ells that passively swell and contract with changes in osmolarity are the key to detecting those changes, say Most cells have at least two mechanisms for maintaining homeostasis in response to changes in salt concentrations. Without these mechanisms, osmotic forces take over: more water and thus less salt outside cells leads water to flood into a cell. But this swelling doesn't occur in most ce...

Cell volume and dry mass are typically correlated. However, in this issue, Zlotek-Zlotkiewicz et al. (2015. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201505056) and Son et al. (2015. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201505058) use new live-cell techniques to show that entry to mitosis coincides with rapid cell swelling, which is reversed before division.

Abstract The purpose of this paper is to describe the design a Hybrid Series Active Power Filter (HSeAPF) system improve quality power on three-phase distribution grids. controls are comprise Pulse Width Modulation (PWM) based Synchronous Reference Frame (SRF) theory, and supported by Phase Locked Loop (PLL) for generating switching pulses control Voltage Source Converter (VSC). DC link voltage...

In this paper, grid disturbances like asymmetrical sag and swell faults in phase-A are analyzed for the grid connected DFIG. The dynamic behavior of DFIG is compared and tabulated with results using state error compensators like PI, PI with resonant (PIR) and internal model control (IMC) on rotor side converter (RSC). The RSC is designed analytically with enhanced field oriented control (EFOC) ...

Synthetic Aperture Radar (SAR) Interferometry (InSAR), using data from the European Space Agency satellites ERS1 and ERS2, is being used to image, survey and map surface movement of the London region. Local and regional movement due to shrink and swell of the London Clay geology, tunnelling, and possibly ground water abstraction has been investigated here for the first time by InSAR. Cyclic ann...

This paper proposes a low complexity control scheme for voltage of dynamic restorer (DVR) in three-phase system. The employs the fractional order, proportional-integral-derivative (FOPID) controller to improve on DVR performance order enhance power quality terms response time, steady-state error and total harmonic distortion (THD). result obtained was compared with proportional-integral (FOPI),...

Abstract—This paper presents comparative study and implementation of Unified Power Quality Conditioner (UPQC) to eliminate harmonics and reactive power compensation in a single-phase to threephase converter system. The proposed configuration solves typical problems encountered in remote rural area applications, where only a single-phase supply is available and there is a demand for three-phase ...

Wind power generation is grasping more attention nowadays because it offers the benefits of reduced cost, increased efficiency, less pollution and so on. But the known disadvantage is that the integration of wind farm with grid leads to many power quality problems such as voltage sag, swell, unbalance, harmonics, flickers etc. This paper concentrates mainly on diminution of source voltage sag a...
