In order to facilitate query processing, the information contained in data warehouses is typically stored as a set of materialized views. Deciding which views to materialize presents a considerable challenge. The task is to select from a very large search space a set of views that minimizes view maintenance and query processing costs. Heuristic methods have(More)
In order to facilitate efficient query processing, the information contained in data warehouses is typically stored as a set of materialized views. Deciding which views to materialize represent a challenge in order to minimize view maintenance and query processing costs. Some existing approaches are applicable only for small problems, which are far from(More)
Mitochondrial complex II (CII) has been recently identified as a novel target for anti-cancer drugs. Mitochondrially targeted vitamin E succinate (MitoVES) is modified so that it is preferentially localized to mitochondria, greatly enhancing its pro-apoptotic and anti-cancer activity. Using genetically manipulated cells, MitoVES caused apoptosis and(More)
Reliable prediction of stability changes in protein variants is an important aspect of computational protein design. A number of machine learning methods that allow a classification of stability changes knowing only the sequence of the protein emerged. However, their performance on amino acid substitutions of previously unseen non-homologous proteins is(More)
The need for efficient access and management of time dependent data in modern database applications is well recognised and researched. Existing access methods are mostly derived from the family of spatial R-tree indexing techniques. These techniques are particularly not suitable to handle data involving open ended intervals, which are common in temporal(More)
Due to the lack of in-built tools to navigate the web, people have to use external solutions to find information. The most popular of these are search engines and web directories. Search engines allow users to locate specific information about a particular topic, whereas web directories facilitate exploration over a wider topic. In the recent past,(More)
Efficient management of multidimensional data is a challenge when building modern database applications that involve many fold data such as temporal, spatial, data warehousing, bio-informatics, etc. This problem stems from the fact that multidimensional data has no order that preserves proximity. The majority of existing solutions to this problem cannot be(More)
Radio Frequency Identification refers to wireless technology that uses radio waves to automatically identify items within certain proximity. This process involves tagging items with a transmitter which will emit bursts of information including, but not limited to, the identification of the tag. There are three main varieties of tags: Active, Semi-active and(More)
