- ItemForecasting CAD/USD exchange rate(2023) Wu, Joyce; Anton, CristinaThe exchange rate of Canadian dollars was closely bound up with the US dollars for the past decades. The last time that the Canadian dollar was worth more than the US dollar was in July 2011. It then experienced its fastest decline in modern-day history as commodity prices rapidly deteriorated. We use time series analysis to study the variation of CAD/USD exchange rate since 2010. We fit an ARIMA model and analyze how different economic and social policies in both countries affect the exchange rate.
- ItemMeasuring the activity of Saccharomyces cerevisiae in relation to home-based additives by measured net weight loss(2022) Mainwaring, ShaunThis research study is to measure the activity of saccharomyces cerevisiae through selected additives which have been added in the hydration step of making bread dough. The saccharomyces cerevisiae is sensitive to sugars (Mazzoleni, S. et al.2015) and by using multiple possible additives that can be found at home, we can compare which ones give a healthier yeast and therefore a better rise to the dough. As the saccharomyces cerevisiae ferments, it consumes the sugars naturally in the dough and creates an acidic environment to maintain its growth and produces CO2 as a product of this reaction, which is the cause for the rising dough. This can be tracked by how active the yeast is to its mean weight loss by measuring the weight loss of the three separate batches and comparing the results through a Multiple Comparisons of Means: Tukey Contrasts test to see if the significance to what is added to what was added to help the fermentation process of the yeast. We can see that easily soluble sugars are the best choices for promoting the health of the saccharomyces cerevisiae in by the test with F(9,20)=14.49, p<0.0001.

- ItemLennon v. McCartney(2020) Kroetch, KimberlyIn this analysis, the chord progressions used in songs by the Beatles are modelled as Markov chains to identify potential differences between songs for which John Lennon had more influence and those for which Paul McCartney had more influence. A preliminary comparison of random samples of songs from each artist did not identify noteworthy differences between Lennon and McCartney; most pieces resulted in regular Markov chains. This analysis then focusses on two songs from the Beatles – “Norwegian Wood”, primarily written by John Lennon, and “Good Day Sunshine”, primarily written by Paul McCartney – which deviated from this pattern. Similar patterns were found between the two songs despite major differences in the chords that made up each state space. In general, however, McCartney’s song had more variety in terms of the number of chords used and the paths taken between tonic chords.
