In the European Union, built environment is responsible for more than 25% of all waste generated, highlighting need to adopt circular practices. To indicate level circularity, common indicators mainly focus on: 1) amount virgin materials, 2) unrecoverable waste, and 3) product lifetime. However, a holistic methodology covering macro (material impact), meso (supply chain) micro (design) still be...

We propose a new technique for designing decision feedback detectors (DFDs) wherein the per-symbol decision rules are obtained by exploiting modulation constraints. We present our results in the context of the multi-input, multioutput (MIMO) Rayleigh fading channel with N receive and K transmit antennas. Three cases are considered to illustrate our technique where all the transmitters employ re...

Conventional construction materials which rely on a fossil-based, nonrenewable extractive economy are typically associated with an entrenched linear economic approach to production. Current research indicates the clear interrelationships between production and use of anthropogenic climate change. This paper investigates potential for emerging high-performance biobased materials, produced sustai...

BACKGROUND Long-gap peripheral nerve defects arising from tumor, trauma, or birth-related injuries requiring nerve reconstruction are currently treated using nerve autografts and nerve allografts. Autografts are associated with limited supply and donor-site morbidity. Allografts require administration of transient immunosuppressants, which has substantial associated risks. To overcome these lim...

Real-time and accurate autofocusing of stationary and moving objects is an important problem in modern digital cameras. Depth From Defocus (DFD) is a technique for autofocusing that needs only two or three images recorded with different camera parameters. In practice, there exist many factors that affect the performance of DFD algorithms, such as nonlinear sensor response, lens vignetting, and ...
