We present a new technique for proving AC-termination. We show that if certain conditions are met, AC-termination can be reduced to termination, i. e., termination of a TRS S modulo an AC-theory can be inferred from termination of another TRS R with no AC-theory involved. This is a new perspective and opens new possibilities to deal with AC-termination.

This review concentrates on the effect of activated carbon (AC) addition to membrane bioreactors (MBRs) treating wastewaters. Use of AC-assisted MBRs combines adsorption, biodegradation and membrane filtration. This can lead to advanced removal of recalcitrant pollutants and mitigation of membrane fouling. The relative contribution of adsorption and biodegradation to overall removal achieved by...

Fixed multi-beam base stations can significantly increase the capacity of WCDMA systems. Previous capacity studies have not included important Radio Network Algorithms (RNA) such as Admission Control (AC) which are essential to guarantee an acceptable Quality Of Service (QoS). Some of these RNA may have to be changed to secure the full gains of fixed multi-beam antennas. In this paper two downl...

Multi-phase (more than three-phase) converters are required mainly for feeding variable speed multi-phase drive systems. This paper discusses one such solution by using direct ac-ac converter that can be used to supply a five-phase two-motor drive system. Matrix converter based two-motor drive system is presented for the first time in this paper. Two stator windings of two five-phase machines w...

This paper proposes the concept of three phase ac to ac resonant converter for Induction heater. As compared with basic converters, ac to ac resonant converter has advantages of less components count, low cost, high reliability and better efficiency. A closed loop control structure is proposed in this paper for controlling three phase resonant converter. Finally, this proposed system is experim...

In this paper the control algorithm for a novel five-phase matrix converter under balanced input voltage conditions is proposed. This algorithm is essentially based on the indirect space vector modulation. The complete algorithm, analysis and the model of the proposed matrix converter are introduced. The model has been applied for the case of inductive loads. The simulation results of input-out...

In this paper, the indirect matrix converter is systematically studied with the single-pole-multiple-pole representation. A carrier based PWM algorithm is developed in two steps. First, the continuous modulation functions for all the throws are derived based on the desired sinusoidal input currents. Then the switching functions are derived from the modulation functions with focus on the zero cu...

Numerical integration methods are used to approximate the definite integral of a function. Various methods exist such as the Midpoint, Trapezoidal and Simpson Rules. The different methods that exist tend to offer a tradeoff between simplicity and accuracy. Simpson’s method is the most accurate of the aforementioned methods and is used in the LV2 INS calculations. Simpson’s method is one that as...

In this paper, the reactive power control of a variable speed permanent-magnet synchronous wind generator with a matrix converter at the grid side is improved. A generalized modulation technique based on singular value decomposition of the modulation matrix is used to model different modulation techniques and investigate their corresponding input reactive power capability. Based on this modulat...

This paper presents first an overview of the wellknown voltage and current dc-link converter topologies used to implement a three-phase PWM ac–ac converter system. Starting from the voltage source inverter and the current source rectifier, the basics of space vector modulation are summarized. Based on that, the topology of the indirect matrix converter (IMC) and its modulation are gradually dev...
