Unlike microscopic physics models, agent-based artificial life models are commonly constructed without a strict energy conservation rule. We report on the effects of incorporating energy conservation in our predatorprey based agent model. We discuss the role of microscopic model parameters that give rise to macroscopic emergent effects that can be measured. Arguably nonconserving models like ou...

A conductive loop of wire moving with constant velocity in a magnetic field is one of the most used examples in physics textbooks in connection to the Faraday-Lenz law, highlighting the consistency of electromagnetism with the principle of conservation of energy. It is frequently concluded that currents are not induced in a perfectly conducting loop because an induced current would have to be i...

Educating on the knowledge of electric energy consumption and conservation has been becoming a focus and rather urgent issue in energy education. Although several researchers have attempted to apply teaching and learning strategies to promote students’ conceptual understanding on the topic, they still have sub-optimal conceptual understanding of what the major factors of energy consumption are....

A conservation law in a cellular automaton is the statement of the invariance of a local and additive energy-like quantity. This chapter reviews the basic theory of conservation laws in cellular automata. A general mathematical framework for formulating conservation laws in cellular automata is presented and several characterizations of them are summarized. Computational problems regarding cons...

Dual conservation laws of linear planar elasticity theory have been systematically studied based on stress function formalism. By employing generalized symmetry transformation or Lie–B€acklund transformation, a class of new dual conservation laws in planar elasticity have been discovered based on Noether theorem and its Bessel–Hagen generalization. These dual conservation laws represent variati...

In the last years, wireless sensor networks (WSNs) have gained increasing attention from both the research community and actual users. As sensor nodes are generally battery-powered devices, the critical aspects to face concern how to reduce the energy consumption of nodes, so that the network lifetime can be extended to reasonable times. In this paper we first break down the energy consumption ...

Energy education has been conducted to equip learners with relevant energy conservation knowledge for many years. However, learners seldom put the knowledge into practice and even have few ideas about how to reduce energy consumption. To this end, there is a need to address this issue to improve the efficiency of energy education. One of the strategies is digital game-based learning, which can ...

Fragment molecular orbital molecular dynamics (FMO-MD) with periodic boundary conditions is performed on liquid water using the analytic energy gradient, the electrostatic potential point charge approximation, and the electrostatic dimer approximation. Compared to previous FMO-MD simulations of water that used an approximate energy gradient, inclusion of the response terms to provide a fully an...

This paper analyzes different existing projects about pervasive persuasive games for energy conservation. The design, pervasiveness, persuasion methods and long term results are discussed for each of them. by comparing them on different aspects, some points appear more valuable than other to achieve long term goals. A set of important elements for a successful game is then derived from the comp...
