Sculpting China: critical puppetry and the formation of diasporic identity in 'Chang and Eng and Me (and Me)'
No full textIn my short, filmed puppetry performance Chang and Eng and Me (and Me) (2021), the audience witness the construction, manipulation and destruction of figures representing the Siamese-Chinese conjoined twins Chang and Eng Bunker. These processes mirror the formations and transformations of identities that Chang and Eng underwent as diasporic individuals in Siam, on tour in Europe and as naturalised U.S. citizens. In this essay, I analyse these examples from my own practice to propose a framework for critical puppetry and to assert its value as an embodied form of inquiry and resistance

A modified HLLC-type Riemann solver for the compressible six-equation two-fluid model
No full textWe present a modified HLLC-type Riemann solver that is applicable to the compressible six-equation two-fluid model of the two-phase flow. The modified HLLC scheme restores all the characteristic fields that have been neglected by the recent HLLC scheme proposed by Zein et al. (Zein A, Hantke M, Warnecke G. Modeling phase transition for compressible two-phase flows applied to metastable liquids. J Comput Phys 2010;229:2964-98). We test the modified HLLC scheme on several 1D two-phase shock tube problems and a 2D shock-bubble interaction problem. The modified HLLC scheme is proved more accurate than other schemes like the Zein et al.'s HLLC scheme and the earlier two-phase HLL scheme developed by the present authors (Yearn GS, Chang KS. Numerical simulation of two-fluid two-phase flows by HLL scheme using an approximate Jacobian matrix. Numer Heat Transfer B-Fund 2006;49:155-77). The numerical test indicates that the present HLLC scheme is very robust and effective in acquiring high resolution for the waves in the six-equation two-fluid model. (C) 2013 Elsevier Ltd.

Motion-compensated reconstruction based on filtered backprojection for helical head CT
No full textIn head CT imaging, it is assumed that the patient’s head does not move during the CT acquisition. In clinical practice, however, the head sometimes moves and thereby causes considerable motion artifacts on the reconstructed image. To solve this motion artifact problem, motion estimation (ME) and motion-compensated (MC) reconstruction are needed. Reliable MC reconstruction is especially critical, because it is usually used for ME in addition to motion compensation. In this work, we propose a novel MC reconstruction algorithm for helical head CT, under the assumption that the head motion is rigid. CT acquisition of a rigidly moving object in a helical scan geometry can be considered as the acquisition of a static object in the scan geometry virtually transformed according to the motion. Based on this consideration, we propose a MC reconstruction algorithm by assuming that the head motion is already estimated. The algorithm consists of three consecutive steps, namely, MC rebinning, tangential filtering, and weighted backprojection. In the rebinning step, a virtually transformed helical geometry according to the motion is carefully taken account of, and a new weighting function is introduced to the backprojection step to minimize unwanted artifacts. To evaluate the proposed algorithm, we perform simulations by using a numerical phantom with pre-defined motion in a helical scan geometry. The proposed MC algorithm well restores a reconstructed image that is corrupted by motion, and thereby achieves the image quality comparable to that of the phantom with no motion
