Abstract: The invention discloses a bionic laminated thermal insulation material, which imitates a multi-thin laminated and thin-layer micro-pore structure of Sequoia sempervirens bark with fire resistance, corrosion resistance and excellent thermal insulation performance. A low thermal conductivity microporous powder is used as main raw material, while reinforcing agent, plasticizer and porosity agent are added to form microporous thin-layer units, and each thin-layer unit is bonded and laminated to make a laminated thermal insulation material. The thermal conductivity of the finished products is as low as 0.02˜0.05 W/m·k, with good thermal insulation and mechanical properties, which can be used in a temperature range below 1000° C., with better thermal insulation and energy-saving effect and toughness than ordinary thermal insulation materials, significantly reducing the thickness of the insulation layer, and can be widely used in industrial furnaces, thermal engineering devices, insulation pipes and other fields.

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 invention provides an efficient ultrasonic phased array phase shift migration imaging method for the defect in a multi-layer structure, including the following steps: (1) transforming full matrix capture data of a multi-layer structure to a frequency-wavenumber domain by means of three-dimensional fast Fourier transform; (2) for any non-traversed layer in the multi-layer structure, extrapolating a surface wave field of the multi-layer structure to an upper interface of the non-traversed layer, to obtain wave field information of the non-traversed layer; (3) according to the obtained wave field information, performing focus imaging on the non-traversed layer in the frequency-wavenumber domain; and (4) repeating the steps (2) and (3), until all layers are traversed, to obtain an imaging result of the multi-layer structure.

Abstract: The invention is a method for the treatment of cancer comprising interactive imaging techniques to optimize the placement of radioactive seeds in a portion of the body containing cancer. The method comprises the computer assisted development of a seed placement plan based on images obtained on a pre-operative day. Seeds are placed into the region of interest in the body, typically the prostate, using an ultrasound guided method. The seeds are imaged using computed tomography (CT) to assess the dose distribution. A second plan, or miniplan, is developed based on information obtained in the CT scan. Additional ultrasound-guided seeds are placed at the same procedure based on the miniplan to optimize the final dose coverage.
