Posthuman Architecture And The Machine: A Theoretical Approach To The Impacts Of Artificial Intelligence On Architecture, Waleed Joudah Nassar Alsaadi, Ibrahim Jawad Kadhim Al-Yousif
Iraqi Journal of Architecture and Planning
Posthumanist philosophy shifts the focus away from independent, human-centred thinking toward diverse, pluralistic modes of knowledge. It adopts the idea that human agency is interconnected with a broad network of other actors, such as contemporary intelligent machines, most prominently embodied in artificial intelligence. This research discusses the relationship and interconnection between architecture in its posthuman form and technology, selecting artificial intelligence as a model of this technology, as it represents the most significant technical and intellectual revolution at present. The study examines posthumanism as a radical theoretical model that seeks to transcend the limitations of human thought and anthropocentrism. The …
Conceptual And Formal Levels In The Digital Computational Architectural Design Process, Maysaa Izyara Mohammed, Amjad Mahmoud Albadry
Conceptual And Formal Levels In The Digital Computational Architectural Design Process, Maysaa Izyara Mohammed, Amjad Mahmoud Albadry
Iraqi Journal of Architecture and Planning
This research examines the evolution of digital-computational design in architecture, from early Computer-Aided Architectural Design (CAAD) to contemporary practices. It distinguishes between digital design (DD), which treats digital tools as drawing instruments, and computational design (CD), which employs algorithms for deduction, induction, and abstraction. Three levels of design are identified: the Formation Level (pre-conceived forms), the Generation Level (emergent forms without preconception), and the Evolutionary Level (nature-inspired, performance-optimised forms). A critical threshold is explored where design transcends representation, embracing dynamic, algorithmic, and data-driven processes. Using analytical frameworks, literature reviews, and case studies of firms such as Gehry Partners and Zaha …

Interpretable Machine Learning Of Plasma Proteomics Reveals Stage-Specific Signatures Across The Alzheimer's Disease Continuum, Hemshankar Laugi
Interpretable Machine Learning Of Plasma Proteomics Reveals Stage-Specific Signatures Across The Alzheimer's Disease Continuum, Hemshankar Laugi
2026 Spring Honors Capstones Projects
Alzheimer’s pathology begins years before clinical symptoms, starting early with amyloid-β accumulation, followed by tau deposition and neurodegeneration. Although existing tools, such as cerebrospinal fluid (CSF) screening and PET/MRI imaging, can accurately track disease progression, they are invasive, expensive, and not scalable for population-level screening. So, there is a growing interest in using blood-based plasma biomarkers as a scalable alternative. While recent studies demonstrate strong predictive performance with plasma biomarkers, most rely on a small set of canonical blood-based protein biomarkers such as amyloid-β, p-tau, and neurofilament light. These biomarkers primarily reflect downstream brain pathology and may fail to capture …

Global education monitoring
Sustainable Development Goal (SDG) 4 aims to ensure that, by 2030, “all girls and boys complete free, equitable and quality primary and secondary education leading to relevant and effective learning outcomes.” The primary indicator 4.1.1 concerns the proficiency of girls and boys in two learning areas (reading and mathematics) at three stages of education: at the end of lower primary, at the end of primary, and at the end of lower secondary. Large-scale learning assessments are essential tools to capture data on learning outcomes and to provide system-level evidence on education quality and equity. In the context of SDG 4, …

How Preservice Teachers' Confidence Is Impacted By A Geometry Course, Stephanie Hastings, Gabriel T. Matney
School of Inclusive Teacher Education Faculty Publications
A large body of literature supports the notion that a K-12 teacher's confidence in teaching and content impacts student achievement. This study explores a group of preservice teachers and their confidence in teaching geometric concepts. The eight participants were preservice secondary mathematics teachers enrolled in a high-school-focused geometry course centered on pedagogical content knowledge. Using mixed methods, the study examined how their confidence to teach geometric topics changed over the course, with participants rating that confidence on a 4-point Likert scale. Confidence to teach most topics increased significantly. Six themes emerged from the second round of interviews: (1) deep understanding …

Journal of System Simulation
Abstract: In view of the difficulties in dynamic reconfiguration and resilience evaluation faced by modern combat system-of-systems in a highly adversarial environment, and the deficiencies of existing studies in depicting high-order interaction relationships and cluster evolution mechanisms, this paper proposed a resilience modeling method for combat system-of-systems integrating hypernetwork and game theory, aiming to analyze the resilience mechanism of the system-of-systems in all dimensions from micro, mesoscopic, to macro levels.

Evolution And Prospects Of Polarization Image Simulation Technology, Gengpeng Li, Wei Cai, Zhiyong Yang, Zhili Zhang, Xiaowei Wang
Journal of System Simulation
Abstract: Polarization image simulation technology is a key means to break through the bottleneck of polarization data acquisition and promote the development of polarization vision. This study systematically reviewed three evolutionary paradigms of this technology: Physical mechanism simulation, based on the polarization bidirectional reflectance distribution function and polarization ray tracing, strictly solves polarization light transmission, which has high interpretability and credibility, but it is computationally complex and lacks visual realism. Data-driven simulation, using models like neural radiance fields to learn polarization appearance from data, has high generation efficiency and visual fidelity but weaker physical consistency and interpretability. Physics-data fusion simulation …

Leveraging the characteristics of multiple routes, the overall cooperative control problem of the swarm was decoupled into the cooperative control within the same route and the consensus control between multiple routes. Within the same route, a forward-neighbor information interaction mechanism was designed to determine the neighbor relationships, and a velocity-guided cooperative algorithm was utilized to achieve the desired velocity matching and spacing maintenance of unmanned aerial vehicles; between multiple …
