Camera calibration with distortion models and accuracy evaluation

A camera model that accounts for major sources of camera distortion, namely, radial, decentering, and thin prism distortions is presented. The proposed calibration procedure consists of two steps: (1) the calibration parameters are estimated using a closed-form solution based on a distribution-free camera model; and (2) the parameters estimated in the first step are improved iteratively through a nonlinear optimization, taking into account camera distortions. According to minimum variance estimation, the objective function to be minimized is the mean-square discrepancy between the observed image points and their inferred image projections computed with the estimated calibration parameters. The authors introduce a type of measure that can be used to directly evaluate the performance of calibration and compare calibrations among different systems. The validity and performance of the calibration procedure are tested with both synthetic data and real images taken by tele- and wide-angle lenses

基于信息密级标识的多级域防护系统

如何有效控制不矧安全域之间的信息流向以及信息的访问控制是分级保护的一个工作重点。该系统利用Windows内核的驱动框架,通过嵌入在I／O管理器和文件系统驱动模块之间的文件过滤驱动模块向信息头部写入密级标,并结合管理中心分发的密钥,实现信息的动态透明加／解密,使涉密文件只能被有相应权限的用户所访问;信息控制引擎结合访问控制策略,实现信息流向控制,杜绝高密级信息向低密级域流动。     

Kuosheng BWR/6 stability analysis with LAPUR5 code

Unstable power/flow oscillation of a nuclear power reactor core is one of the main reasons that cause minor core damage. Stability analysis to determine system’s decay ratio needs to be performed at each core reload design to prevent core instability events from happening. Making use of LAPUR5 and SIMULATE-3 codes, we have established a methodology to conduct such analysis. Comparisons made with vendor’s STAIF results indicated close agreements, within acceptable ±0.2 in decay ratios, for Kuosheng NPP Unit2 Cycle 17 reloads design. Sensitivity studies have shown that density reactivity coefficient, delayed-neutron fractions (β) and decay constants (λ), total core flow, and core power axial shape are the most important parameters that might affect the accuracy of decay ratios. We have also found that core conditions at EOC result in larger decay ratios than those at BOC.

Cu在高磁感取向硅钢中的作用

本文采用透射电镜手段研究了Ｃｕ在高磁感取向硅钢Ｈｉ－Ｂ中的作用。结果发现，加Ｃｕ Ｈｉ－Ｂ钢在热轧过程中形成大量（Ｃｕ，Ｍｎ）１．８Ｓ和（Ｍｎ，Ｃｕ）Ｓ质点，前者较后者更加细小。随着硫化物质点尺寸的减小，质点中Ｃｕ相对于Ｍｎ的比例不断提高。由此证明，加Ｃｕ起到了提高硫化物析出量，减小硫化物质点尺寸的作用。同时发现，热轧时形成的硫化物质点经１１２０℃高温常化后发生了明显粗化。另外，在常化及脱碳板中，     

Inactivation of brainstem motor nuclei blocks expression but not acquisition of the rabbit's classically conditioned eyeblink response.

Rabbits were eyeblink conditioned while their accessory abducens nucleus (ACC), facial nucleus ( FN), and surrounding reticular formation (RF) were temporarily inactivated with microinjections of muscimol to determine whether these structures are critically involved in acquisition of the conditioned eyeblink response (CR). Rabbits performed no CRs or unconditioned responses (URs) during inactivation training. Training was continued without inactivation and rabbits performed the CR at asymptotic levels from the start of training without inactivation. They had fully learned the CR while their ACC, FN, and RF were inactivated, despite performing no CRs or URs at all during inactivation. These results rule out any critical role for neurons within the ACC, FN, or surrounding RF in acquisition of the classically conditioned eyeblink response.
