    Nowadays, there are many new telecommunication technologies developed such as Wimax technology. Filters are essential to the operation of this technology. Interdigital bandpass filter is one of the available compact configurations. This thesis focuses on the design of multilayer bandpass filter for Wimax application. The design consist of two sets of multilayer interdigital band pass filter structures at operating frequency 2.3 GHz and provided the comparison the performance each other. These two designs have been proposed; two layers consist of four-pole and four layers for eight-pole. They were designed using CST Studio. The results showed that both filter operates well at the frequency of operation. The filters have excellent return losses of approximately -20 dB at the center frequency. From the results obtained, the fractional bandwidth for two layers and four layers is 33% and 65% respectively. In contrast, two layer inter digital band pass filters have narrower bandwidth about 0.76 GHz while four layer configurations showed that with the addition of dielectric substrates, the center frequency is shifted to 2.3 GHz and the bandwidth is broad is about 1.3 GHz

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    PENGARUH KEPALA MADRASAH SEBAGAI MOTIVATOR TERHADAP KINERJA GURU PAI DAN GURU UMUM DI PONDOK PESANTREN JABAL NUR KANDIS SIAK RIAU

    Sahrun, "Pengaruh Kepala Madrasah Sebagai Motivator Tehadap Kinerja Guru PAI dan Kinerja Guru Umum di Pondok Pesantren Jabal Nur Kandis Siak Riau", Tesis, Yogyakarta, Pascasarjana Universitas Islam Negeri (UIN) Sunan Kalijaga, 2017 Penelitian ini dilatarbelakangi adanya kesibukan kepala madrasah di Jabal Nur dengan aktivitas diluar lingkungan Pondok sehingga kurangnya perhatian,kepala madrasah terhadap kinerja para guru di lingkungan Pondok Pesantren Jabal Nur Kandis Kiak Riau karena kurangnya motivasi dari pemimpin mengakibatkan kurang maksimal kinerja guru tersebut. Kajian ini difokuskan pada 1) peran kepala madrasah dalam meningkatkan kinerja guru di Pondok Pesantren Jabal Nur 2) tingkat signifikan pengaruh kepala madrasah terhadap kinerja guru PAI di Pondok Pesantren Jabal Nur dan 3) tingkat signifikan pengaruh kepala madrasah terhadap kinerja guru umum di Pondok Pesantren Jabal Nur. Jenis penelitian ini merupakan penelitian Kuantitatif Deskriptif dengan pendekatan correlational Studiens dan reggression, serta variabel penelitian menggunakan variabel bebas (X) yaitu kepala madrasah sebagai motivator dan variabel terikat (Y) yaitu kinerja guru PAI (Y1) dan kinerja Umum (Y2)dengan pengumpulan data yang dilakukan dengan metode observasi, angket, wawancara, dan dokumentasi. Adapun uji coba instrumen dengan menggunakan Uji validitas instrumen, Uji reliabilitas instrumen, dilanjutkan ke proses analisis data dalam penelitian ini dengan analisis secara deskriptif, uji persyaratan (uji normalitas, uji linearitas), uji hipotesis (regresi linier, korelasi product moment). Hasil penelitian, menunjukkan bahwaada pengaruh motivasi yang diberikan kepala madrasah terhadap kinerja guru PAI dan guru Umum. Pertama; peran kepala madrasah di Pondok Pesantren Jabal Nur Kandis Siak Riau untuk meningkatkan kinerja guru PAI dan guru umum yang mencakup monitoring satu minggu sekali, menambah tugas dan kewajiban kepada guru yang kurang maksimal dalam menjalankan tugasnya, mengadakan musyawarah terbuka. Kedua; terdapat pengaruh signifikan antara variabel kepala madrasah sebagai motivator dengan variabel kinerja guru PAI di Pondok Pesantren Jabal Nur Kandis sebesar 39,7%. Ketiga; terdapat pengaruh signifikan antara variabel kepala madrasah sebagai motivator dengan variabel kinerja guru Umum di Pondok Pesantren Jabal Nur Kandis sebesar 11,7

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    We 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
