Urbanization has significantly increased over the last two centuries. In year 1800 only 2% of people lived in cities, while 1900 this percent to 12%. Recent studies indicate that 2008 more than 50% world population urban areas, with percentage expected reach 75% by 2030. Urban land cover occupies or 3% earth surface, yet it been recognized growth is associated many socioeconomic and environment...

Due to their positive technical properties, such as high chemical resistance and mechanical durability, epoxy resins are moving into more and more deployment areas. Significant applications in the construction industry are coatings for industrial flooring, concrete restoration, corrosion proofing, adhesives for tiles, and joint mortar. Unfortunately, the growing use of these products is also co...

making an informed decision with regards to a suitable business location or site selection for organizations is becoming challenging for business decision makers globally; and even more challenging in business environment that are saddled with uncertainties. the continues raise of multiple criteria variation of site preferences has also necessitated the application of advanced decision making t...

A method for shape reconstruction from contours is presented using isotopic deformation. The reconstructed shape is free of self-intersection and it can incorporate given feature correspondences. The method automatically adds vertices, where necessary, to satisfy these requirements. A new method for handling bifurcation is also proposed, which can handle cases that are problematic for some othe...

Image-Space Sheet-Buffered Splatting is a popular high quality volume-rendering technique specially suitable for zoomed views of the data. On the contrary to other splatting approaches, it processes the voxels in slabs perpendicular to the viewing direction. Recently, a GPU design of this method has been proposed that considerably accelerates the rendering stage. However, the bottleneck of the ...

The four best known DNA sequencing techniques are reviewed. Important practical issues covered are read-length, speed, accuracy, throughput, cost, as well as the automation of sample handling and preparation. The methods reviewed are: (i) the Sanger method and its most important variants (enzymic methods); (ii) the Maxam & Gilbert method and other chemical methods; (iii) the Pyrosequencing meth...

Decision making about outsourcing or insourcing of manufacturing activities is a type of multiple criteria decision making (MCDM) problem, which requires considering quantitative and qualitative factors as evaluation criteria simultaneously. Therefore, a suitable MCDM method can be useful in this area as it can consider the interactions among quantitative and qualitative criteria. The analytic...

The enzymatic method for ammonia with the Du Pont Automatic Clinical Analyzer was tested in our laboratory. The method is very suitable for urine samples although the method was released by Du Pont only for plasma samples. The results correlated well with those obtained by a method based on the Berthelot indophenol reaction and by a method based on the use of an ammonium electrode, which has an...

this paper presents approximate analytical solutions for nonlinear oscillators using the multi-step homotopy analysis method (msham). the proposed scheme is only a simple modification of the homotopy analysis method, in which it is treated as an algorithm in a sequence of small intervals (i.e. time step) for finding accurate approximate solutions to the corresponding problems. several illustrat...
