Construction and demolition (C&D) materials are generated when new building and civil-engineering structures are built and when existing buildings and civil-engineering structures are renovated or demolished (including deconstruction activities). Civil-engineering structures include public works projects, such as streets and highways, bridges, utility plants, piers, and dams. C&D materials often …

Cities have become the new battleground and Hybrid or Urban Warfare the greatest threat being waged by ISIS to Boko Haram to Hamas to Ukraine rebels. Urban warfare is fundamentally unchanged since World War I in many regards: battle is human-centric, with most casualties resulting from discovering the enemy; a …
Read More »The military/defense industry continues to encourage the advancement of multifunctional receivers. Yet the demands for higher-frequency operation, increased bandwidth, increased dynamic range, and enhanced sensitivity creates unique design challenges for present technology. Size, weight, power, and cost (SWAP-C) dynamics heavily influence the military/defense industry’s value for a particular technology. …

Generally, materials will degrade over time due to fatigue, environmental conditions, or damage incurred during operation. Repair of certain materials during their lifecycle (especially those with structural functions such as concrete) can be very expensive and labour intensive. Therefore Scientists began developing self-healing materials , those artificial (synthetic) substances that …

Photonic crystals are periodic optical structures that can control the flow of light. Multiple reflections from surfaces separated by a distance similar to the wavelength prevent an optical beam from propagating through the crystal. Photonic crystal devices can therefore force light around sharp bands or even trap it entirely. …
