A posteriori error estimation and related adaptive mesh-refining algorithms have themselves proven to be powerful tools in nowadays scientific computing. Contrary to adaptive finite element methods, convergence of adaptive boundary element schemes is, however, widely open. We propose a relaxed notion of convergence of adaptive boundary element schemes. Instead of asking for convergence of the e...

RNA polymerase (RNAP) melts promoter DNA to form transcription-competent open promoter complex (RPo). Interaction of the RNAP σ subunit with non-template strand bases of a conserved -10 element (consensus sequence T-12A-11T-10A-9A-8T-7) is an important source of energy-driving localized promoter melting. Here, we used an RNAP molecular beacon assay to investigate interdependencies of RNAP inter...

Information now is an important element to every growing industry in the world. In order to keep up with other competitors, endless improvements in optimizing overall efficiency are needed. There still exist barriers that separate departments in PT. XYZ and cause limitation to the information sharing in the system. Open-Source Manufacturing Execution System (MES) presents as an IT-based applica...

To assess and optimise the effect of multi-layered trim for the reduction of noise and vibration transmission, design engineers greatly depend on CAE tools. Mostly, these are based on element based simulation techniques such as the Finite Element Method (FEM). In practise, however, these methods are limited to low-frequency simulations due to the strongly increasing computational cost with freq...

We consider player TWO of the game G1(A,B) when A and B are special classes of open covers of metrizable spaces. Our results give gametheoretic characterizations of the notions of a countable dimensional and of a strongly countable dimensional metric spaces. The selection principle S1(A,B) states: There is for each sequence (An : n ∈ N) of elements of A a corresponding sequence (bn : n ∈ N) suc...

In this paper, three-dimensional (3-D) open cloaks were designed based on the coordinate transformation method. When the transformation center point is close to the boundary of the cloaks, the material parameter tensors in the near-boundary areas of the cloaks approximate to those in the background, so the near-boundary areas can be designed to be open. Full wave simulations based on finite ele...

Push back design as a complex task, is one of the major steps in the open pit mines planning. Push backs can be generated by varying economic factors such as commodity price, mining cost, processing cost, etc. Another important issue in generating push backs is grade uncertainty, which can cause the problem be more complex. Conventional methods of push back design ignore grade uncertainty. To o...

In Open Problems #3 (Summer 1991), I mentioned several analogues or extensions of Edmonds' Branching Theorem. Let 0 (G; r) be the minimum number of edges that must be deleted to make some vertex of a digraph G unreachable from r, and let (G; r) be the analogous parameter for vertex deletion. Edmonds proved that G has 0 (G; r) edge-disjoint r-branchings in G, where an r-branching is a subgraph i...

An analytical model based on modal series expansion method for calculating transmission loss (TL) of compressor’s mufflers has been present in this paper. The approximately averaged pressure response value, obtained by calculating the weighted average pressure response value in the vicinity of the point source, is applied to derive the pressure response functions and four-pole parameters. There...

template, here we suggest to morph a standardized brain model onto the individual brains. By using the identical transformation function a standard MNI based three dimensional source model grid is transformed to an individual surface grid. Doing so each source grid knot is located at an individual position but represents a standardized MNI brain area. These individual but representative source ...
