Their ability to produce dense parts with optimized magnetic properties was compared. Two different Fe6.5Si powders were used during this project. One was sourced from Hoganas, while the other was sourced from HLPowder. Both powders were characterized in terms of density and flowability. Parts printed with SG-3DP achieved positive results as their density averaged of around 95%. Cubes and shells were printed and the shells resulted in a stronger <001> crystallographic texture compared to that of the cube, which is beneficial for magnetic applications. Multiple parameters printing parameters were tested with LPBF printing before obtaining parts that yielded an average density of around 99% and were less prone to cracks. Crystallographic orientations varied depending on the part, with the reference cubes exhibiting a more dominant <111> texture, while the Hilbert cross-sectional parts exhibited a more dominant <101> texture. Magnetic testing of toroidal parts fabricated with the SG-3DP and LPBF showcased the same magnetic saturation of 1.5T. However, the LPBF toroid performed better than the SG-3DP toroid in terms of permeability (164), coercivity (346 A/m), and in terms of power losses (12.7 W/kg).6 0Item Restricted Addressing Manpower Challenges for Saudi Arabia's 2030 Tourism Vision(Saudi Digital Library, 2026) Almuhawas, Turki; Robin, ReidSaudi Arabia has embarked on an ambitious Vision 2030 strategic framework to steer the economy away from its heavy reliance on oil revenues. A key pillar of this vision is to aggressively develop the tourism sector as a major economic driver and catalyst for diversification. The government recognizes immense untapped potential in leveraging the country's rich cultural heritage, natural landscapes, and religious significance to position it as a premium global destination. Towards this goal, Saudi Arabia has already kickstarted several giga-projects like the $500 billion futuristic NEOM city, the ultra-luxury Red Sea Project, and the wellness-focused Amaala resort, among others (Alam et al., 2021). The overarching vision targets increasing tourism's contribution to the GDP from a mere 3% currently to an impressive 10% by 2030 (Al-Mohmmad & Butler, 2021). This paradigm shift is expected to catalyze millions of new employment opportunities across the tourism value chain - from hotels, airlines, and tour operations to culinary, leisure, and heritage management roles. However, perhaps the biggest challenge in realizing these lofty ambitions is developing an adequately skilled and capable Saudi workforce for the rapidly expanding tourism industry (Al-Mohmmad & Butler, 2021). Historically, the sector has been heavily reliant on expatriate labor, with limited interest from nationals who preferred careers in the public sector or other industries deemed more prestigious.5 0Item Restricted Adopting BIM for facility management of the ENISE(Saudi Digital Library) MUNIF MENWER ALHARBI; Isam shahrour0 0Item Restricted AMMONIA CRACKING BY ATMOSPHERIC PRESSURE NH3 PLASMAS FOR HYDROGEN PRODUCTION(Saudi Digital Library, 2025) Awaji, Majed; Gries, Thomas; Belmonte,ThierryAmmonia plays a crucial role in the energy sector, particularly as a more easily transportable hydrogen carrier. Japan, for example, uses it to produce the hydrogen needed for its energy mix. At present, its production is based on the Haber-Bosch process, which operates continuously and is not suited to intermittent energy sources such as solar or photovoltaic energy. Using microwave plasma to decompose ammonia could offer a viable, catalyst-free alternative that is compatible with localized and alternative energy production. In this study, we investigated the dissociation of NH3 in a microwave plasma operating at 2.45 GHz. A literature review revealed that the decomposition of ammonia has often been studied in high dilution with carrier gases such as nitrogen or argon. However, the fundamental properties of the ammonia molecule and the radicals it generates (NH, NH2) remain incomplete, which complicates the development of satisfactory models for ammonia-rich plasmas. The experiment required the design of a special reactor equipped with a resonant cavity device and advanced diagnostic equipment. An ammonia plasma under reduced pressure (10 to 500 mbar) was generated using a 2.45 GHz microwave source, with strict precautions to ensure the safety of operators. The gases were analyzed using infrared absorption and gas chromatography, enabling precise dissociation rates to be obtained. The study revealed that dissociation increases with power and pressure but decreases with gas flow rate. Rotational temperatures of around 2,500 K and an electron temperature of around 0.5 eV were determined. The results obtained show NH3 conversion of up to 97% with an energy efficiency of 8%, and up to 14% with a conversion of 28%. Although these performances are promising, they are still inferior to thermal processes assisted by catalysts. Process efficiency is highly dependent on the management of thermal and electronic gradients within the microwave cavity. Finally, the influence of the fused silica reactor tube surface was demonstrated, showing an improvement in NH3 dissociation thanks to heterogeneous interaction with the radical species. A transition to atmospheric pressure operation could further improve the energy efficiency of the process, making it more competitive with thermal approaches while avoiding the use of catalysts. However, the viability of this technology will require ammonia to be produced from decarbonized sources to ensure a favorable carbon balance.0 0Item Restricted An Analysis on how to utilize Human Resources to create or maintain a Competitive advantage within the modern business environment.(Saudi Digital Library) ALANOUD YARUB A ALMADANI; Prof. Regine GLASS10 0Item Restricted An examination of expatriate managers have on local tradtions and culture in the work place case study crown plaza Riyadh hotel(Saudi Digital Library, 2025) Almijlad, Ahlam; Barnes, ChristinaThis research examines the impact of expatriate managers on local traditions and culture within the workplace, using the Crowne Plaza Riyadh Hotel as a case study. In the context of Saudi Arabia’s rapidly evolving hospitality industry under Vision 2030, the study explores how foreign managerial practices interact with deeply rooted cultural norms. Drawing on globalization cultural theory, cross-cultural adjustment theory, social exchange theory, and cultural role theory, the research employs a mixed-methods approach combining secondary literature review with primary data from semi-structured interviews, surveys, and document analysis. Findings reveal that expatriate managers contribute positively by introducing international standards, fostering cultural exchange, and enhancing service quality, while challenges persist in cultural sensitivity, communication barriers, and adaptation to local managerial preferences. Quantitative results indicate strong perceptions of respect for local culture among expatriates, though qualitative insights highlight areas for improved cultural integration and training. The study offers practical recommendations for fostering inclusivity, reducing cultural conflicts, and leveraging diversity to achieve organizational goals, contributing to both the theoretical understanding and practical management of cross-cultural dynamics in the hospitality sector6 0Item Restricted An investigation of the socioeconomic status impact and consumer motivation over spa experience in Riyadh, Saudi Arabia(Saudi Digital Library) ALI MANSOR ALEIDAN; جمال الشيباني4 0Item Restricted ANÁLISIS DEL ARBITRAJE EN ARABIA SAUDÍ A TRAVÉS DE LA RECIENTE LEY SAUDITA: TRADICIÓN Y MODERNIDAD EN LA RESOLUCION DE CONFLICTOS EN EL COMERCIO INTERNACIONAL(Saudi Digital Library) RAED AOUDA A ALJOHANI; MARTA CONZALO QUIROGAItem Restricted Analyse comparative des deux émissions de débat télévisuels sur le thème de "la migration" en arabe et en français.ABEER AMER SALEH ALAMRI; Mustapha KrazemLa thèse porte sur l’analyse linguistique des deux émissions de débat politique : l’une française, et l’autre arabe ayant le même sujet « la migration ». Elles sont diffusées presque à la même période « Septembre/ octobre 2015 » ; le moment où l’Europe a connu une augmentation considérable dans le nombre des réfugiés arrivant sur son territoire, au point que cela a pu engendrer une situation tendue entre les pays membres de l’UE. Le but de cette thèse est de chercher, dans un premier temps, quels sont les termes utilisés pour désigner les déplacés dans les deux émissions, et en quoi les appellations/dénominations se ressemblent ou se diffèrent ? Ensuite, nous cherchons les raisons derrière ces choix que les participants dans les débats ont fait.Item Restricted Analyse comparative du régime de responsabilité administrative entre la France et l’Arabie Saoudite(Saudi Digital Library) AHMAD IBRAHIM ALSUKITY; Agathe VAN LANG2 0Item Restricted Analyse de l'activité des élèves et développement de la personnalité en classe de mathématiques.
