Hierarchical Materialisation of Method Results in Object-Oriented Viewsasonable to materialise also the intermediate results of methods called from m. We call this technique . When an object used to materialise the result of m is updated, then m has to be recomputed. This recomputation can use unaffected intermediate materialised results, thus reducing the recomputation time.

Distributed Searching of k-Dimensional Data with Almost Constant Costst cost in real distributed structures..Only worst case analysis has been previously considered and the almost constant cost for the amortized analysis of the general k-dimensional case appears to be very promising in the light of the well known difficulties in proving optimal worst case bounds for k-dimensions.

Caching for Mobile Communicationion remains valid. We use expiration timestamps to safeguard against using stale cached data. We study a variety of caching algorithms and a variety of methods for setting timestamps based on client mobility. We report results from simulation studies.

Wireless Mobile Communication and Healthcareproposed to support transaction semantics at mobile clients. The proposed protocol adopts . as the way of sending invalidation reports, in order to dynamically adapt to system workload (update pattern, data locality). We study the performance of the proposed protocol by means of simulation experiments.

https://doi.org/10.1007/978-3-031-60742-4en, based on structures of Gabow et al. [.] and Beam and Fich [.] we describe an index scheme, which handles in an efficient way window queries in spatial database applications. In the general case in which the plane has real coordinates the above time results are slowed down by adding a logarithmic factor due to the normalization technique.

Publishing Satire: Collective Humouron rules is often huge. However it is possible to represent it with usually much smaller set of representative rules. If needed, the user can derive all association rules from the set of representative rules syntactically by means of a cover operator. Incremental solutions of mining around representative rules are discussed in the paper as well.
