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...

Though more diicult to program, distributed-memory parallel machines provide greater scalability than their shared-memory counterparts. Distributed Shared Memory (DSM) systems provide the abstraction of shared memory on a distributed machine. While DSMs provide an attractive programming model, they currently can not eeciently support all classes of scientiic applications. One such class are tho...

In this paper, the celluar automation model with FukuiIshibashi-type acceleration rule is used to study the inter-car spacing distribution for traffic flow. The method used in complex network analysis is applied to study the spacings distribution. By theoretical analysis, we obtain the result that the distribution of inter-car spacings follows power law when vehicle density is low and spacing i...

The accumulation slope is widely distributed in the mountainous area of China; this paper takes Chengdu–Lanzhou Railway as engineering background and analyzes stability mechanical properties anti-slip pile under symmetrical train loads. First, finite element software Midas GTS NX was used to analyze effect after support at different spacings, row distances, positions. Then, analysis results pil...

We consider a finite-difference approximation to the Cauchy problem for a firstorder hyperbolic partial differential equation using different mesh spacings in different portions of the domain. By reformulating our problem as a difference approximation to an initial-boundary value problem, we are able to use the theory of H. O. Kreiss and S. Osher to analyze the L3 stability of our scheme. 0. In...

Let (Cn)n≥0 be the Lucas sequence Cn+2 = aCn+1 +bCn for all n ≥ 0, where C0 = 0 and C1 = 1. For 1 ≤ k ≤ m− 1 let [ m k ] C = CmCm−1 · · ·Cm−k+1 C1 · · ·Ck be the corresponding C-nomial coefficient. When Cn = Fn is the Fibonacci sequence (the numbers [ m k ] F are called Fibonomials), or Cn = (qn − 1)/(q − 1), where q > 1 is an integer (the numbers [ m k ] q are called q-binomial, or Gaussian co...
