Database-as-a-Service (DAS) is an emerging database management paradigm wherein partition based index is an effective way to querying encrypted data. However, previous research either focuses on one-dimensional partition or ignores multidimensional data distribution characteristic, especially sparsity and locality.

Over the summer month of August 2008, Georgia launched a large-scale military offensive against South Ossetia in an attempt of reconquering the territory. Four years later, on October 1, 2012, Georgia is holding its first Parliamentary Elections after the conflict that caused so much harm.

Protecting main memories from soft errors typically requires special dual-inline memory modules (DIMMs) which incorporate at least one extra chip per rank to store error-correcting codes (ECC). This increases the cost of the DIMM as well as its power consumption. To avoid these costs, some proposals have suggested protecting non-ECC DIMMs by allocating

Managing knowledge in large organizations is a challenge in itself. Modern views on Knowledge Management (KM) focus not only on finding ways to capture and distribute corporate knowledge but also provide ways through which knowledge can be shared, discussed and created. Different types of organizations have different approaches to KM.
