The goal of the AQuA architecture is to provide adaptive fault tolerance to distributed applications by using commercial off-the-shelf hardware and operating systems. The AQuA architecture allows application programmers to request desired levels of dependability during applications’ runtimes. It also provides adaptive fault tolerance. In distributed systems, resources change dynamically, and di...

Climate change has direct and indirect consequences on crop production and food security. Agriculture and cropproduction is one of the factors which depend on the weather conditions and it provides the human requirements inmany aspects. The objective of this study is to assess the impacts of future climatic change on irrigated rice yieldusing the CERES-Rice model in the Southern Coast of Caspia...

The title complex, aqua-[1,3-bis-(2,6-diiso-propyl-phen-yl)imid-az-ol-2-yl-idene](η(4)-cyclo-octa-1,5-diene)rhodium(I) tetra-fluor-ido-borate, [Rh(C(8)H(12))(C(27)H(36)N(2))(H(2)O)]BF(4), exihibits a square-planar geometry around the Rh(I) atom, formed by a bidentate cyclo-octa-1,5-diene (cod) ligand, an N-heterocylcic carbene and an aqua ligand. The complex is cationic and a BF(4) (-) anion ba...

z Abstract AQUA is an integrated resource management architecture for an end-system that can deliver desired QOS to multimedia applications. The proposed architecture (called AQUA for Adaptive End-system Quality of Service Architecture) includes a common framework for managing resources such as CPU, network interface, memory, and bus bandwidth. Contributions of AQUA include an adaptation framew...

In order to simulate growth and yield of crop in field scale, crop simulation models always require a lot of initial parameters. WebGIS is a powerful tool for obtaining, managing and analyzing spatial data on the Web. With the support of WebGIS, crop models based on web services can be easily run on the web by remote client and provide decision information and measures for crop production. In t...

Crop rotations are an important factor for the design and implementation of sustainable agricultural systems. Integrated agricultural land use models increasingly acknowledge the role of crop rotations by assessing economic and environmental impacts of agricultural production systems. However, insufficient data on crop rotations often challenge their implementation. In this article, we present ...

Building dependable distributed systems from commercial off-the-shelf components is of growing practical importance. For both cost and production reasons, there is interest in approaches and architectures that facilitate building such systems. The AQuA architecture is one such approach; its goal is to provide adaptive fault tolerance to CORBA applications by replicating objects. The AQuA archit...

BACKGROUND Aqua-cycling is easy to learn, acceptable, and safe for patients with knee osteoarthritis. It can therefore be an ideal component of aquatic circuit training. OBJECTIVE To investigate the feasibility of a small group-based aquatic exercise programme including aqua-cycling. DESIGN A feasibility study using quantitative (pre-post) and qualitative (cross-sectional) assessments. PA...
