A POMDP framework for antenna selection and user scheduling in multi-user massive MIMO systems
(2022-04-01)
We use a partially observable Markov decision process (POMDP) framework to design a resource allocation policy for downlink transmit beamforming at a multi-antenna BS that is equipped with a massive number of antennas and ...
Design and development of a traction motor emulator using a three-phase bidirectional buck-boost AC-DC converter
(2022-04-01)
An industrial drive testing, with a ‘real-machine’ can pave way, for some serious issues to test-bench, motor, and the operator. A slight disturbance in control logic amid testing, can damage the physical machine or drive. ...
Modeling and experimental investigations of drilling carbon fiber reinforced composites
(2021-04-01)
The application of composites in different industries especially aerospace industry has significantly increased due to their phenomenal mechanical characteristics. Drilling woven composite parts is one of the most common ...
New approaches in training for in situ visualization of ionizing radiation measurements
(2022-08-01)
Surveying an environment for sources of ionizing radiation requires the use of measurement tools and skills developed from training in order to understand and analyze measurements. Recent advances in technology allow for ...
Analysis and mitigation of the impacts of integrating fast-charging stations on the voltage fluctuations
(2020-10-01)
As the number of electric vehicles increases, fast charging becomes a necessity in the electric service stations; not only to reduce the charging and waiting times for electric vehicles whether in service or in a queue, ...
Hot particle dosimetry using a wall-less tissue equivalent proportional counter
(2023-05-01)
Highly radioactive specks of irradiated nuclear fuel or activated material, colloquially known as 'hot particles', can enter the workplace or external environment from nuclear power plant operations such as refurbishment ...
A real-time 12-lead electrocardiogram remote patient monitoring and analytics framework
(2022-10-01)
This work presents XBeats: A machine learning-based framework for real-time electrocardiogram monitoring and analysis that uses edge computing and data analytics for early anomaly detection. The framework encompasses a ...
Robust multi-group multicast beamforming design and antenna selection for massive MIMO systems
(2023-04-01)
In this dissertation, we use an Alternating Direction Method of Multipliers (ADMM) algorithm to design robust multi-group multicast beamforming scheme for massive multiple-input multiple-output (MIMO) systems for two ...
Design of surface micro-machined inertial MEMS sensor with meta-heuristic topology optimization
(2023-03-01)
Micro-Electro-Mechanical Systems (MEMS) are getting popular for a variety of applications due to their small size, low cost, and good performance. MEMS devices are designed by combining simple shapes based on the experience ...
Development and assessment of integrated powering systems with alternative fuel choices for clean transportation
(2023-04-01)
This thesis presents novel engine systems using alternative fuels for aviation, rail, and marine transportation as follows: (i) alternative powering systems, such as fuel cells, on-board hydrogen production (ii) alternative ...
