Computer‐aided fixture design (CAFD) techniques have been advanced so rapidly that computers can now generate configurations automatically, for both modular fixtures and dedicated fixtures. verification (CAFDV) is the verifying improving existing designs. It verifies followings: geometric constraining ability, achieved tolerance, fixturing stability, accessibility. Two models – one kinematic are created verification.
Thin-film lithium niobate on insulator (LNOI) has recently emerged as a promising platform for high-speed optical communication devices.For practical applications, an efficient, polarization-insensitive, misalignment-tolerant and broadband fiber-to-chip coupler is necessary.In this paper, we present edge based trident spot-size convertor (SSC).Experiment shows 1.18/1.10dB per facet low loss at 1550 nm TE/TM polarization respectively.A relatively large alignment tolerance (AT) also been...
WeChat (Tencent) is one of the most important information sources for Chinese people. Relevantly, various health-related data are constantly transmitted among users. public accounts (WPAs) health rapidly emerging. Health-related have a significant impact on health. Because rise in web-based health-seeking behavior, general has grown accustomed to obtaining cancer from WPAs. Although WPAs make it easy people obtain information, quality questionable.
This paper fundamentally investigates the peak-to-average power ratio (PAPR) theory in all optical orthogonal frequency division multiplexing (OFDM) systems which employ intensity modulation-direct detection (IM-DD) scheme. We propose a low-complexity PAPR reduction scheme based on phase pre-emphasis. Simulations show that proposed brings about 3.74 dB and better nonlinear impairment tolerance 16x10Gb/s IM-DD OFDM system.
Fixturing is an important manufacturing activity in the production cycle. The computer-aided fixture design (CAFD) technique has been developed and become part of CAD/CAM integration. CAFD consists three major aspects: setup planning, configuration design. An automated modular system applied to industrial practice. This paper focuses on a technical problem involved development planning systems, that is, accessibility analysis fixturing surface workpiece. should be correctly assessed reflect...
This study investigated the mechanical properties and dry-sliding friction wear behaviors of graphene-reinforced TiAl matrix composites in expectation providing valuable information for application graphene. The results suggested that incorporation graphene apparently improved microhardness, fracture toughness, tribological composites. For composite with 3 wt% graphene, microhardness increased by 129%, toughness 149%, coefficient decreased 37% rate 78%. Also, microstructural analyses worn...
An experimental system consisting of a spherical vessel with horizontal pipe was established. By changing the length, effect that ignition position has on methane explosion in an airtight studied, and regularities Pmax, (dP/dt)max flame transmission were analyzed detail. The results show different leading to propagation pressure wave. As moved from wall end pipe, Pmax apparatus first increased, then decreased when occurs behind center vessel, finally increased middle pipe. same trend...
A frequency-reconfigurable antenna with mechanical tuning, providing the frequency tuning from 2.51 to 3.70 GHz, is presented. The design comprises a slot and novel metasurface (MS) isosceles triangular-loop unit cells. Through pivoting of MS, this achieved good performance in reconfiguration. Moreover, reconfigurable have advantages compact structure diameter 50mm height 3mm, radiation efficiency up 90% across tuning-range. Measured simulated results testify wide tunablity antenna,...
As a pillar industry with high energy consumption and low efficiency, the building of China has produced consistently carbon emission levels in recent years.The important goals coordinated development this include large-scale green buildings, use technologies to reduce emissions, an effective reduction intensity.Prefabricated buildings have become popular due their consumption, emission, pollution environment-friendly nature.This paper examines those factors that influence emissions from...
To study the effects of hardness and Reynolds number on fouling calcium carbonate under a low number, experimental method principle for determining thermal resistance were analyzed theoretically. The device whole heat transfer was designed. By changing concentration in fluid, process at studied. results show that will reach fixed value over time, is, asymptotic resistance. In case constant increased exponentially, approximately. When constant, growth rate increased, with decreasing number....
Polarization characteristic is an important feature of electromagnetic (EM) wave. Manipulating polarization state and controlling propagation direction EM wave by phase-gradient metasurface (PGM) have become a research hotspot in recent years. However, using transmissive PGM for manipulation often suffers low efficiency. To alleviate this problem, multilayered structure was utilized. it suffered bulky volume design complexity. Therefore, engineering thin high-efficiency with pressing...
An online degradation model is presented, in which avoided the error parameter accelerated test, caused by temperature shock during measurement. Through measurement with avoiding parameter, can be more accurate. To demonstrate application of method, a kind mature product, 3CG120, tested range 150230 ℃ under process-stress. Then lifetime obtained utilizing to about 6.5%, much less than that old (23.2%).
