Conventional approaches to the generation of referring expressions place the task within a pipelined architecture, typically somewhere between text planning and linguistic realisation. In this paper, we look at the issues that arise in generating one-anaphoric referring expressions; examination of this task causes us to reflect on the current predominant architectural models for natural languag...

This paper proposes an extended reference current calculation method for the PV based three-level neutral point clamped (NPC) shunt active power filter (SAPF). Shunt active power filter demands a source of energy for compensating the current based distortions, which utilizes the photovoltaic array with DC-DC boost converter as a source of DC power. The shunt connected inverter controls the DC l...

This paper is focused on the reference current calculation in the compensation mode of the active DC traction substations. The so-called p-q theory of the instantaneous reactive power is used as theoretical foundation. The compensation goal of total compensation is taken into consideration for the operation under both sinusoidal and nonsinusoidal voltage conditions, through the two objectives o...

This paper presents Cerberus, an eÆcient system for simulating the execution of shared-memory multiprocessor programs on a uniprocessor workstation. Using EDS (execution driven simulation), it generates address traces which can be used to drive cache simulations on the y, eliminating the large disk space requirements needed by trace les. It is fast because it links the program to be traced toge...

The exponential behaviour of the voltage-to-current characteristic is of primary importance because it enables us to construct a current source, which delivers a current that is proportional to the absolute temperature (PTAT). This can be used to implement a mechanism of temperature compensation in a bandgap reference circuit [8]. The conventional diode has an exponential voltage-to-current rel...

In this paper, a novel stator current based Model Reference Adaptive System (MRAS) estimator for speed estimation in the speed-sensorless vector controlled induction motor drives is presented. In the proposed MRAS estimator, measured stator current of the induction motor is considered as a reference model. The estimated stator current is produced in an adjustable model to compare with the measu...

This paper presents two recursive schemes for current reference generation for shunt active filters under unknown fundamental frequency. The schemes are based on the liner Kalman filter that needs the knowledge of the fundamental frequency. In practice, the fundamental frequency of the power system grid can vary. If it differs from the fundamental frequency considered in the mathematical model ...

A CMOS inverting type second generation current conveyor ‘positive’ (ICCII+) is presented which is based on voltage and current mirror circuits. PSPICE simulation results of the proposed structure using 0.5 μm MIETEC CMOS process parameters show that it is suitable for wideband applications and has got a wide output current swing with small current tracking error.
