In order to make renewable energy technology deployment strategies politically acceptable, many countries are linking them to other socio-economic goals. A controversial industrial policy tool that is increasingly popular is the use of local content

Billions of people use traditional renewable energy (wood, charcoal and dung) to cook in and heat their homes. These traditional methods create serious health and environmental hazards, leading to renewed efforts to bring cleaner, more efficient stov

In 1902 Second Naval Lord Jackie Fisher and the Earl of Selborne, the First Lord of the Admiralty, announced a scheme which would fundamentally change the way cadets for the engineering, executive and Royal Marine branches were entered and trained. K

We discuss properties of the "beamsplitter addition" operation, which provides a non-standard scaled convolution of random variables supported on the non-negative integers. We give a simple expression for the action of beamsplitter addition using gen

Ultra-reliable Point-to-Multipoint (PtM) communications are expected to become pivotal in networks offering future dependable services for smart cities. In this regard, sparse Random Linear Network Coding (RLNC) techniques have been widely employed t

The “water-energy-food nexus” has become an increasingly popular way to frame the challenges associated with reconciling human development objectives with responsible management of natural resources and ecosystems. Yet the nexus is complex, requi

We describe five types of results concerning information and concentration of discrete random variables, and relationships between them, motivated by their counterparts in the continuous case. The results we consider are information theoretic approac

We consider nonadaptive group testing where each item is placed in a constant number of tests. The tests are chosen uniformly at random with replacement, so the testing matrix has (almost) constant column weights. We show that performance is improved
