Reconstruction of temporal-spatial profile from participatory sensing data using Compressive Sensing
The reconstruction of an unknown temporal-spatial profile from participatory sensing data poses a number of challenges due to uncoordinated user movement and possibly low user involvement. This paper considers the problem of reconstructing such a profile from participatory sensing data by exploiting the theory of compressive sensing. In particular we study the impact of the number of users and ...
Introduction: We have investigated cardiac SPECT with slant hole collimator in which the holes are slanted towards the target organ, to provide greater sensitivity over the parallel hole collimator. In addition, parallel hole collimator was used to obtain a comparison in FWHM, sensitivity, Compton and photoelectric area values in the simulations. Materials and Methods...
The flight profile of typical small unmanned air systems (UAS) has expanded in the last decade beyond those encountered by traditional fixed-wing transport and rotary-wing aircraft. These new flight conditions may involve unusual flight mechanics as with flapping wing flight or complex aerodynamics when performing difficult maneuvers as part of routine operations. Such scenarios typically invol...
Chengkuo Lee National University of Singapore Department of Electrical and Computer Engineering 4 Engineering Drive 3 Singapore, Singapore 117576 E-mail: [email protected] Abstract. The characteristics of biochemical sensors based on photonic crystal (PC) resonators are investigated in this work. The PC structure consists of holes arranged in a hexagonal lattice on a silicon slab. The nanoring r...
We developed a micro-gas detector based on a Fabry-Pérot (FP) cavity embedded in a microfluidic channel. The detector was fabricated in two steps: a silicon substrate was bonded to a glass slide curved with a micro-groove, forming a microfluidic FP cavity; then an optical fiber was inserted through a hole drilled at the center of the groove into the microfluidic FP cavity, forming an FP cavity....
Doping Pr in 123-systems gives rise to some anomalies, such as critical Temperature suppression. Here, we show that a modification of hole localization theory based on a geometrical modeling by band percolation theory can put forward as a good explanation for the critical temperature suppression for the whole range of Pr-doping value. In this model the key concept of hole clustering is introd...
