We report a small advance on a question raised by Robertson, Schweitzer, andWagon in [RSW02]. They constructed a genus-13 polyhedron built from bricks without corners, and asked whether every genus-0 such polyhedron must have a corner. A brick is a parallelopiped, and a corner is a brick of degree three or less in the brick graph. We describe a genus-3 polyhedron built from bricks with no corne...

A (semi)brick over an algebra is a module S such that its endomorphism ring EndA(S) (product of) division algebra. For each Dynkin diagram Δ, there bijection from the Coxeter group W of type Δ to set semibricks preprojective Π which restricted join-irreducible elements bricks Π. This paper devoted giving explicit description these bijections in case Δ=An or Dn. First, for element w∈W, we descri...

An Euler brick is a cuboid with integer side dimensions such that the face diagonals are integers. Already in 1740, families of Euler bricks have been found. Euler himself constructed more families. If the space diagonal of an Euler brick is an integer too, an Euler brick is called a perfect Euler brick. Nobody has found one. There might be none. Nevertheless, it is an entertaining sport to go ...

The work presents a practical investigation on the degree of efflorescence on different types of bricks available in Bangladesh. A relationship between the type of brick and degree of efflorescence is observed. The study is performed on five different types of samples. For this purpose the general procedure for a brick production is followed by making two samples of customized brick from two di...

We describe an improvisational companion based on the concept of harmonic bricks, as articulated by Cork and others. Our companion is software that can play background for, and trade melodies with, a human soloist. While exhibiting creativity itself, its greater purpose is to improve creativity of its user. Bricks, originally intended for memorization of chord progressions, are used here as a s...

Objective: To determine whether egocentric distance judgments are accurate in a virtual environment using a perceptual matching task. Methods: Observers were immersed within a virtual environment consisting of an L-shaped room with a test object (a column) located down one corridor and a comparison object (a flagpole) located down the other. Perceived distances were measured by having the obser...

If you have any questions, please contact: [email protected] [email protected] The Archaeological Sites Finds Identifier application is a tool for expert users and nonprofessionals to identify findings made all over Europe. In our prototype implementation, developed in course of the BRICKS project, the integrated findings are restricted to coins found in the Uni...

During narrative comprehension, readers construct representations of the situation described by a text, called situation models. Theories of situation model construction and event comprehension posit two distinct types of situation model updating: incremental updating of individual situational dimensions, and global updates in which an old model is abandoned and a new one created. No research t...

A performance-based seismic assessment of unreinforced masonry (URM) buildings requires the use of reliable models, able to predict their nonlinear force-displacement response including their displacement capacity. Among the possible methodologies, at different levels of complexity, macro-modelling using structural component elements has proved to be an approach that can provide satisfactory ac...
