No full textRisk based inspection of flood defence dams: An application to grass revetments
No full textIn The Netherlands, inspection and maintenance are essential for maintaining stringent flood protection standards. Flood defences are assessed every 12 years to ensure they meet their risk-based safety standards,which are given as legally-binding maximum failure probabilities. Between assessments, flood defence managers are subject to risk-maintenance requirements: they must ensure that the failure probability of the defence does not increase in excess of its safety standard. However, there is no prescribed methodology to meet this requirement. In the study presented here, we developed a method which enables flood defence managers to derive inspection strategies using visual inspection data that will allow them to meet their risk-maintenance requirements.We applied the method to the assessment of grass revetments on the outer slope of the Oesterdam, one of the dams of the Dutch Delta Works. The application illustrates how – using visual inspection data, degradation information, and a failure mechanism model – inspection intervals can be derived that will ensure the risk-maintenance requirements are met.Accepted Author ManuscriptHydraulic Structures and Flood Ris

M.H., Diah Pawestri Maharani, S.H., M.H Fakultas Hukum Universitas Brawijaya Email: [email protected] ABSTRAK Artikel ini menganalisis mengenai kegiatan konversi cryptocurrency (bitcoin) ke dalam mata uang rupiah ditinjau dari Pеraturan Bank Indonеsia Nomor 18/40/Pbi/2016 Tеntang Pеnyеlеnggaraan Pеmrosеsan Transaksi Pеmbayaran. Analisis ini dilatarbelakangi oleh kegiatan transaksi konversi cryptocurrency ke dalam mata uang rupiah yang sedang terjadi di Indonesia hal ini menjadi masalah karena kegiatan tersebut tidak ada peraturan yang jelas dan mengingat penggunaan cryptocurrency telah dilarang sebagai alat pembayaran di Indonesia, karena tidak ada negara yang memback up bitcoin sebagai mata uang. Analisis ini menggunakan metode penelitian pendekatan undang-undang dan di interpretasi dengan menggunakan metode gramatikal dan teologis. Berdasarkan hal tersbut maka dapat disimpulkan tidak adanya peraturan yang membahas secara spesifik mengenai konversi cryptocurrency (bitcoin) akan tetapi ada pemberitahuan dari pemerintah untuk hati-hati terhadap kegiatan ini dan adanya alasan cryptocurrency (bitcoin) dilarang sebagai alat pembayaran membuat penulis merekomendasikan bahwa kegiatan konversi cryptocurrency (bitcoin) ini dapat membahayakan masyarakat karena merupakan economic bubble dan melarang perusahaan yang memfasilitasi jual beli cryptocurrency untuk melanjutkan kegiatannya. Kata Kunci: Konversi, Cryptocurrency, Mata Uang ABSTRACT This article analyses conversion of cryptocurrency (bitcoin) into rupiah from the perspective of Bank Indonesia Regulation Number 18/40/Pbi/2016 concerning Payment Process. This analysis was initiated based on the issue over cryptocurrency conversion into rupiah while there is no clear regulation on the use of cryptocurrency and this conversion has been regarded invalid as a payment method in Indonesia because there are no countries backing up bitcoin as a currency. This analysis employed statute approach interpreted by grammatical and theological methods. The result concludes that there is no regulation specifically regulating the conversion of cryptocurrency (bitcoin) but there is still a notification from the government for people to be more careful for this activity and reasons are given over why cryptocurrency is banned as a transaction in payment. This issue leads to the recommendation made by the author that this activity could harm societies recalling that this is regarded as economic bubble and it is recommended that companies stop facilitating cryptocurrency transaction to execute any activities in the companies.

Lessons learned from data analytics, applied to the track maintenance of the dutch high speed line
No full textLife cycle performance and risk management are often mentioned as critical tasks for infrastructure managers. However, without proper data collection and analytics these tasks cannot be executed. This paper discusses lessons learned from a case where a data analytics approach was deployed when an unexpected phenomenon occurred on the Dutch High Speed Line (HSL-Zuid). In November 2014, it was found that large sections of the HSL-Zuid were affected by a severe type of rolling contact fatigue (RCF). The RCF resulted in deep cracks on top of the rail. These damages were unexpected as the rails were only 5 years in operation and these rails were expected to last about 20–25 years with proper maintenance. In this case, resulting in about 20 km of rail replacements and multiple additional grinding campaigns. As the causes of defects were unknown, the authors applied data analytics to evaluate the possible causes of the RCF. Several measurements of the infrastructure, maintenance and the rolling stock resulted in a set of parameters. Then, a bottom-up approach is proposed for evaluating the affected sections to find similar parameter values among these over the whole track. The idea was to look for parameter values which could explain why certain sections were affected by the defects while others were not. The outcomes of the analysis indicated that it is highly likely that one type of rolling stock was affecting the rails in the curves of the HSL-Zuid. As the track was designed at the high-speed sections for 220–300 km/h and this type of rolling stock was driving below design speed, different loading of the rails throughout the curves occurred. Lessons learned from this case do not only apply to the technical area of wheel/rail and vehicle/infrastructure interfacing, but also to the usage of data analytics itself and life cycle management. From this case study, it is discussed how data collection and analytics can be better embedded by (rail) infrastructure managers from an early stage of development and use of infrastructure. Further scientific development for infrastructure data analytics are also discussed.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Integral Design & ManagementRailway Engineerin

The tittle of this final report is “Analysis of Sources and Uses of Working Capital at PD. Pasar Palembang Jaya”. PD. Pasar Palembang Jaya is the result of the reorganization of the Official Market whose mission one of which is to generate income and communities of Palembang Citywhich is located on Jl. K.H. Ahmad DahlanLantai II Pasar Bukit Kecil Palembang. The data used is financial statements that is the balance sheet and income statement in 2013-2015 through interviews and documentation.The purpose of this report is to know the management of the sources and uses of working capital at PD. Pasar Palembang Jaya. Based on the data obtained, the authors found several problems that PD. Pasar Palembang Jaya during the period 2013-2014 uses of working capital is greater than the source of working capital and the period 2014-2015 source of working capital is greater than uses of working capital. This shows the company has not been able to manage working capital as well as possible. The author gives advice to company that make better planning of the management of working capital on acquisition of working capital or the uses of working capital and improve the policies for management of working capital

No full textCritical proof load for proof load testing of concrete bridges based on scripted FEM analysis
No full textAs the bridge stock in The Netherlands and Europe is ageing, various methods to analyse the capacity of existing bridges are being studied. Proof load testing is one of the method to test the capacity of bridges by applying loads on the existing concrete bridges with small spans. Because of the fact that neither the actual traffic load nor the design traffic load required by Eurocode can be directly applied on the target bridge in real-life proof load testing, an equivalent wheel load has to be applied instead. The magnitude and the location of the equivalent wheel load is determined in such a way that it generates the same magnitude of inner forces in the cross section. Such calculation is usually done by linear finite element analyses (FEA). Whereas, different bridges have different geometry such as length, width, thickness, skewness, number of spans and lanes etc. For each configuration, FEA has to be done first to determine the loading position. The main aim of this paper is to study the relation between bridge geometry and unfavourable loading positions. Based on that, a guidance tool is developed for the determination of the critical proof load testing locations for the practice. To achieve this goal, a Python script has been developed using the general purpose FEM platform DIANA FEA. The script enables the automatic generation and analysis of a bridge model with different geometries and loading conditions. By applying the Eurocode Load Model 1 (LM1) at variable locations, the most unfavourable loading positions for the proof load are obtained at the corresponding boundary conditions. The output of the study provides a convenient tool for future proof load testing.Concrete Structure
