  An electrical measurement is non-linear when it is affected by the applied stimulus, i.e. when the measured phenomenon changes with amplitude. If pinched hysteresis loops can be observed in the voltage current representation, the underlying tissue can be classified as a memristor. Several biological memristors have been published, like human skin and apples. However, changes in the polarization impedance of electrodes may also cause pinched hysteresis loops. The question whether the reported biological memristors are real or whether the results just reflect changes in the polarization impedance arises. If the impedance of the measured object is close to or smaller than the polarization impedance of the used electrodes, the latter may dominate the measurement. In this study, we investigated the non-linear electrical properties of silver/silver chloride electrodes in a sodium chloride solution that has a similar concentration as human sweat and compared these to results from human skin. First of all, we found that silver/silver chloride electrodes in sodium chloride solution can be classified as memristors. However, the currents obtained from the sodium chloride solution are much higher than the currents recorded from human skin and there is a qualitative difference in the pinched hysteresis loops in both cases. We can conclude that the non-linear electrical measurements with silver/silver chloride on human skin are actually dominated by the skin and we can confirm that the human skin memristor really exists.

  This paper presents a system to tangibly manipulate the virtual patching cords in graphical programming environments, such as Max and Pure Data. The system includes a physical interface, a communication protocol, and a software library, providing physical extension of the graphical programming paradigm. The interface includes a patch bay with connectors representing signal inlet and outlets from the programming environment. When inlets and outlets are connected with patching cords, equivalent virtual connections are created at runtime. The system supports one-to-many and many-to-one connections with different signal combination schemes. The design of the hardware and software components of the current prototype is detailed in the paper, as well as possible use of the system for programming and live performances.

  This thesis designs a Gaussian pulse generator by the method of up-conversion with for use as a front end transmitter unit of an UWB-IR. The baseband pulse is generated using the delay elements (CTBV technique) but having the carrier frequency sourced externally can offer the advantage such as higher tunability of the pulse shape and mitigate phase noise if the clock source is jitter-free. The architecture design is successful and the simulation results exhibit the expected rendering of the up-converted Gaussian pulse trajectory. The design is implemented in the 65nm CMOS process technology by TSMC. The thesis briefly describes the basic radar fundamentals that are influenced as part of the pulse tuning capability, such as the carrier frequency, bandwidth which affects the resolutions and penetration into lossy mediums of the target. The potential applications of the system are also described, such as in snow hydrology, biomedical applications, etc. The architecture is described with reasoning for taking a specific design approach, providing the necessary component dimensions that can help replicate the design by other interested users. The chip has arrived on at the facility on 7 June 2020, one week before the deadline for submission of this thesis dated 15 June 2020. Within this one week window period, the wire-bonding of the chip on the PCB, setting up of the types of equipment required for measurement has been conducted and attempt to get the successful results have been made, but no expected results have been obtained from the implemented chip. Due to the shortage of time, further investigation of the problems or re-analyzing the design for potential faults could not be made.
