Position aware communication with noisy position measurements
2010 IEEE 21st International Symposium on Personal, Indoor and Mobile Radio Communications Workshops, 2010This paper presents capacity limits of novel position aware adaptive cellular communication systems exploiting channel state information (CSI) at the transmitter (CSIT). The position aware adaptive communication systems are benchmarked against state-of-the-art adaptive modulation and coding (AMC) systems that use only feedback or predict CSIT in ...

Position Measurement using Bluetooth
IEEE Transactions on Consumer Electronics, 2006A Bluetooth wireless indoor position-measurement system is described. Normal Bluetooth operation uses receiver signal strength indicator (RSSI) for automatic transmitter power control to ensure satisfactory received signal-to-noise ratio. This feedback system was disabled and a novel use of RSSI allowed a series of measurements to be made. The distance

Measurements of shoulder prosthesis positioning
International Congress Series, 2004Introduction One of the most difficult aspects of shoulder arthroplasty is retroversion. The ideal angle is about 30 of posterior rotation of humeral head with regard to the frontal plane so that the humeral head squarely faces the glenoid surface in the resting position.

When researchers want to assess positive feelings, they need to understand the various definitions and models of emotion. The current chapter describes the theories and various measures that derive from them, and reviews the strenghts and weaknesses of different measures of positive emotions.

Exploring the dynamic measurement of position
Proceedings. Sixth International Symposium on Wearable Computers,, 2003This paper describes the development of several methods for the dynamic measurement of error distribution for positioning systems. When a user moves along a path at an unknown speed, it is no longer feasible to calculate the distance between the measured and real positions. We outline three applications using different positioning systems and apply our
