Power control mitigates interference and maintains required QoS levels in cellular wireless networks. An important class of distributed power control (DPC) was proposed by Foschini and Miljanic in 1993, with many variants developed since. Almost all related work focuses on the equilibrium and asymptotic convergence properties. However, for many applications transient behavior is more important....

Direct primary care (DPC) is an emerging practice alternative that (1) eliminates traditional third-party fee-for-service billing and (2) charges patients a periodic fee for primary care services. We describe the DPC model by identifying DPC practices across the United States; distinguish it from other practice arrangements, such as the "concierge" practice; and describe the model's pricing usi...

In this paper a novel DPC strategy for Doubly-Fed Induction Generation (DFIG) based wind energy generation system with Indirect Matrix Converter (IMC) is proposed. The DPC with IMC deals with several main characteristics which makes it very suitable for DFIG. By suitably selecting switching pattern, the strategy is able to improve the steady state and transient response behaviors of the machine...

In this paper, differential phase imaging (DPC) with transmitted light is implemented by adding a suitable detection system to a standard commercially available scanning confocal microscope. DPC, a long-established method in scanning optical microscopy, depends on detecting the intensity difference between opposite halves or quadrants of a split photodiode detector placed in an aperture plane. ...

Direct primary care (DPC) is a growing movement across the United States involving at least 429 practices in 47 states. Family medicine physicians operating DPC practices share several characteristics: • They charge a periodic (monthly or annual) fee for a defined set of primary care services, • They do not bill any third parties on a fee-for-service basis for the services covered by the period...

This paper presents the design and analysis of a compensation method with application to a 345 kV 480 MVA three-phase transmission line. The compensator system includes a series injected voltage source converter that minimizes the resonance effects of capacitor line reactance. This creates an ability to compensate for the effects of subsynchronous resonance and thereby increase line loadability...

In this paper, a linearized time-invariant voltage-sensorless direct power control (DPC) with balanced and unbalanced dc-link voltage is proposed in three-phase Vienna rectifier. To achieve sensorless voltage, the architecture consists of three sub-architectures, including 1) linear control; 2) virtual flux, input active reactive estimators; 3) zero crossing distortion capacitor unbalance compe...

A voltage source inverter (VSI) is the key component of grid-tied AC Microgrid (MG) which requires a fast response, and stable, robust controllers to ensure efficient operation. In this paper, fuzzy logic controller (FLC)-based direct power control (DPC) method for photovoltaic (PV) VSI was proposed, modelled by modulating MG’s point common coupling (PCC) voltage. This paper also introduces mod...

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...
