Rapid acquisition by sequential excitation and refocusing (RASER) is a new ultrafast MRI technique (1). It provides single-shot images that are purely T2-weighted, so there are no artifacts due to T2 * effects that plague EPI. RASER shows promise for fMRI studies in areas of the brain that are difficult to image with EPI (2, 3). The basis of RASER is time-encoding, which uses a frequency-swept ...

Shunt capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power system. Studies show that a flat voltage profile on the system can significantly reduce line losses. Shunt capacitor banks are relatively inexpensive and can be easily installed anywhere on the network. This paper reviews principles of shunt capacitor bank design for substatio...

in this article, a multi-objective function for placement of distributed generation (dg) and capacitors with thetap setting of under load tap changer (ultc) transformer is introduced. most of the recent articles have paidless attention to dg, capacitor placement and ultc effects in the distribution network simultaneously. insimulations, a comparison between different modes was carried out with,...

Multiple hybrid energy storage systems (HESSs) consisting of batteries and super-capacitors (SCs) are widely used in DC microgrids to compensate for the power mismatch. According their specific characteristics, SCs low-frequency high-frequency mismatches, respectively. This paper proposes a decentralized allocation strategy dynamically forming multiple HESSs aided with novel buffer. The buffer ...

This paper focused on the development of capacitor voltage balancing methods in a flying capacitor multilevel inverter (FCMLI) fed induction motor drive. For improving the performance of flying capacitor multilevel inverter, a switching pattern selection scheme is implemented. The proposed method has been designed a seven-level flying capacitor multilevel inverter by using sinusoidal pulse widt...

This paper shows that a highly deformable capacitor made of a soft dielectric and two conformal electrodes can switch between two states discontinuously, by a first-order transition, as the total charge varies gradually. When the total charge is small, it spreads evenly over the area of the capacitor, and the capacitor deforms homogeneously. When the total charge is large, it localizes in a sma...

This reduces capacitor voltage fluctuation without using voltage feedback and RLC Filter circuits connected in parallel with...

In this paper, the optimal placement and sizing of capacitors for compensation reactive power unbalance in medium voltage distribution networks with unbalanced loads is proposed. The proposed capacitor allocation reduces losses caused by demand unbalance. powers are calculated IEEE STD 1459-2010, presented real values electrical magnitudes three-phase systems. results obtained from method compa...

We present a network of dynamic capacitance sharing (DCS) switched-capacitor converters that increase the range of efficient voltage regulation for multiple independent loads while reducing area overhead. Since maximum power dissipation is fixed for a single chip due to thermal constraints, the proposed converters consider the overall power budget of multiple voltagescalable loads to dynamicall...

A method to eliminate the effect of capacitor mismatch for a switched-capacitor DAC is described. The method consists of two elements. The first element is the use of a compensating switching algorithm, which can eliminate the effect of capacitor mismatch only for some digital input values. The second element is that each digital word is written as the sum of two other words for which the capac...
