Cortina is an energy-efficient indoor localization system, which leverages a wireless sensor network to support navigation and tracking applications. To improve the localization performance, we develop a hybrid ranging system, which incorporate both RSS and RToF-based techniques. To overcome effects from indoor multipath, we design and implement algorithms(More)
The tags also include an accelerometer for activity recognition, and a barometric pressure sensor to accurately detect the floor plan. We have conducted experiments over a 2000 m 2 area instrumented with eighteen sensor nodes. Our initial results show that the system can track people in real-time with an average error of 2.8 m. I. INTRODUCTION In the past(More)
Stability in transgene inheritance and expression is an important consideration in utilizing transgenic germplasm for the development of commercially viable transgenic crops. In the present study, inheritance of the carotenogenic transgene encoding enzyme phytoene synthase (psy) was studied in rice through PCR analysis in F2, BC1F1 (Swarna X F1), its(More)
