Design Of Formalin Use Investigation System In Food Using Android-Based Tcs34725 Color Sensor
Get PDFA system design has been made that functionsto investigate formalin in food. This tool uses a color sensor(RGB) with type TCS34725 which can be accessed throughan android phone to display the contained formalincontamination. In general, this system consists of fourparts, namely the color sensor, Arduino Nano CH340,Bluetooth HM-10, and Android. Samples tested werechicken and beef. The concentration of formalin given was0%, 2% and 5%. The data collection process was repeated15 times for each type of food sample. Indicators thatappear on the display are color. Green indicates that thesample is not contaminated, while the red color indicatesthat the sample is contaminated with formalin. Testingformalin contamination of beef and chicken meat sampleshas an accurate value of 99%
Development of an arithmetic trainer kit for understanding the concepts of Binary Addition and Subtraction
Get PDFDigital electronics is the basis of all electronic devices used today. The understanding of digital concepts, especially the concept of arithmetic (binner addition and subtraction) is very important to be applied to more complex electronic systems. The Trainer Kit has been developed as a medium and means of learning and experimenting to understand theoretical concepts for students, college students, and those who just have a hobby in the field of electronics. The stages of making a trainer kit start from system design, hardware design, system testing and implementation of the system. The test results of each arithmetic circuit block show that the system is working properly and can be used by users
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
Modification of Kenaf Fibers Composite and Empty Oil Palm Bunch With Silane Coupling Agent Addition
Get PDFThis study reports the effect of coatingSilane Coupling Agent (SCA) on composite surfaces withdifferent formulation variations of 0%, 0.25%, 0.50%,0.75%, 1% in weight fraction to the mass of kenaf fibercomposites and empty oil palm bunches using epoxy resin.Composites made from composite particulate passing 50mesh sieves. The particle board compacting process wascarried out using a Hydrolic Press compacting machinewith a pressure of 20 Bars, holding time 10 minutes in theinitial stages, and continued using a Hot Press compactingmachine with a pressure of 20 Bars, temperature 150 oC,holding time 15 minutes. The process of treating theSilane Coupling Agent solution on the composite surfaceis done manually layered on the composite surface.Composites were tested for flexibility using the UniversalTesting Machine Galdabini Gallarate referring to ASTMD 790-03 and tested for density using ASTM D 792-13.Composites in this study have fulfilled SNI 03-3527-1994type III strong class so that the kenaf composite andempty oil palm bunches can be used as an alternativereplacing wood in buildings with high densities rangingfrom 1,1 – 1,3 g/cm3
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
