Abstract: Disclosed herein are methods and systems that use a photonic crystal (PC) for interference scattering microscopy. Incident light is directed onto a surface of the PC and couples into a photonic crystal guided resonance (PCGR) mode of the PC such that less than 1% of the incident light is transmitted through the PC as transmitted light. One or more particles adjacent to the surface of the PC scatter a portion of the light coupled into the PCGR mode as scattered light. An image comprising a pattern of constructive and destructive interference between the transmitted light and the scattered light is formed, and an image sensor may capture one or more image frames of the image Imaging processing of the one or more image frames can be used to identify at least one scattering center corresponding to at least one particle of the one or more particles.

Abstract: A software code testing system includes sub-engines and a test case database storing test cases. A test case sub-engine runs each of the test cases on a plurality of software code modules, and a software code coverage determination sub-engine identifies a respective software code coverage for each software code method included in each of the software code modules. A test case/software code coverage mapping sub-engine then maps the respective software code coverage for each of the software code methods included in each of the software code modules with the respective test case that was run on that software code module to provide a test case/software code coverage mapping, which is used by a test suite optimization sub-engine to generate a test suite that includes a subset of the test cases that provide a desired level of software code coverage using a minimum number of test cases.

Abstract: A method and a current operational module for on-line measurement of battery internal resistance and an on-line measurement instrument for battery internal resistance have high measurement accuracy and strong anti-interference ability. The on-line measurement instrument for battery internal resistance comprises a current work module, a voltage measurement module, an analog to digital conversion module, a signal generation module, a center processing module, an Input/Output module, and a power supply module used for on-line measurement of battery internal resistance.
