Calibration-less direct capacitor-to- microcontroller interface

A new technique to measure a capacitor or a capacitive sensor by means of a direct sensor-to-microcontroller interface circuit that does not need a calibration capacitor is proposed. Basically, the measurement process consists of three consecutive steps of charge, discharge and charge of the capacitor under test. A non-linear equation is obtained and solved that is dependent only on known circu...

Direct Interface Tracking of Droplet Deformation

Direct interface tracking computes spray behavior based only on first principles. It is an advanced form of direct numerical simulation, but with the emphasis shifted from resolving details of turbulence to details of multiphase flow. The moving interface requires special treatment and advanced numerical methods. A code that is capable of accurate resolution of three-dimensional free-surface de...

A Direct Manipulation User Interface for QueryingGeographic

This paper presents an architecture for a direct manipulation user interface for browsing and querying geographic data. This interface provides users with a high level object oriented conceptual view of the underlying database, independent of the database's native data model. It lets users manipulate diierent representations of a single georeferenced entity, thereby adding a new degree of exibi...

The Degradation Interface of Magnesium Based Alloys in Direct Contact with Human Primary Osteoblast Cells

Magnesium alloys have been identified as a new generation material of orthopaedic implants. In vitro setups mimicking physiological conditions are promising for material / degradation analysis prior to in vivo studies however the direct influence of cell on the degradation mechanism has never been investigated. For the first time, the direct, active, influence of human primary osteoblasts on ma...
