The Wasabi Personal Shopper (WPS) is a domainindependent database browsing tool designed for on-line information access, particularly for electronic product catalogs. Typically, web-based catalogs rely either on text search or query formulation. WPS introduces an alternative form of access via preference-based navigation. WPS is based on a line of academic research called FindMe systems. These ...

Traditionally, geostatistical algorithms are contained within specialist GIS and spatial statistics software. Such packages are often expensive, with relatively complex user interfaces and steep learning curves, and cannot be easily integrated into more complex process chains. In contrast, Service Oriented Architectures (SOAs) promote interoperability and loose coupling within distributed syste...

service oriented enterprises (soes) are subject to constant change and variation. in this paper, the changes are considered from an economic perspective based on service culture notion. once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. we construct a game theoretic model trying to capture the possible conflicting i...

Many efficient algorithms and architectures have been proposed for the design of low complexity fir filter. In order to design the filter a bit-parallel multiple constant multiplication (MCM) operation which dominates the complexity of the digital signal processing ,where the most importance is given to digitserial MCM design which also offers the low complexity MCM operations instead of increa...

certain advantages of service-oriented architecture have led to the spread of this type of architecture around the world. however, some special features of this type of architecture have led to more compromise between the security in the information system and other information systems. the purpose of this paper is to identify and examine the impact of factors and dimensions of the information ...

Producing customized base maps generated by automated generalisation on the web is an important issue in physical planning. In this web context an interoperable architecture is a key requirement. It integrates the necessary data and the functionality to finally perform the generation of the base map. Additionally, interoperability increases the reuse of the architecture for other domains. In th...
