Introduction When it comes to a fast, non-intrusive, complete and meaningful inspection of an offshore pipeline in-line inspection (ILI) has been the method of choice for several decades now. However, not all pipelines, piping or other tubular structures can be inspected with in-line inspection tools (pigs). The method is usually limited to looping flow lines or export pipelines, specifically d...

The design of electrical wiring and hydraulic/pneumatic piping routes in aircraft is a long and repetitive process which is largely done by hand. Presented in this paper is progress in the development of a knowledge based routing system which automates much of the routing process using intelligent algorithms and interchangeable design rules. The system reads three dimensional CAD models to be n...

Abstract Piping systems are common in many architectures and designing such is often a complex task. Design automation of piping therefore universal research subject. Nonetheless, these still designed by hand as result their complexity. Consequently, costs associated with design high, especially for large-scale like ships chemical plants. The goal automatic pipe routing to reduce the time syste...

Ghost crabs (Ocypode quadrata) have been implicated in mortality of eggs and chicks of the beach-nesting Piping Plover (Charadrius melodus) whose Atlantic Coast populations are listed as threatened. Through observation and experimentation, we investigated the interactions between ghost crabs and plovers on Wild Beach, a Piping Plover nesting area on Assateague Island, Virginia. This site has a ...

The joint general model of reliability and availability of complex technical systems in variable operation conditions linking a semi-markov modeling of the system operation processes with a multi-state approach to system reliability and availability analysis and linear programming considered in the paper Part 1 are applied in maritime industry to reliability, risk and availability optimization ...

Tanah lempung adalah tanah yang memiliki partikel-partikel mineral tertentu dimana didalamnya terdapat partikel lanau maupun pasir dan mungkin juga campuran bahan organik. Jenis ini daya dukung kurang baik kondisi tersebut tidak memungkinkan untuk dibangun konstuksi jalan raya diatasnya. Perlu dilakukan upaya memperbaiki salah satu cara paling umum digunakan melakukan stabilisasi diambil di Des...

Perencanaan pembangunan Bendungan Pidekso di Kabupaten Wonogiri dengan tipe bendungan urugan berkemungkinan gagal. Salah satu kerusakan yang terjadi adalah rembesan. Terjadinya rembesan dapat menyebabkan terbentuknya pipa-pipa dalam tanah. Tujuan dari adanya penelitian ini yaitu untuk mengetahui perbedaan debit sebelum dan sesudah grouting serta faktor keamanan piping. Metode digunakan berupa p...
