title: Graduate Recital
Creators: name: Davis, Donna Gatlin
Publisher: name: Utah State University
Year: 1977

description: Preparation for the graduate recital provides the Master's candidate an opportunity to exercise a variety of musical skills. Choosing the best possible program requires not only a working knowledge of the available repertory, but a personal assessment of the particular voice with its characteristic strengths and weaknesses. The final selection must reflect a fine balance of material difficult enough to provide a musical challenge and material with which a singer can feel comfortable in communicating.
Working toward the performance involves both intellectual preparation through research and physical preparation through vocal conditioning. It is not enough to anticipate vocal difficulties and then to rehearse and memorize the music, the singer must understand what he sings. Proper performance of the songs requires a study of the period and the genre of each composition, the composer and his use of musical devices within a particular piece, and the individual text with its mood or purpose. The primary source for study is the music itself, and this is supplemented by materials written about the author and his works.
An exhaustive study of each composition on the program is beyond the scope and intention of the recital report. Therefore, because of a special interest, the author has chosen to study one group of songs, Finzi's I Said to Love, in sufficient detail as to exhibit a maturing of analytic techniques.
Although Gerald Finzi was not an unusually prolific or heralded composer of the twentieth century, his vocal selections are beautifully endearing and skillfully crafted examples of the solo song. Within the realm of his craftsmanship was the gifted ability to provide a near perfect union of text and music, even with difficult material such as poems of Thomas Hardy. The purpose of this paper is to discuss general characteristics of Finzi's music as revealed in the six songs of I Said to Love and his particular affinity to the poetry of Thomas Hardy.
In order to discuss the song cycle I Said to Love with understanding, it is necessary to include general background information. Biographical considerations of both Gerald Finzi and Thomas Hardy are provided with a brief summary of their particular styles. Each song setting is analyzed first as poetry and then according to musical considerations. Comments on performance problems are included when they seem appropriate.

description: Guidelines for annotating epilepsy clinic letters to create annotation sets used for the development and testing of clinical NLP applications.

The guidelines detail entities and features (attributes) to be annotated. Numerous examples of correct annotations and possible errors are provided with each annotation type (entity). Entities discussed include Diagnosis (epilepsy, seizure types), Birth History (premature birth,  perinatal injuries), Epilepsy cause, Onset (age, time since, date), Investigations (EEG, MRI, CT), Patient History (comorbidities and major events affecting health),  Prescriptions, Seizure Frequency (number of seizures with temporal concepts), and When Diagnosed (age, time since, date). Lists of terms relating to entities and features are provided to aid in the annotation process. The guidelines were   developed  to be used with Markup (https://getmarkup.com/ )but should be suitable for other applications.

We used and updated the guidelines while annotating 200 synthetic clinic letters uploaded here (10.5281/zenodo.8381080) and are continuously updating the lists and examples to make the annotation process as easy as possible for researchers with little clinical knowledge.

Although designed to guide through the annotation of epilepsy documents, the guidelines can be adapted to other diseases, with changes to entities and with the temporal concepts relating to Onset, When Diagnosed, and Patient History most likely remaining the same.

“We knew it was coming, we just didn’t know what it would be like to live it” : the extreme weather worlds of senior tenants in Vancouver, British Columbia
Creators: name: Stern, Rachel Naomi
Publisher: name: University of British Columbia
Year: 2023

description: This thesis explores the ways in which recent extreme weather events in Vancouver, British Columbia (B.C.) are experienced, narrated and remembered in the context of already-existing inequalities, such as housing and economic injustice. The 2021 summer “heat dome” was the deadliest weather event in Canadian history and was responsible for the deaths of over 600 people, almost all of whom died indoors at home or in a hotel, according to the BC Coroners Service. Echoing studies of other heatwaves, social isolation and factors such as older age, underlying health conditions, and economic inequality have been identified as particular risk factors for the 2021 heat dome. In B.C.’s population centre, Metro Vancouver, the recently declared climate emergency by the City of Vancouver coincides with a housing emergency, with Metro Vancouver currently home to the highest average rents and the most evictions across Canada. Based on collaborative work with the UBC Centre for Climate Justice, this thesis examines senior tenants’ experiences, stories, and memories of extreme heat and home. Two focus groups and fourteen oral histories were conducted between February and April 2023, primarily in South Vancouver. Drawing on feminist political ecology, disaster studies, and memory and weather studies, I illuminate four key ways that participants experienced and remembered the 2021 heat dome: 1) disruption of everyday activities, 2) experiences of loss of control, often linked to their positions as tenants, 3) comparisons to other places and expected weather norms, especially as past memories informed experiences of present weather and 4) stories told through participants’ diaries of everyday life. Through these key pathways of experience and memory, I argue that understanding how participants experience extreme weather through an embodied, memory-rich, and political lens allows for better scholarly and policy understandings of how to support communities during events like the heat dome. I recommend that future work on heat policy, climate justice, and planning for extreme weather better incorporate narratives and embodied knowledges of senior tenants, and further consider the unjust power dynamics that can arise around relationships to housing and home.
Symmetric spaces of higher rank do not admit differentiable compactifications

description: Any nonpositively curved symmetric space admits a topological compactification, namely the Hadamard compactification. For rank one spaces, this topological compactification can be endowed with a differentiable structure such that the action of the isometry group is differentiable. Moreover, the restriction of the action on the boundary leads to a flat model for some geometry (conformal, CR or quaternionic CR depending of the space). One can ask whether such a differentiable compactification exists for higher rank spaces, hopefully leading to some knew geometry to explore. In this paper we answer negatively.

After Presenting Multiple Solution Strategies, What’s Next? Examining the Mathematical Connections Made by Preservice Teachers

description: When teaching through problem solving, effective mathematics teachers need to lead discussions that assist students in making connections between different solution strategies. However, while teaching a methods course for preservice teachers (PSTs), we noticed that after solving a problem and presenting various solution strategies, many PSTs seemed lost on how to proceed with the mathematics lesson. To address this issue, we designed an action research study where we implemented Smith and Stein’s (2011) five practices for orchestrating productive classroom discussions, and focused our attention on the fifth practice, making connections. Specifically, we designed an instructional intervention to examine the type of connections made by PSTs and how these connections changed as the course progressed to aid PSTs’ connection making skills. We identified three types of connections made by PSTs: superficial knowledge connections, procedural knowledge connections, and conceptual knowledge connections. Additionally, we observed a decrease in the amount of superficial knowledge connections and an increase in the amounts of procedural knowledge connections and conceptual knowledge connections made by PSTs throughout the course.

title: Infinite Product Spaces Under the Tychonoff and Goofynoff Topologies
Creators: name: Capps, James A.
Publisher: name: Utah State University
Year: 1973

description: The only topology considered for the infinite product of topological spaces in most current topology texts and research papers is the Tychonoff topology. Yet there is another topology which seems to be a much more topologically natural generalization of the usual "box" topology of finite products. We call this natural generalization the Goofynoff topology and exploit its properties. The use of the word "Goofynoff" (pronounced Goof'-n-off) is not universal and does not refer to any person of that name. In the few references to this topology that can be found, it is usually called simply the Box Topology. None of the popular topology texts provide much indication of why the Tychonoff topology is generally chosen instead of the more natural Goofynoff topology. This paper provides the reasons from a topologist's point of view. In Section III of this paper we compare the productivity of various properties under these two topologies.
This paper was motivated by a question asked in the notes for a topology class at Utah State University in the fall of 1972. This question, concerned with the connectedness of an infinite product of connected spaces (under the Goofynoff topology), went unanswered through two graduate classes. An example showing that such a space may fail to be connected is given in Section II. In some respects the example resembles the Hilbert Cube Iw and, for that reason, is called the Goofy Cube and is denoted by Gw. In order to emphasize the difference, we include a table at the end of Section II which compares the topological properties of Iw with those of Gw.

description: Graphs with large spectral gap are important in various fields such as biology, sociology and computer science. In designing such graphs, an important question is how the probability of graphs with large spectral gap behaves. A method based on multicanonical Monte Carlo is introduced to quantify the behavior of this probability, which enables us to calculate extreme tails of the distribution. The proposed method is successfully applied to random 3-regular graphs and large deviation probability is estimated.

Connecting the Tangent Function to Cardinality: A Method for Introducing Set Theory to High School Students
Creators: name: Deihl, Steve

Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2019

description: High school students often ask questions about the nature of infinity. When contemplating what the “largest number” is, or discussing the speed of light, students bring their own ideas about infinity and asymptotes into the conversation. These are popular ideas, but formal ideas about the nature of mathematical sets, or “set theory,” are generally unknown to high school students. The authors propose a method for introducing basic ideas in set theory to high school trigonometry students by connecting prior knowledge of the tangent function and the unit circle to Georg Cantor’s ideas about infinity. By doing so, high school teachers have an opportunity to inspire their students with rich mathematics.

We show that the affirmation is valid if one finds an interesting example in which inverting the order between spatial derivatives and integration is not allowed. Further, we consider the generalization of the multipolar expansion of the power radiated by a confined system of charges and currents to a higher arbitrary order.

description: Bare interfaces between water and hydrophobic media like air or oil are of fundamental scientific interest and of great relevance for numerous applications. A number of observations involving water/hydrophobic interfaces have, however, eluded a consensus mechanistic interpretation so far. Recent theoretical studies ascribe these phenomena to an interfacial accumulation of charged surfactant impurities in water. In the present work, we show that identifying surfactant accumulation with X-ray reflectometry (XRR) or neutron reflectometry (NR) is challenging under conventional contrast configurations because interfacial surfactant layers are then hardly visible. On the other hand, both XRR and NR become more sensitive to surfactant accumulation when a suitable scattering length contrast is generated by using fluorinated oil. With this approach, significant interfacial accumulation of surfactant impurities at the bare oil/water interface is observed in experiments involving standard cleaning procedures. These results suggest that surfactant impurities may be a limiting factor for the investigation of fundamental phenomena involving water/hydrophobic interfaces.
title: Optimizing Dam Siting in the Paru River in Brazil Using a Multi-Objective Approach
Creators: name: de Paula, Henrique
Publisher: name: Utah State University
Year: 2016

description: How should a decision-maker choose which hydropower plant to build in a given river? Hydropower plant expansion is a task that involves several stakeholders, objectives, and resources. It requires that decision-makers use not only experience and previous knowledge to come up with their final decision, but also the use of tools to help them to decide, as well as to support their choices. The present project developed a computation model to optimize the choice of hydropower plants that can be built within a given river, considering three different objectives - energy generation, flooded surface area and river connectivity. The input data required to solve the mathematical problem was previously obtained from other sources. The mathematical model developed is classified as multi-objective linear integer problem and was solved using a the branch-and-cut method implemented by a commercial linear solver. In order to deal with the multi-objective approach, the constraint method was used. The main outputs of the model are the trade-off curves between objectives and the Pareto sets, which can be used by decision-makers to better understand the existing tradeoffs imposed by the problem. The model was tested using the energy generated the flooded surface area and distance from mouth of each project studied in the hydropower inventory studies developed for the Paru River, a tributary of the left margin of the Amazon River, located in the state of Pará, Brazil. The results showed that there is a trade-off between energy generation and surface flooded area, as well as energy generation and river connectivity, both a direct consequence of the fact that more projects will be necessary to meet energy requirements. Connectivity and surface flooded area, however, are not competing, since an improvement in both metrics will result in habitat quality improvement. The results were also compared to the ones obtained in the inventory studies, showing that different methods (ranking methods x multi-objective optimization models) can yield different policies. The main reasons for these differences are related to the solution method used since each one will take into account different management goals and performance metrics.

Our main result shows that its special values at nonnegative integers are always expressible by alternating Euler sums. More precisely, every such special value of weight w>2 is a finite rational linear combination of alternating Euler sums of weight w and depth at most two, except when the only nonzero argument is one of the two last variables in which case $ζ(w-1)$ is needed.

title: Code-Switching and Its Challenges: Perspectives on Translanguaging in the EFL/ESL Classroom
Creators: name: Spooner, Michael
Publisher: name: Utah State University
Year: 2017

description: Structured in sections that represent the author’s teaching perspectives and research perspectives, the portfolio comprises reflective pieces written at the end of the Master of Second Language Teaching program and other pieces written as coursework during the author’s study in that program. In the first section, the author describes the principles that guide his own teaching and, in light of those principles, he reviews his experience as a learner, reports on observations of other teachers, and assesses his own performance based on observations done by others. The second section offers a set of four research papers that progressively develop and explore questions of code-switching and its potential for research-based application in EFL/ESL pedagogy.
A long history of bilingual pedagogy in ESL exists, the author points out, but has largely been neglected since the end of the 19th century. Current research in translanguaging and translingualism offer a solid rationale for effective use of learners’ first language in EFL/ESL teaching, with particular attention to code-switching. His position questions the traditional English-only classroom, arguing that monolingual policies are rooted in unexamined cultural fears and biases. The author suggests that a more appropriate balance can be achieved through teacher education based on examples in the research and in recent pedagogical work.

Wiener filter has been used to remove the background noises from the source speech utterances. Speech features have been extracted using standard speech parameterization method such as LPC, LPCC, RCC, MFCC, (delta)MFCC and (delta)(delta) MFCC. For each of these techniques, the performance of the proposed system has been compared. In this codebook design method, Genetic Algorithm has the capability of getting global optimal result and hence improves the quality of the codebook. Comparing with the NOIZEOUS speech database, the experimental result shows that 79.62 percent accuracy has been achieved.

description: Driving safety has drawn much public attention in recent years due to the fast-growing number of cars. Smoking is one of the threats to driving safety but is often ignored by drivers. Existing works on smoking detection either work in contact manner or need additional devices. This motivates us to explore the practicability of using smartphones to detect smoking events in driving environment. In this paper, we propose a cigarette smoking detection system, named HearSmoking, which only uses acoustic sensors on smartphones to improve driving safety. After investigating typical smoking habits of drivers, including hand movement and chest fluctuation, we design an acoustic signal to be emitted by the speaker and received by the microphone. We calculate Relative Correlation Coefficient of received signals to obtain movement patterns of hands and chest. The processed data is sent into a trained Convolutional Neural Network for classification of hand movement. We also design a method to detect respiration at the same time. To improve system performance, we further analyse the periodicity of the composite smoking motion. Through extensive experiments in real driving environments, HearSmoking detects smoking events with an average total accuracy of 93.44 percent in real-time.

description: A model for the evolution of low-luminosity radio galaxies is presented. In the model, the lobes inflated by low-power jets are assumed to expand in near pressure-balance against the external medium. Both cases of constant external pressure and decreasing external pressure are considered. Evolution of an individual source is described by the power-size track. The source appears as its lobe is inflated and radio luminosity increases to above the detection level; the source then moves along the track and eventually disappears as its luminosity drops below the detection limit. The power-size tracks are calculated including the combined energy losses due to synchrotron radiation, adiabatic expansion, and inverse Compton scattering. It is shown that in general, the constant-pressure model predicts an excess number of luminous, small-size sources while underpredicting large-size sources in the power-size diagram. The predicted spectra are steep for most sources, which is inconsistent with observations. By comparison, the pressure-limiting model fits observations better. In this model, low-luminosity sources undergo substantial expansion losses in the initial phase and as a result, it predicts fewer luminous, small-size sources. The resultant spectra are flat for most sources except for the oldest ones, which seems consistent with observations. The power-size tracks, in contrast to that of high-luminosity radio galaxies, are characterized by a slow increase in luminosity for most of the source's life, followed by a rapid decline when the synchrotron or inverse Compton scattering losses set in.

description: A pressure resistant and optically accessible deterministic lateral displacement (DLD) device was designed and microfabricated from silicon and glass for high-throughput fractionation of particles between 3.0 and 7.0 µm comprising array segments of varying tilt angles with a post size of 5 µm. The design was supported by computational fluid dynamic (CFD) simulations using OpenFOAM software. Simulations indicated a change in the critical particle diameter for fractionation at higher Reynolds numbers. This was experimentally confirmed by microparticle image velocimetry (µPIV) in the DLD device with tracer particles of 0.86 µm. At Reynolds numbers above 8 an asymmetric flow field pattern between posts could be observed. Furthermore, the new DLD device allowed successful fractionation of 2 µm and 5 µm fluorescent polystyrene particles at Re = 0.5–25.

description: Smart Grids are the next generation electrical grid system that utilizes smart meter-ing devices and sensors to manage the grid operations. Grid management includes the prediction of load and and classiﬁcation of the load patterns and consumer usage behav-iors. These predictions can be performed using machine learning methods which are often supervised. Supervised machine learning signiﬁes that the algorithm trains the model to eﬃciently predict decisions based on the previously available data.
Smart grids are employed with numerous smart meters that send user statistics to a central server. The data can be accumulated and processed using data mining and machine learning techniques to extract meaningful insights. Forecasting of future grid load (electricity usage) is an important task for gaining intelligence in the gird. Accurate forecasting will enable a utility provider to plan the resources and also to take controlled actions to balance the supply and the demand of electricity. This forecasting can be achieved using machine learning based predictive models.
In this project, a predictive system is designed that uses data mining and machine learning techniques to process the smart meter data and to use it as training data for the model. The main objective of this project is to forecast short term to mid-term load for the grid entity. The outcomes are backed with visualizations to make the data and results more user readable.
Theory of Professional Competence in Teaching of Mathematics: Development and Explication through Cross-cultural Examination of Teaching Practices in India and the United States
Creators: name: Ahuja, Renu
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2019

description: This paper describes the theory of professional competence in teaching of mathematics developed through a cross-cultural examination of teaching practices of mathematics teachers recommended as competent by their principals in two selected high-achieving high schools of India and the United States. A detailed study of teacher cases from both of the research settings yielded a rich conceptualization of the relationship between teachers’ professional knowledge base and professional competence in the teaching of mathematics. The substantive theory explains the processes of both the development and the display of professional competence and enables predictions of the ways teachers would most likely utilize to meet the performance expectations of their work environments. The study makes a unique contribution to the field of teacher education and views professional competence as a dynamic interplay of various components of teachers’ professional knowledge base activated in actual teaching situations in the context of the classroom, school, and wider social culture.

description: Numerical data for the heat transfer as a function of the Prandtl (Pr) and Rossby (Ro) numbers in turbulent rotating Rayleigh-Benard convection are presented for Rayleigh number Ra = 10^8. When Ro is fixed the heat transfer enhancement with respect to the non-rotating value shows a maximum as function of Pr. This maximum is due to the reduced efficiency of Ekman pumping when Pr becomes too small or too large. When Pr becomes small, i.e. for large thermal diffusivity, the heat that is carried by the vertical vortices spreads out in the middle of the cell, and Ekman pumping thus becomes less efficient. For higher Pr the thermal boundary layers (BLs) are thinner than the kinetic BLs and therefore the Ekman vortices do not reach the thermal BL. This means that the fluid that is sucked into the vertical vortices is colder than for lower Pr which limits the efficiency of the upwards heat transfer.

Creators: name: Thomas, Casedy A.
name: Berry III, Robert Q.
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2019

description: This article uses Culturally Relevant Pedagogy (CRP) and Culturally Responsive Teaching (CRT) as the theoretical frameworks and qualitative metasynthesis as the methodological framework to synthesize qualitative research published between 1994 and February of 2016. Initial searches produced 1,224 articles, but through a process of appraisals, 12 articles were synthesized to understand how researchers interpret mathematics teaching practices that support CRP and CRT in pre-kindergarten through 12th grade. There were five findings focused on teacher practices, classroom interactions, and student experiences with CRP and CRT within mathematics education, including: caring, context, cultural competency, high expectations, and mathematics instruction.

description: Curriculum change is inevitable in schooling. For content areas such as mathematics that are already under the national spotlight, transitioning to new curriculum materials while concurrently enacting instructional reform creates both a challenge and an opportunity. This paper discusses how partnerships between two state universities and respective neighboring school districts resulted in the creation and implementation of graduate courses for teachers targeted at curricular and instructional reform specific to each district. Common course components between both university-district partnerships were identified in the areas of mathematics research, practice, and leadership advocacy and found to be instrumental in supporting instructional reform and fostering sustained development. Implications for collaborative partnerships, curriculum implementation and research are discussed.

The Life of Maryam Mirzakhani
Creators: name: Gibbons, Alanna
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2019

description: Maryam Mirzakhani is the first and the only female winner of the Fields Medal since its establishment in 1936. She is arguably one of the greatest mathematicians of our generation. This biographical paper outlines her life and work. Her mathematical theorems and noteworthy accomplishments are just as impressive as her determination, imagination, and optimistic outlook on life. Mirzakhani’s success came from her passion, creativity, and playful approach to mathematics. She felt the most rewarding part of mathematics was the enjoyment of understanding or discovering something. Mirzakhani’s work was visual and focused on patterns and ideas rather than on numbers and algorithms. She constructed mathematics in an artistic way, and her goal was to always find truth and beauty in the world. Mirzakhani will forever be an inspiration to anyone who has studied her work and read her story.

Persistent Current in Metallic Rings and Cylinders
Creators: name: Maiti, Santanu K.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We explore the behavior of persistent current and low-field magnetic response in mesoscopic one-channel rings and multi-channel cylinders within the tight-binding framework. We show that the characteristic properties of persistent current strongly depend on total number of electrons $N_e$, chemical potential $μ$, randomness and total number of channels. The study of low-field magnetic response reveals that only for one-channel rings with fixed $N_e$, sign of the low-field currents can be predicted exactly, even in the presence of disorder. On the other hand, for multi-channel cylinders, sign of the low-field currents cannot be mentioned exactly, even in the perfect systems with fixed $N_e$ as it significantly depends on the choices of $N_e$, $μ$, number of channels, disordered configurations, etc.

title: The Historical and Familial Context of Benjamin Franklin Riter, 1859-1925
Creators: name: Keller, Ian
Publisher: name: Utah State University
Year: 2017

description: Benjamin Franklin Riter was born in Salt Lake City on 31 August 1859.1 His parents had traveled to Utah in 1847 as part of the Latter-day Saint migration.2 He worked with doctors and druggists in his youth, and grew up to be the manager of a small chain of drug stores. The Riter Brothers Drug Company was incorporated in Logan in 1891 and remained in business at least until 1918. The pharmacy operated five stores: two in Utah, at Garland and Logan, and three in Idaho, at Preston, Montpelier, and Franklin. They kept prescription records, which were pasted into four large ledgers, and are now held in Utah State University’s Special Collections and Archives. The available ledgers cover 1903-1904, 1905-1907, 1913-1914, and 1915-1918.3 This was a family business. Benjamin Franklin Riter was the manager, his brother William Wollerton Riter was the president, and another brother, Samuel Wollerton Riter, was the secretary and treasurer.
Most of the prescriptions included in the Riter Brothers’ ledgers are handwritten on the company's own stationary, blue papers about the size of three-by-five cards. The recipe, dosage, and instructions for taking the medication were handwritten on the papers, and the papers were signed by the prescribing physician. Pharmacists then initialed the papers and stamped them with a five-digit consecutive order number. Dates were sometimes stamped onto the prescription note. The patient’s name was not usually recorded, though other pharmacies, such as Logan’s “Co-Operative Grocery and Drug Company” included a field for the patient’s name on their prescription slips. The handwriting is not easy to read, and the task is made harder if one is not familiar with contemporary terms for local pharmaceutical ingredients. However, the records are rich and offer multiple possibilities for analysis.

Reflecting on Action: Implications from the Child Mathematics Inquiry Portfolio
Creators: name: Gujarati, Joan
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2019

description: This article examines how the Child Mathematics Inquiry Portfolio (CMIP), a semester-long field experience project attached to an elementary mathematics methods course, can impact preservice teachers’ understanding about teaching and learning mathematics and set them on more positive mathematics teaching journeys as they prepare to enter the field. This action research study, grounded in reflective practice, was contextualized in undergraduate and graduate elementary mathematics methods courses with 92 participants over two academic years. Data came from preservice teachers’ written reflections on the child mathematics inquiry process. Findings reveal that the CMIP impacted the preservice teachers’ mathematics teaching and learning in four major areas: bridge between mathematics methods course, textbook, and actual classroom experience; mathematical confidence; greater understanding of how teachers shape students’ mathematics dispositions; and personal. Implications for mathematics teacher education are discussed.

title: Application: Solving for a Local Companys Optimal Storage Strategy
Creators: name: Ferrin, Dakota
Publisher: name: Utah State University
Year: 2017

description: This project used historical spot and futures price data of two fairly closely correlated commodities to simulate many possible spot and futures price paths that could have occurred over a given time frame. These simulated prices were then used to test various commodity storage strategies available through futures contracts. This paper explains how results, including values such as the mean terminal cumulative profit and the standard deviation of the mean terminal cumulative profits for each strategy, can be interpreted to help determine a local company’s optimal storage strategy.
This paper specifically provides a way for a local company to find this optimal storage solution for 3 products they sell. When this company runs the given Python computer code files using their historical inventory level data and historical sales data, they can follow the example analysis in this paper to help decide how their company should utilize futures contracts to store each of the 3 commodities.
This project assumes that the company periodically adjusts the number of futures contracts they use based on the company’s inventory level of a commodity. This would require the inventory level and the number of futures positions to be monitored by the company. This management of tracking inventory and adjusting the number of futures contracts being used could take both extra time and extra money to pay employees for that time, which presents two potential challenges for the implication of the results of this project. However, this project could serve as an important aid to this company, because it may help them obtain higher profits. This helps not only the company’s bottom line, but also the employees working for this company and the community in which the company is located.
