Advancing Temporomandibular Joint Implant Design: Exploring the Impact of Functionally Graded Materials at the Site of the Prosthetic Joint

The mechanical failure of a temporomandibular joint (TMJ) replacement system can stem from various factors, with one notable cause being the unnatural kinematics and loading observed in prosthetic joint function. Given that,. the primary objective of the study was to investigate whether including functionally graded materials (FGMs) at the site...

How effective are minimax methods in mitigating sample selection bias?

Sample selection bias is a well-known problem in machine learning, where the source and target data distributions differ, leading to biased predictions and difficulties in generalization. This bias presents significant challenges for modern machine learning algorithms. To tackle this problem, researchers have focused on developing domain...

Model-specific Explainable Artificial Intelligence techniques: State-of-the-art, Advantages and Limitations

Artificial Intelligence (AI) and Machine learning (ML) applications are being widely used to solve different problems in different sectors. These applications have enabled the human-effort and involvement to be very low. The AI/ML systems<br/>make their own predictions and do not require a great deal of human help. However, over the last few...

Determining epitope specificity of T-cell receptors with Transformers

Transformers have dominated the field of natural language processing due to their competency in learning complex relationships within a sequence. Reusing a pre-trained transformer for a downstream task is known as Trans-fer learning. Transfer learning restricts the transformer to a fixed vocabulary; modification in transformer implementation...

Partial Least Squares on Hyperspectral data: A data-driven approach for predicting the growth of potato plants

The potato is a plant that can grow from another potato tuber. Farmers and producers have to contend with the declining quality of soil and are producing less vital potato tubers. The differences in emergence speed between batches of the same variety of potato tubers cannot be explained. This is why Project ‘Flight to Vitality’ (FtV) is...

Design of actively controlled semi- permeable trailing edge inserts for aeroacoustic noise reduction

An experimental study is conducted on the design of actively controlled semi-permeable inserts for mitigating turbulent boundary layer noise originating from the trailing edge of an airfoil. Two sets of perforated inserts with hole diameter: 0.8 mm and hole spacing: 1.5 mm &amp; 3 mm, are considered. The inserts are 3-D printed with a middle...

Happiness within Organizations: a process to aid in achieving a happiness mindset

Happiness is something we, as humans, seek to attain yet we are not entirely familiar with what exactly it means. Typology of fundamental needs (Desmet &amp; Fokkinga, 2020) explains comprehensively, yet detailed enough, the needs we must fulfil in order to be happy. An average person spends a third of their life at work (Pryce-Jones, 2010) and...

Multi-frame deep learning models for action detection in surveillance videos

Visual surveillance technologies are increasingly being used to monitor public spaces. These technologies process the recordings of surveillance cameras. Such recordings contain depictions of human actions such as "running", "waving", and "aggression". In the field of computer vision, automated detection of human actions in videos is known as...

Dynamic Stall Modeling for Wind Turbines

Modern wind turbines frequently operate at off-design conditions during their life cycle. They undergo dynamic loads characterized by unsteady aerodynamics. Predicting these unsteady aerodynamic loads has been very difficult due to the non-linear nature of unsteady aerodynamics. Especially when operating near the stall region, these turbine are...

Collision Avoidance for Predefined C-arm Trajectory using 3D Depth Measurements

Human-robot collaborative act is obvious nowadays in a modern intervention room. It is very important to ensure the safety of the patient along with other personnel in the operation theater and prevent damages to the equipment during an intervention. Due to the complex environment and multiple unknown dynamic objects in the room, vision-based...

Modelling of Modular Multilevel Converters for Fast and Accurate Simulation of Electromagnetic Transient Phenomena in HVDC Applications

Modular multilevel converters (MMC) are gradually becoming the technology of choice in high-voltage direct current (HVDC) power transmission for grid integration of large-scale offshore wind farms and multi-terminal HVDC transmission schemes. Each phase of an MMC HVDC terminal consists of several hundreds of identical submodules that switch a...

The Patching of Built Ornamental Heritage using Digital Fabrication

The purpose of this research is to explore the role of LIDAR Technology and Digital Fabrication techniques in the field of architectural conservation, particularly for the patching of ornamental heritage. The information is compiled in the form of a guide. Information gathered via the aid of experiments and subsequent observations is also...

Heart rate monitoring using PPG signals

This bachelor’s thesis discusses the idea and implementation of real-time heart rate monitoring using photo- plethysmography (PPG) signals. PPG signals measured from the wrist are often subjected to distortion and noise. Signal processing techniques that tackle these issues were investigated and implemented. The algo- rithm of choice was JOSS....

Antenna Beamforming for a 60 GHz Transceiver System

The main target of a 60 GHz transceiver system is to obtain data rates close to gigabits per second (Gbps) over short distances. The 60 GHz suffers from severe pathloss, inter-symbol interference (ISI) and a limited link budget. In order to improve the link budget, beamforming techniques are utilized. Antenna beamforming, i.e., combining signals...
