Building a Nest by an Automaton [PDF]

open access: yes, 2019
A robot modeled as a deterministic finite automaton has to build a structure from material available to it. The robot navigates in the infinite oriented grid Z x Z. Some cells of the grid are full (contain a brick) and others are empty.

New materials for fireplace logs [PDF]

open access: yes, 1971
Fibrous insulation and refractory concrete are used for logs as well as fireproof walls, incinerator bricks, planters, and roof shingles. Insulation is lighter and more shock resistant than fireclay.

A Structure result for bricks in Heisenberg groups

open access: yes, 2013
We show that for a sufficiently big \textit{brick} $B$ of the $(2n+1)$-dimensional Heisenberg group $H_n$ over the finite field $\mathbb{F}_p$, the product set $B\cdot B$ contains at least $|B|/p$ many cosets of some non trivial subgroup of $H_n$

Optimalisasi Jumlah Batu Bata Yang Pecah Menggunakan Desain Eksperimen Taguchi (Studi Kasus: USAha Batu Bata Bapak Kholil Ds. Bulak Karangawen) [PDF]

open access: yes, 2014
Brick is a substansial element in building construction. The strength of building may depend on bricks, a solid construction uses the best quality brick's, which is not crumbling and broken into two parts.

Sais solúveis e eflorescência em blocos cerâmicos e outros materiais de construção - revisão Soluble salts and efflorescence of ceramic bricks and other building materials - review

open access: yesCerâmica, 2006
Eflorescências são depósitos salinos que se formam na superfície de materiais cerâmicos, resultantes da migração e posterior evaporação de soluções aquosas salinizadas.

Physicochemical, Mineralogical and Microscopic Evaluation of Sustainable Bricks Manufactured with Construction Wastes

open access: yesApplied Sciences, 2017
At an international level, enormous volumes of construction and demolition wastes are generated: 170 million tons/year in the USA, 500 million tons/year in the European Union (EU) and 12 million tons/year in Mexico.

Pairwise Compatibility for 2-Simple Minded Collections

open access: yes, 2020
In $\tau$-tilting theory, it is often difficult to determine when a set of bricks forms a 2-simple minded collection. The aim of this paper is to determine when a set of bricks is contained in a 2-simple minded collection for a $\tau$-tilting finite ...

Using Waste in Producing Bio-Composite Mycelium Bricks

open access: yesApplied Sciences, 2020
One of the major causes of an increase in the consumption of resources is the progress of the construction industry. Although it leads to new technologies, it heavily contributes to global warming.

Search for spontaneous muon emission from lead nuclei

open access: yes, 2005
We describe a possible search for muonic radioactivity from lead nuclei using the base elements ("bricks" composed by lead and nuclear emulsion sheets) of the long-baseline OPERA neutrino experiment.
