Cinematic Architecture: Perceiving The Real From The Reel In How To Make Millions Before Grandma Dies Film Setting, Edbert Theo Fortino
Chulalongkorn University Theses and Dissertations (Chula ETD)
Cinematic architecture is a multidisciplinary approach that examines the relationship between film and architecture. This thesis explores how film offers a unique way to immerse audiences in spatial experience. Through time, movement, and visual framing, film can dramatize or reinterpret space according to the director’s vision, making it a valuable medium for understanding how architecture is perceived, used, and felt. Film also visualizes fragments of real everyday life, cultural practices, and spatial behaviour. Observing how characters inhabit and interact with spaces reveals how real users interpret the functional and symbolic meanings of architecture—insights often overlooked when architects rely solely on …

Experimental Investigation Of Surfactant Impact On Surfactant-Oil-Brine System For Surfactant Enhanced Oil Recovery, Chananpat Worpattanaluk
Chulalongkorn University Theses and Dissertations (Chula ETD)
Enhanced Oil Recovery (EOR) is a vital technique for improving hydrocarbon extraction efficiency from mature or low-production reservoirs. Among various EOR methods, chemical flooding, particularly surfactant-based EOR, has gained attention due to its ability to reduce interfacial tension (IFT), to alter rock wettability, and to mobilize trapped oil. However, the performance of surfactant systems is highly sensitive to reservoir salinity, temperature, and rock-fluid interactions, leading to surfactant precipitation, adsorption losses, and interfacial tension reduction. Therefore, understanding the effects of salinity, surfactant concentration, and the role of scale inhibitors on the physicochemical stability of surfactant-oil-brine systems is essential for designing robust …
Pipeline For Non-Self-Intersecting Racetrack Generation In Racing Games, Chatrtime Chatramornrat
Pipeline For Non-Self-Intersecting Racetrack Generation In Racing Games, Chatrtime Chatramornrat
Chulalongkorn University Theses and Dissertations (Chula ETD)
Procedural content generation (PCG) allows racing games to supply new racetracks automatically, but straightforward generators can produce layouts with unrealistically tight bends or self-crossings that compromise playability. This thesis introduces a racetrack generation pipeline that connects chain–code–based synthesis with a dedicated post-processing stage for resolving intersections. Candidate layouts are first assembled from image–based differential chain codes and adjusted so that each forms a closed loop. Regions where the centreline crosses itself are then identified and repaired by cutting and joining overlapping branches and applying locally constrained smoothing, so that the overall course geometry is kept intact. Finally, geometric descriptors such …

Out-Of-Domain Tuberculosis Detection From Chest X-Ray Images Using Meta Learning With Soft Labels, Kanokphat Jinanarong
Out-Of-Domain Tuberculosis Detection From Chest X-Ray Images Using Meta Learning With Soft Labels, Kanokphat Jinanarong
Chulalongkorn University Theses and Dissertations (Chula ETD)
Automated tuberculosis screening from chest x-ray images could greatly benefit regions with limited medical resources. However, currently available methods could not handle this problem well due to the difference in chest x-ray images in each region caused by the difference in machine and demographics, the possible noise in the available labels, and other reasons. We therefore propose a new machine learning algorithm that could detect tuberculosis with great accuracy on any other data sources by learning from completely different data sources. We used a model-agnostic meta-learning together with a soft label approach, utilizing the meta-gradient to dynamically adjust the soft …
