Estimating Energy Savings in Smart Street Lighting by Using an Adaptive Control System
The driving force behind the smart city initiative is to offer better, more specialized services which can improve the quality of life of the citizens while promoting sustainability. To achieve both of these apparently competing goals, services must be increasingly autonomous and continuously adaptive to changes in their environment and the information coming from other services. In this paper ...
متن کاملThe Possibility of Using Watermelon Waste in Laying Hens Diets
In this experiment 240 Hy-Line (W-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. The amounts of watermelon skin meal (WSM) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. The results showed that using WSM up to 2% significantly improved the performance and...
متن کاملAhemeral lighting of turkey breeder hens. 2. Early age at lighting and reproductive performance.
An experiment was conducted to determine whether ahemeral lighting (AH) could be used to obtain increased egg weight and poult weight and otherwise normal reproductive performance in Large White turkey hens lit as early as 26 wk of age. The experimental design utilized a 2 x 2 factorial arrangement of treatments that evaluated two light cycle lengths (24 h, control and 28 h, ahemeral) at two he...
متن کاملModeling Energy Utilization in Broiler Breeders, Laying Hens and Broilers
The factorial approach has been used to partition the energy requirements into maintenance, growth, and production. The coefficients determined for these purposes can be used to elaborate energy requirement models. These models consider the body weight, weight gain, egg production, and environmental temperature to determine the energy requirements for poultry. Predicting daily energy requiremen...
متن کاملErysipelothrix rhusiopathiae in Laying Hens
The bacterium Erysipelothrix rhusiopathiae can infect a wide range of mammals (including humans) and birds. Disease outbreaks (erysipelas) have been considered unusual in chickens internationally, but outbreaks with high mortality and egg production losses have been diagnosed in Swedish laying hen flocks every year since 1998. Different aspects of E. rhusiopathiae infection in chickens were exa...
