Chapter 4. Hybrid Composite Fiberglass Structure with Embedded Aluminum Phosphate New Fire Retardants Additive: Effect of Fiberglass Types

Composite fiberglass is a common material used in marine industry to fabricate marine sport equipment, boats, yachts and others. The material is expected to have a performance such as high strength, economic and safety especially related to fire incidents. However, in composite fiberglass, the resin in the system has high flammability properties and becomes the acceleration factor of fire propagation after ignition. The current system is a combination of ATH and APP and produces optimum fire-retardant performance. The mixture with a fire-retardant additive leads to an extra procedure and risk to the mechanical properties of the structure. Thus, this study is conducted to evaluate the mechanical and fire retardants performance of various hybrid multilayer fiberglass composites embedded with aluminum phosphate (0 wt%, 5 wt%, 10 wt%), a new fire-retardant additive. The highest mechanical strength was observed in samples with in all samples with 5wt% of aluminum phosphate additive. A combination layer of CSM, WR and CSM shows the optimum result for mechanical strength and fire-retardant properties.

Chapter 9. Analysis on Wave Generation and Hull: Modification for Fishing Vessels

This paper analyses the fishing vessel design in terms of wave generation and hull modification. The objective is to distinguish the fishing vessel designs between an existing hull and a modified one. This is then used for simulation via a CFD software to determine the better layout. The design is created in the Autodesk Inventor software based on the vessel particulars from the designated design. These designs are then transferred to the Flow3D software for the result. The configuration is done via a multi-block feature. Based on the literature, the deep V hull is proven to be more advantageous in rough conditions as it is more efficiently operational at a preferred velocity as opposed to the round bottom hull. The successful simulation outcome of this study is influenced by the different total number of mesh elements. The distinct sum of mesh elements impact on precision of the outcome, simulation outcome, mesh execution and resolution is achieved. Several suggestions are recommended on ways to run a CFD simulation successfully.

Chapter 10. Technical Vocational Education Training Pathway for Post-secondary Autistic Students in Malaysia

The Malaysian Ministry of Education aims for 75% of children with special needs to be enrolled in inclusive programmes by 2025 which are specially designed for autistic children aged 5–17. However, this rehabilitation programme is disadvantageous to a certain extent as it only caters for children below 18 years old with no clear post-secondary educational pathway for autistic learners between the ages of 18–25. The significantly growing number of children suffering from learning deficits such as those with autism spectrum disorder (ASD) is now globally researched with more importance being given to addressing this issue in countries around the world [1]. The number of children in special needs programmes has also increased greatly between 2006 and 2013 in Malaysia. Mentally challenged individuals are unique as they have skill sets that are valuable for their well-being and society at large. This awareness justifies their inclusive development movement and global efforts. Malaysia needs a clearer path for post-secondary technical vocational educational training (TVET) for autistic learners in Malaysia as an alternative to the purely academic-based education. This review of related literature in the TVET setting for the autistics will provide a deeper understanding of the needs of our autistic youths to ensure that they are not sidelined in their pursuit of higher education.

Chapter 11. Maritime Students’ Perception of Mental Wellness

Students at the tertiary institutions are commonly faced with numerous phases of transition and challenges. University life may present young students with multiple stress factors linked to transitional effects from high school to a new environment. Literature has proven numerous symptoms indicating common mental and psychological health problems such as stress, anxiety and depression experienced by tertiary students. One’s psychological state may influence his/her perception about life. Adolescent wellness comprising that of the university students is a research area that is gaining an increased focus on. Being adolescents, these students are bound to undergo a critical stage of psychological and biological transformations which are normally influenced by the continuation or adoption of health-related behaviours. Nevertheless, a thorough analysis of the present literature reveals the dearth of coverage on adolescents’ perspectives on the definition of wellness. This research is thus aimed at investigating the perception of a group of maritime bachelor’s degree students in the northern part of Malaysia regarding their mental health and well-being as university students. A survey questionnaire was distributed to 90 undergraduates at a maritime university in northern Malaysia. By exploring the undergraduates’ understanding of the concepts of mental health and mental well-being, they can be guided to seek assistance for handling difficulties related to their well-being.

Chapter 12. Optimization of Route Selection and Carbon Emission Release for Waste Collection Systems

In general, transportation is important to any industry in the world that involves the movement of goods from one destination to another. In waste collection systems, the movement of waste collectors using transportation is one of the main activities in handling waste management today. The activity of collecting waste involves the waste generated by the residential area, industrial area, and port area that consists of many types of waste such as domestic waste, food waste, plastics, industrials waste, metals, and waste that is generated by the manufacturing processes. Then by choosing the best route for collecting waste which is to define the shortest way that merges with the time of operation will reduce the operational cost of the company and at same time reducing the quantity of carbon emission release that impacts the environment. Thus, this research is a preliminary study to analyze the actual route that is usually selected and used by truck drivers by using optimization method called the traveling salesman problem (TSP) method. This method is used as a tool to decide the optional route for collecting waste by Majlis Perbandaran Manjung (Sitiawan district) to collect the waste generated by the Sitiawan residential area and Kg Acheh industrial area to the final destination which is located at Segari Landfill. The final result shows that by optimizing the routes selection, the suggested routes will show a lower distance of about 28.3% (29.18 km) and release only 15.95 kg Co2 of carbon emission. The result shows a slightly significance and benefit to the company in reducing the cost of operations and time-consuming without underlook on the environmental aspect. However, this result depends on several variables that need to be considered such as the rest time, road closure, number of traffic lights, congestion, accident, peak time, and current situation during the process of collecting the data. All of these variables are different for any location and number of vehicle in one time.

Chapter 13. A Design of a Dielectric Resonator Antenna for Higher-Order Mode in the Shape of Rectangle for 5G Application

In this paper, the rectangular-shaped dielectric resonator antenna (DRA) operating on higher-order mode for the fifth generation (5G) communication applications is designed and presented. The millimeter-wave band was considered as a potential carrier frequency that is important to be one of the 5G technologies. The millimeter-wave band around 20–300 GHz was chosen to offer a large bandwidth, high gain, and minimum size to support higher data transmission in wireless communication. The proposed DR antenna is excited by using a microstrip feed line and designed at the operating frequency of 28 GHz. The Rogers RT/Duroid 5880 material having a thickness of 0.254 mm and a dielectric constant of 2.2 is used for the substrate. The commercial CST microwave studio (CST MWS) software is used for the optimization and simulation of the antenna design. In this research, the result is based on different dimension of the rectangular-shaped antenna by decreasing 2.9% and 1.1% the value of height and width respectively, but the value length is increased about 3.6% from the benchmark antenna design. The results indicate that the proposed antenna design produced a better performance about in the range of 1.5% to 7.2% in regard to return loss, bandwidth VSWR, gain, and directivity. Thus, the proposed antenna design is suitable for future 5G wireless communication applications.

Chapter 14. Development of a Solar Tracker Using Servo Motor and Light Dependent Resistor for Electrical Boats

Solar power is one of the natural sources available in most countries. This gives a definite advantage to the tropical countries that experience hot weather to use solar energy to generate electrical power supply. However, the generation of electricity using solar irradiation is costly and it can produce its maximum capability only at peak hours which is 12 pm to 3 pm in a day. In order to overcome this disadvantage, researcher has developed a mechanism called the solar tracker. The solar tracker will track or trace the position of the sun from the morning until evening and manoeuver accordingly to get maximum exposure. By doing so, the solar panel can obtain its maximum capability in the morning and evening although the time is not in peak hour. A solar tracker can also increase the solar output from 5% to 20% depending on the tracker and weather. This project extends the development of the solar tracker by building a portable solar tracker by using a servo motor and a light-dependent resistor (LDR). The average voltage, current, and power output between this solar tracker and a fixed solar panel show more than 50% improvement. The percentage of the output between these two panels has been calculated to show the rate of improvement.

Chapter 15. Barnacles Growth Monitoring at KL Paus Hull Using Scilab Programming

The aim of this research is to monitor the growth of barnacle at the KL Paus hull vessel part using Scilab programming (image processing). Barnacles paste on the hull of a ship might effect the resistance of the vessel, increase friction and can reduce the vessel’s speed. The ship must then be put in a dry dock to have the bottom scraped. From the results, it is shown that barnacle grew drastically for three consecutive months and the analysis form the Scilab Blob analysis found the indicated grey, dark and red intensity with true pixel increased by 30%. The edge detection image was also able to find the starting of the barnacle growth with small size. The monitoring of the barnacles is difficult if no proper instrument and analysis processes are used. It is now commonly accepted that using computers simulation and data analysis have become widespread throughout differences areas of engineering applications. By using the Scilab software, we analysed the photos of barnacle growth that were taken frequently for 3 months.

Chapter 16. Mitigating Engine Exhaust Emission Using Solenoid as Replacement for the Engine’s Block

The emissions produced by hydrocarbon engines are one of the main sources to air pollution and climate change. In order to mitigate those problems, the emission produced by the engine can be eliminated by replacing the fuel in the engine’s block with solenoid. The model operates on solenoid with various speed settings of the engine. No emission was generated during the operation and the combustion-related part of the engine are removed, thus, reducing the overall weight of the engine. Waste heat is dissipated at the power transistor, solenoid, and piston due to losses such as ohmic resistance and eddy current. Due to nature of the solenoid which is similar to an inductor, this engine is expected to best operate as low-speed engine.

Chapter 19. On the Hydropower Energy Generation from Pipelines

The primary objective of this study is to analyse the electrical power output generated from water flow in pipelines by using a suitable method to carry out the experiment. Hydroelectric power generation is widely used in Malaysian to generate electricity for consumer. As it comes with the function of a dam that collects water and the water flows from high level to low level that passes through turbine to generate electricity based on their capacity. For ship usage itself, the electricity is generated using diesel generators. If one applies the principle of hydroelectric power generation on ship, one can reduce the fuel consumption and dependency toward the generator. As pipelines are widely used in ship systems, there is always pressure in it no matter type of fluid in it. Moreover, only little alteration must be made to the system when applied by ship owners. The system consists of a turbine inside the pipeline connected to the shaft that rotates the rotor to generate electricity that can be stored using batteries or distributed for ship usage.

Chapter 21. Green Port Indicators: A Review

Unlike the shipping sector that has witnessed concerted international efforts to address sub-standard ships, similar action has not been seen in the port sector. Other than the efforts taken by the European Sea Ports Organisation that has produced various environmental guidelines to seaports located in the European Union, most efforts to become green or environmentally sustainable are arguably unilateral in nature. As interest in ensuring greener shipping began to accelerate after the implementation of Annex VI of the International Maritime Organization’s MARPOL Convention in 2003, the interest to extend its effect on greener seaports has begun to be seen. This resulted in an increase on green port studies beginning 2010. Therefore, the aim of this paper is to review the accessible literature on green ports and to identify the indicators or determinants that were normally addressed to ensure their green performance. Literature search was done through the google scholar search engine using the keywords “green port” and “sustainable port” to identify the relevant literature. Subsequently, a qualitative content analysis technique was used on the 27 identified articles in order to merge the various findings into suitable categories.

Chapter 23. An Improved Simple Sweep Line Algorithm for Delaunay Refinement Triangulation

This paper is focused on simple sweep line algorithms with Delaunay refinement triangulation to create 2D triangulation. A new algorithm is proposed where the main idea is to add circumcircle properties into the simple sweep line algorithm. Since the Delaunay triangulation itself still generates poor quality of triangles, this paper applies the Delaunay refinement to enhance the triangulation. Next, this paper observes the percentage of bad angles to analyze the quality of the triangles and the flipping number required for each set of points to analyze the efficiency of the algorithm. At the end of this research, all objectives are achieved where an improved simple sweep line algorithm with Delaunay refinement triangulation is obtained.

Chapter 24. The Effect of Increasing Travel Speed at Constant Rotational Speed on the Formation of Friction Stir Welded AA5083 Butt Joints

In order to find out the optimum input in terms of travel speed, the experiment was conducted by having a constant rotational speed with the increment of travel speed. These variables were selected based on the pre-setting speed available on a universal milling machine of Milko 37. Different welded specimens were produced by employing travel speeds of 29, 44, 54, 67, 86 mm/min, and constant rotational speed of 910 rpm. The tilt angle of tool at 3°, tool shoulder diameter of 20 mm, and threaded cylindrical tool pin were utilized in this experiment setting. With the increment of travel speed at a constant rotational speed (RPM), varying contact conditions at the material interfaces were created. The result obtained for this research were taken from visual analysis on surface and cross section of every joint. Based on this result, the optimum travel speed for constant rotational speed (910 rpm) is 29 mm/min.

Chapter 28. Optimization of Welding Parameters for Self-Support Friction Stir Welding (SS-FSW) on AA6063 Pipe Joints

The use of the friction stir welding (FSW) process with the needs of inner mandrels or backing plates will limit the further application for industrial needs. Therefore, the self-support friction stir welding (SS-FSW) technique is used to run the joining process without the inner mandrel or backing support especially for pipes. In order to execute the experiment, the AA6063 pipe with 89 mm of outside diameter and 5 mm of wall thickness was utilized in this experiment setting. Several edge preparations were used such as butt, scarf and stepped joint. In addition, the different pin profiles were also used: cylindrical, rectangular and triangular shape. The selected rotational speeds were 910 rpm, 1280 rpm and 1700 rpm. The Taguchi L9 orthogonal array was used to minimize the number of experiments as it is difficult to conduct a high number of experiments to find out the level combinations. The height of deformation was measured and analyzed further by the use of a statistical tool, i.e. analysis of variance (ANOVA) via Minitab 19. As a result, the optimum parameters were 910 rpm of rotational speed, rectangular pin profile and stepped joint of edge preparation, with the minimum height of deformation at 542.25 μm. The pin profiles were the major factor that can affect the output with a 62.38% of contribution. The future works will be continued until the elimination of the requirement of inner mandrel or backing plate in the use of FSW process can be achieved.

Chapter 31. Lane Detection Using Image Processing for Driving Assistance

The number of traffic accidents and injuries continues to increase year by year which causes loss of life and assets. The key facts from the World Health Organization (WHO), approximately 1.35 million people die each year as a result of road traffic crashes. Under this condition, to reduce the number of deadly accidents, the lane detection system is applied in an autonomous vehicle to increase the vehicle safety and passenger safety. The lane detection is one of the computer vision-based systems for driver assistance, as it uses an existing lane marking where the image is captured by the onboard camera mounted in the rear-view mirror facing the front of the vehicle. The proposed algorithm that has been created can detect a lane marking under variable condition of the road such as in the case of urban roads or highways with different printed marks as solid or dashed lines. Furthermore, the algorithm is designed for real-time applications.
