PREDIKSI KERUSAKAN KINERJA STRUKTUR BANGUNAN GEDUNG MENGGUNAKAN JARINGAN SARAF TIRUAN DENGAN METODE PURELIN
Full text linkAn earthquake is one of the natural events whose magnitude cannot be predicted. This is can happen because the direction of the earthquake work depends on the movement of the soil that supports it. This is generally the biggest threat to construction, especially buildings. Buildings are expected to be built because they can use even a small area of land. However, over time, it is common for buildings to collapse due to earthquakes, so a more detailed analysis is needed to design a better earthquake-resistant building. Time history analysis is one of the analyzes used to evaluate buildings against earthquakes. However, time history analysis has a weakness, namely the duration of the analysis tends to be long, so determining whether a structure is still able to function according to plan is difficult to measure. Analysis of artificial neural networks by utilizing structural response data is expected to be able to predict the structural performance of building structures. The purelin method reads data linearly but in this case, predicts based on previous data or is known as the Backpropagation Analysis method
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
STUDI PERBANDINGAN NILAI BEBAN DAN LENDUTAN EKSPERIMENTAL BALOK BETON BERTULANG DENGAN TAMBAHAN SIKACIM COCRETE ADDITIVE MENGGUNAKAN ABAQUS CAE
No full textEffective testing of concrete structures in the field requires a lot of precision and understanding the response and behavior of loads, namely the comparison between experimental test results of reinforced concrete beams and the results of analysis in the CAE abaqus software. The abaqus CAE software is a modeling application that belongs to the Finite Element. Concrete with high quality is quite difficult to work. Therefore, the chemical Sikacim Concrete Additive is added to make work easier and maintain the quality of the concrete. This research will be a recommendation on the reinforcement placement arrangement that can increase the load value of the test object. Modeling reinforced concrete beams in the abaqus application for this study is expected to get results close to experimental tests in the field. The result with the addition of Sikacim Concrete Additive of 1% by weight of cement to the compressive strength of concrete has increased from normal concrete, namely from 25.81 MPa to 28.98 MPa. The results of flexure testing of reinforced concrete beams in the field obtained a maximum load value of 123.18 KN with a deflection of 1,07 cm. While the modeling of reinforced concrete beams in the abaqus application obtained a maximum load value of 155,738 KN with a deflection of 0.565Â cm. the deflection of these 2 variations is a better recommendation compared to field testing and abaqus modeling without variations. The deflection in variation 1 is 0.485 cm with a load of 155.73 KN and variation 2 is 0.413 cm with a load of 178.477 KN

No full textEffective field testing of concrete structures requires a great deal of rigor and understanding the response and behavior to concrete loads. The bending of the beam tends to be smaller, so reinforcing steel is used to increase the displacement of the beam. However, errors often occur in the implementation so that there is often a decrease in the quality of the concrete. The arrangement of the reinforcement is not in accordance with the requirements for the load received, so it is necessary to create a model according to the load to be applied without conducting multiple trials (trial errors). The abaqus CAE software is a modeling application that belongs to the Finite Element. Modeling reinforced concrete beams in the abaqus application for this study is expected to get results close to experimental tests in the field. namely the comparison between experimental test results of reinforced concrete beams with the results of analysis in the abaqus CAE software. The results of flexure testing of reinforced concrete beams in the field obtained a maximum load value of 106.22 KN with a deflection of 1.126 mm. While the modeling of reinforced concrete beams in the abaqus application obtained a maximum load value of 146.203 KN with a deflection of 4.83 mm
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
