Effect of earthquake directional uncertainty on the seismic response jacket-type offshore platform

Strengthening of columns using concrete jackets depends on friction at the interface between them. So strengthening edge and corner in only one story needs a large cross section area due to shortage length which leads architectural issues. This research aims study Jacket more than increases original column. As result, load transferred from column jacket will be increased. Thirteen models were d...

The sensitivity of the seismic response parameters to the uncertain modeling variables of pile-founded fixed steel jacket platforms are investigated using the Tornado diagram and the first-order second-moment techniques. The effects of both aleatory and epistemic uncertainty on seismic response parameters have been investigated for an existing offshore platform. The sources of uncertainty consi...

The aim of this study is to discover the characteristics of the cooling water in the cylinder head of a high-power diesel engine by using the Computational Fluid Dynamics (CFD). A 3-D geometric model of a cylinder head water jacket was previously constructed using Unigraphics software. A mesh was then imposed on the model using the preprocessor of Fluent software, GAMBIT. Three types of thermal...

We review our recent work on Yb-doped and hybridstructured solid photonic bandgap fibers (Yb-HS-SPBGFs) for linearlypolarized fiber lasers oscillating in the small gain wavelength range from 1160 nm to 1200 nm. The stack-and-draw or pit-in-jacket method is employed to fabricate two Yb-HS-SPBGFs. Both of the fiber shows optical filtering property for eliminating ASE in the large gain wavelength ...

When Stanley Kubrick first met his co-writer for the screenplay Full Metal Jacket, Kubrick asked him if he was familiar with “the concept of Jung” and “the concept of the Shadow, of our hidden side” (Herr 6). This fascination with the Jungian archetypes of order and chaos permeates throughout the film Full Metal Jacket in the plot, mis-en-scene, and cinematography. Furthermore, Kubrick takes th...

To improve the treatments for low back pain, new designs of total disk replacement have been proposed. The question is how well these designs can act as a functional replacement of the intervertebral disk. Four finite element models were made, for four different design concepts, to determine how well they can mimic the physiological intervertebral disk mechanical function. The four designs were...

The homologous venom allergen Ag 5s from the yellow jacket (Vespula vulgaris) and paper wasp (Polistes annularis) have 59% sequence identity of their respective 204 and 205 amino acid residues, and they have low degrees of antigenic cross-reactivity in insect allergic patients and in animal models. Hybrids containing different segments of these two vespid Ag 5s were expressed in yeast. Circular...

This paper is the result of research and contemplation on the actual usefulness of topology-based methods in real-world applications. We recapitulate commonly used arguments in favor of topology-based approaches first to realign our expectations with respect to the utilization of topology extraction in the context of concrete applications. To illustrate some of our considerations, we take a clo...

The fate is described of 11 patients who had a stored pulmonary valve homograft mounted on a frame or in a Dacron jacket used for mitral valve replacement. Mitral regurgitation due to holes in the attenuated cusps occurred in nine by one year, requiring re-operation or causing death. Only one patient remains well with moderate mitral regurgitation after two years. Since January 1967, 118 patien...
