Activity Inference for Ambient Intelligence Through Handling Artifacts in a Healthcare Environment

  • Francisco E. Martínez-Pérez,
  • Jose Ángel González-Fraga,
  • Juan C. Cuevas-Tello and
  • Marcela D. Rodríguez

20 January 2012

Human activity inference is not a simple process due to distinct ways of performing it. Our proposal presents the SCAN framework for activity inference. SCAN is divided into three modules: (1) artifact recognition, (2) activity inference, and (3) act...

Computer Reconstruction of Plant Growth and Chlorophyll Fluorescence Emission in Three Spatial Dimensions

  • Chandra Bellasio,
  • Julie Olejníčková,
  • Radek Tesař,
  • David Šebela and
  • Ladislav Nedbal

18 January 2012

Plant leaves grow and change their orientation as well their emission of chlorophyll fluorescence in time. All these dynamic plant properties can be semi-automatically monitored by a 3D imaging system that generates plant models by the method of code...

FBG Sensor for Contact Level Monitoring and Prediction of Perforation in Cardiac Ablation

  • Siu Chun Michael Ho,
  • Mehdi Razavi,
  • Alireza Nazeri and
  • Gangbing Song

17 January 2012

Atrial fibrillation (AF) is the most common type of arrhythmia, and is characterized by a disordered contractile activity of the atria (top chambers of the heart). A popular treatment for AF is radiofrequency (RF) ablation. In about 2.4% of cardiac R...

Optimal Methods of RTK-GPS/Accelerometer Integration to Monitor the Displacement of Structures

  • Jinsang Hwang,
  • Hongsik Yun,
  • Sun-Kyu Park,
  • Dongha Lee and
  • Sungnam Hong

17 January 2012

The accurate measurement of diverse displacements of structures is an important index for the evaluation of a structure’s safety. In this study, a comparative analysis was conducted to determine the integrated RTK-GPS/accelerometer method that can pr...
