Polymer solar cells are a low-cost alternative to inorganic photovoltaics, but reaching commercially viable efficiencies is heavily dependent on understanding and control of the polymer blend morphology in the devices, no matter which polymer is used. On page 499 of this issue, Nichole Cates Miller and colleagues construct the eutectic phase diagram of(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)
b S Supporting Information ' INTRODUCTION Conjugated polymers have received a great deal of attention because of their applications in photovoltaic devices, light-emitting diodes (LEDs), field-effect transistors (FET), and electrochromic devices. 1À5 Similarly, conjugated oligomers 6 share many of the properties of conjugated polymers with certain(More)
We are working on a revolutionary scintillating plastic material in the form of a fused fiber structure. The material has different responses to fast neutrons, gamma rays and thermal neutrons. Energy deposited in 3-D voxels will be recorded using SiPM technology. This material development is directed towards the urgent need for high resolution imaging of(More)
This paper proposes several extensions to IEEE Wireless Personal Area Network (WPAN) MAC protocol in order to enable a more robust and flexible solution to WPANs and sensor networks. Specifically, four extensions are proposed: a priority access period is added to handle emergency data transmission needed in some use cases, a scheduling protocol to resolve(More)
