Today’s storage interfaces hide device-specific details, simplifying system development and device interoperability. However, they prevent database systems from exploiting devices’ unique performance characteristics. Abstract and device-independent annotations to existing storage interfaces can cleanly expose key device characteristics that improve performance and simplify manual tuning. By aut...

This paper describes an emulation based approach to develop and test future applications and services in Ad-hoc and heterogeneous network environments. For the development of applications and services in Ad-hoc and heterogeneous networks it is important to consider the characteristics of each network type. This is contrary to the traditional goal of network stacks and middleware solutions which...

This paper examines the connection of immigration and diversity to homicide by advancing a recently developed approach to modeling spatial dynamics-geographically weighted regression. In contrast to traditional global averaging, we argue on substantive grounds that neighborhood characteristics vary in their effects across neighborhood space, a process of "spatial heterogeneity." Much like treat...

AIMS To examine the effect of subatmospheric steam treatment on total viable counts (TVCs) on bovine hide and on the quality of derived leather. METHODS AND RESULTS Pieces of bovine hide were heated to 75 degrees C (+/-2 degrees C) (n = 3) or 80 degrees C (+/-2 degrees C) (n = 3) for periods of 1, 10 or 20 s by the application of steam at subatmospheric pressure in a laboratory scale apparatu...
