Ventilation flow in commercial livestock buildings can be estimated by means of relatively simple indirect methods based on carbon dioxide (CO2), moisture or heat balances. However, ventilation flow on an hourly basis for these balances needs adjustment for diurnal variation in animal CO2 and heat production. This work examines the agreement between ventilation flow measured in a pig house over...

Renewable energies play a significant role to mitigate the impacts of climate change. In countries like Spain, there is potential wind energy production which might be key resource. this research, we obtain power at 80 m height and turbine (assuming specific turbine). To achieve objective produce an optimal mapping hourly “instantaneous surface speed” (height 10 m), based on available data. An ...

An analysis of ozone (O3) concentrations and several other air quality-related variables was performed to elucidate their relationship with visibility at five urban and semi-urban locations in the southeast United States during the summer seasons of 1980-1996. The role and impact of O3 on aerosols was investigated to ascertain a relationship with visibility. Regional trend analysis over the 198...

Abstract Bhubaneswar is the first designed ‘smart city’ in India and has experienced rapid urbanization since 2000. The question undertaken this study to assess if there a change rainfall over rapidly urbanizing region, so, what are characteristics of change? broader intent understand interlinked? Meteorological Department (hourly station daily gridded) Tropical Rainfall Measurement Mission (3-...

The field of building energy management, which monitors and analyses the energy use of buildings with the aim to control and reduce energy expenditure, is seeing a rapid evolution. Automated meter reading approaches, harvesting data at hourly or even half-hourly intervals, create a large pool of data which needs analysis. Computer analysis by means of machine learning techniques allows automate...

The patterns of feed intake when animals are allowed ad libitum access to feed in a respiration chamber is not known, nor are the potential effects of the artificial environment of chambers on voluntary feed intake. The objectives of the study were to describe the pattern of hourly feed intake of sheep when fed for ad libitum intake in respiration chambers and determine the repeatability of thi...
