A HYBRID NONLINEAR VIBRATION ENERGY HARVESTER FOR REMOTE SENSING APPLICATIONS
(Mechanical Engineering, 2023 , Master Thesis)
Energy harvesting mechanisms can be used to extract energy from ambient surroundings to power small electronic devices which has a significant advantage in realizing self-sustaining wireless devices. The piezoelectric ...
DEVELOPMENT AND EVALUATION OF A WIRELESS ACTIVE NOISE CONTROL SYSTEM IN AN ENCLOSED ENVIRONMENT
(Mechanical Engineering, 2023 , Master Thesis)
Active noise control (ANC) is a method used to reduce acoustical vibrations mainly within the low-frequency range. This thesis aims to implement a wireless active noise control system in an enclosed environment, evaluate ...
THERMAL COMFORT CONDITIONS OF AN INDOOR SWIMMING POOL
(Mechanical Engineering, 2023 , Master Thesis)
In this thesis, the thermal comfort and indoor conditions for an indoor swimming pool located in desert climate are investigated numerically. Such climate is characterized by very mild winters, and very hot and sunny summers ...
SUPPLY CHAIN MODELING OF ADDITIVELY MANUFACTURED VERSUS CNC-PRODUCED SPARE PARTS
(Mechanical Engineering, 2023 , Master Thesis)
This research proposes a generic BLOC-ICE-based framework that considers multiple aspects of the adoption of additive manufacturing (AM) in the spare part supply chain. It proposes also a multi-period multiple parts ...
MECHANICAL RESPONSE OF APPLYING DIFFERENT PARAMETERS ON NEGATIVE STIFFNESS HONEYCOMB STRUCTURE
(Mechanical Engineering, 2023 , Master Thesis)
It has become apparent that negative stiffness behavior may have potential applications in vibration isolation mechanisms, vibro-acoustic dampening materials, and mechanical switches. Unlike traditional honeycombs, due to ...
INVESTIGATING FATIGUE LIFE IN BOLTED FLANGE CONNECTION IN WIND TURBINE TOWERS
(Mechanical Engineering, 2023 , Master Thesis)
A comprehensive assessment of fatigue was performed on an L-flanged bolted connection under four different wind speeds. The wind turbines were subjected to average wind speeds of 5, 10, 15, and 20 m/s. The primary objective ...
TOWARDS AN EFFICIENT HEALTH CONDITION MONITORING STRATEGY APPLIED FOR GEARING MECHANICAL SYSTEMS
(Mechanical Engineering, 2023 , Master Thesis)
Cracked teeth are a common phenomenon for gears. The dynamic behavior of gears in the presence of cracks and poor lubrication conditions that lead to rubbing between teeth are not well understood, which limits the development ...
Design, Development, and Testing of Torque and Angle Measurement System for a Traction Machine
(Mechanical & Industrial Engineering, 2023 , Master Thesis)
This thesis presents the development of a traction measuring system designed to evaluate the interaction between shoes and playing surfaces to prevent lower extremity injuries. The interaction between shoes and playing ...
Integrated Machine Learning Approaches for Comprehensive Bearing Health Monitoring and Fault Classification Using Multi-Sensory Data
(Mechanical Engineering, 2024 , Master Thesis)
Modern industries heavily rely on machines equipped with rolling-element (RE) bearings. However, these machines face substantial risks due to potential bearing faults, where even minor defects can lead to catastrophic ...
NUMERICAL INVESTIGATION OF THE POTENTIAL OF USING HYDROGEN AS AN ALTERNATIVE FUEL FOR AN INDUSTRIAL BURNER
(Mechanical Engineering, 2024 , Master Thesis)
The impact of emissions resulting from burning many types of fuels is one of the biggest problems that affect the environment. Attention has recently been drawn to using some gases and mixing them with specific types of ...
