We present a tile system for assembling a counter of width K and height N = 2 on top of a seed-row in optimum time Θ(N). Our counter works at temperature 2. Earlier known constructions either took sub-optimal time or required temperature 3. Using existing techniques, our system for assembling a counter from a seed row can be extended into a system for assembling an N × N square in optimum time ...

Low density plantings complemented by natural regeneration is an increasingly common reforestation technique to ensure growth of a sufficient number of trees from desired species while maintaining natural processes such as succession. One such form of low density planting that aims at lowering establishment costs—oak clusters—has been developed as an alternative to row planting since the 1980s ...

a field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (hibiscus sabdariffa l.) in 2014/15 cropping season at wondo genet agricultural research center experimental site (at wondo genet station). two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, wg-hi...

INTRODUCTION: Shoulder motion following rotator cuff repair is unavoidable and may results in changes in tension on the repair and changes in compression forces at the rotator cuff footprint. We set out to determine how tension within the rotator cuff tendons and motion of the shoulder affect the footprint compression forces of a rotator cuff repair using multiple repair techniques. Ultimately,...

Deterministic algorithms are given for some computational problems that take as input a nonsingular polynomial matrix A over K[x], K an abstract field, including solving a linear system involving A and computing a row reduced form of A. The fastest known algorithms for linear system solving based on the technique of high-order lifting by Storjohann (2003), and for row reduction based on fast mi...

This study develops the foundation for a simple, yet efficient method for uncovering functional and approximate functional dependencies in relational databases. The technique is based upon the mathematical theory of partitions defined over a relation’s row identifiers. Using a levelwise algorithm the minimal non-trivial functional dependencies can be found using computations conducted on intege...

Classical discrete wavelet packet transforms are sensitive to changes in image orientation and translation. Therefore, it is hardly possible to extract rotation invariant features from images in the transform domain. This paper proposes several algorithms for invariant discrete wavelet decomposition to produce an invariant representation for an image. The procedure can be divided into several s...
