Conoco Phillips Bayu-Undan II topsides tie-in project
No full textThis document is the final submission for the Engineering Internship unit (ENG450), undertaken at WorleyParsons Resources and Energy for a duration of 19 weeks. The main objective of the final year engineering internship is to provide exposure to the applied world of engineering design or research through a period of workplace employment in a relevant area of engineering. As such, it aims to address and develop several technical and process competencies as defined by Engineers Australia.
As a pre-cursor to the work undertaken as part of the Engineering Internship, the nature of the processes on the concerned facilities (Bayu-Undan) are explored. The scope of the specific Bayu-Undan II project assigned is subsequently defined in pursuit of increased hydrocarbon liquids and LNG production.
The work undertaken, as detailed in this report, encompasses the activities assigned to the Instrumentation and Control discipline in the preliminary 'planning' phase of the project (formally referred to as pre-Front End Engineering Design). These tasks/activities served as the primary deliverables required for this phase of the project.
An Instrument feasibility study is provided to essentially outline the scope of work required from an instrumentation perspective, in order to facilitate the defined 'flow-line' tie-ins to occur. As such, it provides the basis for specification and configuration of the associated instrumentation.
As a means of establishing a basis for the required modifications, the hardware components, layout, architecture and configuration of the control and shutdown systems on the existing facilities is subsequently explored. The modification and/or configuration of the control and shutdown systems, in order to accommodate the defined 'flow-line' tie-ins, are subsequently provided as the control and shutdown systems vendor scope of work. This also includes all required documentation defining the appropriate configuration and/or modification of these systems.
The tasks associated with the specification and procurement of several instrument packages have also been undertaken and are detailed within this report. Where possible, background research regarding instrument components, functionality and required specifications has been included
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
OP-5 Measuring Bowman's layer in the clinic
No full text*Correspondence, Stephen Kaye: [email protected] PURPOSE: To assess the accuracy, repeatability, and performance limits of in vivo Mirau ultrahigh axial resolution (UHR) line field spectral domain (LF-SD) optical coherence tomography (OCT) for the clinical in vivo measurement of Bowman's layer thickness in subjects with and without keratoconus. METHODS: Patients with keratoconus and volunteers with no corneal disease were included. The thickness of Bowman's layer was measured in the clinic. An in vivo graph search image segmentation of the central cornea was obtained at the normal interface vector orientation. The Mirau-UHR-LF-SD-OCT system used has an axial resolution down to 2.4 μm in air (1.7 μm in tissue), with an A-scan speed of 204.8 kHz and a signal to noise ratio (sensitivity) of 69 (83) dB. RESULTS: 40 patients with keratoconus and 20 healthy volunteers were included. The repeatability of mean Bowman's and epithelial thicknesses were 0.3 and 1.0 μm, respectively. The measured 95% population range for Bowman's layer thickness was 13.7 to 19.6 μm for healthy (mean 16.65, SD 1.48) and 10.94 to 16.99 for 23 of the keratoconics (mean 13.96 SD 1.51) (p<0.05). CONCLUSIONS: The measured thicknesses of Bowman's layer using the Mirau-UHR-LF-SD-OCT were both accurate, with the range for healthy in vivo thicknesses matching prior confocal and OCT systems of varying axial resolutions and repeatable. Bowman's layer was significantly thinner in patients with keratoconus. Bowman's layer can be accurately measured in the clinical setting using a Mirau-UHR-LF-SD-OCT and can be useful for disease monitoring
Imulasi Pengendalian Banjir pada Perkebunan Kelapa di Sungai Undan (Studi Kasus: Desa Sei Undan Kabupaten Indragiri Hilir)
No full textThe coconut plantation area on the banks of the Undan river is not function optimally. It can be seen from the inability of the river in flowing runoff discharge. The floods caused many dead coconut trees and disrupted the activities of residents in Sei Undan Village. Flood simulation analysis is done by analyzing the capacity of the river channel and comparing the calculated discharge it with rational method. Analyze channel calculation using HEC-RAS 4.1.0 software. Profile analysis is done by dividing into 2 river channels that reach A and B with 3 different reset times, is 5 years, 10 years, and 25 years. The result of this research can be seen that the existing condition with maximum height in reach B is 30 cm for return periode of 5 years, 30 cm for return periode of 10 years and 30 cm for return periode of 25 years and to reach A that is 19 cm for return periode of 5-years, 34 cm for return periode of 10 years, and 27 cm for return periode of 25 years. Simulation by constructing a levee on the riverbank by looking for Maximum inundation height with a higher levee size than the maximum inundation
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
BAYU/UNDAN GAS-CONDENSATE DISCOVERY: WESTERN TIMOR GAP ZONE OF COOPERATION, AREA A.
No full textThe Bayu/Undan Gas-Condensate Field straddles the boundary between the ZOCA 91-12 and ZOCA 91-13 PSC areas, within the Timor Gap Zone of Cooperation Area A (ZOCA). The field is located approximately 450 km northwest of Darwin, NT, and 350 km east-southeast of Kupang, Timor. The closure is the culmination of the Flamingo High, a major structural element within the northern Bonaparte Basin. This structure has been viewed as having significant hydrocarbon potential since Flamingo-1 recovered gas from Berriasian sandstones in 1971.The discovery well, Bayu-1, was drilled by the ZOCA 91-13 contract operator, Phillips Petroleum Company ZOC, in early 1995. Bayu-1 intersected a gross 155m gas-condensate column within Middle Jurassic sandstones at a depth of 2,954.5 mSS. The ZOCA 91-12 joint venture then drilled Undan-1,10 km northwest of Bayu-1, on a separate culmination within the closure defined by the Bayu-1 gas-water contact. Undan-1 and subsequent wells have confirmed the existence of one large gas-condensate field, with a most likely areal extent of over 160 km2.The sandstone reservoir consists of late Oxfordian to Callovian shallow marine, deltaic to shoreface, coarsening upward parasequences, overlying Callovian to Bajocian marginal marine to coastal plain sediments. The trap is an east-west oriented horst block bounded by en-echelon normal faults to the north and south, with dip closure to the east and west. Seal is provided by Tithonian to Barremian marine claystones. A likely hydrocarbon source is contained within the Barremian to Callovian interval, some of which are mature for condensate and wet gas expulsion in the southern Sahul Syncline and Malita Graben.</jats:p
PRELIMINARY STUDY OF NEPENTHES SPECIES IN BANJARAN UNDAN, SARAWAK, MALAYSIA
No full textNepenthes is a carnivorous plant with a current record of 160-180 species worldwide. The geographical distribution of Nepenthes is restricted to tropical areas, and most of them are found in the Malesian region. Its peculiar characteristics with different shapes and colours are portrayed by leaf modifications called pitchers. The pitchers are developed for living adaptation in poor soil conditions. Currently, in Sarawak, there are 33 taxa recorded and all are listed as Protected Plants under the Sarawak Wildlife Protection Ordinance 1998. Banjaran Undan is located near the community area and Pan Borneo Highway in Bau, Kuching Division with elevations 350–500 m above sea level. Surveys and studies of Nepenthes in Banjaran Undan were conducted along three different trails: Stenggang Dam trail, Sepadah Dam trail, and Foothill trail. The objective of this study is to provide baseline data of unique plants (including Nepenthes) as keystone genera for the conservation and protection of the Banjaran Undan. The distribution survey based on altitude was conducted every 100 m and the ecology of each Nepenthes species was described. All Nepenthes species in the surveyed areas were collected, identified and photographed for further analysis. Currently, there are six Nepenthes species were encountered at altitudes between 100–250 m which are N. ampullaria, N. gracilis, N.hirsuta, N. hispida, N. mirabilis, and N. rafflesiana. As the project is ongoing, and more areas are to be surveyed, potentially more taxa will be added to the list.
