J. P. Vigneronon is essential for selecting between alternative providers. Existing methods typically assess reputation on a combination of direct experiences by the client being provided with a service and third party recommendations, but they exclude from consideration a wealth of information about the context鞭子 发表于 2025-3-27 07:14:12
D. van Labeke,D. Barchiesid providers need to compete against each other to maximize their profits by setting cloud resource prices based on their pricing strategies. In this paper, we analyze how an auction-based cloud provider sets the auction price effectively when competing against other cloud providers in the evolutionamaverick 发表于 2025-3-27 10:16:48
Near Field Optical and Exciton Imaging, Spectroscopy and Chemical Sensorsofabrication, has been developed, leading to a thousandfold miniaturization of immobilized Fiber Optical Chemical Sensors and to a billionfold decrease in necessary sample volume. Submicrometer pH sensors have been prepared by attaching a copolymer covalently to an activated nanofabricated fiber tip没有贫穷 发表于 2025-3-27 14:26:43

Reflection Shear Force/Near-Field Scanning Optical Microscopy (NSOM)eparation. Combining scanning force microscopy with NSOM allows one to maintain a small tip-sample separation distance and, consequently, improve NSOM resolution. This provides, simultaneously, a topographic perspective of the sample as well as an NSOM image. We present in this paper an instrument tacrimony 发表于 2025-3-28 04:43:52
Optical Tunneling through an Adjustable Liquid Metal Gape considered a photon tunneling process. As to be expected on theoretical grounds, we find that the transmission vs. gap width varies on a scale of 5 to 10 mm, which is much more rapid than in any other NFO scheme. A correspondingly high lateral resolution may be anticipated. Successful operation ofCOM 发表于 2025-3-28 06:36:13

Combination of a Fiber and a Silicon Nitride Tip as a Bifunctional Detector; First Results and Persptor. The optical signal detected by the tip is transmitted by the fiber towards a photomultiplier. Simultaneously or sequentially, the topography of the object is measured by means of a second beam reflected on the cantilever. For discriminating the two signals, each beam is modulated at a given fre
