Item Restricted A Comprehensive Cyber Security Enhancing Strategy for Industrial Control Systems in Oil Industry(Saudi Digital Library) SHAYA ABDULLAH HUMUD ALSHAYA; Prof. Dino Giuli4 0Item Restricted an Integrating System of Gait Recognition by using Metric learningBODOR MOHAMMED ALMUBADDEL; Prof. Maria de MarsicoIn the field of pattern recognition, gait offers significant potential as a biometric. To date, data based on the features of a person's gait have gatherers using different sources, e.g., external sensors cameras. In contrast, recent developments in miniaturization have increased the use of internal sensors as smartphone accelerometer. Furthermore, the latest technological advances may offer the capability to engage in even more low-key data collection utilizing, e.g., The triple-axis accelerometers contained in most commercially available smartphones. Nonetheless, the use of only one data source may lead to some of the dynamic features of a person's gait may be lost, meaning that complex covariate conditions could significantly influence any such recognition system.0 0Item Restricted An Ontological Framework for Implementing Soft Mobility Knowledge Model in Urban Areas(Saudi Digital Library, 2023-07-17) Bahshwan, Rakan; De Lotto, Robertoهذه الدراسة عبارة عن أطروحة دكتوراه ساهمت في مجال التخطيط والتصميم والسياسة الحضرية لا سيما في مجال التنقل والنقل. كثيرًا ما يتم تكليف خبراء النقل والمؤسسات الحكومية بإجراء البحوث النظرية والتطبيقية من أجل تطوير وتحسين أداء أنظمة النقل الوطنية الخاصة بهم. يعد تخطيط التنقل مجالًا واسعًا يعتمد على بيانات من تخصصات علمية متعددة. عند التخطيط للتنقل من المهم تبني منظور شامل يأخذ في الاعتبار الجوانب المختلفة المتعلقة بالتنقل السهل. اليوم يعد التنقل السهل (مثل المشي والدراجات الهوائية) شكلاً أساسيًا من أشكال التنقل الحضري المستدام حيث إنه يوفر الطاقة، ويحسن الصحة، ويوفر خيارات نقل ميسورة ومرنة، ويقلل من الازدحام المروري، ويحسن العلاقات والاندماج الاجتماعي، ويعزز إمكانية الوصول، ويجدد الحياة في المساحات العامة، ويدعم السياحة، ويقلل من الانبعاثات الضارة. لكي يكون التنقل السهل فعال في بيئة حضرية يجب أن يكون مترابط ونظيري. بالإضافة إلى ذلك مطلوب عملية أو نظام دعم القرار لإدارة العناصر الحضرية وعناصر نظام التنقل السهل مثل التكاليف العامة للبنية التحتية، والتكاليف العامة للصيانة، والحوافز العامة المحتملة للدراجات الهوائية أو الدراجات الكهربائية، والتكاليف الخاصة لشراء وسائل التنقل، والتكاليف الخاصة للوقت، والنمذجة. في الحقيقة هناك حاجة إلى علم الوجود (الأنطولوجيات) الشامل والدقيق لعملية النمذجة وأنظمة دعم القرار. علم الوجود مناسب تمامًا لمواجهة تحديات تعقيد النظام والبيانات غير المنظمة بشكل جيد. يركز استخدام مناهج تطوير علم الوجود في المقام الأول على تحديد المفاهيم التي يمكن تفسيرها آليًا والعلاقات بين هذه المفاهيم في مجالها. يوفر ذلك فوائد كبيرة للعديد من التخصصات العلمية بما في ذلك التنقل والنقل. كما أن هنالك آخرون تابعوا أهداف إنشاء ومشاركة مفاهيم المجال بهدف السماح لخبراء المجال بإعادة استخدام معرفة المجال، وتمكين الباحثين من تحليل معرفة المجال والتعبير عن افتراضاته، ومساعدة الأفراد ووكلاء البرمجيات في فهم بنية مفاهيم المجال. وبالرغم من ذلك إلا أننا نجد نقصا في الاهتمام البحثي في مجال تخطيط التنقل للتنقل السهل. تم نشر عدد قليل من تطوير المشاريع الوجودية المتعلقة بالحركة اللينة منذ عام 2002. من أجل ذلك الغرض استخدمت هذه الدراسة مناهج تطوير علم الوجود لإنشاء نموذج معرفي للتنقل السهل في الويب الدلالي لتوفير معلومات واضحة ومبسطة وأساسية للمخططين والمهندسين والمشغلين في مجالات التنقل والنقل على جميع مستويات الحكومة والإدارة لتحقيق الاستدامة في قرارات التنقل الحضري. ركزت هذه الدراسة على العناصر الأساسية للعلاقة المكانية والتي تتكون من البنية التحتية للتنقل السهل، والشبكات للتنقل السهل، والأنماط للتنقل السهل، والتدفقات للتنقل السهل، ينصب تركيزها فقط على المشي وركوب الدراجات. تم اعتماد وتنفيذ المراحل التالية للدراسة: تحديد الهدف والنطاق، وجمع المعلومات واستخراجها، والهيكلة الأولية، وإضفاء الطابع الرسمي، والنشر، والتقييم. كما تم اختيار منهجية بسيطة لهندسة المعرفة مبنية على برنامج بروتيجيه "Protégé" وهي طريقة تم الاستشهاد بها على نطاق واسع لتطوير علم الوجود. أدى ذلك إلى تطوير نموذج معرفة شامل للتنقل الناعم باعتباره علم الوجود الثقيل في لغة أنطولوجيا الويب "OWL". تم تحديد العديد من مفاهيم العناصر المكانية الأساسية وحالاتها، وتم توضيح عدد قليل من حيث تحديد كيفية تصرفهم. أخيرًا وفر النموذج أيضًا تمثيلًا بيانيا للتنقل السهل والوصول التلقائي إلى البيانات القائمة على علم التنقل السهل. سوف يستفيد المهتمون بالتخطيط والتصميم والسياسة في المناطق الحضرية وخاصة التنقل والنقل من هذه الدراسة.43 0Item Restricted Arbitration in Maritime Disputes: A Comparative Study Between The Kingdom of Saudi Arabia and International Regulations(IMO International Maritime Law Institute, 2024-06-25) Aljuhani, Mustafa; Prado, RafealThe research covered various aspects of maritime negotiation, from basic rules and legal systems to detailed case studies and comparisons. The study provided an understanding of the current situation and potential future direction for maritime dispute resolution in Saudi Arabia within a global context. The dissertation began by examining the evolution of maritime arbitration, highlighting the significant role of foreign regulations such as the UNCITRAL Model Law and the New York Convention. The comparison of Saudi Arabia’s arbitration rules with global standards revealed a shift towards international norms while preserving unique legal and cultural aspects of the country. Case studies demonstrated the complexity of maritime arbitration and the necessity of understanding both local and international laws. Saudi Arabia has made significant strides in maritime law, including the introduction of a new dispute law and the establishment of the Saudi Centre for Business Arbitration (SCCA). The integration of Sharia laws into the arbitration process presents challenges but also offers a unique approach that aligns with local laws and culture. The future of maritime arbitration in Saudi Arabia looks promising, with continued alignment with global standards and innovative use of technology expected to enhance the effectiveness and appeal of Saudi Arabia’s arbitration system. Saudi Arabia’s participation in major maritime dispute conferences and collaboration with other countries will strengthen its global position. The lessons learned from Saudi Arabia’s experience are valuable not only for maritime law decisions but also for global considerations. As international trade continues to grow and evolve, the need for a flexible dispute resolution system becomes increasingly important. Saudi Arabia’s journey offers important lessons on balancing global standards with local laws, a crucial consideration for countries looking to improve their arbitration systems. The dissertation underscores the dynamic nature of maritime disputes, driven by changing trade patterns and legal regulations worldwide. As Saudi Arabia improves its dispute resolution capabilities, it contributes to the advancement of maritime arbitration globally. The study of maritime arbitration in Saudi Arabia reveals the complexity and dynamism of this field, which is critical for the smooth operation of international maritime trade. The insights and lessons derived from this research are valuable for policymakers, lawyers, and researchers, aiding in the future resolution of maritime disputes both within Saudi Arabia and in global contexts.32 0Item Restricted BIO-INSPIRED RESPONSIVE SHADING SYSTEMS (A Comprehensive Review of Shading Systems Inspired by Nature)NOURELDINE OSAMA MOHAMMED BAKHIT; GIULIANA IANNACCONEGlobal warming is a problem mankind is currently facing. The building industry accounts for 40% of the total energy consumption and Carbon Dioxide (CO2) emissions and thus plays a critical role in addressing global energy and climate forcing issues. In the middle east, all buildings have HVAC systems to maintain thermal comfort. The energy produced to maintain these systems generate greenhouse gas emissions from burning fossil fuels like coal and natural gas. The energy used primarily for cooling loads in the region accounts for nearly 50% of the total energy consumed in buildings, which is a very high level compared to other developed countries. Having a high-performance envelope in a building always helps in reducing energy consumption. However, a responsive shading system can help even further in energy performance and increase thermal comfort. Where better to get inspired to design a dynamic shading system than from nature. The term biomimicry is what nature offers to solve problems in architecture or in engineering. Mother nature should always be the number one source of inspiration for designers, where they can find the best ideas and opportunities to create and innovate new technologies. This paper explores bio-designed dynamic shading systems of modern buildings already built. It discusses the various types of shading systems, the inspired biological systems, the materials used, and the mechanism. Modeling and simulations are also performed to assess energy performance, visual comfort, and thermal comfort. Comparisons between the shading systems will be shown as it’s important to show their performances in different categories. After investigating the case studies, a new responsive shading system inspired by nature will be designed to have an effective and efficient performance in terms of shading, energy, and visual comfort. A focus will be done on the actuation of the shading system, as the actuation is a key component of the entire system. A summary of the case studies and the new shading system is eventually done to show the similarities and differences between the systems. The paper concludes by offering recommendations and setting guidelines for architects and engineers when innovating a responsive shading system for buildings in the future.2 0Item Restricted Caratteristiche Craniofacciali in soggetti affetti da Displasia Ectodermica in età evolutiva(Saudi Digital Library) NADIA OTHMAN A ALKHAMIS; Prof. Gabriela Piana0 0Item Restricted Continuum Modelling and Simulation for Viscoelastic Materials(University of Padova, 2024-06-25) Alrashdi, Muhanna; Giusteri, GiulioA class of continuum mechanical models aimed at describing the behaviour of viscoelastic fluids by incorporating concepts originated in the theory of solid plasticity is introduced. Within this class, even a simple model with constant material parameters is able to qualitatively reproduce a number of experimental observations in both simple shear and extensional flows, including linear viscoelastic properties, the rate-dependence of steady-state material functions, the stress overshoot in incipient shear flows, and the difference in shear and extensional rheological curves. Furthermore, by allowing the relaxation time of the model to depend on the total strain, we can reproduce some experimental observations of the non-attainability of steady flows in uniaxial extension, and link this to a concept of polymeric jamming or effective solidification. Numerical simulations are presented to further illustrate the properties of the proposed model.9 0Item Restricted Curating Digitization System: Digitizing Value-driven practices of Intangable Cultural heritage Fashion for Nation branding and Safeguarding(Saudi Digital Library, 2023-07-18) Alsager, Rynad; Vacca, Federica; Carulli, MarinaThis thesis explores the concept of Nation Branding and its influence on sustainable development through the digitization of a country’s Intangible cultural heritage (ICH) resources, to enhance the Saudi brand spiritual identity and Safeguard ICH fashion. focusing mainly on ICH fashion craftsmanship. Fashion is a crucial aspect of a country’s visual identity, it’s a source of pride for a country’s people, reflecting its traditions and values, contributing to both its economy and culture. However, in the case of Saudi Arabia rebranding and digital transformation, we notice a gap as there is limited access to information regarding Saudi ICH fashion on the internet, specifically relating to its intangible values that drives its fashion design aesthetics and functionality. This creates a gap in communication and connection between the Saudi Fashion identity and its digital generations fashion identity. the researcher is proposing a digitization system to establish and sustain an accessible digital point for craftsmanship and driving values of Saudi CH fashion on the internet. To address this issue, the research methodology employed a curative-innovative digitizing system, incorporating a qualitative Hybrid design using exploratory, historical documentation, and information design methods. Information design stage was in partnership with The Royal Institute of Traditional Arts (TRITA). As it was established as part of the Saudi Vision 2030 initiative to safeguard and educate Saudi Arabia’s culture for new generations as well as to promote its heritage with the world. It is important to note that the project section of the research represents the author’s opinion and is not endorsed by the Royal Institute of Traditional Art. Furthermore, it should be emphasized that this is a hypothetical scenario reflecting only the researcher’s perception. Moreover, the project part investigated Sustainability as driven-value to test the efficiency of the methodology, and choose Najd, the central region women’s fashion as scope to investigate it, and Al-Miqtaa costume craftsmanship as digitization sampling. The research findings confirm the validity of this digitizing system and highlight the value-driven nature of Saudi CH fashion, representing rooted and active values that can be a competitive advantage for the Saudi economy and branding archetype. Additionally, as part of the sampling project, it has been validated that sustainable design-thinking is deeply embedded in the Saudi society’s inheritance, resulting from the economic and environmental challenges they faced.11 0Item Restricted Data analysis and application for Unmanned Aerial Vehicles’ communication networks(Saudi Digital Library) WESAM ABDULRAHMAN ABDULLAH RUKUN; Francesca Cuomo2 0Item Restricted Decision-making In Different Cultures: Essays In Experimental Economics(Saudi Digital Library) BASSIM ABDULLAH HAMAD ALLAHEEB; Professor Luigi Mittone & Professor Matteo Ploner6 0Item Restricted Definition and evolution of smart citiesLULWAH SULIMAN ALHUSSAIN; PREZIOSO MariaThe thesis is aimed at comparing the existing literature on smart cities in order to give a definition and interpretation of this recent phenomenon.

In order to measure the differences in these exchanges that is, altruistic, trust and reciprocal behaviour, the ultimatum game, the trust game, and the dictator game respectively were used. These are experimental instruments that are traditionally used and referred to in the literature of behavioral economics. The results of these experiments varied significantly based on their partner’s gender and culture and on occasions when their identity was revealed to the other partner. This thesis contributes to the study of intercultural relationships, economic behavior, and perception of gender discrimination in Italian and Saudi Arabian people. There are two main aims of this study; first, to describe exchange behavior and gender differences across two cultures (Italian and Saudi Arabian) and its effect on economic behavior. Second, to investigate the perception of gender discrimination in the workplace and occupational preferences in Saudi Arabia, exploring the extent gender discrimination is associated with age, region, marital status, and education level. With the introduction of new policies, both men and women in Saudi Arabia are able to receive higher education in addition to the opportunity to study abroad. Moreover, a lot of cultural changes under Vision 2030 are occurring in Saudi Arabia which is breaking the barriers in women’s lives which are changing their strict gender role stereotype. This study is important in providing an early observation of the initial implementation of Vision 2030 and of the perception of gender discrimination in the minds of people of Saudi Arabia which has not yet been fully explored; the latter is the prime motivation of this study. My two chapters make several contributions to the literature regarding behavioral insights across cultures and the perception of gender discrimination in Saudi Arabia. The first chapter explains how cultural differences and gender influence behavioral patterns such as altruism, trust and reciprocity through the ultimatum game, the trust game, and the dictator game respectively among the people of Italy and Saudi Arabia. This study was able to investigate how the culture and the gender of participants affect their exchange behaviors. The second chapter shows how people perceive gender discrimination and how gender discrimination influences occupational preferences and the environment in the workplace in Saudi Arabia. A survey or online questionnaire was used to analyze people’s perception of gender discrimination in Saudi Arabia. Overall this thesis confirms the persistence of the existence of gender differences in behavioral patterns across cultures. Saudi Arabian females accept less than Italian male and female participants. However, these Saudi Arabian female participants sent more tokens when they were paired with Italian females. Italian participants were observed as being more trustful on the whole than Saudi Arabians and Italian females were seen to be more generous and altruistic than Saudi Arabian participants. Subsequently, significant gender differences were noted in the perception of and attitude towards gender discrimination, for example, Saudi Arabian males favor gender discrimination in Saudi Arabian society. There are clear differences in perception of and attitude towards gender discrimination according to educational level, for example, males with higher education did not favor gender discrimination. It is suggested that this is primarily due to the distribution of gender-typical stereotypes in Saudi society.2 0Item Restricted ENHANCING PREDICTIVE CAPABILITY OF MODELS FOR SOLUBILITY AND PERMEABILITY IN POLYMERS AND COMPOSITES(Saudi Digital Library, 2023-05-15) Albahrani, Abdullah Abdulmohsen; Doghieri, FerruccioThe interpretation of phase equilibrium and mass transport phenomena in gas/solvent - polymer system at molten or glassy state is relevant in many industrial applications. Among tools available for the prediction of thermodynamics properties in these systems, at molten/rubbery state, is the group contribution lattice-fluid equation of state (GCLF-EoS), developed by Lee and Danner and ultimately based on Panayiotou and Vera LF theory. On the other side, a thermodynamic approach namely non-equilibrium lattice-fluid (NELF) was proposed by Doghieri and Sarti to consistently extend the description of thermodynamic properties of solute polymer systems obtained through a suitable equilibrium model to the case of non-equilibrium conditions below the glass transition temperature. The first objective of this work is to investigate the phase behaviour in solvent/polymer at glassy state by using NELF model and to develop a predictive tool for gas or vapor solubility that could be applied in several different applications: membrane gas separation, barrier materials for food packaging, polymer-based gas sensors and drug delivery devices. Within the efforts to develop a predictive tool of this kind, a revision of the group contribution method developed by High and Danner for the application of LF model by Panayiotou and Vera is considered, with reference to possible alternatives for the mixing rule for characteristic interaction energy between segments. The work also devotes efforts to the analysis of gas permeability in polymer composite materials as formed by a polymer matrix in which domains are dispersed of a second phase and attention is focused on relation for deviation from Maxwell law as function of arrangement, shape of dispersed domains and loading.14 0Item Restricted ERTH (HERITAGE) - A Contemporary Narrative of the Past Preserving Traditional Handmade Crafts: Plaster CarvingOMAYMAH MOHAMMAD MOHAMMAD ALAZHARI; Lorenzo ImbesiIn recent years, traditional handicrafts saw a sharp decline in consumer purchases. Some of the reasons behind this shift are globalized markets and technological advancement. Traditional handicrafts and technological innovation may seem far from another, yet technological change is now certain in any field. That may lead many in the artisanal community to consider their retirement. However, the current wave of cultural revival in the Kingdom of Saudi Arabia is restoring the narratives of these crafts once again. This research was initiated through a set of interviews with cultural enthusiasts and an exploration of the plaster-carving craft with specialized artisan. The goal was to explore the possibilities of traditional products that may be mass-produced, and to find a new balance between traditional techniques and modern technologies, one that honors traditional processes and maintains the artisan as the key figure in the production process.5 0Item Restricted HYBRID RETAIL EXPERIENCE: Interpretative Model and Concept Design for laFeltrinelli Megastore(Saudi Digital Library) KHADIJAH JAWAD MOHAMMED ALKHUWAITEM; Prof. Claudio Dell'Era0 0Item Restricted Hypopharyngeal Reconstruction: Retrospective study of reconstruction of the pharynx with comparison of three alternatives(Saudi Digital Library) NASSER IBRAHIM ALABDULAALY; Dr.Francesco BenazzoThe hypopharynx is the last part of pharynx that connects the oropharynx above to the esophaguses below. It's responsible for moving the food bolus by a series of coordinated muscular contractions, while distension and vibration of the pharyngeal wall are responsible for phonation. Hypopharyngeal squamous cell carcinoma (HSCC) accounts for about 5% of all head and neck cancers and includes primary hypopharyngeal tumors and advanced tumors originating from other sites, in particular, the larynx. The majority of these cancers present with large bulky neck nodes, distant metastasis, and extensive sub- mucosal disease. The available therapeutic options are surgery followed by adjuvant treatment or organ preservation in the form of chemoradiation therapy. Although primary treat- ment of hypopharyngeal cancer is increasingly relying on nonsurgical modalities, for selected advanced stages and for patients in whom nonsurgical treatment fails, surgery remains the only curative option. Surgical treatment of advanced hypopharyngeal cancer remains a challenge for surgeons due to the di culty of restoring digestive continuity, considering the dis- tance covered, and the maintenance and provision of adequate blood supply to the reconstructive grafts. The reconstructive approach depends on the amount of pharyngeal resection re- quired. In some patients, the pharyngeal wound can be primarily closed, but cases with extensive partial or circumferential pharyngeal resection require reconstruction to close the defect. Several techniques have been developed and applied to the reconstruction of hy- popharyngeal defects, including cervical aps, tubed cutaneous and myocutaneous chest aps, gastric pull-up, and free jejunal autografts. The ideal reconstructive technique for such defects, possibly involving the cervical esophagus, should o er the patient a prompt, acceptable functional recovery with the lowest morbidity and mortality and fair quality for their remaining life. Pharyngeal reconstruction with a free jejunal graft has rapidly evolved to become a choice among these procedures and has been widely used to achieve relatively lower mortality and morbidity; the reported success rates for the procedure reach 95{100%. Its popularity is due to anatomical and physiological advantages: the transposed short intestinal tract is anatomically well adapted to the reconstruction site, provides low stula and stricture rates, and ensures rapid recovery to permit adjuvant radiotherapy and good functional recovery. The rst few chapters of this dissertation will try to lay a well-rounded overview of pharynx and larynx anatomy and physiology. I will then review the existing modalities of reconstruction and survey the advantages, disadvantages. The last chapters, on the other hand, will build upon the patient's records that were reviewed to determine the indications for radical resection, location, and stage of the primary tumor, postoperative complications, morbidity, mortality, tumor re- currence, and survival. proceed to employ a retrospective model study of the pa- tients treated in our Otorhinolaryngology department at the Policlinico S. Matteo di Pavia. 70 0Item Restricted IDENTIFICAZIONE DI BERSAGLI INTRACELLULARI DI UN AGENTE ANTILEISHMANIA E CARATTERIZZAZIONE FLUORIMETRICA DI PTERIDIN REDUTTASI 1(Saudi Digital Library) AHMED ABDULLAH ABDULMOHSEN ALHAMMAD; Relatore: Prof. Glauco Ponterini.
