Utilization Of Rubber Tire Composition For The Mechanical And Dynamic Performance Of An Energy Dissipation Damper, Ahmed Sami Hasan Al-Osta
Utilization Of Rubber Tire Composition For The Mechanical And Dynamic Performance Of An Energy Dissipation Damper, Ahmed Sami Hasan Al-Osta

Economic development results in a rise in the demand for different items, such as rubber products. Consequently, there is a continuous growth in the amount of waste rubber products generated globally each year. The waste generated from solid tires, composed of non-biodegradable substances, poses significant environmental and public health concerns. Protecting critical buildings, bridges, potentially hazardous industrial operations, and valuable equipment against earthquakes is crucial for ensuring safety and minimizing economic losses. This study aims to evaluate rubber tires' damping mechanical and dynamic properties by optimizing the rubber tire composition. Various rubber compositions were examined to determine the most efficient …

Two-stroke (2T) gasoline engine is labelled as main contributor to air pollution, especially in the city. Ironically, this engine is still being sold and used and its sales was reported to increase over the years. The reason is that 2T gasoline engine is more powerful than four-stroke engine in term of power-to-weight ratio. Advancements in 2T engines technology also produces better emissions than their four-stroke counterpart. Most 2T engines do not have oil sump for lubricant which makes the maintenance easier, cheaper, and more practical e.g., for marine outboard engine which is heavy and costly to be dismantled and brought …

In today's heavy-vehicle accidents, one of the major contributors is emergency braking, particularly for vehicles without an anti-lock braking system (ABS), which is dominant in developing countries like Malaysia. As the heavy vehicle driver applies emergency braking, there is a high chance of wheel lock-up, at which point the vehicle will skid along the road, creating braking marks from the tires. These braking marks are often used in crash reconstructions. Braking marks are mainly used by investigators to examine the vehicle's pre-impact velocity. There are many models and formulations based on kinetic energy that show the effect of some parameters. …
The Relationship Between Mental Workload And Driving Performance Of Ageing Drivers, Abd Rahman Nurul Izzah
The Relationship Between Mental Workload And Driving Performance Of Ageing Drivers, Abd Rahman Nurul Izzah
Student Works (2020-2029)
The population of ageing drivers is increasing rapidly. As ageing happened, they are exposed to disabilities due to degenerative processes, thus affecting their driving performance. For changes in driving method or design to occur, ageing drivers’ driving tasks need to be monitored, designed and tested. Comprehensive research needs to be conducted to investigate how to integrate mental workload with driving performance of ageing people. Moreover, there has been no study yet that develop a model to predict overall driving performance in Malaysia. Hence, the main objective of this study is to develop and validate a model which quantifies the mental …
Investigation Of Manual Material Handling On Musculoskeletal Disorder At Computer Numerical Control Workstation, Abdullah Nor Suliani
Investigation Of Manual Material Handling On Musculoskeletal Disorder At Computer Numerical Control Workstation, Abdullah Nor Suliani
Student Works (2020-2029)
Manual Material Handling (MMH) tasks have been recognized among the major source of work-related musculoskeletal disorder (WMSD) in automotive industry and they are commonly practiced at Computer Numerical Control (CNC) workstation. At this workstation, workers act as a material transfer device in the process of loading and unloading products from pallets to machines. The physical interaction of workers to machine is not self-chosen and workers are forced to follow the pace of running CNC machine. The worst situation happens when workers are required to operate more than one machine concurrently. The mismatch interaction between workers and machine exposes workers to …
Fatigue Damage Assessment Of Reinforced Concrete Slabs Using Integrated Dynamic Testing And Simulation, Jamadin Adiza
Fatigue Damage Assessment Of Reinforced Concrete Slabs Using Integrated Dynamic Testing And Simulation, Jamadin Adiza
Student Works (2020-2029)
Assessment of existing fatigued structures is an important aspect of civil engineering infrastructure. This is critical in most loaded civil engineering structures such as bridges that are constantly subjected to dynamic loading, causing fatigue in the materials over time. Bridge deck slabs are one of the most structural elements susceptible to different cyclic loads, requiring regular checks for damage to fatigue. In order to understand the deterioration, fatigue carrying capacity and residual strength, the serviceability of the slab under the fatigue loads was not fully explored. Therefore, this research is designed to use vibration-based techniques to investigate the integrity of …
Kinematic Analysis Of Forehand Drop Shot And Long Shot Services In Table Tennis, Ibrahim Norzuria
Kinematic Analysis Of Forehand Drop Shot And Long Shot Services In Table Tennis, Ibrahim Norzuria
Student Works (2020-2029)
Table tennis is one of the most widely played sports in the world. A frequent hand movement is compulsory to execute stroke than other limbs, especially the projection of racket and ball speeds,which can help to improve players’ performance. Until now, research on table tennis serving is limited. Service was assumed important in table tennis because the effective serve may allow the serving player to have advantage and control over the game. The 3D dynamic analysis is the appropriate method to analyze a sport activity such as table tennis. Therefore, the aim of research was to determine the kinematic involved …
Electromechanics Modelling Of The Effects Of Myocardial Infarction On Left Ventricular Remodelling, Chin Neng Leong
Electromechanics Modelling Of The Effects Of Myocardial Infarction On Left Ventricular Remodelling, Chin Neng Leong
Student Works (2020-2029)
Myocardial infarction (MI) is one of the diseases with the highest mortality rate. Following MI, myocardium experiences abrupt changes in its loading condition due to the presence of infarct. In response to such changes, myocytes undergo adaptations to maintain homeostasis. However, maladaptation can happen and lead to remodelling, in which the left ventricle (LV) gradually loses its function and eventually turns into heart failure. Nevertheless, the mechanisms underlying LV remodelling are still poorly understood. In this study, a generic LV model was developed, incorporating realistic fibre orientation and excitable contracting myocardium. It was demonstrated that the developed model is capable …
