Finite Fibonomial Operator Calculus (FFOC) is a special case of Extented Finite Operator Calculus (FOC). The ”Calculus of Sequences” was started by Ward in 1936 [1] and considered by many authors after him. The very foundations of FOC were given by O.V.Viskov, G. Markowsky and finally by the author of [8, 2, 3] . The idea of FFOC due to A.K.Kwaśniewski [2] (see Example 2.1) is now continued [4]...

In this paper, a flexible, high computation speed and cost effective field programmable gate array (FPGA)-based speed controller for an induction motor with field-oriented control, (FOC) is presented. All the control functions including the space vector modulation based PWM waveform generation, field-oriented control algorithm and rotor flux position estimation have been realized using FPGA to ...

1This paper presents a new speed observer for high performance FOC (Field Oriented Control) and DTC (Direct Torque Control) induction motor drives. It is an MRAS (Model Reference Adaptive Systems) observer which employs a linear ANN (Artificial Neural Network) for the estimation of both the rotor speed and the flux-linkage. The training of the ANN based adaptive model of the MRAS observer is pe...

This paper presents the design, analysis and implementation of speed control drive indirect Field Oriented Control (FOC) induction motor using a dSPACE DS1103 digital-signal-processorbased real-time data acquisition control system and MATLAB/Simulink environment. The details design of speed control indirect Field Oriented Control (FOC) induction motor drive with AntiWindup PI controllers' (AWPI...

Coccidiosis, the Eimeria spp infections, in goats is common and worldwide in distribution. Disease occurs in various age groups though most common during 2-6 months of age. Prevention of the disease mainly depends on maintenance of hygienic standards in farm premises. Treatment includes the use of Amprolium, Sulfonamides, Decoquinates, Toltazuril and Ionophores. Present study, however, describe...

5-methylcytosine (5-mC) can be sequentially oxidized to 5-hydroxymethylcytosine (5-hmC), 5-formylcytosine (5-foC), and finally to 5-carboxylcytosine (5-caC), which is thought to function in active DNA cytosine demethylation in mammals. Although the roles of 5-mC in epigenetic regulation of gene expression are well established, the effects of 5-hmC, 5-foC and 5-caC on DNA replication remain uncl...

We study an extension of first-order logic that allows to express cardinality conditions in a similar way as SQL’s COUNT operator. The corresponding logic FOC(P) was introduced by Kuske and Schweikardt [16], who showed that query evaluation for this logic is fixedparameter tractable on classes of databases of bounded degree. In the present paper, we first show that the fixed-parameter tractabil...

This paper explores the fourth order cumulants (FOC) of the LPC residual of speech signals and presents a new algorithm for Voice Activity detection (VAD) based on the newly established FOC properties. Analytical expressions for the horizontal slice of the 4th cumulant as well as the kurtosis of voiced speech are derived based on a reported sinusoidal model [4]. The derivations demonstrate that...

This Paper presents a comparative study of Genetic Algorithm method (GA) and Particle swarm optimization (PSO) method to determine the optimal proportional-integral (PI) and proportional-integral-derivative (PID) controller parameters, for speed control of a Field Oriented Control (FOC) induction motor. The FOC induction motor has been modeled in MATLAB (SIMULINK); the GA and PSO algorithm has ...
