Abstract This article analyzes the economic impact of pandemic, providing insights into consequences alternative policies. Our framework focuses on three key features: (i) The coronavirus disease (COVID-19) is a sectoral shock unknown depth and duration affecting some sectors technologies more than others; (ii) there are constraints in shifting resources across sectors; (iii) high level uncerta...

Multipliers are the fundamental arithmetic unit in multimedia and digital signal processing applications. The fixed width multipliers are used in those applications where we have to maintain a fixed format and allow a little accuracy loss of output data. In this paper we have proposed a low power technique for high speed modified booth multiplication. Even though modified booth multiplier reduc...

| In this paper, we apply constrained least squares solution (CLS) to the problem of reducing the number of operations in FIR digital lters with a motivation of reducing its power consumption. The constraints are deened by the maximum allowable add/subtract operations in forming the products which are used in computing the output. We show that truncation and rounding of coeecients can be viewed...

The sectoral structure of most agricultural enterprises is unbalanced and uncoordinated, which underlies the need in deepened research of its improvement. This paper is dedicated to the formation and evaluation of the sectoral structure with the use of mathematical methods of data processing. Mathematical economic modeling based on optimization and simulation models has been applied for the for...

It is well-known that linear constrained model predictive control has a nonlinearity that is continuous and piecewise affine. Under certain feasibility conditions the nonlinearity may be sector bounded and shown to satisfy sufficient conditions for the existence of Zames-Falb multipliers. Thus the nonlinearity satisfies a wide class of integral quadratic constraint (IQC). Standard analysis then...

In this paper we proposed an efficient structure for sampling rate conversion by rational factor of L/M, where L is upsampling factor and M is downsampling factor. In this method, the coefficient symmetry of the linear phase filter is used. In this way, the number of required multiplications per output sample is reduced. For implementation we use linear phase FIR filter. The symmetric FIR filte...

Working papers are preliminary documents circulated to stimulate discussion and obtain comments The Sectoral Activities Department is part of the Social Dialogue Sector of the ILO. Its objective is to promote social dialogue at the sectoral level and to facilitate the exchange of information among the ILO's constituents on labour and social developments concerning particular economic sectors. O...

This paper deals with the problem of guaranteed cost analysis and control of a class of nonlinear discrete-time systems with uncertain parameters. We use polynomial Lyapunov functions to derive stability conditions with a guaranteed bound on the 2-norm of the performance output in terms of linear matrix inequalities (LMIs). We then extend this approach to control design by considering parameter...

This paper examine Lilien’s sectoral shifts hypothesis for Japan for different age cohorts. Previous studies of the sectoral shifts hypothesis for Japan have for the most part concentrated on the relationship between aggregate unemployment and sectoral shifts, and are typically not supportive of the hypothesis. However, recent increases in the unemployment rates of the young and the aged sugges...
