Design And Analysis Of a Lift Assist Walker
ABSTRACT
Walkers provided stability to the elderly but cannot assist a person from sitting to standing. The objective of this project is to present the design and analysis of a lift assist walker. This report discusses the design and analysis of a collapsible lift assist walker Continue reading
Multicore, Multithreaded, Phase-synchronous Fm Sound Synthesizer
ABSTRACT
This project implements a phase-synchronous FM synthesis algorithm in hardware. Envelope and low frequency oscillator modulation of oscillator parameters is implemented. The microcontroller the system is based on, the XMOS XS1-G4, allows for Continue reading
Digital Guitar Effects Unit and Amplifier
ABSTRACT
This report outlines the design and implementation of a digital guitar effects unit and amplifier. The main portion of this project consisted of the digital equalizer and effects. Several commercial equalizers were researched in order to decide the typical Continue reading
Evaluation of Software Using the Finite Element Method by Simulating Transformers and Inductors
In this bachelor thesis several software, capable of calculating and simulating complex problems concerning the power losses in inductors and transformers with the finite element method, have been evaluated and used to solve test cases provided by Continue reading
Expanding Operation Ranges Using Active Flow Control in Francis Turbines
