Prediction Of Maximum Local Scour Depth Due To Horizontal Jets Of Flushing Gate Using Artificial Neural Network, Adhy Kurniawan, Muhammad Sulaiman, Agus Maryono, Bambang Agus Kironoto, Amalia Ula Hazhiyah

Makara Journal of Technology

Local scour is a serious concern for hydraulic engineers. To maintain the reservoir capacity, flushing accumulated sediment is necessary, resulting in a turbulent and scouring jet from the flushing gate. Predicting the maximum scour depth from these water jets is crucial for civil engineers. Despite many proposed equations, one have shown consistent applicability due to the complex nature of the process. Ensuring accurate prediction between hydraulic parameters and the geometry of the scour hole in prototype experiments remains a key issue. To address this issue, this paper examines the use of artificial neural network (ANN) analysis as a computing device …

A Hybrid Reliability Framework For Spare Part Optimisation Under Uncertainty Of Marine Vessel Systems, Ahmad Fauzi Sagap, Ainul Akmar Mokhtar

Platform: A Journal of Engineering (PAJE)

Effective spare part management relies heavily on accurate reliability assessment. However, in new or complex systems, historical failure data are often limited, making traditional probabilistic reliability models inadequate. This paper proposes a hybrid reliability framework that integrates conventional reliability theory with fuzzy logic to address both aleatory (random)and epistemic (lack of knowledge) uncertainties. The approach combines crisp failure rate estimation using exponential distributions with fuzzy reliability modelling using the triangular fuzzy number (TFN) methodology and fuzzy logic to support dynamic decision-making for a maintenance plan. The degree of membership functions is derived from the TFN and provides the operator with …

Gravitational Property Theory, Monika U. Ehrman

Georgia Law Review

Isaac Newton and Albert Einstein defined and redefined the field of physics. Their theoretical work on gravity is still considered a monumental discovery of their respective times. Although born centuries apart, the theory of gravity each advanced is still essential. Newton’s theory is applied on Earth and throughout much of the solar system, while Einstein’s theory is used in special environments, such as near black holes. Neither theory is discarded, but instead used where appropriate. Likewise, gravitational property theory proposes that simple property theory—the ad coelum doctrine—is still appropriate for simple property, like stationary or vertical objects. And complex property …

Environmental Science And Sustainable Development: Behavioral Transformation To Knowledge System Integration For Sustainability Action, Ahyahudin Sodri, Herdis Herdiansyah

Journal of Environmental Science and Sustainable Development

Sustainability issues are now a global concern. However, knowing the root causes of problems and the target is not the only factor that constantly motivates change for the better (Wamsle & Osberg, 2022) as such change also requires encouragement from actors, including individuals, organizations, and communities. Therefore, the human aspect is crucial for the successful achievement of sustainability (Hariram et al., 2023). In other words, questions on sustainability are not just about "what should be done?" and also on “how to get people to do it?” and “why are currently available interventions not yet fully utilized?” …

Engaging Transnational Writing Assets In The Writing Center: New Pedagogical Directions For Supporting International Multilingual Students, Olalekan T. Adepoju

The Writing Center Journal

This article argues for a shift in writing center pedagogy toward prioritizing transnational writing assets as the basis of our work with international multilingual writers specifically and every writer we encounter generally. While writing center scholarship has paid attention to the influences of language, cultural and rhetorical differences among native and non-native English speakers/ tutors in the writing center, much of this discussion has taken the “comparative” route rather than a “trans-d” (transnational) route with potentials to transform our engagements with scholars, students, and writers from other parts of the world. This IRB-approved research reveals that international multilingual writers possess …

Event Triggered Integral Sliding Mode Controller Design For Multi-Input Multi-Output Nonlinear System, Mohammed K. Hamzah, Safanah M. Raafat, Shibly A. Al- Samarraie

The Journal of Engineering Research

In this manuscript, the design of event based Integral Sliding Mode Controller Eb-ISMC is considered for a nonlinear system with perturbation. The proposed controller uses a novel triggering strategy which is established according to some stability requirements. The primary benefit of this strategy is the effective usage of the system resources by reducing the total amount of control computations as compared to the classical or periodic version of ISMC. Closed-loop system stability analysis has shown that the suggested controller achieves the practical sliding mode PSM using the developed triggering control scheme. Moreover, Zeno behaviour is circumvented by developing suitable expressions …

N-Queens Problem Solving Using Apiary Organizational-Based Optimization Algorithm, Mais A. Al-Sharqi, Ahmed T. Sadiq Al-Obaidi, Safaa O. Al-Mamory

The Journal of Engineering Research

Researchers have utilised nature-inspired metaheuristic algorithms to find solutions for complex combinatorial optimisation problems and Non-deterministic polynomial (NP) problems. The N-queens problem is categorised as an NP-Hard problem as it becomes insurmountable for large N. This paper proposed a solution for the N-queens problem based on the Apiary Organisational-Based Optimisation Algorithm (AOOA). AOOA is a nature-inspired metaheuristic optimisation algorithm for NP-Hard problems comprised of multiple beehives inside the apiary, each with its population. In contrast to the backtracking method, AOOA employs a fitness function and randomisation techniques through seven stages to approach the optimal distributions of queens so they don’t …
