An automatic bird identification system is required for offshore wind farms in Finland. Indubitably, a radar the obvious choice to detect flying birds, but external information actual identification. We applied visual camera images as data. The proposed consists of radar, motorized video head and single-lens reflex with telephoto lens. A convolutional neural network trained deep learning algorithm image classification. also propose data augmentation method which are rotated converted...

Abstract Practical deterrent methods are needed to prevent collisions between birds and wind turbine blades for offshore farms. It is improbable that a single method would work all bird species in given area. An automatic identification system required order develop species–level methods. This the first necessary part of entirety eventually able automatically monitor movements, identify species, launch measures. A prototype has been built on Finnish west coast. In proposed system, separate...

Light quality response is a vital environmental cue regulating plant development. Conifers, like angiosperms, respond to the changes in light including level of red (R) and far-red (FR) light, which follows latitudinal cline. R FR wavelengths form significant component entire life cycle, initial developmental stages such as seed germination, cotyledon expansion hypocotyl elongation. With an aim identify differentially expressed candidate genes, would provide clue regarding genes involved...

An automatic bird identification system is required for offshore wind farms in Finland. Indubitably, a radar the obvious choice to detect birds but actual requires external information such as digital images. The final species based on fusion of data and image data. We applied deep learning method classification we developed expansion technique training present results classifier small convolutional neural network.

Abstract Climate change possess a threat to forests and forestry. Drought has been identified as one of the main issues due its interaction with other biotic abiotic stresses. Few studies have done regarding breeding effect on adaptability climate change. After common garden experiment seedling families Scots pine from northern Sweden, we found differences in drought tolerance between natural origin. We performed high throughput analysis-based phenotyping both canopy root traits. Root...
