Comprehensive Assessment Of The Impact Of Hydrogeological Factors On The Stability Of Open-Pit Slopes, Vokhid Rakhimovich Kadirov, Khurshida Yunusovna Norova, Zavkiddin Yahyo Oglu Ravshanov, Jamol Hasankhonovich Abdumalikov

Technical science and innovation

This paper presents an analysis of the influence of hydrogeological conditions on the stability of open pit slopes located within zones of tectonic disturbance. Based on field investigations and long-term hydrogeological monitoring conducted within the Almalyk ore cluster (Kalmakyr, Yoshlik-I, and Kurgashinkan deposits), the key factors affecting slope stability have been identified. It has been established that groundwater inflows from fractured and karstified Paleozoic rocks, as well as the presence of flooded abandoned pits, significantly increase the risk of slope deformation and failure. A special role is attributed to tectonic faults, which act as filtration channels for groundwater, leading to …

Development Of Technical Solutions To Prevent The Formation Of Sludge Regime At The Bottom Of A Well, Rustam Umarkhanovich Juraev, Jonibek Tursunov

Technical science and innovation

The trouble-free process of drilling wells largely depends on the effective cleaning of the borehole. The formation of a slurry regime at the bottom of the well leads to the process of repeated crushing of drilling fines, which in turn leads to a decrease in the mechanical drilling speed, to an increase in the energy consumption of the rock-crushing tool for repeated crushing, and also increases the risk of oil seals. In addition, the formation of a slurry regime at the bottom of the well increases the intensity of abrasive wear of the drilling rig. This article provides a theoretical …

The Well-Being Of International Doctoral Students—What Does It Look Like, What Affects It, And How Can We Support It?, Sean Nicholas, Pinjia Chan, Ivana Chan

Journal of Comparative & International Higher Education

There are multiple reviews on the well-being of international students and doctoral students, but to our knowledge, none on the well-being of international doctoral students. We undertook a scoping review to understand the state of well-being of international doctoral students, the factors that affect it, and the strategies that support it. We searched PsycInfo, EBSCO, Scopus, and ERIC for full-text, peer-reviewed articles published in English from 2003–2023. Fourteen studies were included in our scoping review. These studies suggest that international doctoral students report relatively low well-being in terms of negative emotions, attitudes toward the self, and social relationships. Their well-being …

How The Coherent Detector Works In Spread Spectrum Signals, Louay Habib Skef, Aymen Mohammed Khodayer, Jenan J. Abdulkareem

Al-Farahidi Expert Systems Journal

This research investigates the detection of direct sequence spread spectrum (DSSS) signals, comparing the performance of a traditional energy detector with that of a cross-correlation detector. While energy detectors are widely used, they suffer from reduced sensitivity at low signal-to-noise ratios (SNR) and require accurate noise power estimation. In contrast, the cross-correlation detector utilizes the processing gain of DSSS signals to achieve higher detection accuracy without needing prior noise estimation. Using MATLAB simulations, Receiver Operating Characteristic (ROC) curves were generated for both detectors. Results show that the cross-correlation detector achieves up to 30% higher probability of detection (PD) at a …

Toward A Conceptual Framework For Iot-Driven Adaptive Spatial Design In Open-Plan Office, Sarah Mohammed El Hawary, Ola Ali Hashem, Farzad Pour Rahimian

Journal of Art, Design and Music

The evolution of workplace environments has intensified the scrutiny of open-plan offices. The design paradigm of emphasising collaboration and sense of community within workplace has celebrated its facilitation of collaboration, providing open-plan office layout as example of collaborative space. Yet it has diminished individual comfort and privacy that are strengthened in enclosed-plan office layout. Studies revealed the demand of understanding occupant’s satisfaction. Since 85%-90% of one’s time is spent in indoor environment mostly at work, occupant’s satisfaction of physical environment or surroundings should be taken into count. This article proposes a comprehensive conceptual framework that leverages Internet of Things (IoT) …

Integrating Virtual Reality Technology Into Interior Design Education: An Experiential Study Within The United Arab Emirates, Sarah Mohammed El Hawary, Ola Ali Hashem, Farzad Pour Rahimian

Journal of Art, Design and Music

Students studying interior design can benefit from virtual reality (VR) technology, particularly when creating a digital three-dimensional (3D) model for their project.

Sustainable Materials And Emotional Durability Correlation In Interior Design, T.A. Hana El-Etr, Prof. Dr. Ola Hashem, Prof. Dr. Dalia M. Ezzat

Journal of Art, Design and Music

This paper studies the relationship between sustainable materials and emotional durability in interior design, within the Egyptian context through the case study: Galleria 40 complex. The concept of sustainability often focuses on ecological responsibility; the emotional impact to how the interior spaces affect long-term users, as well as reducing the consumption of unnecessary materials. Egypt has developed environmental rating systems such as the Green Pyramid and participated in international certifications like LEED, yet the incorporation of cultural identity with user experience in sustainable design remains limited. By tackling a mixed-method approach, involving a public survey and observational study of Galleria …
