ASCENT: Adaptive self-configuring sensor networks topologies
, 2004
"... Advances in microsensor and radio technology will enable small but smart sensors to be deployed for a wide range of environmental monitoring applications. The low per-node cost will allow these wireless networks of sensors and actuators to be densely distributed. The nodes in these dense networks w ..."

Jigsaw: Solving the puzzle of enterprise 802.11 analysis
- In SIGCOMM
, 2006
"... The combination of unlicensed spectrum, cheap wireless interfaces and the inherent convenience of untethered computing have made 802.11-based networks ubiquitous in the enterprise. Modern universities, corporate campuses and government offices routinely deploy scores of access points to blanket thei ..."

multiple monitors to provide a single unified view of all physical, link, network and transport-layer activity on an 802.11 network. To drive this analysis, we have deployed an infrastructure of over 150 radio monitors that simultaneously capture all 802.11b and 802.11g activity in a large university
Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

the expected value (EV) of the probability distribution and thus the theoretically expected payoff of an option, according to EV = i (p i · x i ); i = 1, n; n = number of rewards. With increasing numbers of trials, the measured mean of the actually occurring distribution will approach the expected value
A Radio Spectrum Measurement Platform for Spectrum Surveying in Cognitive Radio
"... Abstract. This paper presents a sophisticated radio spectrum measure-ment platform specifically envisaged and designed for spectrum occu-pancy surveys in the context of Dynamic Spectrum Access/Cognitive Ra-dio (DSA/CR). The presented tool is a very flexible computer-controlled radio measurement syst ..."

Statistics of Cone Responses to Natural Images: Implications for Visual Coding
- Journal of the Optical Society of America A
, 1998
"... ted in the first stage of retinal processing, the photoreceptor layer. In this work we measure the spectral distributions of light present in natural images by using a hyperspectral camera, 12--15 which provides a complete spectrum at each pixel. We derive human cone responses at each spatial loc ..."

"... Abstract In developing countries, unexpected income shocks are common but informal insurance is typically incomplete. An important question is therefore whether risk-sharing within the household is e¤ective. This paper presents results from a …eld experiment with 142 married couples in Kenya in whi ..."

informal systems of gifts and loans to pool idiosyncratic risk. While these informal networks do provide some protection against shocks, they also face substantial problems of asymmetric information and payment enforceability, and existing evidence suggests that inter-household risk sharing networks
Spectrum Occupancy Analysis for Cognitive Radio
"... Abstract: Observations provide evidence that the licensed spectrum is by far not fully used neither in time nor in space. Cognitive radio, which can sense its environment and location and then alter its frequency, modulation and other parameters so as to dynamically reuse the available spectrum, cou ..."

Continued Radio Monitoring of the Gamma Ray Burst 991208
, 2002
"... We present radio observations of the afterglow of the bright γ-ray burst GRB991208 at frequencies of 1.4, 4.9 and 8.5 GHz, taken between two weeks and 300 days after the burst. The well-sampled radio light curve at 8.5 GHz shows that the peak flux density peaked about 10 days after the burst and dec ..."

it is assumed that the broadband emission originates from a synchrotron spectrum, while the time-evolution of the break frequencies and peak flux density are solved for explicitly. Although the decay indices for most of the synchrotron parameters are similar to the jet model, the evolution of the cooling break
Time series modelling of spectrum occupancy for cognitive radio
"... Cognitive radio requires real time monitoring of the spectrum to determine the frequency of transmission. Spectrum analysers tend to employ a slow frequency sweep and hence such measurements can only be used for modelling of the spectrum, which can provide vital information for frequency planning an ..."

Measuring the Similarity of Vector Fields Using Global Distributions
"... Abstract. Sensors such as video surveillance and weather monitoring systems record a significant amount of dynamic data which are represented by vector fields. We present a novel algorithm to measure the similarity of vector fields using global distributions that capture both vector field properties ..."
