Additionally, the increase of systems that are deployed on hardware requires security to be embedded in small area to protect intellectual property, hardware, and integrity and confidentially of sensible data. Therefore, in this work a design and FPGA implementation of a highly resource-efficient AES-256 encryption and decryption engine is presented, as well as its comparison with state-of-the-art designs. The design shows a reduction in the resources used due to its architecture to reuse hardware throughout all the processing. The design is implemented on a Xilinx Artix-7 FPGA.

Furthermore, a light source and a polarizer are integrated in the measurement setup which is configured using an QT application.

Based on the measurement of the time interval, distance can be calculated by applying the equation of motion. In application, achieving an exact distance measurement is quite strenuous because the operating conditions of the design are susceptible to change due to environmental factors. Therefore, to achieve accuracy in distance measurement, the time interval between the emission and reception of light must be measured precisely. For this purpose, a delay asymmetry compensation logic is developed. This thesis elaborates the addition of debugging features, redesign of some components, digital calibration approach and the entire testbench environment of the delay asymmetry compensation logic. It also sheds light on the implementation of the designed logic for its successful realisation in real hardware. Lastly, it concludes by narrating future prospects and further scopes of development.

A sophisticated CAE workflow is used to calculate the operational characteristics of 50 machine designs with 50 impeller geometry variations each. A Kriging-based surrogate model is trained to approximate the efficiency of any machine designs' best geometry design. The models are implemented into a machine design workflow. As a result, duty-specific Cordier lines are introduced. They are automatically generated for a set of machine design parameters. The efficiency of the designs along the duty-specific Cordier lines is approximated. Using optimization techniques, an optimal compressor design for the given duty on every specific Cordier line may be identified. This highly increases the amount of information available in the early design stages for radial turbocompressors.
