Abstract Cities worldwide are facing a number of serious challenges including population growth, resource depletion, climate change, and degradation ecosystems. To cope with these challenges, the transformation our cities into sustainable systems using holistic approach is required. The pathway to this urban transition adopting concept circular economy for management. In way, resources kept reu...

To accelerate Circular Economy (CE) implementation in the built environment, integrated information systems that are capable to identify, coordinate, and evaluate CE collaborations across heterogeneous projects demand. A digital collaborative hub, Circularity Information Platform (CIP), is a promising solution streamline complex exchanges foster symbiotic material interactions broader circular ...

Request (BWR) is the mechanism by which the Subscriber Station (SS) communicates its need for uplink bandwidth allocation to the Base Station (BS). The performance of the system is affected by the collisions of BWR packets in uplink transmission, that have the direct impact on the size of the contention period in uplink sub frame, uplink access delay and uplink throughput. In this paper, we eva...

Mineral Aerosol dusts have complex non spherical shapes and varying composition. This is utilizes data on morphology (size and shape) and composition of dust particles to determine the extent to which the optical properties of real particles differ from those of spheres. In morphology we find the aspect ratio, circularity factor and radius than discuss the size and shape of the aerosol dust par...

Representing shapes is a signiicant problem for vision systems that must recognize or classify objects. We derive a representation for a given shape by investigating its self-similarities, and constructing its shape axis(SA) and shape axis tree (SA-tree). We start with a shape, its boundary contour, and two diierent parameterizations for the contour. To measure its self-similarity we consider m...
