The ecology and human health are seriously endangered by air pollution. Due to the expensive expense of the monitoring equipment, Air quality surveillance hubs are sometimes restricted to few places. They give a sketchy representation of the city's air quality and ignore regional variances. Arrayed sensor networks can now be used to assess embracing timely environmental insights at numerous places...Show More

It is important to test all the functional modules of the space systems before it is being launched. The very stringent tests need to be conducted particularly for manned missions. The vibration is one of the most significant phenomena involved in testing of space systems. As the system faces periodic as well as random vibrations containing both high and low frequency components, testing its respo...Show More
Rheumatoid Arthritis (RA) is a persistent provocative ailment that effects and decimates the joints of wrist, finger, and feet. If left untreated, one can lose their ability to lead a normal life. RA is the most typical fiery joint inflammation, influencing around 1-2% of the total populace. Throughout the years, soft computing played an important part in helping ailment analysis in doctor's decis...Show More
Multi-modal robots exhibit poor performance in locomotion modes due to its additional weight when compared to a single modal robot. Furthermore, the kinematics of a multimodal robot is more complex due to the increased number of actuators hence more prone to errors and malfunctions. The aim of this study was to use topology optimization to reduce the weight of components in a multi-modal robot, op...Show More
Studies of spine mechanics have shown that the lumbar region experiences higher tensile and shear deformations compared to other regions which increase the probability of disc injury. Hence, studies on lumbar spine mechanics are vital to understand failure of vertebrae and related mechanics. This research paper focuses on spine mechanics of L3-L4 lumbar using Computer Aided Design (CAD) and Finite...Show More
PID controller is one of the most robust and well-implemented controller in today's industry. However, the advancement of technology has urged the industry to improve overall process in term of its overshoot, rise time, settling and other domains. In this paper, Particle Swarm Optimization (PSO) algorithm is implemented to optimize the controller parameters in order to improve the system performan...Show More
Representation learning is the central role for all natural language processing task. Bag of Words method lacks in semantics and word order, hence word embedding model Word2Vec is used to capture the word semantics. But for morphological rich language, the vector representation would be noisy due to polysemy. To address these problems, Bag of Concepts is introduced to capture association between t...Show More
This paper proposes a study of a PID Controller design for a Magnetic levitation system. The system is composed of an electromagnet (coil), an infrared sensor used to measure the levitated object's position and a controller. The PID continuously adjusts its output based on the information provided by the sensor, thus modifying the electromagnetic field intensity influencing on the ball's position....Show More
Three-Phase Separators are used to separate well crudes into three portions; water, oil, and gas. A suitable control system should be in place to ensure the optimum function of the Three-Phase Separator. The current PID tuning technique does not provide an optimum system response of the separator. Overshoot response, offset, steady-state error and system instability are some of the problems faced....Show More
This research paper presents the study on design of arm exoskeleton for stroke rehabilitation purpose. The mechanical design of the exoskeleton focuses on few aspects of the arm exoskeleton which are length and the design of the exoskeleton and motor specification. Besides, the experiment of obtaining surface electromyography (sEMG) signal for repetition training for physiotherapy patient purpose ...Show More
Walking aids are extensively used by elderly individuals to improve their stability and ambulatory ability. Knowledge of biomechanical and functional requirements for the effective use of walker is still limited as per the current data available. In this paper, an instrumented walker is discussed theoretically and a new system is developed using the measurement of subject's resultant arm upper ext...Show More
Electromyography (EMG) based control is growing to be a part and parcel of the assistive devices technique today. Nonetheless, high sensitivity of EMG to the muscular fatigue affect the performance of EMG signal as a control input to the assistive devices. In this paper, the influences of muscular fatigue on the ankle joint motion recognition have been investigated. Three shank muscles and two ank...Show More
The lumbar region is highly susceptible to disc degeneration due to it supporting body weight and loads from daily activities. Disc degeneration itself is a complex subject and understanding the biomechanics of the condition is integral in providing corrective treatments for those affected. Measurement of Range of Motion (RoM) and loads acting on lumbar spine are essential in studying the effects ...Show More
Degenerative Disc Disease is a condition which is both asymptomatic and causes various complications to the spine if not treated including low back pain.
