    摘要： A rotor for a dynamoelectric machine includes a rotor core having an outer periphery and at least a first set of magnets positioned within the outer periphery of the rotor core. The first set of magnets includes at least two block magnets and an arc magnet. The block magnets have a substantially parallel magnetization pattern and the arc magnet has a substantially radial magnetization pattern. The arc magnet has a concave surface facing the outer periphery of the rotor core. The first set of magnets defines a pole of the rotor. Rotors with other magnet configurations, and dynamoelectric machines and compressors incorporating such rotors, are also disclosed.

    摘要： A scintillation-crystal based gamma-ray detector with photon sensors disposed on edge surface(s) of the crystal to take advantage of total internal reflection of scintillation photons within the thin-slab detector substrate to improve spatial resolution of determination of a scintillation event (including depth-of-interaction resolution) while preserving energy resolution and detection efficiency. The proposed structure benefits from the reduced—as compared with related art—total number of readout channels elimination of need in complicated and repetitive cutting and polishing operations to form pixelated crystal arrays used in conventional PET detector modules. Detectors systems utilizing stacks of such detectors, and methods of operation of same.

    摘要： A magnetic unlocking device and a magnetic unlocking structure of a magnetic encoding key. The magnetic unlocking structure includes a lock core device and a magnetic unlocking device. The lock core device includes a lock core casing, a lock knob which is provided in the internal cavity of the lock core casing, a lock care front end cover and a lock core rear end cover that are located at both ends of the lock core casing. The internal wall of the lock core casing is provided with a monad longitudinal moving groove and a monad horizontal rotating groove. The lock knob is provided with an unlocking hole. The external wall of the lock knob is provided with a monad longitudinal slide-way. The monad longitudinal slide-way and the monad longitudinal moving groove correspond to each other and form a monad moving cavity.

    摘要： An automated, self-adaptive framework prioritizes software testing in a consistent and effective manner. A metric evaluates past test execution information for assigning regression testing priority. The metric may be calculated with reference to one or more of the following factors taken in combination: requirement, coverage, history, and cost. The requirement factor considers customer-assigned priority of testing the code, complexity of implementing the code, and proneness of the code to faults. The coverage factor considers code coverage, feature coverage, and common usage rate. The history factor considers previous bug found rate, case stable rate, and priority to calculate. The cost factor considers test case execution time, and step length. A value of each factor for one test case is measured according to that test case and is not related to other test cases. The calculation result representing the metric for each test case determines a priority of the test case.

    摘要翻译： 自动化的自适应框架以一致和有效的方式优先考虑软件测试。 指标评估过去的测试执行信息，以分配回归测试优先级。 可以参考以下组合中的一个或多个因素来计算度量：要求，覆盖率，历史和成本。 要求因素考虑了客户分配的测试代码的优先级，实现代码的复杂性和代码的错误。 覆盖率考虑代码覆盖率，功能覆盖率和常用使用率。 历史因素考虑以前的错误发现率，病例稳定率和优先级来计算。 成本因素考虑测试用例执行时间和步长。 一个测试用例的每个因子的值根据该测试用例进行测量，与其他测试用例无关。 表示每个测试用例的度量的计算结果决定了测试用例的优先级。

    摘要： Disclosed are methods and systems for calculating a contrast reagent (CR) extravasation rate constant and generating a contrast reagent leakage corrected relative cerebral blood volume (rCBV) image map of a brain region from dynamic susceptibility contrast (DSC) magnetic resonance imaging (MRI) time-course image data based on pharmacokinetic first principles. In one example approach, a computerized method may include performing a linearization transform of a DSC MRI time-course equation which accounts for an intravascular contribution and an extravasating component, and calculating CR leakage from a slope of a linear portion of the transformed data.
