Energy-efficient thermal performance of walls and windows for four building orientations in four Indian climatic zones: A verified dynamic analysis of insulation, glazing type and glazing area

Facade design rules for Indian dwellings are still drawn largely from mid-latitude studies. This article presents a verified dynamic analysis of the thermal performance and energy requirements of external walls and windows for four orientations in New Delhi, Mumbai, Jaipur and Sh...

Solving Bi-objective Interval Assignment Problem using Trisectional Fuzzy Trapezoidal Approach

Background The conventional Assignment Problem (AP) may no longer be sufficient to handle real-world problems as they get more multifaceted and incorporate numerous, frequently conflicting objectives. In response, the Bi-Objective Assignment Problem (BOAP) provides an extended op...

Integrating K-means clustering with entropy-weighted TOPSIS for large-scale multi-criteria decision making

Multi-Criteria Decision Making (MCDM) methods like Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) consider all the alternatives at once, which can be computationally expensive and confusing as the problem size increases to hundreds or even thousands of...

First-Principles calculations to investigate structural, mechanical, electronic, optical and thermoelectric properties of RuNbAs and RuNbSb Half-Heusler alloys

This study presents a first-principles investigation of the structural, thermodynamic, mechanical, electronic, optical and thermoelectric properties of RuNbZ (Z = As, Sb) half-Heusler (HH) alloys using density functional theory (DFT). Structural optimization, negative formation e...

Household electronic waste management practices and its determinants in Southwest Ethiopia: Analytical cross-sectional study

Electronic waste (e-waste) is a rapidly expanding environmental and public health global concern. 53.6 million tons of e-waste were generated globally in 2019.The generation of e-waste is increasing globally due to technological advancement, urbanization, and increased demand for...

Geographic variations and factors associated with breastfeeding counseling during the first 2 days of birth in Ethiopia: spatial and multilevel analysis

Breastfeeding improves child health, and counseling during pregnancy and after delivery supports early initiation and exclusive breastfeeding. However, coverage remains uneven in many low- and middle-income countries, and relatively little work has sought to use multilevel and sp...
