4 ABSTRACT: Anaerobic digestion (AD) of the organic fraction of municipal solid waste (OFMSW) 5 is promoted as an energy source and more recently as a GHG mitigation measure. In this context, AD 6 systems operating at thermophilic temperatures (55-60C) – compared to mesophilic temperatures 7 (35-40C) – have the unique feature of producing hygienic soil conditioners with greater process 8 effici...

Radiotracer experiments are carried out in order to determine the mean residence time (MRT) as well as percentage of dead zone, V dead (%), in an integrated mixer consisting of Rushton and pitched blade turbine (PBT). Conventionally, optimization was performed by varying one parameter and others were held constant (OFAT) which lead to enormous number of experiments. Thus, in this study, a 4-fac...

Forests are complex ecological systems, characterised by multiple-scale structural and dynamical patterns which are not inferable from a system description that spans only a narrow window of resolution; this makes their investigation a difficult task using standard field sampling protocols. We segment a QuickBird image covering a beech forest in an initial stage of old-growthness – showing, acc...

One of the most important and effective factors in prioritizing high accident prone segments of roads for pedestrians is accident cause which up to now has been neglected in current methods. Since accidents are not additives due to various reasons, prioritizing these segments without considering the accident cause makes the selection of high accident prone segments inaccurate. In this paper, by...

The expressiveness of the C/C++ preprocessing facility enables the development of highly configurable source code. However, the usage of language constructs like macros also bears the potential of resulting in highly incomprehensible and unmaintainable code, which is due to the flexibility and the “cryptic” nature of the preprocessor language. This could be overcome if suitable analysis tools w...

The article defines the concept of "city transport system" and it’s subsystems. Social non-social (quantitative qualitative) indicators characteristics urban public evaluation systems as a whole are described. hierarchy regulatory legal framework for management directions its improvement analysed. order managing city at macro- meso-level is schematically depicted, main tasks bodies these levels...

In this paper the factor of safety (FS) and critical line-segments slip surface obtained by the Alternating Variable Local Gradient (AVLG) optimization method was presented as a new topic in 2D. Results revealed that the percentage of reduction in the FS obtained by switching from a circular shape to line segments was higher with the AVLG method than other methods. The 2D-AVLG optimization meth...

Abstract. The marketing activity of «MasloTrade» LLC, which operates in the field promotion and distribution lubricants markets Ukraine, was analyzed. It has been established that innovative high margin Flagship product is not mainstream, due to its price simple comparison with a similar product, therefore it quite logical Premium segment largest. determined possibility engineering support from...
