Characteristics of small signal components for circuit designers are very important in circuit design. Many researchers have been working hard on removing the unwanted parasitic effects which is used to get the intrinsic characteristics of the small signal parameters. In this thesis, we propose a novel four-port de-embedding procedure which based on two-port cascade structure de-embedding procedure and combined with metal and polysilicon ground-shielded technology, and let four terminals of MOSFET are connected individually to four signal pads. With such de-embedding procedure, the intrinsic and substrate element values of small-signal model are extracted by different bias.

Recent advancements in semiconductor fabrication technology have enabled field-programmable gate arrays (FPGAs) with hundreds of embedded memories. Usually, these embedded memories can be configured to work with different widths of address and data buses, In some FPGAs there is also a variety of different types of embedded memories with different capacities and configuration sets. As a consequence, it is becoming cumbersome to bind the data memory of an algorithm to these embedded memories manually. A computer-aided design tool that automates the process of binding embedded memories can save the engineering time for a design, as well as explore different alternatives to bind the data memory with the use of less embedded memories and less amount of peripheral hardware in terms of logic cells of the FPGA. In this thesis, we first motivate the need for an algorithmic solution to the memory binding problem in FPGAs and explain the design trade-offs. Then we present an exact solution for the problem using a branching method to search the solution space exhaustively. However, due to the large solution space and the plenitude of choices in each step of the algorithm, the runtime of the algorithm is far from being acceptable for realistic problems. To manage the runtime, we have developed a fast heuristic approach. Our experimental results show that the heuristic method can achieve a suboptimal solution, which for the small problem instances is shown to be close to the optimal in acceptable runtime. Moreover, when compared to manual solutions, besides substantially improving the implementation time, the heuristic can often enable a more efficient usage of the FPGA logic resources and embedded memories. / Thesis / Master of Applied Science (MASc)

The OFDM technology has been extensively used in many radio communicationtechnologies. For example, OFDM is the core technology applied in WiFi, WiMAXand LTE. Its main advantages include high bandwidth utilization, strong noise im-munity and the capability to resist frequency selective fading. However, OFDMtechnology is not only applied in the field of radio communication, but has alsobeen developed greatly in acoustic communication, namely the so called acousticOFDM. Thanks to the acoustic OFDM technology, the information can be em-bedded in audio and then transmitted so that the receiver can obtain the requiredinformation through certain demodulation mechanisms without severely affectingthe audio quality.This thesis mainly discusses how to embed and transmit information in audioby making use of acoustic OFDM. Based on the theoretical systematic structure, italso designs a simulation system and a measurement system respectively. In thesetwo systems, channel coding, manners of modulation and demodulation, timingsynchronization and parameters of the functional components are configured in themost reasonable way in order to achieve relatively strong stability and robustnessof the system. Moreover, power control and the compatibility between audio andOFDM signals are also explained and analyzed in this thesis.Based on the experimental results, the author analyzes the performance of thesystem and the factors that affect the performance of the system, such as the typeof audio, distance between transmitter and receiver, audio output level and so on.According to this analysis, it is proved that the simulation system can work steadilyin any audio of wav format and transmit information correctly. However, dueto the hardware limitations of the receiver and sender devices, the measurementsystem is unstable to a certain degree. Finally, this thesis draws conclusions of theresearch results and points out unsolved problems in the experiments. Eventually,some expectations for this research orientation are stated and relevant suggestionsare proposed.

This thesis is a study in the change of the use of audiovisual elements between the 1991 Gulf War news coverage and the 2003 Iraq War news coverage. The purpose of this study was to analyze audiovisual elements in war coverage from the 1991 Gulf War and the 2003 Iraq War in order to better understand critics' complaints that the news coverage of the 2003 Iraq War was sensationalized through the use of techniques more commonly associated with the entertainment industry. Specifically, this paper examines the use of descriptions, parasocial relationships, sound effects, music, and superimposed graphics to understand how war coverage has changed between the two wars. The results indicate that portions of the substantive content of the news coverage have been replaced with superficial content.

Simulating virtual objects which can deform or break apart within their environments is now common in state-of-the-art virtual simulations such as video games or surgery simulations. Real-time performance requires a physical model which provides an approximation to the true solution for fast computations but at the same time provides enough believability of the simulation to the user. Recent research in object deformation and fracture has revolved around embedding portions of the simulation for graphical display inside a much simpler physical domain which is invisible to the user. Embedding complex geometry in a simpler domain allows for very complex effects to occur in a much more robust and computationally efficient manner. This thesis explores a novel method to efficiently embed a high-resolution surface mesh inside a coarse tetrahedral physical mesh for the purposes of interactive simulation and display. A technique to display interior regions as solid geometry without explicitly re-meshing the graphical mesh during fracture has been explored and developed. Keeping the graphical mesh static in memory during simulation allows the geometry to be off-loaded to the GPU while shaders can be utilized to only display portions of the geometry which are locally contained within the physical mesh. Recent advances in GPU technology have also been exploited in order to provide an increase in visual fidelity and help achieve the illusion that the virtual object itself is breaking apart in a physically plausible manner.

My degree project aims to create a set of furniture and space which all “warped” by the voices of my beloved family member. I investigated how to record and translate the voices and materialize them into furniture. I processed the emotion of missing my family by materializing their voices through my “voice embedding methods.” Which I translate voices into form.  My “warped” space aims to reflect the power of human emotions. The voice curves that I extract from the “voice warping method” are rich in information and emotions. I want this “warping complexity” to question the ideology of the clean and empty “ideal space,” which is the tendency in today’s interior architecture and furniture design.

Internet of Things, or the infrastructure of the information age society, is an expanding area of research. It is the idea that physical things that we have today, can be turned into devices by being connected to a network. The purpose of these devices is through more sensors and actuators, allow smarter and more robust infrastructure to be built, as well as improving consumer devices interoperability. This thesis will investigate the current state of the art application layer communication protocols that have been developed with resource constrained mobile devices in mind. It will look specifically at high latency mid-range wireless cellular communication by investigating how the protocols affect energy consumption for an embedded Internet of Things device. This is done with the constraint that these findings needs to be applicable to the fifth generation of cellular networks, as well as extensions to current generation standards. The application layer communication protocols Constrained Applications Protocol(CoAP), Message Queue Telemetry Transport(MQTT) and Hypertext Transfer Protocol(HTTP) used on multiple modem modules, are investigated in a quantitative approach in deductive survey experiments, testing a variety of what is concluded to be typical sensor and actuator scenarios. The goal with the survey, is to ultimately select the protocol that shows to be the most suitable for a project to build a prototype platform for embedded mobile devices in the shape of publicly shared bikes in a city. This prototype is described and its architecture and design decisions are presented and argued for. The survey discovers that CoAP is the most suitable protocol for the purpose of the thesis, and proceeds to show how it is applied to the described platform.
