This paper presents a modified nine switch inverter with two inputs and two Z-source networks. This inverter has two DC inputs and two AC outputs. Input DC voltages can be boosted to the required level. Amplitude, frequency and phase of AC output voltages can be controlled, independently. The proposed converter can be used in applications with two unregulated DC sources, which require feeding ...

Image restoration based on an `-data-fitting term and edge preserving total variation regularization is considered. The associated non-smooth energy minimization problem is handled by utilizing Fenchel-duality and dual regularization techniques. The latter guarantee uniqueness of the dual solution and an efficient way for reconstructing a primal solution, i.e. the restored image, from a dual so...

In this paper we propose a new large-update primal-dual interior point algorithm for P∗(κ) linear complementarity problems (LCPs). We generalize the analysis of BER’s primal-dual interior point algorithm for LP to P∗(κ) LCPs. New search directions and proximity measures are proposed based on a new kernel function which has linear growth term. We showed that if a strictly feasible starting point...

A rotational inertial navigation system (RINS) has been wildly used in long term marine navigation. In a dual-axis RINS, with all constant biases averaged out, the errors which can not be averaged out become the main error source. In this paper, the gyro geomagnetic biases of a dual-axis RINS are modelled, analysed and calibrated. The gyro geomagnetic biases are proved unable to be averaged out...

In recent years, ozone (O3) has gradually become the primary pollutant plaguing urban air quality. Accurate and efficient prediction is of great significance to prevention control pollution. The quality monitoring network provides multisource concentration data for prediction, but based on still faces challenges each station’s series data. Aiming at problems low accuracy computational efficienc...

The paper discusses the solution to the optimal adaptive control problem over an extended time horizon. This leads to a controller that has dual features, i. e.; it uses control actions as well as probing actions. The solution of the optimal dual control problem is intractable from a computational point of view. Approximations to obtain simpler suboptimal dual controllers are thus important.The...

background: the co-existence of under and overnutrition might be influenced by a marked shift in dietary and lifestyle practices of people in developing countries. objective: this study aims to identify the factors associated with the occurrence of a dual form of malnutrition in the same households in a rural district in peninsular malaysia. methods: this study was conducted in two phases. the ...

We investigate some syntactic properties of Wadler’s dual calculus, a term calculus which corresponds to classical sequent logic in the same way that Parigot’s λμ calculus corresponds to classical natural deduction. Our main result is strong normalization theorem for reduction in the dual calculus; we also prove some confluence results for the typed and untyped versions of the system.
