This paper proposes an OFDM based adaptive modulation scheme employing variable coding rate (VCR OFDM AMS), which selects optimum modulation and coding scheme (MCS) realized by combination of several modulation schemes and coding rates. The OFDM AMS with multilevel transmit power control (OFDM AMS/MTPC) can realize high data rate transmission in the dynamic parameter controlled-orthogonal frequ...

In modern endodontics, vital pulp therapy (VPT) has been considered an ultra-conservative treatment modality. Based on the level of pulp preservation, VPT includes stepwise excavation, indirect pulp capping (IDPC), direct pulp capping (DPC), miniature pulpotomy (MP), partial/Cvek pulpotomy and coronal/complete pulpotomy (CP). The present article reviews the treatment outcomes of 94 permanent te...

INTRODUCTION The aim of this study was to evaluate the clinical and histological status of the pulp in sound human premolars after direct pulp capping (DPC) with four different DPC methods/materials. METHODS AND MATERIALS This study was conducted on eight volunteers who had to extract four first premolars due to orthodontic treatment. Subsequent to tooth isolation, standardized class I occlus...

introduction: the aim of the present study was to evaluate the expression of fibronectin (fn) and tenascin (tn) after direct pulp capping (dpc) in dogs’ teeth with either mineral trioxide aggregate (mta), propolis or platelet-rich plasma (prp), by means of immunohistochemistry. methods and materials: a total of 48 sound molars and premolars with mature apices from four dogs, were included. the ...

Different types of decentralized clustering problems have been studied so far for networks and multi-agent systems. In this paper we introduce a new type of a decentralized clustering problem for networks. The so called Decentralized Packet Clustering (DPC) problem is to find for packets that are sent around in a network a clustering. This clustering has to be done by the routers using only few...

This research focuses on the analysis and design of robust direct power control (DPC) for a shunt active filter (SAPF). The study proposes novel switching table based an impact inverter vectors derivatives instantaneous reactive powers. goal is to reduce number commutations by eliminating null while maintaining desired DC-bus voltage using PI regulator-based anti windup technique. Additionally,...

This paper describes the analysis and design of a low cost three phase inverter brushless dc motor (BLDC) drive.For effective utilization of the developed system, a novel direct current controlled pwm scheme (DPC)is designed and implemented.. The operational principle of the four-switch BLDC motor drive and the developed control scheme are theoretically analyzed and the performance is demonstra...

INTRODUCTION In contrast to estradiol action, little is known about androgen signaling in placental development. The purpose of this study was to evaluate the impact of diminished androgen action on hypoxia inducible factor 1a (HIF-1a) and vascular endothelial growth factor A (VEGFA) protein expression as well as their mRNAs in the structures of fetal and maternal parts of porcine placenta duri...

Direct primary care (DPC), a reformulation of concierge medicine, has intrinsic appeal to overburdened physicians. Its advocates promise a competitive income at a fraction of the volume of patient responsibilities, and they claim it as a patient-friendly, consumer-driven strategy that can meet the needs of patients across the economic spectrum. In my observation, DPC membership fees are typical...
