Integration of Spatio-temporal Data in a DBMS

This paper presents Spanar Antenna designed using CST Microwave Studio Simulation 2011. The proposed antenna was designed to operate at 10 GHz, which suggested return loss, S11 must be less than -10 dB and voltage standing wave ratio (VSWR) must be less than 2. The best performance of simulation of Spanar Antenna was obtained at a small size of 24.8 mm × 8.0 mm with dimension board of FR4 substrate 31.7 mm × 18.5 mm. The thickness (h) and dielectric constant (er) of substrate were 1.6 mm and 4.7. An analysis between simulation result and measurement result has been compared in order to see the antenna performance.

Pseudonmization techniques for clinical data: Privacy study in Sultan Ismail Hospital Johor Bahru

In this paper we describe a new proposed framework in implementation of spatio-temporal data types in DBMS environment. This can be achieved by extending an existing DBMS with new data type as spatio-temporal data. This base type is generic and can be used for any DBMS operation. On top of these generic types we build high-level data-mining operators.
