能不能研发一款能够读懂购买者需求的床垫,改变长期以来人们努力读懂选择床垫的局面?”——随着物联网的兴起,大数据、云计算、5G、人工智能等技术的不断革新,这种可能性转化为了现实。床垫龙头喜临门近日在上海发布了新型智能床垫“Smart 1”,其内在的“Smart Wave”系统将读懂用户对于床垫的需求。
We propose a novel multi-photon evanescent wave (MPEW) excitation modality for upconverting nanoparticles (UCNPs) based microscopy. Experimental results show this new imaging method for UCNPs is nonsc...
Security with the wave of a wand     Security  wave of a wand       2016/3/2
Increasingly, health care is moving out of the doctor's office and into the home, allowing greater patient freedom and monitoring, but also giving rise to new security risks.One of the main challenges...
Background: Kidney stones were previously rare among children, but now its prevalence and frequency among children has increased. Objectives: The aim of this study was to investigate the effect of a ...
A wave rotor is proposed for use as a constant volume combustor. A novel design feature is investigated as a remedy for hot gas leakage, premature ignition, and pollutant emissions that are possible i...
Control of leakage within wave rotors is recognized as a key requirement for efficient operation. Previous studies suggest that experimentally observed performance degradation is substantially due to ...
The objective of this paper is to provide a succinct review of past and current research in developing wave rotor technology. This technology has shown unique capabilities to enhance the performance a...
For some decades, efforts have been made to exploit nonsteady combustion and gas dynamic phenomenon. The theoretical potential of nonsteady-flowmachines has led to the investigation of various oscilla...
Significant performance enhancement of microturbines is predicted by implementing various wave-rotor-topping cycles. Five different advantageous cases are considered for implementation of a four-port ...
The wave rotor combustor can significantly improve gas turbine engine performance by implementing constant-volume combustion. The periodically open and closed combustor complicates thermodynamic analy...
A procedure to design a preliminary wave rotor cycle for any application is presented. To complete a cycle with heat addition there are two separate-but related-design steps that must be performed. Se...
A wave rotor may be used as a pressure-gain combustor, effecting wave compression and expansion, and intermittent confined combustion, to enhance gas-turbine engine performance. It will be more compac...
Combustion within the channels of a wave rotor is examined as a means of obtaining pressure gain during heat addition in a gas turbine engine. Three modes of combustion are assessed: premixed autoigni...
Wave rotor cycles that utilize premixed combustion processes within the passages are examined numerically using a one-dimensional CFD-based simulation. Internal-combustion wave rotors are envisioned f...
The wave rotor is a promising means of pressure-gain for gas turbine engines. This paper examines novel wave rotor topping cycles that incorporate low-NOx combustion strategies. This approach combines...
