The increasing urban population requires rapid housing construction. Rising global temperatures have led to more space cooling options inside buildings. There is a need design new-age buildings with sustainable, thermal comfort, and energy-efficiency approach. present work integrates this approach into the of prefabricated elements. Locally available co-fired ash, along other sustainable altern...

Since 2007, coal-fired electricity generation in the US has declined by a stunning 25%. At the same time, natural gas-fired generation and wind generation have dramatically increased due to technological advances and policy interventions. We examine the joint impact of natural gas prices and wind generation on coal generation, with a particular focus on the interaction between low natural gas p...

BACKGROUND Air pollution is known to cause respiratory disease. Unlike motor vehicle sources, fuel-fired power plants are stationary. OBJECTIVE Using hospitalization data, we examined whether living near a fuel-fired power plant increases the likelihood of hospitalization for respiratory disease. METHODS Rates of hospitalization for asthma, acute respiratory infection (ARI), and chronic obs...

Unbalanced energy consumption in the production of ceramic artifacts is responsible for considerable undesirable impacts, such as increased emissions polluting gases, excessive fuel materials, land degradation, and unpredictable financial costs. By contrast, practice optimizing sintering, which associated with firing high temperature, can result productivity reduced costs preserving an environm...

The following is a proof which is independent of this characterisation. First assume that ‖ ‖ is non-archimedean. Let x, y ∈ K. Using that ‖ ‖ extends | | we then obtain |x + y| = ‖x + y‖ ≤ max{‖x‖, ‖y‖} = max{|x|, |y|} which shows that | | is non-archimedean. Now assume that | | is non-archimedean. Let x, y ∈ K̂. Let ε > 0. Since K is dense in K̂ there exist u, v ∈ K such that ‖x − u‖ < ε and ‖y...

∆u = ∂2u ∂x1 + ∂2u ∂x2 where x = (x1, x2) ∈ IR 2 are Cartesian coordinates. Even though the Poisson equation looks very special it is an important model case representing several problems from physics based on energy minimisation. Variations of the techniques we will study apply to a wide class of second order so-called elliptic problems. It is known that there are cases where no classical (i.e...

LEGOsheets was created. LEGOsheets is an educational environment implemented in Agentsheets, a grid-based tool for creating visual programming languages [5]. Programming can serve as a vehicle to create learning opportunities in the constructionist sense [3]. The LEGO1 Programmable Brick gives children the ability to create physical artifacts, such as vehicles and robots, and program them with ...

In this paper, we discuss the applicat[ons ant! implications of the Programmable Brick-s-s tiny, portable computer embecfded ~nside a LE~Q'J brick, capable of interacting with the phys!cal world in a large variety of ways. We describe how Programmable Bricks make possible a wide range of new design activities for children, and we discuss experiences in using Programmable Bricks in three types o...
