(Dr. Samar Mayaleh, 2026-06-15) Sewar Asaad; Siwar Diab
In recent years, events, product launches, and public gatherings have grown rapidly due to the influence of social media and content creation trends. One essential aspect of such events is providing a warm and engaging welcome for guests. This project introduces a self-balancing reception robot designed to offer hospitality by combining modern technology with cultural values such as generosity and welcoming interaction. The robot enhances the image of events while presenting a futuristic approach to social interaction, making it significant from both technological and social perspectives. The main objective of this project is to design and develop an interactive self-balancing robot capable of welcoming and engaging guests in a modern and intuitive manner. The robot aims to reduce reliance on traditional human greeters by integrating automation, intelligent sensing, and human–robot interaction features. The development process involved designing the robot’s mechanical and electrical systems, including the two-wheel self-balancing structure and electronic integration. Key hardware components such as motors, sensors, microcontrollers, and a single-board computer were selected and integrated to support real-time balance control and interaction. A feedback-based control algorithm was implemented to enable stable self-balancing using real-time sensor data. In addition to balancing, the robot incorporates vision-based emotion detection, audio feedback, and a small display that presents interactive digital eye expressions. These features allow the robot to respond to user presence and emotional cues in a more natural and engaging way. The system was tested and refined in real-world conditions to ensure stability, safety, and effective interaction. While similar hospitality robots exist online, such systems are not commonly available in the local environment, and many do not combine self-balancing control with emotion-aware, multimodal interaction. This project demonstrates a unique approach by integrating balance control with intelligent human–robot interaction in a single platform.

EVALUATING THE EFFECTIVENESS OF A DELIRIUM PREVENTION PROGRAM ON NURSES KNOWLEDGE AND PERCEPTION REGARDING DELIRIUM IN INTENSIVE CARE UNITS
(An-Najah National University, 2026-08-12) Alashqar, Ahmad Fuad
Background: Delirium is a prevalent neurocognitive disorder and represents a major unintended neurocognitive dysfunction for critically ill patients. To enhance recognition and proper management, it is essential that staff possess the knowledge and perception to identify the signs and can commence the management of delirium while reducing the potential consequences that may arise. Purpose: The purpose of this study was to evaluate the effectiveness of a delirium prevention program on ICUs nurses’ knowledge and perception regarding delirium in intensive care units. Methods: Within group, quasi-experimental design was used to implement a delirium prevention program on ICU nurses. Data were collected between December 2025 to April 2026 at three stages pre-test, immediately post-test and as follw up test (after one month), all by using the same self-administered questionnaire. The sample size was 57 ICU nurses, recruited by using convenience sampling method. Result: A total of 57 ICU nurses participated in the study using a pre-test, immediate post-test, and one-month follow-up design. Before the intervention, nurses demonstrated low to moderate knowledge (Mean = 4.11 ± 1.68) and moderate perception levels (Mean = 2.78 ± 0.54), with major deficiencies in delirium assessment and ICDSC use. Following the educational intervention, nurses’ knowledge significantly improved to 8.96 ± 1.22, while perception scores increased to 4.62 ± 0.29. At one-month follow-up, knowledge and perception remained high with scores of 7.82 ± 1.10 and 4.40 ± 0.39 respectively, indicating good retention of learning outcomes. Statistical analysis using the Friedman test revealed significant improvements across all time points for both knowledge (χ² = 91.514, p < 0.001) and perception (χ² = 87.676, p < 0.001). The findings demonstrate that the delirium prevention program was effective in enhancing ICU nurses’ knowledge, confidence, and perceptions regarding delirium assessment and management. Significant differences were identified in nurses’ knowledge scores according to educational level, marital status, department, and experience. Nurses with master’s or PhD degrees achieved significantly higher knowledge scores than bachelor-prepared nurses (p = 0.013). Married nurses also demonstrated significantly better knowledge compared to single or divorced nurses (p = 0.015). In addition, nurses working in the MICU showed significantly higher knowledge levels than those working in SICU and CCU (p = 0.022). At the one-month follow-up stage, years of experience became significantly associated with outcomes (p = 0.038), where nurses with less experience showed better performance. No significant differences were found between sociodemographic variables and perception scores. Conclusion: The delirium prevention educational program had a significant positive effect on ICU nurses’ knowledge and perception regarding delirium and the use of the ICDSC tool. Nurses showed substantial improvement immediately after the intervention, and these improvements were generally maintained at the one-month follow-up stage. The study highlights the importance of continuous educational and training programs in improving nurses’ ability to identify, assess, and manage delirium effectively in intensive care settings. Ongoing reinforcement and periodic training are recommended to sustain knowledge retention and strengthen long-term positive perceptions and clinical practice.
THE IMPACT OF DIGITAL TRANSFORMATION ON SUSTAINABLE PERFORMANCE IN THE CONSTRUCTION SECTOR: THE MEDIATING ROLES OF SUPPLY CHAIN RESILIENCE AND CIRCULAR ECONOMY
(An- Najah National University, 2026-08-11) Amal Baradia
This thesis aims to explore the impact of digital transformation on sustainable performance through the environmental, economic, and social pillars in the construction sector in the West Bank. It examines the mediating role of the circular economy and supply chain resilience. This research utilized a mixed-methods approach involving 15 semi-structured interviews and a survey of 154 valid responses. Quantitative data were analyzed using structural equation modelling. The results showed that digital transformation does not affect sustainable performance directly; however, there is positive indirect effect through the circular economy and supply chain resilience. The circular economy fully mediated the relationship between digital transformation and sustainable performance, whereas supply chain resilience mediated only the relationship between digital transformation and social performance. The findings imply that construction companies should integrate digital transformation initiatives and circular economy practices in order to enhance sustainability. Some of the limitations of this research include its cross-sectional design and the use of a relatively context-specific sample, which may limit the generalizability of the findings, and only construction companies have been targeted. This thesis provides managerial insight by integrating digital transformation, the circular economy, supply chain resilience, and sustainable performance within a single framework and by demonstrating the full mediating role of the circular economy and partial mediating role of supply chain resilience in a developing country context. The findings indicate that transforming digital capabilities into circular and resilient operational practices enhances sustainability performance.
Performance comparison of VRF and chiller HVAC systems
(Dr. Ramiz Abdallah, 2026-09-08) Saed Shawahna; Mohammad Al-Rubu'
Project Summary This project presents a comparative study between two HVAC systems, namely the Variable Refrigerant Flow (VRF) system and the Air-to-Water Chiller system, for Sabat Wedding Hall in the West Bank. The main objective of the study is to determine the most suitable air-conditioning system based on energy consumption, operating cost, initial cost, and technical performance. The study began by analyzing the building characteristics, climatic conditions, occupancy, and cooling requirements. The cooling load was calculated manually and verified using Carrier HAP 6.2. The final cooling load adopted for the design was approximately 22.5 TR. Based on this load, both HVAC systems were designed to provide the same required cooling capacity. The results showed that the VRF system performed better in terms of energy efficiency and cost. The estimated annual energy consumption of the VRF system was 10,982.97 kWh/year, compared with 13,115.7 kWh/year for the Air-to-Water Chiller system. This represents an estimated energy saving of approximately 16.26%. At an electricity price of 0.7 NIS/kWh, the annual operating cost was estimated at 7,688.08 NIS for the VRF system, compared with 9,180.99 NIS for the chiller system, resulting in an annual saving of about 1,492.91 NIS. The initial cost comparison also favored the VRF system. The estimated initial cost was approximately $21,309 for the VRF system, while the Air-to-Water Chiller system required approximately $46,605.4. The higher chiller cost is mainly due to additional components such as pumps, chilled-water piping, FCUs, ductwork, insulation, and other mechanical equipment. Overall, the study concludes that the VRF system is the more suitable HVAC solution for Sabat Wedding Hall. Its ability to adjust cooling capacity according to the actual load makes it particularly appropriate for a wedding hall where occupancy and operating conditions vary significantly. However, the study also recognizes that chiller systems may be more suitable for larger buildings with high and relatively constant cooling demands.
