Dairy farms confront unique risks from weather conditions. Hot and humid weather induces heat stress, which reduces both the quantity and quality of dairy production. Traditional heat abatement technologies control the environment through ventilation, misting or evaporative cooling. Adoption of abatement equipment, however, is hindered by its high initial cost and possibly long payback period, ...

The impressive growth of the aviation industry and number flights entail several environmental repercussions, such as increased aircraft noise emissions. With worrying complaints from communities around airports comes also distrust in numerical models used for prediction. In this study, we compare ‘Dutch model’ predictions to measured values NOise MOnitoring System (NOMOS) Amsterdam Airport Sch...

Three families of road noise prediction models can be distinguished depending on the way they account for traffic flow. Static noise models only consider free-flow constant-speed traffic with uniformly distributed vehicles. Analytic noise models assume that all vehicles are isolated from one another but account for their mean kinematic profile over the network. Micro-simulation noise models rel...

COSMA Community Orientated Solutions to Minimize Aircraft Noise Annoyance was a European approach within the 7th Framework Programme of the European Commission. Aircraft noise engineering is focused more or less on the reduction of the noise emission for single aircraft components, and separately treating the noise abatement procedures during take-off and landing. COSMA’s aim was to combine bot...

This paper explores the significance of policy-induced technological change for the design of carbon-abatement policies. We derive analytical expressions characterizing optimal CO2 abatement and carbon tax profiles under different specifications for the channels through which technological progress occurs. We consider both R&D-based and learning-by-doing-based knowledge accumulation, and examin...

The impact of induced technological change (ITC) in energy/climate models on the timing of optimal CO2-abatement depends on whether R&D or learning-by-doing (LBD) is the driving force. Bottom-up energy system models employing LBD suggest strong increases in optimal early abatement. In this paper we extend an existing top-down model supporting this view according to the notion that socio-economi...

The deployment of measures to mitigate sound during propagation outdoors is most often a compromise between the acoustic design, practical limitations, and visual preferences regarding landscape. current study raised berm next highway shows number common issues like impact limited length noise shielding device, initially non-dominant sounds becoming noticeable, local drops in efficiency when ba...
