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.

Fortran 90 versions of all the Numerical Recipes routines appear in the following Chapters B1 through B20, numbered in correspondence with Chapters 1 through 20 in Volume 1. Within each chapter, the routines appear in the same order as in Volume 1, but not broken out separately by section number within Volume 1鈥檚 chapters. There are commentaries accompanying many of the routines, generally following the printed listing of the routine to which they apply. These are of two kinds: issues related to parallelizing the algorithm in question, and issues related to the Fortran 90 implementation. To distinguish between these two, rather different, kind

The paper describes the concept and realization of the DOOCS control software for FPGAbased TESLA cavity controller and simulator (SIMCON). It bases on universal software components, created for laboratory purposes and used in MATLAB based control environment. These modules have been recently adapted to the DOOCS environment to ensure a unified software to hardware communication model. The presented solution can be also used as a general platform for control algorithms development. The proposed interfaces between MATLAB and DOOCS modules allow to check the developed algorithm in the operation environment before implementation in the FPGA. As the examples two systems have been presented.

摘 要 文章以空間監控系統為背景,深入研究了JPEG圖像壓縮標準的實現方法,并基于FPGA對其進行了實現和優化。文中給出了詳細的實現方法和優化過程,測試表明達到了很好的效果。 簡單介紹了有損靜態圖像壓縮當前有兩種比較流行的標準JPEG和JPEG2000。說明了用JPEG方法壓縮的原因。 介紹JPEG基本原理：JPEG對灰度圖像的壓縮處理過程主要包括:圖像分割,離散余弦變換(DCT),量化(Quantization),“Z”形排序(Zigzag Scan),差分脈沖編碼調制(Differential Pulse Code Modulation,DPCM)對直流系數(DC),行程長度編碼(Run-Length Encoding,RLE)對交流系數(AC),霍夫曼(Huffman)編碼等。 JPEG標準的特點是離散余弦變換。 比較詳細介紹壓縮系統的構成和實現。實現提及步驟， JPEG壓縮模塊設計和編碼模塊實現細節。
