Modeling Distances Between Various Attractions And Nearest City Parks Using Exponential Distribution, Ashley Hall
Modeling Distances Between Various Attractions And Nearest City Parks Using Exponential Distribution, Ashley Hall
Scholars Week
We examine the park data in Twin Cities Metropolitan Area (TCMA) to understand the distances between various attractions (water features, transit stops, bike paths, sport fields, etc.) and nearest city parks. We verify our research hypothesis that these distance variables are exponentially distributed using histograms and chi-squared goodness-of-fit test. Our findings suggest that most of the distance variables are indeed exponentially distributed except the one that measures the distance between the metropolitan area and the nearest city parks. Based on that, we further hypothesize that the locations of the various attractions relative to the nearest city parks follow the spatial …
Polycarbodiimides And Polyguanidines : Their Reactivity And Applications In Covalent Adaptable Networks, Alberto Melchor Bañales
Polycarbodiimides And Polyguanidines : Their Reactivity And Applications In Covalent Adaptable Networks, Alberto Melchor Bañales
Scholars Week
We have recently discovered a new chemical transformation in which N,N’,N’’ tri-substituted guanidines undergo a thermal exchange reaction. Kinetic investigations indicate that the transformation is first order with respect to the guanidine, indicating a dissociative mechanism in which a carbodiimide and amine are formed as intermediates. This new reaction has been applied to polymer systems. Polycarbodiimides were shown to undergo postpolymerization modification with amines to form polyguanidines at room temperature under an hour. Polyguanidines undergo the newly found chemical transformation to form different substituted polyguanidines. This exchange reaction will be applied to the preparation of a covalent adaptable network by …
Spectral Analysis Of Stratigraphy At Eberswalde Crater, Mars, Cory Hughes
Spectral Analysis Of Stratigraphy At Eberswalde Crater, Mars, Cory Hughes
Scholars Week
We will analyze spectral characteristics of stratigraphy in the catchment and deposit at Eberswalde Crater, Mars. This crater is a frequent contender for the preferred destination of future Mars rover and human science missions in the search for evidence of life on the Red Planet.
