This paper presents some perspectives on undergraduate students’ hybrid education learning experiences in the United Arab Emirates (UAE). It is recognized that hybrid education involves a combination of both online and face-to-face learning environments. Now, in order to deliver courses in the hybrid mode, instructors have to utilize technology, involving various online learning tools, as well as face-to-face classroom activities – thereby providing a deeper and more effective learning environment, from the students’ perspective. Evidently therefore, the hybrid teaching-learning environment involves various challenges – in social, technological, economic, environmental and political (STEEP) terms. In the UAE, such challenges are further compounded by the students’ inability to project their personal characteristics, or to gain practical skills – thereby creating remarkable negative effects on the students’ persistence, engagement, and academic achievement. The subjects of the present study are the undergraduate students of the Logistics Engineering Technology program at the Higher Colleges of Technology (HCT), Abu Dhabi Men's Campus (ADMC). The methodology of the study involved direct discussions, Likert scale as well as an online survey – these being designed in such fashion as to elicit an accurate reflection of the students’ experiences. The results of the study show that hybrid learning involving the use of advanced technologies - Social Robotic Telepresence System (SRTS), 3D Hologram, Spherical Videos (360°), Augmented and Virtual Reality (AR & VR) - can be a promising solution to fill some of the identified hybrid learning gaps. The results also show that the effective use of such tools can promote the students’ social interactions, as well as enhance the students’ virtual and realistic experiences.

For technologies used in environmental analysis and control, it’s important to have knowledge integration among the concerned in process industries so that all involved can achieve their desire key performance indicators. We cannot expect that all will have in-depth knowledge on environmental analysis and management pertaining to the areas like effluent treatment plant, demineralized plant, or reverse osmosis plants. Water, wastewater treatment and control are very important since this contribute to utility management. The process involves generating good quality of water from raw water and further used in process. Industries have responsibility to manage wastewater by treating, segregating waste and use treated water for gardening etc. Pollution control boards have brought stringent norms to monitor this. Post global pandemic situation, it has become more challenging for industries due to various challenges like manpower, hesitance to move in the field for even routine check where waste water is brought at common place which includes human waste from toilets for treatments in ETP. Service availability in time is too questionable. Without knowledge integration among the suppliers and the users, performance of water and wastewater management cannot be enhanced. Hence, it’s important to study impact of knowledge sharing on key performance indicators on both sides.

The advantages of using UHPC in the LFRS of 60-story modern office buildings are investigated. Commercial ETABS is used to design four 60-story buildings using 60 MPa conventional concrete and 150, 185, and 220 MPa UHPC focusing on evaluating the seismic performance and economic advantages of both buildings. The LFRS consists of special shear walls coupled with spandrel beams while the gravity consists of square columns and flat plates. The results indicated that 150MPa and 185MPa UHPC present favorable economic advantages and improved overall seismic performance when compared to 60MPa concrete, however, the increase from 185MPa to 220MPa did not yield any significant benefits in terms of cost savings and seismic performance in this study.

This paper represents the analysis of the results obtained from some experiments conducted on a Direct Evaporative Cooling System (DECS). The results are recorded as a part of a capstone project that took place in the Mechanical Engineering Department at Abu Dhabi Men’s College. The use of standard psychrometric chart in the analysis revealed better understanding of the concepts and basis of evaporative cooling process. As a result, new findings, regarding the effect of the outdoor relative humidity on the sensible and latent heat were obtained It was identified graphically using the psychrometric chart and through calculation that both sensible (Qs) and latent (Ql) heat decrease as the relative humidity increases. More importantly it was found that the rate with which Qs and Ql gets lower as RHo increases.. The use of psychrometric chart also revealed clearly that all the experiments conducted were very close to adiabatic, confirming strongly the theoretical analysis. Analysis showed better understanding of the process under different ambient operating conditions. Supplying water at lower temperature was shown to have a big impact on the DEC performance.

Security has consistently been a significant worry for mankind. Today we have video surveillance cameras in schools, hospitals and every other public place that help keep these spaces secure. This is also including places with vehicles such as parking spaces and garages, and it would be embedded with a security guard that would also help monitor and verify entrance of any incoming vehicle, as well as controlling the opening and closing of the gate. The project will aim to develop a smart car plate recognition device that can monitor and survey the area, as well as detect and analyze vehicle license plates. A sensor will detect the incoming vehicle, then a camera will take a screenshot of the front of the vehicle with the license plate. The license plate is scanned then checked whether it is registered to determine whether it is allowed or denied entry, and the device will troubleshoot by sending SMS to a fixed phone number regarding any issues. We will use a supervised Machine Learning Optical Character Recognition model known as Tesseract AI. This pre-trained, multi-language AI will detect and extract the numbers and letters on the license plate. Before this process starts, we will clean the image of any noise by performing changes to the original image, such as switching to grayscale and brightening, in-order to increase the accuracy of the OCR and minimize error. These extracted numbers and letters will then be checked within the database one entry after the other until it detects a match. This device will be a direct upgrade over the traditional system of simply including a CCTV camera and a guard as the device will operate independently to a point that no human input is required and will require no installation of on-site servers or setup of databases, thus saving manpower and reducing cost and complexity.

Connected and autonomous vehicles (CAVs) systems have the potential to reduce accidents, improve mobility for the disabled and elderly, increase road capacity, save fuel, and reduce pollution in the transportation system. Congestion is a common problem on every road network, particularly in intersections. With the inevitable deployment of CAVs, it is necessary to explore how they can operate at junctions in terms of traffic operation and safety. The study's primary objective is to determine the impact of CAVs on intersection traffic operations and safety. A 4-legged signalized intersection simulation case study with 5 various penetration rates of CAV scenarios (0 percent, 25 percent, 50 percent, 75 percent, and 100 percent of CAVs) was carried out using VISSIM microscopic traffic simulation to examine the impact of CAV on traffic performance. The safety impact of the different scenarios was evaluated using the Surrogate Safety Assessment Model (SSAM). The results showed that CAVs could significantly improve traffic movement with the increase of penetration rates, even when traveling with shorter headways, to improve road capacity and reduce delay and travel time. The delay reduction was from 4 percent to 10 percent, with the penetration rates between 25 percent and 100 percent. At the same time, the travel time reduction was between 3 percent and 8 percent, with the penetration rates between 25 percent and 100 percent. Moreover, the results showed that CAVs could improve safety significantly by reducing 35 percent of accidents. As for the delay cost, CAVs can reduce the delay cost by at least 3.25 million U.S Dollars per year by each 4-legged signalized intersection when the intersection is fully functioned with CAVs.

The incorporation of Recycled Concrete Aggregates (RCA) aiming to produce Recycled Aggregate Concrete (RAC) mixtures tends to reduce CO2 emissions, cost and energy consumptions; however, the existence of old cement paste (adhered mortar) attached to the surface of RCA leads to inferior fresh, mechanical and durability properties compared to conventional concrete. This paper reports on a mechanical treatment method implemented to partially remove the adhered mortar in RCA samples placed inside a rotating concrete truck mixer. The impact of the RCA with the metallic walls was determined in terms of mass loss, circularity index and image analysis within different time frames. Based on the results, the optimum mechanical treatment duration was found to be 3 hours. Following, 17 different combination mixtures including partial or full replacement percentages of untreated, treated, coarse or fine RCA at 0.25 and 0.50 w/c ratios were investigated by means of mechanical and durability properties. For high w/c ratios, the inclusion of mechanically treated aggregates was more beneficial in terms of compressive strengths, while for low w/c ratio, the early-compressive strengths were enhanced. Even though the splitting tensile strengths were not significantly affected for low w/c concretes, the inclusion of treated aggregates reduced the chloride permeability and drying shrinkage of all mixtures.

This paper studies the effect of a type-2 fuzzy adaptive PID (type-2 FAPID) controller on the performance of a mechatronics system such as differential mobile robot. In the proposed adaptive controller, the PID controller gains are automatically tuned using type-2 fuzzy systems. The performance of controllers is compared by simulating the robot traveling an undisturbed straight route and a circular route. Torque load disturbance is later added to the DC motors to draw better comparisons between the type-1 and type-2 FAPID controllers. The findings of this paper showed that the designed type-2 fuzzy adaptive PID controllers have enhanced the performance of differential mobile robot.

Fusion360 was used to design a vehicles chassis with and without B pillar, then implementing structural analysis to measure the structural rigidity, and capability to handle stresses, and total deformation. Two car chassis designs are made, with and without the b-pillar and subjected to two structural stress tests, a side and a roof force impact. The stress analysis performed in Fusion360 shows that the b-pillar has little effect on the roof support, where the difference in maximum stress and total deformation is very small. However, a very significant difference is recorded in the side force test where a 111% more deformation occurs, and 32% more maximum stress handled by the existence of a B-pillar. This result is logical as the B-pillar acts as a side reinforcement more than reinforcing the roof.
