In the modern business world, maximizing profits is the highest priority. Businesses, especially small ones, should try to save money whenever possible. Along with cutting wages, removing competition, and increasing advertising and production, efficiency of company sites can save money. For example, a cheap 50 ft. by 100 ft. warehouse costs $35,000, but when coupled with the costs of maintenance and wages, increasing the number of warehouses significantly increases costs.

Clearly, warehouses are expensive, making it necessary to place them in optimal locations. In this problem, we attempt to reduce the number of warehouses while shipping to the entirety of …

Artificial Intelligence: Prospects, Pathways, Realities, Timur Javid '17, Tara Parkman '17, Nathaniel Smith '17 Apr 2016

Artificial Intelligence: Prospects, Pathways, Realities, Timur Javid '17, Tara Parkman '17, Nathaniel Smith '17

IMSAloquium Student Investigation Showcase

The specter of Artificial Intelligence (AI) looms before us, continuously growing in power, soon to match, and then exceed human capabilities. To explore this, we read and discussed books by experts, and learned about the exponential nature of technological progress and the difficulties of halting or even slowing it. Technological improvements trend towards an autonomous AI capable of replicating, if not exceeding human thought and interaction, a complex adaptive system with an input stream, isomorphic model of reality and output mechanism, fully capable of passing the Turing Test. How a system is organized is a key determinant of the processes …


Inferences Of Subglacial Processes Under The West Antarctic Ice Sheet From Grain Surface Textures, Aspen Wheeler '16 Apr 2016

Inferences Of Subglacial Processes Under The West Antarctic Ice Sheet From Grain Surface Textures, Aspen Wheeler '16

IMSAloquium Student Investigation Showcase

Subglacial sediment transport under Whillans Ice Stream in West Antarctica is inferred using samples collected from Subglacial Lake Whillans (SLW) and two sites at a location called “UpB”. The surface features on quartz grains between 125 and 1000 micrometers were described using a Scanning Electron Microscope. Mahaney’s Atlas of Sand Grain Surface Textures and Applications (2002) was used to uniformly and unbiasedly categorize surface features from SLW and UpB, for different grain sizes and depths in cores collected from subglacial till. Data showed three groups that can be used to delineate phases of the subglacial sediment. Phase one is shown …


Comparing Biodiversity Of Silurian Reefs In Illinois And Wisconsin Using Museum Collections And Unbiased Bulk Samples, Walker Weyland '17 Apr 2016

Comparing Biodiversity Of Silurian Reefs In Illinois And Wisconsin Using Museum Collections And Unbiased Bulk Samples, Walker Weyland '17

IMSAloquium Student Investigation Showcase

Silurian (Wenlock) fossil reefs from the Racine Formation in Illinois measure over 100 meters tall and draping flanks beds extend over a mile. Biodiversity studies of reefs in Southeastern Wisconsin reveal complex, diverse communities with over 191 species. We hypothesized that the larger reefs reflect a more optimal environment and may have had higher diversity than reefs in Wisconsin. We compared diversity between the reefs using, identified fossils from the Field Museum, which were collected in Herscer, Romeo, Thornton, Bridgeport, and Hawthorn. Then we compared the results with those from Watkin’s (1997) counts, collected from Horlick, Ives, Franklin, and Francy …


Field-Programmable-Gate-Array Implemented On Time-To-Digital Converter: Improving Its Resolution, Soomin Park '17 Apr 2016

Field-Programmable-Gate-Array Implemented On Time-To-Digital Converter: Improving Its Resolution, Soomin Park '17

IMSAloquium Student Investigation Showcase

The purpose of this investigation is to discover critical experimental factors that could lead to the variation of time measurement by a time-to-digital converter (TDC) implemented on field-programmablegate- array (FPGA). Two pulses were generated by a pulse generator, and the second pulse was given a 20 nanoseconds delay. In an ideal experiment, the mean of the entry data would have been 20 nanoseconds since the two channels (8,c) obtained pulses that were given the same delay. However, due to device errors and quantization errors, which is produced during analog-to-digital conversion, time difference between hits varied from 22.1 to 22.7 nanoseconds. …


Neural Networks And Machine Learning Applied To Classification Of Cancer, Sachin Govind '16 Apr 2016

Neural Networks And Machine Learning Applied To Classification Of Cancer, Sachin Govind '16

IMSAloquium Student Investigation Showcase

Using genome data to predict cancer type is an increasingly relevant practice as it provides a direct, noninvasive strategy to analyze genetic predisposition to malignant cancer types. More specifically, analysis of gene expression data across the genome can provide insight into the underlying gene interactions that propel the progression of tumors. A database containing expression levels for 16,063 genes was split into disjoint training and testing sets; these were subjected to a variety of machine learning methods and statistical analyses, including multinomial logistic regression across cancer phenotypes, k-means clustering analysis, optimization of a predictive support vector machine, and rooted random …


The Entangling Properties Of Knots And Links, Eshan Mehrotra '17 Apr 2016

The Entangling Properties Of Knots And Links, Eshan Mehrotra '17

IMSAloquium Student Investigation Showcase

It has been conjectured that quantum entanglement operators can be lifted to braiding operators by the way of the topological quantum field theory axioms set forth by Witten and Atiyah. Moreover, it can be readily shown that quantum link invariants need entanglement to construct topological invariants. Given these results and the already dense mathematical framework underlying topology and quantum field theory, we propose that, through the usage of quantum algebra and bracket models, we can identify a significant area of overlap where entangling R-matrix solutions to the Yang-Baxter equation can be used to construct invariants of knots and links. Such …


Optimal Concentrations Of Ethanol And Isopropanol For The Dissolution Of Pmma, Maya Costales '16 Apr 2016

Optimal Concentrations Of Ethanol And Isopropanol For The Dissolution Of Pmma, Maya Costales '16

IMSAloquium Student Investigation Showcase

Last year we studied the effectiveness of Alcohol/Water mixtures in dissolving PMMA. PMMA is a commonly used resist in electron beam lithography. Ethanol/Water mixtures in a 4:1 volume ratio developed PMMA such that they could replace mixtures of Methyl(isobutylketone) and Isopropanol. Raman spectroscopy revealed that Ethanol/Water mixtures in a 4:1 ratio and IPA/Water mixtures in a 3:1 ratio have different vibrations than those of pure Ethanol, IPA, and water. Our study this year will discuss the characteristics of Ethanol/Water and Isopropanol/Water solutions with dissolved Poly(methylmethracrylate). A fixed amount of 12,000 molecular weight PMMA was dissolved into a series of these …
