ANALISIS KINERJA TEKNIK SUCCESSIVE INTERFERENCE CANCELLATION (SIC) DALAM MENGURANGI INTERFERENSI PADA NOMA
Get PDFPenelitian ini mengevaluasi kinerja sistem Non-Orthogonal Multiple Access (NOMA) yang menggunakan teknik Successive Interference Cancellation (SIC) pada kanal Additive White Gaussian Noise (AWGN). Fokus utama adalah pengaruh skema modulasi dan pembagian daya terhadap nilai Bit Error Rate (BER). Tiga jenis modulasi yang diuji adalah BPSK, QPSK, dan 16QAM, dengan berbagai konfigurasi pembagian daya (misalnya α = 0,1 dan 0,3) untuk dua pengguna dalam skenario downlink NOMA berbasis OFDM. Proses penjumlahan sinyal dilakukan di sisi pemancar, sedangkan SIC digunakan di sisi penerima untuk memisahkan sinyal dari masing-masing pengguna. Hasil simulasi menunjukkan bahwa performa BER sangat dipengaruhi oleh tingkat modulasi dan rasio pembagian daya. Modulasi tingkat rendah (seperti BPSK dan QPSK) memberikan performa yang lebih baik pada SNR rendah, terutama bagi pengguna dengan kualitas kanal yang lebih buruk. Namun, pembagian daya yang tidak tepat dapat menyebabkan kesalahan berantai dalam proses SIC, sehingga menurunkan akurasi demodulasi. Penelitian ini menekankan pentingnya pemilihan skema modulasi dan strategi pembagian daya yang adaptif dalam perancangan sistem NOMA. Temuan ini memberikan kontribusi penting bagi pengembangan sistem komunikasi nirkabel masa depan, khususnya 5G dan generasi berikutnya, yang menuntut efisiensi spektrum tinggi dan keandalan layanan multi-pengguna
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
The cyborg figure in Kazuo Ishiguro's Klara and the Sun
No full textENGLISH:
The study aims to find the depiction of the cyborg concept in the character of Klara, the main character in the novel Klara and the Sun by Kazuo Ishiguro. This research discusses 2 problems of study, that are how Klara represent the concept of Donna Haraway's Cyborg Manifesto in the novel Klara and the Sun, and how Klara is differs from the concept. The data source of this research is the novel Klara and the Sun by Kazuo Ishiguro which was published in March 2021 with Random House LLC. The method used in this research is part of literary studies using the post-humanism approach, and cyborg theory. Cyborg Manifesto is the thought of Donna Haraway who seeks to criticize and question the thought of humanism. Furthermore, the technique used by the researcher is read and classify data based on the problem of the study that has been determined by researcher. From this study, the researcher found two representations of the Cyborg Manifesto concept in the novel, First Klara as a cyborg was committed to partiality, irony, intimacy, and perversity. Second, Klara as a cyborg was oppositional, utopian, and innocent. Futhermore, the researcher also found that Klara differs from Donna Haraway's Cyborg Manifesto in two concept. First Klara's character involved dreams of a community with traditional organic family patterns without an oedipal project and the second, Klara was respected despite not remember the cosmos. The researcher suggests applying an interdisciplinary approach in future studies to explore further with different objects or theories.

Penelitian ini membahas tentang 2 rumusan masalah yakni bagaimana Klara merepresentasikan konsep Cyborg Manifesto Donna Haraway dalam novel Klara and the Sun , dan bagaimana Klara berbeda dengan konsep tersebut. Sumber data dari penelitian ini adalah novel Klara and the Sun karya Kazuo Ishiguro yang diterbitkan pada bulan Maret 2021 bersama Random House LLC. Metode yang digunakan dalam penelitian ini merupakan bagian dari studi sastra dengan menggunakan pendekatan post-humanisme, dan teori cyborg. Cyborg Manifesto merupakan pemikiran dari Donna Haraway yang berusaha mengkritik dan mempertanyakan kembali pemikiran humanisme. Selanjutnya, teknik yang digunakan peneliti adalah dengan membaca dan mengklasifikasikan data berdasarkan rumusan masalah yang telah ditentukan peneliti. Dari penelitian ini peneliti menemukan beberapa representasi konsep Cyborg Manifesto dalam novel Klara and the Sun karya Kazuo Ishiguro yakni karakter Klara berkomitmen terhadap partiality, ironi, keintiman, dan perversity. Selain itu Klara bersifat oposisi, utopis, dan innocent. Peneliti juga menemukan Klara juga merepresentasikan beberapa konsep yang berbeda dengan Cyborg Manifesto Donna Haraway yakni karakter Klara melibatkan mimpi akan sebuah komunitas dengan pola keluarga organik tradisional tanpa adanya proyek oedipal dan dari cerita peneliti menemukan bahwa Klara dihormati meskipun tidak mengingat kosmos. Peneliti menyarankan untuk menerapkan pendekatan interdisipliner atau objek yang berbeda dalam penelitian masa depan.

تهدف الدراسة إلى البحث عن تصوير مفهوم السايبورغ في شخصية كلارا، الشخصية الرئيسية في رواية كلارا والشمس لكازو إيشيغورو. يناقش هذا البحث إشكاليتين للدراسة، وهما كيفية تمثيل كلارا لمفهوم بيان السايبورغ لدونا هاراواي في رواية كلارا والشمس، وكيف تختلف كلارا عن المفهوم. مصدر بيانات هذا البحث هو رواية "كلارا والشمس" للكاتب كازو إيشيغورو التي صدرت في مارس 2021 عن دار راندوم هاوس ذ.م.م. المنهج المستخدم في هذا البحث هو جزء من الدراسات الأدبية باستخدام منهج ما بعد الإنسانية ونظرية السايبورغ. بيان سايبورج مانيفستو هو فكر دونا هاراواي التي تسعى إلى نقد فكر النزعة الإنسانية ومساءلتها. علاوة على ذلك، فإن التقنية التي استخدمتها الباحثة هي قراءة البيانات وتصنيفها بناءً على مشكلة الدراسة التي حددتها الباحثة. ومن خلال هذه الدراسة، وجد الباحث تمثلين لمفهوم بيان السايبورغ في الرواية، أولاً كلارا كسايبورغ كانت ملتزمة بالانحياز والسخرية والحميمية والانحراف. ثانيًا، كلارا كسايبورغ كانت معارضة ومثالية وبريئة. علاوةً على ذلك، وجدت الباحثة أيضًا أن كلارا تختلف عن بيان السايبورغ لدونا هاراواي في مفهومين. الأول أن شخصية كلارا كانت تنطوي على أحلام مجتمع ذي أنماط عائلية عضوية تقليدية دون مشروع أوديبي، والثاني أن كلارا كانت محترمة رغم عدم تذكرها للكون. تقترح الباحثة تطبيق نهج متعدد التخصصات في المستقب
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
