Location-based service (LBS) systems have recently become a subject of active research and development. A key issue in such systems is efficient management of current and past location information of moving items. In the past two years, we have been establishing a new LBS system architecture, named the GALIS (gracefully aging location information system), which is based on the new approach of using...
Techniques for systematic derivation of tight service time bounds of subsystems of distributed real-time embedded computing systems, are a key for enabling practical and highly meaningful certification of timeliness of systems, which is the most challenging part of the reliability certification process. An approach which uses a hybrid of measurement-based statistical derivation approaches and worst-case...
The rectal “inflammatory cloacogenic polyp” is a recognized pathologic entity in adulthood. We report three cases in children aged between 8 and 12 years. This disorder should be included in the differential diagnosis in patients with hematochezia and tenesmus. These polyps are usually located at the anorectal junction and so may be overlooked at colonoscopy unless an endoscopic retroflexion maneuver...
