WINTER DAMAGE TO PEACHES

Applying Stochastic Small-Scale Damage Functions to German Winter Storms

Analyzing insurance loss data we derive stochastic storm damage functions for residential buildings. On district level we fit power law relations between daily loss and maximum wind speed, typically spanning more than 4 orders of magnitude. The estimated exponents for 439 German districts roughly range from 8 to 12. In addition, we find correlations among the parameters and socio-demographic da...

PEACHES and Peers

How to distribute resource locators is a fundamental problem in PKI. Our PKI Resource Query Protocol (PRQP), recently presented at IETF, provides a standard method to query for PKI resources locators. However the distribution of locators across PKIs is still an unsolved problem. In this paper, we propose an extension to PRQP in order to distribute PRQP messages over a Peer-to-Peer (P2P) network...

Protecting Stone Fruit Flower Buds from Winter Freeze Damage

Flower buds of peach, apricot, and sweet cherry are killed by low temperatures during winter and spring. Frost protection measures used commonly in the spring are applied to freeze protection during the winter in the Yakima Valley of Washington. Critical temperatures change rapidly during winter. To succeed, winter freeze protection requires adequate inversions, equipment that operates at tempe...

Control of Enzymatic Browning in Frozen Peaches

Relationship of base temperature to development of winter wheat

Development of wheat (Triticum spp.) is primary driven by temperature, but is also affected by other factors such as vernalization and photoperiod. Crop growth and development are often described in terms of calendar days. However, determining the development in terms of thermal time or physiological time is more accurate because it is an accumulation of the caloric energy needed for the o...
