Gmaw Welding

This paper proposes the development of the methodology to be carried out for the metal joining process through the GMAW welding process in the Fanuc LR Mate 200iD industrial robot. The parameters or properties were considered for the application to be as efficient as possible, such parameters as speed of application, characteristics of the filler material, gas to be used as welding protection. The GMAW welding process can be applied semiautomatically using a hand gun, in which the electrode is fed by a coil, or an automatic form that includes automated equipment or robots. The advantages and disadvantages of the GMAW welding process applied in a manual and automated way were commented. The mechanical properties of the materials to which said welding can be applied were investigated; The materials with which this type of welding can be worked are the high strength materials, which are used in the automotive industry, for the forming of sheet metal. To know the properties of the material, destructive tests were carried out on the test material to be used, as well as the mechanical properties of the welding.

AbstractRecently, the number of Internet of Things (IoT) devices connected to the Internet has increased dramatically as well as the data produced by these devices. This would require offloading IoT tasks to release heavy computation and storage to the resource-rich nodes such as Edge Computing and Cloud Computing. Although Edge Computing is a promising enabler for latency-sensitive related issues, its deployment produces new challenges. Besides, different service architectures and offloading strategies have a different impact on the service time performance of IoT applications. Therefore, this paper presents a novel approach for task offloading in an Edge-Cloud system in order to minimize the overall service time for latency-sensitive applications. This approach adopts fuzzy logic algorithms, considering application characteristics (e.g., CPU demand, network demand and delay sensitivity) as well as resource utilization and resource heterogeneity. A number of simulation experiments are conducted to evaluate the proposed approach with other related approaches, where it was found to improve the overall service time for latency-sensitive applications and utilize the edge-cloud resources effectively. Also, the results show that different offloading decisions within the Edge-Cloud system can lead to various service time due to the computational resources and communications types.

Abstract Cadmium sulfide and selenide pigments (cadmium pigments) belong to the inorganic yellow, orange and red pigments. Cadmium sulfide pigments are based on the wurtzite lattice, where cadmium can be partially substituted by zinc or mercury and sulfide by selenide. Cadmium pigments are characterized by excellent optical and application characteristics in particular regarding brightness of shade, hiding power, tinting strength, and weather fastness. The declining use of cadmium-containing materials in the last decades is a result of the environmental discussion and the development of less problematic substitute products, especially of bismuth vanadate and high-value organic, temperature-stable yellow and red pigments.

Hardware Efficiency

In current System-on-Chip (SoC) design, the main engineering trade-off concerns hardware efficiency and design effort. Hardware efficiency traditionally regards cost versus performance (in high-volume electronics), but recently energy consumption emerged as a dominant criterion, even in products without batteries. "The" most effective way to increase HW efficiency is to exploit application characteristics in the HW. The traditional way of looking at HW design tends to consider it a time-consuming and tedious task, however. Given the current lack of HW designers, and the pressure of time-to-market, clearly a desire exists to fine-balance the merits and effort of tuning your HW to your application. This paper discusses methods and tool support for HW application-tuning at different levels of granularity. Furthermore we treat several ways of applying reconfigurable HW to allow both silicon reuse and the ability to tune the HW to the application after fabrication. Our main focus is on a methodology for application-tuning the architecture of DSP datapaths. Our primary contribution is on reusing and generalizing this methodology to application-tuning DSP instruction sets, and providing tool support for efficient compilation for these instruction sets. Furthermore, we propose an architecure for a reconfigurable instruction-decoder, enabling application-tuning of the instruction-set after fabrication.

Der Fachbeitrag beschreibt die Weiterentwicklung von galvanisch einschichtig belegten grobkörnigen Diamantschleifscheiben – auch Engineered Grinding Wheels genannt. Verschiedene sprödharte Werkstoffe wurden anhand von Quer-Umfangs-Planschleifversuchen mit angestellter Probenoberfläche bearbeitet. Anhand der Oberflächenqualität und der Bauteilrandzone wurde anschließend der Einfluss einer variierten Zustellung sowie der Prozesskinematik auf einen duktilen Schleifprozess untersucht.   This study describes the application of coarse-grained diamond grinding wheels with electroplated abrasive single-layers (engineered grinding wheels) for ductile mode grinding of different brittle materials. Grinding experiments were performed in cross grinding kinematics while the workpiece is tilted in order to achieve different depths of cut over the workpiece’s surface. Influence of kinematics and depth of cut are investigated by measuring surface roughness and subsurface damage.
