Life Cycle Assessment of Individual Wood Biomass Heating Systems in Households
The use of solid fuels (wood biomass and coal) for heating of households continues to be common practice within European countries. Solid fuel combustion in households contributes more than 46% to total emissions of fine particulate matter. In this study, a life-cycle assessment (LCA) of firewood-based and pellet-based heating systems is performed. These two systems represent two different types of individual wood biomass heating systems. In the case of the firewood-based heating systems, it is analyzed a typical stove ...... (Impact assessment), ISO 14043 (Interpretation) [15]. Life-cycle assessment (LCA) is considered as an effective method to evaluate the greenhouse gas (GHG) emissions of a particular HS throughout its lifetime [9].

Parallel Bidirectionally Pretrained Taggers as Feature Generators
In a setting where multiple automatic annotation approaches coexist and advance separately but none completely solve a specific problem, the key might be in their combination and integration.

Terminology Acquisition and Description Using Lexical Resources and Local Grammars
Acquisition of new terminology from specific domains and its adequate description within terminological dictionaries is a complex task, especially for languages that are morphologically complex such as Serbian. In this paper we present an approach to solving this task semi-automatically on basis of lexical resources and local grammars developed for Serbian. Special attention is given to automatic inflectional class prediction for simple adjectives and nouns and the use of syntactic graphs for extraction of Multi-Word Unit (MWU) candidates for ...... frequency: 1. AXN – an adjective followed by a noun; the adjective and the noun have to agree in all four grammatical categories; e.g. zemni gas ‘natural gas’. 2. 2XN – a noun preceded by a word that does not inflect in the MWU. Usually it is a word used only in one or a few MWUs, a prefix or an adverb ...Cvetana Krstev, Ranka Stanković, Ivan Obradović, Biljana Lazić.
