Hydrated cement paste has a high specific surface area due almost entirely to the calcium-silicate-hydrate reaction product. The surface area of cement paste is closely related to many crucial properties, including strength and permeability, and is therefore a useful predictive measurement. It is also a useful parameter for studying the nature of the calcium-silicate-hydrate gel itself. Unfortu...

Building on the theory of elliptic operators, we give a unified treatment of the following topics: • the problem of homotopy invariance of Novikov’s higher signatures on closed manifolds; • the problem of cut-and-paste invariance of Novikov’s higher signatures on closed manifolds; • the problem of defining higher signatures on manifolds with boundary and proving their homotopy invariance.

To simplify the selection of remote targets on large displays, a novel technique called ShifTable is presented in this paper. With ShifTable, users move a finger or a pen towards a desired target, and the whole screen carrying the target shifts faster in the opposite direction, towards the finger or pen. We conducted two experiments to compare ShifTable with unaided direct selection (baseline),...

This paper describes a method to detect segments within a piece of music. These segments are the characters and words that make up music, and they are found by analyzing the self-similarity of a waveform. The segments can be on any level, so this method is a reliable way of extracting notes or phrases from a musical signal. Some potential applications for audio segmenting, such as smart cut-and...

In this paper, we describe a copy-and-paste method for constructing a class of infinite self-similar trees. A copy-paste tree is constructed by repeatedly attaching copies of a finite tree (called a generator) to certain designated attachment vertices. We show that each generator has an associated nonnegative matrix which can be used to determine a formula for the growth function of the copy-pa...
