We report here the fabrication of fiber chromatic dispersion compensators, along with the tests of those components in wavelength-division-multiplexed transmission at 10 Gb/s and an analysis of their performance by simulation.

Power electronic devices such as Flexible AC Transmission Systems (FACTS), both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the shunt-connected FACTS controllers family, the Static Synchronous Compensator...

The combination of Multiple Input Multiple Output (MIMO) with Orthogonal Frequency Division Multiplexing (OFDM) is a promising technique for high performance with very high data rates in 4G broadband wireless communications. However, the non-linearities caused by the High Power Amplifier (HPA) degrade the performance of MIMO-OFDM systems. In this paper, we present a theoretical analysis of nonl...

FIR (Finite impulse response) digital filters are known to have some very desirable properties such as linear phase, stability, and absence of limit cycle. However their applications generally require more computation. In this paper we consider the simple method to design a multiplier-less narrowband FIR filter. The method is based on well known IFIR (Interpolated FIR) structure. The novelty of...

Given a right coprime MFD of a strictly proper plant P(s) = NR(s)DR(s)−1 with DR(s) column proper a simple numerical algorithm is derived for the computation of all polynomial solutions [X L (s), YL (s)] of the polynomial matrix Diophantine equation X L (s)DR(s)+YL (s)NR(s) = DC (s) which give rise to the class Φ(P, DC ) of proper compensators C(s) := X L (s)−1YL (s) that when employed in a uni...

A number of requirements are imposed on installations associated with regulated DC sources, including low voltage and current ripple in the load, as well a wide range output variation. Such traditionally made controlled rectifiers or pulse-width converters which ripples always present.

The capability of routing power from one phase to another, interphase flow (IPPF) control, has the potential improve systems efficiency, stability, and operation. To date, existing works on IPPF control focus unbalanced compensation using three-phase devices. An model is proposed for capturing general caused by single-phase elements. reveals that presence a quantity in line-to-line elements cau...

BACKGROUND For treatment of the entire cranium using passive scattering proton therapy (PSPT) compensators are often employed in order to reduce lens and cochlear exposure. We sought to assess the advantages and consequences of utilizing compensators for the treatment of the whole brain as a component of craniospinal radiation (CSI) with PSPT. Moreover, we evaluated the potential benefits of sp...

In this paper, a linear parametric friction model is formulated by linearizing a nonlinear empirical friction model in parameters. A proposed decompositionbased control design framework is applied to synthesize the friction compensation scheme. A separate compensator is designed for each type of friction utilizing the most suitable control technique. The nominal friction is compensated by feedf...
