Amplifier design for a piezoelectric transducer

Determining the speed of sound in curved bones

Current research on osteoporosis detection and transcranial imaging suggests that it is necessary to find a method to calculate the speed of sound in curved bones. A popular method to find the speed of sound in bones is by the bidirectional axial transmission technique. Currently, this method assumes that the arrival time of the head wave...

Stationary sets and on the existence of homeomorphisms between them: Stationaire verzamelingen en het bestaan van homeomorphismes tussen deze

Stationary sets are important tools in proofs of properties in sets of uncountable cardinality. In this thesis we look at mapping properties between stationary sets. First, the theory necessary for the construction and evaluation of stationary sets is made. That is the theory of ordinal, cardinal and regular cardinal numbers is build up from the...

Control Network of Bi-Directional Flyback DC/DC Converters

In this paper, the possibilities of a network of DC/DC flyback converters are explored. The implementation is as follows:<br/>Multiple microcontroller units are connected to a single board computer (ODROID C1+) via the I2C bus. Data collected by the MCU's is logged to an external server, where it is accessable via the internet. Users are able to...

Resource-constraint project scheduling with task preemption and setup times by Boolean satisfiability encoding and satisfiability (SAT) solver

Scheduling has been subject to much research. The resource-constrained project scheduling problem (RCPSP) is no exception. With the multiple different variations and additions to the standard definition that are possible, many exact, heuristic and meta-heuristic approaches have been proposed. One of those variations is allowing tasks in the...

The implementation of an MBAN gateway

Epilepsy is a severe neurological disorder that affects every aspect of a patient’s life. Unfortunately, there is no complete cure for everyone on the market yet. However, a lot of work has been done on seizure prevention. The entire project details the proof of concept implementation of a secure and reliable MBAN (Medical Body Area Network)...
