## Abstract Drought prediction for in many regions of the world has critical importance for strategic planning agriculture and water management. The occurrence of droughts cannot be predicted with certainty and thus must be treated as random variables. It is the main purpose of this paper to develo
## Abstract This paper demonstrates a method for quantitatively determining the spatially resolved contact resistance of silicon solar cells. Contactβresistance maps obtained by this technique on screenβprinted industrial silicon solar cells are presented and discussed. Extending the contactβresist
