Previous studies have shown that the crosswind reduces output power of a SCPP (solar chimney plant) with deflection plume at exit and separation wind flow there downstream. The present numerical investigation was focused on effect stack configuration performance SCPP. In this paper, prototype in Manzanares simulated, where Boussinesq approximation used for solving continuity, Navier–Stokes ener...

A wide range of existing power technologies can make use of the solar energy reaching Earth. Basically, all those ways can be divided into two basic categories: transformed for use elsewhere or utilized directly – direct – and involving more than one transformation to reach a usable form – indirect. The Solar Chimney Power Plant (SCPP) is part of the solar thermal group of indirect solar conver...

optimal attributes are useful in interpretation of seismic data. two proposed methods are presented in this paper for finding optimal attributes. regularized discriminate analysis(rda) is based on 2 parameters ë, ? which called regularization parameter. the other method is principal component analysi s(pca).in this paper gas chimney detection is defined as the subject of study for ranking relev...

The Lost City Hydrothermal Field, an ultramafic-hosted system located 15 km west of the Mid-Atlantic Ridge, has experienced at least 30,000 years of hydrothermal activity. Previous studies have shown that its carbonate chimneys form by mixing of approximately 90 degrees C, pH 9-11 hydrothermal fluids and cold seawater. Flow of methane and hydrogen-rich hydrothermal fluids in the porous interior...

Traditional methods of adjustment for multiple comparisons (e.g., Bonferroni adjustments) have fallen into disuse in epidemiological studies. However, alternative kinds of adjustment for data with multiple comparisons may sometimes be advisable. When a large number of comparisons are made, and when there is a high cost to investigating false positive leads, empirical or semi-Bayes adjustments m...

J Endovasc Ther 2013;20(2):159e69. 22 Banno H, Cochennec F, Marzelle J, Becquemin J-P. Comparison of fenestrated endovascular aneurysm repair and chimney graft techniques for pararenal aortic aneury...

Industrial structures built with different materials and methods play an important role in the sector development of industry increase energy need. Many parameters are considered design application phase industrial to provide service for many years. The aim this study is examine dynamic behavior reinforced concrete chimneys depending on soil-structure interaction (SSI). For reason, a chimney, w...

Renal artery obstruction during endovascular repair of abdominal aortic aneurysm using standard device is a rare but life-threatening complication and should be recognized and repaired rapidly in order to maintain renal function. Both conventional surgery and endovascular stenting have been reported. We report a case of late postoperative bilateral "chimney" to resolve a bilateral thrombosis of...

W ea th er – Ju ly 20 10 , V ol . 6 5, N o. 7 fog, but the north tower had a story to tell. It worked as a chimney. The fog entered and escaped through the openings of the tower, displaying iridescent colors and creating ever-changing and fast-moving fog shadows of the tower and the cables (Figure 2). I emailed a few images to Dr Andrew T. Young at the Astronomy Department, San Diego State Univ...
