Studi Fotogrametri Jarak Dekat Dalam Penentuan Volume Suatu Objek
Get PDFFotogrametri adalah sebuah proses untuk
memperoleh informasi metris mengenai sebuah objek melalui
pengukuran yang dibuat pada hasil foto baik dari udara
maupun dari permukaan tanah. Interpretasi foto didefinisikan
sebagai ekstraksi dari informasi kualitatif mengenai foto
udara dari sebuah objek oleh analisis visual manusia dan
evaluasi fotografi. Dalam disiplin ilmu fotogrametri
dipelajari berbagai metode untuk mengklasifikasikan dan
menginterpretasi foto udara dengan berbagai metode.
Fotogrametri jarak dekat (CRP) adalah salah satu aplikasi
fotogrametri. CRP bisa digunakan untuk pengukuran objek
dimana jarak antara titik pemotretan dan objek kurang dari
100 m. Dan biasanya juga digunakan dalam pemodelan 3D
bangunan,wahana, atau jembatan.
Pengolahan data dilakukan dengan pengambilan
gambar objek menggunakan kamera non metric, pengukuran
menggunakan Electronic Total Station (ETS) dan roll meter
yang kemudian dilakukan kalibrasi kamera menggunakan
Sotware Photomodeler Scanner untuk mendapatkan
parameter internal kamera. Kemudian melakukukan
penandaan titik pada foto sampai akhirnya pembentukan
objek 3 dimensi dan volume objek.

Photogrammetry is a process to obtain metrical
information about an object through measurements made on
the images either from the air or from the ground. Photo
interpretation is defined as the extraction of qualitative
information about the aerial photographs of an object by the
human visual analysis and evaluation of photography. In
photogrammetric disciplines studied various methods for
classifying and interpreting aerial photographs with a variety
of methods. Close range photogrammetry is a one of
photogrammetry applications. It can be used for the object
measurement that is less than 100 meters. It is also usually
used in 3D modeling of buildings, vehicles or bridges.
Data processing is done by shooting objects using
non-metric cameras, for measurement using Electronic Total
Station (ETS) and meter roll, camera calibration is performed
using Photomodeler Scanner software to get the camera's
internal parameters. Then marking points is applied on the
photo until finally the formation of three-dimensional objects
and volume objects
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
STUDI FOTOGRAMETRI JARAK DEKAT DALAM PEMODELAN 3D DAN ANALISIS VOLUME OBJEK

Interpretasi foto didefinisikan sebagai ekstraksi dari informasi kualitatif mengenai foto udara dari sebuah objek oleh analisis visual manusia dan evaluasi fotografi (Edward dan James 2004). Dalam disiplin ilmu fotogrametri dipelajari berbagai metode untuk mengklasifikasikan dan menginterpretasi foto udara dengan berbagai metode. Pengolahan data dilakukan dengan pengambilan gambar objek menggunakan kamera non metric, pengukuran menggunakan Electronic Total Station (ETS) dan roll meter yang kemudian dilakukan kalibrasi kamera menggunakan Sotware Photomodeler Scanner untuk mendapatkan parameter internal kamera. Kemudian melakukukan penandaan titik pada foto sampai akhirnya pembentukan objek 3 dimensi dan volume objek. Selanjutnya melakukan perbandingan dengan hasil pengolahan data thacymetri. Hasil penetilian ini menunjukkan bahwa data foto pada fotogrametri jarak dekat belum bisa dijadikan acuan dalam proses pembentukan 3 dimensi maupun perhitungan volumenya. Perkiraan volume pada objek lemari menggunakan metode fotogrametri jarak dekat adalah 0,903 m3 dan dengan menggunakan rol meter adalah 0,192 m3. Sementata itu, volume objek gundukan berumput menggunakan metode thacymetri adalah 162,164987 m3 dan luas adalah 30 m2
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
