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...

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...

The swell-shrink behavior of expansive clay soil cause problems in the construction such as occurrence bumpy road, cracking and various other problems, therefore stabilization is needed to improve soil.Red brick a building material that contains chemical compounds can increase compressive strength building. Red waste which rarely used then reused cement mixture.This study aims determine type cl...

Engineers and architects are using engineering simulations to design buildings to attain energy efficiency, sustainable goals and utilize renewable resources. Fluid dynamics simulations have proven to be a powerful and effective tool providing flexible solutions. These simulations are used as an optimization and validation tool at an early phase in the design process. Building, as one of the la...

During the MoDeCo2000 scientific and research project on mortars used in territory of Roman Danube Limes Serbia, biggest challenge was quest for provenance raw materials. The area where Viminacium, largest city province Moesia Superior developed, with millennial continuity land use settlement, selected as case study is presented this research. People throughout history have always what they had...
