Michael D. Powell, Arijit Biswas, Joel S. Emer, Shubhendu S. Mukherjee, Basit R. Sheikh, Shrirang Yardi
2009 2009 IEEE 15th International Symposium on High Performance Computer Architecture  
Because the computations utilize few inputs, CAMP is simple enough to implement in hardware, providing run-time structure and core power estimates for dynamic power management.  ...  Designers must employ aggressive power-management techniques at run-time to keep a processor's ballooning power requirements under control.  ...  Because the computations utilize few inputs, CAMP is simple enough to implement in hardware, providing run-time structure and core power estimates for dynamic power management.  ...

Dendritic geometry shapes neuronal cAMP signalling to the nucleus

Lu Li, Nicolas Gervasi, Jean-Antoine Girault
2015 Nature Communications  
We combine diffusion-reaction modelling and live imaging to investigate cAMP-activated DARPP-32 signalling to the nucleus.  ...  Neurons have complex dendritic trees, receiving numerous inputs at various distances from the cell body. Yet the rules of molecular signal propagation from dendrites to nuclei are unknown.  ...  Two firstorder chemical reactions were used to model PKA translocations with parameters estimated by an approach similar to the one used for DARPP-32 and were validated with the published data 65 .  ...

Unsupervised change detection in the feature space using kernels

Michele Volpi, Devis Tuia, Gustavo Camps-Valls, Mikhail Kanevski
2011 2011 IEEE International Geoscience and Remote Sensing Symposium  
The resulting difference kernel, that is a combination of kernels computed on the coregistered and radiometrically matched input images, is used to train a nonlinear partitioning algorithm.  ...  In order to apply the kernel k-means, issues related to the initialization and to the tuning of parameters (e.g. the Gaussian RBF bandwidth) are considered.  ...  Kernel parameters estimation To estimate the kernel parameters, we propose a simple solution reducing the problem to the estimation of two parameters shared by each group of information (σ single and σ  ...

GNSS-R Altimetry Performance Analysis for the GEROS Experiment on Board the International Space Station

Adriano Camps, Hyuk Park, Ivan Sekulic, Juan Rius
2017 Sensors  
If the transmitted power is 3 dB higher (likely to happen at beginning of life of the GNSS spacecrafts), mission requirements (rms error is <50 cm) are met for all ISS heights and for U 10 up to 15 m/s  ...  However, around 1.5 GHz, the ionosphere can induce significant fading, from 2 to >20 dB at equatorial regions, mainly after sunset, which will seriously degrade the altimetry and the scatterometry performances  ...  Acknowledgments: This work has been performed during the ESA GEROS-ISS Phase A study led by Astrium Defence and Space (Spain). It has also been sponsored by projects ref.  ...

A Risk Based Approach to Limit the Effects of Covert Channels for Internet Sensor Data Aggregators for Sensor Privacy [chapter]

Camilo H. Viecco, L. Jean Camp
2009 IFIP Advances in Information and Communication Technology  
However, an organization that participates in a sensor network risks providing a covert channel to attackers if that organization's sensor can be identified.  ...  Effective defense against Internet threats requires data on global real time network status. Internet sensor networks provide such real time network data.  ...  This parameter is used to estimate the cost for an attacker. The running time of an algorithm describes a bound on the number of operations needed to complete the algorithm.  ...
