Published: September 2015

Abstract
Fine particles aggregating into larger units or flocculation body is a random combination process. Increasing the size and density of flocculation body is the main approach to rapid particle removal or sedimentation in water. Aiming at the Brownian coagulation of fine particles, a new method of Taylor expansion moment construction of fractal flocs has been developed in this paper, incorporating the Taylor expansion approach based on the moment method and the fractal dimension of the floc structure originated from fractal theories. This method successfully overcomes the limit of previous moment methods that require pre-assumed particle size distribution. Results of the zero and second order moments of Brownian flocs from the proposed method are compared with those from the Laguerre method, integral moment method and finite element method. It is found that the higher accuracy and efficiency of computation have been achieved by the new method, compared to the previous ones. Effects of the fractal dimension on the zero and second order moments, geometric average volume and standard deviation are also analyzed using this method. The self-conservation characteristics of particle distribution is observed without presumption of initial distributions.
Numerical Solution of Nonlinear Kaup-Kupershmit Equation, KdV-KdV and Hirota-Satsuma Systems
Authors: Mohebbi Akbar 
Published: September 2015

Abstract
In this work we investigate the numerical solution of Kaup-Kupershmit (KK) equation, KdV-KdV and generalized Hirota-Satsuma (HS) systems. The proposed numerical schemes in this paper are based on fourth-order time-stepping schemes in combination with discrete Fourier transform. We discretize the original partial differential equations (PDEs) with discrete Fourier transform in space and obtain a system of ordinary differential equations (ODEs) in Fourier space which will be solved with fourth order time-stepping methods. After transforming the equations to a system of ODEs, the linear operator in KK and HS equation is diagonal but in KDV-KDV equation is not diagonal. However for KDV-KDV system which is the focus of this paper, we show that the exponential of linear operator and related inverse matrix have definite structure which enable us to implement the methods such as diagonal case. Comparing numerical solutions with exact traveling wave solutions demonstrates that those methods are accurate and readily implemented.

<p>This study is about syariah banking. The secondary data, obtained from the published reports of Bank Indonesia (BI) was used. It consists of Islamic Banking Statistics (SPS) and the Progress Report on Islamic Banking (LPPS). The analytical methods used were multiple linear regression, F test and t test. Based on the calculation of F test, deposit indicators - ROA, NPF, FDR, and the ratio jointly influence the market share of Islamic banking in Indonesia. Further, based on t test that had been done, the variable deposits, ROA, NPF and the ratio have a significant effect, while the FDR variables have no significant effect to the market share of Islamic banking in Indonesia. Then, DPK variables, ROA, and FDR have a positive effect while the NPF and the ratio have a negative effect on the market share of Islamic banking in Indonesia. From the analysis, it can be implied that the bank should increase deposits and ROA because they will have an effect on increasing the market share of Islamic banking in Indonesia; and the NPF and the bank should lower the ratio because they will reduce the market share of Islamic banking in Indonesia.</p><p> </p><p align="center"> </p><p>Penelitian ini mengenai perbankan syariah.

Vergleich rektaler und sonographischer Untersuchungsbefunde bei der Kolik des Pferdes
Authors: Bankert J. , Brehm W. , Scharner D. 
Published: September 2015

ZusammenfassungGegenstand und Ziel: Neben der routinemäßigen Untersuchung des Kolikpatienten (klinische inklusive rektale Untersuchung), kommt zunehmend die Sonographie zur Anwendung. Ziel der Studie war, die Befunde der rektalen Untersuchung mit denen der sonographischen Untersuchung bei unterschiedlichen Kolikerkrankungen zu vergleichen. Material und Methoden: In einer retrospektiven Studie wurden die Patientendaten von Pferden mit Koliksymptomen der Jahre 2012 und 2013 der Chirurgischen Tierklinik Leipzig ausgewertet. Die anhand der rektalen und sonographischen Untersuchung gestellten Verdachtsdiagnosen wurden gruppiert und den Diagnosen (Goldstandard) der operativen Behandlung bzw. der pathologischen Untersuchung gegenübergestellt. Bei konservativ behandelten Tieren wurde nur bei eindeutigem rektalem Befund eine definitive Diagnose formuliert. Für beide diagnostische Verfahren erfolgte die Ermittlung von Sensitivität, Spezifität, positivem und negativem Vorhersagewert. Ergebnisse: Bezüglich der Diagnostik des Dünndarmverschlusses erwies sich die sonographische Untersuchung als deutlich sensitiver als die rektale Befunderhebung (97,1%; 50,7%). Eine bessere Sensitivität erzielte die sonographische Untersuchung auch bei der Längsachsendrehung des großen Kolons (63,2% vs. 26,3%) und bei der Verlagerung des großen Kolons in den Milz-Nieren-Raum (90,9% vs. 72,7%). Im Fall von Kolonverlagerungen bzw. Verstopfungen des großen Kolons war die rektale Untersuchung weitaus sensitiver als die sonographische Untersuchung (96,5% vs. 8,8%) bzw. (93,6% vs. 29,8%). Schlussfolgerung und klinische Relevanz: Besonders schwerwiegende Erkrankungen, wie der Dünndarmverschluss und die Längsachsendrehung des großen Kolons, werden mithilfe der Sonographie sicherer erkannt als durch die rektale Untersuchung. Deshalb sollte unter Klinikbedingungen auf die sonographische Untersuchung des Kolikpatienten nicht verzichtet werden. Bei der Diagnostik von Verlagerungen und Verstopfungen des großen Kolons sowie von Blinddarmerkrankungen erweist sich hingegen die transrektale Palpation gegenüber der Ultraschalluntersuchung überlegen.
The effects of Professional and Pedagogical Program Development Environments on Novice Programmer Perceptions
Authors: Vogts D , Calitz A P , Greyling J H 
Published: September 2015

Novice programmers generally have difficulty learning to program and one of the problems contributing towards this is the program development environment used at tertiary institutions. A number of pedagogical program development environments have been developed specifically for novice programmers, but these have not been compared experimentally with professional program development environments. A study was conducted that compared the perceptions of novice programmers using a representative
professional program development environment to a pedagogical program development environment during an Introductory Programming module at a tertiary institution. It was found that the use of a pedagogical program development environment had a positive effect on the feelings of achievement and learning while learning to program, while the perceived ease of using the program development environment and the perceived difficulty of practical assignments were not affected.

Published: September 2015

The collocation of software development teams is common, specially in agile software development environments. However little is known about the impact of collocation on the team’s effectiveness. This paper explores the impact of collocating agile software development teams on a number of team effectiveness factors. The study focused on South African software development teams and gathered data through the use of questionnaires and interviews.
The key finding was that collocation has a positive impact on a number of team effectiveness factors which can be categorised under team composition, team support, team management and structure and team communication. Some of the negative impact collocation had on team effectiveness relate to the fact that team members perceived that less emphasis was placed on roles, that morale of the group was influenced by individuals, and that collocation was invasive, reduced level of privacy and increased frequency of interruptions. Overall through it is proposed that companies should consider collocating their agile software development teams, as collocation might leverage overall team effectiveness.

Authors: Balli Umut , Aydogdu Ahmet , Dede Figen Ongoz , Turer Cigdem Coskun , Guven Berrak 
Published: September 2015

Background: To investigate changes in the levels and relative ratios of sclerostin, osteoprotegerin (OPG), and receptor activator of nuclear factor‐κB ligand (RANKL) in the gingival crevicular fluid (GCF) of patients with periodontitis after non‐surgical periodontal treatment.Methods: Fifty‐four individuals (27 healthy controls and 27 patients with chronic periodontitis [CP]) were enrolled in the study. Periodontitis patients received non‐surgical periodontal therapy. GCF sampling and clinical periodontal parameters were assessed before and 6 weeks after therapy. Sclerostin, OPG, and RANKL levels were measured by enzyme‐linked immunosorbent assay, and their relative ratios were calculated.Results: Total amounts and concentrations of sclerostin were significantly higher in patients with CP than in healthy individuals (P <0.025) and decreased after treatment (P <0.05). The RANKL/OPG ratio was significantly lower in healthy individuals than in patients with periodontitis before and after treatment (P <0.025), but no significant difference was observed in patients with periodontitis after treatment (P >0.05). The sclerostin/OPG and sclerostin/RANKL ratios were significantly lower in healthy individuals than in patients with periodontitis before and after treatment (P <0.025) and decreased in patients with periodontitis after treatment (P <0.05).Conclusions: The GCF sclerostin level may be more reliable than the RANKL/OPG ratio as a diagnostic and prognostic marker of periodontal disease and treatment outcome. Regulation of sclerostin levels may aid the development of new therapeutic strategies for the treatment of periodontal disease.

Abstract
ADCO's onshore oil field lies along an elongated highly faulted northeast-southwest anticlinal trend. The main reservoirs are part of the Lower Cretaceous Upper Thamama Group, in particular the Shuaiba and Kharaib Formations interbedded with dense limestones. The impact of faults and associated fractures on fluid flow and reservoir connectivity within the field has been previously uncertain. Flow in these reservoirs is believed to be matrix dominated, but there is some evidence that fracturing enhances fluid flow in some areas as well as vertically across dense zones. This might become more pronounced with changes in reservoir pressure. This paper describes an integrated approach in detecting occurrence and disposition of fractures, their impact on fluid flow and sensitivity to changes of in-situ stresses.
ADCO has interpreted many faults from 3D seismic data, and has drilled a deviated cored well across a major fault in the reservoir. Core, logs, image log, petrographic analysis and pressure measurements across the fault have provided invaluable information and knowledge in understanding the relationships between fracture occurrence and rock mechanical/petrophysical properties. This is complemented with fracture characterization and structural interpretation from image logs of 32 vertical, deviated and horizontal wells. Finer scale structural information has been extracted from inspection of the cores from more than 30 wells.
Overall, fractures are scarce, but their occurrence has given encouraging correlation with (1) reservoir rock type, (2) porosity, (3) distance to fault and (4) structural anomalies evident in seismic curvature attributes. These correlations support the extrapolation of interpretations away from the wells to identify where fractures are most likely to affect reservoir performance. Quantification of the effect of such fractures on production have been calibrated using an integrated analysis of lab test scale permeability at different confining pressures alongside CT-scans identifying small scale fracturing, and in-situ permeability measurements from well tests and production logging of well intervals with imaged fractures.
The novel parts of the workflow are how this characterization has produced a 3D discrete fracture network model with apertures of fractures controlled by present or future in-situ stress. When this fracture model is integrated with the 3D geomechanical model, the upscaled directional fracture permeabilities have shown sensitivity to production behavior based on the degree of reservoir depletion / injection.
Generation of Black-Oil PVT Properties Tables Using Tuned EOS Model by Integrating PVT Laboratory Test Datasets
Authors: Singh Ajay , Khan Hasnain 
Published: September 2015

Abstract
This paper describes the workflow used to develop a systematic approach for integrating a large number of pressure-volume-temperature (PVT) datasets and generating representative PVT tables for use in a black-oil reservoir simulation. The field in this study is a faulted carbonate reservoir with multiple producing zones. A variation in PVT properties was evident from laboratory tests conducted on the collected fluid samples. The challenge was to design a systematic approach for capturing PVT property variations, performing oil compositional variation modeling, and understanding PVT compartmentalization. A simplified approach is proposed that combines PVT properties variation and PVT compartmentalization into a single workflow. PVT properties variations were used to identify various trend lines, and PVT samples belonging to a trend line were assigned to one PVT compartment. An equation of state (EOS) model was tuned for each PVT compartment, and the tuned EOS was used to model compositional variation and properties variation with depth. Validation of the workflow was performed by assessing the quality of the EOS tuning and EOS calculated compositional gradient match with laboratory measured data. It was discovered that EOS models were able to capture PVT properties variation and compositional variation with depth. The workflow was found very useful for generating a new set of PVT tables required for history matching reservoir pressure.

Abstract
This paper presents our work on developing parallel reservoir simulators for improving oil recovery on distributed-memory parallel systems and studying the scalability of our parallel reservoir simulators. The reservoir simulators are based on our in-house parallel platform, PRSI (Parallel Reservoir Simulation Infrastructure), which provides grid, data, linear solvers, preconditioners, distributed matrix and vector management, well modeling and visualization support. Based on this platform, a black oil simulator and a thermal simulator have been implemented. Benchmarks show that our parallel simulators are thousands of times faster than sequential simulators that designed for workstations and personal computers.
