A Top-Down Hierarchical Approach for Automatic Indoor Segmentation and Connectivity Detection
Authors: Túñez-Alcalde Rosa M. , Albadri Muataz S. A. , González-Cabaleiro Patricia , Fernández Antonio , Díaz-Vilariño Lucía
Published: June 2024

Abstract. Data organization is essential for effective analysis of the spatial relationships between rooms and walls. Segmentation in successive stages plays a crucial role in this process since dividing the data set into smaller sets makes its analysis easier. The proposed approach starts with the segmentation of buildings by storeys using a three-dimensional point cloud and is carried out by detecting peaks in histogram of Z frequency. Subsequently, each storey is segmented into rooms using three-dimensional mathematical morphology techniques, which allows the delimitation of the interior spaces. The third and final step consists of identifying elements within each room, such as doors, ceiling, floor, and walls. During this process, connectivity and adjacency of building elements are studied to automatically derive topological graphs. This methodology results in a deeper and more systematic analysis of three-dimensional spaces, providing a solid basis for the subsequent interpretation and manipulation of the data obtained. The proposed method has been tested in two real cases and the results are shown respectively.
Towards a Deep Automatic Generation of Figure-ground Maps
Authors: Arzoumanidis Lukas , Hecht Jonathan , Dehbi Youness
Published: June 2024

Abstract. Figure-ground maps play a key role in many disciplines where urban planning or analysis is involved. In this context, the automatic generation of such maps with respect to certain requirements and constraints is an important task. This paper presents a first step towards a deep automatic generation of figure-ground maps where the built density of the generated scenes is controlled and taken into account. This is preformed building upon a Geographic Data Translation model which has been applied to generate less available geospatial features, e.g. building footprints, from more widely available geospatial data, e.g. street network data, using conditional Generative Adversarial Networks. A novel processing approach is introduced to incorporate the population density and the built density accordingly. Furthermore, the impact of both the level of detail of the street network, i.e. its sparsity or density, and the spatial resolution of the training data on the generated figure-ground maps has been investigated. The generated maps and the qualitative results reveal an obvious impact of these parameters on the layout of built and unbuilt areas. Our approach paves the way for the expansion of existing districts by figure-ground maps of future neighbourhoods considering factors such as density and further parameters which will be subject of future work.
Multi-Criteria GIS for Sponge City Planning with Open Data Sources in Vigo (Spain)
Authors: Balado Jesús , Solla Mercedes
Published: June 2024

Abstract. Sponge cities are renowned for their efficacy against extreme weather events, reducing surface runoff, managing stormwater, and mitigating flood risks. Moreover, they present multifaceted advantages by integrating blue-green infrastructure, enhancing urban sustainability, and improving water quality. The trend of their expansion beyond China marks a significant development in climate-resilient urban planning. This study pioneers the use of open data to locate suitable sites for sponge Low Impact Development (LID) solutions, showcasing Vigo (Spain) as a viable case for mid-sized cities. Input data is obtained from administrative cartography (DTM, hydrogeology, land cover, river courses, and demographic census) and satellite imagery (impervious coverage, vegetation, and surface temperature) from Landsat 8 and MODIS calculating three spectral indices (NISI, NDVI, NDIH). A robust Geographical Information System (GIS) method is proposed weighting the multi-criteria with AHP matrix. Three main potential sites are identified for deploying specific sponge LID strategies, as green roofs, green parking, or rain gardens. Nevertheless, while the method swiftly identifies intervention sites on a municipal scale, conclusive decisions necessitate terrain insights, public sentiments, urban regulations, and funding considerations.
Integrated approach to improve Road Infrastructure Resilience through complementary Non-Destructive Techniques
Authors: Alonso-Díaz Alex , Solla Mercedes , Rodríguez Juan Luis , Elseicy Ahmed
Published: June 2024

Abstract. Transportation infrastructure serves as the backbone of societal functionality. As aging road networks present increasing challenges, effective monitoring and maintenance become imperative. In this context, this article explores the integration of non-destructive techniques for monitoring and assessing damaged road sections. The work emphasizes the importance of leveraging the complementarity between non-destructive techniques to gain a holistic understanding of damaged road sections' structural integrity. Through the combination of these techniques, structural issues and underlying causes can be identified, as well as to develop maintenance and rehabilitation strategies.A case study of a critical section of the national road N-541 in Pontevedra, Spain, illustrates the application of this integration. First, Interferometry Synthetic Aperture Radar (InSAR) technology revealed points of interest. Four different cases, with two different methods: Scatterer Interferometry (PSI) and Quasi-PS (QPS) were used, to minimize uncertainty. Then, Global Positioning System (GPS) data, together with Laser Imaging Detection and Ranging (LiDAR), were used to create Digital Elevation Models (DEM). Finally, Ground Penetrating Radar (GPR) was useful to create a data cloud of possible subsurface damages. Machine learning technique (clustering) was applied to the GPR data to assist in defect depth analysis, further improving understanding and knowledge. The integration of complementary non-destructive methods offers a comprehensive framework for advancements in road infrastructure analysis and maintenance strategies, thus contributing to decision-makers to enhance transportation infrastructures' resilience and longevity.
Landslide and erosion processes in the high-mountain areas of the Greater Caucasus, Azerbaijan
Authors: Ildirim oglu Mardanov Ilham
Published: June 2024

This article presents the findings of ecogeomorphological studies conducted in the high-mountain belt of the southern slope of the Main Caucasus Range by utilizing satellite imagery. The investigations reaffirmed the dynamic nature of exogenous relief-forming processes evident in slope surface conditions and the diverse array of natural landscapes in high-mountain regions. The data acquired facilitated the development of measures aimed at enhancing the natural environment and guiding future land use practices. Through this research, various factors contributing to degradation processes were identified, enabling the pinpointing of erosion-prone areas on both slopes of the Greater Caucasus and the formulation of what we believe to be the most optimal anti-erosion measures scheme. Analysis of satellite imagery revealed that some river basins originating from the southern slope of the Main Caucasus Range exhibit the most pronounced soil and vegetation degradation processes.
Holocene environmental changes inferred from palaeobotanical data of Curonian Lagoon sediments
Authors: Sosnina Irina , Šeirienė Vaida , Grigienė Alma
Published: June 2024

Environmental development and water level changes in the south-western part of the Curonian Lagoon are reconstructed based on the results of bottom sediment investigations, including data on lithology, diatoms, pollen, and radiocarbon dating. Three stages have been identified in the ~ 10000-year history of the lagoon’s development. The diatoms suggest that in the Early Holocene, the southern part of the Curonian Lagoon was a shallow freshwater basin, mainly fed by run-off from the continent. During the Middle Holocene, the study area was a marshy coastal zone. Due to a change in hydrological conditions at the beginning of the Late Holocene, it became an open-water part of the lagoon.

Authors: Ramdhani Putri , Ansyari Pahmi , . Herliwati
Published: June 2024

Patin fish larvae have very small mouths, requiring natural feed at the early stages of larval rearing. This necessitates alternative rearing technologies without compromising the quality and quantity of the fry. The aim of this study is to determine if Black Soldier Fly Larvae can be used as a base material for pond preparation in Patin fish rearing. The materials used include 76 grams of Black Soldier Fly Larvae, placed in a bag according to the Indonesian national standard for fertilization in Patin fish rearing (200-500 grams/m2). The bag was then placed in a 38 cm diameter basin, which had been cleaned and filled with 20 cm of river water. During the 10-day rearing period, water quality (pH, temperature, and DO) was monitored, water changes were performed, and PF 0 feed was provided. After 10 days, the fry was harvested to measure their growth in length, weight, and survival rate. Black Soldier Fly Larvae or used maggot rearing media can be utilized as a fertilization medium in Patin fish fry rearing, as the growth parameters of the fry meet the Indonesian National Standards.

Financial law: searching answers to contemporary economic challenges
Authors: Vasyanina E. L.
Published: June 2024

The subject. Scientists face a serious task related to the formation of a modern model of financial law that will ensure the financial sovereignty of the state.

The purpose. The author attempts to form a modern approach to understanding the nature of financial law that meets economic challenges.

Methodology. The use of general logical research methods, including analysis and synthesis, the formal legal method.

Main results. The updated legal model of financial relations, aimed at creating a full-fledged mechanism of financial and legal regulation, can be formed by activating the process of convergence of private and public law, the development of which is justified by the tasks of legal technology. The rejection of the sectoral model of law, formed in the 1930s, in favor of the integrative structure of law allows us to consider financial law as a system of regulatory complexes that legally mediate the financial and credit mechanism of the national economy. The unifying basis for the formation of regulatory complexes covered by financial law are such key aspects as: the independent object and purpose of legal regulation of the relevant group of financial relations; the range of subjects of legal relations arising in the sphere of functioning of the financial and credit mechanism of the state; management tools used by the state and means used by participants in civil turnover to protect the right to dispose of finances.

Conclusions. The legal instruments that ensure the achievement of the goals of the functioning of the financial and credit mechanism of the contemporary state are: principles of public administration; administrative procedures, as well as the construction of a financial obligation.

VAREG-RUSLARIN BİZANS İMPARATORLUĞU İLE SİYASİ İLİŞKİLERİNİN BAŞLANGIÇ DÖNEMİ: 860 VE 907 KONSTANTİNOPOLİS SEFERLERİ
Authors: Samat Merve Cansu
Published: June 2024

Orta Çağ’da Rus olarak adlandırılan İsveç kökenli ulusun, IX. yüzyılın ortalarına doğru Rusya topraklarına yönelerek kuzeyden güneye bu coğrafyayı kademeli biçimde kolonize etmeleri, Rusya topraklarında yaşamakta olan Slav kökenli yerel halkı ve bölgeye sonradan göç etmiş olan Türk kökenli ulusları siyasi ve kültürel bağlamda etkisi altına alan bir göç hareketiydi. Bununla birlikte bu göç hareketini tetikleyen başlıca unsur, özellikle IX. yüzyılda ticari ilişkiler bakımından altın çağını yaşayan Hazar Devletiydi. Hazar Devletinin siyasi ve ticari organizasyonu başlangıçta Slavlara örnek teşkil ederek, Baltık bölgesine göç eden Doğu Slavları tarafından burada ticaret şehirleri meydana getirildi. Baltık’ın kuzeyinde yaşayan İsveçliler, ticarete olan ilgileri ve denizcilikteki yetenekleri dolayısı ile öncelikle Rusya’nın kuzeyine yağma akınları düzenlediler, ardından bu coğrafyanın kalıcı sakinleri ve yöneticileri haline geldiler. Rusların asıl amaçları kuzeyde bir imparatorluk kurmak değil, güneyde Hazar Devleti ve Bizans İmparatorluğunun hâkimiyetinde bulunan ticari rotalardan ve nehir yollarından faydalanmaktı. Bu nedenle Ruslar, zamanla Rusya’nın kuzeyinde, merkezini özellikle Novgorod ve çevresinin teşkil ettiği genç devletlerinin merkezini güneye, Kiev şehrine taşıyabilmek adına bir dizi girişimlerde bulundular. Kiev şehri, IX. ve X. yüzyıllarda kaynaklarının çokluğu ile değil, güneydeki ticarete ulaşımın bir istasyonu olarak Ruslar için büyük önem arz etmekteydi. Bu şehirde hâkimiyet sağlayan Rusların öncelikli amacı ise Konstantinopolis’e ulaşmaktı. Böylelikle Bizans’ın başşehri Konstantinopolis’in zenginliklerinden olabildiğince faydalanmak adına seferler düzenlediler ve bu seferler sonucunda bir takım ticari imtiyazlar elde ettiler. Rusların Bizans ile olan ilişkileri, 860 yılında Kiev’de bulunmakta olan Askold ve Dir isminde iki Rus kökenli boyarın Konstantinoplis’e yönelik bir yağma seferi düzenlemeleri ile başladı. Bu tarihten itibaren iki devlet arasında siyasi ve ticari ilişkiler, Rusların ganimet ve şöhret hırsı yahut Bizans hükümetinden elde etmek istediği imtiyazlar dairesinde şekillendi. Ancak Rusların bir devlet olarak Bizans tarafından tanınmaları ve diledikleri ticari imtiyazları elde edebilmeleri Knez Oleg döneminde mümkün oldu.
OSMANLI DEVLETİ'NDE İLİM EHLİNİN MENFİ FAALİYETLERİ (1595-1605)
Authors: Tamar İbrahim
Published: June 2024

Osmanlı’nın zaman içerisinde küçük bir beylikten dünyaya hükmeden bir imparatorluğa dönüşmesinde, ilim ehli kimselerin büyük etkisi yadsınamaz. Medreselerden yetişip önemli makamlara gelen ilim sahibi insanlar, devletin güç kazanmasında ve toplumun refah seviyesinin yükselmesinde daima önemli bir role sahip olmuşlardır. Nitekim kazanılan başarılar, bilimsel gelişmeler ve reayanın huzur seviyesi; şeyhülislam, kadı ve müderrislerin liyakatiyle doğrudan ilişkili bir durum olarak telakki edilebilir. Bu kimseler adaleti tesis etmeye çalıştıklarında, nitelikli insanlar yetiştirmek için canla başla uğraştıklarında ve sürekli kendilerini geliştirdiklerinde; Osmanlı topraklarındaki insanlar daha az sorun yaşamış ve devlet her geçen gün gücüne güç katmıştır. Ancak bu verimli sistem varlığını uzun süre devam ettirememiştir.
Bilhassa 16. yüzyılın ikinci yarısından itibaren medrese sisteminde tedricen bozulmalar başlamış, iltimas yaygınlaşmış ve kendi ihtirasları doğrultusunda hareket eden insan sayısı artış göstermiştir. Böylelikle devletin, zamanla eski gücünü kaybettiği ve toplumun da eski günlerdeki gibi huzur içerisinde yaşam sürmesinin zorlaşmaya başladığı söylenebilir. Bu durumun yaşanmasında ilmiye sınıfına mensup çok sayıda kimse baş rolde olmuştur. Birçok kadı, müderris ve suhtenin insanlara örnek olmak bir yana çok ağır suçlar işlediği kayıtlara geçmiştir. Bu kimselerin işlediği adam kayırma, cinayet, hırsızlık ve rüşvetçilik gibi daha birçok suç yalnızca kendilerine ve zulmedilen insanlara zarar vermemiş, aynı zamanda Osmanlı Devleti ve İslam dini kötü bir şekilde temsil edilmiştir. Bu sebeple ilim insanı olarak bilinen kişilerin menfi eylemlerinin açığa çıkarılması, hem Osmanlı devletinin belli dönemlerde yaşadığı buhranı anlayabilmek hem de İslam dininin emirlerinin dışına çıkıldığını görebilmek açısından oldukça önemlidir. Ele alınan bu çalışmada; 1595-1605 yılları arasında yaşamış olan ilim insanlarının olumsuz eylemleri incelenecektir. Söz konusu kimselerin gerçekleştirdiği olumsuz faaliyetlerin kaydedildiği mühimme defterleri, çalışmanın odak noktasını teşkil edecektir.

Для уравнений смешанного типа второго рода в неограниченных областях нелокальные краевые задачи в многомерном случае практически не исследованы.
С этой целью в данной работе в неограниченном параллелепипеде формулируется и изучается полу нелокальная краевая задача периодического типа для трехмерного уравнения смешанного типа второго рода второго порядка. Для доказательства единственности обобщённого решения используется метод интегралов энергии. Для доказательства существования обобщённого решения сначала используется преобразование Фурье и в результате получается новая задача на плоскости, а для разрешимости этой задачи используется методы "ε -регуляризации" и априорных оценок. Используя эти методы, и равенство Парсеваля, доказывается единственность, существование и гладкость обобщённого решения одной нелокальной краевой задачи периодического типа для трехмерного уравнения смешанного типа второго рода второго порядка.

Evaluation and Optimization of Basketball Tactics Training Effect in Physical Education: Application Research using Decision Tree (DT) Algorithm
Authors: Nan Hu
Published: June 2024

In this study, the decision tree (DT) technique is developed to assess the basketball strategies' training impact on physical education (PE). The recommended DT method effectively guesses the tactics of two teams based on the locations of basketball players with only a small amount of training data. Next, using data concerning ball possession, the interaction of these teams' tactics, and the distinctive features of basketball strategies, the DT approach changes the team's strategies.Therefore, effective findings from prediction could be produced because the suggested DT approach predicts the team strategies that meet these requirements. The suggested DT approach is implemented using the Python platform to analyze efficiency in terms of several metrics. Additionally, the DT method's effectiveness is contrasted with that of other approaches. Based on the results of the experiments, the suggested approach outperforms the current approaches in assessing the impact of basketball strategy instruction in physical education.

There is growing recognition that many adolescents obtain insufficient and/or poor quality sleep, which is regarded both as an epidemic of sleep deprivation amongst adolescents and an important public health problem. Adolescents are thought to optimally require approximately nine hours of sleep per night. However, a meta-analysis found that 53% obtain less than eight hours of sleep on school nights, and 36% report difficulty in falling asleep. This study therefore evaluated the effects of Rauwolfia vomitoria in the treatment of insomnia as well as its anti-oxidative potentials. Rauwolfia vomitoria 1,600 g leaf powder was extracted using cold maceration in methanol for 72 hours with intermittent shaking. Phytochemical analysis, total phenolic content, acute toxicity study, invitro anti-oxidative studies and sedative activity of the extract were done using standard methods. The phytochemical analysis showed the presence of alkaloids, saponins, tannins, flavonoids, steroids and terpenoids. Mean total phenolic content was estimated as 120.95 ± 1.31 mgGAE/g. No mortality was observed in both phases of the acute toxicity test. The LD50 was greater than 5,000 mg/kg body weight. In the anti-oxidant assays, at doses of 0.8 and 1.6 mg/ml, the methanol extract was at the same range of percentage inhibition of free radicals with the standard drug. The extract also showed reduced mean sleep onset similar to that of diazepam but more potent at higher doses. In conclusion, this study indicated rapid, long-lasting and significant anti-oxidant and sedative activities of Rawoulfia vomitoria methanol leaves extract which was however dose dependent.
A shape-based heuristic for the detection of urban block artifacts in street networks
Authors: Fleischmann Martin , Vybornova Anastassia
Published: June 2024

Street networks are ubiquitous components of cities, guiding their development and enabling movement from place to place; street networks are also the critical components of many urban analytical methods. However, their graph representation is often designed primarily for transportation purposes. This representation is less suitable for other use cases where transportation networks need to be simplified as a mandatory pre-processing step, e.g., in the case of morphological analysis, visual navigation, or drone flight routing. While the urgent demand for automated pre-processing methods comes from various fields, it is still an unsolved challenge. In this article, we tackle this challenge by proposing a cheap computational heuristic for the identification of ``face artifacts'', i.e., geometries that are enclosed by transportation edges but do not represent urban blocks. The heuristic is based on combining the frequency distributions of shape compactness metrics and area measurements of street network face polygons. We test our method on 131 globally sampled large cities and show that it successfully identifies face artifacts in 89\% of analyzed cities. Our heuristic of detecting artifacts caused by data being collected for another purpose is the first step towards an automated street network simplification workflow. Moreover, the proposed face artifact index uncovers differences in structural rules guiding the development of cities in different world regions.
Offender residence locations: exploring the impact of spatial scale on variability and concentration

In recent decades, the analysis of different geographic scales for studying the spatial patterning of crime has profoundly deepened our theoretical grasp of crime dynamics. However, a similar investigation is lacking when it comes to the patterning of offender residences, despite there being clear theoretical and empirical reasons for doing so, among them, the close relationship between where offenders live and where their corresponding crimes are committed. This paper delves into the concentration and variance of offender residences across different levels of spatial aggregation. The data used contains the locations of residence for known offenders in Birmingham between the years 2006 and 2016. Resident locations are aggregated to Output Areas (OA), nested within Lower Super Output Areas (LSOA), further nested within Middle Super Output Areas (MSOA). Descriptive and model-based statistics are deployed to quantify concentration and variation at each spatial scale. Results suggest that most variance (~48%) in offender residence concentrations is attributable to the largest spatial scale (MSOA level). Output Areas capture approximately 38\% of the variance. Findings open up discussions on the role of urban development in determining the appropriateness of spatial scale.

The Dichotomy Of Marriage: Incarceration And Emancipation In Manju Kapur’s The Immigrant
Authors: Singh Prikshit , Singh Prikshit
Published: June 2024

Marriage, an institution that has been revered and celebrated across cultures and civilizations throughout the ages, represents a sacred bond between two souls, uniting them in love, commitment, and trust. This union is not only critical for society but is also the foundation of the family unit. From the early days of human civilization, marriage has been portrayed in literature and has played a significant role in organizing societies. However, the institution of marriage has evolved over time, reflecting changing attitudes towards relationships and societal expectations. As sociologist Anthony Giddens argues in The Transformation of Intimacy, traditional marriage served as a central organization for social life, providing a stable foundation for the rearing of children and the maintenance of social order. This is evident in cultural traditions such as the Indian practice of arranged marriages, which emphasizes stability and continuity over romantic love as a means of ensuring the continuation of family lineage and cultural heritage. The legal and financial bonds formed through marriage can also provide a sense of security and stability, particularly in times of economic or personal uncertainty. Much like the natural world, marriage is subject to the forces of gravity that pull us towards the ground, towards the inevitable difficulties and challenges that arise in any long-term relationship. In marriage, varying expectations between partners can lead to significant challenges as they may have different views on their roles, responsibilities, and the relationship's future. Such disparities often stem from individual backgrounds, values, and experiences. Through her renowned work, The Immigrant, Manju Kapur masterfully captures the imperfections and challenges that arise within familial relationships over time, under various circumstances. In particular, Kapur's depiction of Nina and her husband's strained relationship, as well as the events that led to Nina's lonely existence in a foreign land, sheds light on the impact of migration on personal and family life. Nina's bond with her mother was also affected by her marriage, and the growing animosity among her marriage pushed her towards extramarital affairs, mirroring her husband's infidelity parallelly. Nina's personal life is thrown into disarray, as she struggles to navigate the complexities of human relationships and cope with the fallout from her actions. This research paper will delve into the intricacies of these issues and explore the importance of strong family ties and Nina's journey towards healing and recovery. On one hand, how the of marriage-imposed restrictions, curtailing the personal freedom of Nina to all the way towards a profound sense of freedom.
