Automated Household Tracking System, James Triola
Automated Household Tracking System, James Triola
Honors Theses
The past few years have seen the highest recorded amount of waste produced in America. Despite several options of responsible wasting, landfills are still bearing the brunt of waste deposits. Although recycling is a common practice, it is still not accomplished with maximum efficiency, and composting is even less common in areas where it is not legally mandated. Food scraps and byproducts that could otherwise have been broken down in proper composting methods continue to pile up in landfills where they breakdown into methane gas. Although there is no easy answer to the complex problem that is consumer waste, the …
Classifying System Call Traces Using Anomalous Detection, William Doyle
Classifying System Call Traces Using Anomalous Detection, William Doyle
Honors Theses
We used data mining techniques to detect intrusions among system call traces and have outlined our results. Recent work at the intersection of security and machine learning has lead to better understanding of anomalous intrusion detection. There is a need to more thoroughly understand how anomaly detection can be used because of its potential applications and advantages over current standard methods. In this thesis, we report on a new approach of anomalous detection using system call traces. Our goal is to be able to create a system that can accurately detect hacking attacks by analyzing the sequences of system calls …
Comparing Stellar Populations Of Galaxies Across The Hubble Sequence: Reduction Of Pisces Near-Infrared Images, Vaishali Parkash
Comparing Stellar Populations Of Galaxies Across The Hubble Sequence: Reduction Of Pisces Near-Infrared Images, Vaishali Parkash
Honors Theses
To better understand the properties of high redshift galaxies and improve models of galaxy formation, we are investigating color radial profiles to study the stellar age, dust and metallicity distribution of galaxies of varying lumi-nosities and morphological types. Current data obtained in the optical and UV have shown that early-type galaxies have a flat color profile, or are bluer at larger radii, while late-type spirals are redder with increasing radius. These trends are believed to be linked with stellar population ages or dust. To break the age-dust degeneracy as well as to avoid the metallicity dependence, we have obtained near-infrared …
Pedagogical Tool For Usability Science Final Project Report, Daniel D. Mendelsohn
Pedagogical Tool For Usability Science Final Project Report, Daniel D. Mendelsohn
Honors Theses
A Sophomore Research Seminar (SRS) at Union College teaches about usability science, the study of designing interfaces that allow the user to accomplish a given task with less time and frustration. In this context, an interface can be anything that allows interaction with a physical or virtual device such as a web browser or the knobs on a stove. In this SRS, students design interface mockups, called prototypes, out of inexpensive material such as cardboard. Students use these prototypes to test their interfaces on real people, who are asked to perform a task that would be performed on a real …
R-Process Nucleosynthesis In Supernova Simulation, Lyda P. Urresta
R-Process Nucleosynthesis In Supernova Simulation, Lyda P. Urresta
Honors Theses
We examined a potential r-process site by modeling nucleosynthesis in a late-stage supernova explosion, considering different hydrodynamic conditions. After collecting the resultant abundances with respect to atomic and mass number, we decayed the isotopes in our data sample to stability. Then, we plotted the decayed and undecayed abundances with respect to their atomic number and mass number, and compared them to the abundances procured from solar and metal-poor halo star data. Both of these environments are known to house r-process elements, and an agreement between the observed abundance data and the abundance data from our simulation would support the theory …
