We should complete customized products in specified time to implement smart factories. For this simulation can work as a tool for validating production schedule. We propose in the manuscript a simulation model for sewing machine and modeling tool for simulation of sewing process.
We report that control over the grain size and lateral growth of monolayer MoS2 film, yielding a uniform large-area monolayer MoS2 film, can be achieved by submitting the SiO2 surfaces of the substrates to oxygen plasma treatment and modulating substrate temperature in chemical vapor deposition (CVD) process. Scanning electron microscopy and atomic force microscopy images and Raman spectra revealed...
This paper proposes a hypothetical in-vehicle telematics interface comparison using a Cognitive-Computational Driving Model, which is prototype simulator that simulate both a driver and his vehicle in various driving scenarios. Results can be interpreted in terms of driving safety, interface efficiency, and other metric values. The use of CCDM in early design enables engineers to more wisely spend...
In multiple-input multiple-output (MIMO) broadcast channel, the lattice-reduction-aided (LRA) precoder is the modified zero-forcing beamforming (ZFBF) scheme which perturbs data symbols to reduce the transmit power. In this paper, we propose the optimal user group selection (UGS) scheme for the LRA-precoder to maximize the sum-rate in MIMO broadcast systems. We derive the approximated sum-rate of...
Abstract—Hierarchical cell structure (HCS) is considered as a possible solution to support users in shadowing area or hot zone area. In HCS systems, both co-channel interference and mobility management are the most important problems. In this paper, we propose a new mobility management method that efficiently preserves the data rate of the mobile user passing small overlaid cell area. In the proposed...
