‎in this paper‎, ‎we prove the nonexistence of two weighing matrices of‎ ‎weight 81‎, ‎namely $cw(88,81)$ and $cw(99,81)$‎. ‎we will apply two‎ ‎very different methods to do so; for the case of $cw(88,81)$‎, ‎we‎  ‎will use almost purely counting methods‎, ‎while for $cw(99,81)$‎, ‎we‎ ‎will use algebraic methods‎.

In recent years, total power dissipation and area are one of the most important challenges in VLSI design. By reducing the number of transistors in the circuits and the design structures are may occupied small area and ultra-low power design. In this project based on AND gates and full adders are designed using pass transistor logic (PTL) and different techniques are used for low power in AND G...

BACKGROUND Is existing provision of health services in Europe affordable during the recession or could cuts damage economic growth? This debate centres on whether government spending has positive or negative effects on economic growth. In this study, we evaluate the economic effects of alternative types of government spending by estimating "fiscal multipliers" (the return on investment for each...

The most area consuming arithmetic operations in high-performance circuit’s Finite Impulse Response (FIR) multiplication is one. We are using different types of multipliers to reducing the cost of effective parameters in FIR filter design. We use only truncated multipliers in design, by using these multipliers we consume some more area and power, and ineffective results in transposed form. The ...

the paper presents unified analytical solution for combining high-frequency and low-frequency economic time-series by additive and proportional denton methods with parametrical dependence on the initial values of variable and indicator in evident form. this solution spans denton’s original and cholette’s advanced benchmarking initial conditions as the subcases. computational complexity of the o...
