Pemanfaatan Teknologi Pound Untuk Pemerataan Beban Server Web

Akses webmerupakan layanan yang banyak disediakan pada jaringan Internet. Beban serverbisa sangat tinggi pada saat diakses pengguna yang sangat banyak dan secara serentak. Salah satu cara yang dilakukan supaya serverdapat melayani akses tinggi adalah penggunaan beberapa server. Beban akses didistribusikan pada beberapa server. Penelitian bertujuan untuk menerapkan pemerataan beban, menyusun metode untuk mengamati beban serverdan menganalisis pembagian beban akses terhadap serverselama kurun waktu tertentu. Beban serverdidistribusikan pada beberapa servermenggunakan teknik pemerataan beban. Proses pemerataan beban dilakukan oleh perangkat lunak Pound. Layanan akses webdilakukan oleh perangkat lunak Apache. Metode penelitian dilakukan dengan pengamatan terhadap jumlah akses yang diterima oleh server. Pengamatan akses webdilakukan selama enam bulan. Hasil pencatatan akses webdiolah untuk menentukan beda beban akses yang diterima serverweb. Hasil penelitian yang diolah berdasarkan akses harian, mingguan dan bulanan menunjukkan bahwa perangkat lunak Pound dapat berfungsi secara baik untuk pemerataan beban serverweb. Beban akses serverwebditemukan agak kurang terbagi merata dengan perbedaan jumlah akses harian sebesar 5,5%. Akses mingguan dan akses bulanan menghasilkan angka perbedaan sebesar 3,18%. Peda penelitian ditemukan ada sedikit perbedaan hasil akses harian, mingguan dan bulanan yang disebabkan karena adanya gangguan pada salah satu serverpada tanggal tertent

Upowszechnianie wyników badań naukowych w międzynarodowych bazach danych : analiza biometryczna na przykładzie nauk technicznych, ze szczególnym uwzględnieniem elektrotechniki

The issues of bibliometrics, scientometrics, informetrics and webometrics have an important place among research subject undertaken by Polish and foreign scholars. Initially, these notions were used only by researchers in the fields of library science, scientometrics and information science. However, at the turn of the 20th and 21st centuries, quantitative methods became a fundamental tool for evaluation of, among others, sources of academic communication, academic research, research and academic centers. One of the elements of the evaluation is a quantitative analysis of academic publications in databases with international access. It is of particular importance in the case of technical sciences. This work is an attempt at a quantitative analysis of publications by Polish authors (affiliated to Polish technical universities) and Polish journals on electrotechnics in international databases. The contents are organized into four chapters with an introduction, conclusions, bibliography, name index and a list of figures and illustrations. Chapters one and two are devoted to theoretical issues, whereas chapters three and four – to practical issues. In the first chapter, selected issues concerning quantitative methods were presented, including an analysis of literature and a discussion over terminology carried out in book publications and journals. Moreover, selected examples of research conducted with the use of quantitative methods (including rankings and scientific reports) were discussed in this chapter). In chapter two, sources of information on academic publications, their origins and development (from bibliographic bases to citation indexes) were presented. A separate subchapter was devoted to databases of academic publications created by libraries of technical universities, and to indicators in the assessment of academic publications. Chapter three deals with electrotechnics as a field of science. An analysis was conducted with regard to the place of electrotechnics in science classifications based on selected examples, and the development of the teaching of electrotechnics at university level was shown. In this chapter, early and contemporary Polish journals on electrotechnics were presented, including journals published by technical universities themselves. Chapter four contains the results of an analysis of international databases (Scopus, WoS, CC), focusing on the representation of Polish journals, including their citations, and publications of authors with affiliation to Polish technical universities. Final conclusions of research and analyses have brought an answer to questions raised with regard to the assessment of representation in international databases of publications by Polish authors affiliated to Polish technical universities (in its various aspects, e.g., a publication type, language of publication, publication dynamics taking into account years of publications, cooperation with representatives of other European and non-European countries), and of Polish journals
