Several techniques exist to select and materialize a proper set of data in a suitable structure that manage the queries submitted to the online analytical processing systems. These techniques are called view management techniques, which consist of three research areas: 1) view selection to materialize, 2) query processing and rewriting using the materialized views, and 3) maintaining materializ...

Without further ado, we present the P3-game. The P3-game is decidable for elementary classes of graphs such as paths and cycles. From an algorithmic point of view, the connected P3-game is fascinating. We show that the connected P3-game is polynomially decidable for classes such as trees, chordal graphs, ladders, cacti, outerplanar graphs and circular arc graphs.

this paper presents a new arc starter circuit that is usable in manual metal arc welding (mma) power supplies. the proposed circuit uses an auxiliary circuit and a series coupling transformer for adding high frequency spikes to output dc voltage during arc striking. the proposed circuit is usable in inverter based arc welding supplies and it could result in a decrease of weigh, volume and expen...

We present a multi-view annotation framework for Chinese treebanking, which uses dependency structures as the base view and supports conversion into phrase structures with minimal loss of information. A multi-view Chinese treebank was built under the proposed framework, and the first release (PMT 1.0) containing 14,463 sentences is be made freely available. To verify the effectiveness of the mu...

A graph is said to be half-arc-transitive if its automorphism group acts transitively on the set of its vertices and edges but not on the set of its arcs. With each half-arc-transitive graph of valency 4 a collection of the so called alternating cycles is associated, all of which have the same even length. Half of this length is called the radius of the graph in question. Moreover, any two adja...

A 49-year-old woman with a history of juvenile hypertension since 4 years of age was referred to our hospital. She had previously experienced a subarachnoid hemorrhage at 18 years of age. Her blood pressure (BP) had been wellcontrolled (under 130/90 mmHg) with antihypertensive treatment. Contrast-enhanced computed tomography showed a narrowing of the interrenal abdominal aorta with ostial steno...
