A thin layer of ductile fiber-reinforced mortar material referred to as Engineered Cementitious Composites, or ECC has been experimentally investigated as a seismic retrofit for unreinforced masonry infill walls in non-ductile reinforced concrete frames. Compression tests of masonry prisms retrofitted with 13mm of ECC were conducted representing the compression strut of a masonry infill under i...

Prefabricated engineered solid wood panel construction systems can sequester and store CO2. Modular cross-laminated timber (CLT, also called cross-lam) panels form the basis of low-carbon, engineered construction systems using solid wood panels that can be used to build residential infill developments of 10 storeys or higher. Multi-apartment buildings of 4 to 10 storeys constructed entirely in ...

This paper presents a new perspective of the impact of information and collaboration technology (IT) on the work place and space. The study is at the intersection of the and new ways people behave in communicative events using the affordances of IT augmented spaces and content, i.e., interaction. The study proposes two hypotheses. Brick & Bits & Interaction Hypothesis: If we understanding the t...

A multi proxy approach was applied in the reconstruction of the architecture of Medieval horse stable architecture, the maintenance practices associated with that structure as well as horse alimentation at the beginning of 13th century in Central Europe. Finally, an interpretation of the local vegetation structure along Morava River, Czech Republic is presented. The investigated stable experien...

Apopular approach to handling constraints in surrogate-based optimization is through the additionof penalty functions to an infill sampling criterion that seeks objective improvement. Typical samplingmetrics, such as expected improvement tend to have multimodal landscapes and can be difficult to search. When the problem is transformed using a penalty approach the search can become riddled with ...

A test chamber was projected and built (according to ISO 16000-9 Standard) to simulate atmospheric conditions experienced by rubber infill (when applied in synthetic turf pitches) and measure accurately the airborne emissions of pollutants such as dusts and volatile organic compounds (VOC), as well as pollutants present in leachates. It should be pointed out that standard ISO 16000-9 is only co...

The use of surrogate models or metamodeling has lead to new areas of research in simulation-based design optimization. Metamodeling approaches have advantages over traditional techniques when dealing with the noisy responses and=or high computational cost characteristic of many computer simulations. This paper focuses on a particular algorithm, Efficient Global Optimization (EGO) that uses krig...

Partially Lateritised Khondalite (PLK) rocks are the waste materials generated as a result of mining of bauxite. The major discolouring elemental impurity in the PLK is iron oxides, which render it unsuitable for its use as a refractory material. The iron can be removed by suitable beneficiation methods. The main aim of this present investigation is to prepare a value added material from the mi...

Self-assembly provides an information-economical route to the fabrication of objects at virtually all scales. However, there is no known algorithm to program self-assembly in macro-scale, solid, complex 3D objects. Here such an algorithm is described, which is inspired by the molecular assembly of DNA, and based on bricks designed by tetrahedral meshing of arbitrary objects. Assembly rules are ...

ABSTRACT: Many traditional brick-and-mortar businesses supplement their physical outlets with e-commerce capabilities on the Web, but there has been lit tle empirical research on the underlying dynamics of the “click-and-mortar” business approach. This paper develops a conceptual framework that highlights the four types of synergies obtained by integrating e-commerce with physical infrastructur...
