Algoritma Pendeteksi Marka Jalan Berbasis Pengolahan Citra sebagai Pemandu Navigasi pada Miniatur Mobil
No full textDalam sistem transportasi telah dikembangkan kendaraan dengan sistem navigasi otomatis untuk meningkatkan keamanan dan kenyamanan dalam berkendara. Sistem tersebut mampu mengendalikan mobil agar berjalan pada rute tertentu secara otomatis(humanless). Teknologi pengolahan citra dapat diterapkan dalam hal ini. Kebanyakan penelitian tentang sistem navigasi otomatis dengan pengolahan citra menggunakan garis marka jalan sebagai pemandu navigasi. Umumnya pendeteksian marka jalan dilakukan dengan metode hough transform. Maka dari itu, Tugas Akhir ini bertujuan untuk membuat sistem navigasi otomatis menggunakan algoritma pendeteksi marka jalan dengan metode segmentasi warna dan deteksi kontur. Sehingga diharapkan mobil dapat melaju dan mempertahankan posisinya diantara dua marka jalan. Pada pengujian yang telah dilakukan sistem ini membutuhkan waktu rata-rata 0,5248 detik untuk merespon perubahan posisi marka pada citra yang ditangkap. Kemampuan navigasi yang dapat dilakukan terbatas pada besar sudut lintasan 50ͦ sampai 90ͦ derajat. Hasil sistem navigasi otomatis dalam melakukan satu kali putaran pada lintasan memiliki tingkat keberhasilan 60% pada kecepatan rata-rata 0,48 m/s dan intensitas cahaya kurang dari 145 lux.

In vehicle transportation systems have been developed with automated navigation system to enhance security and comfort in drive. The system able to control the cars to run on certain routes automatically (humanless). Image processing technology can be applied in this. Most research about automated navigation system with image processing using line marking path as a navigation guide. Generally path detection performed by hough transform method. So from that, this Final Project aims to make automated navigation system using algorithm marking road marker with method of color segmentation and contour detection. So expect cars can go and maintain their position among the two road markers. In testing that have been performed this system requires average time of 0.5248 seconds to respond to the change of roads marker position in the captured image. Navigation capabilities the forum limited large angle tracks 50 to 90 degree. Results of automated navigation system in performing one-time round on track have 60% success rate at average speed 0,48 m / s and light intensity under 145 lux
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
The Role of Psychological Capital and Readiness for Change in Rural Tourism: A Phenomenological Study
Get PDFMany villages aspire to boost their tourism industry, but numerous ones face challenges due to limited ownership of three key elements: economic assets, intellectual capital, and social capital. However, a more critical factor contributing to the development of rural tourism is Psychological Capital (PsyCap). This research aims to assess the implementation of PsyCap and the readiness for change among small and medium-sized enterprise (SME) actors, serving as the primary driving force behind rural tourism. The study employs a qualitative approach, utilizing data collection techniques such as documentary studies, observation, focus group discussions (FGDs), and interviews. The participants include five MSME actors and three coordinators of the Tourism Awareness Association (Pokdarwis) in Durensari village, Trenggalek. The data were analyzed using NVivo 12. The findings reveal that human resources, including local tourism associations and a strong sense of community unity, demonstrate positive psychological capital, contributing to the outstanding success of their tourism village despite starting with very limited financial, intellectual, and social resources. The adaptive attitudes of these participants reflect their readiness for change. Further discussion is explained in the article
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
