In this paper, we discuss the applicat[ons ant! implications of the Programmable Brick-s-s tiny, portable computer embecfded ~nside a LE~Q'J brick, capable of interacting with the phys!cal world in a large variety of ways. We describe how Programmable Bricks make possible a wide range of new design activities for children, and we discuss experiences in using Programmable Bricks in three types o...

During a medical entomology course in Boa Vista, Roraima, colonies of Triatoma maculata closely associated with pigeon nests were observed in concrete air-conditioner box located on the external plastered and cemented walls of a modern brick-built apartment block. In only one eight-hole ceramic brick, located inside one air-conditioner box, 127 specimens of T. maculata were collected. T. macula...

As in the case of two-dimensional topology design optimization, numerical instability problems similar to the formation of two-dimensional checkerboard patterns occur if the standard eight-node conforming brick element is used. Motivated by the recent success of the two-dimensional non-conforming elements in completely eliminating checkerboard patterns, we aim at investigating the performance o...

Balancing business strategy and operations between electronic commerce and brick and mortar channels (‘clicks and mortar’) is an ongoing challenge for many businesses. A group of traditional ‘brick and mortar’ firms were examined in order to understand how they balance strategy and operations between electronic commerce and traditional (brick and mortar) business channels. Results of the study ...

Dissections of polytopes are a well-studied subject by geometers as well as recreational mathematicians. A recent application in coding theory arises from the problem of parameterizing binary vectors of constant Hamming weight [TVS09], [SV09], which is shown to be equivalent to the problem of dissecting a tetrahedron to a brick. An application of dissections to a problem related to the construc...

The Multi-Chip-Module-Deposited (MCM-D) technique has been used to build hybrid pixel detector assemblies. This paper summarises the results of an analysis of data obtained in a test beam campaign at CERN. Here, single chip hybrids made of ATLAS pixel prototype read–out electronics and special sensor tiles were used. They were prepared by the Fraunhofer Institut für Zuverlässigkeit und Mikroint...

Since the work of George Richardson on the problem of investment co-ordination, the literature has focused on explaining equilibrium in investment games and neglected the problem of how investments are co-ordinated. This paper reports the findings of a case study of the brick industry which used grounded theory techniques to develop a new analysis of investment coordination. Our main findings i...

The calculation of electromagnetic (EM) fields and waves inside finite-sized structures comprised of different media can benefit from a diakoptics method such as linear embedding via Green’s operators (LEGO). Unlike scattering problems, the excitation of EM waves within the bulk dielectric requires introducing sources inside the structure itself. To handle such occurrence, we have expanded the ...

We address a question posed by T. Sibley and Stan Wagon. They proved that rhombic Penrose tilings in the plane can be 3-colored, but a key lemma of their proof fails in the natural 3D generalization. In that generalization, an object is built from bricks, each of which is a parellelopiped, and they are glued face-toface. The question is: How many colors are needed to color the bricks of any suc...
