简介:介绍配对的Haar变换被显示出的最近的不同性质。不完全地指定的布尔功能的NonpolynomialHaarPxpansion被介绍了。把配对的Haar光谱的一些应用基于上述性质和扩大被建议了。为Haar对光谱从的计算的算法拆散为不完全地指定的布尔功能的系统的立方体也被开发了。

简介:客观:等待的病人预定设计一个软件在平淡的内部放射性核种照耀治疗自动地做复杂、多重的计算避免错误并且弄短。方法:软件在MicrosoftWindowsXP操作系统上被设计。可视化Basic5.0和微软存取2000分别地被用作这里的程序语言和数据库系统。数据和DBGrid控制和可视化Basic的VB数据窗户指南习惯于的控制存取和存取数据库。结果:任何放射性核种的放射性能不仅是计算的,而且为甲状腺机能亢进或甲状腺癌症和总数的治疗的管理的全部的碘剂量为恶意的肿瘤的骨头转移的补救管理153个Sm-EDTMP答案能在外面是ciphered。结论:当软件能自动地做复杂、多重的计算时,工作变得更容易、更快、更正确、有趣。病人的信息,诊断和治疗能为进一步的学习被记录。
