Steel-structured jacket or template platforms have been extensively installed in Persian Gulf offshore oil & gas fields. For the jackets in the water depth range of 40 meters in this region, utilizing the self-upending concept has been investigated. It has been concluded that designing the light weight jackets, implementing the self-upending process for their installation operations, are econom...

This study investigates the seismic response of a horizontal axis wind turbine on two bottom-fixed support structures for transitional water depths (30-60 m), a tripod and a jacket, both resting on pile foundations. Fully coupled, nonlinear time-domain simulations on full system models are carried out under combined wind-wave-earthquake loadings, for different load cases, considering fixed and ...

Due to the efficiency in implementation, the Walsh (Hadamard) transform plays an important role in signal analysis and communication. Recently, Lee generalized the Walsh transform into the Jacket transform. Since the entries of the Jacket transform can be ±2, it is more flexible than the Walsh transform. Both the Walsh transform and the Jacket transform are defined for the case where the length...

[Purpose] The purpose of this study was investigated the effect of tight clothes on cervical and thoracic spine muscles activities during shoulder abduction. [Subjects and Methods] The subjects of this study were 10 healthy males. The subjects performed two shoulder abduction trials for each of two jacket-wearing conditions. The right upper, middle, and lower trapezius and serratus anterior mus...

Indefinites in intensional contexts, such as attitude reports or intensional argument positions, give rise to a well-known ambiguity. Consider (1): On the so-called specific reading, it says that there is a particular object which happens to be a jacket like Malte’s jacket such that Adrian wants to buy that particular object. Adrian need not know that that object is a jacket like Malte’s. On th...

Laboratories and test houses keep a "pool" of test subjects that volunteer to be participants in life jacket approval testing, which is believed to be an incorrect procedure. Fifty-six participants donned 8 child/infant life jackets onto 4 infant manikins in random order with time and accuracy of donning recorded. Average donning time for all 8 life jackets decreased significantly after the fir...

Lightweight concrete (LWC) is a kind of concrete that made of lightweight aggregates or gas bubbles. These aggregates could be natural or artificial, and expanded polystyrene (EPS) lightweight concrete is the most interesting lightweight concrete and has good mechanical properties. Bulk density of this kind of concrete is between 300-2000 kg/m3. In this paper flexural strength of EPS is modeled...

1.1 Offshore Structures: Offshore structures used for oil and gas extraction have the common function of providing a safe, dry working environment for the equipment and persons those operates the platform. Jacket supported drilling equipment as a guide for the piled foundations. The substructure referred to as the jacket is a three dimensional space frame made from large tubular steel members. ...

Full Metal Jacket is a general-purpose visual dataflow language currently being developed on top of Emblem, a Lisp dialect strongly influenced by Common Lisp but smaller and more type-aware, and with support for CLOS-style object orientation, graphics, event handling and multi-threading. Methods in Full Metal Jacket Jacket are directed acyclic graphs. Data arriving at ingates from the calling m...
