Background Nepal has made remarkable improvements in maternal health outcomes. The implementation of demand and supply side strategies have often been attributed with the observed increase in utilization of maternal healthcare services. In 2005, Free Delivery Care (FDC) policy was implemented under the name of Maternity Incentive Scheme (MIS), with the intention of reducing transport costs asso...

This study was designed to investigate whether follicular dendritic cells (FDC) can activate B cells to a state in which they can function as effective antigen-presenting cells (APC). High buoyant density (i.e., resting) B cells specific for 2,4-dinitro-fluorobenzene (DNP) were incubated with DNP-ovalbumin (OVA) bearing FDC, after which their capacity to process and present to an OVA-specific T...

BACKGROUND Patients with type 2 diabetes mellitus often take multiple anti-diabetic drugs for a long period. Fixed dose combination (FDC) therapy is expected to improve drug adherence for patients with diabetes. The effect of switching from a loose dose combination (LDC) regimen to an FDC regimen at equivalent dosage on glycemic control has not been evaluated fully. Therefore, we investigated t...

This paper proposes an efficient control framework that utilizes de-de converters to achieve flexible power flow control in multiterminal de (MTDC) grids. The de-de converter employed in this paper is connected in cascade with the de transmission line, and is therefore named cascaded power flow controller (CPFC). In this paper, a two-layer control strategy is developed for the operation and con...

Grid-forming inverter control plays an important role in ensuring frequency and voltage stability a microgrid (MG). This paper proposes novel power the αβ domain. The proposed method includes two loops; outer loop for droop inner output control. With controller, active reactive powers can be controlled according to simple complex principles described only αβ-domain. Controller gain tuning both ...

A phase interpolator (PI) based fractional divider is used to improve the quantization noise shaping properties of a 1-bit ∆Σ frequency-to-digital converter (FDC). Fabricated in 65nm CMOS process, the prototype calibration-free fractional-N Type-II PLL employs the proposed FDC in place of a high resolution TDC and achieves -102dBc/Hz in-band phase noise and 852fsrms integrated jitter (1k-40M) w...

The non-deterministic nature of power fluctuations in renewable energy sources impose challenges to the design DC voltage-droop controller Multi-Terminal High-Voltage (MTDC) systems. Fixed droop control does not consider converters’ capacity and system operational constraints. Consequently, an adaptive is counseled for appropriate demand distribution. previous studies based on Available-Headroo...

Virtual impedances are often used in droop-controlled paralleled-voltage-sourced inverters (VSIs) to achieve proper power sharing. However, different and unknown output of VSIs will affect the decoupling sharing performances. To solve this problem, article proposes a novel controller for by using disturbance observer (DOB). The DOB is adopted observe currents without any extra current sensors. ...

In recent years, there has been a fast growth in wind energy conversion system (WECS). There are two general types of wind turbines in WECS: fixed speed wind turbines and varying speed wind turbines.Permanent magnet synchronous generator (PMSG) is one of the most attractive generators for the varying speed turbine WECS.In this paper, a fuzzy controller is proposed to control the current source ...

Quadrotor control has been noted for its trouble as the consequence of the high maneuverability, system nonlinearity and strongly coupled multivariable. This paper deals with the simulation depend on proposed controller of a quadrotor that can overcome this trouble. The mathematical model of quadrotor is determined using a Newton-Euler formulation. Fractional Order Proportional Integral Derivat...
