The Felt City : Sensory–Cognitive Mapping Of Urban Atmospheres In Izmir, Turkey, Çağla Duygu Üstün, Fatma Ipek Ek

NAKHARA (Journal of Environmental Design and Planning)

This study investigates the multi-sensory atmospheric qualities of two pedestrian corridors in İzmir, Turkey—Kıbrıs Şehitleri Avenue and Bornova Street—and examines how sensory input interacts with emotional and cognitive processes in shaping urban experience. Using a mixed-methods approach, the research combines an online questionnaire (n = 120) for case selection with in-situ aesthetic fieldwork based on guided walks and semi-structured elicitation (n = 20). The analytical framework is based on Böhme’s concept of atmosphere generators and is further extended through the notion of moodmosphere to capture cognitive–affective interpretations such as memory, attachment, and personal associations. Within this framework, the felt city …

Interchangeable Sensorial Encounters With Nature In Older Adults’ Domestic Space In Indonesia, Paramita Atmodiwirjo, Ruth Kartika Purnasasmita, Paramita Atmodiwirjo, Yandi Andri Yatmo, Demet Dincer

NAKHARA (Journal of Environmental Design and Planning)

This study investigates how older individuals encounter nature through sensorial contact in their domestic settings. It argues that nature should be integrated into the older adults’ domestic spaces to foster connections with nature that promote active living and improve their well-being. Such interactions with nature are captured by understanding the relationships between the degrees of connection with nature: viewing nature, being in nature, and doing in nature. This study was conducted through field observations and interviews with 24 older adults with varying physical capacities and levels of independence across 15 households in Jakarta and West Java.

Integrating Bangkok’S Western Canals For Micro-Mobility And Last-Mile Connectivity : A Spatial Analysis Of Man-Powered Paddle-Boat Movement, Sasima Chaichulee, Puntra Amphan, Parthorn Satitanon, Pasinee Jongraktanakit, Patiphol Yodsurang

NAKHARA (Journal of Environmental Design and Planning)

This study presents an intentionally extreme analytical scenario to expose gaps in urban mobility planning by evaluating the potential of Bangkok’s western canal system to function as vernacular micro-mobility infrastructure for last-mile connectivity. The research provides the first empirical survey of canal-based mobility conducted using self-owned, man-powered paddle boats operated by local residents, generating primary data on everyday waterborne movement. Using geotagged field surveys and GIS-based spatial analysis, the study maps boat activity, access landings, navigability constraints, and connectivity to public transport. The results reveal concentrated corridors of active vernacular mobility alongside extensive segments constrained by sedimentation, fragmented hydrology, and …


Green Project Finance For Infrastructure And Building Construction: Instruments And Benchmarks, Yunping Liang Jan 2025

Green Project Finance For Infrastructure And Building Construction: Instruments And Benchmarks, Yunping Liang

Durham School of Architectural Engineering and Construction: Faculty Publications

It is counterintuitive that both the practice and research on green project finance for infrastructure and building construction are ascendant and still have limited precedents, considering that individually, the two parts (i.e., project finance and sustainability in the built environment) are both familiar to the communities. To narrow the gap and facilitate the financing of the built environment’s sustainable transformation, this study systematically reviews the common instruments for financing green infrastructure and building projects. Benchmarking questions distinguishing the profile of green project finance from common construction project finance are developed based on the literature review and then are used for …


Ultrabaroque Grandeur: Examining The Churrigueresque In Spanish Architecture From The Seventeenth And Eighteenth Centuries, Sarah Staeben Jan 2025

Ultrabaroque Grandeur: Examining The Churrigueresque In Spanish Architecture From The Seventeenth And Eighteenth Centuries, Sarah Staeben

Capstone Showcase

Following the Protestant Reformation, Spain was in a unique position compared to the rest of Europe. The importance of Catholicism was intrinsic to Spanish society by this point, as it was under King Ferdinand and Queen Isabella, aptly dubbed the Catholic Monarchs, that the Christians reconquered the Iberian peninsula in 1492, after an eight century rule by Arab-Muslims. In the centuries that followed, Spanish architecture reached new levels of grandeur in the wake of reformed Catholic doctrine. Following the motto “docere, delectare, movere”(to teach, to delight, to move), architects were urged to convey the Church’s power and garner new supporters. …

Business Model Evaluation Of Renewable Energy Community In Multi Unit Residential Building In Canada Net Metering, Considering The Regulatory Framework, Ownership And Organizational Structure, Zahra Keshavarz Moraveji, Yunping Liang, Ursula Eicker

Durham School of Architectural Engineering and Construction: Faculty Publications

Renewable Energy Community (REC) is an emerging concept that empowers local customers to generate decentralized renewable energy. Integrating RECs into the building industry presents a promising opportunity to support the transition toward net-zero cities. However, the viability of RECs depends on regional regulatory frameworks, permitted governance structures, and very importantly, business models. Compared to pioneering European countries, Canada lacks the regulatory support needed to fully enable REC. This paper proposes and evaluates various business models for potential REC implementations under Canada's existing regulatory constraints. The analyzed models focus on "behind-the-meter" electricity distribution, a multi-stakeholder type of REC, where generation occurs …

Optimized Vgg16 For Multi-Class Classification Of Alzheimer's Disease, Amira M. Basuoni, Hussein Seleem, Amira S. Ashour

Mansoura Engineering Journal

Alzheimer’s disease (AD) is a severe neurological disorder that leads to memory loss and other cognitive impairments, ultimately resulting in death. With the advancement of deep learning, several researchers implemented a deep learning (DL)-based classification system for diagnosing such disease. However, determining the proper setting of the parameters, like learning rate and the number of dense units in the classification model is essential to achieve the best performance. Although manual tuning and grid search methods may be used, they are often time-consuming and cannot achieve the optimal model’s design. Accordingly, this paper proposed an improved model of the Visual Geometry …


Adaptive Watermarking Scheme For Enhanced Image Authentication And Restoration, Merna E. Ibrahim, Mohamed G. Abdelfattah, Mohamed A. Mohamed Jan 2025

Adaptive Watermarking Scheme For Enhanced Image Authentication And Restoration, Merna E. Ibrahim, Mohamed G. Abdelfattah, Mohamed A. Mohamed

Mansoura Engineering Journal

Traditional fragile watermarking schemes often struggle to balance tamper detection accuracy, image quality, and processing speed. This paper presents a novel adaptive fragile watermarking scheme that leverages Canny-edge detection to dynamically adjust watermark embedding based on image features. The proposed approach classifies image regions into smooth and dense areas. Larger 4×4 blocks are employed in smooth regions, prioritizing visual quality and processing speed, while smaller 2×2 blocks are used in edge and dense regions to enhance tamper detection accuracy. This adaptive strategy effectively balances competing factors, resulting in superior recovered image quality compared to fixed-block schemes. Experimental results demonstrate the …

Non-Line-Of-Sight Classification In Urban Areas Based On Machine Learning Algorithms, Mohamed Ali Ezzelarab, Mohamed Abdelazim Mohamed, Eman Abdelhalim, Ashraf Abosekeen

Mansoura Engineering Journal

Non-Line-Of-Sight (NLOS) and multipath errors are significant causes of poor accuracy in Global Navigation Satellite Systems (GNSS). These errors occur when satellite signals are diffracted or reflected by obstacles instead of traveling directly along the Line-Of-Sight (LOS), particularly in urban environments. Such diffracted or reflected signals can reach GNSS receivers, skewing pseudorange measurements and posing challenges to accurate GNSS positioning. This study introduces an innovative approach using supervised Machine Learning (ML) models to detect and mitigate NLOS error. To develop and validate these models, GNSS data collected during the smartLoc project from Frankfurt and Berlin in Germany were leveraged, representing …
