Analysis Of The Effect Of Bx 92, Bx Ultimaxx Fuel And Their Mixtures On The Performance Of The R15 Motorcycle: Analisa Pengaruh Bahan Bakar Bx 92, Bx Ultimaxx Dan Campurannya Terhadap Unjuk Kerja Motor R15
No full textThe development of automotive technology, especially motorbikes, is increasing rapidly and. Public vehicles such as motorbikes now use a variety of fuels such as BX 92 and BX Ultimaxx fuel, vehicles that use internal combustion engines such as motorbikes have performance, namely power and torque to get maximum performance from the vehicle, one of the factors is fuel use. This research aims to determine the difference in motorbike performance when using BX 92, BX ultimatx, a mixture of BX 92 and BX Ultimaxx and a mixture of BX 92 and Ethanol with tests carried out including power, torque and specific fuel consumption tests. Testing of all variations of fuel was tested on the R 15 motorbike using testing equipment, namely the dynotest. The results of this research include power, torque and specific fuel consumption. The result of this research is that the higher the octane level, the better the results
ANALYSIS OF THE EFFECT OF BX 92, BX ULTIMAXX FUEL AND THEIR MIXTURES ON THE PERFORMANCE OF THE R15 MOTORCYCLE
Get PDFGeneral Background: With the rapid advancement of automotive technology, especially motorbikes, fuel performance has become increasingly crucial in optimizing vehicle efficiency and meeting the demands of rising motorbike usage. Specific Background: Among commonly used fuels like BX 92 and BX Ultimaxx, the performance of different fuel types and combinations on power, torque, and specific fuel consumption (SFC) remains underexplored. Knowledge Gap: While various fuels are utilized, a detailed comparative analysis of motorbike performance using different fuels and blends, including ethanol mixes, is limited, particularly in the context of octane levels and engine power. Aims: This study aims to analyze motorbike performance differences when using BX 92, BX Ultimaxx, a 50:50 blend of BX 92 and BX Ultimaxx, and an 85:15 blend of BX 92 and ethanol, assessing power, torque, and SFC on an R15 motorbike using dynotest equipment. Results: The study found that higher octane levels yield improved power and torque, with BX Ultimaxx performing best in terms of power but consuming more fuel. BX 92 proved most efficient in fuel consumption but ranked lower in performance compared to BX Ultimaxx. The BX 92-BX Ultimaxx blend showed moderate improvements in power over BX 92 alone, while the BX 92-ethanol blend exhibited the lowest performance of all fuels tested. Novelty: This study provides a novel comparative framework for evaluating mixed fuel impacts on motorbike performance, particularly in utilizing ethanol as an alternative fuel component. Implications: These findings suggest that while higher-octane fuels enhance performance, fuel blending strategies could be optimized for specific outcomes, balancing efficiency with performance, thereby contributing to more sustainable fuel use in the automotive industry
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
