A Gis Based Graph Oriented Algorithmic Model for Poly-Optimization of Waste Management System

Abstract

The methodology of modelling and object analysis of management systems includes, inter alia, operations connected with the definition of special object types being an imitation of components (objects-sources of waste generation, objects for waste neutralisation, networks of roads, natural environment components, waste substances, etc.) [4, 6-7]. Since the systems are investigated in the GIS technology, some objects are assigned attributes of spatial representation (location coordinates, geometric and graphic attributes used for their recording on a map). Operations performed on the models of individual-class objects (e.g. topological operations) are interpreted (using object-related terminology) as the so-called methods (functions and procedures) which are in fact computer implementations of a range of algorithms used in system analyses

The Use of Fragmented, Worn-Out Car Side Windows as an Aggregate for Cementitious Composites

“…In connection with this, the scientific discussions more and more often draw attention to the issue of the so-called ecological security. The priority here is proper waste management, and in particular, taking actions so that the largest possible quantities of wastes can be re-used [1,2]. This activity is not only intended to prevent the formation of unwanted waste heaps, but also aims to reduce the extraction of natural resources.…”

THE IMPACT OF CONSTRUCTION WORKS CONDUCTED ON THE ROUTE DTŚ ON A LOCAL AIR QUALITY EVALUATED WITH THE USE OF NO2 MEASUREMENTS

“…For instance Helms and Heidt [17] found that up to 6% of NO x (and up to 10% of PM) traffic related emissions in Germany are caused by mobile construction machinery. Under the assumption, that concentrations in the air in a case of emission sources of low height, are proportional to emissions (what is fulfilled roughly in city-centers) and taking into consideration the 48% share of NO x emission from road-transport sector in total [24,25,26,27] (39% road transport + 9% nonroad transport), the share of construction machines in total NO x concentration yields about 3%. The similar calculations made by Millstein and Harley [18], which assigned 11% of NO x (and 14% of total 1-hour NO 2 level in the air in the vicinity of the conducted construction works was not exceeded.…”

A Concept of the Gasification Plant for Selected Organic Waste

“…Recovery of energy from the municipal waste should constitute a method that is complementary to recycling and leads to the decrease of the stream of waste directed to landfills. From the energetic and economic point of view, some fractions selected from the stream of municipal waste constitute precious energetic material [8][9][10][11][12][13]. This management method has another advantage -it can cover all types of waste -especially non-uniform and contaminated for example with organic fraction [13][14][15][16][17].…”
