzzy logic tuned PID controller applied to DC motor is provided A fuzzy logic controller (FLC) is evolved for tuning the three terms of PID controller automatically as per the fuzzy rules The adaptive FLC produces correction values for conventional PID controller, that are varying online with the system output The complete system consisting of adaptive fuzzy PID controller along with DC motor model is simulated using MATLAB/Simulink A comparison of conventional PID with adaptive fuzzy PID controller is demonstrated for reference speed tracking and load disturbance The results show that, the adaptive fuzzy tuned PID controller provides better dynamic behavior of DC motor with low rise time, low settling time, minimum overshoot and low steady-state error in speed and thus provides superior performance

Experimental Investigation of the Breast Phantom for Tumor Detection Using Ultra-Wide Band-MIMO Antenna Sensor (UMAS) Probe

Abstract: In this work, a novel Ultra-wideband-Multi-Input-Multi-Output Antenna Sensor (UMAS) probe is designed for the detection of the malignant cells in the breast. The Sensor probe has four radiating elements and it is operated within the 2.8 GHz to 20 GHz ultra-wide band range. Isolation between the radiating element is more than 20 dB. Further, three kinds of the breast phantoms (i.e. normal phantom, phantom with single and multiple tumors) are fabricated using tissue mimicking material. The electrical characteristics of the malignant cells are different from non-malignant cells of the breast. The S-parameter and Specific Absorption Rate (SAR) analysis are best approaches to detect the malignant cells in the breast. The UMAS sensing probe is embedded on the phantoms and S-parameters of the probe are recorded from the Vector Network Analyzer (VNA). Measured S-parameters of the probe for normal and malignant phantoms are differ from each other. The statistical machine learning concept of Principal Component Analysis (PCA) is also applied on the measured S-Parameters. Which exhibits clear detection of normal and malignant breast phantoms. Further verification is done by using Simulation based specific absorption rate (SAR) study of the phantom models for tumor detection. The obtained maximum SAR results are well differentiating the normal phantom.
