Fast algorithm for joint unicast and multicast beamforming in large-scale systems
(2021-09-01)
We consider a joint unicast and multi-group multicast beamforming problem for massive multiple-input multiple-output (MIMO) system with a large number of unicast users. We propose an alternating direction method of multipliers ...
Triton: a domain specific language for cyber-physical systems
(2021-04-01)
The design of cyber-physical systems is non-trivial and often filled with tedious, error-prone tasks that could be represented in a better way. Engineers often work with low-level languages such as C and C++, with real-time ...
Analytical and experimental study of the effect of cutting tool microgeometry on the impact resistance of milling tools
(2021-01-01)
This thesis conducted a two-part investigation into the ability of a milling tool cutting insert to resist the impacts that occur during the milling process, with respect to the cutting edge microgeometry. The first part ...
Comparison of the force and torque transfer for different cam profiles
(2021-09-01)
This study presents static load and torque distribution measurements in groove cams for sinusoidal and cycloidal cam profiles. In this thesis, two different designs and apparatuses were developed and built for the static ...
