Dig Limits Optimization Using Binary Integer Linear Programming Method In Open Pit Mines, Hussam Naif Altalhi

Masters Theses

"Dig limits optimization is the process for classifying different materials (e.g., ore, stockpile material, and waste) into appropriately sized contiguous zones for open pit mining. The efficient determination of dig-limits is crucial for profitable and sustainable resource extraction in mining. Previous research has focused on defining dig-limits manually or using optimization approaches, but these methods are limited to only handling two material destinations (ore and waste). Thus, there is a need for operations research methods that consider the selectivity of mining equipment and can optimize dig-limits for metal mining operations with more than two material destinations. Consequently, the objective of …

A Binary Integer Linear Programming Model For Optimizing Underground Stope Layout, Theophilus Mensah

Masters Theses

"Underground mine planning engineers face significant challenges when determining what geometry provides the most profitable and safe stope for extraction. Several techniques and optimization algorithms have been developed in recent years, but most fail to find optimal solutions because they are heuristic or LP-based without efficient geometric constraints. This thesis work proposes a two-dimensional binary linear programming (BILP) model for determining the optimal combination of blocks in a stope that maximizes the economic value of the layout of stopes for a sublevel deposit. The work draws from Queyranne and Wolsey’s (2017 & 2018) formulations of tight constraints for bounded up/down …

The Deep Bsde Method, Daniel Kovach

Masters Theses

"The curse of dimensionality is the non-linear growth in computing time as the dimension of a problem increases. Using the Deep Backwards Stochastic Differential Equation (Deep BSDE) method developed in [HJE18], I approximate the solution at an initial time to a one-dimensional diffusion equation. Although we only approximate a one-dimensional equation, this method extends well to higher dimensions because it overcomes the curse of dimensionality by evaluating the given partial differential equation along "random characteristics''. In addition to the implementation, I also present most of the mathematical theory needed to understand this method"-- Abstract, p. iii

Rather, the research for this thesis reviews the miracles of Jesus and Kṛṣṇa as documented in their respective scriptures to determine which can authoritatively claim to be God, the Creator of the universe, and thus the one true source of the miraculous on Earth. Further, both claim to be not only God the Creator but Savior. It is the contention here that the Creator has the desire to redeem and …

The Problem Of Deification Within The Church Context In India: An Implausible Deification, Sadananda Rao Matangi

Masters Theses

The self-deification has been the main point on which several related issues have been discussed. No humans are equal with God but are only the servants of God. Even Jesus Christ agreed that the Father is greater than He. The concept of self-deification cannot be used overtly or covertly for self-elevation, Sacro-egoism, Sacro-egotism, self-advantage, or self-probability. On accepting Jesus as one’s personal Lord and Savior, a person may get the blessing of forgiveness of sins, sanctification, salvation, filling of the Holy Spirit, assurance of resurrection, and being with the Lord (on the Second Coming). That does not mean they are …

Traditional Vietnamese Music And Its Incorporation Into Christian Worship, Elijah Khang Chau

Masters Theses

The thesis addresses the concern of incorporating traditional Vietnamese instruments into Christian worship. Most worship done in Vietnamese churches in the US is primarily westernized, and it lacks cultural elements to reflect the Vietnamese culture. Another concern is that the younger generation does not know much about Vietnamese culture; this is an issue because many Vietnamese descents do not know which culture they belong to. The idea behind traditional Vietnamese instruments incorporated into Christian worship will encourage Vietnamese churches to use Vietnamese traditions to further God’s Kingdom so that the Vietnamese congregation can worship and glorify God in their native …

Healing Artists Through Art, Corey Aaron Cundiff

Masters Theses

Men die by suicide nearly four times more than women, with higher rates among artists. There has been an increase in the rate of suicide over the years, primarily linked to depression and mounting societal expectations imposed upon men. The prevalence of social media and the awareness that comes with indicates that the issue of suicide may never disappear unless action is taken. This paper examines the need for art therapy to counter depression among male artists. No longer do we need to rely strictly on medication and talk therapy to treat depression. Many art therapy techniques have proven quite …

Living In Untranslatability--Performance Art In China And Usa, Ziyun Ma

Masters Theses

This thesis embodies discontinuities in performance art and its non-equivalent Chinese term “行 为艺术” between language and cultural context into a migrating journey. A comparative analysis on the disciplinary history of performance art studies in the US and China laid a foundation in exploring the dynamics of marginality in two contexts. Extracting from the narrative mechanism and body view of Chinese performance art, I demonstrate how the philosophy of living (生) inspired many artistic creation, which also echoes my research journey. And from our mutual living experience, I pose the concept of constructive untranslatability that applies positionality and situated knowledge …

“Little Old Wales”: Expressions Of Nationalism, Language And Pride In Welsh Football, Abigail Mathieson

Masters Theses

Welsh football, through its use of material culture, language, and acknowledgements of history, has become a major force in representing Welsh national identities locally and globally. This thesis expands on Benedict Anderson’s idea of the “imagined community” through contemporary research from academic sources and from voices throughout the Welsh footballing community. It highlights the significance of the sport in national identity, especially within smaller nations such as Wales with histories of post-colonialism. Along with this, football shows the role cultural nationalism plays in the nation of Wales and in its independence movements.

Development Of S.T.E.A.M. Daises In Formal And Informal Environments For Educating Primary I Learners, Frances Neville

Masters Theses

The federal government has made education a competition among ourselves. Learning is not a rivalry to be imposed on our physical and cognitive development as humans. Escalating beliefs recognize education is more encompassing than CCSS, assessments and the grade level time frames in which standards are to be taught. On the precipice of anti-intellect, low expectations, and what has been termed “The Dumbing of America” an investigation into what it would take to close the achievement gap and increase student learning is overdue.

The goal for my Michigan based project, S.T.E.A.M. Daises, was to develop a program focusing on the …

Behavioral Economic Factors In Collective Bargaining, Cristal Cardoso Sao Mateus Cardoso Sao Mateus

The present study evaluated the effects of delay, stake, and hypothetical group size on labor valuation in the context of increasing and decreasing labor demand. Challenges in collective bargaining are associated with work stoppages, which can cause economic losses, lack of service, and worker stress. Participants were asked to value their labor given a set of conditions in two experiments. Participants in experiment 1 (n = 49) valued their labor in both increasing and decreasing demand context. Conversely, participants in experiment 2 (n = 139) valued their labor in only one of the contexts. Delay to changes, stake size, and …

Wake Up America: Conceptualizing The Social Determinants Of Sleep, Nicole Eve Bray

Masters Theses

This paper is an attempt to understand racial, ethnic and gender disparities in sleep as a sociological problem. Public health and sociological researchers have looked at the connection between sleep disparities among minorities and the impact it has on health. However, they haven’t explained and applied the social structural factors that cause these disparities, as well as address how stress can serve as a moderator. In my investigation, I found that sleep troubles differ across race, ethnicity and gender. These differences relate to the distinguishable life situations of women and minorities in American society, such as stressful life circumstances that …

Truth From Fiction: The Apologetic Use Of Christian Allegorical Literature In The 21st Century, Terri Nicole Boutte

Masters Theses

Christian allegorical literature is a genre that explores apologetic claims in a unique and creative way. Although this genre has attracted many readers over the years, there is hesitation and reluctancy to accept Christian allegorical literature as a genre that should be used as an apologetic method. Namely, the didactic intent of this genre has caused some critics to question whether Christian allegorical literature promotes critical reading and thinking skills in a way that leads readers to make their own spiritual decisions. Some skeptics believe that sharing theistic truths that are disguised by fictional storylines is a creative way to …

The Waiting Period Of Death Row Inmates, Ashlee Patino

Masters Theses

The death penalty is the highest form of capital sentencing and punishment in the United States. Since 1973, a little less than half of U.S. states are responsible for passing death sentences and executions. Nevertheless, the growing number of death row inmates is at an all-time high since the late 70s (DPIC, 2022). Although academia and scholarly research has advanced the general understanding of death penalty sentencing, racial disparities resulting in a death sentence and execution has not been studied as comprehensively. Despite the strides in progress made by academia and scholarly research on the death penalty, there are areas …
