A 3D display using super high-density multiview images should enable reproduction of natural stereoscopic views. In the super multi-view display system, viewpoints are sampled at an interval narrower than the diameter of the pupil of a person’s eye. With the parallax produced by a single eye, this system can pull out the accommodation of an eye to an object image. We are now working on a real-t...

Updating a view requires deriving a translation which converts an update on a view into updates on underlying relations. We present a pragmatic approach that uses syntactic as well as semantic knowledge to decide an appropriate translation. The semantic knowledge belongs to database and application domains and is collected at view definition time as well as at view update time. We present a rul...

We consider the problem of updating databases through views composed of selections, projections, and joins of a series of Boyce-Codd Normal Form relations. This involves translating updates expressed against the view to updates expressed against the database. Previously, we enumerated all translations of view updates into database updates that satisfy five criteria. This enumeration shows that ...

This research reviews and tests two contradicting notions in cost stickiness literature by empirical recognition of the consequences of cost stickiness. Cost stickiness is consistent with both rational resource planning and opportunistic incentives of manager to increase personal benefits arising from status and power. Although both mechanisms involve asymmetric retention of slack, some of the ...
