From Physics To Environmental Policy : Exploring Boltzmann Distribution For Carbon Trading Permit Allocation, Ji-Won Park
NAKHARA (Journal of Environmental Design and Planning)
Combating climate change and reducing atmospheric CO2 emissions are imperative. While carbon trade, including taxes and trading systems, has been proposed, the allocation of initial permits is challenging. This study addresses this issue, exploring the application of the Boltzmann distribution for carbon emission permit allocation in carbon trading. The Boltzmann distribution method uniquely considers each country's environmental and economic contexts, assigning more responsibility to nations with larger populations and higher emissions, and providing incentives to lower-emission countries. This promotes fairness in global climate change efforts and influences national environmental policies. High-emission countries like China receive a high number of permits, …

Chiang Mai's Royal Crematorium: Siamese Influence Evident In Lanna Cremation Heritage, Sumavalee Chindapol, Piyadech Arkarapotiwong
NAKHARA (Journal of Environmental Design and Planning)
The Chao Luang crematorium was a temporary architecture made for the cremation and funeral of Chao Luang Chiang Mai (King of Chiang Mai). The creation of the Chao Luang crematorium reflected the social and political pressures of Siam that influenced Lanna territories during the reign of Phra Chao Inthawichayanon in 1873 till 1932 (coup d’etat), resulting in a change in the architectural style of these funeral structures. This research aims to study the architectural style changes of Chao Luang crematorium in Chiang Mai from the moment when Siam began to draw power from Lanna to the central part of the …

NAKHARA (Journal of Environmental Design and Planning)
The establishment of the value and effective protection of historical ruins comprises a subject of rising interest, as evidenced by an increasing amount of research involving several disciplines. In Bangladesh, debates on the relevance of such abandoned, degraded, deformed, or empty structures—unlike other intact monuments in heritage studies—rarely take into account the attitude of the locals towards these ruins. Analyzing the case of Dinajpur Rajbari, Bangladesh, the paper intends to explore the value ascribed to historic ruins by the surrounding community. The study uses a case study approach built on Mason’s value typology, which has widely contributed to the identification …

The Effect Of Lighting In Higher Education Classrooms On College Students, Caitlin M. Nelms
Honors College Theses
Classroom lighting design is important for student learning outcomes, and can have a negative effect on the physiological states of students. Interior lighting design needs to include appropriate layers of artificial and daylighting. Previous models have shown that artificial lighting can be altered to give off the same effect of natural daylight. Studies have also shown that natural lighting has a positive effect on the productivity of students in a classroom environment. Data was collected by surveying students in a classroom with no natural lighting to see how they felt in the room and if they have any lighting recommendations …

Mansoura Engineering Journal
Circular concrete-filled steel tubular (CCFST) columns are widely utilized in structural engineering due to their impressive load-bearing capabilities and ductility. Existing design standards often yield disparate outcomes when applied to structural columns with identical properties, introducing uncertainty for engineering designers. This study introduces an innovative technique to address these challenges using two machine learning (ML) models: Gaussian process regression (GPR) and extreme gradient boosting (XGBoost). These models consider various input variables, including the geometric and material properties of CCFST columns, to estimate the compressive strength. The models undergo training and evaluation using two datasets comprising 1004 axially loaded CCFST columns …

Due to the lack of solar energy continuity throughout the day, researchers tended to store this energy in phase change materials (PCM). The goal is to store a big amount of energy in a small PCM mass. In this study, the effect of the capsule shape (circular and elliptical cross-section), number of capsules with the same volume (1, 2, 3, 4, and 5 capsules), and one capsule with increasing its initial volume (multiplying of volume ratio 1 (Vr = 2, 3, 4, and 5)) on the PCM melting process was studied. The results of the numerical model for both circular …

A Novel Method For The Production Of Pig Iron In “Hadisolb” Company (Industrial-Scale Experiments), El-Sayed A. Rassoul
Mansoura Engineering Journal
The chairman of “Hadisolb” had submitted a memorandum in 1977 in which he claimed that the company will never achieve its designed capacity unless it gets rid of the threatening impurities -high alkalis & MnO- in the blast furnace burden. Meanwhile, the DR steel companies are suffering from the generated accumulated wastes which contain > 67% Fe, zero% alkalis and traces of MnO. The novel idea here is finding the best ratio between El-Gedida ore and the waste material (W.M.). In a previous investigation a series of pilot-scale sintering experiments were performed and it was concluded that the blend containing 70% …

Mansoura Engineering Journal
The purpose of this research is to investigate the impact of hybrid micro and macro polypropylene fibers (PPFs) on the mechanical characteristics and microstructure of high performance concrete (HPC). Seven concrete mixes with different contents of hybrid polypropylene fibers were tested. The tests included the slump test, compressive and flexural strength, resistance to elevated temperatures, and concrete microstructure. Compared to the control mixture, introducing macro and micro polypropylene hybrid fibers to HPC mixes dramatically enhanced the flexural and compressive strength of concrete while lowering workability. HPC compressive and flexural strengths decrease as temperature rises, nevertheless, the strength loss rate was …

The anatomy of the retinal fundus picture, which includes the optic disc, affects how glaucoma characteristics are extracted. One of the main causes of blindness in the globe is glaucoma. Correct glaucoma screening in its early phases is difficult since the condition only becomes apparent when its symptoms are severe. If glaucoma is not treated, the optic nerve head (ONH) will be harmed, resulting in vision loss. Nevertheless, there are currently not enough eye experts accessible, and eye screening is personal, time-consuming and labor-intensive. Therefore, this is a real issue that can be addressed by automatically diagnosing glaucoma using deep …
