In recent years, the Wireless Sensor Networks (WSNs) have grown dramatically in many fields such as military applications, environmental applications, and health assistant applications. However, there are numerous problems associated with applying the WSNs. Such problems are related to power consumption, performance, reliability, installation cost, and

An analysis of low-energy charged pion-nucleon data from recent pp experiments is presented. From the scattering lengths and the Goldberger-Miyazawa-Oehme ~GMO! sum rule we find a value of the pion-nucleon coupling constant of f 50.075660.0007. We also find, contrary to most previous analyses, that the scattering volumes for the P31 and P13 partial waves are equal, within errors, corresponding ...

In the (ab) polarized Raman scattering spectra of NaV2O5 single crystals, measured with 647.1 nm laser line at T < Tc, we found two modes at 86, and 126 cm not previously reported. These two modes, together with 66, and 106 cm modes, make an array of four low-energy equidistant modes below the energy onset of the continuum at about 132 cm. All four modes are strongly suppressed by increasing Na...

Embedded processor and SoCs are used in many devices, ranging from pace makers, sensors, phones, and PDAs, to general-purpose handheld computers and laptops. Each of these devices has their own requirements for performance, power dissipation, and energy usage, and typically implements a particular tradeoff among these entities. Allowing components of these devices to be controlled by software h...
