The shoreline is the boundary between land and sea. The shoreline has an irregular nature and change due to tidal conditions. Shoreline changes occur due to human activity and natural environment that results in eradication of erosion and sediment in the shoreline. UAV as a tool used to identify the shoreline change. However, the measurement of large-size reclaimed land using terrestrial survey methods, such as total station and GPS requires a huge number of efforts in terms of time and labour spending. Although, the current method is good in airborne sampling, however it is quite expensive and more complicated to handle. The objectives of this study is to identify the shoreline change from the image taken by using Unmanned Aerial Vehicle (UAV) and to analyse the data using pix4Dmapper and Global Mapper. Planning flight plans for UAV is necessary in this study. The shoreline changes are visibly clear during low tide from July to October 2018. Total length of erosion for three months from July to October 2018 is 8.428 m. Since the aim of this study was successfully achieved, using UAV photogrammetry could be applied in many fields and in determining and identifying the shoreline change.

As-built surveys are needed to record variations from original Engineering plans to what is actually built and the final set of drawings produced at the completion of a construction project. As-built surveys are required by many agencies to prove the location of a structure at a point in time. These are especially important for maintenance and future development of the site. To handle this task conventionally, total station was used, but it is more costly, time consuming and more skilled surveyors are required to conduct a total station survey. Purpose of this study is to investigate the Unmanned Aerial Vehicles (UAV) system for comparison of the proposed drawing of UTHM Pagoh Campus with the as-built orthomosaic images and to carry out the mapping based on imaged by UAV. Therefore, a method of mapping by UAV, the application of camera-equipped for visually monitoring construction and operation of buildings was used to collect all the information directly on the site which is on the study area. It is also to carry out the mapping based on imaged by UAV. The data collections show that method to earn all information required for this study is by using UAV equipment, Pix4D and Global Mapper software to generate the images. The result of the study is proved that the ability of the UAV in production of as-built survey mapping is can be achieved and it also ease the as-built survey work due to saving time and skilled surveyors are not required. Thus, UAV is very suitable for engineering work purposes

Published: June 2020

Urbanization grows rapidly in Malaysia and has known to have several negative impacts. As development intensifies, water runs rapidly into rivers and less filters through the soil, contributes to the congestion of the stormwater drainage system that leads to the flash flood problem. Waste and pollution transported by stormwater also posed environmental problems, thus several open drain systems were introduced to improve it. However, some of those open drainage systems contributes to more pollutions and worsened the quality of life of the urban dwellers in Malaysia. Several approaches with different concepts have been developed, including the Best Management Practices (BMPs), Low Impact Development (LID), Water Sensitive Urban Design (WSUD), Sustainable Urban Drainage Systems (SUDS), Innovative Stormwater Management and the Green Stormwater Infrastructure (GSI). This paper proposed the potential system that gives minimal impact to the environment while improving the water filtration and flood control system in the urban areas. The GSI system can effectively address water environment issues caused by traditional stormwater drainage systems. Research focuses on the development and application of an integrated GSI storage used in urban areas adapted to flood risk with the used of bio-composite material. A lab scale system was developed to study the performance of bio-composite materials and the design of inner storage as an infiltrator as runoff decelerator. Results showed that the used of rice husk and coconut fibre as an infiltrator improved the quality of rainwater. The integrated GSI that was designed to have an inner storage also elongates the surface runoff time. It is expected that the proposed design of eco-friendly integrated storage for drainage system could prevent ponding and at the same time the contaminated flow will be filtrated by the embedded bio-composite materials before entering the water bodies.

Published: June 2020

The moisture content and curing condition affect the compressive strength of the interlocking compressed brick (ICB). Higher strength of ICB can only be achieved when the moisture content is at the optimum level and under proper curing method. However, the moisture content of soil is varied and difficult to be identified. In addition, there is no standard of curing method was established for ICB. Therefore, this study investigates the effect of moisture content and types of curing on the compressive strength and water absorption of the ICB samples. Two (2) different moisture contents were investigated, which are the 11% and 18%. All ICB samples were cured under three (3) different curing conditions and tested for the compressive strength, water absorption and density tests. The findings showed that all ICB samples containing 18% of moisture exceeded the minimum requirement of compressive strength (7 N/mm2) based on MS76:1972. Meanwhile, ICB cured under Curing B condition has shown the highest compressive strength and lower water absorption. This indicates that sufficient moisture and proper curing method can produce good ICB brick for use in the building construction.

Abstracts

Anterior Cruciate Ligament (ACL) injury is very prevalent in the field of orthopaedics, particularly in sports. Different parameters can be used to forecast an Anterior Cruciate Ligament (ACLR) patient’s health condition. The aim of this research is to use Mahalanobis Taguchi System (MTS) methodology to identify useful biomechanical variables from multivariate parameters through Kanri Distance Calculator (KDC). This study analyzed biomechanical variables based on the knee flexion and extension moment and peak vertical ground reaction force from kinetic parameters; phase swing / stance, step and step length and gait velocity from spatial temporal parameter; range of motion from kinetic parameters. This experiment engaged 15 healthy subjects and 10 ACL reconstructed patients. Then, by optimizing the KDC, the 9 attributes are reduced to 7, which are knee flexion and extension moment, speed, step length and stance / swing phase. Key attributes such as swing time and moment of knee flexion are identified as optimal variables of impact in the population. KDC extends our understanding to the correlation of characteristics and enables individual diagnosis to be performed. Then the suitable rehabilitation protocol can be objectively suggested for quicker recovery to specific subjects.

In housing construction, concrete are materials that will be used extensively to produce a wall structure that accommodates the load. However, the problem is the cost of producing by using natural resources, as it is a major mineral is difficult to find sufficient natural aggregate supply sources since high demand. Therefore, the lack of natural aggregate and its increasing demand leads to an alternative to be developed to replace the natural aggregate. This study investigated the effect of utilization of waste clay brick in Self Compacting Concrete (SCC) on its properties and performance. The waste clay brick (WBS) was replaced as fine aggregate in SCC from 10% to 30%. As the amount of waste clay brick in SCC increases, its workability and also Ultrasonic Pulse Velocity (UPV) quality decreases while the water absorption increases. The highest average compressive strength achieved was 43.3 MPa and for splitting tensile strength was 12 MPa respectively; both at 25% of WCB replacement. All test results showed that the optimum percentage to replace waste clay brick in SCC is 25% and it has the potential to be replaced as fine aggregate in SCC.

Clay has been used as main material in fabrication of bricks however the use of waste materials in brick manufacturing has been introduced for conservation of dwindling clay resources, as well as preventing environmental and ecological damages caused by quarrying and depletion of raw materials. Bricks that available in some regions have poor quality, low compressive strength, higher water absorption and uneven surfaces Therefore in this study, rice husk ash has been utilized for the preparation of bricks in partial replacement of clay. The specimens were cast with different replacement levels of clay varying as 0%, 5%, 10%, 15%, and 20% with rice husk ash. The specimens were tested for water absorption and compressive strength accordingly to Malaysian Standard EN 1008:2010 for 2 hours. Experimental shows that excessive addition of rice husk ash has higher water absorption and low compressive strength as rice husk ash percentage increases rice husk ash characteristics predominate. The bonding between the clay particle and the rice husk ash particles is weak. By adding 10% of rice husk ash by weight is the best brick properties which 6.80 MPa of compressive strength and 16.30% of water absorption. The water absorption of RHA brick developed did not exceed 20% hence promoted to be partial replacement of clay.

t-way interaction testing is a systematic approach for exhaustive test set generation. It is a vital test planning method in software testing, which generates test sets based on interaction between parameters to cover every possible test sets combinations. t-way strategy clarifies the interaction strength between the number of parameters. However, there are some test sets combinations that should be excluded when generating the final test set as a result of invalid outputs, impossible or unwanted test sets combinations (e.g. system requirements set). These types of set combinations are known as constraint’s combinations or forbidden combinations. From existing studies, several t-way strategies have been proposed to address the test set combination problem, however, generating the optimal test set is still open research being an NP-hard problem. Therefore, this study proposed a novel hybrid artificial bee colony (HABC) t-way test set generation strategy with constraints support. The proposed approach is based on a hybrid artificial bee colony (ABC) algorithm with a particle swarm optimization (PSO) algorithm. PSO was integrated as the exploratory agent for the ABC hence the hybrid nature. The information sharing ability of PSO via the Weight Factor is used to enhance the performance of ABC. The output of the hybrid ABC is a set of promising optimal test set combinations. The results of the experiments showed that HABC outperformed and yielded better test sets than existing methods (HSS, LAHC, SA_SAT, PICT, TestCover, mATEG_SAT).

This research focusing on fatigue crack growth experiment and assessments of fatigue crack growth model. Fatigue has been considered as the most important phenomena in the engineering problems. It has been found to occur in every engineering field. Many methods were introduced to overcome fatigue problem. One of it is fatigue crack growth prediction models. Fatigue crack growth model prediction can determine the residual life of the mechanical component. Fatigue crack growth is an important parameter in engineering. It may begin from undamaged area and propagate afterwards. In this case, a mechanical component condition before an unstable crack still can be used until fatigue. With the study of fatigue crack growth, it can predict the crack life of the component and can reduce cost to repair the component. In this thesis, primary objective is to develop, test and provide computational fracture mechanics model that emphasized an uncertainties quantification for surface crack. Fracture and failure study that has been promoted by S-version finite element method is focus on the analysis of the surface-crack problem. In this project, a few limitations of the study have been implemented as to present a specific scope of the investigation. Both fatigue crack growth model is considered; Paris law model and modified Forman model. The specimen in this analysis is aluminium al 2024 T3. The effect of load on the fatigue crack growth rate is investigated on aluminium 2024 T3. It is concluded that modified Forman has a low exponent compared to the Paris law. Further the crack growth prediction based on modified Forman is lower than Paris law. Paris law only can predict the crack in the region II while modified Forman can predict the crack in region II and III. After finish setup the project based on the instruction, the project is proceeded and the data is collected. The result is analysed based on the objective by using data collected from the project. After that, conclusion is made based on the result of the project.

EEG has been largely used in both clinical and research applications. Brain computer interface (BCI) system is one of the major EEG research applications which can provide a new way of communications for special users who cannot communicate via normal pathways. This paper focuses on the development of the brain controlled wheelchair which incorporates two additional control interfaces including joystick and a remote control through an android phone. All three controls are integrated in such a way that it allows the user to change the mode of control by simply changing the state of the slide switch. This work utilizes the Neurosky Mindwave Mobile headset to capture the EEG signals through a single channel placed at the FP1 position. Eye blinks and attention levels are the key features of the captured EEG that are extracted and identified through an android application. The design also assimilates ultrasonic sensors based safety system which is capable of detecting the obstacles in all four directions to ensure the safety of the user.

Object detection, identification and classification techniques have seen many variants and improvements over past two decades. Together with Internet of Things (IoT) devices, improved computational algorithms and cloud support, real-time classification with low-cost devices has already been achieved. This paper discusses the real-time object detection and classification using Microsoft Custom Vision multi-class Machine Learning (ML) model operating at the Edge of IoT network. This paper further examines the use of virtual dockers or containers at the IoT edge devices for better security and isolation by decoupling physical hardware as well that supports multiple applications and services on a single hardware. The experiments are performed using emulated and simulated IoT devices on Microsoft Azure IoT platform for real-time object classification using Custom Vision Machine Learning (ML) models run directly from the edge device. The experimental results are further discussed to validate the model accuracy and its implementation in a future Smart City surveillance environment.

One of the needs in adopting a crowdsourcing approach in software requirement system (SRS) is to be able to perform text analytics to gain insight or knowledge from the crowd’s feedback. One of the expected text analytic tasks is to be able of analyzing the feedback automatically; such as, whether the feedback concerns about the functional requirement (FR) and non-functional requirements (NFR). To automatically do the FR and NFR identification, one can treat the problem as a text classification task. Performing automatic identification requires features (word representation) that contain sufficient information which can be used to do the identification. Thus, the types of features can be considered as an important step in performing automatic identification of FR and NFR. In this study, the RE’17 dataset challenge is used as the dataset. Using the dataset, we will like to find out the effect of word embedding against traditional features (such as bag-of-words) in NFR and FR classification. In addition, we also want to find out whether is necessary to use a complex neural classifier to obtain the best performance of NFR and FR classification. Based on the obtained results, using fastText seems to be the promising classification model since the model obtained the highest Fl-score of 92.8%.

Electrosurgery has been regarding as one of the top forms of surgical interventions. This technology allows surgical procedures to be performed with high accuracy using high-frequency energy waves in order to cut organic tissue. Although there are a lot of benefits to this form of surgery, there are also dangers that originate due to the thermal nature of the procedure. Some of these issues relate to the thermal damge that can be caused by the ESU. Thus, in order to address this issue, this research proposes to use thermal sensors that can sense and read temperature fluctuations, and then by manipulating the ESG, to control the thermal output and ultimately prevent any thermal adamage to the tissue. An experiment is performed using chicken as the main tissue and experimenting with and without the controller. The results of the experiment indicated success, and that the proposed thermal control system can regulate the power and the temperature with the use of the thermal monitoring systems it has in place. The damage observed on the tissue has been observed to be little to none.

Value management (VM) has become an accepted approach in the past decade, using tools and methods that have been ordinarily understood. VM is often subjected to time and res ource pressure. The determination of the possible critical success factors (CSFs) of VM in the building projects in developing countries is an essential matter to success these projects. This study identified 34 factors and drivers to adopt VM in the construction industry. This was achieved through qualitative approach by conducting interviews with fifteen experts with substantial years of experience in building projects. Results revealed that some new factors appeared in the Egypt context that have not existed in previous studies. These factors can aid the adoption of VM practices in the building projects in the Egypt construction industry. The findings thus represent the true reflection of the VM drivers in Egypt, and their recommendations effectively encourage the adoption of VM by Egypt and also other developing countries, as they face similar problems and need similar drivers in promoting the adoption of VM in the building industry when building projects are carried out in similar method, and style.

For shale oil and gas exploration total organic carbon (TOC) is the significant factors where TOC estimation considered as a challenges for geological engineers because direct laboratory coring analysis is costly and time consuming. Passey method and Artificial Intelligence (AI) technique have used on well logs extensively to determine TOC content. But, the prediction of Passey method is low and AI technique such as ANN, Support Vector Machine (SVM) trapped in local optima, overfitting and heavy computation work or error if the technique isn’t reasonable. In this paper, for the first time in TOC prediction we propose three feature selection-based algorithm which are Decision Tree (DT), Gradient Boosting Regressor (GBR) and Random Forest (RF) respectively. This feature selection-based algorithm select the best attributes among the input parameters for TOC content prediction. Then those best attributes works as an input for AI models for training and testing the AI models which illustrates that making a correlation between well logs and TOC content for the prediction. Specifically, 2069 core shale sample and well logging sample data of the Texas University Lands of Kansas Geologic Society were divided into 1448 training sample and 621 validating sample to evaluate the proposed AI models. This proposed AI model and feature selection-based algorithm jointly allows TOC content to be accurately and continuously predicted based on conventional well logs.
