Passengers preference and satisfaction of public transport in Malaysia
No full textNowadays, Malaysia facing with an explosive growth in vehicle ownership and utilization, which led to traffic congestion and pollution. In this situation, government policy encourages people to use public transportation. However, Malaysia are prefer to use private vehicle become many reasons including bad quality of services. In this regard, public transport operators are forced to place emphasis on the monitoring and improvements of the services provided. This study focuses on traveler’s satisfaction and preference towards public transport with service quality attributes. Self rate questionnaire was used to investigate overall customer satisfaction and factor that influence public transport users’ satisfaction. A survey was conducted on an actual public transportation network in Kuala Lumpur, Malaysia. The aim was to evaluate the parameters in passenger preference and satisfaction on public transportation network using statistical model included variable such as facilities, comfortness and quality of services. Data were analyzed using descriptive, correlation, factor and multiple regression analysis. Result show that influences of satisfaction parameters are more than preference parameters. The application of this study suggest that the public transport operation especially buses must improve their quality of services to the prospect passengers
Ballistic performance of the steel-aluminium metal laminate panel for armoured vehicle
No full textThis paper presents the ballistic performance of the joining lightweight metal laminated panel consists of high strength steel and aluminium alloy for armoured vehicle application. Composite laminates trend in military industry present excellent performance in terms of lightweight material due to the improvement vehicle manoeuvrability, without sacrificing the performance and safety. The combination of aluminium plate and high strength steel offer the good potential for reducing the vehicle weight and improving the ballistic resistance. Ar500 and Al7075-T6 were chosen in designing laminated panel to achieve intended 20-30% weight reduction. Joining between these two materials have been investigated using both brazing method and adhesive bonding method. The adhesive bonding involved two types of material which is epoxy and polyurethane. Mechanical tests such as bending tests, drop weight tests and ballistic tests were performed to assess the strength of the laminated panel. Results showed that polyurethane bonded laminate panel through adhesion process exhibited 75% higher strength that that through the brazing process after performing impact test. Meanwhile, the penetration patterns found numerically are nearly similar to that from the ballistic tests and thus has validated the finite element models developed. The study on application of this laminated plate shall be extended using higher level of threat for hard armour vehicle panel
Analisis data rawak terikan-lesu menggunakan kaedah statistik purata-tergerak
No full textKajian ini dijalankan untuk menganalisis data terikan-lesu yang diukur pada sistem ampaian sebuah kereta. Oleh itu, teknik ini diperkenalkan bagi menganalisis kebarangkalian serta mendasari data yang berkaitan dengan beban terikan-lesu. Dalam analisis lesu bahan dan komponen, kerosakan lesu biasanya disebabkan oleh kesan daripada satu pembolehubah rawak, yang biasanya dibentuk daripada satu set data siri-masa. Menerusi data siri-masa ini, kajian data lesu dapat diperkembangkan menerusi kaedah statistik dan model analisis yang dicadangkan ialah model purata-tergerak. Model ini dapat menganggarkan trend purata-tergerak bagi mengurangkan variasi rawak dalam suatu data. Dalam kajian ini, data terikan-lesu telah diperolehi daripada pengukuran ke atas komponen sistem ampaian kereta yang dipandu di atas permukaan jalanraya luar kawasan perbandaran. Data ini diukur pada frekuensi persampelan 200 Hz dalam tempoh 300 saat. Kemudian, data ini telah dilakukan analisis purata-tergerak menerusi kaedah Peratusan Ralat Min Mutlak (MAPE), Sisihan Min Mutlak (MAD) dan Sisihan Min Kuasa Dua (MSD). Analisis korelasi data berdasarkan kepada Fungsi Autokorelasi (ACF) dan Fungsi Separa Autokorelasi (PACF) juga dibincangkan. Secara kesimpulannya, dapat dirumuskan bahawa kaedah-kaedah ini dapat digunakan untuk memproses data rawak yang berubah-ubah bagi penghasilan satu data yang pegun, dengan menyingkirkan bahagian-bahagian data yang tidak pegun
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
