Corak pencapaian pelajar kumpulan pertama sistem pendidikan berasaskan hasil Fakulti Kejuruteraan Universiti Kebangsaan Malaysia
No full textSelaras dengan keperluan Lembaga Jurutera Malaysia dan Kementerian Pengajian Tinggi Malaysia, pada sesi akademik 2005/2006, Fakulti Kejuruteraan UKM telah mula melaksanakan pendekatan kurikulum pengajian prasiswazahnya kepada Pendidikan Berasaskan Hasil (PBH) yang melibatkan perubahan pendekatan pengajaran serta silibus beberapa kursus tahun pertama dan kedua. Satu jawatan kuasa telah ditubuhkan di peringkat fakulti bertujuan memantau secara berterusan perjalanan dan keberkesanan usaha ini. Kertas kerja ini menerangkan salah satu hasil kajian yang dijalankan, iaitu mengenai corak pencapaian PNGS pelajar yang telah mengikuti kurikulum baru ini selama empat semester. Kajian ini melibatkan 391 pelajar tahun 2 sesi akademik 2006/2007. Pelajar dibahagikan berdasarkan jabatan, jantina dan PNGK kemasukan yang terbahagi kepada Pelajar dibahagi kepada 1)lepasan Matrikulasi Kementerian Pelajaran, 2)lepasan STPM, 3)lepasan Kes Khas Sains, dan 4)lepasan Kes Khas. Antara hasil kajian yang menarik ialah pelajar perempuan mendapat pencapaian yang lebih baik dari pelajar lelaki untuk 2 tahun pertama pengajian
Performance test of solar assisted solid desiccant dryer
Full text linkThe solar assisted solid desiccant dryer was designed and developed to dry agricultural product. The experiment was carried out to study the performance of the component in the dryer system and drying air condition without load. The system can produce drying air at average temperature 52oC under average solar radiation of 797 W/m2 which is suitable for heat sensitive product to maintain the fresh color, taste and nutrient content. The collector efficiency, heat exchanger effectiveness 1 and 2 was 70%, 77% and 67%, respectively. The thermal, regeneration and dehumidification effectiveness was 48%, 29% and 6%, respectively. The poor
performance of desiccant wheel may be improved by increasing the regeneration temperature above 65oC. Some improvements are still required to improve the overall performance of the system such as decrease the regeneration air flow rate, increase electrical heater power and using direct connection from the solar collector to the dryer system
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
Automatic Recognition System for Pejibaye palm DNA using SVM
No full textThis paper account for a correct DNA simplified sound, and inexpensive parameterization of pejibaye palm races, and a SVM automatic correct classifier obtaining 100% classes identification. The biochemical proposed parameterization, based on 89 RAPD primer markers applied on haplotypes of pejibaye races, has been proved correct by the classifier rate success. Previous result leads to a substantial description reduction over the DNA total chain description. Finally the interesting combination of this techniques (biochemical and computational), gives rise to a formulation of an inexpensive and handy method of origin denomination plant certification.266262Editors: Azami Zaharim, Nikos Mastorakis, Ioannis Gonos
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
