Device to device (D2D) underlying massive MIMO cellular network is a robust deployment which enables enhance its throughput. It also improves services and applications for the proximity-based wireless communication. However, an important challenge in such mutual interference. Interference, uplink spectrum, reusing same resource with user, caused by D2D users. In this paper, we study distributed...

Radiator arrays with Dynamic Polarization Control (DPC) and 2D beam steering enable polarization matching to the receiver antenna regardless of its polarization, orientation, and location. A fully integrated 122.9 GHz 2x2 DPC multi-port driven phased array radiates all linear polarizations (0°-180° polarization angles) with axial ratios above 14 dB, and controls the axial ratio from 1.2 dB (cir...

Inferring regulatory relationships among many genes based on their temporal variation in transcript abundance has been a popular research topic. Due to the nature of microarray experiments, classical tools for time series analysis lose power since the number of variables far exceeds the number of the samples. In this paper, we describe some of the existing multivariate inference techniques that...

INTRODUCTION The aim of this trial was to compare clinical and radiographic success rates of direct pulp capping (DPC) using a novel biomaterial called Calcium Enriched Mixture (CEM) cement versus Mineral Trioxide Aggregate (MTA) in primary molar teeth. MATERIALS AND METHODS In this randomized clinical trial 42 deciduous molars in 21 patients who had at least two teeth requiring DPC, were tre...

Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...

The Direct Power Contro; has many advantages like it avoids the usage of integration of PWM voltages which leads to stable operation even at zero rotor frequency, it is position sensor less and hence will not depend on machine parameters like stator or rotor resistance. In case of network unbalance, if the system is operated with constant active and reactive powers, it leads to oscillations in ...

i ntroduction: nano-hydroxyapatite (nha) has been used for regeneration of osseous defects. calcium-enriched mixture (cem) cement is also used for various dental treatments. this trial compared the efficacy of nha and cem cement for direct pulp capping (dpc) of sound primary teeth. methods and materials: in this randomized clinical trial with split-mouth design, after attaining informed consent...
