Abstract
An increasing number of field development projects include rigorous uncertainty quantification workflows based on parameterized subsurface uncertainties. Model calibration workflows for reservoir simulation models including historical production data, also called history matching, deliver non-unique solutions and remain technically challenging. The objective of this work is to present a manageable workflow design with well-defined project workflow tasks for reproducible result presentation. Data analysis techniques are applied to explore the information content of multiple-realization workflow designs for decision support.
Experimental design, sampling and Markov Chain Monte Carlo (MCMC) techniques are applied for case generation. Data analytics is applied to identify patterns in data sets supporting the evaluation of the history matching process. Visualization techniques are used to present dependencies between contributions to the history matching error metric. Conflicting history matching responses are identified and add value to the interpretation of history matching results. Probability maps are calculated on the basis of multiple-realizations sampled from a posterior distribution to investigate potentially under-developed reservoir regions.
Technologies are applied to a real gas field in the Southern North Sea. For the purpose of the benchmark, a structured workflow design to history matching and estimation of prediction uncertainty is presented. Sensitivity evaluations are used to identify key uncertain input parameters and perform parameter reduction. Markov Chain Monte Carlo (MCMC) is applied for optimization and uncertainty quantification. Statistical stability of key performance parameters is verified by repeating relevant phases of the workflow several times. In conclusion practical consequences and best practices as well as the use of data analytics in history matching workflows are discussed.

Published: March 2017

Buton Sultanate is a prosperous maritime sultanate in its heyday. Buton Sultanate land is not very fertile and does not produce a lot of commodities, but it is quite well known because of its location in the commercial lines, so that it becomes a stopover place for passing ships. This paper provides an overview of ecological archaeology towards the triumph case of Buton Sultanate in the 17th-18th century. The research method used in this paper is literature study and review of a theory through an observation of cultural ecology and environmental determinism. The results show that the ecological aspects affect the heyday of the Buton Sultanate. Buton Sultanate does not produce a lot of major commodities, but it is successfully adapt to environmental conditions and maximize the benefits derived from the ecological aspects by applying it to the structure of Sultanate society, a commercial network, and material culture. The profits are also applied to maintain its legitimacy in the great power of hegemony in the region. Success in 'conquering' the environment makes the Buton Sultanate victorious, even the identity of 'kebutonan' still embedded in Buton society until this day.Kesultanan Buton merupakan kesultanan bercorak maritim yang cukup besar pada masa jayanya. Daratan Kesultanan Buton tidak begitu subur dan tidak banyak menghasilkan komoditi namun cukup terkenal karena lokasinya terletak di jalur niaga, sehingga menjadi lokasi singgah bagi kapal-kapal yang melintas. Penelitian ini berisi tinjauan arkeologi ekologi terhadap kasus kejayaan kesultanan Buton abad ke-17-18. Metode penelitian menggunakan studi pustaka dan tinjauan teori melalui tinjauan model cultural ecology dan environmental determinism. Hasil penelitian menunjukkan bahwa aspek-aspek ekologi berpengaruh terhadap kejayaan Kesultanan Buton. Kesultanan Buton tidak banyak menghasilkan komoditi utama, namun berhasil menyesuaikan diri dengan kondisi lingkungannya dan sukses memaksimalkan keuntungan-keuntungan yang diperoleh dari aspek ekologis. Dengan menerapkannya pada struktur masyarakat Kesultanan, jaringan perniagaan, budaya material, Kesultanan Buton mempertahankan legitimasi dalam hegemoni kekuatan besar di wilayahnya. Kesuksesan dalam ‘menaklukan’ lingkungan menjadikan Kesultanan Buton berjaya, bahkan hingga saat ini identitas ‘kebutonan’ masih melekat di dalam masyarakat Buton.

AbstrakKepulauan Maluku telah dikenal dalam jaringan perdagangan di Nusantara sejak masa lampau. Wilayah ini masuk dalam jaringan perdagangan karena merupakan sumber utama komoditi rempah-rempah khususnya cengkih dan pala. Berbagai catatan historis yang ada telah memberikan konfirmasi bahwa komoditi yang dihasilkan dari wilayah ini telah diperdagangkan hingga ke Eropa dan tempat-tempat lain di dunia. Tulisan ini membahas tentang jalur perdagangan dan pelayaran dalam konteks perdagangan rempah-rempah, bandar-bandar niaga di perairan Maluku, serta kehancuran peran perdagangan rempahrempah di Maluku. AbstractMaluku Islands are known in the trade network in the archipelago since past. These areas included in the network as the main source of commodity trading of spices, especially cloves and nutmeg. Existing historical records has confirmed that the commodities produced from this region have been trafficked to Europe and other places in the world. This paper discusses the trade and shipping in the context of the spice trade, the commercial port in the waters of the Moluccas, and the destruction of the role of the spice trade in the Moluccas.
Probabilidade de ruína de estacas helicoidais nas fundações de torres de linhas de transmissão
Authors: Marques das Neves Alessandro , Reis Jeselay 
Published: March 2017

Nos projetos de linhas de transmissão são inúmeras as variabilidades devido ao fato da linha de transmissão consistir em uma obra que pode se estender por vários quilômetros, passando por diversas unidades geológicas e diferentes microclimas. As mudanças de unidade geológicas causam variabilidade na resistência e as mudanças de microclimas inserem variabilidades nas solicitações. Desta forma, neste trabalho faz-se uma avaliação da probabilidade de ruína e da segurança de um trecho da Linha de Transmissão de alta tensão 230 kV executada em sua maioria com torres do tipo estaiadas e fundações em estacas helicoidais. O cálculo das solicitações das torres foi feito pelo software Tower considerando os mapas de vento da região. As resistências foram determinadas com base no torque de instalação das estacas, calibrados a partir de ensaios de arrancamento. Obteve-se como resultados a probabilidade de ruína e os coeficientes de segurança que permitiram concluir que quando as estacas helicoidais são executadas tendo como referência na instalação o torque de projeto a probabilidade de ruína é praticamente nula; porém, quando se toma como referência durante a instalação a profundidade mínima prevista em projeto, a probabilidade de ruína da Linha de Transmissão aumenta consideravelmente.

Simulation of protected and unprotected loss of flow transients in a WWER-1000 reactor based on the Drift-Flux Model
Authors: Baghban G. , Shayesteh M. , Bahonar M. 
Published: March 2017

Abstract
In view of the importance of studying coolant transient behavior in a nuclear reactor, this work is devoted to the thermal-hydraulic analysis of protected and unprotected loss of flow transients in a WWER-1000 reactor. A series of corresponding mathematical and physical models based on the four-equation Drift-Flux model has been applied. Based on a multi-channel approach, the core has been divided into different regions. Each region has different characteristics as represented in a single fuel pin with its associated coolant channel. Appropriate initial and boundary conditions have been considered and two situations of tripping four and two primary pumps in a protected core in addition to situation of tripping all four pumps in an unprotected core have been analyzed. For each transient, a full range of thermal-hydraulic parameters has been obtained. For verification of the proposed model, the results have been compared with those of the RELAP5/MOD3 and Bushehr nuclear power plant Final Safety Analysis Report (FSAR). A good agreement between results has been attained for the aforementioned transients.
Evolution of the temperature, microstructures and microsegregation in equiaxed solidification of Al-5 wt.% Cu alloy
Authors: Ma Xiaoping , Li Dianzhong 
Published: March 2017

AbstractIn this study, the evolutions of the microstructures and microsegregation are related to the cooling curve in equiaxed dendritic solidification of the Al-5 wt.% Cu alloy. In addition to regular branching of dendritic arms, leaf venation branching, free branching and radial branching were also observed. With the extension of the dendritic zone, both the composition of the extra-dendritic melt and average composition of the dendritic zone change. The microsegregation mechanism in the dendritic zone deviates from the modified Scheil model. The microsegregation data suggest that the single dendritic arm is a porous structure containing the trapped boundary layer. As the temperature decreased after the isothermal periods, some original dendritic arms and interdendritic melt converged to form a new dendritic arm.

Le karst post-pliocène de la région de Safi (Maroc atlantique)
Authors: Weisrock André , Lunski Simon 
Published: March 2017

Sur 20 km de largeur en moyenne, l'arrière-pays de Safi correspond à la rasa plio-moghrébienne qui recouvre un substratum mésozoïque à niveaux gypseux. calcaires et marneux assez peu déformé.
Le karst superficiel se développe dans les lumachelles et les calcarénites biodétritiques du Plio-Moghrébien et leurs recouvrements continentaux limono-calcaires, peu épais. Il s'agit de petites dolines («daïa») isolées ou réunies en ouvalas et poljés peu profonds, plus rarement de puits reliés à un réseau souterrain. Les principales directions des alignements sont N170-N195, N040-N070 et N080-N115.
Deux problèmes principaux se posent au sujet de la genèse de ce karst post-pliocène :
- celui de ses relations avec un karst plus ancien qui affecte les assises mésozoïques et en particulier les horizons gypseux. Ce dernier peut guider le réseau karstique superficiel, mais il peut à l'inverse être «rajeuni» par le rejeu tectonique syn- et post-pliocène ;
- celui de la dissolution qui n'a pu s'effectuer que dans les périodes de climat plus humide que l'actuel (318 mm/an). Les datations effectuées dans les fonds de cuvettes karstiques montrent que celles-ci se sont encore creusées au Pléistocène supérieur.
Deux siècles d'étude des libellules en Rhône-Alpes (Insecta : Odonata)

Published: March 2017

Two centuries of regional odonatology
A general presentation of the order Odonata (systematics, biology) is proposed first of all, followed by information on these insects in Rhone-Alpes, a region situated at the crossroads of Alpine, Atlantic and Mediterranean climates. Then, a synthesis summarizes more than two centuries of regional odonatology, where the local status of 7 species is discussed and specified. Finally, the study leads to the report of an improvement of the biodiversity of the regional dragonflies, especially owed these last 50 years to a much better knowledge of their current distribution and, additionally, to the effects of the global warming.
