Ultrahigh-performance concrete (UHPC) offers significant potential to address a variety of needs in bridge design, construction, and performance enhancement. Bridge owners have shown willingness embrace novel solutions that could specific challenges related the cost, speed durability, service life their projects. There are hundreds bridges worldwide that, largely past decade, utilized UHPC. These applications range from minor field-cast closures precast segments for long-span kilometer-long...

Abstract Meaningful inclusion of neurodivergent students in engineering requires us to move beyond a focus on accommodations and accessibility embrace strength-based approach toward neurodiversity. A large body literature suggests that individuals, including those with attention deficit hyperactivity disorder (ADHD), dyslexia, or autism spectrum (ASD) possess wide range unique strengths may be assets engineering. These include divergent thinking, risk-taking, 3-dimensional visualization...

A growing body of literature suggests that neurodiverse learners may possess assets are highly desirable within engineering disciplines. Even so, despite the potential individuals to contribute innovation in science and engineering, students, such as those with attention deficit hyperactivity disorder (ADHD), autism, or dyslexia, remain underrepresented majors. We argue predominant perception neurodiversity a disability limits participation students education, ultimately impacting diversity...

Corrosion of girder ends is a prevalent problem that significantly reduces the bearing capacity bridges. Current repair methods are expensive and difficult to implement. A novel method was developed for steel with corrosion damage using ultrahigh-performance concrete (UHPC) encase corrosion. For this repair, UHPC panels were attached girders shear studs welded web flange surrounding corroded area. This allowed forces transfer from panels. The provided new load path, thereby increasing...

Abstract Background Creativity is increasingly recognized as an important skill for success in the field of engineering, but most traditional, post‐secondary engineering education programs do not reward creative efforts. Failing to recognize creativity or efforts can have particularly negative effects those students with attention deficit hyperactivity disorder (ADHD), who may exhibit enhanced divergent thinking ability yet struggle traditional educational environment. Purpose/Hypothesis...

Introduction Despite efforts to increase the participation of marginalized students in Science, Technology, Engineering, and Mathematics (STEM), neurodivergent have remained underrepresented underserved STEM graduate programs. This qualitative study aims understanding experiences pursuing advanced degrees STEM. In this analysis, we consider how common school interface with invisibility neurological diversity, thus contributing a set unique challenges experienced by students. Materials...

The blast performance of concrete-filled fiber-reinforced polymer (FRP) tube (CFFT) bridge columns was studied through a two-phase study comprised and residual axial capacity experiments. Two one-fifth-scale CFFT two conventional RC having comparable flexural capacities were subjected to distinct levels explosive loading, causing damage but not complete failure. resilience the damaged quantified by measuring each column. exhibited superior strength ductility retention compared with columns....

While conventional fiber-reinforced polymer composites offer high strength and stiffness, they lack ductility the ability to absorb energy before failure. This work investigates hybrid fiber for structural applications comprised of polymer, steel fiber, glass fibers address this shortcoming. Varying volume fractions thin, ductile were introduced into reinforced epoxy composites. Non-hybrid composite specimens prepared subjected monolithic half-cyclic tensile testing obtain stress-strain...

We propose a conceptual framework that integrates awareness into Relational Quantum Dynamics (RQD) by reinterpreting quantum interactions as intrinsic acts of awareness. Drawing on insights from physics, idealist philosophies, and information theory, our posits consciousness is the fundamental substrate being, with emerging through relational updating between interacting systems. operationalize realization event-quantified measures such mutual integrated metric (Φ) Integrated Information...

This paper presents Relational Quantum Dynamics (RQD), a paradigm that re-envisions quantum theory and its interplay with spacetime, observers, consciousness. Abandoning the notion of preexisting universe or fixed manifold, RQD posits observed systems, geometric structures emerge together as stable relational patterns in an underlying substrate. Spacetime is thus recast effective, large-scale feature entanglement information flows rather than fundamental stage. By eliminating pre-given...

Relational Quantum Dynamics (RQD) is a relational interpretation of quantum theory that rejects any absolute, observer-independent properties. We present rigorous mathematical formulation RQD’s account Bell’s inequality violations, using category and sheaf to formalize contextuality. In this framework, measurement outcomes form presheaf over contexts, i.e., sets jointly measurable observables, the impossibility global hidden-variable assignment interpreted as absence section presheaf....

We propose a novel framework that formalizes awareness within Relational Quantum Dynamics (RQD) by integrating Integrated Information Theory (IIT) with quantum measurement processes. In our approach, interactions are not merely stochastic events, but interpreted as intrinsic updates occur via Bayesian conditioning. Specifically, we define an metric A(A : B) combines the mutual information generated during interaction and Φ measure of integrated information. By modeling measurements processes...

We present a mathematically rigorous derivation of the Born rule within framework Relational Quantum Dynamics (RQD), an interpretation quantum mechanics emphasizing role observers and their relations. RQD postulates that states are observer-dependent observer’s awareness measurement outcomes is fundamentally classical. formalize these ideas by defining Category Awareness as classical probability space, Markov category, constructing functor F maps to distributions over observer. Under minimal...

Relational Quantum Dynamics (RQD) provides a category-theoretic relational interpretation of quantum mechanics, treating interactions as intrinsically observer-dependent. This paper extends RQD’s categorical framework by incorporating enriched and higher-category structures to capture quantitative information metrics multi-agent relationality. We introduce an category formulation RQD in which the functorial mapping F : Q → A (from physical processes awareness updates) carries information-...

We develop an extended formulation of Relational Quantum Dynamics (RQD) in which the quantum wave function is treated as intrinsic relational entity rather than external absolute state. Building on enriched category theory and related advanced frameworks, we formalize RQD using higher-category structures presheaf/topos-theoretic tools to rigorously capture web relations between systems (observers observed). In this formalism, each pair associated with a Hilbert space state vector, morphisms...

We establish a rigorous connection between Relational Quantum Dynamics (RQD) and Categorical Mechanics (CQM) by formally showing that the category Q of quantum processes in RQD can be endowed with structure dagger compact category. In particular, we demonstrate satisfies axioms symmetric monoidal closure, mirroring standard categorical formalism for theory. Within this framework, key physical features mechanics, such as transfer awareness (information) interactions, no-cloning theorem,...

We propose a rigorous synthesis of the ancient Indra’s Net metaphor with Relational Quantum Dynamics (RQD), casting quantum reality as web relationships formalized in category-theoretic and information-theoretic terms.
