Researches were conducted on the laser welding of 3 mm sheet-thickness lap joints of AA5052 with ER4043 filler wires.The effects of laser power on the joint morphology, microstructure, DMSO mechanical properties, and corrosion resistance were investigated.The results indicate that both increased heat input and the addition of filler wires make the

In this paper, we introduce the concept of multi-dimensional (MD) space-time shift keying (STSK) for improving conventional STSK schemes, while still maintaining the general STSK structure for backward compatibility.Firstly, we design two transmission modes for three-dimensional (3-D) STSK schemes, DMSO referred to as R2 3-D STSK and R3 3-D STSK, w

Abstract Background Eighty-three strains of Leuconostoc mesenteroides were isolated from Algerian raw camel milk.Based on morphological, biochemical, and physiological characters tests, strains were identified as Ln.mesenteroides subsp.mesenteroides.Seven strains had a remarkable antagonistic and probiotic characterization.The present study aims at

This paper deals with the results of study on implementing reduced impact logging (RIL) as well as conventional logging (CL), which was carried out in natural production forest under the concession operation of a forest company in Riau in 2001.The aim of this study was EB Archive to assess the effect of reduced impact logging on possible improvemen

A new image enhancement algorithm employing guided filtering is proposed in this work for enhancement of solar images and videos, so that users can easily figure out important fine COLON CARE structures imbedded in the recorded images/movies for solar observation.The proposed algorithm can efficiently remove image noises, including Gaussian and imp
