Towards Automated Yield Estimation in Viticulture

Forecasting the grape yield of vineyards is of critical importance in the wine industry, as it allows grape growers to more accurately and confidently invests in capital equipment, negotiate pricing, schedule labour and develop marketing strategies. Currently, industry standard forecasts are generated by manual sampling of bunch weights, grape size, grape numbers and seasonal predictions which ...

Precision Viticulture- A Mechanized Systems Approach

Winegrowers and winemakers have always been a special group of producers not only because of their product that can be manipulated from rootstock all the way to final bottling, but also because of their very special language. Winegrowers speak of phylloxera, Pierce's Disease, Botrytis cinerea, canopy management, veraison, anthocyanins and tannins until the average person looks askance at the sp...

Modelling Ammonium Transporters in Arbuscular Mycorrhiza Symbiosis

The Stochastic Calculus of Wrapped Compartments (SCWC) is a recently proposed variant of the Stochastic Calculus of Looping Sequences (SCLS), a language for the representation and simulation of biological systems. In this work we apply SCWC to model a newly discovered ammonium transporter. This transporter is believed to play a fundamental role for plant mineral acquisition, which takes place i...

Hyperspectral Image Analysis for Precision Viticulture

We analyze the capabilities of CASI data for the discrimination of vine varieties in hyperspectral images. To analyze the discrimination capabilities of the CASI data, principal components analysis and linear discriminant analysis methods are used. We assess the performance of various classification techniques: Multi-layer perceptrons, radial basis function neural networks, and support vector m...
