The selection of seismic attributes is a key process in reservoir prediction because the prediction accuracy relies on the reliability and credibility of the seismic attributes. However, effective selection method for useful seismic attributes is still a challenge. This paper presents a novel selection method of seismic attributes for reservoir prediction based on the gray relational degree (GR...

Buried steel fuel pipelines are critical lifelines for the society and the economy but are very vulnerable to earthquake-induced ground failure. Traversing seismic areas inevitably results in several pipe-fault crossings. Fault rupture forces a buried pipeline to undergo deformations that could be substantial and heavily endanger its integrity. Due to the grave consequences of a potential pipe ...

The overall achieved transmission for carbon ions through the injector linac at the Heidelberg ion therapy HIT did not ecxeed 30 % due to a mismatch of the beam at the RFQ entrance [1]. Thus a detailed upgrade programm has been started to exchange the RFQ with a new input radial matcher (IRM) design, to correct the misalignment and to optimize beam transport to the IHDTL. The aim is to achieve ...

The LHCb experiment has been designed to perform precision measurements of CP asymmetries and to investigate potential effects of physics beyond the Standard Model. Results obtained from data collected in 2010 and 2011 show that the detector is robust and functioning well. While LHCb will be able to measure a host of interesting channels in heavy flavour decays in the coming years, a limit of a...

The LHCb experiment will operate for about five years at a luminosity of 2 × 10 cms and plans are to accumulate a data sample of ∼ 10 fb. Here we present the physics programme and detector design for a future high luminosity phase of the LHCb experiment. An upgraded LHCb experiment would operate at ten times the design luminosity, i.e. at ∼ 2×10 cms and aims to collect a data sample of ∼ 100 fb...

Obtaining seismic images with good quality in hardrock environments has been challenging. This condition applies to many mineral explorations using seismic methods including our study area where the data quality is strongly affected by soft, near-surface materials and a reflector with low contrast in rock physical properties. Until recently, no effective processing has been applied to the seism...

If you are running a metadata server in your SAS ® 9.1.3 environment, you must upgrade your metadata when you move to SAS ® 9.2. There are two possible approaches to take. The first approach is a migration, which will essentially copy your SAS 9.1.3 environment over to SAS 9.2 as part of your SAS 9.2 installation process. The second approach is to make a fresh start by installing SAS 9.2 first,...
