Momentum Of Particles From Time-Of-Flight Measurements, Joseph Best
Momentum Of Particles From Time-Of-Flight Measurements, Joseph Best
Senior Theses
In order to find the momentum of particles from time of flight measurements, I used a program called Geant4 to simulate experiments. I made a simple two detector setup, and I recreated a real world experiment. I spent a lot of time learning to code in C++ so I could use Geant4 correctly. I simulated these experiments shooting electrons, muons, and pions through the geometry and measured the time at two points in their flight. Subtracting the second time from the first gave me the time of flight distribution for each particle. I used ROOT to draw histograms of the …

Nd − Pdpa: N Dimensional Probability Density Profile Analysis, Arjang Fahim
Theses and Dissertations
Proteins are often referred as working molecule of a cell, performing many structural, functional and regulatory processes. Revealing the function of proteins still remains a challenging problem. Advancement in genomics sequence projects produces large protein sequence repository, but due to technical difficulty and cost related to structure determination, the number of identified protein structure is far behind. Novel structures identification are particularly important for a number of reasons: they generate models of similar proteins for comparison; identify evolutionary relationships; further contribute to our understanding of protein function and mechanism; and allow for the fold of other family members to be …
Brand Positioning Map And Analysis Using Web Scraping And Advertisement Analysis, Surya Bhatt
Brand Positioning Map And Analysis Using Web Scraping And Advertisement Analysis, Surya Bhatt
Theses and Dissertations
There’s a significant increase in online consumer forums. When customers set out to buy a product they use these forums to form an opinion. Our research focuses on comparing Brand positioning maps based on consumer reviews. We also analyse the impact of advertisements and expert reviews. Our goal is to show that combining consumer reviews with ads and electronic media will help us analyze the effectiveness of advertising on brand positioning maps. This approach shall also help us in making association graphs for a brand using words of perception/opinion associated with that brand/product. Which may in turn assist companies in …
Propagated Image Segmentation Using Edge-Weighted Centroidal Voronoi Tessellation Based Methods, Youjie Zhou
Propagated Image Segmentation Using Edge-Weighted Centroidal Voronoi Tessellation Based Methods, Youjie Zhou
Theses and Dissertations
Propagated image segmentation is the problem of utilizing the existing segmentation of an image for obtaining a new segmentation of, either a neighboring image in a sequence, or the same image but in different scales. We name these two cases as the inter-image propagation and the intra-image propagation respectively. The inter-image propagation is particularly important to material science, where efficient and accurate segmentation of a sequence of 2D serial-sectioned images of 3D material samples is an essential step to understand the underlying micro-structure and related physical properties. For natural images with objects in different scales, the intra-image propagation, where segmentations …
