PENGARUH POLA PENGGERGAJIAN TERHADAP RENDEMEN DAN WAKTU MENGGERGAJI KAYU MERANTI (SHOREA SPP.) *)
Jurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2017 The effects of sawing pattern on recovery and sawing time was studied using 72 logs of meranti (Shorea spp.). The logs were divided into 4 grades i.e., Prime, First, Second and Local, each group consisting of 18 logs.

Determining Factors Behind the PageRank Log-Log Plot [PDF]
, 2007 We study the relation between PageRank and other parameters of information networks such as in-degree, out-degree, and the fraction of dangling nodes. We model this relation through a stochastic equation inspired by the original definition of PageRank.

Bell Numbers, Log-Concavity, and Log-Convexity
Acta Applicandae Mathematica, 2000 Let $\{b_{k}(n)\}_{n=0}^{\infty}$ be the Bell numbers of order $k$. It is proved that the sequence $\{b_{k}(n)/n!\}_{n=0}^{\infty}$ is log-concave and the sequence $\{b_{k}(n)\}_{n=0}^{\infty}$ is log-convex, or equivalently, the following inequalities hold for all $n\geq 0$, $$1\leq {b_{k}(n+2) b_{k}(n) \over b_{k}(n+1)^{2}} \leq {n+2 \over n+1 ...

Occurrence of decay in aspen logs
Silva Fennica, 1978 At three Finnish match factories 1,629 aspen logs were measured (see Kärkkäinen and Salmi 1978). When the estimation was based on the condition of the butt cross section of a log, less than half of the logs were sound without any discoloration or decay.

Log–canonical forms and log canonical singularities
Mathematische Nachrichten, 2003 AbstractFor a normal subvarietyVof ℂnwith a good ℂ*–action we give a simple characterization for when it has only log canonical, log terminal or rational singularities. Moreover we are able to give formulas for the plurigenera of isolated singular points of such varieties and of the logarithmic Kodaira dimension ofV\{0}.

Determination of conversion factors for pine and spruce logs in stacks
Leśne Prace Badawcze, 2019 The aim of this article was to determine the conversion factors for stacked pine and spruce logs with a length of 3–6 m. To this end, we measured stacks and their logs of a total of 3322.12 steres of pine logs and 1468.46 steres of spruce logs.
