Laser Beam Optical Trapping Of A Nanoparticle, Rufaro Musvosvi

Posters, Presentations, and Papers

Optical trapping is the use of a laser beam, to trap small particles, similarly to using tweezers. A straight beam of light, focused correctly, can provide a force strong enough to control a nanoparticle. The objective of this project is to set up a Modular Optical Trapping Kit for the purposes of research and teaching. The project is split into two main parts. Part one is assembling the Trapping Kit, which includes building a Printed Circuit Board (PCB). Part two is measuring the necessary laser-force for different particles. This is an on-going project.

Understanding The Relationships Of User-Selected Music In Video Games, Memphis Wong

Liberal Arts and Engineering Studies

Music has been an integral part of video games in its contribution to users' gameplay experiences. Varying from simple sound effects to elaborate scores, music helps shape the reactive environment of each video game. In particular, video games that generate unique levels and scenarios based on music has become more popular as its own genre. Games such as Audiosurf take this further, with having the game revolve entirely around levels generated to custom tracks. The aim of this study is to analyze the impact of such games, when it allows a user to select his or her own music.

Gpu-Accelerated Lip-Tracking Library, Alex Deboui, Jesse Harder

Computer Science and Engineering Senior Theses

A major part of having correct pronunciation when learning a new language is moving your lips in the correct way. This is a difficult thing to learn and to teach. One solution to this is software which tracks a student's lip movements and provides feedback. This paper describes how we have created a C++ library to accurately track lips in provided images. Further, this library attempts to use a CUDA-enabled GPU implementation to improve the algorithm's performance. It will fall back on a CPU implementation if such a GPU is not found. As a result, the lip tracking library runs …

Fuzzy Xor Classes From Quantum Computing, Anderson Ávila, Murilo Schmalfuss, Renata Reiser, Vladik Kreinovich

Departmental Technical Reports (CS)

By making use of quantum parallelism, quantum processes provide parallel modelling for fuzzy connectives and the corresponding computations of quantum states can be simultaneously performed, based on the superposition of membership degrees of an element with respect to the different fuzzy sets. Such description and modelling is mainly focussed on representable fuzzy Xor connectives and their dual constructions. So, via quantum computing not only the interpretation based on traditional quantum circuit is considered, but also the notion of quantum process in the qGM model is applied, proving an evaluation of a corresponding simulation by considering graphical interfaces of the VPE-qGM …

Comparisons Of Measurement Results As Constraints On Accuracies Of Measuring Instruments: When Can We Determine The Accuracies From These Constraints?, Christian Servin, Vladik Kreinovich

Departmental Technical Reports (CS)

For a measuring instrument, a usual way to find the probability distribution of its measurement errors is to compare its results with the results of measuring the same quantity with a much more accurate instrument. But what if we are interested in estimating the measurement accuracy of a state-of-the-art measuring instrument, for which no more accurate instrument is possible? In this paper, we show that while in general, such estimation is not possible; however, can uniquely determine the corresponding probability distributions if we have several state-of-the-art measuring instruments, and for one of them, the corresponding probability distribution is symmetric.
