Visual diary as a tool for idea generation for graphic design study program / Jacqueline Sim Fei Chin
This research is to explore visual diary as a tool that allows students to express their multiple creative views and their abilities in generating ideas. This tool has been integrated as part of the selected students’ assignments and projects as a practice in the creative arts education. Many of them were taught to sketch, doodle and experiment in different drawing techniques. Nonetheless, many of them are facing the problem of lack of knowledge and understanding in the ideation process. The quantitative research design and procedures were employed in this study. A total of 35 visual diaries were selected, one each from a pool of 35 students in the graphic design program. The samples in this study were 35 (N=35) students who were enrolled to pursue the visual communication module in the first year of the graphic design program. The research was conducted at the researcher’s university, being a private institution located in Kuala Lumpur. The
main tool for data collection was an assessment rubric, namely, the Ideo assessment. The quantitative data from the Ideo assessment was analysed using descriptive statistics. From the findings, it can be concluded that through the visual diary, students have shown greater understanding in the design process and that continued efforts should be made to improve, develop, and explore ideas in using the visual diary as an instructional tool for the students’ assignments and projects
Fault-tolerant capability of star connected symmetrical six-phase induction machine with single and two isolated neutrals / Wan Noraishah Wan Abdul Munim
Traditionally, electrical machines have been designed to operate with single- or three phase power supplies. In the early stage of power electronics development, three-phase machine suffers problems such as high torque ripple due to low order harmonics during six-step switching and limited current handling capacity of the power switches. This has motivated the use of multiphase machines which is capable of mitigating the aforementioned issues. The revival of multiphase machine research is mainly motivated by the need for more reliable drive systems. The vector space decomposition (VSD) model is used for a healthy multiphase machine as the basis for control to transform the phase variables to the decoupled stationary-frame variables, which consist of flux and torque producing α-β components and loss producing x-y and zero sequence components. For normal operation, the machine is controlled by regulating the α-β current components while keeping the x-y and zero sequence components to zero. The discussed control structure become invalid when the machine suffers from fault, such as when one of the phase connection is open-circuited. However, the multiphase machine is capable to This research presents a study of fault-tolerant of star-connected symmetrical six-phase induction machine (S6-IM) by evaluating the capability of S6-IM in terms of current and voltage limits. This thesis proposes the comparison between single (1N) and two isolated neutral points (2N) considering up to three simultaneous open-circuit faults. Indirect rotor field-oriented control (IRFOC) is used to generate the α, β, x, y, 0+ and 0- reference voltages. Vector control separately regulates the torque and flux producing components of the stator current and hence requires accurate current control which can be achieved using a linear current regulation. Meanwhile, reconfiguration of the controller is minimized when transiting from pre-fault to post-fault operation based on normal decoupling transformation without changing the machine parameter. Two modes of post fault operation namely minimum loss (ML) and maximum torque (MT) are further analyzed. The maximum torque is expected to be the same as the optimal amplitude. Moreover in post-fault operation, the voltage limit analysis plays an important element for post-fault control as the voltage limit has a direct impact on the speed limit. Hence, machine voltage equations require accurate knowledge of the machine parameters, especially for the rotor time constant in IRFOC. The machine equation in the α-β frame is used to perform machine parameter estimation. The accuracy of the estimated machine parameter is crucial to determine the maximum line-to-line voltages. Hence, a test rig capable of implementing and evaluating the fault-tolerant operation of an S6-IM is developed. The simulation and experimental results obtained confirm the validity and efficiency of the most suitable proposed method for the fault-tolerant capability of star connected S6-IM with single and two isolated neutrals
The critical success factors of cloud based application implementation in construction management / Mohd Asfahani Sukiman
Design and construction are information intensive activities, involving a great number of people collaborating to produce complex, one-off developments. Whilst historically, information may have been managed and communicated using paper-based systems and verbal instructions, the integration of the supply chain, the introduction of computer aided design (CAD) and building information modelling (BIM) and the development of cloud computing application means that information communications technology (ICT) is becoming a fundamental part, not just of the design office, but also of the construction site. Cloud computing is a relatively new phenomenon in the construction industry. It allows the delivery over the 'cloud' (the internet) of a range of computing services, such as storage, databases, networking, servers, software and analytics to allow building professionals access to faster and more flexible information resources. However, the absence or lack of legal and regulatory support as well as guidelines on implementation of cloud-based application in the construction industry has become a hindrance for its adoption. In this research, the critical success factors for cloud-based application implementation are analysed, as well as its impact to project success. Through literature review, the critical success factors, the application software and tools are identified. Furthermore, a survey is conducted, to get an overall overview on the utilization of cloud-based application among construction professionals as well as on the effective critical success factors for implementation. The research then concluded the impact that cloud-based application has to project success.

The rhetorical structure and persuasive principles used in Malaysian smartphone web advertisements / Thenmalar Chandran
The aim of this study is to identify the rhetorical structure used in Malaysian smartphone web advertisements. This study also aims to identify how the principles of persuasions are realised in the Malaysian smartphone web advertisements. The five websites used for the purpose of this research were selected based on a Google Search which indicated the top five most popular and accessed websites. The first five websites that were shown and selected were www.11street.com.my, www.directd.com.my, www.satugadget.com.my, www.ipmart.com.my and www.lazada.com.my and 11street.com.my. The five smartphone models and brands were selected based on the latest International Data Corporation (IDC) Quarterly Mobile Phone Tracker which was recorded in the year 2016. The moves found in the web advertisements were identified using Bhatia’s framework for advertisements (2004) while the principles of persuasions used in the web advertisements were identified using Cialdini’s principles of persuasion (2007). The findings of this research showed that the moves in the advertisements not only serve the communicative purpose of informing and introducing the details of the smartphones to the readers but also persuade them to buy the product. It was also found out that the smartphone web advertisements have some moves that were not specified in Bhatia’s framework for advertisements (2004). In short, this study is able to add on some literature in the field of genre analysis and also enrich the framework proposed by Bhatia (2004) for a specific product
A corpus-assisted discourse analysis of the representation of the 2017 Rohingya crisis in The Daily Star / Sharufatun Nahar
There is a noteworthy lack of research on media coverage of refugees and other minority groups in South Asia. The aim of this study is to examine the discursive construction of the 2017 Rohingya Crisis and the representation of key social actors in The Daily Star, a popular Bangladeshi newspaper. The corpus contains 406 online articles reporting the Rohingya issue, published on The Daily Star’s website from August 2017 to August 2018. A mixed method combining quantitative and qualitative techniques from Corpus Linguistics and Discourse Analysis is utilized to analyze the data. Using the corpus analysis software AntConc 3.5.8, collocations, clusters, and concordances of key terms are explored in order to identify prominent discourses. Simultaneously, textual analysis is carried out on extracts using van Leeuwen’s (1996, 2008) socio-semantic network model. This work is intended to enrich studies on refugee and migration issues, besides adding to existing literature on the Rohingya. Findings show that the Rohingya are predominantly portrayed as victims, followed by representation as problems and burdens in the host country. Myanmar is mostly represented as a savage and a violator of human rights. Bangladesh is represented as a savior to the Rohingya, while at the same time being depicted as being challenged by the Rohingya presence in the country. The Rohingya crisis is simultaneously constructed as a humanitarian issue and a securitarian one. Implications are discussed and avenues for further study are suggested
School based assessment of the secondary school integrated curriculum (KBSM) of music education in Peninsular Malaysia / Lee Soo Mei @ Jake Lina Lee
The purpose of this study is to identify differences of attitude (affective, cognitive, evaluation and conation) and the perception (knowledge, satisfaction, understanding, experience and effective) of music teachers toward the School Based Assessment (SBA) of the Secondary School Integrated Curriculum (KBSM) in the lower secondary public schools in Peninsular Malaysia in terms of gender and teaching experience demography. This study also identifies the opinion of the stakeholders (education officers, examination syndicate officer, principle, parents, teachers and students) toward the implementation of SBA. The study also aims to identify the students’ musical ability and band achievement based on the Standard Performance Document provided by the Examination Syndicates of Malaysia. This study employed a mixed-method, where quantitative data was collected by the first cohort of students (n=238) from eight public lower secondary schools over Peninsular Malaysia that responded in the band-achievements based on the Standard Performance Document prepared by the Examination Syndicates of Malaysia. In this study, in-service teachers (n=29) responded via a survey instrument consisting of 51 scaled item and the data were analyzed using SPSS software. The qualitative data was collected using interviews, analysis of documents and data, transcribed and analyzed using Atlas. ti software. This study showed that majority of the respondents welcomed the implementation of SBA. However, it effectiveness depends on the emphasis on the quality assurance (monitoring, standardize, mentoring and detection). These are aligned with the desires of the National Education Philosophy of Malaysia
A semantic prosody analysis of swear words in a corpus of English songs / Hazri Shahreen Hashim
This study looks at the semantic prosody of swear words found in a corpus of English songs by looking at their collocations using a corpus software; AntConc. A total of 545 songs were chosen based on the Billboard year-end chart from 2011 to 2016 with 243,689 number of tokens and 8,139 number of word types. Word lists and concordance lines were generated from the corpus for the data analysis. The analysis on the concordance lines showed that not all swear words with negative-based meaning possessed negative semantic prosody. Despite possessing negative semantic prosody, 10 out of 15 swear words possessed neutral semantic prosody and only one word had a positive semantic prosody. In summary, this study argues that swear words are not entirely negative as perceived, rather it depends on context to be regarded as negative
Comparison of different power system resilience assessment methods / Sam Chan Jian How
Climate change has been given significant attention in recent times, calling for more ideas to address issues stemming from extreme weather events. Until climate change can be slowed down and ultimately be reversed, it is an imminent objective to find solutions for the mitigation and prevention of the effects of catastrophic weather events. History has a record of the devastation caused by such events on electrical power infrastructures. While electrical power systems have conventionally been designed and built to weather everyday conditions, confronting cataclysmic high-impact, low-probability events will require more resilient attributes. Power systems are often deemed as the backbone of the operational society, and therefore, the case calling for power infrastructures to be able to withstand critical events is a case carrying compelling weight. The concept of resilience in power systems however, has only emerged in recent times. This study therefore, aims to provide further insights into the area of power system resilience, by focusing on the aftermath of an extreme weather event and how its effects on a power system can be utilized to measure the resilience of the latter. To replicate the random behaviour of weather, windspeeds categorized based on Saffir-Simpson’s hurricane scale, were randomly generated following the concept of Monte-Carlo’s simulation technique, which would then be applied to fragility curves of distribution poles based on NESC’s distribution pole classes. The resilience of the infrastructure is then modelled and assessed by applying the 3 different resilience assessment methods. Finally, evaluations are made to compare the merits and disadvantages of each resilience assessment method
Investigation of space-charge-limited conduction mechanisms in Fe3O4-Y-FE2O3 based on SIO2/N-type SI substrate / Nik Nadia Aina Nik Zumaihan
In this work, thin films of functionalized Fe3O4-γ-Fe2O3 NPs deposited on n-type Si substrate was formed by self-assembly. The co-precipitation method was involved to synthesis the bare iron oxide NPs and the particles were altered to optimum pH 12 by using NH4OH. Iron oxide NPs were then undergone modification process with addition of 0.4 g oleic acid and 1.63 mmol functionalization 4-pentynoic acid. For electrical characterization of self-assembled 4-pentynoic acid functionalized Fe3O4-γ-Fe2O3 NPs on SiO2/n-Si substrate, the charge conduction mechanisms were quantitatively investigated and analyzed through the oxides for different heat treatment temperatures (70-300oC). In this study, the Ohm’s Law and PF emission were intensively investigated to identify the leakage current density of the tested materials using SigmaPlot based on J-E plot data provided. At the lower electric field, the leakage current due to Ohm’s law is the major sources contributing to oxide breakdown at the electrical breakdown field, EB level. On the other hand, the PF emission was identified and analyzed at the higher electric field before the electric breakdown occur. The highest EB was showed by the heat-treated sample of 150oC with values of 2.58×10-3MV/cm approximately at 10-3 A/cm2 and it obeys the Ohm’s law as the slope is near to 1. For dynamic dielectric constant (kr), the sample heated at 200oC showed promising value compared to other temperatures and acquired k-value (7.99) higher than commercial native oxide, SiO2 (3.8-3.9). However, its EB is considered low which limits its performance electrically. Besides, the heat-treated sample of 150oC demonstrated the best outcomes as the leakage current is low (10-3A/cm2), high EB (2.58×10-3MV/cm) and has kr near to k of SiO2 (3.85)
Golf director competencies, human resource management practices and customer retention within the Malaysian golf clubs / Samira Partanian
Golf is a popular sport worldwide. Many studies have described management competencies in several sport contexts and have revealed that human resource is the most common denominator for successful sports club practice. However, little work has been done to identify and explain contemporary Human Resource Management (HRM) practices of staff, including directors of golf clubs related to member retention. The purpose of this study was to examine the current level and the participants' quality perceptions in the relationship among competencies of directors, HRM practices of staff, and member retention within the Malaysian Golf Clubs to advance the causal relationships among them. It was also aimed to develop a conceptual framework and a measurement model. A survey was conducted in the Malaysian Golf Clubs using the Competencies of Golf Course Directors, Employee’s HRM Practices and Member Retention Behavior questionnaires. A total of 200 questionnaires were distributed among both staff and members who were selected randomly from 34 golf clubs. Based on the data collected and theory of Total Quality Management, a research model was developed consisting of director competencies (golf operation and client care development), member retention behavior, and HRM practices of staff. Client Care Development had a positive and significant effect (β= 0.49, p < 0.05). Golf operation competencies showed a positive effect on customer’s retention behavior (β= 0.37, P < 0.05). R2 of the current model for member retention was 0.65, which accounts for 65.4% of the reachable fitness. Higher level of both director’s competencies (Golf operation and Client Care Development) resulted in a better retention behavior of customers and a better HRM practices of staff (R2 = 0.59). The HRM mediation increased the effect of director’s competencies on the member retention. The R2 for member retention behaviors was 0.68, implying that 68% of member retention behaviors can be explained by client care development, golf operation and HRM practices. The effects of both client care development (β=0.35, p<0.05) and Golf operation competencies (β=0.474, P<0.05) on HRM practices of staff were positive and significant. This means that higher level of both director’s competencies (Client Care Development and Golf operation) will tend to achieve a better HRM practices of staff. The boot strapping results showed positive and significant effects of golf operation, (β= 0. 0.32, p < 0.05) and client care development (β= 0. 31, p < 0.05) on member retention behaviors. This indicates that the direct effects of golf operation and client care development on member retention behaviors were significant after mediation of HRM practices. The structural equation modeling was done to test the model. The model showed a desirable goodness of fit, meaning that impact of directors’ competencies, staff HRM services and customer return to the Malaysian Golf Clubs was positive and meaningful. In conclusion, directors of Golf Club in Malaysia should evolve continually to manage changes and hold several skills in Golf, technical aspects, HR, and business operations. The findings of this thesis provide golf course directors in Malaysia with important information for adequate preparation in golf management
