Controlled-Airflow Sensor Enclosure (Case) Design Document, Catryn N. Cattoor

Mechanical Engineering and Materials Science Independent Study

The purpose of this document is to organize the theory, industry practices, and research related to designing a device that pulls air through a pipe, containing an environmental sensor, at a rate controlled by a computer fan. Using such a device to regulate the airflow over a sensor can improve the accuracy of field readings, as sensors are often unintentionally sensitive to multiple external conditions. Changes in wind direction and speed or heating due to solar radiation, for example, can cause errors in gas concentration and temperature readings, warranting the need to correct for these factors without decoupling these sensors …

Work Extracting And Second Law-Like Inequalities From Non-Extensive Small Systems With Feedback, Mehdi Mirzaee, Saman Amiri

Turkish Journal of Physics

The Gibbs-Boltzmann entropy effectively characterizes systems with a significant reliance on initial conditions. Nonetheless, the majority of materials generally exhibit behavior that is independent of their initial conditions. Conversely, Tsallis entropy—a nonextensive entropy that underpins nonextensive statistical mechanics—provides a comprehensive framework for modeling systems that engage with their environment. In this study, we derive the Tsallis formulation of the Clausius inequality in a quantum context and establish an upper limit for the work that can be extracted from a small system within the framework of nonextensive quantum statistical mechanics. Furthermore, by utilizing a principle from quantum information theory—which posits that …

Computational Investigation Of The Structural And Electronic Effects Of Phenyl, Alkyl, And Halogen Fully Substituted Acenes, Emily A A Jarvis, Viraj Jain, Georgia Grace Tully, Peter W. Jarvis

Chemistry and Biochemistry Faculty Works

Acenes are a class of polycyclic aromatic hydrocarbons that may hold promise as organic semiconductors (OSCs) in solar cells and electronic devices. Their instability and poor solubility present challenges that may be improved by replacing the hydrogens with phenyl, halogen or alkyl substituents to sterically induce a helical twist to these otherwise planar molecules. This twisted structure also impacts the optical properties of these molecules. We employ time-dependent density functional theory (TD DFT) to investigate acenes spanning from naphthalene to heptacene. We focus on the structural and electronic effects of fully substituting these molecular backbones to create seven distinct substituent …

Quantified Possibility Neutrosophic Soft Set Based Decision Support System For Enhanced Accuracy In Sustainable Supplier Selection Decision Analysis, Neha Andaleeb Khalid, Muhammad Saeed

Neutrosophic Systems with Applications

To deal with the concepts of vulnerability, ambiguity, and indeterminacy that are typical in complex decision analysis contexts, neutrosophic set-like structures are frequently used. Although neutrosophic sets are particularly good at handling indeterminate circumstances, indeterminacy plays a part in making the decision making process imprecise and ambiguous. This paper develops a more advanced technique to improve the accuracy of decision analysis problems: the Quantified Possibility Neutrosophic Soft Set Decision Support System (Q^t PNSSDSS). In order to reduce the element of indeterminacy present in conventional neutrosophic sets, the proposed DSS is based on the Quantified Neutrosophic Set, which employs a …

Digital Trading Platform Selection Under Neutrosophic Numbers And Multi-Criteria Decision-Making Methodology: An Illustrative Example, Eman Sayed, Karam M. Sallam, Ibrahim Alrashdi

Neutrosophic Systems with Applications

Uncertainty, vagueness, and incomplete information are pervasive in real-world decision-making scenarios, particularly in multi-criteria decision-making (MCDM) contexts involving expert judgments. To address these challenges, this study introduces a comprehensive decision-making framework that integrates Triangular Neutrosophic Numbers (TNNs) with the Weighted Aggregated Sum Product Assessment (WASPAS) method. The framework begins by capturing expert evaluations using TNNs, which effectively represent the degrees of truth, indeterminacy, and falsity inherent in subjective assessments. These evaluations are then transformed into crisp values using a novel score function that preserves the embedded uncertainty. The resulting decision matrices are aggregated into a unified structure to ensure consistency …

Implications Of Mexican Hat-Like Band Structure On Thermoelectric Properties, Muhammad Hilal, Oğuz Gülseren

Turkish Journal of Physics

Electronic band structure of low dimensional materials significantly impacts their thermoelectric performance. A Mexican hat-like band structure, characterized by a ring-shaped extremum in momentum space, offers distinct advantages due to its singularity in the density of states at the band edge and its ability to enhance energy-dependent transport. This work investigates a two-dimensional tight-binding model hamiltonian that incorporates both nearest-neighbor (t1) and next-nearest-neighbor (t2) hopping. The ratio of the hopping amplitudes, ξ = t2/t1, serves as a tunable parameter that modulates the shape and depth of the Mexican hat dispersion. We use an analytical expression for the energy band of …

The Changing Style Of Change In Style: A Critical Case Study On The Aesthetics Of De-Radicalization Experiences, Bernardo Alba

Electronic Theses and Dissertations Archive

This dissertation explores how aesthetic experiences—not just belief-systems or ideologies—influence both the process of radicalization into, and de-radicalization out of, Far-right nationalist subcultures. It introduces the concept of “aesthetic conversion”: a profound transformative shift in how people experience and express themselves through artistic media and stylistic taste broadly understood (including but not limited to fashion, tattoos, music, dance, creative writing, public speaking, etc.). I argue that such transformations in aesthetic sensibility can spark profound ideological changes, including the possibility of fostering disengagement from such far-right movements. With this concept, I aim to show that aesthetic concerns, far from being incidental …

Cross-Cultural Dialogue In Sound: An Analytical Exploration Of Tan Dun’S Elegy: Snow In June, Weipeng Liu

Electronic Theses and Dissertations Archive

This dissertation explores Tan Dun’s cross-cultural synthesis in contemporary music, focusing on his work Elegy: Snow in June (1991) to illuminate his role in redefining global musical dialogues. Situating Tan Dun within the broader trajectory of Chinese-Western musical encounters, the research addresses gaps in existing scholarship by integrating historical, analytical, and performative perspectives. Through meticulous score analysis, cultural-historical contextualization, and insights from performance practice, the study reveals how Tan Dun hybridizes Chinese pentatonic modes with Western harmonic frameworks, subverts orchestral hierarchies through unique timbres (such as stones and paper), and synthesizes Beijing opera’s jinda, manchang (“hasty stroke with slow singing”) …

Some Properties Of Neutrosophic Cubic Hypersoft Sets, Lubna Nayab, Muhammad Gulistan, Fawad Hussain

Neutrosophic Systems with Applications

This study addresses the limitations of NCS in managing uncertainties associated with multiple attributes and their further bifurcation. To address this challenge, we propose a generalization of the neutrosophic cubic soft set, introducing the concept of "neutrosophic cubic hyper soft set." Within this framework, we define internal and external neutrosophic cubic hypersoft sets, along with operations such as P-intersection, P-union, P-restricted union, P-extended intersection, P-OR operator, P-AND operator, R-intersection, R-union, R-restricted union, R-extended intersection, R-OR operator, R-AND operator, complement, and relative complement of neutrosophic cubic hyper soft sets. The study explores and presents relevant results, demonstrating the enhanced capability of …

Application Of Multi-Criteria Decision Analysis For Quantifying Responsibility In Ml-Based Intrusion Detection System, Mona Mohamed, Zekra Sakr

Neutrosophic Systems with Applications

With the swift growth in Internet of Things (IoT), certifying secure and trustworthy networks has turned to be a critical challenge, particularly as IoT devices are increasingly vulnerable to sophisticated cyberattacks. As a remedy, intelligent intrusion detection systems (IDS) evolved as promising solutions in recent years, but deciding on the appropriate model remains difficult because of competing performance and trustworthiness criteria. To this end, this paper explores a novel application of an ML-augmented decision-making framework to enhance security-related decision-making in IoT environments. The framework systematically evaluates and ranks ML-based IDS systems according to different evaluation criteria with distinct trade-offs, including …
