In an electromagnetic cloak based on a transformation approach, reduced sets of material properties are generally favored due to their easier implementation in reality, although a seemingly inevitable drawback of undesired reflection exists in such cloaks. Here we suggest using high-order transformations to create smooth moduli at the outer boundary of the cloak, therefore completely eliminating the detrimental scattering within the limit of geometric optics. We apply this scheme to a non-magnetic cylindrical cloak and demonstrate that the scattered field is reduced substantially in a cloak with optimal quadratic transformation as compared to its linear counterpart.

C語言的開發模式, 是編寫.c的Source Code, 再經由Compiler編譯成Object Code。所謂Object Code指的是和硬體相關的機器指令, 也就是說當我們想要把C程式移植到不同的硬體時, 必須要重新Compile,以產生新的執行檔。除了需要重新編譯外,新系統是否具備應用程式所需的程式庫,include的檔案是否相容, 也是程式能否在新機器上順利編譯和執行的條件之一。

In computer vision, sets of data acquired by sampling the same scene or object at different times, or from different perspectives, will be in different coordinate systems. Image registration is the process of transforming the different sets of data into one coordinate system. Registration is necessary in order to be able to compare or integrate the data obtained from different measurements. Image registration is the process of transforming the different sets of data into one coordinate system. To be precise it involves finding transformations that relate spatial information conveyed in one image to that in another or in physical space. Image registration is performed on a series of at least two images, where one of these images is the reference image to which all the others will be registered. The other images are referred to as target images.

Although some FX1-based devices may use the FX1鈥檚 CPU to process USB data directly (Port I/O Mode), most applica- tions use the FX1 simply as a conduit between the USB and external data-processing logic (e.g., an ASIC or DSP, or the IDE controller on a hard disk drive).
