A note on non-minimal abelian codes
No full textIn this paper, we compute the minimum weight of some particular non-cyclic codes which is a direct sum of two minimal codes. Then we show that these non-cyclic abelian codes of length pn, where p is a prime number, are more convenient than any cyclic code of the same length where n≥2. This generalizes a result of Polcino Milies and de Melo which compares the convenience of the non-cyclic abelian and cyclic codes of length p2. © Instituto de Matemática e Estatística da Universidade de São Paulo 2025
How Istanbul's youth reproduce a differential space
No full textMaçka Democracy Park is a notable public space for Istanbul’s youth, attractinga diverse group with varied social backgrounds. The activities and lifestylesobserved here might initially seem to reflect Turkey’s political tensionbetween conservatism/religiosity and secularism/Westernism. However,youth’s use of the park suggests that they envision urban spaces beyondthese traditional dichotomies. Parks provide a ‘differential space’ for youngpeople, women, and the LGBT+ community, supporting ‘the right todifference’ through daily activities. This study examines young people’smotivations for using parks and how they transform the park into adifferential space through interactions with various social groups andinstitutions
Wood-waste classification using interpretable machine learning
No full textDetermining and classifying the contents of wood wastes, which possess an extremely heterogeneous structure, is crucial for their optimal utilization. The heterogeneous nature of waste wood poses significant challenges for its separation and classification. Also, the classical chemometric methods are not ergonomic in terms of time and cost. For this reason, this study aimed to develop an efficient ML-based decision support system (DSS) for accurate classification of waste wood in addition to being an ergonomic approach versus chemometric methods. To develop ML-based DSS, firstly absorbance values at 650–4000 cm−1 wavelength were measured using FTIR-ATR device for 200 wood-waste samples. Absorbance values at 52 key wavelengths, identified as the most effective for characterizing the samples, were used as input features to estimate ML classification models using artificial neural networks (ANN), random forest (RF), ensemble learning, multiple logistic regression (MLR), discriminant analysis, Naive Bayes, K-nearest neighbour (KNN), and support vector machines (SVM). The analysis results indicated that the developed DSS achieved quite a high classification accuracy rates, approaching 100%. As a result, this kind of ML-based DSS can be used as a practical and efficient tool to determine and classify the contents of wood wastes. © 2025 Informa UK Limited, trading as Taylor & Francis Group
Assessing the role of SiPM number on energy resolution in radiation detection using bismuth germanate crystals
No full textIn this study, we present a simple statistical model to show the relationship between the number of Silicon Photomultipliers (SiPMs) and the energy resolution of the detector. We used bismuth germanate (BGO) crystals in combination with varying numbers of SiPMs to examine the effect of photodetector count on energy resolution. We compared our results with Photomultiplier Tube-based measurements to determine the advantage of SiPMs in terms of energy resolution. We also performed a simulation study with the GEANT4 simulation package to investigate the energy resolution that can be achieved under ideal conditions by using a higher number of SiPMs. The experimental measurements showed that for a photopeak energy of 511 keV, an energy resolution of 29.9% was achieved using five SiPMs covering only 3.25% of the scintillator area, whereas a Photomultiplier Tube (PMT) covering 37% of the same area resulted in an energy resolution of about 23.4%. As a result of the simulation study, it is predicted that the energy resolution can be achieved up to 14.8% for a photopeak energy of 511 keV by using 21 symmetrically distributed SiPM. © 2025 Elsevier Lt
Enhancing Earthquake Resilience of Historical Monuments: A Comparative Study for the 2023 Kahramanmaras Earthquake
No full textHistorical structures, integral to a city’s cultural fabric, embody architectural, artistic, and social history. Their preservation honors the past and ensures future generations appreciate their significance. In many old cities, tourism thrives due to historical buildings, monuments, and sites, which contribute significantly to local economies and job creation. Resilient structures, capable of withstanding natural disasters, remain vital for tourism. However, historical structures face vulnerability to earthquakes, floods, and other hazards due to aging materials and construction techniques. Assessing their resilience is essential to identify risks and implement mitigation measures. Beyond their physical form, these structures are woven into communities, providing continuity and stability. Our study focuses on three historical structures in major cities affected by the 2023 Kahramanmaras earthquakes. We emphasize proactive resilience reviews from an earthquake performance perspective. Brief histories and earthquake performances under poor, median, and good conditions underscore the importance of rehabilitation and restoration efforts

Lâle ve Cengiz Akıncı Koleksiyonu'nun İstanbul Resim Heykel Müzesi'ne bağışı, kurumun tarihindeki en önemli aşamalardan birini temsil ediyor. Kurumsal belleği, üzücü bir biçimde, neredeyse devamlı denebilecek bir açılma-kapanma hareketiyle belirlenmiş olan İRHM'nin 2007'deki kapanışı, Müze'nin 1937'de içine doğduğu, kök saldığı ve yuvası saydığı Dolmabahçe Sarayı'nın Veliaht Dairesi'nden 2011'de çıkarılması gibi beklenmedik bir sonuç doğurmuştu. Şimdi Müze, bir defa daha açılıp kapanmakla kalmıyor, tarihsel meskeninden de ayrılıyordu. Bu bakımdan bu defaki kapanma, kurumun tarihindeki diğer kapanmalara pek benzemiyordu ve açıkçası, Müze'nin yakın bir zamanda yeniden açılacağına dair ümitler fazla değildi. Bu durum, temelde sanatla bağlantılı eğitimler üzerinde yoğunlaşan MSGSÜ'nin Sanat Tarihi Bölümü'yle, Güzel Sanatlar Fakültesi ve Mimarlık Fakültesi'ne bağlı bölümlerinin öğrencileri için olumsuz bir tablo demekti: zira Müze'nin, okuldaki eğitimi bütünleyen bir kurum olarak taşıdığı yaşamsal önem ortadaydı. Müze, daima Güzel Sanatlar Akademisi'nin bu halef kurumu olan MSGSÜ'nin bölümlerini beslemiş, onların bu kurumun temel amacı olan sanat bilgisiyle donanmasında önemli bir araç görevi görmüştü. ..

Urban scale holistic physical risk assessment model based on multi-hazard types
No full textKentsel yerleşme bütününde çoklu tehdit türlerine bağlı olarak değişkenlik gösterebilecek zarar görme durumlarını tanımlayan bütüncül risk değerlendirme modeli ile kent bütününde öncelikli iyileştirilmesi gereken konuları ve bu konuların mekânsal dağılımını tanımlamak amaçlanmaktadır. Makalede modelin fiziksel risk değerlendirme aşaması anlatılmaktadır. Modelde deprem, sel/taşkın/su baskını, heyelan, gibi yersel etkili doğal olaylar ile iklimsel özelliklerin bir arada değerlendirilmesi ön plana çıkmaktadır. Modelde tanımlanan kriterler ve ağırlıkları literatür taraması sonucu ikili karşılaştırma yöntemi ile tespit edilmiş olup, maruz kalma, zarar görebilirlik ve risk haritaları ağırlıklı toplam modeli ile coğrafi bilgi sistemleri aracılığı ile üretilmektedir.
Örnek alan Kırklareli Merkez ilçesidir. Risk büyüklüğü 1 en az 5 en çok olarak sınıflandırılmıştır. Sonuç olarak Kırklareli Merkez ilçesi fiziksel risk dağılımı haritaları her bir tehdit türüne göre ayrı ayrı üretilmiş ve ağırlıklı toplama göre bir araya getirilerek çoklu tehdide bağlı risk tanımı yapılmıştır. Buna göre Merkez ilçe yerleşmesinin yaklaşık %80’i orta riskli ve %2.85’i dördüncü seviye olan riskli alan olarak tespit edilmiştir.The holistic risk assessment model defines vulnerabilities that may vary depending on the type of hazard inthe urban settlement. This model aims to identify the priority issues that need improving across the entirecity and the spatial distribution of these issues. The paper describes the physical risk assessment phase of themodel. The model emphasizes evaluating natural events such as earthquakes, floods, landslides, and climatic events together. The pairwise comparison method through the literature review has defined the criteria andweights selected for the model, and the susceptibility, vulnerability, and risk mapping are made using aweighted sum model through geographic information systems. Risk size is assigned a numeric value from 1to 5, with 1 being the lowest. In conclusion, the paper provides physical risk distribution mapping ofK & imath;rklareli Central district, the study area, based on each hazard type. The paper also defines the multi-hazardrisk, combining maps with the weighted sum. Accordingly, the paper has demonstrated that approximately80% of the central district settlement is a medium-risk area, and 2.85% is a high-risk area.Kirklareli University Scientific Research Projects [KLUBAP-253]This research was developed by Kirklareli University Scientific Research Projects Coordination within the scope of the project titled KLUBAP-253 titled Method Discussion of Risk Communication for Social Resilience in the Context of Natural Disaster Risks
Planning social housing in 1960s Türkiye: policies, institutions, and projects
No full textThis article focuses on Türkiye in the 1960s because the process that beganwith the new constitution following the 1960 military coup constituted aturning point in Türkiye history, economic, political, social, and cultural. Theconcept of social housing also came to the fore for the first time duringthese years. This article examines the emergence and conceptualization ofsocial housing in 1960s Türkiye from a planning perspective. It situates thedevelopment of social housing within the broader framework of welfarestate policies and state-led planning practices shaped by the 1961Constitution and the Five-Year Development Plans. Particular attention isgiven to the role of the Real Estate Credit Bank as a key state institution infinancing and implementing housing schemes. Through an analysis ofselected housing projects, the article demonstrates how social housingpolicies were translated into architectural and spatial practices, and howthese projects reflected ownership-based models distinct from the rental-oriented systems common in Western Europe. By connecting policies,institutions, and projects, the study highlights the significance of the 1960sas a formative period in Türkiye’s housing history, when the planning ofsocial housing became closely intertwined with the construction of thewelfare state
The Legacy of Mesopotamia: A Transformation from Glazed Brick to Modern Art Practices
No full textMesopotamia, one of the oldest civilizations in human history, has had a profound influence on architectural and artistic practices. Glazed brick, a key material in this region, transitioned from load-bearing elements to vital components of aesthetic architecture1. The use of brick, particularly in Southern Mesopotamia, marked a significant development in construction techniques due to the scarcity of natural resources and the demands of settled life 2. The emergence of glazed brick enriched architectural aesthetics and ensured structural integrity, contributing to the visual identity of ancient cities such as Babylon
