A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Improving The Quality Of The Mathematics Education: The Malaysian Experience
No full textImproving the quality of teaching and learning of mathematics has always been a major concern of
mathematics educators. The four recurring and inter-related issues often raised in the development of a
mathematics curriculum are: “What type of mathematics ought to be taught?”, “Why do we need to teach
mathematics?”, “How should mathematics curriculum be planned and arranged?” and “ How can teacher
ensure that what is transmitted to the pupils is as planned in the curriculum?”.The relatively brief history
of mathematics education in Malaysia can be said to have developed in three distinct phases. In the first
phase, the traditional approach, which emphasized mainly on basic skills (predominantly computational),
was the focus of the national syllabus. In the late 70’s, in consonance with the world-wide educational
reform, the modern mathematics program (MMP) was introduced in schools. Understanding of basic
concepts rather than attaining computational efficiency was the underlying theme of the syllabus. Finally,
in the late 80’s the mathematics curriculum was further revised. It is part of the national educational
reform that saw the introduction of the national integrated curriculum (KBSM) both at the primary and
secondary levels. This mathematics curriculum, which has undergone several minor changes periodically,
is presently implemented in schools. The curriculum also emphasizes on the importance of context in
problem solving. These three syllabi, as in any other curricular development, can be seen to have evolved
from changing perspectives on the content, psychological and pedagogical considerations in teaching and learning of mathematics. In this paper, I will trace the development of the Malaysian mathematics curriculum from the psychological, content and pedagogical perspectives in relation to the recurring issues. I will argue that the development has in many ways attempted to make mathematics more meaningful and thus friendlier for students both at the primary and secondary levels. There has been also
a marked improvement on the quality of mathematics education in Malaysi
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Indentation and compressive test of bamboo at different height sections / Siti Zaleha Nor Azlan
No full textThe investigation of mechanical properties for three bamboo species found in Malaysia namely Bambusa vulgaris (Buluh Minyak), Dendrocalamus asper (Buluh Betong) and Gigantichloa scortechinii (BuluhSemantan) were carried out. The density and moisture content of bamboo culm which are basic requirement for effective analysis of its mechanical properties were investigated. The parameter studied were hardness and compressive strength of bamboo culms along different height sections which are at top, middle and bottom internode sections. The results showed that the strength of bamboo increases with length of culm for both hardness and compressive strength. The values for hardness strength for Bambusa vulgaris are 1083.33 N/mm2(top), 1000 N/mm2 (middle) and 777.78 N/mm2 (bottom), Dendrocalamus asper with 3194.44 N/mm2 (top),2222.22 N/mm2 (middle) and 1333.33 N/mm2 (bottom) and lastly Gigantochloa scortechinii with 263.89N/mm2 (top), 250 N/mm2 (middle) and 116.68 N/mm2 (bottom). The values for compressive strength for Bambusa vulgaris are 101.70 N/mm2 (top), 60.32 N/mm2 (middle) and 30.73 N/mm2 (bottom), while Dendrocalamus asper strength are 89.27 N/mm2 (top), 73.24 N/mm2 (middle) and 40.23 N/mm2 (bottom) and lastly Gigantochloa scortechinii with its strength of 121.06 N/mm2 (top), 89.23 N/mm2 (middle) and 76.46N/mm2 (bottom). The results of compressive strength of all three species of bamboo were comparable to wood, concrete, mild steel and plastic, while the hardness strength was comparable to softwood and some hardwood .Due to the results of the investigation, it was found that bamboo that has been under-utilized in Malaysia could be used as alternative material to wood, concrete, steel and plastic in applications such as housing, construction and other engineering applications
The effect of voids on the flexural fatigue properties of carbon/epoxy composites
No full textThe role of voids in composite failures has not been well understood or been characterized. This study presents the result of an investigation aimed at examining the mechanical behaviour of unidirectional carbon fibre-reinforced polymer matrix materials as used by the wind turbine industry. The experimental program investigates the effect of the void content, different manufacturing methods, type of loading (the three-point bending vs. the four-point bending) on the static strength and fatigue life under a flexural load.The four ply unidirectional carbon/epoxy composites were manufactured using the SPRINT and prepreg manufacturing methods. Manufacturing by these methods has successfully produced the composite materials with varied void contents and the voids are found to concentrate primarily in the area where the adjacent plies meet. The SPRINT materials contain voids in the range of 1.63- 2.89% while the prepreg laminates have an average void content of 3.6% for thedebaulked laminates and 6.8% for the non-debaulked laminates. The voids in the SPRINT laminate are small and they are distributed inhomogeneously. The majority of the voids are less than 0.04 mm2 in size with a shape between a circle and an ellipse.The three point bending tests show that the flexural strength exponentially decrease as much as 6.4% for the SPRINT and 6% for the prepreg for every 1% increase of the void content. The similar void effect for both materials may be due to their similar microstructures. There is a similar effect on the increase in the void content for the flexural strength and the flexural fatigue sensitivity for both the three and four point bending tests. This means that the voids do not play any large role in the three-point bending as compared to the four point bending.The mechanism of failure is observed using the optical microscopy and the X-ray tomography of the polished edge and cross section of the area near the failure. The voids are found to interact with the cracks in both the static and fatigue failures. The image of the cross section near the failure area of the static test samples seem to suggest that the voids coalesce to each other under loading. By using the acoustic emission, it can be confirmed that a major failure occurs due to the fibre breakage. In addition, the acoustic emission results also show that the failure behaviour of the low and high void content specimens is significantly different
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Properties of close-to-convex functions and special functions / Jonathan Aaron Azlan Mosiun
No full textLet S be the class of functions of the form f(z) = z + 1P n=2 anzn that are univalent and analytic in the unit disc U = fz 2 C : jzj < 1g. Study on functions derived via geometric properties such as S_, C and K, which are subclasses of S, has been ongoing for many
decades and has been done extensively and exhaustively. Among the many subclasses
of K, Sakaguchi introduced the class of starlike functions with respect to symmetric
point, denoted by S_
s . Since its introduction in 1959, many authors have introduced
generalizations of S_
s or classes resembling it. Inspired by this, Gao & Zhou introduced
another subclass of K which was denoted as Ks which was further generalized by Wang,
Gao, & Yuan. Following their inspirations, this dissertation introduces a subclass of
close-to-convex functions, denoted by Kk;N
s , where k;N 2 N, that combines the concepts
of S_ s and Ks and investigates them for their properties which include, but not limited to,
coefficient estimates, distortion and growth theorems, and radius of convexity. Moreover,
we also introduce the class of p-valent functions, denoted by Kk;N
s;p , in this dissertation which further generalizes the class Kk;N s and investigate it for its properties. In addition to investigating properties of geometric functions, many other mathematicians have also
expressed interest in finding sufficient conditions such that certain special functions has
certain geometric properties, such as univalency, starlikeness or convexity. Examples
of special functions that have undergone this investigation include Bessel and Struve
functions. Motivated by this, this dissertation also investigates sufficient conditions for
the function Tp;b;c(z) = (f _ gp;b;c)(z), a convolution between f(z) = z +
1P n=2 anzn and gp;b;c(z) = z + 1P
n=2
Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
