Deadwood in logged-over Dipterocarp forests of Borneo

Deadwood is an important stock of carbon in logged-over Dipterocarp forests but still remains poorly studied. Here we present the study of deadwood in logged-over Dipterocarp forests using two common approaches: plot-based approach and line-intersect-based approach. We conducted our research in three sites which are forest logged in 2003, 2007, and 2010 within Hutansanggam Labanan Lestari (HLL) forest, a certified forest concessionaire in Indonesia. We established 1,500 m of transect line (broken down in 50 m section) for each site. As a reference, we established 47 10 m x 10 m subplot for three sites. All fallen deadwood with diameter > 10 cm were recorded. Our results shows that the mass of fallen deadwood resulted by line-intersect-based method was much higher in compare to plotbased method. The mass of fallen deadwood in plot-based study (44.563 ± 9.155 Mg/ha) was significantly different with the mass of fallen deadwood in line-intersect-based study (69.587 ± 8.079 Mg/ha). Furthermore, for the variability of deadwood, both methods show consistence results which is the variability in 2003 was lower than that in 2007 and 2010. Based on our data, in order to get coefficient of variation of 10%, we recommend the use of minimum 40 plots of 20 m x 20 m to estimate deadwood in logged-over Dipterocarp forests. (Texte intégral

Automated screening of propulsion system test data by neural networks, phase 1

The evaluation of propulsion system test and flight performance data involves reviewing an extremely large volume of sensor data generated by each test. An automated system that screens large volumes of data and identifies propulsion system parameters which appear unusual or anomalous will increase the productivity of data analysis. Data analysts may then focus on a smaller subset of anomalous data for further evaluation of propulsion system tests. Such an automated data screening system would give NASA the benefit of a reduction in the manpower and time required to complete a propulsion system data evaluation. A phase 1 effort to develop a prototype data screening system is reported. Neural networks will detect anomalies based on nominal propulsion system data only. It appears that a reasonable goal for an operational system would be to screen out 95 pct. of the nominal data, leaving less than 5 pct. needing further analysis by human experts

Narrativa emergente contra a indústria extractiva em Tete : renegociando instituições através de protestos populares?

O presente artigo discute a interacção de cinco variáveis fundamentais, nomeadamente protestos populares, responsabilidade social empresarial (RSE), arranjos institucionais, desenvolvimento local e inclusão social. Esta análise foi desenvolvida com recurso ao Structural Equation Modeling (SEM), concretamente na modalidade da Análise Factorial Confirmatória (AFC). Os resultados mostram forte relação de causalidade entre protestos populares e arranjos institucionais. Contudo, os reajustamentos dos dispositivos legais do sector mineiro não se têm traduzido na melhoria das condições de vida das famílias afectadas pela actividade mineira em Tete.O presente artigo resulta de uma pesquisa financiada pela Fundação Calouste Gulbenkian com o apoio da FCTinfo:eu-repo/semantics/publishedVersio

ABSTRACT An error analysis of result from narrative essay of students was selected in this research based on the fact that the skill of writing was one of the language skills that was not easy. It was evidenced by the presence of some errors made by students of the Department of French Language Education on the results of their narrative essay, both morphological errors, syntax errors, vocabulary errors, spelling and punctuation errors. This study aims to determine, analyze and describe the ability of students in writing a French essay; the kinds of errors made by students on narrative essay test based the DELF A2; the factors that cause students difficulty in writing a narrative essay in French. The method used in this research is descriptive analytic. The analysis showed that the level of students ability to write a narrative essay based on the results of the test DELF A2 are satisfactory . The test results showed that there were 503 errors made by 42 students, with the kind of error that most taxonomy of linguistic especially lexicon errors. While the results of the questionnaire showed 48 % of students said that the causes of their difficulties in writing a narrative essay is limited French vocabulary and less practice of writing essays in French. Key words: Classification of errors, narrative essay, DELF A2. Analisis kesalahan hasil karangan narasi mahasiswa berdasarkan hasil tes berbasis DELF A2 dipilih untuk diteliti didasarkan pada sebuah fakta bahwa keterampilan menulis merupakan salah satu keterampilan berbahasa yang tidak mudah. Hal tersebut dibuktikan dengan terdapatnya beberapa kesalahan yang dilakukan mahasiswa Jurusan Pendidikan Bahasa Perancis pada hasil karangan narasi mereka, baik kesalahan morfologis, kesalahan sintaksis, kesalahan kosakata, kesalahan ejaan dan tanda baca. Penelitian ini bertujuan untuk mengetahui, menganalisis dan mendeskripsikan kemampuan mahasiswa dalam menulis karangan berbahasa Perancis; jenis-jenis kesalahan yang dilakukan mahasiswa pada karangan narasi yang dibuat berdasarkan soal tes DELF A2; faktor-faktor yang menyebabkan mahasiswa kesulitan dalam menulis karangan narasi berbahasa Perancis. Metode penelitian yang digunakan dalam penelitian ini adalah metode deskriptif analitik. Hasil analisis menunjukkan bahwa tingkat kemampuan mahasiswa dalam menulis karangan narasi berdasarkan hasil tes berbasis DELF A2 berada pada tingkat memuaskan. Hasil tes menunjukkan terdapat 503 kesalahan yang dilakukan oleh 42 orang mahasiswa, dengan jenis kesalahan terbanyak yaitu taksonomi kategori linguistik khususnya kesalahan leksikon. Sedangkan hasil angket menunjukkan 48% mahasiswa mengatakan bahwa faktor penyebab mereka kesulitan dalam menulis karangan narasi berbahasa Perancis adalah kosakata yang terbatas dan kurangnya berlatih menulis karangan narasi dalam bahasa Perancis.
