Introduction: rapidly growing volumes of information pose new challenges to modern data analysis technologies. Currently, based on cost and performance considerations, processing is usually performed in cluster systems. One the most common related operations analytics joins datasets. Join an extremely expensive operation that difficult scale increase efficiency distributed databases or systems ...

Korea is responsible for the procurement of the ITER first wall (FW) blanket modules 1, 2 and 6, and has been developing the fabrication technology of them. Joining Be, CuCrZr and stainless steel (SS) is the most important aspect of the FW and to derive the optimum joining conditions, several mock-ups with various temperatures and pressure conditions between CuCrZr, and SS and with various inte...

The data presented in this article are related to the research article entitled: "Solder free joining as a highly effective method for making contact between thermoelectric materials and metallic electrodes" (Malik et al., 2017) [1]. This article presents microstructure obtained by scanning electron microscopy (SEM) and chemical analysis by energy dispersive X-ray spectroscopy (EDX) point measu...
