Detection of scour depth using singlemode-multimode-singlemode fiber sensor / Norshazmira Mat Azmi
Get PDFThis thesis presents an experimental study in the laboratory to develop and test a method for continuously measuring and monitoring scour using Single mode-Multimode-Singlemode (SMS) sensor. The study provides an insight into the SMS technology and develops the framework using this technology to eventually address central theme in river mechanics and sediment transport; which is the scour/deposition depth around a hydraulic structure. In particular, this study develops a new packaging method for the sensor to detect the extent of local scour where a set of experiments are performed using hydraulic flume for a duration of 900 minutes with a maximum scour depth of 27 mm. The experiments presented herein are classified into two main groups, (1) the laboratory work to develop the sensor package and (2) the wavelength shift vs. the scour depth experiments. The laboratory results show that the sensor has a potential to be applied in a real-time monitoring application such as in bridge scouring. Wavelength shifts of 0.12 nm and 0.06 nm are observed at the transitions between different phases in the development of local scour around PVC pipe

The effect of waste paper sludge ash (WPSA) as cementitious material to the properties of controlled low strength material (CLSM) containing recycled concrete aggregate (RCA) / Ahmad Najmi Fakhrudeen Mat Azmi
Get PDFIt is known that the construction industry, on a daily basis, uses quite a sum of natural resources to fulfil their occupational duties. Some examples to these resources are timber, cement, aggregate and water. Most of the aforementioned materials are nonrenewable and may decrease in the near future. However, there is an alternative to ensure lower usage of natural resources and that is to reuse current waste as a construction material. Evidently, certain waste materials can be used to reduce the usage of cement altogether. Waste Paper Sludge Ash, or in short, WPSA, happens to be one of the industrial wastes that has been in demand as of late. Reason being, it can be used as a replacement for cement due to its considerable high amounts of aluminosiliceous materials. WPSA also helps in reducing several problems on disposal. This research presents the results of a parametric study on the Controlled Low Strength Material (CLSM) using WPSA from a mill plant named MNI Mentakab in the state area of Pahang. Prior to this research, it has been expected that WPSA can serve as a cementitious material substituting cement and thus reducing the exploration of natural resources. The CLSM properties that have been investigated are divided into two properties which are; plastic properties and hardened properties. In plastic properties, several tests were conducted and they are, the slump test, the flowability test, the time set, and the heat of hydration. Hardened properties on the other hand, conducted tests on the compressive test at the age 7, 14, 28, 56 and 90 days, the absorption rate and the porosity parameter. The CLSM mix was designed based on a previous study which uses a 1.3 water-cement ratio. These CLSM mixtures were casted into moulds with the size of 100 mm x 100 mm x 100 mm. Every ratio was prepared in 28 cubes with different WPSA and OPC percentages corresponding to the total of 336 specimens. The aims of this research are first, to evaluate the potential of WPSA as a cementitious material to produce CLSM containing RCA, then, to formulate an optimum mix proportion of CLSM containing WPSA as a replacement binder material and RCA, and finally, to analyse and assess the effects of WPSA to the CLSM properties containing RCA. It has been found that the best design mix that achieves all CLSM properties is on S3 which is WPSA reacts as a replacement binder material containing RC
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
