Generating Natural Language from Linked Data:Unsupervised template extraction

We propose an architecture for generating natural language from Linked Data that automatically learns sentence templates and statistical document planning from parallel RDF datasets and text. We have built a proof-of-concept system (LOD-DEF) trained on un-annotated text from the Simple English Wikipedia and RDF triples from DBpedia, focusing exclusively on factual, non-temporal information. The goal of the system is to generate short descriptions, equivalent to Wikipedia stubs, of entities found in Linked Datasets. We have evaluated the LOD-DEF system against a simple generate-from-triples baseline and human-generated output. In evaluation by humans, LOD-DEF significantly outperforms the baseline on two of three measures: non-redundancy and structure and coherence.

Impact of Mining Activity upon Environment in Roşia Montană

Roşia Montană is the greatest gold ore in Romania and one of the greatest in Europe, and its exploitation has been carried out since Antiquity up to nowadays. If the traditional extraction and processing technologies had a minimal impact upon environment, the ones adopted in modern times have affected all the components of the natural environment. In the perspective of capitalizing the gold ore through the programme elaborated by the Canadian company, Gold Corporation, the zonal geographical space will be degraded up to the level of industrial dessert over an area of 100 km2 and in case of damage, the affected area can extend enormously. The environmental problems are related both to the specific nature of such an industrial activity and, especially, to the use of enormous quantities of sodium cyanide directly on the preparation flux from the industrial plant. Few such cases are known worldwide, in several economically less developed countries. Usually, cyanides are used for treating the gold concentrations, operation done in conditions of maximum security, in closed spaces, situated in isolated zones and the neutralization (detoxification) of cyanides is done in situ. The treatment of cyanides in open spaces has always generated environmental problems. Moreover, none of the cyanide treatment technologies eliminates entirely their toxic effect (less toxic chemical products are obtained). In order to avoid the production of an environmental disaster and to preserve the local patrimony values (in this place there lies the richest mining archeological site in Europe), we elaborated several recommendations we consider feasible as they allow both the capitalization of ore, which is a socio-economic necessity of the area, and the ecological reconstruction of the affected geographical space

HUBUNGAN STATUS GIZI DAN ASUPAN ENERGI TOTAL DENGAN PRESTASI BELAJAR ANAK USIA 9-17 TAHUN DI PANTI ASUHAN DI KOTA BANDA ACEH

ABSTRAK Fokus pengasuhan dan perhatian terhadap gizi anak-anak panti asuhan secara langsung kurang, serta perbandingan jumlah anak yang lebih besar dari pada jumlah ibu asuh menyebabkan perhatian terhadap status gizi lebih rendah. Penelitian ini bertujuan mengkaji hubungan antara status gizi dengan prestasi belajar anak usia 9-17 tahun di Panti Asuhan di Kota Banda Aceh. Jenis penelitian adalah analitik observasional dengan studi cross sectional dilakukan di Panti Asuhan Muhammadiyah, Panti Asuhan Yayasan BTRG, Panti Asuhan Penyantun Islam dan Panti Asuhan Nirmala Banda Aceh, tanggal 20 Oktober - 20 November 2017. Status gizi dengan pengukuran tinggi dan berat badan, serta pola konsumsi diukur dengan metode dietary history. Data dianalisis dengan Anthroplus WHO 2009 dan Nutrisurvey 2007. Nilai rata-rata asupan zat gizi yang didapat dibandingkan dengan Angka Kecukupan Gizi (AKG) Indonesia tahun 2013. Prestasi belajar adalah nilai laporan belajar (rapor). Hasil uji statistik antara status gizi dan prestasi belajar didapatkan nilai

Surface imaging of metallic material fractures using optical coherence tomography

We demonstrate the capability of optical coherence tomography (OCT) to perform topography of metallic surfaces after being subjected to ductile or brittle fracturing. Two steel samples, OL 37 and OL 52, and an antifriction Sn-Sb-Cu alloy were analyzed. Using an in-house-built swept source OCT system, height profiles were generated for the surfaces of the two samples. Based on such profiles, it can be concluded that the first two samples were subjected to ductile fracture, while the third one was subjected to brittle fracture. The OCT potential for assessing the surface state of materials after fracture was evaluated by comparing OCT images with images generated using an established method for such investigations, scanning electron microscopy (SEM). Analysis of cause of fracture is essential in response to damage of machinery parts during various accidents. Currently the analysis is performed using SEM, on samples removed from the metallic parts, while OCT would allow in situ imaging using mobile units. To the best of our knowledge, this is the first time that the OCT capability to replace SEM has been demonstrated. SEM is a more costly and time-consuming method to use in the investigation of surfaces of microstructures of metallic materials. © 2014 Optical Society of America

Manajemen Pencegahan Kejahatan Bagi Pegawai Bp Indonesia: Kebijakan Departemen Sekuriti Bp Indonesia untuk Mencegah Pegawai Bp Indonesia Menjadi Korban Potensial

This bachelor thesis tries to explain policies which have been using by BP Indonesia's Security Department as part of multinational oil company to prevent BP Indonesia's Employees from being victimized. Preventing BP Indonesia's Employees from being victimized enable them to show their best and BP Indonesia can regain benefit. Researcher used qualitative method in order to get an in depth and precise data. In order to get an in depth and current analyzes, participant observation, secondary data search, interviews and assessments had been used by researcher. In depth and collaborative analyzed had been used by researcher according to criminological theories such as security management theory, situational crime prevention and social crime prevention theory. Findings suggest that BP Indonesia Security Department have done their job so well that they don't have to increase their security breach in order to prevent the worst. According to experiences and recommendations from BP Indonesia's employees, technical methods needs to be upgraded for the sake of employees comfort
