Building, block, street : residential block design
… imposed by traditional street pattern and block size, is fundamentally anti-urban. Modern American housing of the post-World War II era, like any complex social phenomenon, was influenced by multiple forces. Among the most salient are single proprietary control of large parcels of urban …

Inter-block analysis of incomplete block designs
… of balanced and partially balanced incomplete block designs, certain ones have been found which lend themselves nicely to interblock analysis. Besides facilitating this analysis, these designs make possible the use of a new method for studying the relative variability of the inter and …

Collective urban block
… how the master plan has replaced urban block as a spatial tool for the making of the city. The result of this practice is Le Corbusier's radiant city in a dystopian state: parallel blocks of residential towers enclosed in gated communities that are detached from the city. Currently, …

Combined intra- and inter-block analysis for factorials in incomplete block designs
… Bradley on the use of factorials in incomplete block designs bas been extended to permit both the intra-block and combined intra- and inter-block analyses of factorials in balanced and partially balanced incomplete block designs. In particular, we have obtained a combined intra- and inter-block …

Multi-Way Block Models
This dissertation investigates the Multi-Way Block Models proposed for mining inner structure of interaction between two sets of subjects. The Multi-Way Block Models generalize the Mixed Membership Stochastic Block Models (Airoldi et al., 2008) in multi-ways, as extensions in model settings …

Block copolymer photonic crystals
This thesis explores the photonic properties of block copolymer systems. One dimensionally periodic dielectric stacks are fabricated with symmetric, lamellar forming, copolymer systems: diblock copolymers, solvent swollen BCP materials, and homopolymer swollen BCP blends. Each system exhibits …

Rheological and Mechanical behaviour of Block copolymers, Multigraft copolymers and Block copolymer Nanocomposites
Block copolymers are commercially significant and fundamentally interesting class of polymeric materials. The ability to undergo interfacial thermodynamics-controlled microphase separation from a completely disordered state in the melt to a specifically defined ordered structure through …

Deformation behavior of cylindrical block copolymer bicrystals : pathway to understanding block copolymer grain boundaries
… styrene-isoprene-styrene (SIS) cylindrical block copolymer (BCP), produced by a roll-casting process; yield various types of pure tilt grain boundaries. The study of the deformation of the bicrystals, each containing one grain boundary, enables a deeper understanding of the influences grain …

Source-controlled block turbo coding
This thesis proposes the use of block turbo codes for transmitting nonuniform binary memoryless sources over AWGN channels. As opposed to standard convolutional turbo codes, block turbo codes are known to achieve good performance for high code rates, up to 98% of the channel capacity for uniform …

Haplotype block and genetic association
… (Daly et al. 2001 and Patil et al. 2001) block-like structure in the human genome has attracted much attention since each haplotype block contains limited sequence variation, which can reduce the complexity in genetic mapping studies. This dissertation focuses on estimating haplotype block …

GPU implementation of block transforms
Traditionally, intensive floating-point computational ability of Graphics Processing Units (GPUs) has been mainly limited for rendering and visualization application by architecture and programming model. However, with increasing programmability and architecture progress, GPUs inherent massively …

Finite geometries and block designs
… affine and projective planes as well as block designs. We conclude with a chapter on how to apply these ideas to coding theory. Some of the results we look at include both the Bruck-Ryser and Bruck-Ryser-Chowla theorems as well as considering isomorphisms and automorphisms of block …

Ceramic nanostructures for block copolymers
… media) become smaller and smaller. In this work, block copolymers are harnessed in order to produce both porous and relief nanostructures. The interest in using these materials is due to the unique morphologies that block copolymers form and the fact that these nanostructures do so by self …

Liquid crystalline multi-block copolymers
Lyotropic and thermotropic high strength liquid crystalline polymers have become an important area of research and development in polymeric, high performance materials. These materials have afforded excellent high temperature stability and high strength in the oriented direction, but not in the …
