This paper investigates the combined effect of kiln or brick surface roughness and lattice setting density on fluid flow heat transfer characteristics in tunnel kilns. The uniformity, pressure drop, convective coefficient (CHTC), pumping power are studied. A high-density (HDS), which comprises 768 bricks, a low-density (LDS), 512 tested for boundaries levels 0, 1, 2, 3, 4 mm. investigation is c...

The quality of OpenStreetMap (OSM) data has always been of main concern for use in different projects. In our study, in order to understand the fitness for use of OSM data for a routing and navigation system for people with limited mobility, we have assessed the completeness of OSM data with regards to sidewalk information. Relevant attributes for sidewalk information have been considered, and ...

China’s highway construction has moved from “construction-oriented” to the development stage of “equal attention and maintenance”. The infrastructure represented by urban expressways, under heavy complex traffic loads, is prone a variety diseases that take place in middle lower layers pavement such as “frost boils” “voids”, which cannot be repaired ideally with help conventional detection treat...

Criticism is not merely a good thing; the discipline requires it to advance. Precisely because it is so important, criticism must be held to high scholarly standards. As I will show, Wacquant’s review of Sidewalk quotes selectively and misleadingly and systematically misrepresents the work as a whole. The review is thoroughly inaccurate and unreliable. Forty years after Jane Jacobs wrote The De...

Tailored routing and navigation services utilized by wheelchair users require certain information about sidewalk geometries and their attributes to execute efficiently. Except some minor regions/cities, such detailed information is not present in current versions of crowdsourced mapping databases including OpenStreetMap. CAP4Access European project aimed to use (and enrich) OpenStreetMap for ma...

Recent work has indicated that prior research is insufficient to support the ADA Accessibility Guidelines' (ADAAG) 2% maximum cross-slope requirement for sidewalks. In addition, the present ADAAG are inflexible in that they do not consider deviations from this maximum for short sections of sidewalk, such as at driveway crossings, which can be of significant concern for state and local departmen...

In this paper, we propose a new bricked cache system suitable for a particular surface propagation algorithm : seismic horizon reconstruction. The application domain of this algorithm is the interpretation of seismic volumes used, for instance, by petroleum companies for oil prospecting. To ensure the optimality of such surface extraction, the algorithm must access randomly into the data volume...

This paper presents a novel interface element for the geometric and material nonlinear analysis of unreinforced brick-masonry structures. In the proposed modelling approach, the blocks are modelled using 3D continuum solid elements, while the mortar and brick-mortar interfaces are modelled by means of the 2D nonlinear interface element. This enables the representation of any 3D arrangement for ...

This is the first study of adobe brick contamination anywhere in the world. Huancavelica, Peru is the site of historic cinnabar refining and one of the most mercury (Hg) contaminated urban areas in the world. Over 80% of homes in Huancavelica are constructed with adobe bricks made from Hg contaminated soil. In this study we measured total Hg concentrations in adobe brick, dirt floor, surface du...
