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
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
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)
Synthesis and Antifungal Activity of a Series of N-Substituted [2-(2,4-Dichlorophenyl)-3-(1,2,4-triazol-1-yl)]propylamines
No full textA series of N-mono- or N,N-disubstituted [2-(2,4-dichlorophenyl-3-(1,2,4-triazol-1-yl)]propylamines and N-[2-(2,4-dichlorophenyl-3-(1,2,4-triazol-1 -yl)propyl]amides were synthesized and tested for their fungicidal activity in vitro and in vivo against a group of plant pathogenic fungi. Some compounds exhibited a fairly good in vitro activity. The replacement of the ether group of tetraconazole with a secondary or tertiary amino group leads to compounds that maintain the antifungal activity on several phytopathogenic fungi, provided that the substituents are not too bulky or lipophilic. The allyl, propargyl, and cyclopropyl groups appear particularly suitable. Although these compounds have some structural similarities with terbinafine and naftifine, which act as squalene epoxidase inhibitors, they maintain the usual mechanism of action of the other triazoles
Use of loadbearing brickwork for three storey houses in Sri Lanka
No full textFor residential buildings, brickwork out of hand moulded burnt bricks is widely used in Sri Lanka. The majority of these buildings are single storey construction. However, in recent times, two storey residential buildings have gained popularity due to advantages such as saving in land area required and the thermal comfort that can be offered on the ground floor during the day time.
When large houses are required on small blocks of land such as 6 perch in extent, three storey residential construction can be considered as an option. This also offers further advantages since both ground and first floor are now shaded. Thus, achieving a reasonable thermal comfort in a properly planned house would be easier despite the hot humid climatic conditions prevailing in Sri Lanka.
It was shown by Jayasinghe & Attalage (1999 b) that the reduction of external surface area and the roof area of a residential building is useful for reducing the external thermal gains. Reduced external thermal gains coupled with enhanced natural ventilation can be one of the possibilities for achieving a reasonable thermal comfort. It was shown by Jayasinghe & Attalage (1999 a) that Sri Lankans can be thermally comfortable even at elevated temperatures when sufficient ventilation is available.
When three storey houses are required, the structural form generally considered is reinforced concrete frames. However, load bearing brickwork can be a cost effective alternative when the residential buildings are planned with a considerable number of partition walls and with upper floors built on top of lower floor walls.
It is shown in this report with few examples that planning of such three storey houses is practically possible. Such houses can offer a number of advantages like reduced circulation space thus leading to better usage of space, bed rooms arranged around the courtyards, study rooms located at well shaded first floors etc.
When locally available hand moulded bricks are used for construction, it is possible to
obtain a characteristic compressive strength of 1.5 N/mm2 when 1:6 cement sand mortar
is used (Jayasinghe, 1988). It is also necessary to exercise certain quality controlling
measures while selecting the bricks for construction and carrying out the actual
construction.
Since the characteristic compressive strength is limited to 1.5 N/mm2, it is necessary to
use walls of sufficient thickness for load bearing walls at lower levels. It is shown that a
wall thickness of one and a half bricks is appropriate for the ground floor and one brick
for the first floor walls. The second floor wall thicknesses should be selected with the aim of minimising the self weight, hence half a brick thick walls would be appropriate for partition walls. The external walls can be one brick thick for enhanced resistance to wind induced forces and rain water penetration.
Since openings will act as a source of weakness in load bearing walls, guidelines that can
be used for the initial layout planning stage are developed. These guidelines are also
compared with those recommended for enhanced earthquake resistance, since when new concepts are introduced, the resistance to dynamic forces could be considered as
important. The measures that can be taken to prevent cracking in such three storey
buildings are also presented along with cost effective foundation improving methods.
The cost implications of using load bearing brickwork for three storey residential
buildings were determined by carrying out a cost study. It is shown that the saving in a
house of about 200 m2 of total area could be in the range of Rs 100,000/= when compared
with the corresponding reinforced concrete framed building. Such cost savings are
extremely important for middle income earners since the bank loans are often used for
financing the house construction. Thus, it is shown that three storey residential building construction with load bearing brickwork can have many advantages such as cost effectiveness, thermal comfort, saving in land area and possibility of creating a comfortable micro climate around the house.Senate Research Gran
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
Flow behaviour of dielectric liquids in an electric field
No full textA family of 10 silicone oils with electrical conductivity similar to 10(-13) S m(-1) (a regime hitherto systematically unexplored) and viscosities ranging from 1 to 2000mPas have been Subjected to an electrical field of up to 1.5kV mm(-1) during flow from a needle. The flow behaviour of these liquids is investigated experimentally in the flow rate regime 10(-8)-10(-12) m(3) s(-1) and we analyse the results using the Ohnesorge number. Due to the low electrical conductivity and high electrical relaxation time of the silicone oils, only unsteady transient jets were found. The onset of this type of jetting has been defined using current measurements and, in contrast to conducting liquids, the non-dimensional jet diameter increases with increase in Ohnesorge number. The time elapsed between the start and finish of jetting increases with increasing Ohnesorge number
