An adequate logic for full LOTOS

We present a novel result for a logic for symbolic transition systems based on LOTOS processes. The logic is adequate with respect to bisimulation defined on symbolic transition systems

An Examination of Manufactured Housing as a Community- and Asset-Building Strategy

An increasing share of lower-income families, the same population targeted by community-development organizations, are opting to live in housing that was built off-site in a factory to meet the performance standards of the national HUD manufactured-housing code. However, most community-development practitioners are just beginning to come to terms with the implications of manufactured housing for their work.This paper explores advantages and disadvantages of manufactured housing for those entities whose mission is community development and asset building. Several challenges are presented for practitioners: First, working to educate consumers while also creating financing processes that ensure manufactured home buyers obtain credit on the best terms for which they can qualify. Second, using the increased scrutiny under the Manufactured Housing Improvement Act of 2000 to advocate for states to enforce more rigorous installation standards and increased accountability. Third, working to overcome land-use controls which prevent manufactured homes from being placed in communities in need of affordable housing, as well as areas with more potential for appreciation. Fourth, working with designers and planners to develop innovative designs and housing developments, while maintaining manufactured housing's affordability advantages.Finally, equal effort must be devoted to address the difficult conditions of many lower-income people -- owners and renters alike -- living in older, and often deteriorating, mobile homes. While a few of these families and individuals could be relocated to new and better quality homes with the help of subsidies, resource limitations suggest the need to create cost-effective methods to eliminate health and safety problems by upgrading or rehabilitating this extremely affordable element of the nation's housing inventory.As a companion to this paper, an exhaustive literature review has been compiled

Efficiency of sprinkler irrigation systems

Shallow-rooted vegetable crops growing on sandy soils in hot, often windy summer weather, pose a difficult watering problem for most Western Australian vegetable growers. Irregularities in wetting patterns are common. Wind effects are seldom taken into account in system design. The increasing popularity of knocker-type sprinklers makes these considerations particularily important

Irrigating with underground water

MANY farmers in South-West areas are looking to irrigation to increase and diversify farm production, particularly on the sandy coastal plain where irrigation in summer is essential for vegetable, fruit and fodder production
