    • The 2nu-SVM: A Cost-Sensitive Extension of the nu-SVM 

      Davenport, Mark A. (2005-12-01)
      Standard classification algorithms aim to minimize the probability of making an incorrect classification. In many important applications, however, some kinds of errors are more important than others. In this report we ...

    • 3D bioprinting: improving in vitro models of metastasis with heterogeneous tumor microenvironments 

      Albritton, Jacob L.; Miller, Jordan S. (2017)
      Even with many advances in treatment over the past decades, cancer still remains a leading cause of death worldwide. Despite the recognized relationship between metastasis and increased mortality rate, surprisingly little ...
    • 3D Geometry Coding using Mixture Models and the Estimation Quantization Algorithm 

      Lavu, Sridhar (2002-09-01)
      3D surfaces are used in applications such as animations, 3D object modeling and visualization. The geometries of such surfaces are often approximated using polygonal meshes. This thesis aims to compress 3D geometry meshes ...

      Suzuki reaction for covalently interconnected 3D carbon nanotube (CNT) architectures is reported. The synthesis of 3D macroscopic solids made of CNTs covalently connected via Suzuki cross-coupling, a well-known carbon-carbon ...
    • 3D microfabrication of single-wall carbon nanotube/polymer composites by two-photon polymerization lithography 

      Ushiba, Shota; Shoji, Satoru; Masui, Kyoko; Kuray, Preeya; Kono, Junichiro; Kawata, Satoshi (2013)
      We present a method to develop single-wall carbon nanotube (SWCNT)/polymer composites into arbitrary three-dimensional micro/nano structures. Our approach, based on two-photon polymerization lithography, allows one to ...
