不同粘弹性驱替液下毛管数对驱油效果的影响

通过在微亲水人造岩心上开展的室内驱油物理模拟试验,探讨了毛管数对不同粘弹性聚合物溶液驱油效率及残余油饱和度的影响.同时,在相同毛管数条件下,研究了不同粘弹性聚合物溶液对其驱油效率及残余油饱和度的影响,得到了不同粘弹性条件下毛管数与驱油效率关系的一族曲线;比较系统地研究了不同粘弹性聚合物溶液下毛管数对驱油效率及残余油饱和度的影响规律,即在毛管数相同的条件下,聚合物溶液的粘弹性越高,体系的采收率越高,残余油饱和度越低,说明了聚合物溶液的弹性也是影响其提高采收率、降低残余油饱和度的重要因素.对进一步深入研究聚合物驱油机理和现场作业具有行重要指导意义.

Model-based automated extraction of microtubules from electron tomography volume.

We propose a model-based automated approach to extracting microtubules from noisy electron tomography volume. Our approach consists of volume enhancement, microtubule localization, and boundary segmentation to exploit the unique geometric and photometric properties of microtubules. The enhancement starts with an anisotropic invariant wavelet transform to enhance the microtubules globally, followed by a three-dimensional (3-D) tube-enhancing filter based on Weingarten matrix to further accentuate the tubular structures locally. The enhancement ends with a modified coherence-enhancing diffusion to complete the interruptions along the microtubules. The microtubules are then localized with a centerline extraction algorithm adapted for tubular objects. To perform segmentation, we novelly modify and extend active shape model method. We first use 3-D local surface enhancement to characterize the microtubule boundary and improve shape searching by relating the boundary strength with the weight matrix of the searching error. We then integrate the active shape model with Kalman filtering to utilize the longitudinal smoothness along the microtubules. The segmentation improved in this way is robust against missing boundaries and outliers that are often present in the tomography volume. Experimental results demonstrate that our automated method produces results close to those by manual process and uses only a fraction of the time of the latter.     

Modular and rapid testing of SOCs with unwrapped logic blocks

Extensive research has been carried out for test planning of core-based system-on-a-chip devices. Most of the prior work assumes that all of the embedded cores are wrapped for test purpose. However, some designs may contain user-defined logic or cores that cannot be wrapped due to area constraints or timing violations. This paper discusses how these unwrapped logic blocks can be tested rapidly by adapting the TestRail architecture, which uses only the test control mechanism and the test instructions available through the IEEE 1500 standard for embedded core test. A new test scheduling algorithm, which facilitates a concurrent test of both unwrapped logic blocks and IEEE 1500-wrapped cores, is proposed, and experiments show that it outperforms a previous approach when the available number of tester channels and/or the number of unwrapped logic blocks are small.
