A ship collision is one of the most hazardous incidents that may occur at sea. The circumstances that lead to these incidents vary widely, but some of the most prevalent forms of maritime collisions include side collisions, bow-on collisions, stern collisions, and allision. Any of these errors can rapidly turn catastrophic for the crew or passengers on board the implicated boats. Case studies have revealed that, contrary to common assumption, the majority of crashes are caused by the bridge team’s carelessness and inability to fulfil fundamental navigational responsibilities. In this study, a Maritime Law of Tort Collision Regulations Mobile Apps was designed to determine whether the navigator or master is negligent or not by examining the navigator’s or master’s actions that are either above or below the standard of care. This mobile-based solution was created using the Agile Methodology. The key rationale for implementing agile is that the main characteristics of mobile applications are that user requirements change over time, are constantly altered, development time is short, and the emphasis is more on the user interface. Based on continuous client feedback, the agile process paradigm entails iteratively enhancing and deploying a software system. This app is intended to make determining a person’s negligence during navigation easier and faster, while not bypassing the judge’s decision.

Nowadays, database technology keeps evolving and available on various platforms. However, the use of heterogeneous database had a limitation because each database only provides a synchronization method for similar types of databases. Therefore, the utilization of various types of databases becoming a problem since the entire data among the databases need to be integrated. Previous research had examined heterogeneous database synchronization algorithms on mobile devices using message digest. Nevertheless, this algorithm requires a longer synchronization time because necessity to check the hash value of each data record. Thus, this study investigates the development of a multi-platform database synchronization algorithm using the Entity Relationship (ER) model. This model is based on the data relationships in each table. ER model implementation is executed by creating a temporary table that stores the primary key of each data record in a table that has changed or consist new data. The synchronization process flow is determined based on the type of transaction by selecting data from the source table based on the relationship from the temporary table data to the destination database. The results of this study indicates that the proposed ER model could be a new method in the heterogeneous database synchronization process and is able to shorten the synchronization process time.

This study is devoted to analyse numerically the Saint-Venant equation. This equation is well known for solving water management problems as in assessment of water reserves using a Feed-forward network, and function management of the river system. All these phenomena are related to the unsteady flow of water in the system of rivers and canals, the flow of which is most often described by the hypothetical equation of Saint-Venant. One of the three-layer, feed-forward network framework, namely back-propagation network (BPN) is employed to represent the water resources management of Ugam river. The calculation is obtained for the motion of a river along the x-axis by using Python programming language.

Juraev 1Department of Computational Mathematics and Information Systems National University of Uzbekistan Uzbekistan Almazar 4 Tashkent Uzbekistan. 2Faculty of Ocean Engineering Technology and Informatics University Malaysia Terengganu 21030 Kuala Nerus Terengganu Malaysia.

The work is devoted to the study of the stability of the finite difference method for the initial-boundary value problem for the system of Saint-Venant equations. Easily the verifiable practical stability conditions have been obtained. Energy estimates are established for an approximate solution of a discrete initial-boundary value problem. This energy estimate allows us to assert the stability of the finite difference method. The corresponding stability theorem is proved. The discrete Lyapunov function is constructed. An a priori estimate is obtained for the numerical solution of the boundary-value difference problem. This estimate allows us to speak about the exponential stability of the numerical solution.

Previously, synthetic graphite was produced at higher heating temperature, which is above 2500°C in complex processing method and by using petroleum coke, anthracite, and coal tar pitch as the starting materials. These materials are known as non-waste sources. Therefore, in this study, Empty Fruit Bunch Waste (EFB) has been identified as a potential carbon source from waste to replace the non-waste sources of starting materials for synthetic graphite production. Hence, by implementing a controlled heating condition via pyrolysis process, with fixed heating rate and soaking time, Empty Fruit Bunch Waste (EFB), was heated at 3 different series of heating temperatures, which are, 300°C, 400°C and 500°C. The heating rate applied was maintained at 10°/min and the soaking time used 3 hours. After the heating treatment, the synthetic graphite obtained was characterized by various analytical tools, including, X-Ray Diffraction (XRD) analysis, Scanning Electron Microscope (SEM) analysis, and Fourier Transform Infra-Red (FTIR) Analysis. Based on the analysis, it was confirmed that synthetic graphite was successfully synthesized by heat treatment at 500 °C with 10°/min of heating rate and 3 hours soaking time. Synthetic graphite was observed in the form of amorphous carbon based on the XRD diffraction pattern that matches with the reference code of 00-041-1487.

Empty fruit bunch (EFB) are the second-highest waste produced in the oil palm industry which is 18 022 tonnes in a year. However, the presence of oil palm waste especially from empty fruit bunch (EFB) give a major problem to the disposal. Herein, EFB waste has been identified as a potential carbon source for synthetic graphite production. This is due to implement the lower heating temperature of synthetic graphite produced in controlled heating conditions. Several parameters have been manipulated to study the effect of various parameters on the graphitization process. Hence, in this study, the effect of soaking time towards graphitization of empty fruit bunch (EFB) waste has been investigated. EFB waste was heat treated with various soaking times which is 2 hours, 2.5 hours and 3 hours in controlled heating conditions with constant heating temperature at 500°C and heating rate at 10°/minute After heating treatment, the samples were characterized using X-ray Diffraction (XRD) and analyzed by X'Pert Highscore Plus software. The functional group of synthetic graphite was determined by using Fourier Transform Infrared spectroscopy (FTIR). The morphological study was carried out by using Scanning Electron Microscope (SEM). From the analysis, the best synthetic graphite produced is at the 2.5 hours soaking time with a constant heating temperature at 500°C and a constant heating rate at 10°/min.

Due to the advanced and hasty development of technology nowadays, researches in relation to Artificial Intelligence (AI) such as Machine Learning (ML), Genetic Algorithm (GA), Neural Network (NN) and Expert System (ES) are progressively introduced. These AI types are also frequently presented in building a new and profitable Algorithmic Trading System (ATS). Apart from Fundamental Analysis (FA), Technical Analysis (TA) based on Technical Indicators (TIs) is one of the most AI used in the development of ATS. However, there is a lack of research despite the available knowledge on TIs in ATS where AI is implemented. Therefore, this study aims to review the ATS current work comprehensively using TIs in AI. A systematic literature review (SLR) has been performed to achieve the objective of this study. This article analyses the rough and systematic literature search process for 17 selected papers from 2010 to 2020. The analysis depicts that in most published studies, GA with multiple TIs is applied. The result of this study leads to a pertinent suggestion that is aimed for further researches on ATS to be conducted by future researchers and traders.

Sediment transport prediction is essential to monitor the dynamics of a river system. The carrying capacity of a river system is greatly influenced by the deposition and aggradation of sediment particles. However, the accuracy of such predictions is subjected to various parameterization in the predictive formula. Fall velocity has been the main predictor of sediment transport prediction. The determination of fall velocity is influenced by many controlling factors such as sediment size, drag coefficient etc. Thus, selection of the best fall velocity formula is crucial for sediment transport prediction. This paper discussed the performance of various fall velocity formulas to obtain the best sediment transport prediction at the river system in Malaysia. The total bed material load formula which has been developed for Malaysian river system was utilized to test the performance of various fall velocity formulas. Seven (7) different formulas for fall velocity estimation were fitted into the total bed material load for sediment transport prediction. The best fall velocity formula was selected based on the acceptable discrepancy ratio test between the predicted total bed material load and observed total bed material load. It was found that Rubey's formula for fall velocity is best suited to be used as the predictor in the sediment transport prediction. Rubey's fall velocity formula is able to produce 56% agreement between observed and predicted values of sediment transport. Other formulas ranged from 47 - 53% agreement of the discrepancy ratio test.

Sand mining is a worldwide environmental threat that is gaining media's attention. Sand and gravel are the most important materials for building construction. However, excessive withdrawal from the river system may cause irreversible damages to the ecological and socio-economics in the long run. As demands for stronger regulation of mining develop, the scientific evidence needs to be understood in order to justify the effectiveness of the management. The mining process not only induced channel incision, but also disrupted sediment balance in the area whereas, the sediment loads responsible for the changes of the banks that lead to exposure of underlying grain, deteriorating the water quality and encroaching the abundance of species habitats. By using Quick Scoping Review (QSR), the aim for this paper is to provide a summary of various studies on the impacts practice of sand mining either positively or negatively on the environment, aquatic habitat, biodiversity and hydraulic regime of the river system. It was found that negative impacts and significant alteration were dominant opposed to the positive impacts. Channel incision, loss of habitat and sedimentation at downstream areas were identified as direct impact due to sand mining activities. QSR results show that response river ecosystem to sand mining is complex. The documented collected response showed that channel incision contributes the most impact due to sand mining activity at the river, followed by sediment fluctuation on river bed. However, self-sustaining of river to dynamic equilibrium will give little help to reduce the negative impact of sand mining activities but self-adjustment process acquires longer time than the former. These findings may help authorities on planning the best management practice for sustainable mining activities in the and nurture the importance of preserving river ecosystem and providing mitigation plan in future.
