An Analysis of Meteorological Data in Sumatra and Nearby using Agglomerative Clustering
Full text linkSumatra is one of the biggest and the second most crowded islands in Indonesia. Sumatra is also a place of abundance of tropical flora and fauna. This paper aims to cluster the cities in Sumatra and nearby based on the meteorology data. It implements Agglomerative hierarchical clustering and uses a daily time series dataset from 17 cities from 1 January 2010 to 31 December 2023. The dataset contains variables minimum temperature, maximum temperature, average temperature, humidity, sunshine duration, and average wind speed. The preprocessing data was dedicated to managing the missing values and data aggregation to create single-form data. The single-form data contains cities and meteorological variables used as an input for the clustering algorithm, i.e. K-Means, Fuzzy C-Means, K-Medoid, intelligent K-KMeans, and Agglomerative clustering. The Agglomerative clustering outperforms other methods (i.e. K-Means, Fuzzy C-Means, K-Medoid, and intelligent K-KMeans) and produces Silhouette scores of 0.11. The clusters are then analyzed to find their unique pattern. The cut-off when the number cluster is two, Agglomerative hierarchical clustering gathers Aceh, Sabang, Pekanbaru, Padang, and Padang Lawas in Cluster 1. Other cities, i.e., Nagan Raya, Batam, Jambi, Bandar Lampung, Medan, Pangkalpinang, Palembang, Bengkulu, Belitung, Tapanuli, Deli Serdang, and Nias are in Cluster 2. The results can be briefly explained that the characteristic of Cluster 1 has a higher average temperature, lower humidity, and lower sunshine duration than cities in Cluster 2. However, Cluster 1 has a lower average minimum temperature than Cluster 2. The pairs of cities which have the most similarities are (Aceh, Sabang), (Pekanbaru, Padang Lawas), (Nagan Raya, Nias), (Jambi, Palembang), (Bengkulu, Tapanuli), and (Medan, Deli Serdang). The annual trend in several cities shows that there exists an increasing trend in minimum temperature, rising sunshine duration, and decreasing wind speed. These are signs of climate change that need a proper handling
AUTONOMOUS MOBILE ROBOT MENGGUNAKAN METODE FORMAL LOGIKA TEMPORAL LINIER
Full text linkLogika temporal linier (LTL) dikontruksi dari formulasi logika tingkah laku sistem yang diharapkan dari waktu ke waktu secara linier. Dengan demikian jika pada bagian atau waktu tertentu terjadi kesalahan pada sistem, kesalahan itu dapat segera diantisipasi. Dalam hal ini penggunaan perencanaan logika temporal linier tidak hanya digunakan pada autonomous mobile robot untuk mencapai sebuah tujuan atau menghindari rintangan, tetapi juga untuk perangkaian, perluasan atau penugasan sementara (temporal ordering) pada sebuah rangkaian tugas yang berbeda dalam satu waktu. Dalam LTL untuk menghasilkan lintasan robot dilakukan tiga tahap tahap aktivitas, yaitu pendefinisan abstraksi diskrit pergerakan robot, perencanaan logika temporal menggunakan model checking, dan implementasi kontinu rencana diskret (continuous implementations of discrete plan).Pada penelitian ini, untuk membuktikan apakah model perencanaan logika temporal linier yang dibuat sebelumnya memenuhi spesifikasi tingkah laku sebuah mobile robot yang dimaksud, maka dibuatlah sebuah autonomous mobile robot sebagai alat uji implementasi formula logika temporal linier tersebut. Untuk membangun sebuah autonomous mobile robot tersebut diperlukan beberapa perangkat elektronika di antaranya mikrokontroler, sensor, kompas, dan motor penggerak. Selain itu dilakukan pula simulasi dengan perangkat lunak MOBOTSIM versi 1.0.03.Implementasi formulasi dengan simulasi menggunakan MOBOTSIM menunjukkan hasil yang lebih ideal daripada pembangunan formulasi pada robot sebenarnya Hal ini disebabkan pergerakan protipe mobile robot banyak dipengaruhi faktor luar yang dalam penelitian ini diabaikan
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
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
