文摘A novel representation is developed as a measure for multilinear fractional embedding. Corresponding extensions are given for the Bourgain-Brezis-Mironescu theorem and Pitt＇s inequal- ity.

文摘The uncertainty principle proposed by German physicist Heisenberg in 1927 is a basic principle of quantum mechanics and signal processing.Since linear canonical transformation has been widely used in various fields of signal processing recently and Heisenberg uncertainty principle has been endowed with new expressive meaning in linear canonical transforms domain,in this manuscript,an improved Heisenberg uncertainty principle is obtained in linear canonical trans-forms domain.
文摘城市土地供应与投放攸关城市规划的有效实施,城市管理制度创新亟待新型的、多样化的土地估价技术方法的支持和应用。本文基于澳大利亚悉尼市Pitt Town的"Vermont"居住开发项目的土地出让数据,从土地物理属性的微观层面出发,尝试通过建立多元线性回归模型(Multiple Linear Regression Model,MLRM)来进行区域土地估价,为未来项目周边地区的开发提供决策参考。目前国内土地估价仍多以定性比较评估为主,本文深入探讨了MLRM方法在地价评估与预测中的应用,以期为国内相关领域提供借鉴和参考。
