This paper presents analytical expressions for the mobility ( [[EQUATION]] ) and diffusion coefficient ( [[EQUATION]] ) of a chemical compound [[EQUATION]] that react with a carrier [[EQUATION]] giving a product [[EQUATION]] in the presence of drift. A one-dimensional lattice gas of [[EQUATION]]...

Dispersion of particulate matter from natural or anthropogenic sources into the atmosphere, such as that produced by volcanoes, fires, or industries, often causes severe damages. In particular, fine-sized particles are a serious threat to human health. Therefore, it is important to identify them...

Carbon lock-in has been used to explain the difficulty in reducing carbon emissions, while mission innovation policies have been proposed to break this path dependency, but the force of lock-in during the mission setting process is largely overlooked. In particular, the power of incumbents to...

This paper proposes a color picture encryption algorithm with pixel restructuring and quick diffusion to coexist the security and operational efficiency of the image encryption system. The algorithm employs a four-dimensional hyperchaotic system to decompose the pixels of a color image's three...

The deployment of renewable energy technologies in the home, such as heat pump systems, is increasingly encouraged in many countries to curb climate change and dependence on fossil fuels. However, the adoption process is not well-understood. In this paper, we develop an agent-based model to...

Exploring how finance can better support Grassroots Innovations (GIs), community-led solutions for net-zero transitions, we examine finance’s role in the case of UK community energy (CE) across three ‘diffusion pathways’: niche replication (growth in the numbers of projects), individual...

Clean energy communities (CEC) represent emerging socio-technical systems that offer a suitable alternative to non-sustainable energy production and consumption. Thus, CECs cultivate new knowledge of clean energy use and diffuse it among their members as well as interested publics outside the...

MEMS inertial sensors are oscillatory electro-mechanical devices that detect relative motion in an inertial frame. Frictional losses in these systems, expressed as a quality factor Q , directly have bearing on their absolute measurement accuracy, and hence on the duration of an acceptably...

We analyze the influence of the generalizations of hyperbolic (Cattaneo) heat equations (GCE) on temperature profile and photoacoustic signal for the two-layer samples. GCE extensions employ fractional-order derivatives related to the anomalous thermal diffusion in solid. We compare the...
