    Some Geometric Properties of the Duals of Cesàro Sequence Spaces
    (Walter de Gruyter GmbH, 2025) GÖNÜLLÜ, UĞUR
    The spaces d(s) are defined for 0 <= s <= infinity. We consider the fundamental geometric properties of the d(s) spaces, isomorphic duals of the Cesaro sequence spaces ces(r) with 1/s + 1/r =1. We prove that for 1 <= s < infinity, the Banach spaces d(s) are Radon-Riesz spaces that are not rotund or smooth. Moreover, we show that the Banach lattice d(1) has Schur's property, just as i1 does. Finally, a characterization of norm totally bounded subsets of d(1) is also given.

    Algorithmic Replication of Macramé Techniques: Bridging Analog Movements With Computational Design
    (Emerald Publishing, 2025) ÇEVİK, AYŞE NESLİGÜL; Açıkgöz, Ece Kumkale
    PurposeThis study explores how traditional macram & eacute; techniques can be digitally controlled and automated, contributing to the preservation of cultural heritage and offering a new perspective for innovative architectural applications. By translating macram & eacute;'s knot-making process into a computational model, this research aims to protect traditional know-how and transfer it to future generations while addressing modern design challenges related to adaptive, sustainable building solutions.Design/methodology/approachThe research involves a review of literature on the geometric and mechanical analysis of macram & eacute; weaving, focusing on knot tightness, yarn thickness and the resulting structural rigidity, as well as their digital counterparts. By using Rhino/Grasshopper, the study develops an adaptable digital macram & eacute; model capable of mimicking analog knot-making movements. In addition, two parametric variations (tight vs. loose knots) were tested as daylight-control systems through digital simulation. Luminance data were analyzed using ImageJ, incorporating brightness histograms and false-color heatmaps to assess performance.FindingsThe study demonstrates that digital simulations of macram & eacute; movements can enhance both the precision of production and its adaptability to architectural applications such as shading and airflow modulation. The luminance analysis indicates a substantial variation in daylight performance based on knot tightness. However, the current parametric script is limited in its adaptability to 3D geometries due to coordinate system constraints, which are discussed as a key area for future development.Originality/valueThis research advances the field of digital-analog integration by developing an algorithm that not only replicates traditional macram & eacute; movements but also tests their performance in a building context. By digitally preserving cultural knowledge and applying it in adaptive fa & ccedil;ade systems, the study aligns with SDG 11 (Sustainable Cities and Communities) and SDG 9 (Industry, Innovation and Infrastructure), demonstrating how traditional crafts can inform sustainable and responsive architectural solutions.

    Relationship Between Colours and Emotions as Reflected in Children's Drawings
    (John Wiley and Sons Ltd, 2025) AYDOS, EMİNE HANDE; Özet, Bahar
    Children articulate their emotions and experiences through drawings and the colours they incorporate into them. This study investigated the relationship between preschool children's colour preferences, the emotions those colours elicit, and how they convey their emotions and thoughts through drawings. The participants, comprising 30 children (19 girls and 11 boys) in Istanbul, were prompted to select a colour card that best represented their feelings and draw a visual representation of their current emotions. Most children linked a single emotion to a specific colour, whereas others demonstrated more intricate emotional representations by associating multiple emotions with one colour. Colour-emotion associations were highly individualised, although some general patterns were observed, and this showcased individual variability shaped by experiences, interactions, and environmental influences. Their drawings predominantly portrayed positive emotions related to family interactions, friendships, and pleasurable activities. Negative emotions were associated with loss, separation, or challenges. These results emphasise the importance of integrating art-based activities into early childhood education to support emotional literacy and communication.
