Abstract: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

Abstract: The present disclosure discloses an amino acid helical array film and a preparation method thereof. The amino acid helical array film comprises a substrate and an amino acid helical array uniformly deposited on the substrate. Each amino acid helix is obtained by self-assembling an amino acid with a modifying group. The amino acid is selected from one or more of twenty common natural amino acids or adjacent isomers thereof. The modifying group comprises an N-terminal protecting group and a C-terminal protecting group, wherein the N-terminal protecting group is selected from one or more of carbobenzoxy, a lipid group, t-butoxycarbonyl, and 9-fluorenylmethoxycarbonyl, and the C-terminal protecting group is selected from one or more of nitrophenyl ester, a lipoxy group, and an acylamino group.

Abstract: Disclosed is a method for short-term traffic risk prediction of road sections by using roadside observation data.

Abstract: The present invention discloses a method of constructing a high-frequency vibratory stress relief device for eliminating residual stress of a small work-piece.

Abstract: A multi-channel circuit having respective channels powered through transformers having primary windings connected in series allows substantially equal constant currents to be provided through all channels by cross-regulation while only a single channel need be monitored and controlled. The variation in current between channels is generally small and largely insensitive to imbalances between voltages on loads due, for example, to different numbers of LEDs in series connected strings in illumination devices and can be further reduced by inverse coupling between inductors in respective channels. Efficiency is improved through reduction in the number of stages of the constant current source since the respective channels provided both DC-to-DC conversion and constant current regulation.

Abstract: A method and apparatus for transforming large messages using a scalable process. This scalable process decomposes the message into nodes and node values. Navigation between related tree node tree is carried out based upon the decomposed message. Following decomposition a first node to be transformed is retrieved. Following retrieval of the first node a second node to be transformed is requested. The process obtains the node from the node files. This process repeats until the message is transformed.
