Fuzzy consequence modelling of hydrocarbon offshore pipeline

M. Kasaeyan; J. Wang; I. Jenkinson; M. R. Miri Lavasani

Volume 1, Issue 1 , December 2011, Pages 3-12

  The traditional event tree analysis uses a single probability to represent each top event. However, it is unrealistic to evaluate the occurrence of each event by using a crisp value without considering the inherent uncertainty and imprecision a state has. The fuzzy set theory is universally applied to ...  Read More

The layered structure in exchange flows between two basins (Middle and Southern basins of the Caspian Sea)

A. A. Bidokhti; A. Shekarbaghani

Volume 1, Issue 1 , December 2011, Pages 13-22

  Ocean waters often show layered structures especially where exchange flow between two basins occurs. These structures are often attributed to processes such as double.diffusive convection, internal waves, turbulent modulated mixing. In this paper by examining the vertical structures of temperature, salinity ...  Read More

Application of Fuzzy Fault Tree Analysis on Oil and Gas Offshore Pipelines

M. R. Miri Lavasani; J. Wang; Z. Yang; J. Finlay

Volume 1, Issue 1 , December 2011, Pages 29-42

  Fault Tree Analysis (FTA) as a Probabilistic Risk Assessment (PRA) method is used to identify basic causes leading to an undesired event, to represent logical relation of these basic causes in leading to the event, and finally to calculate the probability of occurrence of this event. To conduct a quantitative ...  Read More

S. Rahmani; P. Ghavam Mostafavi; M. H. Shahhosseiny; Gh. Vosoughi; A. Faraji

Volume 1, Issue 1 , December 2011, Pages 43-50

  Coral reefs which form some of the most diverse ecosystems on Earth support many symbiotic relationships. Symbiodinium can provide up to 90% of a coral.s energy requirements. Temperature rise, turbid water and high salinity in the Persian Gulf were among the factors separating zooxanthellae from corals ...  Read More

A survey on the accumulation of heavy metals as indicator of oil pollution index (Vanadium and Nickel) in bivalve rock oyster (Saccostrea cucullata) in Qeshm Island coasts

A. Mashinchian Moradi; M. Jalali Mosallam; M. R. Fatemi

Volume 1, Issue 1 , December 2011, Pages 51-58

  In this study, the amount of nickel and vanadium elements in the soft tissues of rock oysters (Saccostrea cuculata) and sea water from coastal areas of Qeshm Island, the biggest island of Persian Gulf located in the south of Iran, were measured to evaluate the contamination of the aquatic environment ...  Read More

Feasibility Study of Building a Human Powered Hydrofoil Vessel

F. Azarsina

Volume 1, Issue 1 , December 2011, Pages 59-68

  In this paper, a feasibility study of building a Human Powered Hydrofoil (HPH) vessel is reported. Hydrofoil vessels are a well-known class of high-speed crafts. In addition to high-speed operation, the hydrofoils have a reliable maneuvering capability, good stability and proper operation in waves. Also, ...  Read More
