In this paper a new nonlinear guidance law with finite time convergence is proposed. The second order integrated guidance and control loop is formulated considering a first order control loop dynamics. By transforming the state equations to the normal form, a finite time stabilizer feedback linearization technique is proposed to guarantee the finite time convergence of the system states to zero...

in this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. the order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. in addition, storage space is constrained and the problem ...

Inspired by a recent novel work of Good and Meddaugh, we establish fundamental connections between shadowing, finite order shifts, ultrametric complete spaces. We develop theory shifts type for infinite alphabets. call them order. the basic shadowing property in general metric spaces, exhibiting similarities differences with compact connect these two theories setting zero-dimensional showing th...

In this paper, we establish the following two results: (1) a skew translation generalized quadrangle of even order is quadrangle, (2) does not admit point regular group automorphisms. The first result confirms conjecture Payne (1975) based on earlier work Ott (2021), and second Ghinelli (1992).

We investigate alternating sign matrices that are not permutation matrices, but have finite order in a general linear group. classify all such examples of the form P + T , where is matrix and has four non-zero entries, forming square with entries 1 −1 each row column. show multiplicative orders these do always coincide those same size. pose problem identifying subgroups groups generated by matr...
