The quality of a watershed can be seen from the discharge river flow. Watershed also sedimentation found in water flows and bodies. Sedimentation is sediment produced by erosion process carried flow deposited place where velocity smaller than settling velocity. This research was conducted intake area Musi Hydroelectric Watershed, Ujan Mas District, Kepahiang Regency, Bengkulu Province August – ...

We describe calculations of bb production to next-to-next-to-leading order (NNLO) and next-to-next-to-leading logarithm (NNLL) near threshold in pp interactions. Our calculations are in good agreement with the bb total cross section measured by HERA-B. Factorization assumes it is possible to separate QCD cross sections into universal, non-perturbative parton densities and a perturbatively calcu...

In the springtime, young men’s thoughts turn to love, but old men begin to contemplate retirement. I have lost count now, but this spring will be either the fourth or fifth time I will have retired and I am now looking forward to the next things I want to do. When I was in my fifties, twenty years ago, I was worried about retirement, having seen what happened to people I knew when they were tos...

These short notes provide descriptions and references relative to the construction of parsing tables for SLR(1), for LR(1), and for LALR(1) grammars. 1 Notation and basic definitions Basic definitions and notational conventions are summerized below. A context-free grammar is a tuple G = (V, T, S,P), where the elements of the tuple represent, respectively, the vocabulary of terminal and nontermi...

For the first time the entire sequence of the mating behaviour of Antarctic krill (Euphausia superba) in the wild is captured on underwater video. This footage also provides evidence that mating can take place near the seafloor at depths of 400-700 m. This observation challenges the generally accepted concept of the pelagic lifestyle of krill. The mating behaviour observed most closely resemble...

We consider the problem of retrieving the k documents from a collection of strings where a given pattern P appears least often. This has potential applications in data mining, bioinformatics, security, and big data. We show that adapting the classical linear-space solutions for this problem is trivial, but the compressed-space solutions are not easy to extend. We design a new solution for this ...

About twenty years ago, many experts were still pessimistic about the possibility for making qualitative significant advancements in resolution improvement of the electron microscope. The basis for their scepticism was the Scherzer Theorem [1], which states that axially symmetric electromagnetic lenses have large intrinsic spherical and chromatic aberrations, limiting the resolution of an elect...
