The present note describes a machine development (MD) aimed to confirm experimentally the need for protection of the extraction wire septum ZS in SPS long straight section LSS6 [1] during LHC operation. Single wires identical to the ones mounted on the extraction septum were fixed on a fast wire scanner and put into the beam path. The beam heated the wire until it broke after a measured number ...

          USD7 is one of the steel products of Isfahan Steel Company. It is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. Finally, it is wire drawn up to 3 mm and used as welding electrodes. This steel contains 0.05 to 0.09 wt. % carbon. The acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. Therefore, it is categorized as rimmed steel...

Trace elements of quartz document the physical-chemical evolutions growth, which has been a great and most applied tool in study geological settings quartz-forming environments. A classic method is using graphic diagram plots visualizing trace element discriminations trends, examples including Al-Ti (Rusk, 2012, https://doi.org/10.1007/978-3-642-22161-3_14) Ti-Al-Ge (Schrön et al., 1988, https:...

Introduction: A bullet type sampler is sometimes used to obtain a sample from an asteroid on samplereturn missions [1]. On the other hand, in-situ analysis is demanded for the investigation of more amount of rock samples. Many drilling or coring devices have been developed [2-5]. Slicing the rock sample is preferable to observe its interior rather than shaving [6]. Because coolant cannot use in...

A key challenge for Machine Translation is transfer selection, i.e. to find the right translation for a given word from a set of alternatives (1:n). This problem becomes the more important the larger the dictionary is, as the number of alternatives increases. The contribution presents a novel approach for transfer selection, called conceptual transfer, where selection is done using classifiers ...

We first present a unged formulation to three problems in VLSI physical design: Layout compaction, Wire balancing and Integrated layout compaction and wire balancing problems. The aim of layout compaction is to achieve minimum chip width. Whereas wire balancing seeks to achieve minimum total wire length, integrated layout compaction and wire balancing seeks to minimize wire length maintaining t...

background: human error is the most important cause of occupational and non-occupational accidents. because, it seems necessary to identify, predict and analyze human errors, and also offer appropriate control strategies to reduce errors which cause adverse consequences, the present study was carried out with the aim of identifying human errors while operating meat grinder and offer suggestions...

Rapid prototyping (RP) methods are used for production easily and quickly of a scale model of a physical part or assembly. Gas metal arc welding (GMAW) is a widespread process used for rapid prototyping of metallic parts. In this process, in order to obtain a desired welding geometry, it is very important to predict the weld bead geometry based on the input process parameters, which are voltage...

Abstract The theoretical analysis and numerical simulation are combined to explore the generation mechanism propagation characteristics of shock wave in WEIF process. results show that with increase linear density deposition energy, distance same time is longer; as increases, velocity on front gradually decreases. In early stage electric explosion metal wire, shape generated expansion evolution...
