Abstract:

SaaS (Software as a Service) application mode came into being along with the expansion and convenient of the network platform, and its core lies in Multi-Tenant (multi-tenant) application. Multi-Tenant Application under the SaaS model makes software applications efficient and convenient, more importantly, tenants can greatly reduce their software development costs, hardware acquisition costs, training costs, and upgrade and maintenance costs by using the application system, which virtually eased business cost pressures and makes more focus on business development.

Abstract:

Interference within a multi-core architecture may have several origins. Understanding where interference comes from is mandatory for verification and certification purposes. Unfortunately, the complexity of current architectures makes it difficult to quantify such interference. In this article, a new approach is introduced that enables benchmark configurations to isolate and quantify interference. An experiment with DMA interference is presented and shows a WCET overhead of up to 0.26% at 25 Mbit/s. This experiment was also able to discover and identify interference related to DMA, such as int

Abstract:

Energy optimization is an increasingly important aspect of today’s high-performance computing applications. In particular, dynamic voltage and frequency scaling (DVFS) has become a widely adopted solution to balance performance and energy consumption, and hardware vendors provide management libraries that allow the programmer to change both memory and core frequencies manually to minimize energy consumption while maximizing performance. This article focuses on modeling the energy consumption and speedup of GPU applications while using different frequency configurations. The task is not straigh

Abstract:

Most spoilers are made from a sandwich structure with a honeycomb component as its core. However, the honeycomb core is sensitive to water ingress, causing damage to the control surface due to its weak moisture-resistance behavior. This study aimed to conduct the design and analysis of an improved composite structure for a coreless spoiler. A spoiler design of an aircraft, the A320, was used for the case study. The weaknesses of a coreless spoiler were identified through finite element analysis via Abaqus software. Multi-spar and multi-rib designs were studied and compared for topological opti

The results showed that the major reason of core breaking occurs was that the tensile stress was bigger on the center than the edge of Bi-2212 wires during the drawing, and the silver-superconductor ratio was smaller of the center than the edge of the traditional Bi-2212 wires. It was effective to avoid the core breaking of Bi-2212 wires using the Ag core strengthener, and the uniformity of distortion of Bi-2212

Peak power single-handedly determines the involved cooling costs in many-cores, while its violations could induce performance-crippling execution uncertainties.

Abstract:

The success or failure of a solver is oftentimes closely tied to the proper configuration of the solver's parameters. However, tuning such parameters by hand requires expert knowledge, is time consuming, and is error-prone. In recent years, automatic algorithm configuration tools have made significant advances and can nearly always find better parameters than those found through hand tuning. However, current approaches require significant offline computational resources, and follow a train-once methodology that is unable to later adapt to changes in the type of problem solved. To this end, thi

Abstract:

Abstract Spatial division multiplexed optical transmission over a multi-ring-core orbital angular momentum (OAM) fibre is reported for the first time. The seven cores in the fibre each supports OAM modes belonging to mode groups (MGs) of topological charge |l| = 0–4. The MGs of |l| = 1–4 each contains four near-degenerate OAM modes that carry the combinations of opposite orbital and spin angular momenta. The weak coupling between these higher-order MGs as well as between the cores enables the simultaneous transmission of 56 OAM mode channels (two MGs per core of the topological charges |l| = 2

Abstract:

We propose a thread-based modeling and analysis method for a vehicle-to-everything (V2X) communication device, according to the performance requirements of the V2X application. For a developer to develop a V2X device or application, its performance requirements must first be determined. Furthermore, the developer selects the hardware system to enable the service to function while satisfying the performance requirements. Through this process, the developer designs and creates the program in a manner that considers thread configuration and core mapping with the given hardware resources. Then, th

Abstract Controlled synthesis of core@shell nanoparticles (NPs) for certain applications is a difficult challenge in many nanotechnology projects. In this report, a conventional arrangement composed of a gas aggregation source (GAS) is employed to generate the core NPs, which are subsequently coated by the shell materials in a secondary planar magnetron sputtering. The important difference to the usual system is the application of the two opposing planar magnetrons in a closed field configuration. The prepared core Ag NPs by a GAS are coated/treated by the two magnetrons with Ti targets. Our f
