“…We calculated the temperature dependent of magnetoresistance (MR) of LTCMO with x=0.0, 0.125 and 0.25 using the conductivity values form the transport calculations using the software BoltzTraP which utilized the output of Quantum Espresso. We use Mott's two current model to evaluate the MR ratio of LTCMO [7], MR = [( where and represent the conductivity of spin up and spin down electrons. Table 4 3+ bond angle will be more difficult to saturate as the increase competition between double exchange and superexchange interactions that will lead to canting of the manganese moments and hence reduce the magnetic properties of material.…”

There has been a tremendous growth in multimedia applications over wireless networks. Wireless Multimedia Sensor Networks(WMSNs) have become the premier choice in many research communities and industry. Many state-of-art applications, such as surveillance, traffic monitoring, and remote heath care are essentially video tracking and transmission in WMSNs. The transmission speed is constrained by big size of video data and fixed bandwidth allocation in constant routing path. In this paper, we present a CamShift based algorithm to compress the tracking of videos. Then we propose a bandwidth balancing strategy in which each sensor node is able to dynamically select the node for next hop with the highest potential bandwidth capacity to resume communication. Key to the strategy is that each node merely maintains two parameters that contains its historical bandwidth varying trend and then predicts its near future bandwidth capacity. Then forwarding node selects the next hop with the highest potential bandwidth capacity. Simulations demonstrate that our approach significantly increases the data received by sink node and decreases the delay on video transmission in Wireless Multimedia Sensor Network environment.

“…In the past couple decades, tremendous effort has been put forth towards incorporating thin-film magnetic cores into integrated passive circuit elements, including inductors and transformers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], for a variety of applications. The traditional operating frequency and flux-amplification properties of integrated magnetic films have made them ideal for power management applications up to now [1][2][3][4][5][6][7][8][15][16][17][18]. However, the cost of depositing such films thick enough for power electronics devices has limited their usage in integrated systems to date.…”

The demand on mobile electronics to continue to shrink in size while increase in efficiency drives the demand on the internal passive components to do the same. Power amplifiers require inductors with small form factors, high quality factors, and high operating frequency in the single-digit GHz range. This work explores the use of magnetic materials to satisfy the needs of power amplifier inductor applications. This paper discusses the optimization choices regarding material selection, device design, and fabrication methodology. The inductors achieved here present the best performance to date for an integrated magnetic core inductor at high frequencies with a 1 nH inductance and peak quality factor of 4 at ∼3 GHz. Such compact inductors show potential for efficiently meeting the need of mobile electronics in the future.
