The grating-based x-ray differential phase contrast (DPC) CT is emerging as a new technology with the potential for extensive preclinical and clinical applications. In general, the performance of an imaging system is jointly determined by its signal property (modulation transfer function–MTF(k)) and noise property (noise power spectrum–NPS(k)), which is characterized by its spectrum of noise eq...

An efficient method for raising the effectiveness and performance of fuel cell electric vehicles (FCEVs) is dynamic programming controller (DPC). By using real-time data to optimize control inputs, FCEVs can achieve higher levels efficiency reduce their environmental impact. The DPC algorithm works by solving an optimization problem at each time step, based on current state vehicle its environm...

AIM This was to evaluate the clinical and radiographic outcomes of direct pulp capping (DPC) therapy in primary molar teeth following haemostasis with various antiseptics for 12 months. MATERIALS AND METHODS A total of 70 vital primary molar teeth with deep dentin caries were randomly allocated to different antiseptic groups. After observing the pinpoint exposure, 0.9% saline solution (SS,...

INTRODUCTION Pulp vitality and its continuous dentin prodution are essential for long-term success of direct pulp capping (DPC). The aim of present study was to evaluate the histopathological response of the canine pulp following DPC using either different dentin adhesive resins (DAR), calcium hydroxide (CH) or mineral trioxide aggregate (MTA). METHODS AND MATERIALS DPC was done on 72 dog's t...

Direct torque control (DTC) is a fast and simple torque control method for induction motor without speed sensor. Conventional AC-DC-AC converter has a large DC link capacitor and low power factor in the input power line. In the matrix converters the DC link capacitor can be reduced and the unity input power factor can be obtained. In this paper a new method for direct torque and stator flux con...

The downlink of a multiple-input multiple output (MIMO) broadcast channel (BC) is considered, where each receiver is equipped with a single antenna and the transmitter performs nonlinear Dirty-Paper Coding (DPC). We present an efficient algorithm that finds the optimum transmit filters and power allocation as well as the optimum precoding order(s) possibly affording time-sharing between individ...
