The clean graph of a commutative ring
(Charles Babbage Research Centre, 2017)
To gain a better understanding of clean rings and their relatives, the clean graph of a commutative ring with identity is introduced and its various properties established. Further investigation of clean graphs leads to ...
The maximum number of P-vertices of some nonsingular double star matrices
(Elsevier B.V., 2013)
In this short note, we construct a nonsingular matrix A whose graph is a double star of order n >= 4 with n - 2 P-vertices. This example leads to a positive answer, for n >= 6, to a last open question proposed recently by ...
s-nil-čisti prsteni matrica
(VIII simpozijum "Matematika i primene", 11-2017, 2017)
Analiziraju se uslovi pod kojima se matrica nad prstenom može razložiti na zbir idempotentnih i jedne nilpotentne matrice.
The role of conceptual hydrologic model calibration in climate change impact on water resources assessment
(IWA Publishing, 2016)
Assessment of climate change (CC) impact on hydrologic regime requires a calibrated rainfall-runoff model, defined by its structure and parameters. The parameter values depend, inter alia, on the calibration period. This ...
A simple numerical method for snowmelt simulation based on the equation of heat energy
(IWA Publishing, 2016)
This paper presents one-dimensional numerical model for snowmelt/accumulation simulations, based on the equation of heat energy. It is assumed that the snow column is homogeneous at the current time step; however, its ...
Indirect effect of the helmert condensation reduction over the territory of Serbia
(International Multidisciplinary Scientific Geoconference, 2017)
In the process of geoid determination one of the most important problems is to determine the effect of topographic masses. Traditionally, solving that particular problem started with the reduction of gravity on the geoid ...
Predicting land use change with data-driven models / Predviđanje promena u korišćenju zemljišta primenom modela vođenih podacima (DATA-DRIVEN MODELS)
(Универзитет у Београду, Грађевински факултет, 2014)
One of the main tasks of data-driven modelling methods is to induce arepresentative model of underlying spatial - temporal processes using past dataand data mining and machine learning approach. As relatively new methods,known ...
Geometrically nonlinear transient analysis of delaminated composite and sandwich plates using a layerwise displacement model with contact conditions
(Elsevier Ltd, 2015)
In the paper, a computational model for the transient response of laminated composite and sandwich plates with existing zones of partial delamination, subjected to dynamic pulse loading is proposed. Laminated composite and ...
Conservation of resources in the pulp and paper industry derived from cleaner production approach
(Resources Conservation and Recycling, 2011)
This paper analyses the utilization of water and recycled fiber from waste paper for the production in one Serbian cardboard mill. Water and fiber consumption, wastewater generation and its characteristics, as well as ...
Review of the methods for analysis of flat slabs / Prikaz metoda za proračun ploča direktno oslonjenih na stubove
(Građevinski fakultet Subotica, Subotica, 2016)
The paper analyzes the results of reinforced concrete flat slabs, using different methods based on the theory of elasticity and theory of plasticity. Were considered three methods: stripe method, method according to ...
