Towards a True Author Entry System for CAI
No full textCAI course authors have been faced with the disc tint problem of having to learn an instructional coding language before they can get their courses into the computer. A system has been devised so that an author may easily write his course in English on course planning forms and then a pre-processor will generate the coding which will be input for the machine assembler

Spectral Monte Carlo Simulation of Collimated Solar Irradiation Transfer in A Water-Filled Prismatic Louver
No full textA Monte Carlo model was developed to simulate collimated solar irradiation transfer and energy harvest in a hollow louver made of silica glass and filled with water. The full solar spectrum of air mass 1.5 database was adopted and divided into various discrete bands for spectral calculations. The band-averaged spectral properties for the silica glass and water were obtained. Ray tracing was employed to find the solar energy harvested by the louver. Computational efficiency and accuracy were examined through intensive comparisons of different band partition approaches, various photon numbers and element divisions. The influence of irradiation direction on solar energy harvest efficiency was scrutinized. It was found that within 15°polar angle of incidence the harvested solar energy in the louver was high, and the total absorption efficiency reached to 61.2% under normal incidence for the current louver geometry.Peer reviewe

Crown white with brown diamond-shaped spot at apex; pronotum white and semitransparent, anterior margin white, other parts indistinctly brown; scutellum pale yellow, basal triangles on scutum brown; face yellowish white, frontoclypeal area broad, anteclypeus somewhat pentagonal, lorum narrow; forewing sordid white without distinct dark markings preapically, margin of apical angle brown (Figs. 3, 8, 13, 18). Pygofer caudally broadly rounded, with 8–11 dorso-apical macrosetae, ventral appendage well developed (Fig. 62). Subgenital plate long, tapering apicad, with row of 3–4 macrosetae as single row, numerous fine setae sparsely distributed over surface laterad of macrosetae (Fig. 63). Style narrowing apicad (Fig. 67). Connective Y-shaped, arms short, 1 / 3 as long as stem (Fig. 66). Aedeagus broad and short, aedeagal shaft curved dorsad, with a pair of long, slender curved appendages arising from ventral part of expanded atrium and slightly surpassing shaft apex (Figs. 64–65).

Distribution. China (Sichuan, Shaanxi, Shanxi, Henan). Remarks. Among the species of Oniella this species is the palest, with the forewing lacking dark patches; this may be the reason Cai & Shen (1998) placed it in the genus Sophonia. However, this species has a long and narrow subgenital plate and the frontoclypeal area broad. These features are not present in the genus Sophonia. Therefore, this species is transferred to Oniella.Published as part of Min, Gao & Zhang, Yalin, 2013, Review of the leafhopper genus Oniella Matsumura (Hemiptera: Cicadellidae), with description of a new species from China in Zootaxa 3693 (1), DOI: 10.11646/zootaxa.3693.1.2, http://zenodo.org/record/21787

Penelitian pada siswa kelas V MIN Kawistolegi Karanggeneng Lamongan dilatarbelakangi oleh adanya kesulitan belajar siswa pada mata pelajaran IPA materi organ pernapasan manusia, sehingga diperlukan pengembangan media Computer Assisted Instruction (CAI) pada mata pelajaran IPA materi organ pernapasan manusia. Pengembangan ini bertujuan untuk menghasilkan sebuah produk media Computer Assisted Instruction (CAI) pada mata pelajaran IPA materi organ pernapasan manusia untuk siswa kelas V di MIN Kawistolegi Karanggeneng Lamongan yang layak dan efektif. Media Computer Assisted Instruction (CAI) dikemas dalam compact disk (CD) dan dilengkapi dengan bahan penyerta. Model pengembangan yang digunakan dalam pengembangan media Computer Assisted Instruction (CAI) adalah model pengembangan R&D (Research and Development) Borg and Gall dalam Sugiyono. Jenis data yang digunakan dalam pengembangan media ini yaitu data kualitatif dan kuantitatif yang didapat berdasarkan hasil wawancara kepada ahli materi dan ahli media, angket diberikan untuk uji coba perorangan, kelompok kecil, dan kelompok besar. Teknik analisis data yang digunakan adalah teknik persentase untuk wawancara dan angket, serta teknik uji-t untuk tes. Hasil uji kelayakan media Computer Assisted Instruction (CAI) berdasarkan hasil wawancara ahli materi 93,33% (baik sekali), ahli media 93,33% (baik sekali) serta hasil angket uji coba perorangan 84,44% (baik sekali), uji coba kelompok kecil 86,67% (baik sekali), dan uji coba kelompok besar 95,08% (baik sekali). Sehingga dapat disimpulkan bahwa media Computer Assisted Instruction (CAI) ini dikategorikan baik sekali dan layak digunakan dalam kegiatan pembelajaran IPA siswa kelas V MIN Kawistolegi karanggeneng Lamongan. Selanjutnya untuk keefektifan media Computer Assisted Instruction (CAI) diperoleh perhitungan dengan taraf signifikan 5% (Sugiyono,2010), d.b = N-1 = 28-1 = 27 (dikonsultasikan dengan table nilai t) dengan nilai t0,05 harga tabel = 2,052 maka dapat diketahui bahwa thitung lebih besar dari pada ttabel dengan perbandingan angka thitung = 15,23 > ttabel = 2,052. Sehingga dapat disimpulkan bahwa penggunaan media Computer Assisted Instruction (CAI) efektif dalam meningkatkan hasil belajar siswa pada mata pelajaran IPA materi organ pernapasan manusia kelas V di MIN Kawistolegi Karanggeneng Lamongan.

Abstract
The studies in class V MIN Kawistolegi Karanggeneng Lamongan motivated by the learning difficulties of students at science subjects of respiratory organs of human chapter, so development of media Computer Assisted Instruction (CAI) at science subjects of human respiratory organs chapter is needed. This development aims is to produce a media product of Computer Assisted Instruction (CAI) at science subjects respiratory organs of human chapter for class V MIN Kawistolegi Karanggeneng Lamongan students which are suitable and effective. Media Computer Assisted Instruction (CAI) is packaged in a compact disk (CD) and comes with accompanying materials.The model that used in the development of media Computer Assisted Instruction (CAI) was R&D (Research and Development) by Borg and Gall in Sugiyono. The type of data that used in the development of this media are qualitative and quantitative data which is obtained based on the results of interviews with subject experts and media experts, a questionnaire was given in individual test, small group test, and large group test. Data analysis technique used is the percentage of interview and questionnaires, and t-test techniques for the test.The results of media Computer Assisted Instruction (CAI) data analysts based on interview of subject experts 93.33% (excellent), media expert 93,33% (excellent) and the results of the questionnaire individual testing 84,44% (excellent), small groups test 86,67% (excellent), and large groups test95,08% (excellent). It can be concluded that the media Computer Assisted Instruction (CAI) is considered excellent and fit for use in science teaching activities in the fifth grader of MIN Kawistolegi Karanggeneng Lamongan. Furthermore, to the effectiveness of media Computer Assisted Instruction (CAI) obtained by calculations with significance level of 5% (Sugiyono, 2010), db = N-1 = 28-1 = 27 (in consultation with the table value of t) with a value t0,05 price table = 2,052 it can be seen that t-count is higher than t-table t = 15.23 > table = 2.052.

Incremento de prestaciones en el acceso en Grid de datos
No full textPonencias de las Decimosextas Jornadas de Paralelismo celebradas del 13 al 16 de septiembre de 2005 en GranadaEl modelo de computación Grid ha evolucionado
en los últimos años para proporcionar un entorno de computación de altas prestaciones en redes de área amplia. Sin embargo, uno de los mayores problemas se encuentra en las aplicaciones que hacen uso intensivo y masivo de datos. Como solución a los problemas de estas aplicaciones se ha utilizado la replicación. Sin embargo, la
replicación clásica adolece de ciertos problemas como la adaptabilidad y la alta latencia del nuevo entorno. Por ello se propone un nuevo algoritmo de replicación y organización de datos que proporciona un acceso de altas prestaciones en un Data Grid.Publicad
