Forecasting Penjualan Sembako Menggunakan Metode Adaptive Neuro-Fuzzy Inference System (Studi Kasus : CV Bima Laras Khatulistiwa)
Full text linkThis study compares the performance of three fuzzy membership functions—Gaussmf, Gbellmf, and Trimf—in forecasting sales of basic commodities. The evaluation was conducted by measuring the Root Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE) on both training and testing data across various window sizes. The results indicate that the Trimf membership function provided the best performance. At a window size of 4, Trimf achieved a testing RMSE of 1.77 and a MAPE of 8.23%, outperforming Gaussmf (RMSE 2.82, MAPE 12.57%) and Gbellmf (RMSE 4.64, MAPE 17.54%). Conversely, Gaussmf and Gbellmf exhibited suboptimal performance on the testing data, particularly with larger window sizes. These findings highlight the importance of selecting the appropriate fuzzy membership function to enhance prediction accuracy. Future research could explore combinations of membership functions or other parameters to further improve forecasting performance
Rancangan Desain UI/UX Pada Website Profile PT Pelayaran Nasional Indonesia Cabang Surabaya
Full text linkPT Pelayaran Nasional Indonesia (PELNI) Surabaya branch is one of the state-owned enterprises (SOEs) engaged in the field of maritime transportation services. As part of the State-Owned Enterprises (BUMN), PT PELNI has the responsibility to provide reliable and efficient shipping services, ensuring the mobility of goods and passengers in the waters around Surabaya. With a modern fleet of ships and various shipping routes, PT PELNI Surabaya strives to make a positive contribution to the economic growth of the local and national regions through reliable and safe maritime transportation facilities. A company's profile website is commonly used as a medium to facilitate individuals seeking information about the company easily. However, the profile website for PT PELNI Surabaya is currently unavailable. This absence often leads customers to make errors, such as not knowing information related to ticket booking and payment procedures at PT PELNI Surabaya. This situation prompted the author to design and create a UI web profile prototype for PT PELNI Surabaya. The method employed in creating the UI prototype design is "Keep it Simple, Stupid." The author needs to analyze customer needs and how customers will use the product or application. The obtained data will be used to identify patterns and trends among customers, facilitating the author in designing a UI prototype with more clarity. Subsequently, after the prototype is launched, the author will evaluate user feedback to rectify and enhance any shortcomings found in the prototype. Based on the design of the UI prototype for the web profile of PT PELNI Surabaya, several crucial points were identified, such as information regarding the company's profile, details about various types of ships, including regular ships, pioneer ships, and cargo ships. Additionally, contact information and the necessary procedures for each type of shipment were included. This UI design prototype is intended to address the issues raised by the author. In the creation of the UI design, the tools used were Figma. The UI design process was facilitated by the features provided by Figma, serving as the tool for creating the UI design prototype for the web profile of PT PELNI Surabaya
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
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
